Prime Medicine, Inc. PRME

Prime Medicine Inc. shares rose more than 12% in after-hours trading after the FDA cleared an Investigational New Drug application for PM647, an in vivo gene-editing therapy for Alpha-1 Antitrypsin Deficiency (AATD). The IND clearance allows the liver-directed therapy to advance to US clinical testing in adults carrying the PiZZ genotype, with initial data expected in 2027. PM647 targets the E342K mutation in SERPINA1 to restore functional M-AAT and address both liver and lung manifestations with a single intravenous infusion. The planned Phase 1/2 trial is global, single-arm, and open-label, starting with participants with lung-dominant disease and expanding to those with significant liver disease. PM647 shares the same liver-directed lipid nanoparticle used in PM577a for Wilson disease, marking the company's second regulatory milestone in recent months. Approximately 200,000 PiZZ carriers exist in the US and Europe; no curative treatment exists today. FDA IND clearance for PM647 expands Prime's pipeline and could significantly affect future value if trials prove safety and efficacy.

Prime Medicine announced FDA clearance of IND for PM647, an in vivo Prime Editor for Alpha-1 Antitrypsin Deficiency (AATD), enabling a Phase 1/2 global, single-arm, open-label trial in the US for PiZZ carriers.
