252 Background: Metabolic landscape evaluated by 18F-FDG positron emission tomography (PET) in advanced biliary tract cancer (BTC) has not been studied. Furthermore, the clinical meanings of metabolic features have rarely been reported. We evaluated the metabolic features using 18F-FDG PET and its clinical significances in advanced BTC. Methods: We consecutively enrolled advanced BTC patientswho underwent PET prior to palliative chemotherapy between 2003 and 2013. We retrospectively evaluated the findings of PET such as SUVmax, lesion numbers, involved organ and pathologic findings and other clinical factors including response to chemotherapy, progression-free survival (PFS) and overall survival (OS). Results: A total of 106 patients were enrolled (intrahepatic cholangiocarcinoma (ICC):53, extrahepatic BTC :7, gallbladder cancer (GB Ca) :30, and ampulla of vater cancer (AoV Ca): 16 patients) ECOG PS 0-1 in 89 and PS 2 in11 patients. 52.8 % of patients received gemcitabine-based chemotherapy and 47.1% of patients received 5-FU-based chemotherapy. The SUVmax was median 7.8 (range 0-44). Fifty-four percent of patients showed higher SUVmax in metastatic lesion than primary site. The SUVmax was different according to primary origin (ICC: 9.10, extrahepatic BTC: 5.90, GB Ca : 9.10, AoV Ca :6.37, p=0.008) and histologic differentiation (well-differentiated: 4.95, moderately-differentiated :6.60, poorly-differentiated :14.50, p=0.004) Patients with a SUVmax of >7.5 had more poorly differentiated histology and more PET uptake-lesions (p < 0.05) than those with a SUVmax of <7.5. The OS and PFS of all patients were 8.3 (95% CI: 5.7 – 10.8 ) and 4.9 months (95% CI: 3.4 – 6.3), respectively. Patients with a SUVmax of <7.5 had a significantly longer OS (11.4 vs. 7.4 months, p = 0.007) and PFS (6.6 vs. 4.3 months, p = 0.024) than those with a SUVmax of >7.5. In multivariate analysis, SUVmax was also a significant prognostic factor for OS (p=0.012) and PFS (p=0.039). Conclusions: Metabolic landscapes of advanced BTC are different according to primary origin and histology. This metabolic feature such as SUVmax could be a potential prognostic factor for OS and PFS in advanced BTC.

Pembrolizumab, an anti-programmed cell death (PD)-1 monoclonal antibody, is an anticancer agent showing substantial benefit in lung cancer and melanoma treatment. Biliary tract cancer (BTC) has been shown to respond to pembrolizumab; however, no credible data of such treatment outcomes exist. Therefore, we assessed the clinical outcomes and safety of pembrolizumab in patients with gemcitabine/cisplatin-refractory BTC. In this multicenter study, we retrospectively analyzed 51 patients with programmed cell death 1-ligand 1 (PD-L1)-positive gemcitabine/cisplatin-refractory BTC treated with pembrolizumab in four tertiary hospitals in Korea. PD-L1 positivity was defined as the expression of PD-L1 in ≥1% of tumor cells based on immunohistochemical staining (22C3, SP263, and E1L3N assays). The median age of the patients was 66 (range, 43–83) years and 29 (56.9%) were male. Extrahepatic cholangiocarcinoma was the most common cancer type (n = 30, 58.8%). Partial response and stable disease were achieved in 5 (9.8%) and 13 (25.5%) patients, respectively. Median progression-free survival and overall survival were 2.1 (95% CI, 1.7–2.4) and 6.9 (95% CI, 5.4–8.3) months, respectively. Overall, 30 (58.8%) patients experienced treatment-related adverse events (AEs). Only four (7.8%) patients experienced grades 3 and 4 AEs. In PD-L1-positive gemcitabine/cisplatin-refractory BTC, pembrolizumab presented durable efficacy, with a 9.8% response rate and manageable toxicity.

4625 Background: Patients (Pts) with unresectable or metastatic biliary tract cancer (BTC) and gallbladder cancer (GBC) have a poor prognosis. Vascular endothelial growth factor (VEGF) expression has been detected in BTC and GBC. Increased angiogenesis has been correlated with advanced stage of disease and poor prognosis. Given reported activity of gemcitabine (GEM) and oxaliplatin (OX) in BTC/GBC and potential benefits of targeting the VEGF pathway with bevacizumab (B), we performed a study to examine the efficacy and tolerability of GEM, OX and B (GEMOX-B) in unresectable or metastatic BTC/GBC. Methods: Eligibility criteria included unresectable or metastatic measurable BTC/GBC, 0–1 prior chemotherapy regimens, performance status = 2, and adequate organ function. No clinically significant cardiovascular disease or history of active bleeding. Pts were treated with all 3 drugs intravenously on days 1 and 15 every 28 days (one cycle): B was given first at 10 mg/kg, followed by GEM at 1000 mg/m2 as dose rate infusion at 10 mg/m2/minute, and OX at 85 mg/m2. Whole body FDG-PET scan was obtained at baseline and after cycle 2. The primary endpoint of the study was progression-free survival (PFS). Results: 19 pts (10 BTC and 9 GBC) have been enrolled since May 17, 2006: median age = 69 (25–82), M/F = 13/6, ECOG 0/1/2 = 7/10/2. Treatment has been well tolerated with no grade 4–5 toxicities seen. Treatment related grade 3 toxicities included (number of pts): hypertension (2), neutropenia (1), transient SGPT elevation (1), proteinuria (1), neuropathy (1), and fatigue (1). Of 11 pts followed for at least 4 months, 3 had confirmed partial responses (PR), 5 had stable disease (SD) of at least 4 cycles, and 3 had progressive disease (PD) per RECIST criteria. Five pts had more than 50% decrease in CA19–9 levels. Of 16 PET studies analyzed, changes in SUV values from baseline to after 2 cycles of treatment were: 11 PRs, 4 SDs, 1 PD per EORTC criteria. Conclusions: GEMOX-B can be safely administered with tolerable safety profiles in patients with advanced BTC/GBC. Early evidence of antitumor activity was seen. A decreased SUV in FDG-PET following GEMOX-B treatment was observed in the majority of patients. No significant financial relationships to disclose.

357 Background: Gemcitabine plus cisplatin (GP) is the standard first line chemotherapy for patients with advanced biliary tract cancer (BTC). In the pivotal ABC-02 study, patients received up to 24 weeks (6-8 cycles) of three-weekly GP. In daily practice setting, however, patients without progression often receive GP more than 6-8 cycles. It is uncertain whether maintenance treatment has clinical benefit in patients without progression on GP. Methods: Advanced BTC patients treated with GP between April 2010 and February 2015 in Asan Medical Center, Seoul, Korea, were retrospectively analyzed. Among the patients who did not progressed and stopped GP after 6-8 cycles, patients were stratified according to the further treatment; those with or without further cycles of GP (maintenance group vs observation group). Primary endpoint was overall survival (OS). Results: Among 740 patients, 231 patients (31.2%) were eligible for this analysis; 111 for observation group, 120 for maintenance group. In observation group, 76 patients (68.5%) stopped GP due to completion of scheduled chemotherapy and 27 patients (24.3%) due to the patients’ request or toxicity. There were no statistically significant differences in baseline characteristics between two groups. Median OS from the initiation of GP was 20.5 months [95% CI 15.4-25.6] and 22.4 months [95% CI 17.0-27.8] in the observation and maintenance group, respectively (p = 0.32). Median progression-free survival (PFS) was 10.4 months [95% CI 7.0-13.8] and 13.2 months [95% CI 11.3-15.2], respectively (p = 0.22). These were consistent in the multivariate analyses for OS and PFS after the adjustment of prognostic factors. Conclusions: In our analysis, maintenance therapy of GP was not associated with improved survival outcomes. Considering the potential disadvantages such as cumulative toxicities, maintenance therapy may not be beneficial in patients who did not progressed on 6-8 cycles of GP.

e16679 Background: Biliary tract cancer (BTC) is associated with poor prognosis because of its aggressive and heterogeneous nature. Programmed death ligand 1 (PD-L1) has been considered as a novel biomarker for prognosis and response of immune checkpoint inhibitors in various tumors. However, there are limited data reporting on the role of PD-L1 in advanced BTC patients. Methods: We analyzed 186 patients with advanced BTC who received palliative gemcitabine and platinum between May 2010 and December 2019. All patients were evaluated for PD-L1 expression by combined positive score (CPS) positivity. Results: In all 186 patients, the median age was 62 years (range 38-82), and the primary tumor location was intrahepatic cholangiocarcinoma (IH-CCC) in 72 patients (38.7%), extrahepatic (EH)-CCC in 90 (48.4%), and gallbladder (GB) cancer in 24 (12.9%). There were 158 (84.9%) patients with recurrent disease and 28 (15.1%) with metastatic disease. Among the 186 patients, 53 (28.5%) had PD-L1 CPS positivity, and 133 were CPS negative. The median overall survival (OS) of patients with PD-L1 CPS positivity or negativity was 12.1 and 15.4 months, respectively. The median progression-free survival (PFS) in patients with PD-L1 positivity or negativity was 5.7 and 7.1 months, respectively. The OS and PFS were not statistically different between groups. In sub-group analysis, EH-CCC patients with PD-L1 negativity had more favorable OS (17.2 vs. 11.6 months, p= 0.002) and PFS (7.8 vs. 5.4 months, p= 0.005) than those that were PD-L1 negative. However, this finding was not reproduced in patients with IH-CCC or GB cancer. Univariate analysis of the association between PD-L1 expression and OS in patients with advanced BTC indicated that PD-L1 CPS positivity has a prognostic role in sub-populations older than 60 years (HR 1.743, CI 1.001-3.034, p = 0.050), those with EH-CCC (HR 2.449, CI 1.355-4.426, p = 0.003), and those with liver metastasis (HR 2.511, CI 1.362-4.626, p = 0.003). Conclusions: This study demonstrated that PD-L1 expression might be a novel prognostic biomarker in patients with EH-CCC but not for patients with IH-CCC or GB cancer.

Background: High tumor mutational burden (TMB-H) has been reported as a predictive marker to immunotherapy or prognostic marker in various tumor types. However, there has been little study of the role of TMB-H in advanced biliary tract cancer (BTC). Methods: We analyzed 119 advanced BTC patients who received Gemcitabine/Cisplatin (GP) as a first-line treatment between November 2019 and April 2021. Next-generation sequencing (NGS), including TMB analysis, as a routine clinical practice was performed in 119 patients. The TruSightTM Oncology 500 assay from Illumina was used as a cancer panel. Results: Among 119 patients, 18 (18.5%) had a tumor with high TMB (≥ 10 Muts/Mb). There were no significant differences between the status of TMB and clinical outcomes with GP, including objective response rate (ORR) ( P = .126), disease control rate (DCR) ( p = .454), and median progression-free survival (PFS) ( p = .599). The median overall survival (OS) was not different between patients with TMB-H and no TMB-H ( p = .430). In subgroup analysis of 32 patients receiving immune checkpoint inhibitor (ICIs), there were significant differences in ORR ( p = .034) and median PFS ( p  = .025) with ICIs between patients with and without TMB-H. Conclusions: This study revealed that TMB-H in advanced BTCs did not have a prognostic or role in the standard first-line treatment. However, TMB-H might be a predictive biomarker for response to ICIs in advanced BTC.

Purpose The current standard chemotherapy for advanced biliary tract cancer (BTC) has limited benefit, and novel therapies need to be investigated. Materials and MethodsIn this prospective cohort study, programmed death ligand-1 (PD-L1)–positive BTC patients who progressed on first-line gemcitabine plus cisplatin were enrolled. Pembrolizumab 200 mg was administered intravenously every 3 weeks. ResultsBetween May 2018 and February 2019, 40 patients were enrolled. Pembrolizumab was given as second-line (47.5%) or ≥ third-line therapy (52.5%). The objective response rate was 10% and 12.5% by Response Evaluation Criteria in Solid Tumor (RECIST) v1.1 and immune- modified RECIST (imRECIST) and median duration of response was 6.3 months. Among patients with progressive disease as best response, one patient (1/20, 5.0%) achieved complete response subsequently. The median progression-free survival (PFS) and overall survival (OS) were 1.5 months (95% confidence interval [CI], 0.0 to 3.0) and 4.3 months (95% CI, 3.5 to 5.1), respectively, and objective response per imRECIST was significantly associated with PFS (p < 0.001) and OS (p=0.001). Tumor proportion score ≥ 50% was significantly associated with higher response rates including the response after pseudoprogression (vs. < 50%; 37.5% vs. 6.5%; p=0.049). Conclusion Pembrolizumab showed modest anti-tumor activity in heavily pretreated PD-L1–positive BTC patients. In patients who showed objective response, durable response could be achieved.

Abstract Background Evidence for the efficacy of immunotherapy in biliary tract cancer (BTC) is limited and unsatisfactory. Methods Chinese BTC patients receiving a PD-1 inhibitor with chemotherapy, PD-1 inhibitor monotherapy or chemotherapy alone were retrospectively analyzed. The primary outcome was overall survival (OS). The key secondary outcomes were progression-free survival (PFS) and safety. Patients previously treated with any agent targeting T cell costimulation or immune checkpoints were excluded. Results The study included 77 patients (a PD-1 inhibitor plus chemotherapy, n = 38; PD-1 inhibitor monotherapy, n = 20; chemotherapy alone, n = 19). The median OS was 14.9 months with a PD-1 inhibitor plus chemotherapy, significantly longer than the 4.1 months with PD-1 inhibitor monotherapy (HR 0.37, 95% CI 0.17–0.80, P = 0.001) and the 6.0 months with chemotherapy alone (HR 0.63, 95% CI 0.42–0.94, P = 0.011). The median PFS was 5.1 months with a PD-1 inhibitor plus chemotherapy, significantly longer than the 2.2 months with PD-1 inhibitor monotherapy (HR 0.59, 95% CI 0.31–1.10, P = 0.014) and the 2.4 months with chemotherapy alone (HR 0.61, 95% CI 0.45–0.83, P = 0.003). Grade 3 or 4 treatment-related adverse events were similar between the anti-PD-1 combination group and the chemotherapy alone group (34.2% and 36.8%, respectively). Conclusions Anti-PD-1 therapy plus chemotherapy is an effective and tolerable approach for advanced BTC.

This study is an investigator-initiated randomized phase II trial focusing on the treatment of advanced biliary tract cancer with either oxaliplatin 50 mg/m2 and gemcitabine 1000 mg/m2 on day 1 in a two-week cycle with capecitabine 650 mg/m2 twice-daily continuously or cisplatin 25 mg/m2 and gemcitabine 1000 mg/m2 on day 1 and day 8 in a three-week cycle. One-hundred patients were included. Forty-seven patients received oxaliplatin, gemcitabine, and capecitabine with a median progression-free survival (mPFS) of 5.7 months (95% CI 3.0–7.8) and a median overall survival (mOS) of 8.7 months (95% CI 6.5–11.2). Forty-nine patients received cisplatin and gemcitabine with a mPFS of 7.3 months (95% CI 6.0–8.7) and a mOS of 12.0 months (95% CI 8.3–16.7). This trial confirms a mOS of 12 months with cisplatin and gemcitabine, as found in earlier trials. With a superior tumor control rate of 79% vs. 60% (p = 0.045), a difference in the mPFS of 1.6 months (HR = 0.721, p = 0.1), and a difference in the mOS of 3.3 months (HR = 0.731, p = 0.1), cisplatin and gemcitabine should still be considered the standard first-line treatment for advanced biliary tract cancer.

Gemcitabine/cisplatin is standard of care for first-line treatment of patients with advanced biliary tract cancer (aBTC); new treatments are needed. NUC-1031 is designed to overcome key cancer resistance mechanisms associated with gemcitabine. The tolerability/efficacy signal of NUC-1031/cisplatin in the Phase Ib ABC-08 study suggested that this combination may represent a more efficacious therapy than gemcitabine/cisplatin for patients with aBTC, leading to initiation of the global NuTide:121 study which will include 828 patients ≥18 years with untreated histologically/cytologically-confirmed aBTC (including cholangiocarcinoma, gallbladder or ampullary cancer); randomized (1:1) to NUC-1031 (725 mg/m2)/cisplatin (25 mg/m2) or gemcitabine (1000 mg/m2)/cisplatin (25 mg/m2), on days 1/8, Q21-days. Primary objectives are overall survival and objective response rate. Secondary objectives: progression-free survival, safety, pharmacokinetics, patient-reported quality of life and correlative studies.
