Detaljeret beskrivelse
This is a multicenter, open-label extension (OLE) study designed to provide continued access to the investigational product ATH434 for eligible participants with Multiple System Atrophy (MSA) who have successfully completed the prior Phase 2 clinical trial (ATH434-201) in France. Up to 5 participants will be enrolled. No new participants will be recruited or enrolled in this study.
The primary objective is to monitor long-term safety, tolerability, and clinical response. Eligible participants will receive ATH434 at a dose of 75 mg twice daily (BID) to be taken with food.
The study is divided into two operational phases:
Initial Treatment Phase: Participants will receive treatment for a planned duration of 12 months.
Extension Phase: Participants may continue treatment beyond the initial 12 months based on the investigator's clinical judgment of ongoing benefit, safety, and tolerability. Continued eligibility will be re-evaluated and documented every 3 months.
Participants will undergo a combination of in-clinic and remote visits to perform safety monitoring, clinical evaluations, and investigational product accountability.
