Overview

The participants in this registry study will have fibrodysplasia ossificans progressiva (FOP).

FOP is an ultra-rare, severely disabling disease characterized by new bone formation in areas of the body where bone is not normally present (heterotopic ossification (HO)).

HO is often preceded by painful, recurrent episodes of soft tissue swelling (flare-ups).

This registry study will take place in countries where the treatment, known as palovarotene, has been approved for use. Participants will either be treated with palovarotene (i.e already be receiving palovarotene as prescribed by their treating physician according to locally approved product information) or untreated with palovarotene.

The main aim of this registry study will be to collect and assess real-world safety data on children and adult participants with FOP treated with palovarotene.

This registry study will also describe the effectiveness of palovarotene in exposed participants, including the effect on everyday activities and physical performance.

In addition, this registry study aims to descriptively compare key safety outcomes (i.e. flare-up episodes, growth outcomes, and bone fractures) between participants exposed and unexposed to palovarotene.

• Adult or child with FOP who have been prescribed palovarotene (prior to and independently of the decision to enroll the patient in this registry study and as per local label) by their treating physician according to the locally approved product information;
• Signed informed consent as per local regulations must be obtained and maintained. Consent/assent from the participant should be obtained as appropriate before any registry study data collection are conducted.
