Official title

A Phase 1, Multicenter, Open-label, Single-dose, Dose-escalation Study in Patients With Geographic Atrophy (GA) Secondary to Dry Age-related Macular Degeneration (AMD) to Evaluate the Safety, Tolerability, Pharmacodynamics, and Immunogenicity of Intravitreal Injections of GEM103

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study is designed to identify the maximum tolerated dose (MTD) for intravitreal (IVT) administration of GEM103 in subjects with geographic atrophy (GA) secondary to dry AMD. Safety and tolerability of a single dose of GEM103 will be assessed based on the occurrence of dose-limiting toxicities (DLTs). Each subject will be followed for safety, pharmacokinetic (PK), clinical, and biomarker evaluations. Three escalating dose cohorts are planned.
