About
This Phase 2 study is a non-randomized, open-label, study of the safety of AGTC-501 in participants with XLRP who have previously been treated with a full-length AAV vector-based gene therapy targeting RPGR protein.
Full description
This is a Phase 2, open-label, multicenter study to evaluate the safety of 2 doses of AGTC-501 administered as a single subretinal injection in participants with XLRP who have previously been treated with a full-length AAV vector-based gene therapy targeting RPGR protein.
The trial includes a screening period of up to 60 days and a 5 year study period.
Each participant will receive a single subretinal injection in their previously untreated eye. There will be 2 groups of 6 participants, each receiving one of two doses of the study treatment along with the standard corticosteroid regimen, followed by a third group of ~3-6 participants receiving the high dose but with a modified corticosteroid regimen. The first 6 participants will be enrolled in Group 1, followed by Group 2. Group 3 will open for enrollment after data has been reviewed by the DSMC. DSMC review will occur after all 6 Group 1 (high dose) study participants reach post-operative Month 1 and periodically throughout the study.
