Dose Escalation of RMC-4630 Monotherapy in Relapsed/Refractory Solid Tumors

This is an open-label, multicenter, Phase 1 study of oral RMC-4630 monotherapy in participants with advanced relapsed or refractory solid tumors. The study will include 2 components: 1) a Dose-Escalation Component for participants with relapsed or refractory solid tumors and 2) a Dose-Expansion Component for participants with relapsed or refractory solid tumors harboring certain specific mutations/rearrangements that result in hyperactivation of the RAS-MAPK pathway. Participants will be treated until disease progression per RECIST v1.1, unacceptable toxicity, or other criteria for withdrawal are met, whichever occurs first.
