Rocket Pharmaceuticals, Inc. (Nasdaq:RCKT) (“Rocket”), a leading U.S.-based multi-platform gene therapy company, today announces data presentations at the upcoming American Society of Gene and Cell Therapy (ASGCT) 2019 Annual Meeting taking place April 29 – May 2, 2019, in Washington, D.C. Presentations at this year’s meeting include 4 oral presentations and 3 poster presentations related to Rocket’s four leading pipeline programs: lentiviral vector (LVV) based gene therapy programs for Fanconi Anemia (FA), Pyruvate Kinase Deficiency (PKD), and Leukocyte Adhesion Deficiency-I (LAD-I) and adeno-associated viral vector (AAV) based gene therapy program for Danon disease.

“Rocket is pleased to share additional emerging preclinical and clinical data from several gene therapy pipeline programs at ASGCT,” said Gaurav Shah, M.D. Chief Executive Officer and President of Rocket. “This includes updated long-term data from the ongoing Phase 1/2 trial of RP-L102 for FA that utilizes ‘Process A’ without the use of myeloablative conditioning. Results for the four patients who have been followed for at least one year and up to three years show increasing and durable engraftment in peripheral blood and bone marrow, and restoration of bone marrow hematopoietic stem cell function, which we believe suggests patients are approaching an FA mosaic phenotype. These long-term data further support the clinical development of RP-L102 as a potential therapeutic option for FA patients as a means of averting bone marrow failure and avoiding the need for a more toxic bone marrow transplantation.”

Dr. Shah continued, “Data from our preclinical toxicology studies of RP-A501 for Danon disease in mice and non-human primates showed no treatment-related adverse events or safety issues up to the highest dose. There was also robust vector copy number detection in the organs most affected in Danon disease, including high concentrations in heart tissue (~10x higher on average than in skeletal muscle and CNS). We are encouraged by the safety profile of RP-A501 and look forward to initiating our Phase 1 clinical trial of the program in the second quarter of 2019.”

About Rocket Pharmaceuticals, Inc.

Rocket Pharmaceuticals, Inc. (Nasdaq:RCKT) (“Rocket”) is an emerging, clinical-stage biotechnology company focused on developing first-in-class gene therapy treatment options for rare, devastating diseases. Rocket’s multi-platform development approach applies the well-established lentiviral vector (LVV) and adeno-associated viral vector (AAV) gene therapy platforms. Rocket's lead clinical program is a LVV-based gene therapy for the treatment of Fanconi Anemia (FA), a difficult to treat genetic disease that leads to bone marrow failure and potentially cancer. Rocket’s additional pipeline programs for bone marrow-derived disorders are for Pyruvate Kinase Deficiency (PKD), Leukocyte Adhesion Deficiency-I (LAD-I) and Infantile Malignant Osteopetrosis (IMO). Rocket is also developing an AAV-based gene therapy program for a devastating, pediatric heart failure indication, Danon disease.
