Clementia works with urgency and compassion to advance palovarotene, an investigational therapy for people with fibrodysplasia ossificans progressiva (FOP).

For a drug to obtain approval for use in humans, it must first make its way through laboratory testing (also known as preclinical or nonclinical studies) and through rigorous clinical testing phases. Pre-clinical trials involve testing in animal models to determine safety and potential effectiveness, after which the medication may advance to testing in humans, typically consisting of three phases.

The Path to Approval

All drugs must pass through a rigorous development process and regulatory review before being approved for use in humans. The typical path to approval is outlined below.

Phase 1

6 to 18 months

  • Evaluates safety in humans by administering medication to healthy volunteers
  • Collects information about potential side effects

Phase 2

18 to 36 months

  • Evaluates safety and efficacy in people with targeted disease

Phase 3

18 to 36 months

  • Evaluates safety and confirms efficacy in people with targeted disease
  • Involves a larger number of affected individuals than a Phase 2 trial
  • Data package can be submitted to regulatory agencies for review and potential approval

Approval

  • Drug approved to market to affected individuals
