In this episode of "In the Interim…", Dr. Scott Berry is joined by Dr. Tanya Simuni, Arthur C. Nielsen Jr. Professor of Neurology and Director of the Parkinson’s Disease and Movement Disorders Center at Northwestern University, and Dr. Barbara Wendelberger, Senior Statistical Scientist at Berry Consultants.

Episode 45 of "In the Interim…" highlights the Path to Prevention (P2P) platform trial, the first platform trial designed for a biologically defined prodromal Parkinson’s disease population.

Dr. Scott Berry is joined by Dr. Tanya Simuni (Northwestern) and Dr. Barbara Wendelberger (Berry Consultants) to discuss enrichment via alpha-synuclein pathology (CSF assay) and DAT-SPECT imaging, supporting early-stage targeted enrollment.

The trial features multiple regimens, primary biomarker (DAT-SPECT) and clinical (MDS-UPDRS III) endpoints, and a control structure with shared randomized placebo arms plus PPMI-based non-randomized comparators.

Discover how advanced platform methodology combined with an amazing natural history cohort move prevention trials forward in neurodegenerative disease.
