Researchers will compare ONO-2808 to a placebo (a look-alike substance that contains no drug) to see if ONO-2808 works to treat MSA-P. Participants will: * Take ONO-2808 or placebo orally for up to 48 weeks * Make visits to the clinic for checkups and tests * Answer questions about their health throughout the trial.","abstract_license":"ClinicalTrials.gov (U.S. National Library of Medicine), data processed 2026-10-29T09:00:05; modifications: selected fields only; whitespace normalized; brief summary truncated to 2,000 characters","license":"ClinicalTrials.gov terms (attribution, processing date, modifications noted)","is_open_access":true,"peer_reviewed":null,"categories":["Multiple System Atrophy, Parkinson Variant"],"details":{"acronym":null,"status":"NOT_YET_RECRUITING","phase":"PHASE3","study_type":"INTERVENTIONAL","enrollment":486,"sponsor":"Ono Pharmaceutical Co., Ltd.","conditions":["Multiple System Atrophy, Parkinson Variant"],"interventions":["DRUG: ONO-2808","OTHER: Placebo"],"start_date":"2027-01-01","start_date_type":"ESTIMATED","primary_completion_date":"2029-10-01","has_results":false,"data_source":"ClinicalTrials.gov","data_processed":"2026-10-29T09:00:05","modifications":"selected fields only; whitespace normalized; brief summary truncated to 2,000 characters"},"provenance":"clinicaltrials","attribution":"Source: ClinicalTrials.gov (U.S. National Library of Medicine), data processed 2026-10-29T09:00:05; modifications: selected fields only; whitespace normalized; brief summary truncated to 2,000 characters.
