EMERYVILLE, Calif., May 10, 2023 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (Nasdaq: FDMT, 4DMT, or the Company) a clinical-stage biotherapeutics company harnessing the power of directed evolution for genetic medicines targeting large market diseases, today reported first quarter 2023 financial results and provided operational highlights.

“We are pleased with the progress of our large market ophthalmology portfolio this year. In April at ARVO, we released positive interim clinical data on all three dose cohorts in the Dose Exploration stage of our Phase 1/2 PRISM clinical trial of 4D-150 for the treatment of wet AMD. We observed excellent tolerability and clinical activity in these high anti-VEGF need patients that we believe support a differentiated profile. We are excited to see faster than expected enrollment of the Phase 2 Dose Expansion stage of the PRISM trial and believe this highlights the belief by investigators that 4D-150 has potential to be a transformative treatment for patients with wet AMD. We also announced the acquisition of the rights and know-how for sCFH from Aevitas for use in our preclinical product candidate 4D-175 for treatment of GA,” said David Kirn, M.D., Co-founder and Chief Executive Officer of 4DMT. “We believe we have the opportunity to build a franchise in large market ophthalmology with 4D-150 for the treatment of wet AMD and diabetic macular edema (DME) and 4D-175 in for GA, each using our retinotropic vector R100.   Our capital-efficient operations and strong cash position are expected to support operations into the first half of 2026.”

Recent Highlights in Large Market Ophthalmology Portfolio

• Significant progress advancing the 4D-150 program for the intravitreal treatment of patients with wet AMD and with DME
  • Presented positive interim data from the three dose cohorts studied (3E10, 1E10, and 6E9 vg/eye; n=5 each) in the Dose Exploration stage of the Phase 1/2 PRISM clinical trial for wet AMD in April at the ARVO 2023 Conference
    • All three doses were well-tolerated and demonstrated clinical activity
    • Dose response observed in favor of 3E10 vg/eye vs lower doses of 1E10 and 6E9 vg/eye
    • In the 3E10 vg/eye cohort, 4 of 4 (100%) of Phase 2 BCVA-eligible patients remained injection-free at 36 weeks with a mean reduction in central subfield thickness (CST) of 72µm
  • Enrollment in Phase 2 Dose Expansion (n=50) stage of the PRISM is more than 50% completed
• Acquired the rights and know-how for sCFH from Aevitas Therapeutics, Inc. and announced sCFH as payload for 4D-175 product candidate for GA
  

Expected Upcoming Milestones

• 4D-150 for Wet AMD and DME:
  • Enrollment of the Phase 2 randomized Dose Expansion stage of the PRISM clinical trial expected to complete in Q3 2023
  • Initial interim 4D-150 for wet AMD Phase 2 data expected in H1 2024
  • Enrollment of the Phase 2 SPECTRA clinical trial for DME expected to begin in Q3 2023

  • Program update expected in 2H 2023

Q1 2023 Financial Results

Cash and Cash Equivalents and Marketable Securities: Cash and cash equivalents and marketable securities were $202 million as of March 31, 2023, as compared to $218 million as of December 31, 2022. The decrease in cash was primarily a result of cash used in operations, which was partially offset by $9.6M of net proceeds from the sale of shares pursuant to our Open Market Sales Agreement. In addition, in May 2023 we completed a public offering of common stock that resulted in us receiving net proceeds of approximately $129 million. We currently expect cash and cash equivalents, inclusive of net proceeds from the May 2023 offering, to be sufficient to fund operations into the first half of half of 2026.

R&D Expenses: Research and development expenses were $22.4 million for the quarter ended March 31, 2023 as compared to $19.4 million for the first quarter of 2022. This increase was driven by the progression of our existing clinical trials, primarily 4D-150, along with increased payroll and stock-based compensation expense.

G&A Expenses: General and administrative expenses were $8.0 million for the quarter ended March 31, 2023 as compared to $8.2 million for the first quarter of 2022.
Net Loss: Net loss was $28.7 million for the quarter ended March 31, 2023, as compared to $26.3 million for the first quarter of 2022.

About 4DMT

4DMT is a clinical-stage biotherapeutics company harnessing the power of directed evolution for genetic medicines targeting large market diseases. 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 (Fabry disease cardiomyopathy). 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.
