Rinvatercept Enters Phase 2 Trial Design for ALS
Keros Therapeutics announced an agreement with Massachusetts General Hospital to design a Phase 2 clinical trial for rinvatercept in patients with amyotrophic lateral sclerosis (ALS) within the HEALEY ALS MyMatch program. This expands the potential indications for its lead product candidate.

Positive Phase 1 Rinvatercept Data Presented
The company presented additional positive data from its Phase 1 clinical trial of rinvatercept in healthy volunteers at the 2026 Muscular Dystrophy Association Clinical & Scientific Conference, reinforcing its mechanism of action and potential in neuromuscular diseases.
Analysis · KROS · Life Sciences
Keros Therapeutics is significantly advancing its lead product candidate, rinvatercept, by expanding its clinical development into Amyotrophic Lateral Sclerosis (ALS), a severe neurodegenerative disease with high unmet medical need. The collaboration with Massachusetts General Hospital and the HEALEY ALS MyMatch program provides a credible and structured pathway for designing a Phase 2 trial. Concurrently, the presentation of additional positive Phase 1 data further de-risks the program by reinforcing rinvatercept's mechanism of action, safety profile, and observed effects on muscle mass and bone mineral density. These developments build on the company's recent positive financial results and pipeline updates, strengthening the investment thesis around rinvatercept's potential in neuromuscular diseases, including Duchenne muscular dystrophy (DMD) and now ALS.
