A Study to Investigate the Safety of OpCT-001 in Adults Who Have Primary Photoreceptor Disease (CLARICO)
brief summary
Study OpCT-001-101 is a Phase 1/2a first-in-human, multisite, 2-part interventional study to evaluate the safety, tolerability, and the effect on clinical outcomes of OpCT-001 in approximately 54 adults with primary photoreceptor (PR) disease. Phase 1 focuses on safety and features a dose-escalation design. Phase 2 is designed to gather additional safety data and assess the effect of OpCT-001 on measures of visual function, functional vision, and anatomic measures of engraftment in different clinical subgroups.
detailed description
Phase 1 of the study includes up to 4 planned dose levels to be administered across up to 4 cohorts. Participants are assigned to receive OpCT-001 in an open-label manner.
Dose escalation in Phase 1 is being conducted using a standard 3+3 scheme in which a total of up to 24 legally blind participants (\~3 to 6 per cohort) will receive OpCT-001. Phase 2 is planned to enroll a maximum of 15 participants per cohort in 2 cohorts to evaluate 2 dose levels of OpCT-001 that will be selected based on Phase 1 safety and tolerability data. Phase 2 participants will be randomized 1:1 to either dose-level cohort. Phase 2 participants and investigators and study site personnel outside of the surgical team will be masked to the Phase 2 OpCT-001 dose-level assignments.
