Phase 1 Open-Label, Dose-Escalation Study of the Safety, Tolerability and Preliminary Efficacy of Intravitreal 4D-110 in Patients With Choroideremia

4D-110-CP-0001

This study will evaluate safety, tolerability, and preliminary efficacy of a single intravitreal (IVT) injection of a recombinant adeno-associated virus (AAV) gene therapy, 4D-110, in male patients with genetically-confirmed Choroideremia (CHM).

Key Inclusion Criteria: * Diagnosis of CHM defined as a pathogenic mutation in the CHM gene, confirmed by genetic testing * Both eyes must have ≥ 34 ETDRS letters (\~20/200) Key Exclusion Criteria: * Clinically significant, active ocular or peri-ocular infection or inflammation in the study eye * Patient has previously received any AAV treatment * Ocular conditions or ocular media opacity in either eye that would preclude the planned treatment (i.e. IVT injection) or interfere with the interpretation of study endpoints (e.g. significant lens opacity)
