How an Ultra-Rare Disease Patient Foundation Advanced a Gene Therapy

RARECast

Multiple sulfatase deficiency is a rare and progressive neurodegenerative disease. The patient advocacy organization United MSD Foundation has been able to advance a gene therapy into preclinical development for the ultra-rare condition through modest investment by pursuing a focused research strategy and leveraging partnerships. In May 2023, The Bespoke Gene Therapy Consortium, the National Institutes of Health-led public-private partnership selected the program for its clinical trial portfolio and will fund a phase 1/2 clinical trial for the therapy. We spoke to United MSD Foundation Executive Director Sarah Cortell Vandryspen, and UT Southwestern Gene Therapy Core Director Steven Gray. about United MSD Foundation’s research strategy, what enabled it to advance a gene therapy as fast as it did, and what other patient organizations can learn from its success.
