About PRME
Prime Medicine, Inc. is a biotechnology company focused on developing genetic medicines designed to provide durable, and potentially curative, treatment options for patients with diseases driven by defined genetic alterations, acquired cellular dysfunction, or dysregulated gene expression. Its gene editing technology enables targeted modifications to genomic deoxyribonucleic acid (DNA) without introducing double-stranded breaks. The Company pipeline includes wholly owned in vivo programs targeting liver genetic diseases Wilson Disease, Alpha-1 Antitrypsin Deficiency (AATD) as well as early-stage discovery efforts in Cystic Fibrosis (CF). The PM359 is an ex vivo prime editing program designed to correct the GT mutation in the NCF1 gene, the most common cause of Chronic Granulomatous Disease (CGD). This program provides validation of prime editing in human cells. The Wilson Disease is a rare autosomal recessive disorder caused by loss-of-function mutations in ATP7B.

PM359 Receives FDA RMAT Designation, Accelerating Gene Therapy Development
- Clinical Data Support: PM359 has received FDA's Regenerative Medicine Advanced Therapy (RMAT) designation based on Phase 1/2 clinical data, demonstrating its potential to provide significant disease-modifying effects for patients with p47phox-deficient chronic granulomatous disease (CGD).
- Accelerated Approval Pathway: The RMAT designation allows PM359 to benefit from intensive FDA guidance and priority review, combined with Fast Track and Orphan Drug designations, which is expected to expedite the Biologics License Application process, providing the company with faster market access opportunities.
- Urgent Treatment Need: CGD is a rare inherited hematologic disorder that poses severe infection risks and lifelong complications, and the development of PM359 aims to address this unmet medical need, potentially transforming the quality of life for affected patients.
- Technological Platform Advantage: Prime Medicine leverages its proprietary Prime Editing platform to develop a range of gene editing therapies, and the success of PM359 will lay the groundwork for the company's expansion into other disease areas, further enhancing its competitive position in the market.
