EMERYVILLE, Calif., May 08, 2025 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (Nasdaq: FDMT, 4DMT or the Company), a leading late-stage biotechnology company advancing durable and disease-targeted therapeutics with potential to transform treatment paradigms and provide unprecedented benefits to patients, today reported Q1 2025 financial results, provided operational highlights and outlined expected upcoming milestones.

“The first quarter of 2025 marked a pivotal moment for 4DMT as we focused our pipeline on our highest value programs, 4D-150 and 4D-710, reported compelling 4D-150 Phase 2 results in wet age-related macular degeneration (wet AMD) and diabetic macular edema (DME), and initiated our first 4D-150 Phase 3 clinical trial 4FRONT-1 in wet AMD,” said David Kirn, M.D., Co-founder and Chief Executive Officer of 4DMT. “With strong Phase 1/2 data, optimized Phase 3 trial design, and a world-class leadership team, we are well positioned to execute on our mission to dramatically improve lives and outcomes for patients living with retinal vascular diseases with 4D-150, a backbone therapy designed to provide long-lasting relief from frequent and burdensome injections. Our strong balance sheet provides us an expected operational runway into 2028, enabling us to deliver topline results from both wet AMD Phase 3 clinical trials in H2 2027 without raising additional capital. We look forward to sharing data and programmatic updates in H2 2025 for both our 4D-150 program in wet AMD and DME and our 4D-710 program in cystic fibrosis lung disease.”

Recent Corporate Highlights

• Focused Pipeline and Extended Cash Runway
  • Identified core programs: 4D-150 for wet AMD and DME and 4D-710 for cystic fibrosis (CF) lung disease
  • Paused significant additional capital allocation and investment, pending additional financing or partnerships, for 4D-175 for geographic atrophy, 4D-725 for alpha-1 antitrypsin deficiency lung disease, and 4D-310 for Fabry disease cardiomyopathy
  • Terminated development of 4D-110 for choroideremia and 4D-125 for X-linked retinitis pigmentosa
  • Paused investment into new preclinical product candidates
  • As a result, cash runway was extended into 2028 and includes full execution and topline 52-week data from 4FRONT-1 and 4FRONT-2 Phase 3 clinical trials in wet AMD, as well as ongoing Phase 1 & 2 clinical development of 4D-150 in DME and 4D-710 in CF

Recent Highlights and Expected Milestones in Large Market Ophthalmology Portfolio

• 4D-150 for wet AMD:
  • 4FRONT Global Phase 3 Program :
    • Enrolled first patients in North American clinical trial, 4FRONT-1
    • Global clinical trial, 4FRONT-2, expected to initiate in Q3 2025
    • Primary endpoint 52-week topline data from both 4FRONT-1 and 4FRONT-2 expected in H2 2027
  • PRISM Phase 1/2 Clinical Trial :
    • Presented positive 52-week results from 3E10 vg/eye (Phase 3 dose) arm of Phase 2b Population Extension cohort (best available data as of January 15, 2025):
      • In the broad population (n=30), 3E10 vg/eye demonstrated 83% reduction in injection burden vs. projected on-label aflibercept 2 mg Q8W; 70% of patients required 0-1 supplemental injection and 57% were injection-free
      • In the recently diagnosed subgroup (n=15), which most resembles the Phase 3 4FRONT-1 and 4FRONT-2 patient populations, 3E10 vg/eye demonstrated 94% reduction in injection burden vs. projected on-label aflibercept 2 mg Q8W; 87% of patients required 0-1 supplemental injection and 80% were injection-free
      • Improved and maintained best corrected visual acuity (BCVA) and central subfield thickness (CST) with fewer fluctuations
      • 4D-150 continues to be well tolerated during up to three years of follow-up in all patients (n=71) treated with 3E10 vg/eye dose, with the highest 4D-150-related intraocular inflammation (SUN/NEI scales) observed as mild (1+) vitreous cells at a single timepoint in 2.8% (2 of 71) of patients
    • Presented biomarker data from patients treated with 3E10 vg/eye in Phase 1/2a and 2b cohorts supporting ongoing multi-year durability with stable aqueous humor aflibercept concentrations consistently within projected therapeutic range with up to two years of follow-up (best available data as of November 20, 2024)
    • 2-year data from Phase 1/2a and 18-month data from Phase 2b cohorts expected in Q4 2025

      • Post-3 loading doses of aflibercept, 3E10 vg/eye demonstrated strong signals of clinical activity, with sustained gain of BCVA of +8.4 letters and reduction of CST of -194 µm from baseline
      • 3E10 vg/eye achieved an 86% reduction in injection burden vs. projected on-label aflibercept 2 mg Q8W and dose response, with 61% reduction vs. the lower-dose cohort at 1E10 vg/eye, with 0.6 mean supplemental injections per patient, with stringent supplemental injection criteria
    • 52-week interim data update expected at a scientific conference in Q3 2025
  • Phase 3 Planning :
    • Announced alignment with U.S. Food and Drug Administration (FDA) on registrational path
      • FDA aligned with proposed single Phase 3 clinical trial being acceptable for the basis of a BLA submission for 4D-150 in DME, based on review of data from SPECTRA and PRISM (wet AMD) clinical trials to date and planned global Phase 3 clinical development program for wet AMD
      • Per FDA feedback, the Company may proceed to Phase 3 (SPECTRA Part 2 no longer needed), and the FDA is aligned with key design elements of a Phase 3 clinical trial with approximately 300-400 patients total with a primary endpoint of BCVA noninferiority vs. on-label aflibercept 2 mg (5 loading doses and Q8W) and revised supplemental injection criteria
    • Received Regenerative Medicine Advanced Therapy (RMAT) designation from FDA, validating 4D-150’s potential to address the significant unmet medical needs in treating DME
    • Next steps pending final FDA and EMA alignment on Phase 3 clinical trial design and funding pathway

Q1 2025 Financial Results

Cash position: Cash, cash equivalents, and marketable securities were $458 million as of March 31, 2025, as compared to $505 million as of December 31, 2024. The net decrease in cash was primarily a result of cash used in operations. We currently expect cash, cash equivalents, and marketable securities to be sufficient to fund planned operations into 2028.

R&D Expenses: Research and development expenses were $40.7 million for the first quarter of 2025, as compared to $27.9 million for the first quarter of 2024. This increase was primarily driven by the initiation of our first Phase 3 clinical trial of 4D-150 in wet AMD, including increased personnel and professional services to support Phase 3 development.

G&A Expenses: General and administrative expenses were $12.9 million for the first quarter of 2025, as compared to $10.3 million for the first quarter of 2024. This increase was primarily driven by professional services.

Net Loss: Net loss was $48.0 million for the first quarter of 2025, as compared to net loss of $32.4 million for the first quarter of 2024.
