Abstract
Recurrence of hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) after liver transplant (LT) is mediated by circulating tumour cells (CTCs) and exacerbated by the immunosuppressants required to prevent graft rejection. To circumvent the effects of immunosuppressants, we developed immunosuppressive drug-resistant armoured HBV-specific T-cell receptor-redirected T cells (IDRA HBV-TCR). However, their ability to eliminate HBV-HCC circulating in the whole blood has never been tested, and whether their lytic efficacy is compatible with the number of adoptively transferred T cells in vivo has never been measured. Hence, we developed a microscopy-based assay to quantify CTCs in whole blood. The assay was then used to quantify the efficacy of IDRA HBV-TCRs to lyse free-floating HBV-HCC cells in the presence of Tacrolimus and Mycophenolate Mofetil (MMF). We demonstrated that a panel of antibodies (AFP, GPC3, Vimentin, pan-Cytokeratin, and CD45) specific for HCC tumour antigens and immune cells can effectively differentiate HCC-CTCs in whole blood. Through dose-titration experiments, we observed that in the presence of immunosuppressive drugs, a minimum of 20 000 IDRA HBV-TCR T cells/ml of whole blood is necessary to lyse ~63.5% of free-floating HBV-HCC cells within 16 hours. In conclusion, IDRA HBV-TCR T cells can lyse free-floating HBV-HCC cells in whole blood in the presence of Tacrolimus and MMF. The quantity of IDRA-HBV TCR T cells required can be achieved by the adoptive transfer of 5 × 106 IDRA-HBV TCR-T cells/kg, supporting the utilisation of IDRA HBV-TCR T cells to eliminate CTCs as prophylaxis against recurrence after LT.

Abstract
Introduction Immune checkpoint blockade (ICB) is a systemic therapeutic option for advanced hepatocellular carcinoma (HCC). However, low patient response rates necessitate the development of robust predictive biomarkers that identify individuals who will benefit from ICB. A 4-gene inflammatory signature, comprising CD8, PD-L1, LAG-3, and STAT1, was recently shown to be associated with a better overall response to ICB in various cancer types. Here, we examined whether tissue protein expression of CD8, PD-L1, LAG-3, and STAT1 predicts response to ICB in HCC. Methods HCC samples from 191 Asian patients, comprising resection specimens from 124 patients (ICB-naïve) and pre-treatment specimens from 67 advanced HCC patients treated with ICB (ICB-treated), were analyzed for CD8, PD-L1, LAG-3, and STAT1 tissue expression using multiplex immunohistochemistry followed by statistical and survival analyses. Results Immunohistochemical and survival analyses of ICB-naïve samples showed that high LAG-3 expression was associated with shorter median progression-free survival (mPFS) and overall survival (mOS). Analysis of ICB-treated samples revealed that high proportions of LAG-3+ and LAG-3+CD8+ cells pre-treatment were most closely associated with longer mPFS and mOS. Using a log-likelihood model, adding the total LAG-3+ cell proportion to the total CD8+ cell proportion significantly increased the predictive values for mPFS and mOS, compared with the total CD8+ cell proportion alone. Moreover, levels of CD8 and STAT1, but not PD-L1, were significantly correlated with better responses to ICB. After analyzing viral-related and non-viral HCC samples separately, only the LAG3+CD8+ cell proportion was significantly associated with responses to ICB regardless of viral status. Conclusion Immunohistochemical scoring of pre-treatment levels of LAG-3 and CD8 in the tumor microenvironment may help predict ICB benefits in HCC patients. Furthermore, immunohistochemistry-based techniques offer the advantage of being readily translatable in the clinical setting.

Abstract
Introduction Sorafenib was historically the standard of care for advanced hepatocellular carcinoma (aHCC) until it was superseded by the combination of atezolizumab and bevacizumab. Thereafter, several novel first-line combination therapies have demonstrated favorable outcomes. The efficacies of these treatments in relation to current and previous standards of care are unknown, necessitating an overarching evaluation. Methods A systematic literature search was conducted on PubMed, EMBASE, Scopus, and the Cochrane Controlled Register of Trials for phase III randomized controlled trials investigating first-line systemic therapies for aHCC. Kaplan-Meier curves for overall survival (OS) and progression-free survival (PFS) were graphically reconstructed to retrieve individual patient-level data. Derived hazard ratios (HRs) for each study were pooled in a random-effects network meta-analysis (NMA). NMAs were also conducted using study-level HRs for various subgroups, according to viral etiology, Barcelona Clinic Liver Cancer (BCLC) staging, alpha-fetoprotein (AFP) levels, macrovascular invasion, and extrahepatic spread. Treatment strategies were ranked using p scores. Results Among 4,321 articles identified, 12 trials and 9,589 patients were included for analysis. Only two therapies showed OS benefit over sorafenib: combined anti-programmed-death and anti-VEGF pathway inhibitor monoclonal antibodies (Anti-PD-(L)1/VEGF Ab), including atezolizumab-bevacizumab and sintilimab-bevacizumab biosimilar (HR = 0.63, 95% CI = 0.53-0.76) and tremelimumab-durvalumab (HR = 0.78, 95% CI = 0.66-0.92). Anti-PD-(L)1/VEGF Ab showed OS benefit over all other therapies except tremelimumab-durvalumab. Low heterogeneity (I2 = 0%) and inconsistency (Cochran's Q = 0.52, p = 0.773) was observed. p scores for OS ranked Anti-PD-(L)1/VEGF Ab as the best treatment in all subgroups, except hepatitis B where atezolizumab-cabozantinib ranked highest for both OS and PFS, as well as nonviral HCC and AFP ≥400 μg/L where tremelimumab-durvalumab ranked highest for OS. Conclusion This NMA supports Anti-PD-(L)1/VEGF Ab as the first-line therapy for aHCC and demonstrates a comparable benefit for tremelimumab-durvalumab which also extends to certain subgroups. Results of the subgroup analysis may guide treatment according to baseline characteristics, while pending further studies.

Abstract
INTRODUCTION Combination therapy with immune checkpoint inhibitor (ICI) and antivascular endothelial growth factor (anti-VEGF) is currently the first line treatment for advanced hepatocellular carcinoma (aHCC). However, there are many patients who may not be able to receive combination therapy due to underlying comorbidities or resource limitations. For these patients, systemic treatment options include single agent tyrosine kinase inhibitors (TKIs) or ICI monotherapy. However, whether an optimal sequence of systemic therapy exists remains unknown. We aim to explore the impact of sequencing of TKI and ICI therapy in terms of response rates and to examine the safety of their use in sequential order. METHODS Patients with aHCC treated with both ICI and TKI between December 30, 2013 and June 13, 2018 were retrospectively identified. Patients were classified into two groups: those who received TKI in the first-line (TKI1), followed by ICI (ICI2) and those who received ICI (ICI1) in the first-line followed by TKI (TKI2). The primary objective of the study was to identify differences in objective response rate (ORR) and disease control rate (DCR), as evaluated based on response evaluation criteria in solid tumor v1.1 for TKI1, TKI2, ICI1, and ICI2. Secondary objectives included comparison of progression free survival (PFS) for each line of therapy, overall survival (OS) and adverse events (AEs). RESULTS Twenty-seven and 23 patients were classified into group 1 and 2, respectively. Objective response rates of TKI1 and TKI2 were 3.8% and 17.6%, respectively (p = .28); DCR to TKI1 versus TKI2 was 23.1% versus 35.3% (p = .49). ORRs of ICI1 and ICI2 were 8.7% and 14.3%, respectively (p = .66); DCR to ICI2 versus ICI1 was 56.5% versus 42.9% (p = .37). Median PFS was not significant between TKI1 and TKI2 (PFS 3.06 versus 1.61 months, p = .097) as well as between ICI2 and ICI1 (PFS 1.84 versus 2.37 month, p = .32). Median OS was also not significantly different between both groups (OS 20.63 versus 13.93 months, p = .20) on univariable and multivariable analysis (OS adjusted hazard ratio [HR] 2.07, 95% CI .83-5.18, p = .118). The proportion of patients who experienced adverse events of any grade was similar in both groups (TKI1 59.3% versus TKI2 52.2%; ICI1 78.3% versus ICI2 70.4%). CONCLUSION Our study suggests that the sequence of TKI versus ICI therapy in patients with aHCC may not matter, given similar efficacy and toxicity profile when either agent is received in the first or second-line setting. This finding is of value in the real-world setting, where patients may be frail or have comorbidities that render them unable to tolerate combination therapy (ICI and TKI/anti-VEGF). For these patients, sequential exposure to both classes of drugs (ICI and TKI) may be a suitable option.

Abstract
INTRODUCTION Development of immune-related adverse events (irAEs) has been associated with enhanced efficacy with the use of immune checkpoint inhibitors (ICIs). It remains unknown whether such an association exists in advanced hepatocellular carcinoma (aHCC). This study aims to evaluate the association between irAEs and ICI efficacy in patients with aHCC. METHODS We performed a retrospective cohort study on patients with aHCC who received at least one dose of an ICI between May 2015 and November 2019 at the National Cancer Centre Singapore. The primary study objectives were to compare the overall survival (OS) and progression-free survival (PFS) between patients with and without irAEs. Complementary multivariable landmark analyses were performed at the 6-week and 12-week landmarks. Data cutoff was December 31, 2020. RESULTS One hundred and sixty-eight patients were included. Median age was 69 years, 85.7% were male, 57.7% had hepatitis B infection, 60.7% had ECOG 0, and 78.0% had Child-Pugh A liver cirrhosis. 82.7% received ICI monotherapy, while 17.3% received ICI in combination. Development and severity of irAE were correlated with survival. The median PFS for grade ≥3 irAE versus grades 1-2 irAE versus no irAE was 8.5 versus 3.6 versus 1.3 mths (p < 0.001). The median OS for grade ≥3 irAE versus grades 1-2 irAE versus no irAE was 26.9 versus 14.0 versus 4.6 mths (p < 0.001). Patients with ≥2 irAEs had a significantly longer OS on multivariable analysis (adjusted hazard ratio [aHR]0.35, p < 0.001). The presence of grade ≥3 irAEs was associated with a significantly longer OS on the multivariable analysis at the 6-week landmark (aHR0.34, p = 0.030) and 12-week landmark (aHR0.28, p = 0.011). The use of systemic corticosteroids in patients with irAE was associated with a trend toward a longer OS (20.7 vs. 14.3 mths, p = 0.064). CONCLUSION Our study suggests that the presence of all-grade irAEs may be a potential prognostic biomarker in patients with aHCC treated with ICI. Patients with more severe irAEs and multisystem involvement have better prognosis. The prompt use of systemic corticosteroids to treat patients with irAEs is key to ensure the best long-term outcomes for these patients.

Abstract
BACKGROUND Pancreatic adenocarcinoma (PDAC) is highly lethal. Surgery offers the only chance of cure, but 5-year overall survival (OS) after surgical resection and adjuvant therapy remains dismal. Adjuvant trials were mostly conducted in the West enrolling fit patients. Applicability to a general population, especially Asia has not been described adequately. AIM We aimed to evaluate the clinical outcomes, prognostic factors of survival, pattern, and timing of recurrence after curative resection in an Asian institution. METHODS AND RESULTS The clinicopathologic and survival outcomes of 165 PDAC patients who underwent curative resection between 1998 and 2013 were reviewed retrospectively. Median age at surgery was 62.0 years. 55.2% were male, and 73.3% had tumors involving the head of pancreas. The median OS of the entire cohort was 19.7 months. Median OS of patients who received adjuvant chemotherapy was 23.8 months. Negative predictors of survival include lymph node ratio (LNR) of >0.3 (HR = 3.36, P = .001), tumor site involving the body or tail of pancreas (HR = 1.59, P = .046), presence of perineural invasion (PNI) (HR = 2.36, P = .018) and poorly differentiated/undifferentiated tumor grade (HR = 1.86, P = .058). The median time to recurrence was 8.87 months, with 66.1% and 81.2% of patients developing recurrence at 12 months and 24 months respectively. The most common site of recurrence was the liver. CONCLUSION The survival of Asian patients with resected PDAC who received adjuvant chemotherapy is comparable to reported randomized trials. Clinical characteristics seem similar to Western patients. Hence, geographical locations may not be a necessary stratification factor in RCTs. Conversely, lymph node ratio and status of PNI ought to be incorporated.

Abstract
e16181 Background: Immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs) are widely adopted in contemporary advanced HCC (aHCC) treatment algorithms. Nevertheless, the optimal strategy for treatment after ICI exposure is unknown. We evaluated the pattern of use, response, survival and safety of TKIs in aHCC patients who previously received ICIs. Methods: We performed an international, multi-centre study of aHCC patients who received TKIs after prior treatment with ICIs. Objective response rate (ORR), disease control rate (DCR), time-to-progression (TTP), overall survival (OS) and adverse events (AE) were assessed. Results: Between January 2015 and December 2020, one-hundred and forty-eight patients were included. The median age was 63 (range 29-84) and 78.4% were of Child-Pugh Grade A. 75.7% had hepatitis-B related HCC. 64.9% received TKI as single agent and 35.1% received TKI in combination with other agents. 75% who received TKI combinations had concomitant ICIs. 48.6% had prior TKIs. The median follow-up was 23.3 months. For single agent TKI patients, the ORR was 14.6%, DCR was 38.5%, median TTP was 3.9 months (95% C.I. 3.3-4.5) and median OS was 8.6 months (95% C.I. 5.8-11.4). For patients receiving TKI combinations, the ORR was 25%, DCR was 38.5%, median TTP was 3.5 months (95% C.I. 1.7-5.2) and median OS was 15.1 months (95% C.I. 5.7-24.5). There were no significant differences in ORR, DCR and median OS between patients who had primary resistance to prior ICI compared to those with acquired ICI resistance and between those who were TKI-naive compared to those who were TKI-exposed. Notably, patients who received TKI-ICI combinations had significantly superior survival compared to single agent TKI patients (median OS 15.1 months (95% C.I. 6.7-23.5) vs. 8.6 months (95% C.I. 5.6-11.7), p = 0.011) but not significantly superior ORR, DCR or TTP. Amongst patients who received single agent TKI and were naive to both sorafenib and lenvatinib, those who received lenvatinib had significantly superior DCR, TTP and OS compared to those who received sorafenib (DCR 51.5% vs 25.8%, p = 0.035; median TTP 6.3 months (95% C.I. 3.0-9.7) vs. 1.8 months (95% C.I. 0-3.6), p = 0.003; median OS 12.0 months (95% C.I. 7.0-17.0) vs. 5.9 months (95% C.I. 1.9-10.0), p = 0.008). 70.3% and 15.5% of all patients, and 77.1% and 15.6% of patients who received single agent TKI experienced all grade and grade ≥3 AEs respectively. The most common AEs were hand foot syndrome, skin rash and diarrhea. Conclusions: TKIs can achieve encouraging anti-tumour response and survival outcomes with acceptable safety in prior ICI-treated aHCC patients. Moreover, TKI-ICI combinations were associated with better survival than single agent TKIs. Notably, among patients who received single agent TKIs, lenvatinib had significantly better responses and survival results than sorafenib.

Abstract
272 Background: Atezolizumab-bevacizumab is the new standard of care for first-line treatment of advanced hepatocellular carcinoma (HCC). However, the optimal sequence of therapy after disease progression on atezolizumab-bevacizumab is unclear. Methods: This multinational, multicenter, retrospective study assessed clinical outcomes of patients with advanced HCC who received subsequent systemic therapy after progression on atezolizumab-bevacizumab in Korea, Hong Kong and Singapore between July 2016 and April 2019. Results: A total of 49 patients were included; the median age was 60 years (range, 3780) and 73.5% were male. All patients were classified as Child-Pugh A and Barcelona-Clinic Liver Cancer stage C. Multikinase inhibitors (MKIs), including sorafenib (n = 29), lenvatinib (n = 19), and cabozantinib (n = 1), were used as second-line therapy for all patients. The objective response rate (ORR) and disease control rate (DCR) were 6.1% and 63.3%, respectively, in all patients. With a median follow-up duration of 11.0 months, median progression-free survival (PFS) and overall survival (OS) were 3.4 months (95% confidence interval [CI] 1.84.9) and 14.7 months (95% CI 8.121.2) in all patients. Median PFS with lenvatinib was significantly longer than that with sorafenib (6.1 months vs. 2.5 months; P= 0.004), although there was no significant difference in median OS (16.6 months vs. 11.2 months; P= 0.347). Treatment-related adverse events (TRAEs) of any grade and grade 3 occurred in 42 (85.7%) and 8 (16.3%) of patients. Common TRAEs included hand-foot syndrome (HFS) (n = 26, 53.1%), fatigue (n = 14, 28.6%), hypertension (n = 14, 28.6%), and diarrhea (n = 12, 24.5%). Conclusions: Second-line treatment with MKIs, mostly sorafenib and lenvatinib, showed comparable efficacy and manageable toxicities in patients with advanced HCC after disease progression on atezolizumab-bevacizumab.

Abstract
Introduction Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-associated mortality globally. Immune-checkpoint blockade (ICB) is one of the systemic therapy options for HCC. However, response rates remain low, necessitating robust predictive biomarkers. In the present study, we examined the expression of CD38, a molecule involved in the immunosuppressive adenosinergic pathway, on immune cells present in the tumor microenvironment. We then investigated the association between CD38 and ICB treatment outcomes in advanced HCC. Methods Clinically annotated samples from 49 patients with advanced HCC treated with ICB were analyzed for CD38 expression using immunohistochemistry (IHC), multiplex immunohistochemistry/immunofluorescence (mIHC/IF) and multiplex cytokine analysis. Results IHC and mIHC/IF analyses revealed that higher intratumoral CD38+ cell proportion was strongly associated with improved response to ICB. The overall response rates to ICB was significantly higher among patients with high proportion of total CD38+cells compared with patients with low proportion (43.5% vs 3.9%, p=0.019). Higher responses seen among patients with a high intratumoral CD38+cell proportion translated to a longer median progression-free survival (mPFS, 8.21 months vs 1.64 months, p=0.0065) and median overall survival (mOS, 19.06 months vs 9.59 months, p=0.0295). Patients with high CD38+CD68+macrophage density had a better mOS of 34.43 months compared with 9.66 months in patients with low CD38+CD68+ macrophage density. CD38hi macrophages produce more interferon γ (IFN-γ) and related cytokines, which may explain its predictive value when treated with ICB. Conclusions A high proportion of CD38+ cells, determined by IHC, predicts response to ICB and is associated with superior mPFS and OS in advanced HCC.

Abstract
4590 Background: Nivolumab (N) and Y90-radioembolization (RE) are both therapeutic options in advanced hepatocellular carcinoma (aHCC). Increasing evidence suggests that radiotherapy synergizes with immune checkpoint inhibitors to augment anti-tumour effects. Methods: Eligible Child-Pugh A aHCC patients (pts) were treated with Y90-RE followed by N 240mg, 21 days after Y90-RE and every 2 weeks thereafter. Pre- and on-treatment tumor biopsies together with circulating biomarkers were obtained. Primary end-point was overall response rate (ORR) (per RECIST v 1.1). Overall response was defined as the composite overall response observed for the lesions within Y90-RE field and outside Y90-RE field. Key secondary end points included disease control rate (DCR), progression free survival (PFS), overall survival (OS), and safety. 36 evaluable pts were needed to assess whether the addition of N improved the ORR of Y90-RE from 21% to 41% as determined by Simon two-stage optimal design with 80% power and one sided significance level of 0.05. Results: Forty pts were enrolled of which 36 were evaluable. At baseline: 63.9% were HepB in aetiology; 63.9% BCLC stage C; 47.2% had AFP > 400ng/mL; number of liver lesions – median 5 (range 1- 20); size of largest liver lesion – median 80mm (range 14-177mm); 27.8% had prior TACE; and 13.9% had prior systemic therapy. ORR was 31% (95% CI 16.4 - 48.1%). Eight out of 11 responders had not progressed at study cut-off. DCR was 58.3%. 81% of target lesions within Y90-RE field regressed. With a median follow up of 16.4 months, median PFS and OS were 4.6 months (95% CI 2.3m - 8.4m) and 15.1 months (95% CI 7.8m - NE) respectively. Six- and 12-month PFS rates were 44.2% (95% CI 27.3% - 59.9%) and 26.1% (95% CI 11.2% - 43.8%) respectively. Overall, N+ Y90-RE was well tolerated and safe; only 11% had grade 3/4 treatment related adverse events (AEs). Responders demonstrated significant alterations of LIF, MIG and Eotaxin3 levels in the pre-treatment cytokine analyses. Conclusions: Combination N+Y90-RE resulted in an encouraging ORR of 31% (95% CI 16.4 - 48.1%) in aHCC. 81% of target lesions within Y90-RE field regressed suggesting synergy in combining Y90-RE with nivolumab. This combination is safe and tolerable with low G3/4 treatment related AEs of 11%. Further biomarker analyses will be presented at the meeting. Clinical trial information: NCT03033446 .

Abstract
559 Background: Immune checkpoint inhibitor (ICI) use in advanced hepatocellular carcinoma (HCC) is increasing. Real-world data on efficacy and safety however is lacking, more so when used in patients who fall out of standard clinical trial criteria. Methods: We conducted a retrospective review of all patients with advanced HCC seen at our centre who received at least one dose of an ICI between May 2015 - June 2018. Data cutoff was 31 Dec 2018. Responses were evaluated using RECIST v1.1 criteria. Results: 114 patients fulfilled inclusion criteria. Median age was 66 years and 88.6% were male. 96.5% had an ECOG PS of 0 – 1. 64.9% received an ICI within a clinical trial setting. 62.3% received monotherapy ICI. 19.6% of patients had Child-Pugh B disease on initiation of ICI, and 69.3% had an ALBI Grade of 2. 50.0% were known to have hepatitis B and 11.4% had hepatitis C. Baseline HBV VL ranged from undetectable to 8210000 IU/mL. 30.7% received prior systemic treatment, most commonly sorafenib (82.9%). Over a median follow-up duration of 5.7 months (0.03 - 42.4), ORR was 18.4%, and disease control rate (DCR) was 51.8%. Median PFS was 2.6 months (1.7 - 3.9), and median OS was 13.9 months (7.0 - 16.2). 5 patients (23.8%) had response duration of more than 18 months. 35.1% received further systemic therapy after ICI. On multivariable analyses, age ≥ 65 years, higher albumin level and lower bilirubin level were associated with increased OS. 68.0% of patients experienced adverse events (AEs) of any grade, 12.0% of these being grade 3 - 4. No grade 5 adverse events were observed. Use of antiviral therapy was associated with a lower risk of hepatic AEs (p = 0.04) whilst high baseline HBV VL was not associated with an increased risk of reactivation or hepatic AEs. Conclusions: In the real-world setting, responses and adverse event profiles to ICI use are comparable to those observed in clinical trials despite a more heterogenous population base. The expansion of indications for ICI use in advanced HCC beyond current approvals warrants greater study.

Abstract
Longitudinally extensive transverse myelitis (LETM) is most commonly associated with neuromyelitis optica spectrum disorders (NMOSD). However, a wide range of etiologies may produce longitudinally extensive spinal cord lesions (LESCLs) on imaging. We highlight the case of a patient with a spinal cord tumor whose imaging showed LESCL and was diagnosed with LETM. He did not respond to immunosuppression and subsequently developed a progressive and protracted clinical course. Thoracic cord biopsy performed 6 years after symptom onset showed primary spinal oligoastrocytoma. We discuss the features that should raise suspicion of a neoplasm in the context of LESCL and serve a reminder that not all LESCLs are inflammatory.
