A Study to Evaluate an Investigational Drug (tavapadon) as a Possible Treatment in Early Parkinson’s Disease

Official Title

A PHASE 3, DOUBLE-BLIND, RANDOMIZED, PLACEBO-CONTROLLED, PARALLEL-GROUP, 27-WEEK TRIAL TO EVALUATE THE EFFICACY, SAFETY, AND TOLERABILITY OF TWO FIXED DOSES OF TAVAPADON IN EARLY PARKINSON’S DISEASE (TEMPO-1 TRIAL)

Purpose

The main purpose of this study is to learn how well tavapadon (the study drug) works as a possible treatment for Parkinson’s disease and how safe the study drug is. The target dose range of tavapadon being studied is 5 to 15 mg once daily.

If you choose to participate in this study, you may receive the study drug, or you may receive placebo. A placebo is an inactive material, such as a sugar pill, that looks like the study drug but does not contain any active study drug. Researchers use a placebo to see if the study drug works better or is safer than taking nothing.
You will be in this study for approximately 35 weeks, which includes a screening visit and safety follow up, and you will need to come to the study center at least 11 times over this period.
