EMERYVILLE, Calif., May 09, 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 first quarter 2024 financial results and provided operational highlights.

“The first quarter of 2024 kicks off another transformative year for 4DMT with exceptional progress across our product pipeline and platform in multiple therapeutic areas, particularly our lead program 4D-150 in large market VEGF-driven retinal diseases,” said David Kirn, M.D., Co-founder and Chief Executive Officer of 4DMT. “With robust clinical activity from 4D-150 demonstrated in our initial interim 24-week results from the Phase 2 PRISM Dose Expansion cohort in the severe disease activity wet AMD patient population, we set the stage for additional important data readouts in 2024, including 24-week results from the Phase 2 PRISM Population Extension cohort in the broader wet AMD patient population expected to be announced at ASRS in July and 24-week results from the Phase 2 SPECTRA Dose Confirmation cohort in DME expected to be announced in the fourth quarter. We believe the emerging profile of 4D-150 shows its potential to be the best-in-class, long-acting genetic medicine for broad market use in VEGF-driven retinal diseases, and we look forward to completing alignment with the FDA and EMA to rapidly advance 4D-150 into its first pivotal trial for global development. Building on the success of intravitreal R100, we are also encouraged by the preclinical results from 4D-175 that we shared today at the 2024 Association for Research in Vision and Ophthalmology (ARVO) Annual Scientific Meeting and are looking forward to bringing the program into the clinic for treatment of geographic atrophy in the second half of the year, demonstrating the power of our modular vectors and product engine. In addition, we continue to advance towards important milestones for 4D-710 for cystic fibrosis, 4D-725 for A1AT deficiency and 4D-310 for Fabry disease cardiomyopathy. Our successful financing puts us in a strong position to execute on all our corporate objectives, with expected cash runway into the first half of 2027.”

Q1 2024 Financial Results

Cash and Cash Equivalents and Marketable Securities: Cash and cash equivalents and marketable securities were $589 million as of March 31, 2024, as compared to $299 million as of December 31, 2023. The net increase in cash was primarily a result of cash inflows from approximately $316 million of net proceeds from our public offering of common stock completed in February including partial exercise of underwriters’ option to purchase additional shares. We currently expect cash and cash equivalents to be sufficient to fund operations into the first half of 2027.

R&D Expenses: Research and development expenses were $27.9 million for the first quarter of 2024, as compared to $22.4 million for the first quarter of 2023. 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 $10.3 million for the first quarter of 2024, as compared to $8.0 million for the first quarter of 2023.

Net Loss: Net loss was $32.4 million for the first quarter of 2024, as compared to net loss of $28.7 million for the first quarter of 2023.
