An Open Label, Multi-centre, Phase I/II Dose Escalation Trial of a Recombinant Adeno-associated Virus Vector (AAV2/5-hRKp.RPGR) for Gene Therapy of Adults and Children With X-linked Retinitis Pigmentosa Owing to Defects in Retinitis Pigmentosa GTPase Regulator (RPGR)

In Brief

A Phase 2 clinical trial evaluating AAV5-RPGR for X-Linked Retinitis Pigmentosa. Completed, enrolled 49 participants across 5 sites in 2 countries.

Detailed Summary

Phase 1 of the study is a dose escalation of the subretinal administration of AAV5-hRKp.RPGR vector to assess the safety of this vector in participants with XLRP caused by mutations in RPGR. Participants enrolled in Phase 1 were assigned to a dose group based on when they enrolled (i.e., sequential assignment). Phase 2 of the study is a cohort expansion of the subretinal administration of AAV5-hRKp.RPGR vector to assess the safety and efficacy of this vector in participants with XLRP caused by mutations in RPGR. Participants enrolled in Phase 2 were randomized to immediate or deferred treatment.
