Abstract
Standard adjuvant treatment for locally advanced gastric cancer (LAGC) is regionally different. Whereas perioperative chemotherapy is the standard in Western populations, D2 gastrectomy followed by adjuvant chemotherapy has been the standard in East Asia. Recently, the pivotal phase 3 PRODIGY and RESOLVE studies have demonstrated survival benefits of adding neoadjuvant chemotherapy to surgery followed by adjuvant chemotherapy over up-front surgery followed by adjuvant chemotherapy in Asian patients. Based on these results, neoadjuvant chemotherapy is considered one of the viable options for patients with LAGC. In this review, various aspects of neoadjuvant chemotherapy will be discussed for its optimal application in Asia. Candidates for neoadjuvant chemotherapy should be carefully chosen in consideration of the inaccurate aspects of radiological clinical staging and its potential benefit over up-front surgery followed by a decision on adjuvant chemotherapy according to the pathological stage. Efforts should continuously be made to optimally apply neoadjuvant chemotherapy to patients with LAGC, considering various factors, including a more accurate radiological assessment of the tumor burden and the optimization of post-operative chemotherapy. Future neoadjuvant trials involving novel agents for Asian patients should be designed based on proven Asian regimens rather than adopting Western regimens.

Abstract
BACKGROUND We report the final results of the randomized phase 2 FIGHT trial that evaluated bemarituzumab, a humanized monoclonal antibody selective for fibroblast growth factor receptor 2b (FGFR2b), plus mFOLFOX6 in patients with FGFR2b-positive (2 + /3 + membranous staining by immunohistochemistry), HER-2-negative gastric or gastroesophageal junction cancer (GC). METHODS Patients received bemarituzumab (15 mg/kg) or placebo once every 2 weeks with an additional bemarituzumab (7.5 mg/kg) or placebo dose on cycle 1 day 8. All patients received mFOLFOX6. The primary endpoint was investigator-assessed progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate, and safety. Efficacy was evaluated after a minimum follow-up of 24 months. RESULTS In the bemarituzumab-mFOLFOX6 (N = 77) and placebo-mFOLFOX6 (N = 78) arms, respectively, 59.7% and 66.7% of patients were FGFR2b-positive in ≥ 10% of tumor cells. The median PFS (95% confidence interval [CI]) was 9.5 months (7.3-13.7) with bemarituzumab-mFOLFOX6 and 7.4 months (5.7-8.4) with placebo-mFOLFOX6 (hazard ratio [HR], 0.72; 95% CI 0.49-1.08); median OS (95% CI) was 19.2 (13.6-24.2) and 13.5 (9.3-15.9) months, respectively (HR 0.77; 95% CI 0.52-1.14). Observed efficacy in FGFR2b-positive GC in ≥ 10% of tumor cells was: PFS: HR 0.43 (95% CI 0.26-0.73); OS: HR 0.52 (95% CI 0.31-0.85). No new safety findings were reported. CONCLUSIONS In FGFR2b-positive advanced GC, the combination of bemarituzumab-mFOLFOX6 led to numerically longer median PFS and OS compared with mFOLFOX6 alone. Efficacy was more pronounced with FGFR2b overexpression in ≥ 10% of tumor cells. Confirmatory phase 3 trials are ongoing (NCT05052801, NCT05111626). CLINICAL TRIAL REGISTRATION NCT03694522.

Abstract
BACKGROUND In the phase III HIMALAYA study (NCT03298451) in unresectable hepatocellular carcinoma (uHCC), STRIDE (Single Tremelimumab Regular Interval Durvalumab) significantly improved overall survival (OS) versus sorafenib; durvalumab monotherapy was noninferior to sorafenib for OS. Results reported herein are from a 4-year updated OS analysis of HIMALAYA. PATIENTS AND METHODS Participants with uHCC and no previous systemic treatment were randomized to STRIDE (n = 393), durvalumab (n = 389), or sorafenib (n = 389). The updated data cut-off was 23 January 2023. OS and serious adverse events (AEs) were assessed. Additionally, baseline characteristics and subsequent therapies were analyzed in long-term survivors (≥36 months beyond randomization). RESULTS For STRIDE, durvalumab, and sorafenib, median [95% confidence interval (CI)] follow-up was 49.12 months (46.95-50.17 months), 48.46 months (46.82-49.81 months), and 47.31 months (45.08-49.15 months), respectively. OS hazard ratio (95% CI) for STRIDE versus sorafenib was 0.78 (0.67-0.92). The 36-month OS rate for STRIDE was 30.7% versus 19.8% for sorafenib. The 48-month OS rate remained higher for STRIDE at 25.2%, versus 15.1% for sorafenib. The long-term OS benefit of STRIDE was observed across clinically relevant subgroups and was further improved in participants who achieved disease control. Long-term survivors with STRIDE (n = 103) included participants across clinically relevant subgroups, and 57.3% (59/103) had no reported subsequent anticancer therapy. No new serious treatment-related AEs occurred with STRIDE from the primary analysis (17.5%; 68/388). Durvalumab maintained OS noninferiority to sorafenib and no late-onset safety signals were identified. CONCLUSIONS These data represent the longest follow-up to date in phase III studies in uHCC. The unprecedented 3- and 4-year OS rates reinforce the sustained long-term OS benefit of STRIDE versus sorafenib. STRIDE maintained a tolerable yet differentiated safety profile from other current uHCC therapies. Results continue to support the long-term benefits of STRIDE in a diverse population, reflective of uHCC globally.

Abstract
BACKGROUND We examined the impact of mismatch repair (MMR) status on efficacy of first-line fluoropyrimidine plus platinum (FP) chemotherapy in patients with HER2-negative metastatic, recurrent, or unresectable gastric cancer (mGC). METHODS Patients with mGC receiving first-line FP between 2015 and 2018 at Asan Medical Center, Korea, were reviewed. We evaluated the clinical characteristics and the efficacy of chemotherapy according to MMR status in patients with available immunohistochemistry results. RESULTS Of 895 patients, we analyzed 543 with available MMR protein expression results, and deficient MMR (dMMR) was detected in 4.4% (n = 24). Patients with dMMR exhibited a significantly higher median age than those with proficient MMR (pMMR) (64 vs. 58 years, p = 0.044). No signet ring cell carcinoma (SRCC) was detected among dMMR tumors, whereas SRCC was found in 17.5% of pMMR. Objective response rate was 27.3% in dMMR and 34.3% in pMMR (p = 0.556). No difference in progression-free survival was noted between patients with dMMR and pMMR (median, 5.6 vs. 5.8 months, p = 0.266). Patients with dMMR tended to have better overall survival than those with pMMR although this difference was not statistically significant (median, 17.9 vs. 12.2 months, p = 0.183). CONCLUSIONS Efficacy of first-line FP was not different by MMR status in mGC patients.

Abstract
BACKGROUND Rivoceranib is an oral, selective tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2. ANGEL (NCT03042611) was a global, randomized, double-blinded, placebo-controlled, phase 3 study evaluating rivoceranib as 3rd-line or ≥4th-line therapy in patients with advanced/metastatic gastric or gastroesophageal junction (GEJ) cancer. METHODS Patients had failed ≥2 lines of chemotherapy and were randomized 2:1 to rivoceranib 700 mg once daily or placebo with best supportive care. PRIMARY ENDPOINT overall survival (OS) in the intention-to-treat population. Secondary endpoints: progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR) by blinded independent central review (BICR). RESULTS In total, 460 patients (rivoceranib n = 308, placebo n = 152) were enrolled. OS was not statistically different for rivoceranib versus placebo (median 5.78 vs. 5.13 months; hazard ratio [HR] 0.93, 95% CI 0.74-1.15; p = 0.4724). PFS by BICR (median 2.83 vs. 1.77 months; HR 0.58, 95% CI 0.47-0.71; p < 0.0001), ORR (6.5% vs. 1.3%; p = 0.0119), and DCR (40.3 vs. 13.2%; p < 0.0001) were improved with rivoceranib versus placebo. In patients receiving ≥4th-line therapy, OS (median 6.34 vs. 4.73 months; p = 0.0192) and PFS by BICR (median 3.52 vs. 1.71 months; p < 0.0001) were improved with rivoceranib versus placebo. The most common grade ≥ 3 treatment-emergent adverse events with rivoceranib were hypertension (17.9%), anemia (10.4%), aspartate aminotransferase increased (9.4%), asthenia (8.5%), and proteinuria (7.5%). CONCLUSIONS This study did not meet its primary OS endpoint. Compared to placebo, rivoceranib improved PFS, ORR, and DCR. Rivoceranib also improved OS in a prespecified patient subgroup receiving ≥4th-line therapy.

Abstract
INTRIGUE was an open-label, phase 3 study in adult patients with advanced gastrointestinal stromal tumor who had disease progression on or intolerance to imatinib and who were randomized to once-daily ripretinib 150 mg or sunitinib 50 mg. In the primary analysis, progression-free survival (PFS) with ripretinib was not superior to sunitinib. In clinical and nonclinical studies, ripretinib and sunitinib have demonstrated differential activity based on the exon location of KIT mutations. Therefore, we hypothesized that mutational analysis using circulating tumor DNA (ctDNA) might provide further insight. In this exploratory analysis (N = 362), baseline peripheral whole blood was analyzed by a 74-gene ctDNA next-generation sequencing-based assay. ctDNA was detected in 280/362 (77%) samples with KIT mutations in 213/362 patients (59%). Imatinib-resistant mutations were found in the KIT ATP-binding pocket (exons 13/14) and activation loop (exons 17/18). Mutational subgroup assessment showed 2 mutually exclusive populations with differential treatment effects. Patients with only KIT exon 11 + 13/14 mutations (ripretinib, n = 21; sunitinib, n = 20) had better PFS with sunitinib versus ripretinib (median, 15.0 versus 4.0 months). Patients with only KIT exon 11 + 17/18 mutations (ripretinib, n = 27; sunitinib, n = 25) had better PFS with ripretinib versus sunitinib (median, 14.2 versus 1.5 months). The results of this exploratory analysis suggest ctDNA sequencing may improve the prediction of the efficacy of single-drug therapies and support further evaluation of ripretinib in patients with KIT exon 11 + 17/18 mutations.

Abstract
Purpose To report the results from an early-phase study of rivoceranib, an oral tyrosine kinase inhibitor highly selective for vascular endothelial growth factor receptor 2, in patients with advanced solid tumors. Materials and Methods In this open-label, single-arm, dose-escalating, multicenter three-part phase 1/2a trial, patients had advanced solid tumors refractory to conventional therapy. Part 1 evaluated the safety and pharmacokinetics of five ascending once-daily doses of rivoceranib from 81 mg to 685 mg. Part 2 evaluated the safety and antitumor activity of once-daily rivoceranib 685 mg. Part 3 was conducted later, due to lack of MTD determination in part 1, to evaluate the safety and preliminary efficacy of once-daily rivoceranib 805 mg in patients with unresectable or advanced gastric cancer. Results A total of 61 patients were enrolled in parts 1 (n=25), 2 (n=30), and 3 (n=6). In parts 1 and 2, patients were white (45.5%) or Asian (54.5%), and 65.6% were male. The most common grade ≥3 adverse events (AEs) were hypertension (32.7%), hyponatremia (10.9%), and hypophosphatemia (10.9%). The overall response rate (ORR) was 15.2%. In part 3, dose-limiting toxicities occurred in 2 out of 6 patients: grade 3 febrile neutropenia decreased appetite, and fatigue. The ORR was 33%. Conclusion The recommended phase 2 dose of rivoceranib was determined to be 685 mg once daily, which showed adequate efficacy with a manageable safety profile. (NCT01497704 and NCT02711969).

Abstract
PURPOSE Heterogeneous human epidermal growth factor receptor 2 (HER2) overexpression in gastric cancer may lead to a misdiagnosis of HER2 status. Accurate assessment of HER2 status is essential for optimal treatment as novel HER2-directed agents are being investigated in various clinical settings. We evaluated the usefulness of HER2 re-assessment following progression on first-line treatment in initially HER2-negative advanced gastric cancer (AGC) patients. MATERIALS AND METHODS We enrolled 177 patients with baseline HER2-negative AGC and performed HER2 re-assessment after progression on first-line treatment from February 2012 to June 2016 at Asan Medical Center, Seoul, Korea. The re-assessed HER2 status was analyzed with baseline HER2 status and clinical characteristics. RESULTS The median age was 54 years (range, 24 to 80 years), and 123 patients (69.5%) were men. Seven patients (4.0%) were HER2-positive on the re-assessment. Patients with baseline HER2 negativity confirmed by a single test (n=100) had a higher HER2-positive re-assessment rate compared to those who had repeated baseline testing (n=77) (5.0% vs. 2.6%). Among the patients with single baseline HER2 testing, the rate was higher in patients with baseline HER2 immunohistochemistry (IHC) 1+ compared to those with IHC 0 (13.4% vs. 3.6%). CONCLUSION Overall, 4.0% of patients with baseline HER2-negative AGC were HER2-positive on re-assessment, and the HER2-positive re-assessment rate was higher among patients who had a single test at baseline. HER2 re assessment may be considered for initially HER2-negative patients to determine their eligibility for HER2-directed therapy, particularly if their HER2 negativity was determined by a single test, especially if they had a single baseline HER2 IHC 1+ test.

Abstract
BACKGROUND Epstein-Barr virus-associated gastric cancer (EBVaGC) is a distinct molecular subgroup showing excellent outcomes after surgery for localized disease. Prominent immune cell infiltration in EBVaGC reflects the immunogenicity of Epstein-Barr virus (EBV) and, as suggested by some investigators, responsiveness to immune checkpoint inhibitors in the palliative setting. However, few data are available on the prevalence, clinical characteristics, and prognosis of EBVaGC patients receiving palliative cytotoxic chemotherapy. METHODS In this retrospective study, we identified 1061 patients with metastatic, recurrent, or locally advanced unresectable gastric cancer (GC) who started first-line fluoropyrimidine/platinum (FP) doublet chemotherapy with or without trastuzumab from January 2015 to August 2018. For 766 patients with available tumor tissue, the presence of EBV in cancer cells was evaluated by EBV-encoded RNA in situ hybridization and correlated with clinical characteristics and treatment outcomes. RESULTS Among the patients evaluated (n = 766), 40 (5.0%) were EBV-positive. EBVaGC was associated with male sex (p = 0.009) and lower neutrophil-lymphocyte ratio (NLR < 2.46, p = 0.03). Efficacy of first-line FP chemotherapy, in terms of response rate ad progression-free survival (PFS), did not differ between EBVaGC and EBV-negative GC (overall response rate: 53.8% vs. 51.8%, p = 0.99; median PFS: 6.4 vs. 6.7 months, p = 0.90). However, overall survival tended to be better with EBVaGC than EBV-negative GC (16.4 vs. 14.0 months, p = 0.07). CONCLUSIONS EBVaGC accounted for 5% of metastatic/unresectable GCs. While EBVaGC was not associated with better response to or PFS following first-line cytotoxic chemotherapy, it showed a trend toward better overall survival.

Abstract
BACKGROUND The benefit of adjuvant chemotherapy for locally advanced gastric cancer (LAGC) patients with DNA mismatch repair (MMR) deficiency (D-MMR) is controversial due to concerns about its potential detrimental effect. The PRODIGY trial showed the survival benefit of adding preoperative docetaxel, oxaliplatin, and S-1 (DOS) to surgery plus postoperative S-1 for LAGC patients. In this sub-analysis, we evaluated the benefit of preoperative DOS according to MMR status. METHODS Among patients enrolled in the PRODIGY trial treated with either preoperative DOS followed by surgery and postoperative S-1 (CSC arm), or surgery and postoperative S-1 (SC arm) at Asan Medical Center (n = 249), those in the full analysis set with available tissue to assess MMR status were included in the present analysis. RESULTS A total of 231 patients (CSC arm, n = 108; SC arm, n = 123) were included (median age, 58 years [range, 27-75]), and 21 patients (CSC arm, n = 8 [7.4%]; SC arm, n = 13 [10.6%]) had D-MMR tumors. Progression-free survival and overall survival tended to be superior in the CSC arm than in the SC arm among D-MMR patients (HR 0.48 [95% CI 0.09-2.50]; log-rank P = 0.37 and HR 0.55 [95% CI 0.11-2.86]; log-rank P = 0.46, respectively), as well as among proficient MMR (P-MMR) patients (HR 0.68 [95% CI 0.46-1.03]; log-rank P = 0.07 and HR 0.75 [95% CI 0.49-1.14]; log-rank P = 0.17, respectively). CONCLUSION Preoperative DOS followed by surgery and postoperative S-1 may be considered a treatment option for LAGC patients regardless of MMR status.

Abstract
PURPOSE In the INTRIGUE trial, ripretinib showed no significant difference versus sunitinib in progression-free survival for patients with advanced gastrointestinal stromal tumour (GIST) previously treated with imatinib. We compared the impact of these treatments on health-related quality of life (HRQoL). PATIENTS AND METHODS Patients were randomised 1:1 to once-daily ripretinib 150 mg or once-daily sunitinib 50 mg (4 weeks on/2 weeks off). Patient-reported outcomes were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer-30 (EORTC QLQ-C30) questionnaire at day (D)1, and D29 of all cycles until treatment discontinuation. Change from baseline was calculated. Time without symptoms or toxicity (TWiST) was estimated as the mean number of days without progression, death, or grade ≥3 treatment-emergent adverse events per patient over 1 year of follow-up. RESULTS Questionnaire completion at baseline was 88.1% (199/226) for ripretinib and 87.7% (199/227) for sunitinib and remained high for enrolled patients throughout treatment. Patients receiving sunitinib demonstrated within-cycle variation in self-reported HRQoL, corresponding to the on/off dosing regimen. Patients receiving ripretinib reported better HRQoL at D29 assessments than patients receiving sunitinib on all scales except constipation. HRQoL was similar between treatments at D1 assessments, following 2 weeks without treatment for sunitinib patients. TWiST was greater for ripretinib patients (173 versus 126 days). CONCLUSION Patients receiving ripretinib experienced better HRQoL than patients receiving sunitinib during the dosing period and similar HRQoL to patients who had not received sunitinib for 2 weeks for all QLQ-C30 domains except constipation. Ripretinib may provide clinically meaningful benefit to patients with advanced GIST previously treated with imatinib.

Abstract
Objective: To investigate the correlation between adjuvant chemotherapy with platinum-containing regimens and DNA damage repair (DDR) defects in early-stage triple negative breast cancer (TNBC), and to provide a basis for precise treatment of TNBC. Methods: Next-generation sequencing (NGS) testing was performed on postoperative breast cancer specimens selected from the Cancer Hospital of Chinese Academy of Medical Sciences from June 2009 to October 2015 to analyze the correlation between DDR gene variants and the efficacy of adjuvant chemotherapy with TNBC platinum-containing regimens, and thus to screen the superior population for adjuvant chemotherapy with TNBC platinum-containing regimens. The study used t-test, χ(2) test, Fisher's exact test, rank sum test and multifactorial logistic analysis to assess the associations between mutated genes and clinicopathological characteristics and prognosis, and Log-rank test and Cox proportional risk model were used for survival and correlation analysis. Results: NGS results were successfully obtained in 149 patients (74 in the platinum-containing group and 75 in the platinum-free group), with a 97.3% (145/149) DDR gene mutation rate and a median number of 4 mutations in all patients. 5-year disease-free survival (DFS) was 85.4% and 75.0% for patients with DDR gene mutations and DDR gene wild-type, respectively, without statistical difference (P=0.825). The 5-year DFS rates of patients with homologous recombination repair (HRR) pathway mutation were 84.6% in platinum-containing (TCb) group and 84.9% in platinum-free (EC-T) group (P=0.554), respectively. The 5-year DFS rates of patients with and without mutations in the platinite-containing HRR pathway were 84.9% and 85.0%, respectively (P=0.751). The number of DDR pathways with mutations and the number of DDR gene mutations were not associated with prognosis (both P>0.05). PIK3CA mutation patients in TCb group had a worse prognosis than wild-type patients (5-year DFS were 71.4% and 88.1%, P=0.037), and KMT2D mutation patients in EC-T group had a worse prognosis than wild-type patients (5-year DFS were 76.9% and 86.8%, P=0.039). Conclusions: DDR gene variation is common in TNBC, more clinical studies are needed to prove whether DDR variation can serve as effective biomarkers for treatment with platinum.

Abstract
The role of poroelasticity on the functional performance of articular cartilage has been established in the scientific literature since the 1960s. Despite the extensive knowledge on this topic there remain few attempts to design for poroelasticity and to our knowledge no demonstration of an engineered poroelastic material that approaches the physiological performance. In this paper, we report on the development of an engineered material that begins to approach physiological poroelasticity. We quantify poroelasticity using the fluid load fraction, apply mixture theory to model the material system, and determine cytocompatibility using primary human mesenchymal stem cells. The design approach is based on a fiber reinforced hydrated network and uses routine fabrication methods (electrohydrodynamic deposition) and materials (poly[ɛ-caprolactone] and gelatin) to develop the engineered poroelastic material. This composite material achieved a mean peak fluid load fraction of 68%, displayed consistency with mixture theory, and demonstrated cytocompatibility. This work creates a foundation for designing poroelastic cartilage implants and developing scaffold systems to study chondrocyte mechanobiology and tissue engineering. STATEMENT OF SIGNIFICANCE: Poroelasticity drives the functional mechanics of articular cartilage (load bearing and lubrication). In this work we develop the design rationale and approach to produce a poroelastic material, known as a fiber reinforced hydrated network (FiHy™), that begins to approach the native performance of articular cartilage. This is the first engineered material system capable of exceeding isotropic linear poroelastic theory. The framework developed here enables fundamental studies of poroelasticity and the development of translational materials for cartilage repair.

Abstract
BACKGROUND Neoadjuvant treatment is recommended for large GISTs due to their friability and risk of extensive operations; however, studies on the indications and long-term results of this approach are lacking. METHODS Patients with large (≥ 10 cm) gastric GISTs were enrolled from multiple centers in Korea and Japan after a pathologic confirmation of c-KIT ( +) GISTs. Imatinib (400 mg/d) was given for 6-9 months preoperatively, and R0 resection was intended. Postoperative imatinib was given for at least 12 months and recommended for 3 years. RESULTS A total of 56 patients were enrolled in this study, with 53 patients receiving imatinib treatment at least once and 48 patients undergoing R0 resection. The 5-year overall survival and progression-free survival rates were 94.3% and 61.6%, respectively. Even patients with stable disease by RECIST criteria responded well to preoperative imatinib treatment and could undergo R0 resection, with most being evaluated as partial response by CHOI criteria. The optimal reduction in tumor size was achieved with preoperative imatinib treatment for 24 weeks or more. No resumption of imatinib treatment was identified as an independent prognostic factor for recurrence after R0 resection. No additional size criteria for a higher risk of recurrence were identified in this cohort with a size of 10 cm or more. CONCLUSIONS Neoadjuvant imatinib treatment is an effective treatment option for gastric GISTs 10 cm or larger. Postoperative imatinib treatment is recommended even after R0 resection to minimize recurrence.

Abstract
BACKGROUND Imatinib re-challenge is one of the available therapeutic options for patients with treatment-refractory gastrointestinal stromal tumours (GIST). Intermittent dosing of imatinib was suggested to delay outgrow of the imatinib-resistant clones in a preclinical study, and it could potentially reduce the adverse events. METHODS A randomised phase 2 study was performed to evaluate the efficacy and safety of a continuous or intermittent imatinib schedule in GIST patients whose disease had progressed to at least imatinib and sunitinib. RESULTS Fifty patients were included in the full analysis set. The disease control rate at 12 weeks was 34.8% and 43.5%, and median progression-free survival was 1.68 and 1.57 months in the continuous and intermittent groups, respectively. The frequency of diarrhoea, anorexia, decreased neutrophil, or dysphagia was lower in the intermittent group. The scores for global health status/quality of life was not significantly deteriorated over the 8 weeks in both groups. CONCLUSIONS The intermittent dosage did not improve the efficacy outcomes as compared to the continuous dosage, but showed slightly better safety profiles. Given the limited efficacy of imatinib re-challenge, intermittent dosage may also be considered in clinical circumstances where standard fourth-line agent is unavailable or all other viable treatments failed.

Abstract
BACKGROUND Current guidelines recommend indefinite imatinib treatment for advanced gastrointestinal stromal tumor (GIST) patients. Imatinib-refractory progression-free survival (PFS) and overall survival were previously reported not to differ between GIST patients who interrupted imatinib and those who did not. METHODS Clinical outcomes of 77 consecutive patients with recurrent or metastatic GIST who interrupted imatinib treatment after maintaining years of imatinib treatment in the absence of gross tumor lesions were retrospectively analyzed. Associations between clinical factors and progression-free survival (PFS) following imatinib interruption were analyzed. RESULTS The median time from the absence of gross tumor lesions to imatinib interruption was 61.5 months. Since imatinib interruption, the median PFS was 19.6 months, and 4 patients (26.3%) remained progression-free for longer than 5 years. Among the patients who had progressive disease following the interruption, imatinib re-introduction led to an 88.6% objective response rate and a 100% disease control rate. Complete removal of the initial gross tumor lesion(s) and complete removal of the residual gross tumor lesion(s) by local treatment (vs. no local treatment or residual lesions after local treatment) were independently associated with favorable PFS. CONCLUSION Interruption of imatinib following prolonged maintenance in the absence of gross tumor lesions led to disease progression in the majority of cases. However, re-introduction of imatinib resulted in effective tumor control. Unmaintained remission seems to be possible in some patients with metastatic or recurrent GIST after a prolonged remission with imatinib if there is complete removal of any gross tumor lesions.

Abstract
BACKGROUND Zolbetuximab, a monoclonal antibody targeting claudin-18 isoform 2 (CLDN18.2), has shown efficacy in patients with CLDN18.2-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma. We report the results of the SPOTLIGHT trial, which investigated the efficacy and safety of first-line zolbetuximab plus mFOLFOX6 (modified folinic acid [or levofolinate], fluorouracil, and oxaliplatin regimen) versus placebo plus mFOLFOX6 in patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma. METHODS SPOTLIGHT is a global, randomised, placebo-controlled, double-blind, phase 3 trial that enrolled patients from 215 centres in 20 countries. Eligible patients were aged 18 years or older with CLDN18.2-positive (defined as ≥75% of tumour cells showing moderate-to-strong membranous CLDN18 staining), HER2-negative (based on local or central evaluation), previously untreated, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma, with radiologically evaluable disease (measurable or non-measurable) according to Response Evaluation Criteria in Solid Tumors version 1.1; an Eastern Cooperative Oncology Group performance status score of 0 or 1; and adequate organ function. Patients were randomly assigned (1:1) via interactive response technology and stratified according to region, number of organs with metastases, and previous gastrectomy. Patients received zolbetuximab (800 mg/m2 loading dose followed by 600 mg/m2 every 3 weeks) plus mFOLFOX6 (every 2 weeks) or placebo plus mFOLFOX6. The primary endpoint was progression-free survival assessed by independent review committee in all randomly assigned patients. Safety was assessed in all treated patients. The study is registered with ClinicalTrials.gov, NCT03504397, and is closed to new participants. FINDINGS Between June 21, 2018, and April 1, 2022, 565 patients were randomly assigned to receive either zolbetuximab plus mFOLFOX6 (283 patients; the zolbetuximab group) or placebo plus mFOLFOX6 (282 patients; the placebo group). At least one dose of treatment was administered to 279 (99%) of 283 patients in the zolbetuximab group and 278 (99%) of 282 patients in the placebo group. In the zolbetuximab group, 176 (62%) patients were male and 107 (38%) were female. In the placebo group, 175 (62%) patients were male and 107 (38%) were female. The median follow-up duration for progression-free survival was 12·94 months in the zolbetuximab group versus 12·65 months in the placebo group. Zolbetuximab treatment showed a significant reduction in the risk of disease progression or death compared with placebo (hazard ratio [HR] 0·75, 95% CI 0·60-0·94; p=0·0066). The median progression-free survival was 10·61 months (95% CI 8·90-12·48) in the zolbetuximab group versus 8·67 months (8·21-10·28) in the placebo group. Zolbetuximab treatment also showed a significant reduction in the risk of death versus placebo (HR 0·75, 95% CI 0·60-0·94; p=0·0053). Treatment-emergent grade 3 or worse adverse events occurred in 242 (87%) of 279 patients in the zolbetuximab group versus 216 (78%) of 278 patients in the placebo group. The most common grade 3 or worse adverse events were nausea, vomiting, and decreased appetite. Treatment-related deaths occurred in five (2%) patients in the zolbetuximab group versus four (1%) patients in the placebo group. No new safety signals were identified. INTERPRETATION Targeting CLDN18.2 with zolbetuximab significantly prolonged progression-free survival and overall survival when combined with mFOLFOX6 versus placebo plus mFOLFOX6 in patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma. Zolbetuximab plus mFOLFOX6 might represent a new first-line treatment in these patients. FUNDING Astellas Pharma, Inc.

Abstract
PURPOSE To assess the ability of circulating tumor DNA (ctDNA)-based testing to identify patients with HER2 (encoded by ERBB2)-positive gastric/gastroesophageal adenocarcinoma (GEA) who progressed on or after trastuzumab-containing treatments were treated with combination therapy of anti-HER2 and anti-PD-1 agents. METHODS ctDNA analysis was performed retrospectively using plasma samples collected at study entry from 86 patients participating in the phase 1/2 CP-MGAH22-05 study (NCT02689284). RESULTS Objective response rate (ORR) was significantly higher in evaluable ERBB2 amplification-positive vs - negative patients based on ctDNA analysis at study entry (37% vs 6%, respectively; P = .00094). ORR was 23% across all patients who were evaluable for response. ERBB2 amplification was detected at study entry in 57% of patients (all HER2 positive at diagnosis), and detection was higher (88%) when HER2 status was determined by immunohistochemistry fewer than 6 months before study entry. ctDNA was detected in 98% (84/86) of patients tested at study entry. Codetected ERBB2-activating mutations were not associated with response. CONCLUSIONS Current ERBB2 status may be more effective than archival status at predicting clinical benefit from margetuximab plus pembrolizumab therapy. ctDNA testing for ERBB2 status prior to treatment will spare patients from repeat tissue biopsies, which may be reserved for reflex testing when ctDNA is not detected.

Abstract
BACKGROUND Advanced gastro-oesophageal cancer (AGOC) carries a poor prognosis. No standard of care treatment options are available after first and second-line therapies. Regorafenib is an oral multi-targeted tyrosine kinase inhibitor targeting angiogenic, stromal, and oncogenic receptor tyrosine kinases. Regorafenib 160 mg daily prolonged progression free survival compared to placebo (INTEGRATE, phase 2). Regorafenib 80 mg daily in combination with nivolumab 3 mg/kg showed promising objective response rates (REGONIVO). METHODS/DESIGN INTEGRATE II (INTEGRATE IIa and IIb) platform comprises two international phase III randomised controlled trials (RCT) with 2:1 randomisation in favor of experimental intervention. INTEGRATE IIa (double-blind) compares regorafenib 160 mg daily on days 1 to 21 of each 28-day cycle to placebo. INTEGRATE IIb (open label) compares REGONIVO, regorafenib 90 mg days 1 to 21 in combination with intravenous nivolumab 240 mg days 1 and 15 each 28-day cycle with investigator's choice of chemotherapy (control). Treatment continues until disease progression or intolerable adverse events as per protocol. Eligible participants include adults with AGOC who have failed two or more lines of treatment. Stratification is by location of tumour (INTEGRATE IIa only), geographic region, prior VEGF inhibitor and prior immunotherapy use (INTEGRATE IIb only). Primary endpoint is overall survival. Secondary endpoints are progression free survival, objective response rate, quality of life, and safety. Tertiary/correlative objectives include biomarker and pharmacokinetic evaluation. DISCUSSION INTEGRATE II provides a platform to evaluate the clinical utility of regorafenib alone, as well as regorafenib in combination with nivolumab in treatment of participants with refractory AGOC. TRIAL REGISTRATION INTEGRATE IIa prospectively registered 1 April 2016 Australia New Zealand Clinical Trial Registry: ACTRN12616000420448 (ClinicalTrials.gov NCT02773524). INTEGRATE IIb prospectively registered 10 May 2021 ClinicalTrials.gov: NCT04879368.

LBA292 Background: 1L treatment for pts with HER2−, mG/GEJ adenocarcinoma is typically chemotherapy and immunotherapy; an unmet need still exists. CLDN18.2 is expressed in normal gastric mucosa cells and retained in mG/GEJ tumor cells. In the FAST study, zolbetuximab, which targets CLDN18.2, prolonged survival of pts with LA unresectable or mG/GEJ adenocarcinoma when combined with chemotherapy. SPOTLIGHT (NCT03504397) is a phase 3 global, double-blind study comparing zolbetuximab + folinic acid, 5-FU, and oxaliplatin (mFOLFOX6) vs placebo + mFOLFOX6 as 1L treatment for pts with CLDN18.2+/ HER2−, LA unresectable or mG/GEJ adenocarcinoma. Methods: Previously untreated pts with CLDN18.2+ (moderate-to-strong membrane staining in ≥75% tumor cells by IHC)/HER2− LA unresectable or mG/GEJ adenocarcinoma were randomized 1:1 to zolbetuximab IV 800 mg/m2 (cycle [C] 1, day [D] 1) followed by 600 mg/m2 (C1D22, and every 3 weeks in later cycles) + mFOLFOX6 IV (D1, 15, 29) for four 42-day cycles vs placebo + mFOLFOX6; pts without PD continued for >4 cycles with zolbetuximab or placebo, + folinic acid and 5-FU at investigator’s discretion until PD or discontinuation criteria were met. The primary endpoint (EP) was PFS per RECIST v1.1 by IRC. Secondary EPs included OS, ORR, and safety. Differences in efficacy between treatment arms were tested by stratified log rank tests; OS was tested if PFS was significant. Results: Among 2735 pts screened, 565 pts were randomized 1:1 to zolbetuximab + mFOLFOX6 (N = 283) or placebo + mFOLFOX6 (N = 282). PFS was statistically significantly improved with zolbetuximab + mFOLFOX6 (median 10.61 vs 8.67 mo, HR 0.751, P=0.0066; Table). OS was also significantly improved (median 18.23 vs 15.54 mo, HR 0.750, P=0.0053, < 0.0135 as boundary; Table). ORR was similar between treatment arms. Most common TEAEs with zolbetuximab + mFOLFOX6 were nausea (82.4% vs 60.8% in zolbetuximab vs placebo arms), vomiting (67.4% vs 35.6%), and decreased appetite (47.0% vs 33.5%); the incidences of serious TEAEs were similar between both arms (44.8% vs 43.5%). Conclusions: Targeting CLDN18.2 with 1L zolbetuximab combined with mFOLFOX6 statistically significantly prolonged PFS and OS in pts with CLDN18.2+/ HER2−, LA unresectable or mG/GEJ adenocarcinoma. TEAEs were consistent with previous studies. Zolbetuximab + mFOLFOX6 may be a new option for these pts. Funding source: This study was funded by Astellas Pharma Inc.

Abstract
408 Background: The phase 3 PRODIGY study showed that neoadjuvant docetaxel, oxaliplatin and S-1 (DOS) chemotherapy, as part of perioperative chemotherapy, was effective and tolerable in Asian patients with resectable locally advanced gastric cancer (LAGC). The current study aimed to evaluate the efficacy and safety of neoadjuvant durvalumab plus DOS, which was followed by surgery and adjuvant durvalumab plus S-1 chemotherapy in patients with resectable LAGC. Methods: In this single-center, open-label, phase II study, patients with locally advanced gastric or gastroesophageal junction cancer (i.e., cT2/3N+ or cT4Nany) were enrolled. In patients with proficient mismatch repair protein (pMMR) tumors (main arm), 3 cycles of neoadjuvant durvalumab plus DOS were administered every 3 weeks, which was followed by surgery and adjuvant S-1 plus durvalumab administered every 6 weeks for 12 months. The primary endpoints were the rate of pathologic complete regression (pCR) and the safety. For an exploratory purpose, patients with deficient mismatch repair protein tumors (exploratory arm) were treated with 3 cycles of neoadjuvant durvalumab and tremelimumab every 4 weeks followed by surgery and adjuvant durvalumab administered every 4 weeks for 12 months. At this interim analysis, we report the results of patients with pMMR. Results: As of SEP 2022, 40 subjects with pMMR were enrolled and received ≥ 1 dose of neoadjuvant treatment. Thirty-five subjects completed 3 cycles of neoadjuvant treatment, and 31 received surgery as of the data cut-off. Among 31 patients who received surgery, a pCR was confirmed in 9 (29.0%), meeting the primary efficacy endpoint (8 pCR out of 40) early. Among those who received 3 cycles of neoadjuvant treatment, 3 (8.6%) experienced the predefined unacceptable severe toxicities during the neoadjuvant treatment: febrile neutropenia (n=2) and G4 neutropenia persisted for ≥ 7 days (n=1). Conclusions: The current study met its primary efficacy endpoint and is expected to meet the primary safety endpoint (<20%). Neoadjuvant durvalumab plus DOS followed by surgery and adjuvant durvalumab plus S-1 chemotherapy deserves to be investigated in a phase 3 trial in Asian patients with LAGC.

Abstract
461 Background: In localized gastric cancer (GC), deficient mismatch repair (dMMR) tumors reportedly have a favorable prognosis. However, a potentially detrimental effect of the dMMR status was suggested in patients treated with adjuvant chemotherapy. It remains unclear whether the mismatch repair (MMR) status can impact clinical outcomes in patients with metastatic GC (mGC) receiving palliative chemotherapy. We examined the impact of the MMR status on survival outcomes of patients with HER2-negative mGC receiving first-line fluoropyrimidine plus platinum (FP) chemotherapy. Methods: We reviewed patients with histologically confirmed metastatic, recurrent, or locally advanced unresectable adenocarcinoma of the stomach or gastroesophageal junction receiving first-line FP chemotherapy between January 2015 and August 2018 at Asan Medical Center, Korea. MMR status was correlated with clinical characteristics and survival outcomes for patients with available MMR immunohistochemistry results. Results: Of 895 patients, we analyzed 543 with available MMR protein expression results, and dMMR was detected in 4.4% (n=24). Patients with dMMR exhibited a significantly higher median age than those with proficient MMR (pMMR) (64 vs. 58 years, p=0.044). No signet ring cell carcinoma (SRCC) was detected among dMMR tumors, whereas SRCC was found in 17.5% of pMMR tumors. Based on our prognostic model (Koo DH et al, 2011), only 4.2% of patients with dMMR were classified as the poor-risk group (vs. 16.8% of patients with pMMR, p=0.097). No significant difference in progression-free survival (PFS) was noted between patients with dMMR and pMMR tumors (median, 5.6 vs. 5.8 months, p=0.266). Patients with dMMR tumors tended to have better overall survival than those with pMMR tumors; this difference was not statistically significant (median, 17.9 vs. 12.2 months, p=0.183). In the good-risk subgroup, patients with dMMR tumors had a significantly worse PFS than those with pMMR tumors (median, 5.6 vs. 9.2 months, p=0.009); multivariate analysis revealed that MMR status was an independent factor for poor PFS in this subgroup. Conclusions: Survival outcomes of dMMR mGC did not differ from pMMR in patients who received first-line FP chemotherapy. However, in the good-risk subgroup, patients with dMMR tumors had a significantly shorter PFS than those with pMMR, suggesting a potentially reduced efficacy of cytotoxic chemotherapy in these patients.

Abstract
347 Background: Zanidatamab (zani) is an anti-HER2 bispecific antibody against ECD4 and ECD2 with demonstrated activity and tolerability in a range of HER2-expressing cancers. This Phase (Ph) 2 study (NCT03929666) evaluates zani in combination with chemotherapy (chemo) as first-line treatment for patients (pts) with advanced HER2-expressing mGEA. Methods: Eligible pts for this ongoing, open-label study had not received any prior systemic therapy for mGEA. Pts received zani + physician’s choice of multi-agent chemo (mFOLFOX6, CAPOX, or FP). Antidiarrheal prophylaxis for cycle 1 was added after the first 25 pts were treated. Following demonstration of tolerability of the regimens in an initial safety cohort, the primary study objective was to evaluate antitumor activity. Results: Pts were enrolled between Aug 29, 2019 and Feb 18, 2022 with a data cutoff of July 28, 2022 (N=46 pts; zani + mFOLFOX6 [24], zani + CAPOX [20], or zani + FP [2]). Median age was 58 yrs; 85% male; 42 pts (91%) had HER2+ tumors (IHC 3+ or 2+ with ISH-positivity) based on central testing. Median duration of follow-up among all 46 pts was 21.5 months (mo) and 20 pts (43%) remain on treatment. In 38 response-evaluable pts with HER2+ tumors, confirmed objective response rate (cORR) was 79% (95% CI: 63-90%) and disease control rate was 92% (95% CI: 79-98%); 3 pts achieved complete response. Median duration of response (DOR) was 20.4 mo (95% CI: 6.8-not estimable [NE]), with 57% (17/30) pts having an ongoing response at data cut-off (1 pt has ongoing response >29 months). In all 42 pts with HER2+ tumors, median progression-free survival (PFS) was 12.5 mo (95% CI: 7.1-NE) and median overall survival (OS) was not yet reached. Survival rate at 18 mo was estimated to be 87.3%. The most common (≥25% pts) treatment-related (zani and/or chemo) adverse events (TRAE) in all pts were diarrhea, nausea, peripheral sensory neuropathy, decreased appetite, fatigue, vomiting, and hypokalemia. Diarrhea was the most common Gr3+ TRAE, lasting a median (interquartile range) of 3 (2-5) days, with the majority of events occurring in cycle 1; incidence of all Gr3+ events was 56% in 25 pts who did not receive prophylaxis and 14% in 21 pts who did. There were no treatment-related deaths. Conclusions: In pts with HER2+ mGEA, zani + chemo is a highly active treatment regimen with a manageable safety profile. This maturing data set demonstrates durable disease control with encouraging cORR, DOR, PFS and OS results. A global Ph 3 study (HERIZON-GEA-01; NCT05152147) evaluating zani in combination with physician’s choice of standard chemo with or without the PD-1 inhibitor, tislelizumab, for first-line treatment of advanced HER2+ mGEA is currently enrolling.

Abstract
401 Background: Currently, ramucirumab plus paclitaxel is the standard second-line chemotherapy in metastatic gastric cancer (mGC), however, its efficacy is very limited. MSI, PD-L1 (CD274), and EBV have been suggested as predictive biomarkers for immune checkpoint inhibitors in mGC. This study was conducted to evaluate efficacy and safety of the combination of durvalumab, tremelimumab, and paclitaxel as a second-line chemotherapy in mGC with potential biomarkers for immune checkpoint inhibitors. Methods: The combination of durvalumab, tremelimumab, and paclitaxel consisted of 1500 mg of i.v. durvalumab on day 1, every 4 weeks for 13 cycles, 75 mg of i.v. tremelimumab on day 1 every 4 weeks for 4 cycles, and 60 mg/m2 of i.v. paclitaxel on days 1, 8, and 15, every 4 weeks until disease progression or unacceptable toxicities. Patients (pts) with MSI-high mGC, EBV-positive mGC, or mGC with CD274 amplification, mutations of mismatch repair or POL gene, or tumor mutation burden (TMB) >5/Mb were included in second-line setting. Results: Forty-eight pts were enrolled. Overall response rate (ORR) was 52.1% with complete response in 4 (8.3%) pts, partial response in 21 (43.8%), stable disease in 14 (29.2%), and progressive disease in 8 (16.7%), and with response not evaluable in 1 (2.0%). With a median follow-up of 18.0 months (range, 7.1-39.4), the median progression-free survival (PFS) and overall survival (OS) were 5.3 months (95% CI, 3.7-6.9) and 13.1 months (95% CI, 5.2-21.0 ), respectively. Compared to mGC with other genetic alterations (n=25), mGC with TMB >20/Mb or MSI-high mGC (n=23) tended to have a higher ORR (56.5% vs 48%), and a prolonged PFS (median 7.2 vs 4.5 months; 44.0 vs 20.8% at 1 year). The combination chemotherapy was generally well tolerable; treatment-related grade 3 or 4 adverse events with frequency >5% included only neutropenia (10.4%) and anemia (8.3%), and there was no treatment-related death. Conclusions: The combination chemotherapy of durvalumab, tremelimumab, and paclitaxel showed encouraging efficacy, especially in mGC with TMB >20/Mb or MSI-high mGC, as a second-line chemotherapy with manageable toxicities in biomarker-selected mGC. Clinical trial information: NCT03751761 .

Abstract
431 Background: Benefit of perioperative or postoperative chemotherapy for resectable locally advanced gastric cancer (LAGC) with DNA mismatch repair (MMR) deficiency is controversial due to concerns about the potential detrimental effect of perioperative chemotherapy. In this sub-analysis of the phase 3 PRODIGY trial, we evaluated the association between the MMR status and outcomes of resectable LAGC treated with perioperative or postoperative chemotherapy. Methods: Among 249 patients with resectable LAGC enrolled in the PRODIGY trial treated with either perioperative chemotherapy (preoperative docetaxel, oxaliplatin, and S-1 [DOS] followed by surgery and postoperative S-1; CSC arm) or surgery and postoperative S-1 (SC arm) at Asan Medical Center, those in the full analysis set with available tissue for MMR status assessment by immunohistochemistry were included in this study. Progression-free survival (PFS) was compared according to the MMR status and treatment arm. In the CSC arm, the pathologic complete response (pCR) rate was compared according to the MMR status. Results: A total of 231 patients (CSC arm, n = 108; SC arm, n = 123) were included in the study (median age, 58 years [range, 27–75]). Twenty-one patients (CSC arm, n = 8 [7.4%]; SC arm, n = 13 [10.6%]) had deficient MMR (D-MMR) tumors while the rest had proficient MMR (P-MMR) tumors. There was no significant difference in the baseline characteristics including the clinical stage according to the MMR status. Among patients with P-MMR tumors, PFS tended to be superior in the CSC arm than in the SC arm (hazard ratio [HR] 0.67 [95% confidence interval (CI) 0.44–1.03]; log-rank P = 0.07). Among patients with D-MMR tumors, the PFS of the CSC arm was not inferior to that of the SC arm (HR 0.50 [95% CI 0.10–2.60]; log-rank P = 0.41). In the CSC arm, the pCR rate was 5.0% (5/100) and 12.5% (1/8) in patients with P-MMR and D-MMR tumors, respectively. Conclusions: In this sub-analysis of the PRODIGY trial, the PFS of the CSC arm was not inferior to that of the SC arm among patients with D-MMR LAGC. Among patients who received preoperative DOS, the pCR rate was not lower in patients with D-MMR tumors compared with those with P-MMR tumors. Perioperative chemotherapy consisting of preoperative DOS followed by surgery and postoperative S-1 may be recommended for patients with LAGC regardless of the MMR status.

Abstract
397784 Background: Ripretinib, a switch-control tyrosine kinase inhibitor (TKI), is indicated for patients (pts) with gastrointestinal stromal tumor (GIST) who received prior treatment with ≥3 TKIs, including imatinib. Sunitinib is approved for advanced GIST after imatinib failure. Circulating tumor DNA (ctDNA) analysis may provide insight into the efficacy of these agents in second-line advanced GIST. Here, we present exploratory baseline ctDNA results from INTRIGUE. Methods: INTRIGUE is an open-label, phase 3 study that enrolled adult pts with advanced GIST who progressed on or had intolerance to imatinib (NCT03673501). Randomization was 1:1 to ripretinib 150 mg once daily (QD) or sunitinib 50 mg QD (4 wks on/2 wks off). Baseline peripheral whole blood was analyzed by Guardant360, a 74-gene ctDNA next-generation sequencing (NGS)-based assay. Only KIT mutations are reported here. Results: Of 453 pts in the overall intent-to-treat (ITT) population, 362 (80%) samples were analyzed. ctDNA was detected in 280/362 (77%), with KIT mutations detected in 213/280 (76%). Common resistance mutations were in the KIT activation loop (AL; exons 17/18; 89/213, 42%) and ATP-binding pocket (ATP-BP; exons 13/14; 81/213, 38%). Efficacy in pts with detectable ctDNA in the KIT exon 11 and overall ITT populations was consistent with the primary analysis based on tumor data used for randomization. Pts with KIT exon 11 + 17/18 (−9/13/14) mutations had superior progression-free survival (PFS), objective response rate (ORR), and overall survival (OS) with ripretinib vs sunitinib, whereas pts with exon 11 + 13/14 (−9/17/18) mutations had better PFS, ORR, and OS with sunitinib vs ripretinib (Table). Subgroup safety profiles were consistent with the primary analysis. Conclusions: While KIT ATP-BP mutations predicted clinical benefit from sunitinib vs ripretinib, pts harboring resistance mutations in the KIT AL derived meaningful clinical benefit from ripretinib but not sunitinib. This study demonstrates the value of ctDNA NGS-based sequencing of the complex landscape of KIT mutations to predict the clinical benefit of ripretinib or sunitinib as second-line therapy in pts with advanced GIST. Clinical trial information: NCT03673501 . [Table: see text]

Abstract
BACKGROUND Dual-targeted anti-HER2 therapy significantly improves outcomes in HER2-positive breast cancer and could be beneficial in other HER2-positive cancers. JACOB's end-of study analyses aimed to evaluate the long-term efficacy and safety of pertuzumab plus trastuzumab and chemotherapy for previously untreated HER2-positive metastatic gastric or gastroesophageal junction cancer. METHODS Eligible patients were randomized 1:1 to pertuzumab/placebo plus trastuzumab and chemotherapy every 3 weeks. PRIMARY ENDPOINT overall survival (OS). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), duration of response (DoR), and safety. RESULTS The intention-to-treat population comprised 388 patients in the pertuzumab arm and 392 in the placebo arm. The safety population comprised 385 and 388 patients, respectively. Median follow-up was ≥ 44.4 months. Median OS was increased by 3.9 months (hazard ratio 0.85 [95% confidence intervals, 0.72-0.99]) and median PFS by 1.3 months (hazard ratio 0.73 [95% confidence intervals, 0.62-0.85]) in the pertuzumab vs. the placebo arm. ORR was numerically higher (57.0% vs. 48.6%) and median DoR 1.8 months longer with pertuzumab treatment. There was a trend for more favorable hazard ratios in certain subgroups related to HER2 amplification/overexpression. Safety was comparable between arms, except for serious and grade 3-5 adverse events, and any-grade diarrhea, which were more frequent with pertuzumab. CONCLUSIONS JACOB did not meet its primary endpoint. Nonetheless, the study continues to demonstrate some, albeit limited, evidence of treatment activity and an acceptable safety profile for pertuzumab plus trastuzumab and chemotherapy in previously untreated HER2-positive metastatic gastric or gastroesophageal junction cancer after long-term follow-up.

Abstract
BACKGROUND In this randomized phase II study, we evaluated the efficacy and safety of sorafenib in combination with capecitabine and cisplatin (XP) as first-line chemotherapy in advanced gastric cancer. PATIENTS AND METHODS Patients with metastatic gastric or gastroesophageal junction adenocarcinoma were randomized (1:1) to receive either sorafenib plus XP (S + XP) or XP alone. In cases of disease progression in the XP arm, crossover to sorafenib alone was allowed. The primary endpoint was progression-free survival (PFS). The secondary endpoints included overall survival (OS), response rates, safety profiles, and biomarkers, and the response rates and PFS with secondline sorafenib alone after progression in the XP arm. RESULTS Between Jan 2011 and Feb 2013, a total of 195 patients were accrued (97 in the S + XP arm and 98 in the XP alone arm). The overall response rate was 54% with S + XP, and 52% with XP alone (p = 0.83). With a median follow-up of 12.6 months (range, 0.1-29.2), the median PFS assessed by independent review was 5.6 months in the S + XP arm and 5.3 months in the XP arm (hazard ratio [HR] 0.92, 95% confidence interval [CI] 0.67-1.27, p = 0.61). Overall survival was not different between the two arms (median 11.7 vs. 10.8 months; HR 0.93, 95% CI 0.65-1.31, p = 0.66). Frequencies of grade 3/4 toxicities were similar between the S + XP and XP alone arms, except for neutropenia (21% vs. 37%), anorexia (0% vs. 5%), and hand-foot skin reaction (7% vs. 1%). Among 51 patients who crossed over to sorafenib alone after disease progression in the XP arm, there was no objective response and their median PFS was 1.3 months (95% CI, 1.2-1.7). CONCLUSION The addition of sorafenib to XP chemotherapy was safe but not more effective than XP alone for first-line treatment of metastatic gastric cancer.

Abstract
PURPOSE Sunitinib, a multitargeted tyrosine kinase inhibitor (TKI), is approved for advanced gastrointestinal stromal tumor (GIST) after imatinib failure. Ripretinib is a switch-control TKI approved for advanced GIST after prior treatment with three or more TKIs, including imatinib. We compared efficacy and safety of ripretinib versus sunitinib in patients with advanced GIST who were previously treated with imatinib (INTRIGUE, ClinicalTrials.gov identifier: NCT03673501). PATIENTS AND METHODS Random assignment was 1:1 to once-daily ripretinib 150 mg or once-daily sunitinib 50 mg (4 weeks on/2 weeks off) and stratified by KIT/platelet-derived growth factor α mutation and imatinib intolerance. The primary end point was progression-free survival (PFS) by independent radiologic review using modified Response Evaluation Criteria in Solid Tumors version 1.1. Secondary end points included objective response rate by independent radiologic review, safety, and patient-reported outcome measures. RESULTS Overall, 453 patients were randomly assigned to ripretinib (intention-to-treat [ITT], n = 226; KIT exon 11 ITT, n = 163) or sunitinib (ITT, n = 227; KIT exon 11 ITT, n = 164). Median PFS for ripretinib and sunitinib (KIT exon 11 ITT) was 8.3 and 7.0 months, respectively (hazard ratio, 0.88; 95% CI, 0.66 to 1.16; P = .36); median PFS (ITT) was 8.0 and 8.3 months, respectively (hazard ratio, 1.05; 95% CI, 0.82 to 1.33; nominal P = .72). Neither was statistically significant. Objective response rate was higher for ripretinib versus sunitinib in the KIT exon 11 ITT population (23.9% v 14.6%, nominal P = .03). Ripretinib was associated with a more favorable safety profile, fewer grade 3/4 treatment-emergent adverse events (41.3% v 65.6%, nominal P < .0001), and better scores on patient-reported outcome measures of tolerability. CONCLUSION Ripretinib was not superior to sunitinib in terms of PFS. However, meaningful clinical activity, fewer grade 3/4 treatment-emergent adverse events, and improved tolerability were observed with ripretinib.

Abstract
Importance Approval by the US Food and Drug Administration of immune checkpoint inhibition (ICI) for advanced gastroesophageal cancer (aGEC) irrespective of PD-L1 status has generated controversy. Exploratory analyses from individual trials indicate a lack of meaningful benefit from ICI in patients with absent or low PD-L1 expression; however, analysis of a single variable while ignoring others may not consider the instability inherent in exploratory analyses. Objective To systematically examine the predictive value of tissue-based PD-L1 status compared with that of other variables for ICI benefit in aGEC to assess its stability. Data Sources MEDLINE, Embase, Scopus, Web of Science, Cochrane Central Register (2000-2022). Study Selection, Data Extraction, and Synthesis Randomized clinical trials (RCTs) were included of adults with aGEC (adenocarcinoma [AC] or squamous cell carcinoma [SCC]) randomized to anti-PD-1 or PD-L1-containing treatment vs standard of care (SOC). Study screening, data abstraction, and bias assessment were completed independently by 2 reviewers. Of 5752 records screened, 26 were assessed for eligibility; 17 trials were included in the analysis. Main Outcomes and Measures The prespecified primary end point was overall survival. The mean hazard ratio (HR) for ICI vs SOC was calculated (random-effects model). Predictive values were quantified by calculating the ratio of mean HRs between 2 levels of each variable. Results In all, 17 RCTs (9 first line, 8 after first line) at low risk of bias and 14 predictive variables were included, totaling 11 166 participants (5067 with SCC, 6099 with ACC; 77.6% were male and 22.4% were female; 59.5% of patients were younger than 65 years, 40.5% were 65 years or older). Among patients with SCCs, PD-L1 tumor proportion score (TPS) was the strongest predictor of ICI benefit (HR, 0.60 [95% CI, 0.53-0.68] for high TPS; and HR, 0.84 [95% CI, 0.75-0.95] for low TPS), yielding a predictive value of 41.0% favoring high TPS (vs ≤16.0% for other variables). Among patients with AC, PD-L1 combined positive score (CPS) was the strongest predictor (after microsatellite instability high status) of ICI benefit (HR, 0.73 [95% CI, 0.66-0.81] for high CPS; and HR, 0.95 [95% CI, 0.84-1.07] for low CPS), yielding a predictive value of 29.4% favoring CPS-high (vs ≤12.9% for other variables). Head-to-head analyses of trials containing both levels of a variable and/or having similar design generally yielded consistent results. Conclusions and Relevance Tissue-based PD-L1 expression, more than any variable other than microsatellite instability-high, identified varying degrees of benefit from ICI-containing therapy vs SOC among patients with aGEC in 17 RCTs.

Abstract
BACKGROUND The GASTHER1 study showed that re-evaluation of HER2 status rescued 8% of HER2-positive gastric cancer (GC) patients with initially HER2-negative GC. Since rescued HER2 positivity represents HER2 heterogeneity, we aimed to investigate this in a larger cohort with longer follow-up duration. METHODS Data of 153 HER2-positive advanced GC patients who received first-line trastuzumab-based chemotherapy were analyzed. Repeat endoscopic biopsy was performed in patients with initially HER2-negative GC. Survival outcomes were analyzed according to the immunohistochemistry (IHC) score (IHC 2+ /in situ hybridization [ISH] + vs IHC 3+), HER2 status (initially vs rescued HER2 positive), and H-score. RESULTS IHC 2+ /ISH + patients showed worse progression-free survival (PFS) and overall survival (OS) than those with IHC 3+ (p < 0.05). Rescued HER2-positive patients showed worse PFS and OS than initially HER2-positive patients (p < 0.05). Although survival outcomes were comparable according to HER2 status in IHC 2+ /ISH + patients, initially HER2-positive patients showed more favorable PFS and OS than rescued HER2-positive patients (p < 0.05) among those with IHC 3+ . Among the subgroups determined by HER2 status and IHC score, the initially IHC 3+ subgroup had the highest H-score. The low H-score group (H-score ≤ 210) had significantly worse survival outcomes than the high H-score group (H-score > 210) (p < 0.05). An H-score of ≤ 210 was independently associated with shorter OS (HR = 1.54, 95% CI 1.02-2.31, p = 0.04). CONCLUSIONS Rescued HER2-positive patients showed worse clinical outcomes than initially HER2-positive patients, especially those with IHC 3+ . This finding highlights the impact of HER2 heterogeneity, which can be quantified indirectly as an H-score.

Abstract
Abstract
Background: The ecto-ATPase CD39 is the rate-limiting enzyme in the adenosine pathway that plays an important immune regulatory role. Preclinically, inhibition of CD39 by TTX-030, a first-in-class fully human anti-CD39 antibody, reversed immunosuppression by maintaining high levels of immune-stimulatory extracellular ATP while reducing suppressive adenosine. The addition of nivolumab to chemotherapy has recently become the standard of care of 1st-line (1L) treatment of locally advanced or metastatic (LA/M) gastric cancer but further improvements are needed.
Methods: An expansion cohort of Study TTX-030-002 (ongoing, US and South Korea) is evaluating the safety and efficacy of the combination of TTX-030, budigalimab (anti-PD-1) and FOLFOX for the 1L treatment of patients (pts) with LA/M HER2− gastric/GEJ adenocarcinoma. The primary objective was to assess safety and tolerability. Secondary endpoints included ORR by RECIST/iRECIST, and PFS. Correlative studies included the analysis of intratumoral expression of CD39 and PD-L1.
Results: Forty-four pts were enrolled with the median age [range] of 61 [30−81] years, 41% were female, and 57% were Asian. Pts had an ECOG of 0 (39%) or 1 (61%), 70% had gastric adenocarcinoma, 30% had GEJ adenocarcinoma. As of the safety data cutoff (Nov 19, 2021), 39 pts (89%) experienced at least 1 treatment-emergent AE (any Grade, regardless of relatedness). Twenty-one pts (48%) experienced at least 1 AE considered related to TTX-030 (any Grade); five (11%) experienced a Grade 3/4 AE considered related to TTX-030. There were no Grade 5 TEAEs. Eleven pts (25%) had experienced SAEs; none were considered related to TTX-030. The most common AEs by preferred term (any Grade, regardless of relatedness) in ≥10 pts were nausea (52%), neutrophil count decreased (39%), decreased appetite (30%), diarrhea (25%), and fatigue (23%). The most common Grade ≥3 AEs (regardless of relatedness) in ≥2 pts were neutrophil count decreased (27%), febrile neutropenia (5%), hypokalemia (5%). As of the efficacy data cutoff (Dec 2, 2021), the median time [range] on study was 139 [8−375] days. Among 38 efficacy evaluable pts, 23 pts experienced PR or better as best response (PR: n=21; CR: n=2; ORR=61%), 12 experienced SD, and 3 had PD. Thirty-six of the 38 efficacy-evaluable patients had known PD-L1 Combined Positive Score (CPS); response rates were 4/10 (CPS <1), 8/10 (CPS ≥1 and <5), and 11/16 (CPS ≥ 5).
Conclusions: Preliminary results indicate that the combination of TTX-030, budigalimab and FOLFOX exhibited promising efficacy as 1L treatment of LA/M gastric/GEJ cancer regardless of CPS status and has a manageable safety profile without evidence of excessive toxicities. To our knowledge, this represents the first report of an anti-CD39 antibody in combination with chemo-immunotherapy in gastric cancer. Updated clinical and biomarker data will be included in the final presentation.

Abstract
Three years of adjuvant imatinib is the current standard for patients with high-risk gastrointestinal stromal tumors (GIST). We aimed to investigate the safety and efficacy profiles of 3-year imatinib, focusing on the prognostic value of various factors. In this registry-based study, 222 patients with high-risk GIST who underwent surgical resection followed by 3 years of adjuvant imatinib between 2010 and 2018 were included. The imatinib dose was reduced in 39 (17.6%), and 13 (5.9%) discontinued imatinib due to toxicity. With a median follow-up duration of 65.7 months, 5-year recurrence-free survival (RFS) and overall survival (OS) were 73.2% and 93.9%, respectively. Tumor rupture, tumor size of > 10 cm, mitotic index of > 10/50 high power fields (HPF) were independent factors for short RFS. Patient subgroups stratified by the risk factors showed distinct RFS (P < 0.001): patients without the above risk factors or those with only a tumor size of >10 cm showed favorable RFS (5-year RFS 83.8% and 92.3%, respectively), whereas those with tumor rupture or those with tumor size of > 10 cm and mitotic index of >10/50 HPF showed prominently poor RFS (5-year RFS of 54.8% and 47.9%, respectively). Three years of adjuvant imatinib treatment was generally tolerable and effective, which were consistent with the clinical outcomes of previous reports. The presence of tumor rupture, large tumor, and high mitotic count was independently associated with poor RFS. Based on these risk factors, different management strategies, such as different durations of adjuvant imatinib, deserve further investigation. This article is protected by copyright.

Abstract
BACKGROUND Deregulation of FGF19-FGFR4 signaling is found in several cancers, including hepatocellular carcinoma (HCC), nominating it for therapeutic targeting. FGF401 is a potent, selective FGFR4 inhibitor with antitumor activity in preclinical models. This study was designed to determine the recommended phase 2 dose (RP2D), characterize PK/PD, and evaluate the safety and efficacy of FGF401 alone and combined with the anti-PD-1 antibody, spartalizumab. METHODS Patients with HCC or other FGFR4/KLB expressing tumors were enrolled. Dose-escalation was guided by a Bayesian model. Phase 2 dose-expansion enrolled patients with HCC from Asian countries (group1), non-Asian countries (group2), and patients with other solid tumors expressing FGFR4 and KLB (group3). FGF401 and spartalizumab combination was evaluated in patients with HCC. RESULTS Seventy-four patients were treated in the phase I with single-agent FGF401 at 50 to 150 mg. FGF401 displayed favorable PK characteristics and no food effect when dosed with low-fat meals. The RP2D was established as 120 mg qd. Six of 70 patients experienced grade 3 dose-limiting toxicities: increase in transaminases (n = 4) or blood bilirubin (n = 2). In phase 2, 30 patients in group 1, 36 in group 2, and 20 in group 3 received FGF401. In total, 8 patients experienced objective responses (1 CR, 7 PR; 4 each in phase I and phase II, respectively). Frequent adverse events (AEs) were diarrhea (73.8%), increased AST (47.5%), and ALT (43.8%). Increase in levels of C4, total bile acid, and circulating FGF19, confirmed effective FGFR4 inhibition. Twelve patients received FGF401 plus spartalizumab. RP2D was established as FGF401 120 mg qd and spartalizumab 300 mg Q3W; 2 patients reported PR. CONCLUSIONS At biologically active doses, FGF401 alone or combined with spartalizumab was safe in patients with FGFR4/KLB-positive tumors including HCC. Preliminary clinical efficacy was observed. Further clinical evaluation of FGF401 using a refined biomarker strategy is warranted. TRIAL REGISTRATION NCT02325739 .

Abstract
TPS4165 Background: Fibroblast growth factor receptor 2b (FGFR2b) is overexpressed in approximately 30% of non-human epidermal growth factor receptor 2 (non-HER2) positive gastric cancer (Wainberg, 2021). Bemarituzumab is a first-in-class monoclonal antibody that specifically blocks FGFR2b, inhibiting downstream tumor proliferation and enhancing antibody dependent cellular cytotoxicity (Catenacci, 2020; Xiang, 2021). In the phase 2 FIGHT study (Wainberg, 2021; Catenacci, 2021), progression-free survival (PFS) was improved (HR, 0.68; 95% CI, 0.44-1.04; p = 0.07) and a 5.7 month longer median overall survival (OS) was observed (19.2 months vs 13.5 months; HR, 0.60; 95% CI, 0.38-0.94) with bemarituzumab + mFOLFOX6 vs placebo + mFOLFOX6. Preclinical studies indicate that bemarituzumab modulates the tumor microenvironment to sensitize tumors to anti-PD1 monoclonal antibodies (Powers, 2016; Xiang, 2021) providing rationale for combination with nivolumab. Methods: FORTITUDE-102 (NCT05111626) is a phase 1b/3 study in patients (pts) with unresectable locally advanced or metastatic gastric or GEJ adenocarcinoma not amenable to curative therapy. Part 1 is an open-label safety lead-in; Part 2 is a double-blind, placebo-controlled study to evaluate efficacy and safety. Approximately 702 pts ≥18 years will be enrolled (Part 1, ̃20; Part 2, ̃682). Key eligibility criteria include Eastern Cooperative Oncology Group performance status 0-1, evaluable disease per RECIST v1.1, adequate hematologic and organ function, and no contraindication to receive mFOLFOX6 chemotherapy or nivolumab; for part 2, IHC-confirmed FGFR2b overexpression by central testing is required and no prior treatment for metastatic or unresectable disease allowed except 1 dose of mFOLFOX6 ± nivolumab. Key exclusion criteria include positive HER2 status and untreated or symptomatic CNS metastasis and leptomeningeal disease. Pts on bemarituzumab will receive 15 mg/kg every 2 weeks (Q2W) with an additional 7.5 mg/kg dose on cycle 1 day 8. mFOLFOX6 + nivolumab will be at a fixed dose Q2W. The dose-limiting toxicity (DLT) period is 28 days; observed safety data will influence additional enrollment to Part 1, de-escalation of bemarituzumab, or the recommended phase 3 dose (RP3D). For Part 1, primary endpoints are DLTs and adverse events; secondary endpoints include OS, PFS, and objective response (OR). For Part 2, pts will be randomized 1:1 to mFOLFOX6 + nivolumab Q2W plus either bemarituzumab at RP3D or placebo. Primary endpoint for Part 2 is OS; secondary endpoints include PFS, OR, and safety. The concurrent phase 3 FORTITUDE-101 study (NCT05052801) will evaluate bemarituzumab + mFOLFOX6 vs placebo + mFOLFOX6. Clinical trial information: NCT05111626.

Abstract
11538 Background: Resumption of imatinib is one of the available therapeutic options for patients with gastrointestinal stromal tumors (GIST) refractory to tyrosine kinase inhibitors (TKIs). Intermittent dosing of imatinib was suggested to delay outgrow of the imatinib-resistant clones in a preclinical study. Methods: A randomized phase 2 study was performed to evaluate the efficacy and safety of continuous or intermittent schedule of imatinib in GIST patients whose disease had progressed to at least imatinib and sunitinib. Patients were randomly assigned (1:1) to the intermittent dosing group that received 400mg daily imatinib based on a 1 week-on and 1 week-off schedule or the continuous dosing group that received imatinib 400mg daily without drug holiday. Disease control rate (DCR) rate at 12 weeks was the primary endpoint. Plasma samples were collected for circulating tumor DNA analysis at baseline, at 3 months of continuous or intermittent imatinib treatment and at the time of progressive disease. Results: Fifty patients received at least one dose of imatinib and were included in the full analysis set. Most patients (n = 46) had received prior regorafenib. DCR rate at 12 weeks was 34.8% and 43.5% in the continuous and intermittent groups, respectively. Median progression-free survival was 1.68 months and 1.57 months in the continuous and intermittent groups, respectively. The frequency of any grade anorexia, dysphagia, diarrhea, decreased neutrophil was lower in the intermittent group, whereas that of abdominal pain was higher in the intermittent group. Two patients in the continuous imatinib group underwent dose modification, and there was no patient who discontinued the study treatment because of adverse events related to study treatment. Conclusions: We confirmed that imatinib re-challenge was effective in TKI-refractory GIST patients. Intermittent dosing schedule may also be a clinically feasible treatment option for imatinib resumption in TKI-refractory GIST patients. Clinical trial information: NCT02712112.

Abstract
101 Background: The genotype of primary mutations predicts imatinib response in untreated metastatic GIST. However, the sequence of salvage treatments in metastatic GIST is based solely on the chronological order of registration trials. ctDNA sequencing offers a powerful diagnostic tool to detect resistance mutations in GIST but has not been shown to correlate with outcomes in clinical trials of pretreated patients (pts). We analyzed ctDNA samples collected at baseline in the phase III VOYAGER trial (NCT03465722) to describe the landscape of KIT alterations and its association with outcomes of pts treated with avapritinib or regorafenib. Methods: In VOYAGER, 476 pts with advanced KIT-mutant GIST were randomly assigned to avapritinib (240 pts) or regorafenib (236 pts) in 3rd-4th line. Baseline plasma was collected and ctDNA analyzed with the Guardant 360 (G360), 74-gene panel. KIT molecular subgroups were determined and correlated with outcomes. PDGFRA-mutant GISTs were excluded from outcomes analysis. Results: Baseline ctDNA analysis was performed in 386/476 pts (81%). ctDNA was detected in 333 pts (86%), with 250 and 18 pts showing at least one KIT (75%) or PDGFRA (5%) variant, respectively. KIT primary mutations were detected in 71% pts (exon 11, 56%; exon 9, 14%; exon 13, 1%) and KIT secondary mutations in 55% of pts. Activation loop (AL, exons 17 and 18) was more commonly affected (44%) than the ATP-binding pocket (ABP, exons 13 and 14; 23%). Among KIT-mutant tumors, multiple KIT mutations were commonly detected within individual tumors (mean, 2.56; range, 1-14). Notably, 17% of pts had > 3 mutations (mean, 6.07; range, 4 to 14). Median PFS and OS were shorter for patients whose ctDNA was positive for V654A or T670I (ABP hot spots) when treated with avapritinib vs. regorafenib: mPFS, 1.9 mo vs. 7.4 mo; log-rank p <.001; mOS, 8.3 mo vs. 11.7 mo; log rank p =.0651. mPFS was shorter for patients with ctDNA positive for KIT exon 17 mutation if concurrently KIT V654A/T670I was absent when treated with avapritinib, with no difference in OS: mPFS, 4.7 mo vs. 6.7 mo; log-rank p =.03; mOS, 19.2 mo vs. NR; log-rank p =.628. mPFS on avapritinib was longer when ABP mutations were absent when compared to those with ABP present (5.6 vs. 1.9 mo; log-rank p <.001). There were no differences considering AL mutations vs. no AL mutations (3.8 vs. 3.9 mo; log-rank p =.622) when treated with avapritinib. Regorafenib showed similar activity regardless of KIT mutational status and the location of KIT mutation. Conclusions: Hybrid capture-based plasma sequencing detects ctDNA in the majority of patients with advanced TKI-resistant GIST, including heterogeneity of KIT mutations. This study is the first to show that ctDNA sequencing correlates with outcomes in pretreated GIST. Identification of ABP (exon13/14) KIT mutations negatively correlates with avapritinib activity.

Abstract
11541 Background: Ripretinib (R) is a switch-control tyrosine kinase inhibitor (TKI) indicated for the treatment of patients (pts) with advanced gastrointestinal stromal tumor (GIST) after prior treatment with ≥3 TKIs. In the INTRIGUE study (NCT03673501) there was no significant difference in median PFS (primary endpoint) between R and sunitinib (S). We present exploratory analyses of tolerability data and selected pt reported outcomes (PROs). Methods: Pts were randomized 1:1 to R 150 mg QD or S 50 mg QD 4 weeks on/2 weeks off.Dose modification was allowed for toxicity management. The event of interest was severe or life-threatening (grade ≥3) treatment-related adverse event prior to progression (sTRAE). Days with at least one sTRAE were summed for all treated pts and for pts with ≥1 sTRAE event. PROs were assessed using questions from EORTC QLQ-C30 and Dermatology Life Quality Index (DLQI) at cycle 1 (C1) day 1 (D1), D15, and D29; D1 and D29 of all other cycles; as well as at end of treatment. Differences in PRO scores between baseline and later assessments were calculated across visits. Long-term data will be presented. Results: Pts receiving R (n = 223) versus (vs) S (n = 221) experienced fewer sTRAEs (24% vs 51%, respectively). For all treated pts, the mean time with sTRAEs was 11 days for R and 42 days for S (ratio 0.27, P<0.0001). For pts with ≥1 sTRAE, the mean number of days with a sTRAE was 48 days for R vs 81 days for S (ratio 0.59, p = 0.037). Completion of PRO assessments across the two treatment arms was similar (baseline: R [n = 199], S [n = 199]; C1 D29: R [n = 167], S [n = 177]). Significant differences in self-reported functioning and symptoms were observed by C1 D29. For PROs relating to commonly reported sTRAEs, except constipation, pts in the R arm reported better outcomes than pts in the S arm. Pts in the R arm reported significantly (p<0.05) less decline compared to baseline in pt-reported role function as well as less increase, or improvement, in symptoms of fatigue, appetite loss, diarrhea, nausea/vomiting, and pain vs pts in the S arm. Moderate or severe effect of skin toxicity on pt life, as measured by DLQI in the R arm (n = 165) and in the S arm (n = 175), was observed in 6.6% of pts in the R arm vs 14.8% of pts in the S arm (p = 0.015). Conclusions: In the INTRIGUE study the total number of days with sTRAEs was fewer for pts receiving R vs S. Pts in the R arm also reported significantly less decline in pt-reported role function and less increase in symptoms related to commonly reported sTRAEs, except constipation, vs pts in the S arm.

Abstract
2501 Background: The immunoregulatory cytokine IL-27 upregulates inhibitory immune checkpoint receptors (eg, PD-L1, TIGIT) and downregulates proinflammatory cytokines (eg, IFNγ, TNFα). SRF388 is a fully human IgG1 blocking antibody to IL-27 with potential to promote immune activation in the tumor microenvironment. A phase 1 study was conducted to establish the preliminary safety of SRF388 and to identify recommended phase 2 doses (RP2D) suitable for monotherapy and combination expansions (NCT04374877). Methods: The dose-escalation study (accelerated single patient followed by standard 3+3) enrolled patients (pts) with advanced treatment-refractory solid tumors. Upon RP2D selection, monotherapy and combination expansions opened for treatment-refractory clear cell renal cell cancer (ccRCC), hepatocellular cancer (HCC), and non-small cell lung cancer. SRF388 was administered IV every 4 weeks (wks) as monotherapy and every 3 wks with pembrolizumab. Tumor response was assessed by RECIST1.1. Results: The monotherapy dose-escalation enrolled 29 pts with doses ranging from 0.003 to 20 mg/kg. Median age was 64 years. Most pts were female (62%) with ECOG PS of 1 (72%). Approximately 80% had prior PD-(L)1 blockade, and 48% had ≥4 prior therapies. Treatment-related adverse events (TRAEs) occurred in 21%, and all were low grade. Fatigue was the only TRAE reported in ≥10% (n = 3). No dose-limiting toxicities (DLTs) or Grade ≥3 TRAEs were observed. Median time on study was 9 wks (range 0–59). One patient with highly treatment-refractory NSCLC experienced a confirmed partial response (PR) at 8 wks that was durable for 20 wks. Nine pts (31%) experienced disease stabilization at 8 wks, with 6 of 9 exhibiting durable disease control at 6 months. Of the 7 pts with ccRCC in the dose-escalation portion of the trial, 3 (43%) experienced durable disease control for ≥20 wks (range: 20-32). With doses up to 20 mg/kg, SRF388 PK remain linear with an estimated T1/2 of 10-12 days. PK characteristics and safety profile support dosing every 3 or 4 wks. Based on safety, tolerability, PK, peripheral pSTAT1 inhibition, and preliminary efficacy, 10 mg/kg was selected as the RP2D. Both the pembrolizumab safety cohort (n = 10) and Stage 1 of the ccRCC monotherapy expansion (n = 17) have fully enrolled. Of the 10 evaluable pts with ccRCC, 1 confirmed monotherapy PR has been reported, enabling Stage 2 initiation. Changes in several serum cytokines and chemokines were observed after SRF388 administration, including expected increase in circulating IL-27 levels. Conclusions: Results of IL-27 pathway blockade with a first-in-class therapeutic demonstrates that SRF388 has good tolerability with encouraging preliminary antitumor activity as a monotherapy. Updated data, including safety and clinical outcomes as well as correlative biomarker analyses, will be presented. Clinical trial information: NCT04374877.

Abstract
4032 Background: Zani, also known as ZW25, is a novel HER2-targeted bispecific antibody that targets two distinct extracellular domains of HER2. Zani has shown preliminary antitumor activity and tolerability in pts with HER2+ gastroesophageal adenocarcinoma as monotherapy/with chemo in Phase 1/2 studies (NCT02892123, NCT03929666). TIS, an anti-PD-1 antibody, has demonstrated antitumor activity in pts with advanced solid tumors. Combining anti-HER2 therapy with anti-PD-1 therapy and chemo increased tumor response in G/GEJC in a Phase 3 clinical trial. Methods: Cohort 2 of this ongoing open-label, Phase 1b/2 study was in pts with untreated locally advanced/metastatic HER2+ G/GEJC (NCT04276493). Cohort A received zani 30 mg/kg IV, Cohort B received zani 1800 mg IV (weight < 70 kg) or 2400 mg IV (weight ≥ 70 kg), both with TIS 200 mg IV and capecitabine/oxaliplatin (CAPOX) Q3W. Primary endpoints were safety and investigator (INV)-assessed objective response rate (ORR) per RECIST v1.1. Secondary endpoints included INV-assessed duration of response (DoR), disease control rate (DCR) and progression-free survival (PFS). Results: As of Nov 26, 2021, 33 pts with a median age of 64.0 years (range: 29.0–80.0) were assigned to Cohort A (n=19) or B (n=14). Median study follow-up was 7.7 months (range: 2.1–19.0) and the median number of treatment cycles was 10 (range: 1–28), 20 (60.6%) pts remained on treatment. All pts were efficacy evaluable ([EE], n=33), confirmed ORR was 72.7% (95% CI: 54.5, 86.7). Median PFS was 10.9 months (95% CI: 6.9, NE). Efficacy data are summarized in the Table. All pts experienced ≥ 1 treatment emergent adverse event (TEAE), and 24 (72.7%) pts experienced ≥ Grade 3 TEAEs. All pts experienced treatment related TEAEs (trTEAEs), 20 (60.6%) pts experienced ≥ Grade 3 trTEAEs and trTEAEs leading to death occurred in two (6.1%) pts. Immune-mediated AEs (imAEs) occurred in nine (27.3%) pts, of which seven (21.2%) pts experienced ≥ Grade 3 imAEs. Conclusions: Zani, TIS and CAPOX combination demonstrated a manageable safety profile and antitumor activity as 1L therapy for pts with HER2+ G/GEJC. Clinical trial information: NCT04276493.

Abstract
11539 Background: Although current guidelines recommend indefinite imatinib treatment in advanced gastrointestinal stromal tumor (GIST) patients, prolonged imatinib treatment is often challenging. Imatinib-refractory progression-free survival (PFS) and overall survival were reportedly not different between those who interrupted imatinib and those did not. Methods: Clinical outcomes of 77 consecutive patients with recurrent or metastatic GIST who interrupted imatinib treatment after maintaining around 5 years of imatinib treatment in the absence of gross tumor lesions were retrospectively analyzed. Association between clinical factors and progression-free survival (PFS) following imatinib interruption was analyzed. Results: Median time from the absence of gross tumor lesions to imatinib interruption was 61.5 months (range 41.4–122.7 months). Since imatinib interruption, median PFS was 19.6 months, and the PFS rate at 60 months was 26.3%. Among patients who had progressive disease following interruption, imatinib re-introduction led to 88.6% objective response rate and 100% disease control rate, with the median imatinib-refractory PFS since re-introduction of 112.4 months. Complete removal of initial gross tumor lesion(s) (hazard ratio [HR] 0.32, 95% confidence interval [CI] 0.12–0.81, P = 0.016) and complete removal of residual gross tumor lesion(s) (HR 0.45, 95% CI 0.21–0.94, P = 0.033) by local treatment (vs. no local treatment or residual lesions after local treatment) were independently associated with favorable PFS. Conclusions: Interruption of imatinib may be considered with close surveillance in selected patients who maintained years of imatinib treatment in the absence of gross tumor lesions, especially for those who had complete removal of gross tumor lesions by local treatment.

Abstract
Purpose The phase 3 ATTRACTION-2 study demonstrated that nivolumab monotherapy improved survival compared to placebo in patients with pretreated advanced gastric cancer (AGC). However, the efficacy of nivolumab seems to be limited to a subset of patients. Materials and methods The predictive values of blood neutrophil–lymphocyte ratio (NLR), serum Na, PD-L1 expression, MSI status, tumor EBV infection, and tumor mutation burden (TMB) were investigated in patients with AGC refractory to ≥2 lines of chemotherapy enrolled from Asan Medical Center in ATTRACTION-2 study. Results All 45 patients were analyzed; nivolumab (n = 28) and placebo (n = 17) groups. The objective response rate, median progression-free survival (PFS), and overall survival (OS) were 16.7%, 1.6 months, and 8.1 months in nivolumab group and 0%, 1.6 months and 6.5 months in placebo group. When comparing nivolumab with the placebo group, tumor PD-L1 expression, blood NLR, and serum Na were significant predictive factors of PFS and OS. A multivariate analysis revealed that PD-L1 ( +) and low NLR (≤ 2.9, median) were associated with better PFS. In the nivolumab group, PD-L1 ( +), low NLR, and normal Na (≥ 135 mmol/L) were associated with higher response and disease control rates, while tumor EBV infection and TMB were not. Conclusion Tumor PD-L1 expression, blood NLR, and serum Na could be predictive biomarkers for the efficacy of nivolumab in previously treated cases of AGC.

Abstract
Background Retrospective studies have suggested a potential risk of hyperprogressive disease (HPD) in patients receiving immune checkpoint inhibitors (ICIs). We compared the incidence of HPD during treatment with nivolumab±ipilimumab versus natural tumor progression with placebo in post hoc analyses of two randomized, double-blind clinical trials. Methods ATTRACTION-2 randomized patients with advanced gastric or gastroesophageal junction cancer (GC/GEJC) and progression on ≥2 prior regimens to nivolumab 3 mg/kg Q2W or placebo. CheckMate 451 randomized patients with extensive-disease small cell lung cancer (ED SCLC) and ongoing complete/partial response or stable disease after first-line chemotherapy to nivolumab 240 mg Q2W, nivolumab 1 mg/kg+ipilimumab 3 mg/kg Q3W for four doses then nivolumab 240 mg Q2W, or placebo. Patients receiving ≥1 dose of study drug and with tumor scans at baseline and the first on-treatment evaluation were included in the HPD analyses. HPD definitions were ≥20%, ≥50%, and ≥100% increase in target lesion sum of the longest diameters (SLD) at the first on-treatment assessment. Results In the ATTRACTION-2 HPD-evaluable population, 243 patients received nivolumab and 115 placebo. Fewer patients receiving nivolumab versus placebo had increases in SLD ≥20% (33.7% vs 46.1%) and ≥50% (6.2% vs 11.3%); similar proportions had increases in SLD ≥100% (1.6% vs 1.7%). In the CheckMate 451 HPD-evaluable population, 177 patients received nivolumab, 179 nivolumab+ipilimumab, and 175 placebo. Fewer patients receiving nivolumab or nivolumab+ipilimumab versus placebo had increases in SLD ≥20% (27.1%, 27.4% vs 45.7%), ≥50% (10.2%, 11.2% vs 22.3%), and ≥100% (2.8%, 2.8% vs 6.3%). Conclusions Nivolumab±ipilimumab was not associated with an increased rate of progression versus placebo in patients with GC, GEJC, or ED SCLC, suggesting that previous reports of HPD may reflect the natural disease course in some patients rather than ICI-mediated progression. Trial registration number NCT02538666; NCT02267343.

Abstract
344 Background: ICI with anti-PD-1 therapy was approved by the US FDA as 1st/2nd-line treatment of advanced GEC regardless of PD-L1 status. It is argued that patients (pts) with PD-L1-low GEC do not benefit from ICI. To avoid spurious exclusion of pts, we systematically reviewed phase 3 trials to assess the magnitude and consistency of PD-L1 to predict benefit from ICI. We also examined other potential predictive factors to understand their magnitude and consistency in comparison with PD-L1 status. Methods: MEDLINE, Embase, Scopus, Web of Science, and Cochrane Central Register were searched for all randomized clinical trials (RCT; 2000-2021) in advanced GEC comparing ICI, alone or with chemotherapy, vs standard of care (SOC). The primary endpoint was overall survival (OS). Study screening, data abstraction, and bias assessment were done independently by two reviewers per PRISMA guidelines. The mean HR for ICI vs SOC was calculated by random effects model. The predictive value of a factor was quantified using relative magnitude and consistency (table). Results: 14 RCTs at low risk of bias were included (N = 9,210 pts; KN62, CM649, CM648, ESCORT1st, KN590, ATT4, JAV100, KN181, KN61, ATT3, ESCORT, RATIONALE302, JAV300, ATT2). 6 trials were 1st-line, 8 were after 1st-line. Treatment comparisons were ICI + chemo vs chemo (6 trials), ICI vs chemo (9 trials), and ICI vs placebo (1 trial). ICI was always anti-PD-1/-L1 (1 trial also had anti-CTLA-4). Table shows primary results. To enable head to head comparisons, subgroup analyses of trials containing both levels of a factor or having similar design were done and generally yielded consistent results. Conclusions: PD-L1 CPS is the strongest predictive biomarker, after MSI, for OS benefit from ICI-containing therapy vs SOC. Additional research on gender is warranted.[Table: see text]

Abstract
379 Background: A single priming dose of T (anti-CTLA-4) added to D (anti-PD-L1) in the STRIDE (Single T Regular Interval D) regimen, formerly T300+D, showed encouraging clinical activity and limited toxicity in a phase 2 uHCC study (Study 22, NCT02519348), suggesting single exposure to T is sufficient to improve upon D activity. HIMALAYA (NCT03298451) evaluated the efficacy and safety of STRIDE or D vs sorafenib (S) in uHCC. Methods: HIMALAYA is an open-label, multicenter, phase 3 study, in which pts with uHCC and no prior systemic therapy were initially randomized to STRIDE (T 300 mg plus D 1500 mg [one dose] plus D 1500 mg every 4 weeks [Q4W]), D (1500 mg Q4W), S (400 mg twice daily), or T 75 mg Q4W (4 doses) plus D 1500 mg Q4W (T75+D). Recruitment to T75+D ceased after a planned analysis of Study 22 showed T75+D did not meaningfully differ from D. The primary objective was overall survival (OS) for STRIDE vs S. The secondary objective was OS noninferiority (NI) of D to S (NI margin: 1.08). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR; RECIST v.1.1), duration of response (DoR), and safety. Results: In total, 1171 pts were randomized to STRIDE (N=393), D (N=389), or S (N=389). At data cutoff (DCO), the primary objective was met: OS was significantly improved for STRIDE vs S (hazard ratio [HR], 0.78; 96% confidence interval [CI], 0.65–0.92; p=0.0035; Table). D met the objective of OS NI to S (HR, 0.86; 96% CI, 0.73–1.03). ORRs were higher for STRIDE (20.1%) and D (17.0%) than for S (5.1%). No new safety signals were identified. Grade 3/4 treatment-related adverse events (TRAEs) occurred in 25.8% (STRIDE), 12.9% (D), and 36.9% (S) of pts. Grade 3/4 hepatic TRAEs occurred in 5.9% (STRIDE), 5.2% (D), and 4.5% (S) of pts. No TRAE of esophageal varices hemorrhage occurred. Rates of TRAEs leading to discontinuation were 8.2% (STRIDE), 4.1% (D), and 11.0% (S). Conclusions: HIMALAYA was the first large phase 3 trial with a diverse, representative uHCC population and extensive long-term follow-up to assess both mono- and combination immunotherapy. D was noninferior to S with favorable safety. The combination of a single priming dose of T plus D in STRIDE displayed superior efficacy and a favorable benefit-risk profile vs S. STRIDE is a proposed, novel, first-line standard of care systemic therapy for uHCC. Clinical trial information: NCT03298451. [Table: see text]

Abstract
436 Background: The phase 2 Study 22 trial (NCT02519348) investigated durvalumab (anti-programmed cell death ligand-1 [PD-L1] antibody) and tremelimumab (anti-cytotoxic T-lymphocyte associated antigen 4 antibody) as monotherapy, or durvalumab in combination with tremelimumab or bevacizumab (anti-vascular endothelial growth factor [VEGF] antibody), for the treatment of patients with unresectable hepatocellular carcinoma (uHCC). Results of Study 22 that evaluated durvalumab and tremelimumab as monotherapy or in combination were reported previously. PD-L1 inhibition plus VEGF inhibition with bevacizumab may exhibit an additive effect to improve clinical activity. Herein, we report results from a single-arm cohort of Study 22, evaluating durvalumab plus bevacizumab as first-line treatment in patients with uHCC. Methods: Patients with uHCC who had not received any prior systemic therapy were administered durvalumab 1120 mg plus bevacizumab 15 mg/kg once every 3 weeks. Adequate endoscopic therapy according to institutional standards was required for patients with a history of gastrointestinal bleeding for >12 months or those at high risk for esophageal varices. The primary endpoint was safety. Secondary endpoints included confirmed objective response rate (ORR; assessed by blinded independent central review [BICR] according to RECIST v1.1), duration of response (DoR; RECIST v1.1 by BICR) and overall survival (OS). Results: At the data cut-off (November 6, 2020), 47 patients were allocated to receive treatment. Median total treatment duration was 6.2 months (durvalumab) and 4.1 months (bevacizumab). Thirty-three (70.2%) patients experienced an adverse event possibly related to treatment (TRAE). Grade 3 or 4 TRAEs occurred in 4 (8.5%) patients; serious TRAEs occurred in 5 (10.6%) patients, including gastric ulcer perforation, ascites, and liver tumor rupture, possibly related to bevacizumab, and raised creatinine and pneumonitis, possibly related to durvalumab. There were 3 (6.4%) discontinuations and no deaths associated with TRAEs. Objective responses (RECIST 1.1 by BICR) were confirmed in 10 patients (ORR, 21.3%; 95% CI, 10.7–35.7); median DoR (RECIST 1.1 by BICR) was not reached. Median OS was not reached (95% CI, 12.52 months–non-estimable). Conclusions: Durvalumab plus bevacizumab was well tolerated and showed promising clinical activity in patients with uHCC. Durvalumab with or without bevacizumab in combination with transarterial chemoembolization is being investigated as locoregional therapy in patients with HCC not amenable to curative treatment in the phase 3 EMERALD-1 study (NCT03778957), and durvalumab with or without bevacizumab is being investigated in patients with HCC at high risk of recurrence after curative treatment in the phase 3 EMERALD-2 study (NCT03847428). Clinical trial information: NCT02519348.

Abstract
Triple negative breast cancer (TNBC) is prone to recurrence and metastasis, which is the subtype of poorest prognosis. Chemotherapy is the main treatment, although there is lack of effective adjuvant chemotherapy regimens. The unsatisfactory efficacy of chemotherapy has been a bottleneck in improving the outcome of TNBC. Platinum compounds act directly on DNA to kill tumor cells, and they have a stronger killing effect on tumor cells carrying DNA damage repair (DDR) defects, which is an important entry point to improve the efficacy of TNBC. Biomarkers for predicting the efficacy of platinum drugs in TNBC treatment have always been a hot topic. The DDR pathway contains a large number of related genes, and recent studies have shown that deficiencies in the DDR pathway may be associated with the efficacy of platinum drugs, which is expected to be a biomarker for predicting the efficacy of platinum drugs in breast cancer treatment.
