Brief summary
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of RMC-5127 as a monotherapy and in combination with either daraxonrasib or cetuximab in adults with KRAS G12V-mutant solid tumors.
Detailed description
This is an open-label, multicenter, Phase 1/1b study of RMC-5127 in adults with advanced KRAS G12V-mutant solid tumors to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary clinical activity. The study consists of three arms: RMC-5127 monotherapy arm, RMC-5127 plus daraxonrasib combination arm, and RMC-5127 plus cetuximab combination arm. All arms consist of two parts: Part 1- dose exploration and Part 2- dose expansion. Both parts of the monotherapy arm may include Food Effect Cohorts.
