Study Endpoints

Primary Endpoints

Change in functional vision from baseline to week 52 in pooled analysis when study eyes in treatment group were compared to study eyes in untreated control
52 weeks

Change in functional vision from baseline to week 52 in pooled analysis from retinitis pigmentosa subjects when study eyes in treatment group were compared to study eyes in untreated control, as measured by the ability of a study participant to navigate through a maze in Luminance Dependent Navigation Assessment (LDNA)

Secondary Endpoints

Change in functional vision from baseline to week 52 in all the treated eyes from RP subjects (study eyes + fellow treated eyes) when compared to all the eyes (study eyes and fellow eyes) in untreated control group
52 weeks
Change from Baseline in visual function in patients with retinitis pigmentosa when treatment group were compared to untreated controls
52 weeks
Change from baseline in LDNA Lux-level results in treated subjects when compared to the untreated controls

Frequently asked questions about Sub-Retinal Administration of OCU400-301

What is Sub-Retinal Administration of OCU400-301 used for?

Sub-Retinal Administration of OCU400-301 is an investigational gene therapy being developed for the treatment of Retinitis Pigmentosa, a group of inherited retinal diseases that cause progressive vision loss. It is administered via sub-retinal injection and is currently in Phase 3 clinical development.

What does Sub-Retinal Administration of OCU400-301 target?

Sub-Retinal Administration of OCU400-301 targets the NR2E3 gene, which plays a role in retinal function. By delivering a functional copy of this gene, the therapy aims to address the underlying genetic cause of Retinitis Pigmentosa in affected patients.

Who is developing Sub-Retinal Administration of OCU400-301?

Sub-Retinal Administration of OCU400-301 is being developed by Ocugen, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol OCGN. The company is conducting a Phase 3 clinical trial to evaluate the therapy in patients with Retinitis Pigmentosa.

What phase is Sub-Retinal Administration of OCU400-301 in?

Sub-Retinal Administration of OCU400-301 is currently in Phase 3 clinical development. It is an investigational therapy and has not yet been approved by regulatory authorities. The therapy has received a Regenerative Medicine Advanced Therapy (RMAT) designation from the FDA.

What clinical trials is Sub-Retinal Administration of OCU400-301 in?

Sub-Retinal Administration of OCU400-301 is being evaluated in a Phase 3 clinical trial with the identifier NCT06388200. This active, not recruiting study is enrolling approximately 140 participants with Retinitis Pigmentosa across the United States and Canada, with a minimum age of 3 years.
