RegeneRx JV Announces Results of ARISE-2 Dry Eye Trial

ROCKVILLE, Md., Oct. 31, 2017 /PRNewswire/ -- RegeneRx Biopharmaceuticals, Inc. (OTCQB: RGRX) ("the Company" or "RegeneRx"), a clinical-stage drug development company focused on tissue protection, repair and regeneration, today announced the results of its phase 3 dry eye trial sponsored by its U.S. joint venture, ReGenTree, LLC.  The ARISE-2 trial investigated the safety and efficacy of RGN-259 compared to placebo for the treatment of the signs and symptoms of dry eye syndrome in 601 patients. 

The following two paragraphs are excerpted from the ReGenTree press announcement:

"The ARISE-2 study, which was conducted together with Ora, Inc., demonstrated a number of statistically significant improvements in both signs and symptoms of dry eye syndrome with 0.1% RGN-259 versus placebo, while showing excellent safety, comfort, and tolerability profiles. The ocular discomfort symptom showed a statistically significant reduction in the RGN-259-treated group at day 15 as compared to placebo (p=0.0149) in the change from baseline. For sign, RGN-259 also improved the dry eye patient's ability to withstand an exacerbated condition in a patient subgroup with both compromised corneal fluorescein staining and Schirmer's test at baseline. In this population, RGN-259 showed superiority over placebo in reducing corneal fluorescein staining in the change from baseline at days 15 and 29 (p=0.0207 and 0.0254, respectively). RGN-259 confirmed its global effects on dry eye syndrome and fast onset in multiple sign and symptom efficacies with no safety issues in the ARISE-1 and ARISE-2 studies as well as in the pooled data, although ARISE-2 was not successful in duplicating the results of ARISE-1 where the study population was limited and less diversified."

"Won S. Yang, President & CEO of ReGenTree, stated, 'We are very excited with the ARISE-2 results, which show RGN-259's important additional efficacies lacking in approved treatments, such as very fast onset and multiple global effects in both signs and symptoms of dry eye syndrome. I believe these two studies, ARISE-1 and ARISE-2 with efficacy of Tβ4 in both signs and symptoms, will continue building a strong foundation of its strengths when considered with the totality of the data set. ReGenTree plans to proceed with a development plan for the next step through a meeting with the FDA based on the results of ARISE-2 trial. We are optimistic that the results from ARISE-2 will accelerate discussions with potential investors interested in reaching a global deal for the development and marketing of RGN-259.'"
