4D Molecular Therapeutics Reports Third Quarter 2022 Financial Results

- Interim clinical trial data from 4DMT’s Phase 1/2 clinical trial of 4D-710 for the treatment of cystic fibrosis lung disease was presented at North American Cystic Fibrosis Conference on November 3, 2022

- Cash, cash equivalents and marketable securities sufficient to fund operations into the first half of 2025

EMERYVILLE, Calif., Nov. 09, 2022 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics, Inc. (Nasdaq: FDMT), a clinical-stage biotherapeutics company harnessing the power of directed evolution for targeted genetic medicines, today reported third quarter 2022 financial results.

On November 3, 2022, interim clinical data from patients enrolled in cohort 1 of 4DMT’s Phase 1/2 clinical trial of 4D-710 for the treatment of cystic fibrosis lung disease was presented at the North American Cystic Fibrosis Conference, which demonstrated safety and tolerability with no 4D-710-related adverse events following aerosol delivery. Analyses of 11 total lung biopsies and brushings (Week 4) demonstrated widespread delivery and expression of the 4D-710 CFTRΔR transgene in all samples across all three patients’ lungs. Levels of transgene expression were in a range that was predicted to be associated with clinical benefit. The 4D-710 product candidate comprises the proprietary synthetic aerosol delivered vector A101 that was invented at 4DMT.

"We are encouraged by the interim clinical data we have released from our aerosol delivered 4D-710 program for the treatment of cystic fibrosis lung disease. We have now demonstrated potential safety, tolerability, and clinical activity with three different proprietary synthetic AAV-derived vectors, each delivered by a routine route of administration, that we invented through our Therapeutic Vector Evolution platform. These clinical data illustrate the potential of this platform to invent optimized vectors for our genetic medicines in multiple therapeutic areas. We look forward to further patient assessments, and to enrolling additional patients onto the 4D-710 clinical trial to continue the progress of our 4D-710 product candidate,” said David Kirn, M.D., Co-founder, and Chief Executive Officer of 4DMT. Dr. Kirn added, “During 2022, we have maintained our discipline and focus on efficient cash utilization with current cash available to support our planned operations into the first half of 2025.”

Third Quarter 2022 Financial Results

Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities were $239 million as of September 30, 2022. We expect cash, cash equivalents and marketable securities to be sufficient to fund planned operations into the first half of 2025.

Revenue: Total revenue for the quarter ended September 30, 2022, was $0.5 million, as compared to $1.4 million for the quarter ended September 30, 2021.

R&D Expenses: Research and development expenses were $18.9 million for the quarter ended September 30, 2022, as compared to $15.8 million for the quarter ended September 30, 2021. This increase was primarily driven by the progression of our 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 $8.1 million for the quarter ended September 30, 2022, as compared to $8.2 million for the quarter ended September 30, 2021.

Net Loss: Net loss was $25.7 million for the quarter ended September 30, 2022, as compared to $22.2 million for the quarter ended September 30, 2021. This increase in net loss was primarily driven by increased research and development expenses associated with the progression of our clinical product candidates, including 4D-150 for wet AMD, 4D-310 for Fabry disease and 4D-710 for cystic fibrosis lung disease.

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.
