RegeneRx JV Locks Clinical Trial Database for Phase 3 Dry Eye Trial

ROCKVILLE, Md., Feb. 24, 2021 /PRNewswire/ -- RegeneRx Biopharmaceuticals, Inc. (OTCQB: RGRX) ("the Company" or "RegeneRx"), a clinical-stage biopharmaceutical company focused on tissue protection, repair and regeneration, announced that the ARISE-3 Phase 3 clinical trial database evaluating RGN-259 eyedrops for the treatment of dry eye syndrome has been locked after collecting and verifying patient data from 20 U.S. clinical sites participating in the study.  Database lock is a specific time point prior to unmasking the trial and after which no patient information may be modified.

ReGenTree LLC, the U.S. joint venture company owned by RegeneRx Biopharmaceuticals, Inc. and GtreeBNT, a Korean biopharmaceutical company, is sponsoring the clinical trial and will unmask the study and begin the biostatistical analysis that will include not only primary endpoints, but also other pre-specified endpoints identified in the clinical protocol. 

GtreeBNT has previously stated that it has secured major intellectual property rights, including patents related to composition, formulation, and manufacturing process for RGN-259 eye drops.  Last year RGN-259, a 43 amino acid peptide, was reclassified from a new chemical entity to a biologic by the FDA.  Thus, it will require a Biologics License Application (BLA), rather than a New Drug Application (NDA) for marketing approval and receive 12 years of market exclusivity in the U.S. if the product is approved by the FDA.

GlobalData, a well-known market research publisher worldwide, estimated that the dry eye market will reach $11.1 billion in 2028 in 9 major countries including the U.S. according to its market research report published in May 2020. Also, GlobalData expects that due to RGN-259's unique mechanism of action (MOA), it would garner significant market share during the forecast period after its market launch.

"We are pleased that the ARISE-3 database is locked and undergoing statistical analysis.  Topline results will be released soon and, hopefully, we will see a positive outcome in this very important clinical trial," stated J.J. Finkelstein, RegeneRx president and chief executive.
