Over a 100 patients, caregivers and doctors gathered from across the US, and from as far away as Asia, Europe and Greece to participate in the Externally Led - Patient Focused Drug Development (EL-PFDD) meeting. Additionally, we had participants join us virtually who were unable to travel because of the logistical challenges of traveling with their affected children.

The PFDD initiative was developed for the FDA to systematically obtain the patient perspective on specific diseases and their currently available treatments.

At the PFDD meeting the families highlighted the most significant symptoms of SSADH Deficiency and shared stories to reflect the impact that this disorder has on the patient’s daily life while emphasizing  the lack of treatment options.  The finding are summarized in
the Voice of the Patient report.
