Phase Ib Study of Lenvatinib Plus Pembrolizumab in Patients With Unresectable Hepatocellular Carcinoma.

ABSTRACT:

Purpose

The immunomodulatory effect of lenvatinib (a multikinase inhibitor) on tumor microenvironments may contribute to antitumor activity when combined with programmed death receptor-1 (PD-1) signaling inhibitors in hepatocellular carcinoma (HCC). We report results from a phase Ib study of lenvatinib plus pembrolizumab (an anti-PD-1 antibody) in unresectable HCC (uHCC).

Patients and methods

In this open-label multicenter study, patients with uHCC received lenvatinib (bodyweight ≥ 60 kg, 12 mg; < 60 kg, 8 mg) orally daily and pembrolizumab 200 mg intravenously on day 1 of a 21-day cycle. The study included a dose-limiting toxicity (DLT) phase and an expansion phase (first-line patients). Primary objectives were safety/tolerability (DLT phase), and objective response rate (ORR) and duration of response (DOR) by modified RECIST (mRECIST) and RECIST version 1.1 (v1.1) per independent imaging review (IIR; expansion phase).

Results

A total of 104 patients were enrolled. No DLTs were reported (n = 6) in the DLT phase; 100 patients (expansion phase; included n = 2 from DLT phase) had received no prior systemic therapy and had Barcelona Clinic Liver Cancer stage B (n = 29) or C disease (n = 71). At data cutoff, 37% of patients remained on treatment. Median duration of follow-up was 10.6 months (95% CI, 9.2 to 11.5 months). Confirmed ORRs by IIR were 46.0% (95% CI, 36.0% to 56.3%) per mRECIST and 36.0% (95% CI, 26.6% to 46.2%) per RECIST v1.1. Median DORs by IIR were 8.6 months (95% CI, 6.9 months to not estimable [NE]) per mRECIST and 12.6 months (95% CI, 6.9 months to NE) per RECIST v1.1. Median progression-free survival by IIR was 9.3 months per mRECIST and 8.6 months per RECIST v1.1. Median overall survival was 22 months. Grade ≥ 3 treatment-related adverse events occurred in 67% (grade 5, 3%) of patients. No new safety signals were identified.

Conclusion

Lenvatinib plus pembrolizumab has promising antitumor activity in uHCC. Toxicities were manageable, with no unexpected safety signals.

Project description:BackgroundCombining an antiangiogenic agent with an anti-PD-1 agent is a promising strategy for unresectable hepatocellular carcinoma (HCC).AimsTo explore the effectiveness and tolerability of lenvatinib plus camrelizumab vs. lenvatinib monotherapy as a first-line treatment for unresectable HCC.MethodsThis multicenter, retrospective cohort study included patients with unresectable HCC treated with oral lenvatinib 8 mg daily and intravenous camrelizumab 200 mg every 3 weeks (L+C group) or lenvatinib 12 mg or 8 mg daily (L group) in four Chinese centers between September 2018 and February 2020. Tumor response was evaluated according to RECIST 1.1 and mRECIST. The outcomes included objective response rate (ORR), overall survival (OS), 1-year OS rate, progression-free survival (PFS), and safety.ResultsBy March 31, 2021, 92 patients were finally included, with 48 and 44 in the L+C and L groups, respectively. ORR was significantly higher in the L+C group than in the L group (RECIST 1.1: 37.5% vs. 13.6%, P=0.009; mRECIST: 41.7% vs. 20.5%, P=0.029). Median OS and 95% confidence interval (CI) was 13.9 (13.3-18.3) months in the L group and not reached in the L+C group (P=0.015). The 1-year survival rate was 79.2% and 56.8% in the L+C and L groups, respectively. Median PFS was 10.3 (6.6-14.0) months and 7.5 (5.7-9.3) months in the L+C and L groups, respectively (P=0.0098). Combined therapy vs. monotherapy was independently associated with a prolonged OS (hazard ratio=0.380, 95% CI=: 0.196-0.739, P=0.004) and a prolonged PFS (hazard ratio=0.454, 95%CI=0.282-0.731, P=0.001). The safety profile was comparable between the two groups. The most common adverse event in the L+C and L groups was loss of appetite (41.7% vs. 40.9%, P=0.941). Three patients in the L+C group and two in the L group terminated treatment owing to adverse events.ConclusionFirst-line lenvatinib plus camrelizumab showed better effectiveness than lenvatinib alone in patients with unresectable HCC.

Project description:BackgroundLenvatinib, a multi-targeted tyrosine kinase inhibitor (TKI), has proven efficacy as the first-line treatment for patients with advanced hepatocellular carcinoma (HCC). However, there is no standard effective second-line treatment option following progression on lenvatinib therapy. Because of the comprehensive coverage of therapeutic targets of lenvatinib, the remission rate of other TKI treatments in HCC patients resistant to lenvatinib is quite low.MethodsIn this study, the effectiveness and safety of anti-programmed cell death protein-1 (PD-1) antibodies plus lenvatinib were assessed in 46 patients between April 2018 and April 2020 at the Zhongshan Hospital, Fudan University, by retrospectively reviewing their clinical data. Patients with unresectable HCC who progressed on lenvatinib were given standard doses of lenvatinib and anti-PD-1 antibodies. They were followed-up every 6-8 weeks with medical imaging and laboratory tests and treatment-related adverse reactions were investigated.ResultsThe objective response and the disease control rates were 23.9% (11/46) and 71.7% (33/46), respectively by Response Evaluation Criteria in Solid Tumours 1.1 (RECIST). After a median follow-up period of 15.6 [interquartile range (IQR), 11.2-22.0] months, the median progression-free survival (PFS) and overall survival (OS) were 6.9 months [95% confidence interval (CI): 2.1-11.8] and 14.5 months (95% CI: 6.8-22.3), respectively. The most common treatment-related adverse events were anorexia (43.5%), hypothyroidism (43.5%), hypertension (36.9%), fatigue (34.8%), and diarrhea (26.1%). Grade 3/4 events occurred in 16 patients (34.8%). Emotional functioning and overall quality of life were improved significantly following the initiation of anti-PD-1 antibodies plus lenvatinib therapy (fatigue, 4.9±7.5 vs. 11.1±12.7, P=0.03; diarrhea, 12.3±20.9 vs. 18.5±16.8, P=0.01; pain, 5.5±10.3 vs. 11.1±13.9, P=0.01).ConclusionsThe combination of anti-PD-1 antibodies and lenvatinib may benefit patients with unresectable HCC who progressed on lenvatinib. This study provides a real-world data and treatment choice for patients progressed with lenvatinib.
