The FDA has 30 days to review it, and Kohn said if all goes well, enrollment in the trial can begin in January 2023, and his team can treat three to six patients within a year. The extra work required by UCLA to meet the FDA demands took about six months and in September 2022 researchers re-submitted the modified protocol and plans. ![]() ![]() UCLA immediately resumed work on the trials but hit a roadblock in the spring of 2022 when the FDA requested amendments to the newly developed UCLA clinical protocol and manufacturing plans before allowing the clinical trials to move forward. In May 2021, under pressure from parents whose children with ADA-SCID need gene therapy treatment, Orchard transferred the license back to UCLA. Orchard failed to make progress in gaining Food and Drug Administration (FDA) approval for the treatment and for financial reasons decided not to make the investment necessary to continue with its development. The gene therapy clinical trials stalled in 2018, two years after Orchard Therapeutics licensed the treatment from UCLA with the intention of making it commercially available. Donald Kohn, University of California Los Angeles (UCLA) Department of Microbiology, Immunology, and Molecular Genetics distinguished professor and lead investigator on the trials, shared the news at an Immune Deficiency Foundation (IDF) SCID Compass Lunch & Learn in September. Parents of children with adenosine deaminase (ADA) deficient severe combined immunodeficiency (SCID) learned that after several years of delay, clinical trials to treat ADA-SCID using gene therapy will resume in 2023.ĭr. ![]()
