King Pharmaceuticals®, Inc. Initiates Phase II Clinical Trial Evaluating MRE0094 As A Treatment For Diabetic Foot Ulcers

BRISTOL, Tenn., Jan. 5 /PRNewswire-FirstCall/ -- King Pharmaceuticals, Inc. announced today that it has initiated the Company’s Phase II clinical trial program evaluating the safety and efficacy of its topical investigational drug MRE0094 in patients with chronic, neuropathic, diabetic foot ulcers.

“We are very excited about the potential of MRE0094 as a safe and effective treatment for chronic, neuropathic, diabetic foot ulcers. During the course of our Phase I study in patients with this condition, we observed no safety issues related to MRE0094 and noted positive effects on the rate of wound closure,” stated Michael K. Jolly, Pharm.D., Executive Vice President, Research and Development, of King. “MRE0094 is a novel, adenosine A2A receptor agonist that favorably affects the inflammation associated with these ulcers by regulating the response of inflammatory cells and mediators, and by enhancing the tissue proliferation phase of wound healing. By virtue of these various mechanisms including endothelial cell proliferation and migration, MRE0094 promotes tissue remodeling.”

Dr. Jolly noted, “Diabetes is a major U.S. health concern affecting over 6% of the population. The incidence of diabetes is increasing at a rate of approximately 1.3 million new cases diagnosed per year. With the increasing prevalence of diabetes, the neuropathic, diabetic foot ulcer has become a major physical, emotional, and economic burden affecting patients, families, caregivers, and health systems. Approximately 15% of diabetic patients will develop foot ulceration during the course of their disease.” Dr. Jolly added, “Hospital admissions of diabetic patients with neuropathic foot ulcers are often prolonged by infection, gangrene, and lower extremity amputation.”

Chronic, neuropathic, diabetic foot ulcers are a part of the wound healing market which is estimated at greater than $3 billion in the United States. The U.S. Food and Drug Administration has not yet evaluated the safety or efficacy of MRE0094.
