Abstract
OBJECTIVE: To evaluate the efficacy and safety of a single-dose intravitreal umedaptanib pegol (anti-FGF2, investigational new drug) for the treatment of neovascular age-related macular degeneration (nAMD). METHODS: Nine participants who had a diagnosis of refractory nAMD were enrolled and received a single intravitreal injection of umedaptanib pegol at increasing doses of 0.2, 1.0 or 2.0 mg in the study eye. RESULTS: All three doses of umedaptanib pegol evaluated in the study were safe and well tolerated. No severe adverse event (AE) was observed in the study. There was an improvement in retinal fluid measured by central subfield thickness (CST) in most subjects. Remarkably, all three subjects who received 2.0 mg/eye showed improvement of more than 150 μm. CONCLUSIONS: Intravitreal umedaptanib pegol was safe, well tolerated, and demonstrated an indication of bioactivity in participants that have persistent subretinal fluid refractory to the treatment with anti-VEGFs.
