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.
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).
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.
Tepotinib improved TTP versus sorafenib and was generally well tolerated in SACT-naive Asian patients with aHCC with MET overexpression.

这项开放标签、1b/2 期研究评估了高度选择性 MET 抑制剂特泊替尼在未接受系统抗癌治疗（SACT）的亚洲晚期肝细胞癌（aHCC）伴 MET 过表达患者中的疗效。
在 2b 期，特泊替尼在亚洲成年人中每日口服一次（300、500 或 1000mg）用于治疗 aHCC。主要终点为剂量限制毒性（DLT）和不良事件（AE）。2 期将 SACT 初治的亚洲成年人 aHCC 伴 MET 过表达患者随机分配至特泊替尼（推荐的 2 期剂量[RP2D]）或索拉非尼 400mg 每日两次。主要终点为无进展生存时间（TTP）。
在 1b 期（n=27）中，未发生 DLT；RP2D 为 500mg。在 2 期（n=90，每组 45 例）中，主要终点达到：与索拉非尼相比，特泊替尼的 TTP 显著延长（中位 TTP 为 2.9 个月与 1.4 个月，HR=0.42，90%置信区间：0.26-0.70，P=0.0043）。无进展生存和客观缓解也有利于特泊替尼。特泊替尼治疗相关的≥3 级 AE 发生率为 28.9%，而索拉非尼为 45.5%。
特泊替尼与索拉非尼相比，可改善 TTP，且在未接受 SACT 的亚洲 aHCC 伴 MET 过表达患者中总体耐受良好。
