A Study to Evaluate the Safety, Tolerability, Pharmacokinetics (PK) and Preliminary Clinical Activity of RO7673396 in Participants With Advanced Solid Tumors Harboring Rat Sarcoma Viral Oncogene Homolog (RAS) Mutation(s)
A Phase I Dose Escalation and Expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Clinical Activity of RO7673396 as a Single Agent and in Combination With Other Anticancer Therapies in Patients With Advanced Solid Tumors Harboring RAS Mutation(s)

INTERVENTIONAL
Conditions
Summary
This study aims to evaluate the safety and tolerability of RO7673396 in participants with advanced solid tumors harboring RAS mutation(s). This study consists of two stages: Stage 1 (Dose Escalation) and Stage 2 (Dose Expansion). Stage 1 will define the recommended dose(s) for expansion (RDEs) of RO7673396. Stage 2 will evaluate preliminary anti-tumor activity of the RDE(s) defined in Stage 1 and of other doses of interest for future development in selected solid tumor indications.
