4DMT Announces RMAT Designation Granted by FDA for 4D-150 for DME

May 01, 2025 08:00 ET | Source: 4D Molecular Therapeutics, Inc. EMERYVILLE, Calif., May 01, 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 announced that the U.S. Food and Drug Administration (FDA) has granted the Regenerative Medicine Advanced Therapy (RMAT) designation to 4D-150 for the treatment of diabetic macular edema (DME). “This milestone validates the potential of 4D-150 to address the significant unmet needs of patients with DME, a second large market retinal vascular disease indication after wet age-related macular degeneration (wet AMD),” said David Kirn, M.D., Co-founder and Chief Executive Officer of 4DMT. “The RMAT designation is based on the review of our results to-date from our ongoing 4D-150 SPECTRA DME study, underscoring the potential of 4D-150 to sustain visual acuity improvements while dramatically reducing treatment burden for patients. This designation in DME follows the RMAT designation granted for 4D-150 in wet AMD, and to our knowledge, 4D-150 is the first investigational medicine to be granted the designation in both indications. We look forward to continuing our ongoing collaboration with the FDA to advance 4D-150 into Phase 3 development with an aligned-upon single Phase 3 trial for approval in DME, combined with our two wet AMD 4FRONT Phase 3 clinical trials.” RMAT designation is part of the 21st Century Cures Act. The program was created to expedite the development and review of regenerative medicine therapies intended to treat, modify, reverse or cure a serious condition. Receiving RMAT designation offers sponsor companies all the benefits of the fast track and breakthrough therapy designation programs, allowing for early, close and frequent interactions with the FDA with the goal of expediting drug development. About 4D-150 4D-150 is a potential backbone therapy that is designed to provide multi-year sustained delivery of anti-VEGF (aflibercept and anti-VEGF-C) from the retina with a single, safe, intravitreal injection. 4D-150 utilizes our customized and evolved intravitreal vector, R100, which was invented at 4DMT through our proprietary Therapeutic Vector Evolution platform. 4D-150 is being developed for wet AMD and DME, which both affect millions of patients globally, with the goal of freeing patients from burdensome injections while preserving vision. About DME DME, or diabetic macular edema, is a complication of diabetic retinopathy and is a highly prevalent disease with significant unmet medical need and poor treatment adherence. It is estimated that there are approximately one million individuals with DME in the U.S. according to published data. DME is characterized by inflammation and swelling in the macula due to leakage from blood vessels, which can lead to vision loss. DME is typically treated with intravitreal anti-VEGF agents administered approximately every 4-12 weeks, although patient compliance with therapy is poor and results in high unmet medical need. About 4DMT 4DMT is a leading late-stage biotechnology company advancing durable and disease-targeted therapeutics with potential to transform treatment paradigms and provide unprecedented benefits to patients. Our lead product candidate 4D-150 is designed to be a backbone therapy forming the foundation of treatment of blinding retinal vascular diseases by providing multi-year sustained delivery of anti-VEGF (aflibercept and anti-VEGF-C) with a single, safe, intravitreal injection, which substantially reduces the treatment burden associated with current bolus injections. Our lead indication for 4D-150 is wet age-related macular degeneration, which is currently in Phase 3 development, and second indication is diabetic macular edema. Our second product candidate is 4D-710, which is the first known genetic medicine to demonstrate successful delivery and expression of the CFTR transgene in the lungs of people with cystic fibrosis after aerosol delivery. 4D Molecular Therapeutics™, 4DMT™, Therapeutic Vector Evolution™, and the 4DMT logo are trademarks of 4DMT.
