Safety and Efficacy Study of EGP-437 (Dexamethasone Phosphate Formulated for Ocular Iontophoresis) to Treat Dry Eye

Dry eye is the most prevalent form of ocular discomfort and irritation. Estimates range from 20 million people in the United States being affected with mild to moderate dry eye, to as many as one out of every five Americans.

EyeGate completed a single-center, randomized, double-masked, placebo-controlled Phase 2 efficacy study in 105 subjects with mild to moderate dry eye disease, utilizing the Controlled Adverse Environment (CAE), a clinical model which allows for standardized measurement of dry eye signs and symptoms in the investigation of therapeutic agents. In this Phase 2 study, the improvements documented in dry eye signs and symptoms relative to the placebo group indicated that the ocular iontophoresis treatments with EGP-437 (dexamethasone phosphate formulated for ocular iontophoresis) had both a rapid onset of action and a long-term effectiveness.

The Phase 3 study is intended to confirm and extend the results from the Phase 2 study, utilizing the CAE model. The study is designed to assess the safety and efficacy of EGP-437 at two different dose levels: Ocular Iontophoresis with EGP-437 4.0 mA-min at 1.5 mA and Ocular Iontophoresis with EGP-437 6.5 mA-min at 2.5 mA compared to Ocular Iontophoresis with placebo (sodium citrate buffer solution) for the treatment of the signs and symptoms of dry eye.
