Abstract
For inoperable esophageal adenocarcinoma (EAC), identifying patients likely to benefit from recently approved immunochemotherapy (ICI+CTX) treatments remains a key challenge. We address this using a uniquely designed window-of-opportunity trial (LUD2015-005), in which 35 inoperable EAC patients received first-line immune checkpoint inhibitors for four weeks (ICI-4W), followed by ICI+CTX. Comprehensive biomarker profiling, including generation of a 65,000-cell single-cell RNA-sequencing atlas of esophageal cancer, as well as multi-timepoint transcriptomic profiling of EAC during ICI-4W, reveals a novel T cell inflammation signature (INCITE) whose upregulation correlates with ICI-induced tumor shrinkage. Deconvolution of pre-treatment gastro-esophageal cancer transcriptomes using our single-cell atlas identifies high tumor monocyte content (TMC) as an unexpected ICI+CTX-specific predictor of greater overall survival (OS) in LUD2015-005 patients and of ICI response in prevalent gastric cancer subtypes from independent cohorts. Tumor mutational burden is an additional independent and additive predictor of LUD2015-005 OS. TMC can improve patient selection for emerging ICI+CTX therapies in gastro-esophageal cancer.

Abstract
Abstract
For patients with inoperable esophageal adenocarcinoma (EAC), prognosis on conventional chemotherapy (CTX) remains poor. In 2021, the FDA approved two αPD-1 immune checkpoint inhibitors (ICI) for addition to fluoropyrimidine/platinum-containing CTX in this first-line setting. As ICI+CTX enters the clinic, understanding ICI responses and predicting which patients will benefit from ICI addition are key challenges. To address these challenges, we assessed clinical and molecular profiles from the experimental LUD2015-005 trial (NCT02735239, EudraCT 2015-005298-19). Treatment consisted of an initial four-week ICI-only window with durvalumab (αPD-L1) with or without a single dose of tremelimumab (αCTLA-4), followed by 6 cycles of ICI+CTX (CapOx). 38 inoperable patients received treatment (35 EAC; 3 ESCC); median overall survival (OS) and progression-free survival (PFS) were 13.4 and 9.3 months, respectively. All patients reported at least one treatment emergent adverse event (TEAE), with 29 (76.3%) reporting grade 3 or higher TEAEs. EAC patients with available samples (n = 33) were taken forward for biomarker analysis, using tumor and adjacent normal biopsies collected at pre-treatment (PreTx), after four weeks of ICI-only (ICI-4W), and at the end of ICI+CTX (PostTx).
Transcriptomic comparison of paired PreTx and ICI-4W EAC biopsies (n = 28) revealed ICI-induced upregulation of a novel T-cell inflammation signature (termed INCITE). Stronger INCITE upregulation correlated with greater tumor shrinkage during the ICI-only window, and tumors with minimal INCITE upregulation showed markers of ICI resistance, including Innate PD-1 Resistance (IPRES). Despite correlation with ICI-only responses, INCITE changes were not associated with overall ICI+CTX outcomes.
To find predictive biomarkers of ICI+CTX outcomes, we conducted comprehensive genomic and transcriptomic profiling of PreTx EAC biopsies (n = 33). First, we generated a novel 65,000 cell scRNA-seq dataset and designed a deconvolution workflow to resolve tumor cell composition. Unexpectedly, monocyte composition was strongly linked with greater overall survival (OS) (HR: 0.40 [0.23-0.69]; p = 0.001; FDR = 0.047). Coding tumor mutational burden (TMB) was also associated with improved OS (HR: 0.50 [0.28-0.89]; p = 0.019). Multivariate modelling suggested monocyte composition and TMB were independent and complementary predictors of outcomes. Neither factor was associated with outcomes in a TCGA cohort of EAC patients not treated with ICI, suggesting these biomarkers may be specific to ICI or ICI+CTX.
Our findings suggest monocyte composition and TMB may identify EAC patients likely to benefit from ICI+CTX. INCITE upregulation may also serve as a useful monitor of ICI efficacy. These timely findings further our understanding of ICI response and resistance and may help inform patient selection for ICI+CTX.

Abstract
2600 Background: Locoregional treatment with oncolytic viruses may be used to improve the efficacy of immune checkpoint inhibitors at both treated and distant tumor sites. This study evaluated the combination of IP-administered ONCOS-102, an oncolytic adenovirus encoding for granulocyte macrophage colony stimulating factor (GM-CSF), with systemic durvalumab (durva) in patients (pts) with advanced OC or CRC who have failed prior chemotherapy. Methods: This open-label study (NCT02963831) evaluated ONCOS-102 (IP 3 x 1011 VP in 500ml saline [recommended phase 2 dose] weekly x 6) + durva (IV 1500 mg every 4 weeks x 12). One dose of cyclophosphamide was given prior to first ONCOS-102 dose. Phase 2 evaluated the activity of the combination using Simon’s 2-stage MINIMAX design. In MINIMAX stage 1, if ≥ 5 of 18 OC pts or ≥ 1 of 13 CRC pts met the efficacy criteria (progression free at end of week 24), 15 additional OC pts or 14 additional CRC pts were to be enrolled in stage 2. The efficacy endpoint would be met if ≥ 11 OC pts or ≥ 4 CRC pts remained progression free at 24 weeks. Safety, response rate and progression-free survival (PFS) by RECIST 1.1, overall survival (OS), and immunologic effects in tumors were evaluated. ITT population = all pts who received at least one dose of durva or ONCOS-102; per protocol (PP) population = all pts who received at least 60% of ONCOS-102 doses and at least 1 durva dose in the first 2 cycles. Results: In MINIMAX stage 1, the OC cohort did not meet the efficacy criteria and was closed. For CRC, stage 1 efficacy criteria were achieved and the cohort was opened for stage 2. As of the 14 Dec 2021 cutoff, CRC enrollment was complete, and all pts were followed for 24 weeks or until progression or off study. Two pts were progression free at 24 weeks (see table). Treatment-related adverse events (TRAEs) occurring in > 30% pts were vomiting, nausea, fatigue, chills, and pyrexia. There were no grade 4 or 5 TRAEs. Grade 3 TRAEs were reported in 8 pts, 2 in the OC cohort and 6 in CRC. All grade 3 TRAEs occurred in no more than 1 pt for each AE except abdominal pain, which occurred in 2 pts. Conclusions: The combination of IP ONCOS-102 and durva was well tolerated. The study did not meet its efficacy endpoint. Evaluation of pre- and on-therapy translational parameters is ongoing. Clinical trial information: NCT02963831. [Table: see text]

Abstract
Ipilimumab (IPI) can enhance immunity to the cancer-testis antigen NY-ESO-1. A clinical trial was designed to assess safety, immunogenicity, and clinical responses with IPI + NY-ESO-1 vaccines and effects on the tumor microenvironment (TME). Patients with measurable NY-ESO-1+ tumors were enrolled among three arms: A) IPI + NY-ESO-1 protein + poly-ICLC (pICLC) + incomplete Freund’s adjuvant (IFA); B) IPI + NY-ESO-1 overlapping long peptides (OLP) + pICLC + IFA; and C) IPI + NY-ESO-1 OLP + pICLC. Clinical responses were assessed by irRC. T cell and Ab responses were assessed by ex vivo IFN-gamma ELIspot and ELISA. Tumor biopsies pre- and post-treatment were evaluated for immune infiltrates. Eight patients were enrolled: 5, 2, and 1 in Arms A-C, respectively. There were no DLTs. Best clinical responses were SD (4) and PD (4). T-cell and antibody (Ab) responses to NY-ESO-1 were detected in 6 (75%) and 7 (88%) patients, respectively, and were associated with SD. The breadth of Ab responses was greater for patients with SD than PD (p = .036). For five patients evaluable in the TME, treatment was associated with increases in proliferating (Ki67+) CD8+ T cells and decreases in RORγt+ CD4+ T cells. T cell densities increased for those with SD. Detection of T cell responses to NY-ESO-1 ex vivo in most patients suggests that IPI may have enhanced those responses. Proliferating intratumoral CD8+ T cells increased after vaccination plus IPI suggesting favorable impact of IPI plus NY-ESO-1 vaccines on the TME. List of Abbreviations: Ab = antibody; CTCAE = NCI Common Terminology Criteria for Adverse Events; DHFR/DHRP = dihydrofolate reductase; DLT = Dose-limiting toxicity; ELISA = enzyme-linked immunosorbent assay; IFA = incomplete Freund’s adjuvant (Montanide ISA-51); IFNγ = Interferon gamma; IPI = Ipilimumab; irRC = immune-related response criteria; mIFH = multispectral immunofluorescence histology; OLP = NY-ESO-1 overlapping long peptides; PBMC = peripheral blood mononuclear cells; PD = Progressive disease; pICLC = poly-ICLC (Hiltonol), a TLR3/MDA-5 agonist; RLT = Regimen-limiting Toxicity; ROI = regions of interest; RT = room temperature; SAE = serious adverse event; SD = stable disease; TEAE = treatment-emergent adverse events; TLR = toll-like receptor; TME = tumor microenvironment; TRAE = treatment-related adverse events.

Abstract
3017 Background: Metastasis to the peritoneal cavity is associated with end-stage disease in many cancers, including OC and CRC, both of which exhibit poor responses to checkpoint inhibitors. Locoregional treatment with oncolytic viruses may be used to improve the efficacy of checkpoint inhibitors at both treated and distant tumor sites. This study evaluates the combination of IP-administered ONCOS-102, an oncolytic adenovirus encoding for granulocyte macrophage colony stimulating factor (GMCSF), with systemic durvalumab, an anti PD-L1 antibody, in patients with peritoneal disease who have histologically confirmed OC or metastatic CRC and have failed prior standard therapies. Methods: This ongoing Phase 1/2, open-label study (NCT02963831) evaluates safety and antitumor/biologic activity of durvalumab (1500 mg IV, every 4 weeks x 12) + ONCOS-102 (IP, weekly x 6); cyclophosphamide is given pre first ONCOS-102 dose. Phase 1 uses a 3+3 design to evaluate the ONCOS-102 dose (1 or 3 x 1011 VP) to be given with durvalumab. Phase 2 evaluates the activity of the combination using Simon’s 2-stage MINIMAX design. Safety, response rate by RECIST 1.1, and immunological effects in tumors were evaluated for Phase 1; the current abstract reports on the phase 1 results. Results: Enrollment opened 7 Sep 2017; data cutoff, 1 Nov 2019. There were 17 patients treated in Phase 1: 8 CRC, 9 ovarian; 94% female; median age, 56 [37-77] years; ECOG PS0, 47%; ECOG PS1, 53%. There were no DLTs. Grade 3 treatment-related AEs included hypokalemia (n = 2); anemia, myocarditis, increased GGT, and influenza like illness (n = 1 each). There were 4 deaths due to PD. One patient had durable confirmed partial response and remains on treatment > 1 year; 4 patients had stable disease as best overall response. Two patients remained on treatment at data cutoff. Analysis of pre- and on-treatment tumor biopsies revealed changes in the tumor-infiltrating immune cells and PD-L1 expression, including an increase in tumor-infiltrating CD8 T cells in 5 of 11 evaluable patients. Conclusions: Combination of durvalumab and IP ONCOS-102 was safe, and no DLTs were observed. Preliminary analyses demonstrate evidence of biologic and clinical activity. Phase 2 enrollment is ongoing. Clinical trial information: NCT02963831 .

Abstract
2032 Background: Durvalumab (durva), a human IgG1 monoclonal Ab against PD-L1, is FDA-approved for selected patients with bladder and non-small cell lung cancers. PD-L1 is expressed by some GBM tumors, while GBM infiltrating T lymphocytes often express PD-1. Radiation induced cell death releases tumor antigens and could potentiate anti-PD-(L)1 therapy. Methods: This ongoing Phase 2 open-label study (NCT02336165) evaluates the safety and efficacy of durva (10 mg/kg every 2 weeks) in 5 GBM cohorts. Results are presented for Cohort A, which evaluates durva + standard radiotherapy (RT, 60 Gy over 30 fractions) followed by durva monotherapy in patients with new unmeth GBM after maximum safe resection. The primary efficacy endpoint for Cohort A is overall survival at 12 months (OS12); secondary endpoints include safety/tolerability, tumor response rate, and progression-free survival (PFS). Historical benchmarks of median OS and OS12 for patients with new unmeth GBM following standard therapy are 12.7 months and 50%, respectively (EORTC 26981-22981/NCIC CE.3). Results: Median follow-up of 40 enrolled patients is 24.5 months (data cutoff = 05 Nov 2018). Baseline characteristics: male, 70%; median age, 57.0 [22 to 77] years; ECOG PS0, 60.0%; ECOG PS1, 40.0%; measurable disease, 80.0%; and dexamethasone use, 32.5%. Treatment-related adverse events with maximum CTCAE grade ≥ 3 occurred in 14 (35.0%) patients; the most common were asymptomatic increased lipase (n = 6) and increased amylase (n = 2). Twenty-four of 40 patients were alive at 12 months (Kaplan-Meier for OS12, 60.0% [90% CI: 46.1, 71.4]). Median OS was 15.1 (95% CI: 12.0, 18.4) months. As of 05 Nov 2018, 8 (20%) patients remain alive, with ongoing survival ranging from 15.7 to 34.9 months. Tumor immunocorrelative and systemic studies are pending. Conclusions: This is the first study report of anti-PD-L1 for new GBM. Durva was well tolerated when combined with RT and seemed to have efficacy among patients with new unmeth GBM. Further studies may be warranted. Clinical trial information: NCT02336165.

Abstract
TPS3106 Background: Immunotherapy has demonstrated promising antitumor activity in various advanced cancers. Combined tumor targeting from multiple drugs with unique mechanisms may provide further improved outcomes. Tremelimumab (TRE) is a CTLA-4 antibody and durvalumab (DUR) blocks PD-L1. Poly-ICLC is a toll-like receptor 3 agonist. Intratumoral (intra-T) injection of poly-ICLC directly alters the tumor microenvironment (TME), and by creating an in situ vaccination, may trigger a clinically effective systemic anti-tumor response when also combined with DUR and TRE. Methods: This is an ongoing Phase 1/2, open-label, multicenter study (NCT02643303). The study evaluates the use of intra-T administration of TRE and IV DUR + poly-ICLC (intra-T and intramuscular [IM]) to determine the safety, preliminary efficacy and immune activity of this regimen in patients with advanced, measurable, biopsy-accessible tumors: head and neck squamous cell carcinoma, breast cancer, sarcoma, merkel cell carcinoma, cutaneous T-cell lymphoma, melanoma, genitourinary cancer, and other solid tumors. Phase 1 determines the recommended combination dosing (RCD) for the regimen with dose de-escalation based on dose limiting toxicities (DLTs) and standard 3 + 3 rules. Starting doses are: DUR, 1500 mg IV; TRE, 75 mg IV; TRE, 10 mg intra-T; poly-ICLC, 1 mg intra-T/IM. Phase 1 starts with Cohort 1A (DUR + poly-ICLC). Upon demonstration of tolerability, enrollment proceeds with Cohort 1B (DUR + IV TRE + poly-ICLC) and Cohort 1C (DUR + intra-T TRE + poly-ICLC). The RCD is the highest dose at which < 2/6 patients have DLTs. In Phase 2, up to 66 evaluable patients are treated using the RCD regimen, with enrollment of 6 patients per tumor type initially, and enrollment of 6 additional patients per 3 tumor types contingent upon at least 1 response among the initial 6 patients. Study endpoints are RCD and safety, objective response rate, progression-free survival, and overall survival. Exploratory endpoints are biological activity, including effects on the TME and immunological responses. Enrollment opened on 28 Dec 2016. Clinical trial information: NCT02643303.

Abstract
TPS8051 Background: Multiple myeloma (MM) remains an incurable hematologic malignancy despite the advent of new classes of drugs, including immunomodulatory agents, proteasome inhibitors, and monoclonal antibodies. The success and synergistic activity of immunotherapy (IMT) in solid tumors and hematologic malignancies has fueled their investigation in MM. HDT/ASCT as consolidation or as treatment for relapse remains a cornerstone for improving overall survival. HDT/ASCT transiently eliminates immune-suppressive cell populations and provides a viable IMT platform. Reinfusion of PBLs harvested pre-HDT induces immune responses, supporting its inclusion in IMT combinations. This study evaluates the effect of IMT, using tremelimumab (T), an anti-CTLA-4 monoclonal antibody, and durvalumab (D), an anti-PD-L1 monoclonal antibody, together with autologous PBL reinfusion and starting T ± D at Day 100 and earlier (Day 30) post-ASCT. Methods: This ongoing Phase 1, open-label, multicenter study (NCT02716805) evaluates the safety and preliminary efficacy of T and D administered on 2 schedules in MM patients at high risk for relapse as outlined below. Cohort initiation requires dose-limiting toxicity in < 2/6 patients in the previous cohort. The primary endpoint is safety. Secondary endpoints are objective response rate per IMWG, minimal residual disease, progression free and overall survival, and 100-day ASCT-related mortality. Exploratory endpoints include immunological effects and immune response. Enrollment opened 18 Nov 2016. As of 31 Dec 2016, 1 patient is enrolled in Cohort 1; enrollment is ongoing. Clinical trial information: NCT02716805. [Table: see text]

Abstract
2042 Background: DUR is a human IgG1 monoclonal Ab against PD-L1. PD-1/PD-L1 blockade has shown benefit in solid tumors. PD-L1 is expressed by many GBM tumors while cytotoxic lymphocytes infiltrating GBM tumors often express PD-1; thus, there is a rationale for exploring PD-1/PD-L1 blockade in GBM. Bevacizumab (BEV) is a VEGF-specific angiogenesis inhibitor approved for recurrent GBM. PD-L1 blockade and angiogenesis inhibition may be synergistic. Methods: This ongoing Phase 2, multicenter, open-label study (NCT02336165) evaluates safety/efficacy of DUR (10 mg/kg every 2 wks) in 5 GBM cohorts. Secondary endpoints are safety/tolerability, median PFS/OS, overall response rate and quality of life measures. Exploratory endpoints: neurologic function and immunocorrelative biomarkers. Results: Enrollment as of 16 Dec 2016: Cohort A = 35, B = 31, B2 = 34, B3 = 34, and C = 20 pts. Enrollment is ongoing for Cohorts A and C. This is an update to the interim analysis that was reported for Cohort B (male: 83.9%; mean age: 54.0 [24-77] years; baseline ECOG PS0: 51.6%, PS1: 48.4%; baseline measurable lesions: 77.4%). Incidences of treatment-related adverse events (TRAEs) by max CTCAE grade (Gr) were Gr1: 35.5%; Gr2: 41.9%; Gr3: 9.7%; and Gr4/5: 0%. Most common TRAEs (≥3 pts): fatigue, headache, hemiparesis, gait disturbance, increased AST, and decreased platelets/WBCs/lymphs. Six of 30 evaluable pts were progression free at 6 months (Kaplan-Meier, 20.0% [90% CI: 9.7, 33.0]); best overall response: partial response, 4 (13.3%) pts and stable disease, 14 (46.7%). At 1 year, 4 pts remained progression free (longest PFS ongoing at 80 wks, n=2). OS-6 and OS-12 are 59.0 and 44.4%, respectively. As of 16 Dec 2016, 7 pts remain alive (longest OS ongoing at 86 wks). Conclusions: DUR monotherapy appears to be well tolerated and shows durable activity in a subset of BEV-naïve recurrent GBM pts. Study is ongoing. Clinical trial information: NCT02336165.

Abstract
3069 Background: DUR is a human IgG1 monoclonal antibody (mAb) that blocks PD-L1. TRE is a human IgG2 mAb inhibitor of CTLA-4. Blocking these checkpoints can result in antitumor activity in some solid tumors. The targets for DUR and TRE are non-redundant, providing sound rationale for clinical testing of the combination. Methods: This is an ongoing Phase 1, multicenter, open label study (NCT01975831) with a dose escalation (3+3 design) and subsequent expansion phase. Patients (pts) with renal cell carcinoma (RCC), cervical (CC), colorectal (CRC), non-triple-negative breast (NTNBC), ovarian (OC), non-small cell lung, or head and neck cancer are eligible. Primary endpoints are safety/tolerability and identification of maximum tolerated dose (MTD) of the combination. Secondary objectives include tumor response and progression-free/overall survival. Results: As of 16 Dec 2016, 105 pts were treated. DUR 1500 mg every 4 weeks (Q4W) and TRE 75 mg Q4W X 4 was the regimen used for opening the expansion phase. Dose-limiting toxicities were reported in 4 pts: diarrhea, colitis, abnormal liver function tests (abn LFTs), and hyponatremia. The majority of treatment-related AEs (TRAEs) were Grades (Gr) 1 and 2. TRAEs ≥ Gr 3 were reported in 12 pts; the majority were diarrhea/colitis (n = 5) and abn LFTs (n = 4) and responded to established treatment algorithms. There was 1 Gr 5 TRAE: multi organ failure. No new toxicities were identified. The preliminary responses by tumor type with n ≥ 10 pts are shown in the table below. Responses were seen in OC and RCC at the Cohort 2 dose escalation level (DUR 1/TRE 3 mg/kg). There were 4 cases of SD > 24 weeks: CC, n=2; CRC, n=1; OC, n=1. PD-L1 status was not tested. Conclusions: The DUR + TRE combination has a manageable safety profile, with preliminary evidence of clinical activity. These data support continued study of the combination therapy; the study is ongoing. Clinical trial information: NCT01975831. [Table: see text]

Abstract
TPS9591 Background: Immunotherapy (IMT) with checkpoint blocking antibodies has led to progress in metastatic melanoma with 3 FDA-approved drugs, including the combination of ipilimumab (IPI), a CTLA-4 antibody, and nivolumab (NIVO), a PD-1 antibody. Although radiotherapy (RT) is primarily used as local palliative therapy in metastatic melanoma, it also possibly affects systemic antitumor immunity. Preclinical data suggest RT alters the tumor microenvironment and renders tumor cells more susceptible to immunologically-mediated disease regression. These preclinical immunologic effects of RT have been shown to vary by RT dose and fractionation. We are now conducting the first clinical trial in patients to evaluate the triple combination of IPI + NIVO + RT using 2 different dose/fractionation schemes of RT. Methods: This ongoing Phase 1, open-label, multicenter study (NCT02659540) evaluates safety, efficacy, and immunologic effects of IPI + NIVO + RT in 18 patients with unresectable stage IV melanoma. Patients must have 1 melanoma metastasis that can be safely irradiated for palliative purposes and at least 1 measurable lesion that will not be irradiated. Patients receive concurrent IPI (3 mg/kg) and NIVO (1 mg/kg) every 3 weeks (Q3W) x 4, followed by NIVO monotherapy (240 mg Q2W), with RT initiated between the first and second doses of IPI + NIVO. In Cohort A, the irradiated metastasis receives a conventionally fractionated low dose of 30 Gy in 10 fractions of 3 Gy each over 2 weeks. If ≤7 of 9 patients (78%) in Cohort A have Grade 3/4 drug- or radiation-related adverse events, safety is deemed acceptable and Cohort B enrollment opens. In Cohort B, the irradiated metastasis receives a hypofractionated high dose of 27 Gy in 3 fractions of 9 Gy each over 2 weeks. The primary endpoint is safety. Secondary endpoints are objective response rate and disease control rate by RECIST and immune-related RECIST measured at Weeks 12 and 18, duration of response, progression-free survival, and overall survival. Exploratory endpoints include correlative studies of immunological effects. Enrollment opened on 05 Aug 2016. As of 31 Dec 2016, 4 patients are enrolled in Cohort A; enrollment is ongoing. Clinical trial information: NCT02659540.

Abstract
This article examines the use of supplemental food programs by two Native American populations and assesses some of the health and cultural impacts of these programs. A cross-sectional survey of 80 American Indian families, 40 families residing on the Round Valley Indian Reservation and 40 in Sacramento, California was conducted to determine access, use and appropriateness of supplemental feeding programs. Respondents at both the rural and urban geographic location showed considerable familiarity with available supplemental feeding programs. USDA Food Commodities were utilized most at Round Valley, raising the concern that provided staples which were highly processed and contained significant amounts of sodium, sucrose, and fat, could contribute to the problems of obesity and diabetes. Native Americans in Sacramento used food banks and food closets as their primary source of supplemental foods, and some expressed concern that the foods provided were highly sweetened and high in fat. While some nutrition advising was available at both geographical localities, access was inadequate. The study found that the foods provided by the supplemental food programs varied considerably in their nutritional quality and healthier foods such as fresh fruits, vegetables, and meats were either completely lacking or in short supply. In addition, culturally sensitive nutritional counseling and the development of education modules to instruct program recipients in the preparation of healthy meals and how to manage obesity and diabetes were needed and requested within the California Native American communities surveyed.
