Analytical Bio-Chemistry Laboratories to Develop Liprostin Assays for Endovasc's Phase III Trial


HOUSTON, June 27, 2006 (PRIMEZONE) -- Endovasc, Inc. (OTCBB:EVSC) today announced that the Company has awarded Analytical Bio-Chemistry Laboratories, Inc. a contract to develop an assay to determine the content of Prostaglandin E-1 (PGE-1) in the blood of patients during and post delivery of Liprostin. The pharmakokinetic studies will be carried out in parallel with the Liprostin Phase III studies. Currently there is no validated analytical study on record in the U.S. to determine the concentration of both PGE-1 and its active metabolite at concentrations that Endovasc expects to see in the bloodstream.

"Our Liprostin liposome formulation was designed to slow the release of PGE-1 and thereby maintain a low, biologically active level of the drug in the body for an extended period of time. Normally, an intravenous injection of free PGE-1 is metabolized within 90 seconds as it passes through the lungs. This study will measure the release rate of PGE-1 from the liposome into the bloodstream," said Diane Dottavio, Ph.D., Endovasc's Chairman and Chief Executive Officer.

Endovasc's Liprostin is a liposome-encapsulated form of Prostaglandin E-1 (PGE-1) which is known to be a potent vasodilator and platelet inhibitor as well as an anti-inflammatory and anti-thrombotic agent. Endovasc has submitted its protocol for a phase IIIa clinical trial of Liprostin for the treatment of intermittent claudication, a symptom of Peripheral Arterial Disease, to the FDA. Intermittent claudication causes a cramping sensation in the legs that is present during exercise or walking and occurs as a result of decreased oxygen supply.
