4DMT Completes Enrollment for 4FRONT-2 Global Phase 3 Clinical Trial of 4D-150 in Wet AMD
Rhea-AI Summary
4D Molecular Therapeutics (Nasdaq: FDMT) completed global enrollment for its 4FRONT-2 Phase 3 trial of 4D-150 in wet AMD about four months ahead of projections and with over-enrollment (anticipated N>500). Final randomization is expected in Q3 2026, with 52-week topline data in H2 2027. 4FRONT-2 compares intravitreal 4D-150 to aflibercept 2 mg (Q8W), targeting non-inferiority in BCVA and reduced treatment burden. 4FRONT-1, a similar North American Phase 3 trial in treatment-naïve wet AMD, is underway with topline data expected in H1 2027.

FDMT was modestly higher pre-news, while Argus-linked peers showed mixed momentum (some sharply down, one notably up). This divergence from a mostly negative peer skew points to a stock-specific catalyst.
Previous Clinical trial Reports
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Feb 09 | Phase 3 enrollment | Positive | +1.0% | Completed 4FRONT-1 Phase 3 enrollment with over-enrollment in wet AMD. |
| Dec 17 | Interim CF data | Positive | -20.1% | Positive interim 4D-710 AEROW Phase 1 data in cystic fibrosis lung disease. |

| Oct 13 | CF funding, Phase 2 | Positive | +8.7% | CF Foundation funding and advancement of 4D-710 program toward later-stage trials. |
| Jul 31 | SPECTRA DME data | Positive | +42.7% | Positive 60-week SPECTRA DME results with strong efficacy and burden reduction. |
Clinical trial updates have generally produced positive stock moves, with one major negative reaction despite favorable data.
Historical Comparison
Clinical trial announcements for FDMT have averaged a 7.23% move, often positive. Today’s Phase 3 enrollment completion fits the pattern of meaningful clinical milestones driving investor focus.
Same-tag history shows steady progression for 4D-150 and 4D-710 from early data to Phase 3 readiness, with repeated demonstrations of burden reduction and durability supporting a backbone-therapy strategy.
Regulatory & Risk Context
Short interest is elevated, indicating meaningful bearish positioning and the potential for heightened volatility or squeeze dynamics if sentiment shifts rapidly.
An effective S-3 shelf for up to $400.0 million gives FDMT flexibility to issue securities over time, which can support funding Phase 3 programs but may introduce future dilution depending on how it is used.
Market Pulse Summary
This announcement adds another Phase 3 milestone for 4D-150, with two 52-week readouts expected by 2027. Historical clinical updates have usually helped the stock, but elevated short interest and an available shelf mean financing choices and data quality remain key watchpoints.

EMERYVILLE, Calif., June 29, 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-2, the second Phase 3 clinical trial in our global program, evaluating 4D-150 in patients with wet age-related macular degeneration (wet AMD).
“Completing global enrollment in both 4FRONT-1 and 4FRONT-2 Phase 3 trials with over-enrollment and ahead of initial projections further validates 4D-150 as the potential cornerstone of a transformative, category-defining retina franchise at 4DMT,” said David Kirn, M.D., Co-founder, President and Chief Executive Officer of 4DMT. “The high enrollment rate across both 4FRONT-1 and 4FRONT-2 trials, predominantly in treatment-naïve patients, reflects the enthusiasm of patients and retina physicians for 4D-150, as well as the high unmet medical need for a vision-preserving durable backbone therapy in wet AMD. With two Phase 3 readouts expected in 2027 and initiation of a Phase 3 trial in diabetic macular edema in the third quarter of this year, we are rapidly advancing our vision of 4D-150 as the potential backbone therapy for patients with large-market retinal vascular diseases worldwide.”
“Wet AMD remains a leading cause of vision loss worldwide, and despite important advances in bolus anti-VEGF therapy, most patients still continue to face the real-world burden of frequent, lifelong injections and the associated risk of undertreatment and vision loss,” said Julie Clark, M.D., Chief Medical Officer of 4DMT. “The completion of enrollment in 4FRONT-2 brings us one step closer to confirming the clinical evidence that 4D-150 can meaningfully reduce treatment burden while preserving vision outcomes. We are deeply grateful to the patients, investigators, study coordinators and sites around the world who have made this trial possible.”
“As retina specialists, we see every day how the need for frequent intravitreal injections can create an unsustainable burden for many patients, caregivers and practices, and how missed or delayed treatments frequently put vision at risk,” said Patricio G. Schlottmann, M.D., Director of the Research Department at the Charles Ophthalmic Center, Ophthalmology Department Director at Organización Médica de Investigación in Buenos Aires, Argentina, member of the 4DMT Retinal Advisory Board and a principal investigator in the 4FRONT-2 clinical trial. “The vision for 4D-150 is compelling because it aims to move wet AMD care beyond repeated bolus injections toward durable, continuous disease control with a single intravitreal administration as the backbone treatment. Based on the clinical data generated to date, I believe 4D-150 has the potential to represent an important paradigm shift for patients and physicians if the ongoing Phase 3 program is successful. I look forward to the topline results in 2027.”
4FRONT-2 is a global Phase 3 multicenter, randomized, double-masked, aflibercept 2 mg (Q8W) comparator-controlled study of intravitreal 4D-150 in wet AMD that has enrolled both treatment-naïve and recently diagnosed treatment-experienced patients. 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 are eligible for supplemental aflibercept injections. 4FRONT-2 52-week topline data is expected in H2 2027. 4FRONT-1, the first 4D-150 wet AMD Phase 3 trial, is being conducted in North America evaluating treatment-naïve patients with an otherwise identical design to 4FRONT-2. 4FRONT-1 52-week topline data is expected in H1 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 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.
