Experience

Experience developing 9 gene therapy programs from 2014 to 2023. Responsible for the nonclinical development program and IND-enabling GLP toxicity studies for a monogenic eye disease of the retina, the GUCY2D-associated Leber Congenital Amaurosis (LCA1) gene therapy program. The U.S. Food and Drug Administration (FDA) granted the Regenerative Medicine Advanced Therapy (RMAT) designation to this program based on positive 6-month efficacy data from the Phase I/II clinical trial. Responsible for the nonclinical development program and IND-enabling GLP toxicity study for the Angelman Syndrome gene therapy program and subsequent joint regulatory meeting discussing the advancement of the program to a FIH clinical trial. Responsible for the nonclinical aspects of the EU approved AAV2-hAADC (Eladocagene Exuparvovec) gene therapy program. Responsible for additional GLP and non-GLP toxicity studies requested by authorities for AAV2-hAADC, as well as updates to the BLA for these new data plus an overall revision of all nonclinical components of the BLA for submissions/approvals of non-European Union countries.
