EMERYVILLE, Calif., Aug. 11, 2022 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics, Inc. (Nasdaq: FDMT), a clinical-stage biotherapeutics company harnessing the power of directed evolution for targeted genetic medicines, reported second quarter 2022 financial results and provided a 4D-310 program update.

"Maintaining our momentum from the first quarter, we continued to execute towards our clinical and corporate milestones, including progress across all of our five clinical-stage product candidates,” said David Kirn, M.D., Co-founder, President and Chief Executive Officer of 4DMT. “In addition, the protocol amendment for the 4D-310 Phase 1/2 clinical trial in Fabry disease will expand access to include female patients, a large and significantly affected patient population with Fabry disease. We have maintained our focus on efficient cash utilization, with current cash available to support our operations into the first half of 2025. Our team is committed to relentless execution as we make progress toward key clinical data readouts in the first half of 2023 and beyond.”

Update on 4D-310 Phase 1/2 Clinical Trial for Fabry Disease

In June 2022, 4DMT filed a protocol amendment with the U.S. Food and Drug Administration (FDA) for the ongoing Phase 1/2 clinical trial of 4D-310 for Fabry disease. The protocol amendment is intended to expand the eligible patient population, including the addition of female Fabry patients with symptomatic disease. The inclusion of female patients in the phase 1/2 clinical trial was supported by clinical experience to-date, as well as a GLP toxicology study in female mice.   The company continues to expect to provide a clinical data update on 4D-310 in the 1st half of 2023.

Second Quarter 2022 Financial Results

Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities were $261.6 million as of June 30, 2022. We expect cash, cash equivalents and marketable securities to be sufficient to fund operations into the first half of 2025.

Revenue: Total revenue for the quarter ended June 30, 2022, was $0.2 million, as compared to $14.6 million for the quarter ended June 30, 2021.

R&D Expenses: Research and development expenses were $20.4 million for the quarter ended June 30, 2022, as compared to $15.2 million for the quarter ended June 30, 2021. This increase was primarily driven by the progression of our five existing clinical product candidates, including 4D-150 (for wet AMD), 4D-310 (for Fabry disease) and 4D-710 (for cystic fibrosis lung disease).

G&A Expenses: General and administrative expenses were $8.2 million for the quarter ended June 30, 2022, as compared to $7.0 million for the quarter ended June 30, 2021. This increase was primarily due to increased payroll, stock-based compensation, insurance, and professional service expenses.

Net Loss: Net loss was $28.1 million for the quarter ended June 30, 2022, as compared to $7.6 million for the quarter ended June 30, 2021.

About 4DMT

4DMT is a clinical-stage biotherapeutics company harnessing the power of directed evolution for targeted genetic medicines. 4DMT seeks to unlock the full potential of genetic medicines using its platform, Therapeutic Vector Evolution, which combines the power of directed evolution with approximately one billion synthetic capsid sequences to invent targeted and evolved vectors for use in our products. The company is initially focused on five clinical-stage products in three therapeutic areas for both rare and large market diseases: ophthalmology, cardiology (including Fabry disease) and pulmonology. The 4DMT targeted and evolved vectors are 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. The five 4DMT product candidates in clinical development are: 4D-150 for wet AMD, 4D-310 for Fabry disease, 4D-710 for cystic fibrosis, 4D-125 for XLRP, and 4D-110 for choroideremia.

4D-150, 4D-310, 4D-710, 4D-125, and 4D-110 are in clinical trials 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-310, 4D-710, 4D-125, and 4D-110 for the therapeutic use for which they are being studied. 4D Molecular Therapeutics™, 4DMT™, Therapeutic Vector Evolution™, and the 4DMT logo are trademarks of 4DMT.
