Regeneron Pharmaceuticals Inc. (NASDAQ:REGN) on Thursday shared clinical trial results for two investigational therapies targeting recurrent ovarian cancer and muscle loss prevention during weight management.

LGSOC represents up to 10% of serous ovarian cancers and currently lacks effective treatment options for recurrent cases. Among patients receiving 800 mg monotherapy doses, the drug achieved a 73% objective response rate, an 11-month median progression-free survival, and a 9-month median duration of response. Consequently, the company is enrolling a potentially registrational trial and preparing to consult with the U.S. Food and Drug Administration regarding a confirmatory Phase 3 study. Safety assessments across 19 patients showed treatment-emergent adverse events in all participants, though cytokine release syndrome cases were limited to Grade 1 or 2. Muscle Preservation in Weight Loss During a Scientific Symposium at the European Association for the Study of Diabetes Annual Meeting, the company highlighted Phase 2 COURAGE trial results for trevogrumab. The anti-myostatin therapy was paired with semaglutide to prevent lean mass loss in adults living with obesity. Lower trevogrumab doses preserved up to 50.7% of lean mass relative to semaglutide monotherapy and retained nearly 70% of thigh muscle volume.

Additionally, partner Hansoh shared Phase 3 results in Chinese patients for olatorepatide, a novel GLP-1/GIP receptor agonist licensed exclusively to the drugmaker outside Greater China.
