EyeGate Pharma Receives Positive Guidance From FDA on NDA Filing Requirements of EGP-437 for the Treatment of Anterior Uveitis

Agency Provides Guidance That Positive Data From Upcoming Phase 3 Trial Sufficient to Support NDA Filing
WALTHAM, Mass., May 4, 2015 (GLOBE NEWSWIRE) — Eyegate Pharmaceuticals, Inc. (OTCQB:EYEG) (“EyeGate” or the “Company”), a specialty pharmaceutical company that focuses on developing and commercializing therapeutics and drug delivery systems for treating diseases of the eye, today announced receipt of comments from the U.S. Food & Drug Administration (“FDA”) in response to questions submitted by the Company ahead of a Type B meeting scheduled for May 5, 2015. The FDAprovided guidance that if the planned Phase 3 trial of EGP-437 in anterior uveitis meets non-inferiority criteria, data from this trial along with data from a previously completed Phase 3 trial in anterior uveitis will be sufficient to support a New Drug Application (“NDA”) filing. The FDA also communicated that the design of the planned Phase 3 is acceptable and that the nonclinical work completed to date is sufficient to support a NDA filing. Based on this positive feedback, the Company has elected to cancel the face-to-face portion of the meeting.

The planned trial will be a prospective, multi-center, randomized, double-masked, parallel-arm, positive control non-inferiority study evaluating Iontophoretic Dexamethasone Phosphate Ophthalmic Solution compared to the standard of care, Prednisolone Acetate Ophthalmic Suspension (1%) in patients with non-infectious anterior segment uveitis. The trial is expected to enroll up to 250 subjects at approximately 60 U.S. clinical sites. Non-inferiority will be evaluated based on the proportion of subjects with total anterior chamber cell clearing at Day 14 of EGP-437 treatment versus standard of care.

“The FDA comments are an important milestone in our clinical development plan for EGP-437, and we are pleased that they have determined that the proposed Phase 3 trial design is acceptable. The guidance that data from this planned study, along with our previous Phase 3 study of EGP-437 should be sufficient to support a NDA filing gives us a clear clinical and regulatory path for our lead product candidate,” said Stephen From, President and Chief Executive Officer of EyeGate. “We believe that EGP-437 represents a potential breakthrough in the treatment of ocular diseases and that this trial, if successful, would provide a significant validation of the use of iontophoresis for delivery of drug to the eye. We expect that iontophoretic delivery could be applied to a variety of ocular drugs that have traditionally been administered topically or via injection, and could provide a viable therapeutic alternative to patients in need. We look forward to initiating this trial, and to providing further details as we continue to advance.”
