Frequently asked questions about Olomorasib

What is Olomorasib used for?

Olomorasib is an investigational small molecule being studied for use in non-small cell lung cancer, specifically in participants with resected or unresectable KRAS G12C-mutant disease. It is also being studied in healthy participants and those with hepatic insufficiency to evaluate its safety and pharmacokinetics.

Who makes Olomorasib?

Olomorasib is being developed by Eli Lilly and Company, traded on the New York Stock Exchange under the ticker LLY. The company is conducting clinical trials of this investigational drug across multiple countries.

What phase is Olomorasib in?

Olomorasib is in Phase 3 clinical development for non-small cell lung cancer. It has received Breakthrough Therapy designation from the FDA. The drug remains investigational and has not been approved for any use.

What clinical trials is Olomorasib in?

Olomorasib is being studied in a Phase 3 trial (NCT06890598) combining it with standard of care in KRAS G12C-mutant non-small cell lung cancer, currently recruiting 700 participants. Completed Phase 1 trials include NCT06719128 in hepatic impairment and healthy participants, NCT07044271 in healthy participants, and NCT07124013 in healthy Japanese participants.

Is Olomorasib the same as LY3537982?

Yes, Olomorasib is also known as LY3537982. Clinical trial records use both names interchangeably, with LY3537982 appearing in the official study titles for the drug's trials.

What does Olomorasib target?

Olomorasib targets the KRAS G12C mutation, a specific genetic alteration found in certain cancers. The drug is being evaluated in non-small cell lung cancer patients whose tumors harbor this KRAS G12C mutation.
