Study Summary

This trial will test a new treatment for achromatopsia, a condition that causes decreased color vision. The study will measure the safety and effectiveness of the new treatment.

Who is the study for?
This trial is for males and females with a specific type of color blindness called CNGA3 achromatopsia. Participants must have mutations in both alleles of the CNGA3 gene, be at least 18 years old (or as young as 6 for certain groups), and have visual acuity not better than 20/80. Women who can bear children must test negative for pregnancy.Check my eligibility
What is being tested?
The trial tests AGTC-402, a new gene therapy given through an injection into one eye to treat achromatopsia caused by CNGA3 mutations. It's an open-label study, meaning everyone knows they're getting the treatment, focusing on safety first and then how well it works.See study design
What are the potential side effects?
While specific side effects are not listed here, typical risks may include reactions at the injection site, potential worsening of vision or eye discomfort, and general risks associated with subretinal injections.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is the recruitment phase of this study still open?

"Although it was initially published on August 3rd 2017 and received its last update on July 20th 2022, clinicaltrials.gov states that this medical study has concluded patient recruitment. However, there are 7 other trials still in the process of gathering participants."

Answered by AI

How widespread is the implementation of this research endeavor in U.S.-based medical facilities?

"Presently, this medical trial is taking place in 9 different sites. These locations are split between Houston, Boston and San Francisco with other 6 cities being involved too. It would be wise for prospective participants to pick the closest one to them in order to avoid any unnecessary travel."
