Overview
The purpose of this platform study is to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of novel RAS(ON) inhibitors combined with Standard(s) of Care (SOC) or with each other.
The first two subprotocols include the following:
Subprotocol A: RMC-6291 + SOC Subprotocol B: RMC-6236 + SOC
Description
The platform study design allows combinations of RAS(ON) inhibitors with other anticancer agents to be evaluated in patients with RAS-mutated solid tumors with a focus on NSCLC.
This is an open-label platform Phase 1b/2 study to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of novel RAS(ON) inhibitors combined with Standard of Care (SOC), and to define the Recommended Phase 2 Dose and Schedule (RP2DS). Enrollment of patients with KRAS or RAS mutations will be specified in each subprotocol.
Subprotocol A is an open-label, multicenter, Phase 1b/2 study of RMC-6291 in combination with pembrolizumab, with or without chemotherapy, in patients with KRAS G12C-mutated advanced solid tumors.
Subprotocol B is an open-label, multicenter, Phase1b/2 study of RMC-6236 in combination with pembrolizumab, with or without chemotherapy, in patients with RAS-mutated non-small cell lung cancer (NSCLC)
Each subprotocol consists of two parts: Part 1 - Dose Exploration and Part 2 - Dose Expansion.
