Frequently asked questions about RMC-6291

What is RMC-6291 used for?

RMC-6291 is an investigational small molecule being studied for the treatment of KRAS G12C-mutant solid tumors, including Non-Small Cell Lung Cancer (NSCLC), Colorectal Cancer (CRC), and Pancreatic Ductal Adenocarcinoma. It is currently in Phase 1 clinical development and has not been approved by the FDA.

What does RMC-6291 target?

RMC-6291 targets the KRAS G12C mutation, a specific genetic alteration found in certain cancers. It is designed to inhibit the activity of this mutant protein, which is involved in tumor growth. The drug is being evaluated in patients with advanced solid tumors harboring this mutation.

Who makes RMC-6291?

RMC-6291 is being developed by Revolution Medicines, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol RVMD. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational drug in patients with KRAS G12C-mutated cancers.

What phase is RMC-6291 in?

RMC-6291 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The ongoing trials are designed to assess its safety, tolerability, and preliminary efficacy in patients with advanced KRAS G12C-mutant solid tumors.

What clinical trials is RMC-6291 in?

RMC-6291 is being studied in two Phase 1 clinical trials. The first, NCT05462717, is a dose escalation and expansion study of RMC-6291 monotherapy in advanced KRAS G12C-mutant solid tumors. The second, NCT06162221, evaluates RAS(ON) inhibitors in patients with advanced RAS-mutated NSCLC. Both trials are active.

Is RMC-6291 the same as a RAS(ON) inhibitor?

RMC-6291 is a RAS(ON) inhibitor, a class of drugs that target the active, GTP-bound form of RAS proteins. It specifically targets the KRAS G12C mutation. The drug is being studied alone and in combination with other RAS(ON) inhibitors in clinical trials for advanced solid tumors.
