Bringing Advanced Therapy Medicinal Products (ATMPs) for Parkinson's Disease to the Clinic: The Investigator's Perspective.

There is much excitement around the use of advanced therapy medicinal products (ATMPs), including cell and gene treatments, in Parkinson's disease (PD). However, taking an ATMP to clinical trials in patients with PD is complex.
