Intervention Model Description
In the double-blind period, participants will be randomized at a 2:1 ratio to either receive bemdaneprocel or undergo sham surgery. Participants will receive immunosuppression or placebo equivalents for approximately 12 months. Approximately 18 months after the last participant is enrolled and based on the results of the primary analysis and review by the independent data monitoring committee (DMC), eligible participants who underwent sham surgery and remain actively enrolled in the study will have the opportunity to receive bemdaneprocel in the open-label period.

Detailed Description

The BRT-DA01-301 study is a Phase 3, multicenter, randomized, sham surgery-controlled, double-blind study involving approximately 102 participants with Parkinson's Disease (PD). Participants will be randomized in a 2:1 ratio to either receive bemdaneprocel or undergo sham surgery. The study includes an immunosuppression regimen and placebo equivalents to maintain blinding. The primary objective is to evaluate the efficacy of bemdaneprocel on motor symptoms in participants with PD. The secondary objective is to evaluate the effects of bemdaneprocel on Motor function, Quality of life, Non-motor symptoms of PD, Disease severity, and Use of PD medications or therapies compared with participants who undergo sham surgery. Participants will be followed for at least 18 months in the double-blind period and up to five years if they receive bemdaneprocel.
