Study Endpoints

Primary Endpoints

The proportion of participants with a ≥15 letter increase from baseline in LLVA
Day 0 - Month 12

LLVA(Low Luminance Visual Acuity) will be determined by adding a neutral density filter to the refraction using standard ETDRS (Early Treatment of Diabetic Retinopathy) visual acuity or tumbling "E" chart

Secondary Endpoints

Change from baseline in LLVA (First Key Secondary Endpoint)
Day 0 - Month 12
Change from baseline in mean sensitivity across the whole grid, as measured by MAIA (Second Key Secondary Endpoint) microperimetry
Day 0 - Month 12
Change from baseline in full-field stimulus threshold (FST) (Third Key Secondary Endpoint)
Day 0 - Month 12

Frequently asked questions about rAAV2tYF-GRK1-hRPGRco

What is rAAV2tYF-GRK1-hRPGRco used for?

rAAV2tYF-GRK1-hRPGRco is an investigational gene therapy being developed for X-Linked Retinitis Pigmentosa, a rare inherited retinal disease. It is designed to deliver a functional RPGR gene to retinal cells via subretinal injection. The drug is currently in Phase 2 clinical development and has not been approved by regulatory authorities.

How does rAAV2tYF-GRK1-hRPGRco work?

rAAV2tYF-GRK1-hRPGRco works by delivering a copy of the RPGR gene using an adeno-associated viral vector. The vector is engineered to target retinal cells, where the gene is intended to produce the RPGR protein that is deficient or defective in X-Linked Retinitis Pigmentosa. This approach aims to restore retinal cell function and slow disease progression.

Who is developing rAAV2tYF-GRK1-hRPGRco?

rAAV2tYF-GRK1-hRPGRco is being developed by Elevance Health, Inc., a company traded on the New York Stock Exchange under the ticker ELV. The drug is in Phase 2 clinical trials for X-Linked Retinitis Pigmentosa.

What phase is rAAV2tYF-GRK1-hRPGRco in?

rAAV2tYF-GRK1-hRPGRco is currently in Phase 2 clinical development. It is an investigational drug and has not been approved by the FDA or other regulatory agencies. The ongoing Phase 2 trial is active but not recruiting participants, with an enrollment target of 85 patients.

What clinical trials is rAAV2tYF-GRK1-hRPGRco in?

rAAV2tYF-GRK1-hRPGRco is being evaluated in a Phase 2 clinical trial registered as NCT04850118. This trial is assessing the safety and efficacy of a single subretinal injection of the drug in participants with X-Linked Retinitis Pigmentosa. The study is active but not recruiting, with 85 enrolled participants across the United States, Australia, Canada, and the United Kingdom.

Is rAAV2tYF-GRK1-hRPGRco the same as AGTC-501?

Yes, rAAV2tYF-GRK1-hRPGRco is also known as AGTC-501. The Phase 2 clinical trial NCT04850118 is titled 'A Clinical Trial Evaluating the Safety and Efficacy of a Single Subretinal Injection of AGTC-501 in Participants With XLRP,' confirming that both names refer to the same investigational gene therapy.
