EyeGate Achieves 75% Enrollment in Pivotal Phase 3 Clinical Trial for Anterior Uveitis Triggering Milestone Payment

On track to report topline data in 2Q18 and file NDA within 2018

WALTHAM, Mass., Dec. 18, 2017 — EyeGate Pharmaceuticals, Inc. (NASDAQ:EYEG) (“EyeGate” or the “Company”), a clinical-stage, specialty pharmaceutical company with two platform technologies for treating diseases and disorders of the eye, reported that the Phase 3 pivotal trial of EGP-437 for treatment of non-infectious anterior uveitis has reached 75% patient enrollment. Topline data is expected to be released in the second quarter of 2018.

“This is a critical step toward EyeGate’s goal of commercializing an alternative treatment option for anterior uveitis, a condition characterized by inflammation of the anterior chamber of the eye,” commented Barbara Wirostko, M.D., Chief Medical Officer of EyeGate. “We have made tremendous progress with this study and believe we remain on-track to report topline data from this trial in the second quarter of 2018, with an expected NDA filing for EGP-437 in anterior uveitis next year.”

The Phase 3 trial is a double-masked, randomized, positive-controlled trial enrolling 250 subjects in the U.S. It is designed to assess the safety and efficacy of iontophoretically-delivered EGP-437, a novel formulation of dexamethasone phosphate ophthalmic solution, through the company’s unique EyeGate® II Delivery System, in patients with non-infectious anterior segment uveitis. The value of the EyeGate® II Delivery System, is the ability to potentially eliminate the need for frequently administered topical steroids over multiple weeks. The primary efficacy endpoint is the proportion of subjects with an anterior chamber (AC) cell count of zero at day 14.

By achieving 75% enrollment in the study, EyeGate has earned a milestone payment under its licensing agreement with a subsidiary of Valeant Pharmaceuticals International (NYSE:VRX and TSX:VRX). In 2015, Eyegate and Valeant entered into an exclusive, worldwide licensing agreement, through which EyeGate granted Valeant exclusive, worldwide commercial and manufacturing rights to its EyeGate® II Delivery System and EGP-437 combination product in the field of uveitis, as well as a right of last negotiation to license such product for other indications. Valeant also has exclusive, worldwide rights to commercial and manufacture this combination product for the treatment of post-operative ocular inflammation and pain in ocular surgery patients, pursuant to a license agreement executed in February 2017.

About EyeGate

EyeGate is a clinical-stage specialty pharmaceutical company focused on developing and commercializing products using its two proprietary platform technologies for treating diseases and disorders of the eye.

EyeGate’s CMHA-S platform is based on cross-linking thiolated carboxymethyl hyaluronic acid, a modified form of the natural polymer hyaluronic acid (“HA”). This is a gel that possesses unique physical and chemical properties such as hydrating and healing when applied to the ocular surface. The ability of CMHA-S to adhere longer to the ocular surface, resist degradation and protect the ocular surface makes it well-suited for treating various ocular surface injuries.

EGP-437, EyeGate’s other product in clinical trials, incorporates a reformulated topically active corticosteroid, Dexamethasone Phosphate, that is delivered into the ocular tissues through EyeGate’s proprietary innovative drug delivery system, the EyeGate II Delivery System. www.EyeGatePharma.com.
