NEW YORK–(BUSINESS WIRE)–$RCKT #GeneTherapy—Rocket Pharmaceuticals, Inc. (NASDAQ: RCKT) (“Rocket”), a clinical-stage company advancing an integrated and sustainable pipeline of genetic therapies for rare childhood disorders, today reports financial results for the quarter that ended September 30, 2020, along with an update on the Company’s key pipeline developments, business operations and upcoming milestones.

“We are incredibly pleased with the steady progress we made across all five of our clinical programs this quarter. The data from our RP-L201 trial for LAD-I demonstrated the potential for a very robust and attractive profile for our ‘Process B’ lentiviral gene therapy pipeline. We also treated our first higher dose patient in our Phase 1 study of RP-A501 for the treatment of Danon Disease, and presented compelling preclinical data in IMO,” said Gaurav Shah, M.D., President and Chief Executive Officer of Rocket. “In addition, I am proud that against the backdrop of a global pandemic, while there have been some delays in patient follow up and data collection, we continued to enroll and treat patients in our LVV and AAV gene therapy programs as well as expand our clinical trials internationally. Finally, we made strong progress in the build-out of Rocket’s AAV R&D and manufacturing facility, with the ability to produce GMP product anticipated in 2021.”

Dr. Shah continued, “We are looking forward to sharing additional updates as we enter the fourth quarter. These data announcements include an update on the Phase 1 and 2 trials for FA ‘Process B’, and for the first time, Phase 1 clinical data from our two largest indications: RP-L301 for PKD and RP-A501 for Danon Disease. We believe we are advancing closer to our goal of taking drug products from the discovery phase to BLA submission and launch so we may help improve the lives of patients facing these rare and devastating childhood diseases.”

Key Pipeline Developments and Operational Updates

• Positive clinical update for the Company’s Leukocyte Adhesion Deficiency Program (LAD-I) presented at the European Society for Immunodeficiencies (ESID) 2020 Meeting along with preclinical data from the Company’s Infantile Malignant Osteopetrosis (IMO) program.
  • An oral presentation provided positive longer-term follow-up data from the Phase 1/2 clinical trial of RP-L201 for LAD-I. The data presented in the oral presentation are from two pediatric patients with severe LAD-I, as defined by CD18 expression of less than 2%. Both patients were treated with RP-L201, Rocket’s ex-vivo lentiviral gene therapy candidate. Patient L201-003-1001 was 9 years of age at treatment and has been followed for 12 months and Patient L201-003-1004 was 3 years of age at treatment and has been followed for 4 months. Treatments were well tolerated, and no safety issues were reported with infusion or post-treatment. Both subjects achieved hematopoietic reconstitution in less than 4 weeks. Patient L201-003-1001 demonstrated durable CD18 expression of 40%, peripheral blood VCN levels of 1.3, visible signs of improvement in existing skin lesions and no new infections reported 12 months post-treatment. Patient L201-003-1004 demonstrated CD18 expression of 28% and early peripheral blood VCN trending similarly to the first patient, reported 4 months post-treatment.
  • An e-poster highlighted preclinical trial data on RP-L401 for IMO. Preclinical data on IMO indicate that a modest level of engraftment corrects the disease phenotype in vivo, with increased long-term survival, tooth eruption, weight gain and normalized bone resorption. Results support acceleration into clinical development for RP-L401.
• First patient treated in the higher dose cohort of the Phase 1 dose-escalation clinical trial of RP-A501 for the treatment of Danon Disease. The first patient was treated at the higher dose level of 1.1×10¹⁴ genome copies/kilogram after clearance from the U.S. Food and Drug Administration (FDA) and the Independent Data Safety Monitoring Committee (IDSMC) to move to the higher dose cohort of the study. Preliminary Phase 1 data are anticipated in December assuming no further delays in patient data collection due to COVID-19.
• Opened the Research & Development (R&D) and Chemistry, Manufacturing and Controls (CMC) facility in Cranbury, New Jersey. Approximately half of the newly constructed 103,720 square foot facility will be dedicated to adeno-associated virus (AAV) Current Good Manufacturing Practice (cGMP) manufacturing. As previously guided, the first cGMP clinical product release is expected in 2021.
• Received additional regulatory designations for IMO and Danon Disease programs from U.S. Food and Drug Administration. RP-L401 gene therapy for IMO received Fast Track Designation and RP-A501 for Danon Disease received Rare Pediatric Disease Designation. The FDA’s Fast Track program facilitates the development of products intended to treat serious conditions that have the potential to address unmet medical needs. The designation enables greater access to the FDA for the purpose of expediting the product’s development, review and potential approval. The FDA grants Rare Pediatric Disease Designation for serious and life-threatening diseases that primarily affect children ages 18 years or younger and fewer than 200,000 people in the U.S.
• Expanded clinical sites for Fanconi Anemia (FA), Danon, LAD-I and IMO trials, adding to global centers of excellence. The newly added centers, which include some of the leading gene therapy research programs in the world, include: Great Ormond Street Hospital (GOSH), Children’s Hospital of Philadelphia (CHOP), the University of Minnesota and the University of California, Los Angeles (UCLA). We anticipate these additional sites will expand patient access to Rocket’s clinical trials worldwide.
• Hosted third Pyruvate Kinase Deficiency (PKD) Day in October. Continuing its commitment to the patient communities it serves, Rocket facilitated the first virtual edition of PKD Day. The event, intended for patients with PKD and their families, gave attendees an introduction to PKD, gene therapy and Rocket’s clinical program and provided time for a Q&A session with experts in the field and Rocket team members.

Anticipated Milestones

• FA (RP-L102)
  • Preliminary “Process B” data (12/20)
  • Updated “Process B” data (1H21)
• Danon Disease (RP-A501)
  • Preliminary Phase 1 data (12/20)
  • Updated Phase 1 data (2H21)
• LAD-I (RP-L201)

Third Quarter Financial Results

• Cash position. Cash, cash equivalents and investments as of September 30, 2020 were $228.7 million.
• Debt. Our balance sheet includes $52.0 million of fully convertible notes.
• R&D expenses. Research and development expenses were $21.7 million for the three months ended September 30, 2020, compared to $14.8 million for the three months ended September 30, 2019, primarily due to increases in manufacturing and development costs, clinical trial expenses, license fees, and compensation and benefit expenses due to increased R&D headcount.
• G&A expenses. General and administrative expenses were $5.7 million for the three months ended September 30, 2020, compared to $4.3 million for the three months ended September 30, 2019, primarily due to increases in non-cash stock compensation expense and an increase in compensation and benefit expenses due to increased G&A headcount.
• Net loss. Net loss was $29.0 million or $0.53 per share (basic and diluted) for the three months ended September 30, 2020, compared to $19.3 million or $0.38 per share (basic and diluted) for the three months ended September 30, 2019.
• Shares outstanding. 55,204,127 shares of common stock were outstanding as of September 30, 2020.

Financial Guidance

• Cash position. As of September 30, 2020, we had cash, cash equivalents and investments of $228.7 million. Rocket expects such resources will be sufficient to fund its operations into the second quarter of 2022.
