EMERYVILLE, Calif., Feb. 09, 2026 (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 enrollment completion for 4FRONT-1, the first Phase 3 clinical trial evaluating 4D-150 in patients with wet age-related macular degeneration (wet AMD).

“The 4D-150 4FRONT-1 Phase 3 trial enrolled in 11 months in a treatment-naïve large market patient population. This is a landmark moment for 4DMT, for wet AMD patients and for our targeted and locally delivered genetic medicines,” said David Kirn, M.D., Co-founder, President, and Chief Executive Officer of 4DMT. “This high enrollment rate and over-enrollment in the front-line wet AMD setting reflects investigator and patient enthusiasm for 4D-150 as a potential backbone therapy. Remarkably, our team achieved this milestone in only four years after treating the first patient with 4D-150 in wet AMD. I want to extend my heartfelt congratulations to the entire 4DMT team for their tireless work, dedication, and execution in reaching this achievement. We look forward to continuing this momentum as we accelerate global enrollment in our second Phase 3 study, 4FRONT-2.”

“For far too long, wet AMD patients have faced the burden of relentless, lifelong repeated bolus injections and vision loss,” said Julie Clark, M.D., Chief Medical Officer of 4DMT. “Our vision is to fundamentally shift that paradigm, to bring forward a potential backbone therapy that meaningfully reduces treatment burden while sustaining vision outcomes. The rapid enrollment completion, driven by the enthusiasm for 4D-150 and data generated to date, energizes our entire organization as we work relentlessly toward completing global enrollment in 4FRONT-2 and prepare for topline data in H1 2027 from 4FRONT-1. I want to thank all our sites, study coordinators, and patients for their partnership and trust as we work toward our goal to drive a new standard of care for wet AMD.”

“As retina specialists, we routinely observe the challenges long-term intravitreal injection regimens pose for wet AMD patients and their association with suboptimal long-term vision outcomes in real-world practice,” said Arshad M. Khanani, M.D., M.A., FASRS, Director of Clinical Research at Sierra Eye Associates, Chair of the 4DMT Ophthalmology Advisory Board and a principal investigator in the 4FRONT-1 clinical trial. “Based on the long-term PRISM Phase 1/2 data, 4D-150 has the potential to significantly reduce treatment burden for patients with wet AMD, with a single in-office intravitreal injection providing sustained disease control. The rapid enrollment of 4FRONT-1 in treatment-naïve patients is particularly encouraging and reflects strong enthusiasm among physicians and patients for therapies that offer potentially safe, effective, and durable long-term disease control. This progress is also a testament to the strong execution and deep expertise of the 4DMT team in advancing Phase 3 clinical trials. I look forward to the continued advancement of the 4FRONT registrational program.”

4FRONT-1 is a Phase 3 multicenter, randomized, double-masked, aflibercept 2 mg (Q8W) comparator-controlled study of intravitreal 4D-150 in wet AMD. The primary endpoint is non-inferiority in the mean change from baseline in best corrected visual acuity (BCVA) at 52 weeks. The key secondary endpoint is treatment burden reduction comparing the number of aflibercept injections received in the 4D-150 arm versus the aflibercept comparator arm over 52 weeks. Patients in both arms will be eligible for supplemental aflibercept injections. 4FRONT-1 is evaluating treatment-naïve wet AMD patients at sites in North America. Topline primary endpoint data from 4FRONT-1 is expected in H1 2027. Our second Phase 3 for wet AMD, 4FRONT-2, is a global trial with an identical design to 4FRONT-1 except for enrolling both treatment-naïve and recently diagnosed treatment-experienced wet AMD patients. 4FRONT-2 is expected to complete enrollment in H2 2026 with topline primary endpoint data expected in H2 2027.

About 4D-150

4D-150 is a potential backbone therapy designed to provide multi-year, and potentially lifelong, sustained delivery of anti-VEGF biologics (aflibercept and anti-VEGF-C) within the retina following a single, safe, intravitreal injection. 4D-150 utilizes our customized and evolved intravitreal AAV vector, R100, which was invented at 4DMT through our proprietary Therapeutic Vector Evolution platform. 4D-150 is being developed for wet AMD and diabetic macular edema (DME), which both affect millions of patients globally, with the goal of freeing patients from burdensome injections while preserving vision.

About Wet AMD

Wet AMD, or wet age-related macular degeneration, is a highly prevalent disease, with more than 4 million individuals expected to be affected in the next five years in certain major markets, including the U.S., the EU and Japan. The disease also has a high incidence, with 200,000 individuals estimated to be newly diagnosed every year in the U.S. alone. Wet AMD is a type of macular degeneration in which abnormal blood vessels grow into the macula (macular neovascularization or MNV), the central area of the retina. MNV causes swelling and edema of the retina, bleeding and scarring, leading to visual distortion and reduced visual acuity. The proliferation and leakage of abnormal blood vessels is stimulated by VEGF. This process distorts and, without treatment, can potentially destroy central vision and may progress to blindness.

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 with retina diseases. The Company’s 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 biologics (aflibercept and anti-VEGF-C) with a single, safe, intravitreal injection, which substantially reduces the treatment burden associated with current bolus injections. The Company’s lead indication for 4D-150 is wet age-related macular degeneration, which is currently in Phase 3 development, and the second indication is diabetic macular edema. The Company’s 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.
