What Taldefgrobep alfa is
Biohaven's anti-myostatin/activin fusion protein being tested as a standalone weight-loss drug, with a Phase 2 obesity readout expected in the second half of 2026.
Taldefgrobep alfa binds myostatin and blocks activin receptor signaling. It missed in a Phase 3 for spinal muscular atrophy, but healthy-volunteer data showed lower fat mass and higher lean mass, and Biohaven fully enrolled a roughly 150-person Phase 2 obesity trial (weekly and monthly autoinjector) in March 2026.
Mechanism: Fusion protein that neutralizes myostatin and inhibits activin receptor type II signaling.
Regulatory history: Investigational; Phase 2
