EMERYVILLE, Calif., Nov. 13, 2024 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (Nasdaq: FDMT, 4DMT or the Company), a leading clinical-stage genetic medicines company focused on unlocking the full potential of genetic medicines to treat large market diseases, today reported third quarter 2024 financial results, provided operational highlights and outlined expected upcoming milestones.

“Throughout 2024, 4DMT has generated compelling Phase 1/2 data and executed on Phase 3 preparations for 4D-150 in wet AMD in support of our mission to bring transformative genetic medicines to patients globally. We have built an experienced clinical and commercial team to execute this mission, including with the upcoming initiation of the 4FRONT Phase 3 program expected in Q1 2025,” said David Kirn, M.D., Co-founder and Chief Executive Officer of 4DMT. “In September, we hosted our 4D-150 Wet AMD Development Day, where we presented positive interim data demonstrating the impressive tolerability and clinical activity of 4D-150 and showcased its potential across multiple populations, from the most severe to recently diagnosed patients. The strong data and enthusiastic feedback from our advisors, clinical trial investigators, the retina physician community and the FDA support pivotal development of 4D-150 in the treatment naïve wet AMD population. We believe that these clinical data and this trial design will enable rapid enrollment and achieve positive topline data in the 4FRONT Phase 3 studies.”

Dr. Quezada-Ruiz was most recently Group Medical Director, Ophthalmology at Genentech, where he led clinical development and approval of VABYSMO and SUSVIMO

• Formed Ophthalmology Advisory Board comprised of world-renowned retina specialists and thought leaders to support development strategy and registration across large market ophthalmology indications including wet AMD, DME, diabetic retinopathy, and geographic atrophy: Dr. Arshad Khanani (Chair), Dr. David Boyer, Dr. Frank Holz, Dr. Anat Loewenstein and Dr. Dante Pieramici

• Expanded Scientific Advisory Board with Three New Members:
  • John P. Atkinson, M.D., is Samuel B. Grant Professor of Clinical Medicine at Washington University Division of Biology and Biomedical Sciences. He is a leading expert in rheumatology and innate immunity, specifically the complement system’s role in infectious, autoimmune and inflammatory diseases
  • Napoleone Ferrara, M.D., is currently Distinguished Professor of Pathology and Adjunct Professor of Ophthalmology and Pharmacology at University of California, San Diego. He is also the Hildyard Endowed Chair in Eye Disease. His main research interests are the biology of angiogenesis and its regulators. His discovery of VEGF as a key mediator of angiogenesis associated with intraocular neovascular syndromes resulted in the clinical development of ranibizumab, which was approved as the first therapy for wet AMD. He was awarded the Lasker–DeBakey Clinical Medical Research Award in 2010
  • Wenchao Song, Ph.D., is a Professor of Pharmacology in the Department of Systems Pharmacology and Translational Therapeutics at the Perelman School of Medicine of the University of Pennsylvania. Dr. Song is an internationally renowned expert on complement biology. His research group pioneered studies of mouse models of complement-mediated diseases. His work has helped reveal fundamental knowledge of how complement is regulated in vivo, with translational relevance to anti-complement therapeutics

Recent Highlights in Large Market Ophthalmology Portfolio

• 4D-150 for wet AMD:
  • Presented positive interim data from the ongoing PRISM Phase 1/2 clinical trial at 4D-150 Wet AMD Development Day:
    • Robust and durable reduction in anti-VEGF injection treatment burden observed in all populations studied with the planned Phase 3 dose (3E10 vg/eye) through up to 52 weeks, including overall reduction of 83% in severe population and Kaplan-Meier method estimated 52-week injection-free rates of 70% and 87% in broad and recently diagnosed populations, respectively
    • Strong and sustained disease control achieved: stable retinal anatomy with fewer fluctuations and stable visual acuity
    • 4D-150 continues to be safe and well tolerated with rate of IOI numerically similar to that reported for approved anti-VEGF agents and 99% of patients completing topical steroid prophylaxis taper on schedule
  • Presented design of 4FRONT-1 Phase 3 clinical trial at its 4D-150 Wet AMD Development Day:
    • First study in global 4FRONT Phase 3 development program comparing a single dose of 4D-150 3E10 vg/eye to on-label aflibercept 2mg Q8 weeks

Q3 2024 Financial Results

Cash position: Cash, cash equivalents and marketable securities were $551 million as of September 30, 2024. We currently expect cash, cash equivalents and marketable securities to be sufficient to fund planned operations at least into the first half of 2027.

R&D Expenses: Research and development expenses were $38.5 million for the third quarter of 2024, as compared to $25.1 million for the third quarter of 2023. This increase was driven by the progression of our existing clinical trials, primarily Phase 2 4D-150 trials 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 $12.7 million for the third quarter of 2024, as compared to $9.1 million for the third quarter of 2023.

Net Loss: Net loss was $43.8 million for the third quarter of 2024, as compared to net loss of $10.3 million for the third quarter of 2023.
