About this update from Prime Medicine, Inc.
CAMBRIDGE, Mass., May 07, 2026 (GLOBE NEWSWIRE) -- Prime Medicine, Inc. (Nasdaq: PRME), a biotechnology company committed to delivering a new class of differentiated one-time curative genetic therapies, today reported financial results for the quarter ended March 31, 2026 and provided a business update. “Prime Medicine continues to execute with clear momentum and a focused strategy designed to deliver on the transformative potential of Prime Editing,” said Allan Reine, M.D., Chief Executive Officer of Prime Medicine. “We remain on track to file regulatory applications for PM577 in Wilson Disease in the first half of this year, and for PM647 in AATD mid-year, bringing two of our most advanced programs to the brink of clinical entry, with initial data from both expected in 2027. In parallel, we continue to progress toward a potential BLA filing for PM359, which, if successful, would bring a one-time, potentially curative therapy to people living with CGD, who today face a lifetime of debilitating infections and limited treatment options. With a strengthened leadership team and a continued commitment to disciplined capital allocation, we believe Prime Medicine is well positioned to execute across our pipeline and unlock the broad promise of Prime Editing for patients.” Prime Medicine’s Pipeline: Prime Medicine is currently advancing in vivo programs to cure two of the largest genetic liver diseases, Wilson Disease (WD) and Alpha-1 Antitrypsin Deficiency (AATD). Prime Medicine expects to file an Investigational New Drug application (IND) and/or Clinical Trial Application (CTA) for PM577 in WD in the first half of 2026 and for PM647 in AATD in mid-2026; initial clinical data from both programs are expected in 2027. Prime Medicine is also advancing an in vivo Cystic Fibrosis (CF) program with support from the Cystic Fibrosis Foundation, and efforts to develop Prime Edited CAR-T products for hematology, immunology and oncology in partnership with Bristol Myers Squibb. Additionally, following positive proof-of-concept data from the first two patients treated in its Phase 1/2 study of PM359 for the treatment of Chronic Granulomatous Disease (CGD), Prime Medicine continues to engage in regulatory dialogue with the U.S. Food and Drug Administration (FDA) toward a potential Biologics License Application (BLA) filing for PM359.
