About

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of escalating doses of RMC-6291 (KRAS G12C(ON) inhibitor) monotherapy in adult subjects with advanced solid tumors and to identify the maximum tolerated dose (MTD), and the recommended Phase 2 dose.

Full description

This is an open-label, multicenter, Phase 1/1b study of RMC-6291 monotherapy in subjects with advanced KRASG12C-mutant solid tumors. The study will include 2 components: a Dose-Escalation and a Dose-Expansion. Subjects will be treated until disease progression per RECIST v1.1, unacceptable toxicity, or other criteria for withdrawal are met, whichever occurs first.

Enrollment: 222 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Subject must be ≥18 years of age.

• ECOG performance status 0 or 1
• Prior treatment with a KRASG12C (OFF) inhibitor allowed for dose escalation
• Adequate organ function

Exclusion criteria

• Primary central nervous system (CNS) tumors
• Active brain metastases
• Known impairment of GI function that would alter the absorption
