A Study to Document and to Further Describe Long-term Safety and Effectiveness of Palovarotene in Participants With Fibrodysplasia Ossificans Progressiva (FOP)
(FOPal)
What this study is about
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).
View original scientific description
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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. If applicable, parents or legally authorized representatives must give signed informed consent.
Exclusion criteria
- Currently participating in a palovarotene clinical trial;
- Currently participating in any interventional clinical trial for FOP;
- Have any contraindication to palovarotene as per the locally approved label (except for pregnant women who have previously received and discontinued palovarotene at any time during the pregnancy and who will be included for safety follow-up).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
