EGP-437 demonstrated better clinical performance than vehicle control but did not meet its co-primary endpoints

WALTHAM, MA, USA I February 05, 2018 I EyeGate Pharmaceuticals, Inc. (NASDAQ:EYEG) (“EyeGate” or the “Company”), a clinical-stage, specialty pharmaceutical company with two proprietary platform technologies for treating diseases and disorders of the eye, today announced top-line results from a Phase 2b study of EGP-437 combination product for pain and inflammation in patients having undergone cataract surgery. Although, EGP-437 demonstrated a higher rate of success compared to vehicle at all time points, the co-primary endpoints of proportion of subjects with an anterior chamber cell (ACC) count of zero at day 7 and the proportion of subjects with a pain score of zero at day 1 did not show statistical significance.

“The efficacy results for the absence of inflammatory cells in the EGP-437 treatment group met our expectations, but the vehicle group response was better than anticipated. The magnitude of reduction for EGP-437 compares favorably with the historical data from studies of other anti-inflammatory products, which we believe is an encouraging sign,” said Randall Olson MD, strategic advisor to EyeGate.

The double-masked, randomized, vehicle-controlled Phase 2b study enrolled 106 subjects at seven U.S. clinical sites. The trial evaluated the safety and efficacy of trans-scleral iontophoretically-delivered EGP-437, dexamethasone, through the Company’s EyeGate® II Delivery System in patients that have previously undergone cataract surgery with implantation of a monofocal posterior chamber IOL, starting immediately after surgery.

EGP-437 showed numerically better clinical efficacy, defined as an ACC count of zero, throughout the study, especially at Day 14 and beyond. At a majority of timepoints, a greater number of subjects in the EGP-437 arm achieved a pain score of zero compared to control. For the secondary endpoints, based on change in mean cell count and change in mean pain score, EGP-437 showed statistically significant improvements in both ACC count and pain score, on Day 7 and Day 1 respectively. In addition, the EGP-437 arm demonstrated a favorable safety profile with no serious adverse events reported.

“We will continue to review the data to determine next steps and to continue evaluating EGP-437 for the reduction of pain and inflammation following ocular surgery,” said Barbara Wirostko MD, Chief Medical Officer of EyeGate.

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 most advanced platform is based on a cross-linked thiolated carboxymethyl hyaluronic acid (“CMHA-S”), a modified form of the natural polymer hyaluronic acid (“HA”), which 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.  For more information, please visit www.EyeGatePharma.com.
