FDA Says Lilly’s Olomorasib is Breakthrough Therapy
FDA has granted breakthrough therapy designation to Lilly’s olomorasib in combination with the anti-PD-1 therapy Keytruda (pembrolizumab) for the first-line treatment of patients with unresectable advanced or metastatic non-small cell lung cancer with a KRAS G12C mutation and PD-L1 expression at or under 50% as determined by FDA-approved tests. A Lilly statement describes olomorasib as an investigational, oral, potent, and highly selective second-generation inhibitor of the KRAS G12C protein. It is said to be a highly potent covalent inhibitor with potential for greater than 90% target occupancy, which may allow for safer combinations with less toxicity.
