Fibrodysplasia ossificans progressiva (FOP) is a rare disease characterized by heterotopic ossification (HO) in connective tissues and painful flare-ups. In the phase 2 LUMINA-1 trial, adult patients with FOP were randomized to garetosmab, an activin A-blocking antibody (In the LUMINA-1 trial for fibrodysplasia ossificans progressiva, garetosmab, an activin A monoclonal antibody, did not lead to significant changes in heterotopic ossification lesion activity in pre-existing lesions in period 1. Garetosmab prevented the formation of new lesions in both periods 1 and 2.
