PCOS Externally-Led Patient Focused Drug Development Meeting (PCOS EL-PFDD Meeting) Presented by PCOS Challenge: The National Polycystic Ovary Syndrome Association. The PCOS EL-PFDD Meeting is the first time PCOS patients’ perspectives will be meaningfully incorporated into drug development. In nearly 90 years since PCOS was first named (Stein-Leventhal Syndrome), there have been no FDA-approved treatments specific to PCOS. This Externally-Led PFDD meeting will provide industry and the FDA invaluable insights regarding patient experiences, perspectives, needs, and priorities to help accelerate the development of new FDA-approved therapies, diagnostics, devices, and other technologies for PCOS.
