Safety and Efficacy Study of GEB-101 Injection in Subjects With TGFBI-related Corneal Dystrophy

This is a Phase 1/2 seamless, adaptive, multi-center, sequential study evaluates the safety and efficacy of GEB-101 in adult participants with TGFBI-related corneal dystrophy. The Phase 1 part is a single-arm, open-label, dose-escalation study with three planned cohorts , followed by 2 expansion cohorts at the recommended Phase 2 dose. The Phase 2 transitions to a randomized, double-blind, vehicle-controlled, self-controlled design. After completing the primary 1-year follow-up, a long-term follow-up will be proposed to all the participants who received GEB-101 treatment, with close in site follow-up conducted from Year 2 to Year 5, followed by telephone or questionnaire-based follow-up until Year 15.
