RestorGenex Announces Data on the Effect of RES-529 in Pulmonary Fibrosis Models

Scientific Data Presentation of RES-529 at the American Thoracic Society

Los Angeles, California, UNITED STATES

BUFFALO GROVE, Ill., May 21, 2015 (GLOBE NEWSWIRE) -- RestorGenex Corporation (OTCQB:RESX), a specialty biopharmaceutical company focused on developing products for oncology, ophthalmology and dermatology, announced that Keith Ferguson, M.D. and Nathan Sandbo, M.D., both of the Division of Allergy, Pulmonary, and Critical Care Medicine, University of Wisconsin School of Medicine and Public Health, presented scientific data utilizing RES-529 in idiopathic pulmonary fibrosis. The poster entitled "The Novel TOR Complex 1/2 Inhibitor RestorGenex 529 (RES-529) Inhibits Human Lung Myofibroblast Differentiation" was presented on Tuesday, May 19, 2015 at the American Thoracic Society International Conference in Denver, Colorado.

The presentation discussed results from pre-clinical research evaluating RES-529, a small molecule that interferes with the molecular components which make up TORC1 and TORC2 protein complexes within the PI3K/Akt/mTOR pathway. The focus of the presentation was on in vitro and in vivo models of idiopathic pulmonary fibrosis (IPF). IPF is a disabling progressive and often deadly disorder with very few therapeutic options in which the lungs become progressively scarred over time causing shortness of breath, coughing, and limiting participation in everyday physical activities. Current treatments for IPF include oxygen therapy, pulmonary rehabilitation, and lung transplant. Median survival for IPF patients is only two to four years.

The persistent activation of myofibroblasts has been described in IPF and signaling via the PI3K/Akt/mTOR pathway has been shown to mediate myofibroblast differentiation. These studies investigated the potential antifibrotic effect of RES-529 in (1) TGF-β dependent activation of the PI3K/Akt/mTOR pathway, (2) myofibroblast differentiation, and (3) an in vivo pulmonary fibrosis model.

RES-529 was shown to inhibit both mTOR-dependent signaling and myofibroblast differentiation in human lung fibroblasts. In a 10-day in vivo mouse model of bleomycin-induced pulmonary fibrosis, RES-529 showed a trend toward improved survival and less histologic fibrosis.

 "There is a large need for better treatments for patients with idiopathic pulmonary fibrosis. This data support the potential effectiveness of dual inhibition of both TORC1 and TORC2 with RES-529 in halting some of the key cellular events that promote pulmonary fibrosis," said Nathan Sandbo, M.D., senior author of the presentation. 

Stephen M. Simes, chief executive officer of RestorGenex added, "Idiopathic pulmonary fibrosis is a devastating disease. While our current focus is on the use of RES-529 in oncology and ophthalmology, we believe that RES-529 has potentially wide-ranging applications in treating other diseases as demonstrated by this encouraging research of RES-529 as a treatment for pulmonary fibrosis."
