RegeneRx Provides Update on Clinical Trials in U.S., Korea and China

ROCKVILLE, Md., Aug. 6, 2015 /PRNewswire/ -- RegeneRx Biopharmaceuticals, Inc. (OTCQB: RGRX) ("the Company" or "RegeneRx"), a clinical-stage drug development company focused on tissue protection, repair and regeneration, today provided an update on the status and timing of the four ophthalmic clinical trials for dry eye syndrome and neurotrophic keratopathy (NK) scheduled to commence in the U.S., Korea, and China this year.  In Korea and China the dry eye trials are being sponsored by RegeneRx's strategic partners in their respective territories.  In the U.S., the dry eye and NK clinical trials are being sponsored by ReGenTree, LLC, a joint venture between RegeneRx and G-treeBNT.  RGN-259/GBT-201 is a sterile, preservative-free ophthalmic eye drop that is being tested in the trials.

Representatives of G-treeBNT and RegeneRx recently met with the U.S. Food and Drug Administration to finalize details of the Phase IIb/III trial in patients with dry eye syndrome, which is being sponsored by ReGenTree, LLC.  Based on the positive outcome of the meeting, ReGenTree is preparing to enroll patients in the U.S. dry eye and NK clinical trials in September 2015. The Phase IIb/III dry eye trial is expected to be completed during the first half of 2016 and the Phase III NK trial is expected to be completed in the second half of 2016, or sooner, depending on the speed of patient accrual for this orphan indication.  Additionally, ReGenTree has successfully completed the manufacturing required for Phase III and RGN-259 will soon be shipped to the contract research organization (CRO) managing the clinical trials in the U.S. 

G-treeBNT recently received permission from the Korean Ministry of Food and Drug Safety (MFDS) to begin its Phase IIb/III clinical trial for dry eye syndrome in Korea.  Given the immediate focus of the two U.S. trials, G‑treeBNT is considering the best timing of the Korean trial.

The fourth clinical trial, a Phase II dry eye trial in China is awaiting clearance to start enrollment by the Chinese Food and Drug Administration (CFDA).  RegeneRx intends to provide further updates on all trials as appropriate.
