In May 2024, Prime Medicine announced that the U.S. FDA had accepted its IND application for PM359, a gene therapy involving transplantation of autologous CD34+ stem cells modified by prime editing ex vivo.[2] PM359 also received Rare Pediatric Disease and Orphan Drug designations from the FDA. A Phase 1/2 open-label clinical trial of PM359 in patients with chronic granulomatous disease (CGD) caused by mutations in the neutrophil cytosolic factor 1 (NCF1, also known as p47phox) gene began in October 2024, making PM359 the first prime editor to enter the clinic.[3]
