Rocket Pharmaceuticals, Inc. (Nasdaq: RCKT) (Rocket), a leading U.S.-based multi-platform gene therapy company, announces the clearance of the Companys Investigational New Drug (IND) application for RP-L102, the Companys lentiviral vector (LVV)-based gene therapy for the treatment of Fanconi Anemia (FA), by the U.S. Food and Drug Administration (FDA). The clinical trial will evaluate Process B which incorporates higher cell doses, transduction enhancers, and commercial-grade vector manufacturing and cell processing. This process improves upon the first-generation process developed in partnership with the Centro de Investigaciones Energticas, Medioambientales y Tecnol³gicas (CIEMAT) )/Ciber of Rare Diseases/Fundaci³n Jimnez Daz in Madrid, Spain.
Today marks Rockets first IND clearance by the FDA and represents an important step forward for the patients and families suffering from FA. Our team worked expeditiously to file this application ahead of schedule so that we may bring RP-L102 forward as quickly as possible,” said Kinnari Patel, Pharm.D., MBA, Chief Operating Officer and Head of Development of Rocket. The U.S. clinical trial will begin in early 2019. The goal of the trial is to evaluate the safety, tolerability, and efficacy of ˜Process B RP-L102 in patients with FA. No conditioning is required due to the selective advantage that is present in FA. We look forward to engaging with regulatory authorities on a final registration path in the second half of 2019 after initial patients have been treated.
The planned clinical trial of Process B RP-L102 is expected to enroll approximately 12 FA patients at the Center for Definitive and Curative Medicine at Stanford University School of Medicine, Hospital Ni±o Jesºs/CIEMAT, and other leading centers in the U.S. and in the EU.
About RP-L102 (LVV-based gene therapy for Fanconi Anemia)
RP-L102 is Rockets lentiviral vector (LVV)-based gene therapy in development for patients with FA with Rockets collaboration partners at Centro de Investigaciones Energticas, Medioambientales y Tecnol³gicas (CIEMAT) in Spain, CIBER-Rare Diseases and IIS-Fundaci³n Jimnez Daz. The International Fanconi Anemia Gene Therapy Working Group helped the development of new generation of FA gene therapy programs, which began with a HIV-1-derived, self-inactivating lentiviral vector. RP-L102s lentiviral vector carries the FANC-A gene as part of the PGK-FANCA-WPRE expression cassette which includes a phosphoglycerate kinase (PKG) promoter and an optimized woodchuck hepatitis virus posttranscriptional regulatory element (WPRE). The ex vivo administration process begins with the removal and isolation of hematopoietic stem cells using a CD34+ selection process. Autologous genetically modified CD34+ enriched hematopoietic cells (fresh or cryopreserved) are infused back into patients to restore function. RP-L102 is currently being studied in a Phase 1/2 clinical trial in the European Union with an Investigational Medicinal Product Dossier (IMPD) in place with the Spanish Agency for Medicines and Health Products. The U.S. Food and Administration accepted the Companys Investigational New Drug (IND) application for RP-L102 utilizing Process B which incorporates higher cell doses, transduction enhancers, and commercial-grade vector. RP-L102 has been granted Orphan Drug designation for the treatment of Fanconi Anemia type A in the United States and in Europe.

About Fanconi Anemia
Fanconi Anemia (FA) is a rare pediatric disease characterized by bone marrow failure, malformations and cancer predisposition. The primary cause of death among patients with FA is bone marrow failure, which typically occurs during the first decade of life. Allogeneic hematopoietic stem cell transplantation (HSCT), when available, corrects the hematologic component of FA, but requires myeloablative conditioning, which is highly toxic for the patient HSCT is frequently complicated by graft versus host disease and also increases the risk of solid tumors, mainly squamous cell carcinomas. Approximately 60-70% of patients with FA have a FANC-A gene mutation, which encodes for a protein essential for DNA repair. Mutation in the FANC-A gene leads to chromosomal breakage and increased sensitivity to oxidative and environmental stress. Chromosome fragility induced by DNA-alkylating agents such as mitomycin-C (MMC) or diepoxybutane (DEB) is the ˜gold standard test for FA diagnosis. The DEB assay can further differentiate FA patients from somatic mosaic patients. Somatic mosaicism occurs when there is a spontaneous reversion mutation that can lead to a mixed chimerism of corrected and uncorrected bone marrow cells leading to stabilization or correction of an FA patients blood counts in the absence of any administered therapy. Somatic mosaicism provides strong rationale for the development of FA gene therapy and demonstrates the selective advantage of gene-corrected hematopoietic cells in FA1.

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. Rockets 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. Preclinical studies of additional bone marrow-derived disorders are ongoing and target 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 an undisclosed rare pediatric disease. For more information about Rocket, please visit www.rocketpharma.com.
