CRANBURY, N.J. --(BUSINESS WIRE)--Nov. 6, 2025-- Rocket Pharmaceuticals, Inc. (NASDAQ: RCKT), a fully integrated, late-stage biotechnology company advancing a sustainable pipeline of genetic therapies for rare disorders with high unmet need, today reported financial and recent operational results for the third quarter ending September 30, 2025 .
“During the third quarter, we maintained disciplined execution and sharpened our strategic focus on Rocket’s AAV cardiovascular gene therapy portfolio,” said Gaurav Shah , M.D., Chief Executive Officer of Rocket Pharmaceuticals . “In under three months, we aligned with the FDA to resume the Phase 2 pivotal study of RP-A501 for Danon disease, an important milestone that underscores the FDA’s collaborative approach and recognition of the urgent need for innovative therapies in rare cardiovascular disorders. In parallel, we are advancing RP-A601 toward a pivotal Phase 2 study in PKP2-ACM and preparing RP-A701 for first-in-human evaluation in BAG3-DCM. Finally, the upcoming March PDUFA date for KRESLADI™ represents a significant near-term commercial milestone as we work to bring this potentially life-saving therapy to patients with severe LAD-I.”
Recent Pipeline and Operational Updates
Dosing of additional patients for the Phase 2 study of RP-A501 for Danon disease anticipated in the first half of 2026. In August, Rocket disclosed that the U.S. Food and Drug Administration’s (FDA) lifted the clinical hold on the Company’s pivotal Phase 2 trial of RP-A501 for the treatment of Danon disease in under three months. Per agreement with the FDA, three additional patients will be treated at a recalibrated dose of 3.8 × 10¹³ GC/kg with a minimum four-week interval between dosing and a modified immunomodulatory regimen. Following the treatment of these three patients, Rocket will align with the FDA regarding the path forward for completion of the Phase 2 pivotal study. Details of the Phase 2 pivotal study can be found at www.ClinicalTrials.gov under NCT identifier NCT06092034.

Phase 1 trial start-up activities are ongoing for RP-A701 in BAG3-associated dilated cardiomyopathy (BAG3-DCM). The first-in-human Phase 1 clinical trial will be a multi-center, dose-escalation study designed to evaluate the safety, biological activity, and preliminary efficacy of RP-A701 in adults with BAG3-DCM. Details of the Phase 1 study can be found at www.ClinicalTrials.gov under NCT identifier NCT07137338.
