A Multi-centered, Double-blind, Randomized, Placebo-controlled, Parallel Group Phase 2 Study of TEV-56286 for the Treatment of Patients With Multiple System Atrophy (TOPAS-MSA)

The primary objective of the study is to evaluate the efficacy of TEV-56286 administered orally for the treatment of adult participants with Multiple System Atrophy (MSA).

A secondary objective of the study is to evaluate specific efficacy parameters of TEV-56286.

Another secondary objective is to evaluate the safety and tolerability of TEV-56286.

The planned study period per participant is 56 weeks including a screening period (up to 4 weeks), a 48-week double-blind treatment period, and a follow-up visit (approximately 4 weeks after the end of the double-blind treatment period). The study duration will be approximately 27 months.

Exclusion: has participated in another clinical study involving administration of an IMP within 3 months or 5 half-lives (whichever is longer) of this IMP prior to screening; has a history of, or acknowledges, alcohol or other substance abuse in the 12 months before screening; participant is using or consuming any prohibited concomitant medications within the specified exclusionary windows of this study; Additional criteria apply; please contact the investigator for more information; has 2 or more relatives with history of MSA, suggestive of an alternative diagnosis other than MSA; has a known hypersensitivity to any components of the IMP; is a female participant who is pregnant or breastfeeding, or plans to become pregnant during the study; is of a vulnerable population (eg, people kept in detention or jail).
