Summary

This trial will test the safety of ATSN-201, a one-time eye injection, in males aged 6 and older with a specific eye condition called XLRS.

Who is the study for?
This trial is for male patients with X-linked retinoschisis (XLRS) due to RS1 mutations. Adults must be between 18 and 64 years old, while children should be aged 6 to under 18. Participants need a specific level of vision clarity. Those who've had previous eye gene therapy or certain eye conditions/surgeries are excluded.
What is being tested?
The study tests the safety and effects of ATSN-201, a gene therapy for males with XLRS. It will involve different age groups (cohorts) to assess how well they tolerate this potential new treatment.
What are the potential side effects?
While not explicitly listed, side effects may include typical risks associated with gene therapies such as immune reactions, discomfort at injection site, and potential worsening of vision or other ocular issues.
