Upcoming EL-PFDD Meetings

To promote transparency and communication, FDA is sharing a list of disease areas where a letter of intent (LOI) has been submitted and ongoing plans exist for a future Externally-Led PFDD meeting. While multiple organizations may be working together, the organizations listed below are the primary points of contact for any questions regarding their EL-PFDD meeting.

FDA does not conduct Externally-Led PFDD meetings and a listing on this webpage does not reflect endorsement.
