## Abstract

The main goal of this clinical trial is to learn if ONO-2808 works to treat adults with the Parkinsonian subtype of Multiple System Atrophy (MSA-P). 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.
