Phase Ib/II Study of INC280 + PDR001 or PDR001 Single Agent in Advanced HCC

Novartis Pharmaceuticals89 enrolled

Overview

The purpose of this study of capmatinib (INC280) and spartalizumab (PDR001) was to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and antitumor activity of spartalizumab administered intravenously (i.v.) as a single agent or in combination with capmatinib administered orally in adult patients with advanced hepatocellular carcinoma (HCC).

This was a Phase Ib/II, open label, multicenter study starting with a Phase Ib dose escalation part followed by a randomized Phase II part in patients with advanced hepatocellular carcinoma. Capmatinib was administered orally twice daily (BID) and spartalizumab was administered i.v. every 3 weeks (Q3W) until the occurrence of unacceptable toxicity, progressive disease as per irRC and/or treatment was discontinued at the discretion of the Investigator or the participant. A complete cycle of treatment was defined as 21 days. During the Phase Ib dose escalation part of the study, participants were treated with capmatinib in combination with a fixed dose of spartalizumab until the maximum tolerated dose (MTD) was reached or the recommended phase 2 dose (RP2D) was established. The capmatinib dose was increased and the spartalizumab dose remained constant. Once the MTD and/or RP2D were declared for capmatinib in combination with spartalizumab, additional participants were enrolled in the Phase II part in order to assess the anti-tumor activity of capmatinib in combination with spartalizumab and spartalizumab single agent. Participants were randomly assigned, in a 1:1 ratio, to treatment with either capmatinib in combination with spartalizumab or spartalizumab single agent.
