Palovarotene

FOP is caused by a mutation in the ACVR1 gene that results in excessive bone morphogenetic protein (BMP) signaling, which regulates cartilage and bone development. The FOP mutation increases BMP signaling, resulting in the formation of heterotopic bone. By reducing BMP signaling, palovarotene may reduce the volume of heterotopic bone formed in FOP patients. Palovarotene has received Orphan Drug status for FOP from the U.S. Food and Drug Administration (FDA), and orphan status for the treatment of FOP in the EU. In addition, palovarotene has been granted Fast Track and Breakthrough Therapy designations for FOP from the FDA.

About the Clinical Trial

The palovarotene Phase 3 trial is a global, multi-center, open-label (no placebo – see below study design) single-treatment arm trial in which all subjects receive palovarotene dosing. The study was designed to enroll approximately 80 adults and children age 4 years and older with the classic FOP mutation (R206H mutation). Key objectives are to evaluate the safety of palovarotene, and whether a daily dosing regimen of the drug, with higher doses during times of flare-ups, will reduce the formation of new HO as measured by whole body CT scan.
