EMERYVILLE, Calif., Nov. 09, 2023 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (Nasdaq: FDMT, 4DMT, or the Company) a genetic medicines company with three novel, highly targeted next generation AAV vectors currently in human clinical studies, today reported third quarter 2023 financial results and provided operational highlights.

“The third quarter of 2023 was another period of tremendous progress across our large market product candidate portfolio,” said David Kirn, M.D., Co-founder and Chief Executive Officer of 4DMT. “In our ophthalmology portfolio, the European Medicines Agency has awarded PRIME designation to intravitreal 4D-150 which validates the promising clinical data to date in wet AMD patients. We also enrolled the first patient in the Population Extension cohort to the PRISM clinical trial to include the broader wet AMD patient population with lower anti-VEGF need. In our pulmonology portfolio, we presented positive interim clinical and lung biopsy biomarker data for 4D-710 in the Phase 1/2 AEROW clinical trial for the treatment of cystic fibrosis lung disease, and we selected a dose to move forward into Phase 2. We remain highly focused in executing our corporate objectives and look forward to sharing multiple key clinical and regulatory milestones over the next few months.”

Recent Highlights in Large Market Ophthalmology Portfolio

  • Rapidly advanced intravitreal 4D-150 for wet AMD
    • Completed target enrollment of 50 patients in the randomized Phase 2 Dose Expansion stage of the PRISM clinical trial, nearly two quarters ahead of initial projections
      • Enrolled patients with high anti-VEGF need (annualized mean anti-VEGF injection frequency in preceding 12 months was approximately 10)
      • No reported treatment-emergent Grade ≥1 inflammatory cells or required deviations from protocol-specified topical corticosteroid taper with maximum follow-up through 20 weeks (best available data as of July 3, 2023)
    • Presented positive interim data from Dose Exploration stage with three dose cohorts (3E10, 1E10, and 6E9 vg/eye; n=5 each) at ASRS 2023 Annual Meeting
    • Dosed first patient in Population Extension cohort (n=up to 45) of the Phase 2 PRISM clinical trial including broader wet AMD patient population with lower anti-VEGF need (1-6 anti-VEGF injections in preceding 12 months)
    • Granted PRIME designation by the European Medicines Agency
  • Enrolled first patient in the Dose Confirmation stage (n=18-24) of the Phase 2 SPECTRA clinical trial evaluating intravitreal 4D-150 in patients with DME

Recent Highlights in Pulmonary Portfolio

  • Presented positive interim data from aerosolized 4D-710 Phase 1/2 AEROW clinical trial:
    • Generally well-tolerated across Cohorts 1 and 2 (1E15 and 2E15 vg; n=7) with up to 17 months follow-up
    • Promising, reproducible, CFTR expression significantly above normal across all participants and all lung tissue samples collected (n=34), substantially exceeding target profile
    • Durable clinical activity through 12 months in Cohort 1
      • No pulmonary exacerbations reported beyond 3 months and through up to 17 months of follow-up in all 3 participants
    • Cohort 1 dose level (1E15 vg) selected to continue into Phase 2
    • Dose ranging continues (5E14 – 2E15 vg) with lung biopsy CFTR expression profile demonstrating feasibility of effective treatment at lower doses; first patient dosed in lower dose Cohort 3 (5E14 vg)
  • In August 2023, the Company executed an amendment to the Cystic Fibrosis Foundation Agreement increasing the funding commitment under that agreement by $2.8 million to a total of $6.3 million, which covers anticipated spend for further development of our aerosolized lung epithelium gene delivery vectors. This amendment brings the total historical commitment to over $20 million

Recent Highlights in Cardiology Portfolio

  • Reached an agreement with the FDA on a proposed plan to address the clinical hold on 4D-310 and continue clinical development
    • Initiated single non-human primate (NHP) study evaluating the safety and biodistribution of intravenous (IV) 4D-310 with the rituximab/sirolimus (R/S) immunosuppressive regimen compared to the prior prednisone regimen
    • Amended INGLAXA protocol to minimize risk of atypical hemolytic uremic syndrome associated with IV AAV dosing, including addition of R/S immunosuppressive regimen

Expected Upcoming Milestones

  • 4D-150 for Wet AMD:
    • Phase 2 Dose Expansion (n=50) interim data update early 2024
    • Update on FDA feedback on Phase 3 pivotal trial plans in Q1 2024

Q3 2023 Financial Results

Cash and Cash Equivalents and Marketable Securities: Cash and cash equivalents and marketable securities were approximately $320 million as of September 30, 2023, as compared to $218 million as of December 31, 2022. The net increase in cash was primarily a result of cash inflows from $129 million of net proceeds from our public offering of common stock completed in May, $19 million of net proceeds under our Open Market Sales Agreement, and the $20 million upfront payment in connection with the Astellas License Agreement and was partially offset by cash used in operations. We currently expect cash and cash equivalents to be sufficient to fund operations into the first half of 2026.

R&D Expenses: Research and development expenses were $25.1 million for the quarter ended September 30, 2023 as compared to $18.9 million for the third quarter of 2022. This increase was driven by the progression of our existing clinical trials, primarily 4D-150 in wet AMD and DME, along with increased payroll and stock-based compensation expense due to higher headcount.

G&A Expenses: General and administrative expenses were $9.1 million for the quarter ended September 30, 2023 as compared to $8.1 million for the third quarter of 2022.

Net Loss: Net loss was $10.3 million for the quarter ended September 30, 2023, as compared to net loss of $25.7 million for the third quarter of 2022. The decrease in net loss was primarily a result of the $20 million upfront payment in connection with the Astellas License Agreement.

About 4DMT 

4DMT is a genetic medicines company with three novel, highly targeted next generation AAV vectors currently in human clinical studies targeting multiple large market diseases in ophthalmology and pulmonology, plus other therapeutic areas. 4DMT seeks to unlock the full potential of genetic medicines using its proprietary invention platform, Therapeutic Vector Evolution, which combines the power of the Nobel Prize-winning technology, directed evolution, with approximately one billion synthetic AAV capsid-derived sequences to invent customized and evolved vectors for use in our product candidates. All of our vectors are proprietary to 4DMT and were invented at 4DMT, including the vectors utilized in our clinical-stage and preclinical pipeline product candidates: R100, A101, and C102. The Company is initially focused on five clinical-stage product candidates in three therapeutic areas for both rare and large market diseases: ophthalmology, pulmonology, and cardiology. The 4DMT customized and evolved vectors were invented with the goal of being delivered at relatively low doses through clinically routine, well-tolerated, and minimally invasive routes of administration, transducing diseased cells in target tissues efficiently, having reduced immunogenicity and, where relevant, having resistance to pre-existing antibodies. 4DMT is currently advancing five product candidates in clinical development: 4D-150 for wet AMD and DME, 4D-710 for cystic fibrosis lung disease, 4D-310 for Fabry disease cardiomyopathy, 4D-125 for XLRP, and 4D-110 for choroideremia. The 4D preclinical product candidates in development are: 4D-175 for geographic atrophy and 4D-725 for AATLD. 

4D-150, 4D-710, 4D-310, 4D-125, and 4D-110 are our product candidates in clinical development and have not yet been approved for marketing by the US FDA or any other regulatory authority. No representation is made as to the safety or effectiveness of 4D-150, 4D-710, 4D-310, 4D-125, or 4D-110 for the therapeutic uses for which they are being studied.
