    Abstract: 535 Background: This study aimed to evaluate the efficacy and safety of SHR-1210 (a humanized anti-programmed cell death receptor 1 antibody) plus gemcitabine and oxaliplatin (GEMOX) as first line treatment in patients (pts) with biliary tract cancer (BTC). Methods: This was a single-arm, single-center, exploratory trial, which included advanced BTC pts. Pts received SHR-1210 (3mg/kg, total dose ≤200mg, ivd, D1/2W) combined with gemcitabine (800 mg/m2, ivd, D1/2W) and oxaliplatin (85mg/m2, ivd, D2/2W). Combined chemotherapy lasted for no more than 12 cycles. Once chemotherapy intolerance occurred or at end of 12-cycle combined chemotherapy, pts with stable disease or objective response would continue to take SHR-1210 as single agent until disease progression or intolerable toxicity. The primary endpoint was the 6-month progression free survival (PFS) rate. Results: From February 2018 to April 2019, 37 eligible pts were enrolled. The median age was 64 (range 41-74) years, male/female was 70.3/29.7%, and bile duct cancer/gallbladder cancer was 59.5/40.5%. All 37 pts were included in the safety analysis. The overall AE incidence rate was 97.3%. The incidence of grade ≥3 AEs was 73.0%, which mainly included increased GGT (gammaglutamyltransferase, 18.9%), hypokalemia (18.9%), and fatigue (16.2%). Particularly, the incidence of fever is 73.0%, in which 2 pts experienced grade 3/4 fever. Among 36 evaluable pts, 19 pts got partial response (PR, 52.8%), 14 pts stable disease (SD, 38.9%), and 3 pts progressive disease (PD, 8.3%) at best. The primary endpoint 6-month PFS rate was 50.0% (95% CI 32.4-65.4), which indicated that the primary endpoint of the study was reached, and mPFS was 6.2 months (95% CI 4.2-7.1). The 12-month overall survival (OS) rate was 50.5% (95% CI 30.6-67.4), and mOS was 12.1 months (95% CI 8.0-NA). Conclusions: This study has reached the pre-defined primary endpoint with a high response rate. Predictive biomarker analysis was reported in another abstract. Further study is needed to validate the efficacy of this combination. Clinical trial information: NCT03486678.

    Abstract: 4092 Background: SHR1210 is a humanized anti-programmed cell death receptor 1 (PD-1) antibody. We conducted a single arm exploratory study to evaluate the efficacy and safety of SHR-1210 plus gemcitabine and oxaliplatin (GEMOX) as first line treatment in patients (pts) with biliary tract cancer (BTC). Methods: Pts received SHR-1210 (3mg/kg, total dose ≤200mg, ivd, D1/2W) combined with gemcitabine (800 mg/m2, ivd, D1/2W) and oxaliplatin (85mg/m2, ivd, D2/2W). Combined chemotherapy lasted for no more than 8-12 cycles. Once chemotherapy intolerance occurred or at end of 12-cycle combined chemotherapy, pts with stable disease or objective response would continue to take SHR-1210 as single agent until disease progression or intolerable toxicity. Response was assessed every 8 weeks. Results: From February 2018 to Dec 15, 2018, 32 eligible pts were recruited, and 27 pts who had been treated for more than 2 months were included in this analysis. Median age was 64 (range 47-75) years. 16 pts were bile duct cancer, while 11 pts were gallbladder cancer. 26 pts can be evaluated for efficacy. Twelve pts achieved partial response (46.15%), 12 pts stable disease (46.15%), and 2 pts progressive disease. Pts with gallbladder cancer had the trend of higher objective response (63.64% vs 33.33%, p = 0.23) than those with cholangiocarcinoma. 19 pts had tissue sample for next generation sequencing. Gallbladder cancer had the tendency of higher median tumor mutation burden (TMB) than cholangiocarcinoma (8.1mut/Mb vs 5.4mut/Mb, p=0.33). Pts with high TMB( 〉 8.6 mut/Mb, based on geenseeq BTC database) had significantly higher objective response than low TMB (100% vs 26%, p=0.0294). The most common grade ≥3 adverse events were nausea (18.52%),increased GGT (gammaglutamyltransferase,18.52%), hypokalemia(18.52%) and fatigue (18.52%). Conclusions: SHR-1210 plus GEMOX showed promising efficacy with tolerable adverse events for BTC pts. Gallbladder cancer pts seem to benefit more from this treatment. Tumor mutation burden may be a predictive factor for immunotherapy. Clinical trial information: NCT03486678.

    Abstract: e16146 Background: The synergic combination of anti-PD-1/PD-L1 and antiangiogenic agents has exhibited as an encourage treatment pattern in aHCC. Multi-targeted antiangiogenic TKIs, such as lenvatinib and sorafenib, are approved for 1st-line treatment of aHCC. Sintilimab, a novel selective anti-PD-1 monoclonal antibody, has demonstrated encouraging clinical activities in aHCC. The trial aims to explore the safety and efficacy of sintilimab plus anlotinib (a TKI against angiogenesis) in aHCC. Methods: This is a single-arm phase 2 study. Eligible Pts with aHCC, BCLC stage C or B (not amenable for surgery and chemoembolization), Child-Pugh scores≤7 and ECOG PS ≤ 1 received 1st-line treatment of sintilimab (200mg, iv, D1) plus anlotinib (12mg, po, QD, D1-14) every 3 wks until disease progression or unacceptable toxicity. Primary endpoints were safety and objective response rate (ORR, per RECIST 1.1), and secondary endpoints included disease control rate (DCR), progression free survival (PFS), duration of response (DOR) and overall survival (OS). Results: As of January 15, 2021, 20 pts were enrolled (males 18 ; median age 56 yrs [range 41-70] ; BCLCB/C: 5/15 ; Child-Pugh A/B7: 19/1 ; HBV infection 20). All pts received at least two cycles of treatments with median cycles 7.5 [range 2-22] . Median follow-up was 12 months [range 3-19]. The most common treatment-related adverse events (TRAEs) were grade 1-2 with thrombocytopenia (45.0%), hand-foot syndrome (40.0%), hypertension (35.0%), increased AST (35.0%), ALT (30.0%), decreased neutrophil count (25.0%), leukopenia (25.0%). 8 pts experienced manageable grade 3 TRAEs, and no grade 4/5. 12 pts required dose reduction of anlotinib (9 pts to 10 mg and 3 to 8 mg). No treatment withdraw caused by TRAEs. ORR was 40.0% (8/20) with 1 CR and 7 PR, 11 pts were SD, and DCR was 95.0% (19/20). Median DoR was not reached. 6m-PFS rate was 66.4% (95%CI: 47.7%-92.5%), immature median PFS was 14.65 months (95%CI: 5.06 -not reached) with 8 events. Conclusions: The combination of sintilimab and anlotinib showed promising clinical activities with manageable toxicity for first line treatment of aHCC. Clinical trial information: NCT04052152.

    Abstract: 536 Background: We conducted a trial to evaluate the efficacy and safety of SHR-1210 (a humanized anti-programmed cell death receptor 1 antibody) plus gemcitabine and oxaliplatin (GEMOX) as in untreated patients (pts) with biliary tract cancer (BTC) (NCT03486678). This study is to explore the predictive biomarkers for efficacy. Methods: Baseline lymphocyte count and lactate dehydrogenase (LDH) level were obtained from routine tests. Gene mutation and tumor mutation burden (TMB) from baseline tissue and blood samples were tested by the next generation sequencing (NGS) with a 425-gene panel. The expressions of PD-L1 and markers for lymphocyte, natural killer cells, and macrophages in baseline tumor tissue samples were analyzed by immunohistochemistry (IHC). Results: The median progression free survival (PFS) and overall survival (OS) in this trial was 6.2m and 12.1m, respectively. Firstly, pts with normal LDH level (≤271 U/L) had a tendency for longer PFS (6.2m vs 5.0m, p = 0.053) and significantly longer OS (p = 12.6m vs 6.8m, p 〈 0.001) than those with elevated LDH ( 〉 271 U/L). Low baseline lymphocyte count (≤ 1.1×10 9 /L) was related to worse OS (12.6m vs 6.9m, p 〈 0.001) and PFS (6.2m vs 3.9m, p = 0.021). Secondly, baseline tissue and ctDNA gene mutations were detected in 33 and 30 pts, respectively. Tissue analysis showed that pts with STK11 (p = 0.0254), CTNNB1 (p 〈 0.001) and SMARCA4 (p = 0.0181) wild type showed significantly longer PFS than those with mutations. Pts with ARID1A gene wild type showed a tendency for longer PFS (p = 0.0634) and significantly longer OS (p = 0.0149). Gene mutations from baseline ctDNA revealed that pts with wild type SMARCA4, CTNNB1, STK11, and NF1 had longer PFS than those with mutations. Lastly, IHC meant that PD-L1 positivity may be related to longer PFS (TPS 〉 1%, p = 0.08; IPS 〉 1%, p = 0.05). Besides, pts with CD68+ HLA-DR+ macrophages 〉 0.01%, CD68+ HLA-DR- macrophages 〉 2.5%, and CD56bright 〉 1.7% and CD56dim 〉 0.05 also got PFS benefits (all p 〈 0.05). TMB (cutoff = 7 muts/mbp) was not associated with PFS. Conclusions: Despite limited sample size, biomarkers from routine blood test, gene mutation and immune microenvironment can be helpful to stratify pts who are sensitive to immunotherapy in advanced BTC. Clinical trial information: NCT03486678.

    Abstract: Immune checkpoint inhibitors monotherapy has been studied in patients with advanced biliary tract cancer (BTC). The aim of this study was to assess the efficacy and safety of camrelizumab, plus gemcitabine and oxaliplatin (GEMOX) as first-line treatment in advanced BTC and explored the potential biomarkers associated with response. Methods In this single-arm, open-label, phase II study, we enrolled stage IV BTC patients. Participants received camrelizumab (3 mg/kg) plus gemcitabine (800 mg/m 2 ) and oxaliplatin (85 mg/m 2 ). Primary endpoints were 6-month progression-free survival (PFS) rate and safety. Secondary endpoints were objective response rate (ORR), PFS and overall survival (OS). Exploratory endpoints included association between response and tumor mutational burden (TMB), blood TMB, dynamic change of ctDNA and immune microenvironment. Results 54 patients with advanced BTC were screened, of whom 38 eligible patients were enrolled. One patient withdrew informed consent before first dose treatment. Median follow-up was 11.8 months. The 6-month PFS rate was 50% (95% CI 33 to 65). Twenty (54%) out of 37 patients had an objective response. The median PFS was 6.1 months and median OS was 11.8 months. The most common treatment-related adverse events (TRAEs) were fatigue (27 (73%)) and fever (27 (73%)). The most frequent grade 3 or worse TRAEs were hypokalemia (7 (19%)) and fatigue (6 (16%)). The ORR was 80% in patients with programmed cell death ligand-1 (PD-L1) tumor proportion score (TPS) ≥1% versus 53.8% in PD-L1 TPS 〈 1%. There was no association between response and TMB, blood TMB, immune proportion score or immune cells (p 〉 0.05), except that PFS was associated with blood TMB. Patients with positive post-treatment ctDNA had shorter PFS (p=0.007; HR, 2.83; 95% CI 1.27 to 6.28). Conclusion Camrelizumab plus GEMOX showed a promising antitumor activity and acceptable safety profile as first-line treatment in advanced BTC patients. Potential biomarkers are needed to identify patients who might respond to camrelizumab plus GEMOX. Trial registration number NCT03486678 .

    Abstract: Sleep-disordered breathing is a common disorder associated with significant morbidity. The genetic architecture of sleep-disordered breathing remains poorly understood. Through the NHLBI Trans-Omics for Precision Medicine (TOPMed) program, we performed the first whole-genome sequence analysis of sleep-disordered breathing. Methods The study sample was comprised of 7988 individuals of diverse ancestry. Common-variant and pathway analyses included an additional 13,257 individuals. We examined five complementary traits describing different aspects of sleep-disordered breathing: the apnea-hypopnea index, average oxyhemoglobin desaturation per event, average and minimum oxyhemoglobin saturation across the sleep episode, and the percentage of sleep with oxyhemoglobin saturation 〈  90%. We adjusted for age, sex, BMI, study, and family structure using MMSKAT and EMMAX mixed linear model approaches. Additional bioinformatics analyses were performed with MetaXcan, GIGSEA, and ReMap. Results We identified a multi-ethnic set-based rare-variant association ( p = 3.48 × 10 −8 ) on chromosome X with ARMCX3 . Additional rare-variant associations include ARMCX3-AS1 , MRPS33 , and C16orf90 . Novel common-variant loci were identified in the NRG1 and SLC45A2 regions, and previously associated loci in the IL18RAP and ATP2B4 regions were associated with novel phenotypes. Transcription factor binding site enrichment identified associations with genes implicated with respiratory and craniofacial traits. Additional analyses identified significantly associated pathways. Conclusions We have identified the first gene-based rare-variant associations with objectively measured sleep-disordered breathing traits. Our results increase the understanding of the genetic architecture of sleep-disordered breathing and highlight associations in genes that modulate lung development, inflammation, respiratory rhythmogenesis, and HIF1A -mediated hypoxic response.

    Abstract: Immune checkpoint inhibitors plus antiangiogenic tyrosine kinase inhibitors may offer a first-line treatment for advanced hepatocellular carcinoma (HCC). In this phase 2 trial [registered with clinicaltrials.gov (NCT04052152)], we investigated the safety and efficacy of first-line anti-PD-1 antibody sintilimab plus antiangiogenic TKI anlotinib for advanced HCC. Methods and Materials Pathologically-proven advanced HCC patients received sintilimab (200 mg) on day 1 and anlotinib (12 mg) once daily on days 1 to 14 every 3 weeks, with a safety run-in for the first six participants to assess dose-limiting toxicities (DLTs). The primary endpoints were safety and objective response rate (ORR) per RECIST v1.1. Results Twenty advanced HCC patients were enrolled. No DLTs occurred in the safety run-in. All patients had treatment-related adverse events (TRAEs). Grade 3 TRAEs occurred in 8 (40.0%) patients, the most common being decreased platelet count (10.0%) and increased γ-glutamyl transferase (10.0%). No grade 4/5 TRAEs occurred. Five (25%) patients developed immune-related AEs. The ORR was 35.0% (95%CI 15.4%-59.2%) per RECIST v1.1 and 55.0% (95%CI 31.5%-76.9%) per modified RECIST. At data cutoff (March 31, 2021), the median progression-free survival was 12.2 months (95%CI, 3.8 to not reached). The median PFS was significantly longer in patients with lower LDH levels (not reached [NR], 95% CI, 8.7 to NR vs. higher LDH levels 5.2 months, 95% CI 3.4 to NR; P =0.020) and a CONUT score ≤2 (NR, 95% CI 5.1 to NR vs. CONUT score & gt;2 6.2 months, 95% CI 1.8 to NR; P =0.020). Furthermore, patients showing tumor response had a significantly higher median proportion of CD16 + CD56 + NK cells than patients who had stable or progressive disease (21.6% vs. 14.6%; P=0.026). Conclusion Sintilimab plus anlotinib showed promising clinical activities with manageable toxicity as first-line treatment of advanced HCC.
