A phase II open-label, single-center, nonrandomized trial of Y90-radioembolization in combination with nivolumab in Asian patients with advanced hepatocellular carcinoma: CA 209-678.

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 Background This open-label, Phase 1b/2 study evaluated the highly selective MET inhibitor tepotinib in systemic anticancer treatment (SACT)-naive Asian patients with advanced hepatocellular carcinoma (aHCC) with MET overexpression. Methods In Phase 2b, tepotinib was orally administered once daily (300, 500 or 1,000 mg) to Asian adults with aHCC. The primary endpoints were dose-limiting toxicities (DLTs) and adverse events (AEs). Phase 2 randomised SACT-naive Asian adults with aHCC with MET overexpression to tepotinib (recommended Phase 2 dose [RP2D]) or sorafenib 400 mg twice daily. The primary endpoint was independently assessed time to progression (TTP). Results In Phase 1b (n = 27), no DLTs occurred; the RP2D was 500 mg. In Phase 2 (n = 90, 45 patients per arm), the primary endpoint was met: independently assessed TTP was significantly longer with tepotinib versus sorafenib (median 2.9 versus 1.4 months, HR = 0.42, 90% confidence interval: 0.26–0.70, P = 0.0043). Progression-free survival and objective response also favoured tepotinib. Treatment-related Grade ≥3 AE rates were 28.9% with tepotinib and 45.5% with sorafenib. Conclusions Tepotinib improved TTP versus sorafenib and was generally well tolerated in SACT-naive Asian patients with aHCC with MET overexpression.

Objectives: Previously, no therapeutic agent has been known to improve the overall survival compared with placebo in patients with hepatocellular carcinoma (HCC), who have progressed after sorafenib. In this patient population, regorafenib was first demonstrated to confer a survival benefit in the RESORCE trial, and subsequently it was approved as a second-line treatment for patients with advanced HCC. An open-label expanded access program (EAP) of regorafenib was implemented for compassionate use. We investigated the efficacy and safety of regorafenib based on our experience of the RESORCE trial and the EAP. Methods: Data from 5 patients from the RESORCE trial and 6 from the EAP were analyzed retrospectively. All patients had tolerated prior sorafenib and were progressing during sorafenib treatment. Results: The median progression-free survival was 9.2 months (95% CI 2.3-16.1). One patient achieved a partial response and 7 achieved stable disease. The objective response rate was 9.1%, and the disease control rate was 72.7%. No treatment-associated mortalities were observed. Grade 3 hypophosphatemia was observed in 2 patients, grade 2 anorexia was observed in 5 patients, and grade 3 neutropenia was observed in 2 patients. Grade 2 and grade 3 thrombocytopenia were observed in 2 and 3 patients, respectively. All treatment-related adverse events were improved by reduction or interruption of regorafenib. Five patients showed decreased serum albumin levels. Conclusion: Sorafenib and regorafenib sequential therapy presents a safe and effective treatment option for patients with advanced HCC.

Introduction/Objective: Lenvatinib demonstrated efficacy and safety in patients with advanced hepatocellular carcinoma (HCC) in the randomized phase III REFLECT trial. Considering the discrepancies in patients between clinical trial data and daily practice, an account of practical experience is needed. Methods: We conducted a multicenter retrospective analysis in which 3 tertiary referral centers participated. A total of 92 patients with advanced HCC treated with lenvatinib between September 2018 and January 2020 were analyzed. Results: Lenvatinib was used as the first-line therapy for 67 (72.8%) patients, and for 25 (27.2%) patients previously treated with other systemic therapy including immune checkpoint inhibitors. At the time of initiation of lenvatinib, 74 (80.4%) and 18 (19.6%) patients were classified as Child-Pugh A and B, respectively. Thirty-five patients (38.0%) had extensive disease that would have excluded them from the REFLECT trial. In the Child-Pugh A group, the response rate graded according to the Response Evaluation Criteria in Solid Tumors v1.1 was 21.1%, median progression-free survival (PFS) was 4.6 (95% confidence interval [CI] 3.1–6.1) months, and overall survival (OS) was 10.7 (95% CI 4.8–16.5) months for patients treated with first-line lenvatinib (n = 57). With second- or later-line lenvatinib (n = 17), median PFS and OS were 4.1 (95% CI 3.1–5.1) and 6.4 (95% CI 5.1–7.7) months, respectively. In the Child-Pugh B group (n = 18), median PFS and OS were 2.6 (95% CI 0.6–4.6) and 5.3 (95% CI 2.0–8.5) months, respectively. The most common grade 3–4 toxicities were hyperbilirubinemia (n = 8; 8.7%), AST elevation (n = 6; 6.5%), and diarrhea (n = 5; 5.4%) across all study patients. Conclusions: In this real-world study, lenvatinib was found to be well tolerated and effective in more heterogeneous HCC patient populations.

End Point

Purpose To determine whether FOLFOX4 (infusional fluorouracil, leucovorin, and oxaliplatin) administered as palliative chemotherapy to patients with advanced hepatocellular carcinoma (HCC) provides a survival benefit and efficacy versus doxorubicin. Patients and Methods This multicenter, open-label, randomized, phase III study in mainland China, Taiwan, Korea, and Thailand involved 371 patients age 18 to 75 years who had locally advanced or metastatic HCC and were ineligible for curative resection or local treatment. They were randomly assigned at a ratio of one to one to receive either FOLFOX4 (n = 184) or doxorubicin (n = 187). The primary end point was overall survival (OS); secondary end points included progression-free survival (PFS), response rate (RR) by RECIST (version 1.0), and safety. Results At the prespecified final analysis, median OS was 6.40 months with FOLFOX4 (95% CI, 5.30 to 7.03) and 4.97 months with doxorubicin (95% CI, 4.23 to 6.03; P = .07; hazard ratio [HR], 0.80; 95% CI, 0.63 to 1.02). Median PFS was 2.93 months with FOLFOX4 (95% CI, 2.43 to 3.53), and 1.77 months with doxorubicin (95% CI, 1.63 to 2.30; P < .001; HR, 0.62; 95% CI, 0.49 to 0.79). RR was 8.15% with FOLFOX4 and 2.67% with doxorubicin (P = .02). On continued follow-up, the trend toward increased OS with FOLFOX4 was maintained (P = .04; HR, 0.79; 95% CI, 0.63 to 0.99). Toxicity was consistent with previous experiences with FOLFOX4; proportions of grade 3 to 4 adverse events were similar between treatments. Conclusion Although the study did not meet its primary end point, the trend toward improved OS with FOLFOX4, along with increased PFS and RR, suggests that this regimen may confer some benefit to Asian patients, but an OS benefit cannot be concluded from these data.

Objective: REACH-2 and REACH were randomized, placebo-controlled, double-blind, multicenter phase 3 trials which showed survival benefits of ramucirumab treatment in patients with advanced hepatocellular carcinoma (HCC) and elevated alpha-fetoprotein (AFP). We evaluated the efficacy and safety of ramucirumab in Asian and non-Asian patients with AFP ≥400 ng/mL from REACH-2 and REACH. Methods: We pooled Asian and non-Asian patients from the REACH-2 and REACH trials and performed an individual patient data meta-analysis. Overall survival (OS) and progression-free survival were evaluated using the Kaplan-Meier method. Hazard ratios (HRs) were estimated with a stratified Cox regression model. Results: In the pooled REACH-2 and REACH patient population, 291 Asian patients were randomly assigned to receive ramucirumab (n = 168) or placebo (n = 123), and 251 non-Asian patients received ramucirumab (n = 148) or placebo (n = 103). The median OS was significantly longer in the ramucirumab arm in comparison to the placebo arm for Asian patients (8.08 vs. 4.76 months, stratified HR 0.73 [95% CI 0.56–0.95], p = 0.0189) and non-Asian patients (7.98 vs. 5.22 months, stratified HR 0.65 [95% CI 0.49–0.86], p = 0.0028). The overall response rate (ORR) and disease control rate (DCR) were significantly higher in the ramucirumab arm compared to the placebo arm for Asian patients (ORR: 4.2 vs. 0.8%; DCR: 53.6 vs. 33.3%) and non-Asian patients (ORR: 6.8 vs. 1.0%; DCR: 59.5 vs. 41.7%). The most common grade ≥3 treatment-emergent adverse events reported in the ramucirumab arm were hypertension (7.7%), decreased appetite (1.2%), and ascites (1.2%) for Asian patients and hypertension (16.9%), ascites (8.8%), asthenia (4.7%), and fatigue (5.4%) for non-Asian patients. Discussion and Conclusion: This pooled analysis of the REACH-2/REACH trials demonstrates significant benefits, with a manageable safety profile, of ramucirumab treatment in Asian and non-Asian patients with advanced HCC and baseline AFP ≥400 ng/mL.

Introduction: KEYNOTE-240 investigated the efficacy and safety of pembrolizumab plus best supportive care (BSC) in sorafenib-treated patients with advanced hepatocellular carcinoma (HCC). Results for the subgroup of patients from Asia are described. Methods: Adults with advanced HCC previously treated with sorafenib were randomized 2:1 to pembrolizumab or placebo plus BSC. Here, the Asian subgroup comprised patients enrolled in Hong Kong, Japan, Korea, the Philippines, Taiwan, and Thailand. Primary endpoints were progression-free survival (PFS) per blinded central imaging review and overall survival (OS). Secondary endpoints included objective response rate (ORR) per blinded central imaging review, duration of response (DOR), and safety. Results: The Asian subgroup included 157 patients. As of January 2, 2019, the median follow-up in this subgroup was 13.8 months for pembrolizumab and 8.3 months for placebo. The median PFS was 2.8 months for pembrolizumab (95% confidence interval [CI] 2.6–4.1) versus 1.4 months (95% CI 1.4–2.4) for placebo (hazard ratio [HR] 0.48; 95% CI 0.32–0.70). The median OS was 13.8 months (95% CI 10.1–16.9) for pembrolizumab versus 8.3 months (95% CI 6.3–11.8) for placebo (HR 0.55; 95% CI 0.37–0.80). ORR was 20.6% (95% CI 13.4–29.5) for pembrolizumab versus 2.0% (95% CI 0.1–10.6) for placebo (difference: 18.5%; 95% CI 8.3–27.6). The median DOR was 8.6 and 2.8 months for pembrolizumab and placebo, respectively. Any grade treatment-related adverse events (TRAEs) occurred in 63 patients (58.9%) receiving pembrolizumab and 24 patients (48.0%) receiving placebo; 14 (13.1%) and 2 (4.0%) patients experienced grade 3–5 TRAEs, respectively. No treatment-related deaths occurred. Conclusion: Pembrolizumab demonstrated antitumor activity and was well tolerated in the Asian subgroup of KEYNOTE-240. A trend toward greater benefit with pembrolizumab in the Asian subgroup was observed compared with the overall cohort, supporting further evaluation of pembrolizumab treatment in this population.

New Strategy

BackgroundNivolumab and pembrolizumab disrupt the programmed cell death-1 immune checkpoint and display promising efficacy and safety results in advanced hepatocellular carcinoma (HCC). However, the benefits remain limited. The preliminary results of lenvatinib (LEN) combined with immune checkpoint inhibitors (ICIs) reveal that the combinations were well-tolerated and encouraging. This study aimed to analyze the safety and efficacy of LEN plus ICIs in a real-world cohort of patients with advanced HCC.MethodBetween June 4, 2017, and June 30, 2019, 16 patients received LEN plus nivolumab, and 13 patients were treated with LEN plus pembrolizumab, with the confirmed advanced HCC retrospectively analyzed. The clinical parameters, as well as the outcomes, were assessed.ResultsAll the patients had Barcelona Clinical Liver Cancer Stage C. LEN with ICIs was used as systemic second-, third-, and fourth-line treatments in seven (24.1%), 14 (48.3%), and eight (27.6%) patients, respectively. At the time of data cutoff, six patients (37.5%) were still receiving LEN with nivolumab, while another six patients (46.2%) were still receiving LEN with pembrolizumab. An objective response was recorded in seven patients (25.9%), while the best overall responses were from one complete response and six partial responses. The 6- and 12-month over survival (OS) rates were 62.6% and 53.7%, respectively. Furthermore, the 6- and 12-month progression-free survival (PFS) rates were 43.5% and 31.8%, respectively. In the subgroup analyses, the 6- and 12-month OS and PFS rates for patients treated with LEN plus nivolumab were 62.5% and 52.1%, respectively, and 43.8% and 30.0%, respectively. The 6- and 12-month OS and PFS rates for patients treated with LEN plus pembrolizumab were 51.3% and 51.3%, respectively, and 49.2% and 49.2%, respectively. A total of 11 (31%) deaths were reported in this study, four of which were attributed to grade 5 adverse events presented as fatal treatment-related hepatitis.ConclusionThe combination of LEN and ICIs is a promising new strategy for the treatment of HCC patients. However, high-grade hepatic toxicity was observed and further evaluation of this combination is still required.

Abstract Purpose: This study aimed to assess efficacy and safety of anlotinib as a first- or second-line treatment for advanced or metastatic hepatocellular carcinoma (aHCC) and to identify the predictive plasma cytokines on efficacy of anlotinib.Methods: It was a phase II clinical study. Patients with aHCC were recruited from October 2016 to April 2019 and divided into two cohorts according to previous tyrosine kinase inhibitors (TKIs) therapy. Those without or with prior TKIs were in Cohort 1 or 2, respectively. All patients took anlotinib (12mg/day, Day1–14, three weeks per cycle). The primary endpoint was 12-week progression free survival (PFS) rate. Relationship between series plasma cytokine level and efficacy of anlotinib was analyzed.Results: Enrolled 26 patients in Cohort 1 and 24 in Cohort 2. In Cohort 1, the 12-week PFS rate was 80.8% (95% confidence interval [CI]; 59.8%–91.5%) and median time to progression (TTP) was 5.9 months (95% CI; 4.8–6.9). In Cohort 2, the 12-week PFS rate and median TTP was 72.5% (95% CI; 48.7%–86.6%) and 4.6 months (95% CI; 2.7–10.0), respectively. The median TTP on patients with baseline plasma level of CXCL1 (C-X-C motif chemokine ligand 1) less than 7.6 ng/μl was significant longer in both cohorts. The most common grade 3–5 adverse events were hypertension (8%), diarrhea (8%) and hand-foot syndrome (6%). Conclusion: Anlotinib showed promising efficacy and safety as a first- or second-line treatment with a continuous TKIs treatment strategy in aHCC. The plasma CXCL1 might be a predictor for efficacy of anlotinib.

4007 Background: Cabozantinib (cabo) is an oral, potent inhibitor of MET and VEGFR2. MET over-expression has been observed in advanced hepatocellular carcinoma (HCC). Anti-VEGF pathway agents have shown clinical benefit in pts w/ HCC. Simultaneous targeting of the MET and VEGF signaling pathways with cabo may therefore be a promising treatment strategy. Methods: Eligible HCC patients (pts) were required to have measurable disease per RECIST, ≤ 1 prior systemic regimen and Child-Pugh score of A. Pts received cabo at 100 mg qd over a 12 wk Lead-in stage. Tumor response (mRECIST) was assessed q6 wks. Treatment ≥ wk 12 was based on response: pts with PR continued open-label cabo, pts with SD were randomized to cabo vs placebo, and pts with PD discontinued. Primary endpoint in the randomized phase was progression free survival (PFS). The primary endpoint was overall response rate (RR) per mRECIST in the Lead-in stage. Results: Enrollment has been completed (n = 41); all pts are unblinded. Median age: 61 years (33 to 83). Males: 76%; Asian: 37%. HCC etiology: Hep B 24%; Hep C 22%; alcohol abuse 20%; other 38%. Extra-hepatic spread observed in 70%. Median number of prior systemic treatments was 1; prior sorafenib was 51%. Median baseline AFP was 368 ng/mL (3 – 259,298); 86% had elevated AFP at baseline. Median follow-up was 5.5 mos (0.8 -18.5). 29 pts (71%) completed the Lead-in stage. Median PFS from Study Day 1 was 4.2 mos. 2/36 pts evaluable for tumor assessment at 12 weeks achieved a confirmed PR (cPR) by original RECIST (RR 5%). One more pt randomized at Week 12 achieved a cPR at 18 weeks. 28/36 pts (78%) with ≥1 post-baseline scan had tumor regression (with no apparent relationship to prior sorafenib therapy). The overall disease control rate (DCR = PR+SD) at Week 12: was 68% (Asian subgroup: 73%). AFP responses (defined as reduction from baseline of >50% in pts with elevated AFP at baseline) in 26 pts with ≥1 post-baseline result: 10/26 (38%). Most common Gr 3/4 AEs: diarrhea (17%), palmar-plantar erythrodyesthesia (15%), and thrombocytopenia (10%). Conclusions: Cabo treatment exhibits activity in HCC pts regardless of prior sorafenib treatment. The safety profile was comparable to that of other VEGFR TKIs.

TPS4658 Background: Portal vein tumor thrombosis (PVTT) is common among advanced hepatocellular carcinoma ( HCC), resulting in poor prognosis. As the standard first-line treatment, the efficacy of Sorafenib is not satisfactory in HCC with PVTT. Although immune checkpoint inhibitors have made a breakthrough in treatment of advanced HCC, objective response rate (ORR) of anti-PD-1 monoclonal antibody monotherapy is only 17-20%. Recently, PD-1/PD-L1 inhibitors combined with anti-angiogenesis therapy have shown good efficacy in the clinical studies. However, the data on immunotherapy for HCC with PVTT are still limited. Toripalimab is the first Chinese-produced anti-PD-1 monoclonal antibody marketed. We designed the study to evaluate the efficacy and safety of Sorafenib plus Toripalimab as the first-line treatment for unresectable HCC with PVTT. Methods: The study is a multicenter, single-arm, phase Ib/II trial. The primary objectives are 6-month progression-free survival (PFS) rate and safety. Secondary objectives include ORR, disease control rate, PFS, overall survival. The escalation stage includes two dose cohorts: Sorafenib 400 mg po qd or 400 mg bid combined with Toripalimab 240 mg iv d1 q3w. 6-12 patients are estimated to evaluate the dose-limiting toxicity within the first 42 days of administration. In the expansion stage, patients are treated with the recommended dose based on the escalation stage, until progressive disease or intolerable toxicity. Assuming Sorafenib plus Toripalimab can improve the 6-month PFS rate to 40% (Sorafenib:20%, β = 0.2, α = 0.05) and dropout is 10%, this stage need 39 patients. A total of 45-51 patients are enrolled. Major eligibility requirements include: unresectable HCC with diagnoses confirmed histologically or cytologically, or confirmed clinically in accordance with Chinese guideline for HCC diagnosis and treatment (v2017); radiographic evidence of PVTT; age ≥18 and < 75 years; at least one measurable lesion according to RECIST 1.1; a predicted life expectancy ≥ 3 months; ECOG PS≤1, Child-Pugh class A or B (≤7); no any prior systemic anti-cancer treatment; adequate organ function. Patients with hepatitis B treated with antiviral therapy (viral load < 100 IU/mL) or patients with chronic hepatitis C can be included. The study is open and actively enrolling at time of submission.
