Fibrodysplasia Ossificans Progressiva | Drug: Palovarotene | Phase 3 |
One primary objective is to evaluate the efficacy of palovarotene in decreasing new HO in subjects with FOP as assessed by low-dose, whole body computed tomography (WBCT), excluding head, compared to untreated subjects from Clementia's FOP natural history study (Study PVO-1A-001, NHS). The other primary objective is to evaluate the safety of palovarotene in subjects with FOP.
This is a Phase 3, multicenter, open-label study. Eligible subjects will receive a chronic/flare-up dosing regimen of palovarotene for 24 months as follows:
- Chronic treatment: orally administered 5 mg palovarotene once daily for 24 months.
- Flare-up treatment: orally administered 20 mg palovarotene once daily for 4 weeks (28 days) followed by orally administered 10 mg palovarotene once daily for 8 weeks (56 days). Flare-up treatment may be extended until the Investigator determines that the flare-up has resolved.
Note that all dosing will be weight-adjusted in skeletally immature subjects (those under the age of 18 years with less than 90% skeletal maturity on hand/ wrist x-rays performed at Screening).

Estimated Enrollment : | 80 participants |
Intervention Model: | Single Group Assignment |
Intervention Model Description: | A multicenter, open-label study. Untreated subjects from the FOP NHS will serve as the control arm. |

Experimental: Palovarotene Chronic/Flare-Up Regimen
Subjects will receive 5 mg palovarotene once daily for up to 24 months; and 20 mg palovarotene once daily for 28 days, followed by 10 mg for 56 days for flareups. (Dosing will be adjusted for weight in skeletally immature subjects.)

Drug: Palovarotene
Palovarotene will be taken orally once daily at approximately the same time each day following a meal.

- Number of Body Regions with HO [ Time Frame: Screening, every 6 months up to 2 years ]Change from baseline in the number of body regions with new HO.
- Subjects with Flare-Ups [ Time Frame: Up to 2 years ]The proportion of subjects reporting flare-ups.
- Rate of Flare-Ups [ Time Frame: Up to 2 years ]The rate of flare-ups per subject-month exposure.
- Incidence of Adverse Events [ Time Frame: Up to 2 years ]Monitor adverse events.
- Palovarotene Area Under the Curve (AUC) [ Time Frame: Predose, and 3, 6, 10, and 24 hours postdose ]Determination of AUC at steady-state assessed during treatment with 5, 10, and 20 mg palovarotene.
- Range of Motion [ Time Frame: Screening, every 6 months up to 2 years ]Change from baseline in range of motion as assessed by the Cumulative Analogue Joint Involvement Scale for FOP (CAJIS).
- FOP-Physical Function Questionnaire [ Time Frame: Screening, every 6 months up to 2 years ]Change from baseline in physical function using age-appropriate forms of the FOP-Physical Function Questionnaire (PFQ).
