We're sorry, but this trial is no longer enrolling volunteers.
A Phase 2B, Twelve-week Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study, To Determine the Safety, Tolerability and Efficacy of Two Doses of Once Daily P2B001 in Subjects With Early Parkinson's Disease
Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.
