Frequently asked questions about RGX-314

What is RGX-314?

RGX-314 is an investigational gene therapy developed by REGENXBIO Inc. for retinal diseases. It is being studied in diabetic macular edema and neovascular age-related macular degeneration, also known as wet AMD. It is not yet approved and remains in clinical development.

What is RGX-314 used for in diabetic macular edema?

RGX-314 is being evaluated for center-involved diabetic macular edema, a form of DME in which fluid accumulates in the central retina. A Phase 2 trial, NCT06942520, is recruiting adults aged 25 and older in the United States to study the therapy in this indication.

Who makes RGX-314?

RGX-314 is developed by REGENXBIO Inc., a biotechnology company whose common stock trades on Nasdaq under the ticker symbol RGNX. REGENXBIO is the sponsor of the clinical programs evaluating RGX-314 in retinal disease.

What phase is RGX-314 in?

RGX-314 is in Phase 2 clinical development. A Phase 2 trial in center-involved diabetic macular edema is currently recruiting, while an earlier Phase 1 study in neovascular age-related macular degeneration has been completed. RGX-314 is investigational and has not been approved by the FDA.

What clinical trials is RGX-314 in?

RGX-314 has been studied in two registered trials. NCT06942520 is a recruiting Phase 2 trial in center-involved diabetic macular edema with an enrollment of 18. NCT03066258 was a completed Phase 1 safety and tolerability trial in neovascular AMD that enrolled 42 participants.

Is RGX-314 the same as RGX-314 Dose 1?

Yes. RGX-314 Dose 1 is an alternative name used for RGX-314, the investigational gene therapy from REGENXBIO. Searches for either name refer to the same clinical program in diabetic macular edema and neovascular age-related macular degeneration.
