— Data demonstrated RP-A501 was well tolerated and showed increasing and durable benefit —
— Low-dose pediatric patient cohort expected to commence in Q3; full update anticipated Q4 —
CRANBURY, N.J.--(BUSINESS WIRE)-- Rocket Pharmaceuticals, Inc. (NASDAQ: RCKT), a clinical-stage company advancing an integrated and sustainable pipeline of genetic therapies for rare childhood disorders, today announces an oral presentation of previously disclosed data from the ongoing Phase 1 trial of RP-A501 for the treatment of Danon Disease was given at the Heart Failure Society of America (HFSA) Annual Scientific Meeting 2021. The presentation overviewed data from the low-dose (6.7e13 vg/kg) cohort which demonstrated the investigational gene therapy RP-A501 was well tolerated and showed progressive and durable clinical benefit.
"Patients with Danon Disease desperately need a treatment option that provides meaningful therapeutic benefit with a manageable safety profile, and we are excited to be a part of the HFSA Annual Meeting and to share this important work," said Jonathan Schwartz, M.D., chief medical officer of Rocket Pharma. "We continue to be encouraged by the safety and durable clinical benefit RP-A501 has demonstrated in the low dose, with one patient now followed to 24 months. Additionally, we are working expeditiously to commence treatment in the low-dose (6.7e13 vg/kg) pediatric patient cohort in the third quarter and expect to provide a comprehensive clinical update from the Phase 1 trial in the fourth quarter."
Data from the Low-Dose Adult Cohort (n=3) of the Phase 1 Trial of RP-A501 in Danon Disease
RP-A501 is an investigational gene therapy product being developed for Danon Disease and the first potential gene therapy for monogenic heart failure. It consists of a recombinant adeno-associated serotype 9 (AAV9) capsid containing a functional version of the human LAMP2B transgene (AAV9.LAMP2B). RP-A501 is currently being evaluated in an ongoing Phase 1 clinical trial, from which preliminary data of the low-dose cohort showed it was generally well tolerated and provided evidence of improved cardiac function in patients.
About Danon Disease
Danon Disease is a rare X-linked inherited disorder caused by mutations in the gene encoding lysosome-associated membrane protein 2 (LAMP-2), an important mediator of autophagy. This results in accumulation of autophagosomes and glycogen, particularly in cardiac muscle and other tissues, which ultimately leads to heart failure, and for male patients, frequent death during adolescence or early adulthood. It is estimated to have a prevalence of 15,000 to 30,000 patients in the U.S. and Europe. The only available treatment option for Danon Disease is 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. (NASDAQ: RCKT) ("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.
