* Completion of Study PVO-1A-202/Part B.
* Written, signed, and dated informed consent and, for participants who are minors, age-appropriate participant assent (performed according to local regulations).
* Accessible for treatment with palovarotene and follow-up (able and willing to travel to a site for the initial and all follow-up clinic visits).
* Able to undergo low-dose, WBCT scan, excluding head.

Additionally, sexually active females of childbearing potential (FOCBP) participants must already be using two effective methods of birth control 1 month before treatment is to start. Specific risk of the use of retinoids during pregnancy, and the agreement to remain abstinent or use two effective methods of birth control will be clearly defined in the informed consent and the participant or legally authorized representatives.

Summary
Brief summary
Fibrodysplasia Ossificans Progressiva (FOP) is a rare, severely disabling disease characterized by heterotopic ossification (HO), i.e., abnormal bone formation, often associated with painful, recurrent episodes of soft tissue swelling (flare-ups). Lesions begin in early childhood and lead to progressive ankyloses of major joints with resultant loss of movement.

In this study, the ability of different palovarotene dosing regimens to prevent the formation of new HO will be evaluated in adult and pediatric participants with FOP.
