Regeneron says Phase 3 OPTIMA extension shows zero new HO lesions with Pasatru in adult FOP patients through week 84

By Public Technologies
  • Regeneron reported 84-week Phase 3 OPTIMA extension results for Pasatru in adults with fibrodysplasia ossificans progressiva, presented at ASBMR.
  • Extension data showed sustained suppression of new abnormal bone growth, supporting longer-term disease control beyond the initial placebo-controlled period.
  • Clinician-assessed flare-ups stayed lower on treatment versus placebo, reinforcing the drug’s disease-modifying profile in the trial population.
  • Safety remained broadly consistent with earlier findings, with infections rising at higher dosing; no deaths were reported.
  • Regeneron plans to start a Phase 3 OPTIMA 2 study in adolescents and children later this year, expanding the commercial opportunity.
