Frequently asked questions about 4D-150

What is 4D-150?

4D-150 is an investigational intravitreal therapy developed by 4D Molecular Therapeutics for retinal diseases driven by VEGF. It is being studied in diabetic macular edema and macular neovascularization secondary to age-related macular degeneration, including neovascular (wet) AMD. It is a monoclonal antibody-based product given as a single intravitreal injection in the trials listed.

What is 4D-150 used for in diabetic macular edema?

4D-150 is being studied as a treatment for diabetic macular edema, a VEGF-driven retinal condition. A Phase 3 trial, NCT07867080, is recruiting adults 18 years and older with DME across the United States, China, and Japan, with planned enrollment of 514 participants. An earlier Phase 2 trial in DME and diabetic retinopathy, NCT05930561, enrolled 72 patients.

What does 4D-150 target?

4D-150 targets VEGF, the vascular endothelial growth factor protein that drives abnormal blood vessel growth and leakage in retinal disease. By binding VEGF, the monoclonal antibody aims to counter the neovascularization and fluid accumulation seen in diabetic macular edema and neovascular age-related macular degeneration.

Who is developing 4D-150?

4D-150 is being developed by 4D Molecular Therapeutics, Inc., which trades under the ticker FDMT. The company is running the clinical program for the asset in ophthalmology, with Phase 3 trials underway in diabetic macular edema and neovascular age-related macular degeneration.

What phase is 4D-150 in?

4D-150 is in Phase 3 clinical development. Two Phase 3 trials are currently recruiting: NCT07867080 in diabetic macular edema and NCT07064759 in neovascular age-related macular degeneration. A third Phase 3 trial, NCT06864988, is active but no longer recruiting. 4D-150 holds an RMAT designation from the FDA and remains investigational.

What clinical trials is 4D-150 in?

4D-150 is being evaluated in four registered trials. Phase 3 studies include NCT07867080 in diabetic macular edema, NCT07064759 in neovascular AMD across 18 countries, and NCT06864988 in macular neovascularization secondary to AMD in the United States and Canada. A Phase 2 trial, NCT05930561, studied DME and diabetic retinopathy.

Is 4D-150 the same as 4D-150 IVT?

Yes. 4D-150 IVT is another name for 4D-150, referring to intravitreal administration of the therapy. Dose-specific labels such as 4D-150 IVT (3E10 vg/eye) and 4D-150 IVT (3x10^10 vg) describe the same investigational product given at different vector genome doses per eye.
