This open-label, phase 1b/2 dose-escalation and dose-expansion study is designed to evaluate the safety and maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of RMC-4630 in combination with cobimetinib in participants with relapsed/refractory solid tumors; and of RMC-4630 in combination with osimertinib in adult participants with EGFR mutation-positive locally advanced or metastatic NSCLC.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) proﬁles of RMC-4630 and cobimetinib in adult participants with relapsed/refractory solid tumors with specific genomic aberrations and to identify the recommended Phase 2 dose (RP2D); and to evaluate the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) proﬁles of RMC-4630 and osimertinib in adult participants with EGFR mutation-positive locally advanced or metastatic NSCLC.
