Rocket Pharmaceuticals, Inc. (RCKT) - Get Report ("Rocket"), a clinical-stage company advancing an integrated and sustainable pipeline of genetic therapies for rare pediatric disorders, today announces it has treated the first patient in the higher dose cohort in its open-label, Phase 1 clinical trial of RP-A501, the Company's adeno-associated viral vector (AAV)-based gene therapy for the treatment of Danon Disease. Treatment of the higher dose cohort comes after successful completion of the low dose cohort and clearance from the U.S. Food and Drug Administration (FDA) and Independent Data Safety Monitoring Committee (IDSMC). The second cohort of the Phase 1 study evaluates RP-A501 at a higher dose level of 1.1×10 14 genome copies/kilogram in male patients 15 years of age and older. The Phase 1 study will assess the safety, tolerability and preliminary efficacy of RP-A501.
"Today marks an important milestone in the development of RP-A501 for Danon Disease, the first investigational gene therapy in development for the treatment of inherited heart failure," said Gaurav Shah, M.D., Chief Executive Officer and President of Rocket. "RP-A501 represents a potentially holistic and transformative approach to Danon Disease, a devastating disease often resulting in end-stage heart failure and early mortality. The only definitive treatment option available for this multisystemic disorder is heart transplantation, which is associated with a 50% mortality rate during the decade following transplant and does not address the full spectrum of the disease course. Our gene therapy approach, utilizing RP-A501, aims to address all manifestations associated with Danon Disease including cardiomyopathy, skeletal myopathy and intellectual disability. We look forward to progressing this trial and enabling a potentially curative treatment option for this devastating disease that affects so many lives."
The non-randomized, open-label Phase 1 trial aims to enroll both pediatric and young adult male patients in escalating dose cohorts. Following the review of safety data from the first cohort, all subsequent cohorts will include 2-4 patients per cohort, adjusted down from 3-6 patients in the original protocol. The study is designed to assess the safety and tolerability of a single intravenous (IV) infusion of RP-A501. Additional outcome measures include cardiomyocyte and skeletal muscle transduction by gene expression, histologic correction via endomyocardial biopsy, and clinical stabilization via cardiac imaging and functional cardiopulmonary testing.
About Danon Disease
Danon disease is caused by mutations in the gene encoding lysosome-associated membrane protein 2 (LAMP-2), an important mediator of autophagy. It is estimated to have a prevalence of 15,000 to 30,000 patients in the U.S. and the European Union. The disease is often fatal in male patients in the second or third decade of life due to rapidly progressive heart failure. Available therapies for Danon disease include cardiac transplantation, which is associated with substantial complications and is not considered curative. There are no specific therapies available for the treatment of Danon disease.
About Rocket Pharmaceuticals, Inc.
Rocket Pharmaceuticals, Inc. (RCKT) - Get Report ("Rocket") is advancing an integrated and sustainable pipeline of genetic therapies that correct the root cause of complex and rare childhood disorders. The company's platform-agnostic approach enables it to design the best therapy for each indication, creating potentially transformative options for patients afflicted with rare genetic diseases. Rocket's clinical programs using lentiviral vector (LVV)-based gene therapy are for the treatment of Fanconi Anemia (FA), a difficult to treat genetic disease that leads to bone marrow failure and potentially cancer, Leukocyte Adhesion Deficiency-I (LAD-I), a severe pediatric genetic disorder that causes recurrent and life-threatening infections which are frequently fatal, Pyruvate Kinase Deficiency (PKD) a rare, monogenic red blood cell disorder resulting in increased red cell destruction and mild to life-threatening anemia and Infantile Malignant Osteopetrosis (IMO), a bone marrow-derived disorder. Rocket's first clinical program using adeno-associated virus (AAV)-based gene therapy is for Danon disease, a devastating, pediatric heart failure condition.
