CytRx Announces Scientific Data Showing the Potential of Its Oral Drug, Iroxanadine, for the Treatment of Cardiovascular Disease
LOS ANGELES, Dec. 1 /PRNewswire-FirstCall/ — CytRx Corporation announced that its orally available drug candidate, iroxanadine, was effective in treating cardiovascular disease in an experimental mouse model for atherosclerosis. The experiments demonstrated that iroxanadine significantly reduced plaque formation and arterial thickening in mice, both of which are symptoms that lead to serious cardiovascular disease. According to the National Heart, Lung & Blood Institute, atherosclerosis is a leading cause of illness and death in the U.S. and affects approximately 4.6 million people annually.
The experiments were performed in a strain of mouse (“ApoE”) which is genetically engineered to have deficient cholesterol metabolism, which results in acceleration of the generation of cardiovascular disease. Iroxanadine significantly reduced the progression of cardiovascular disease in these animals. “This strain of mouse rapidly develops the classic hallmarks of atherosclerosis, including the formation of plaque and a thickening of blood vessel walls,” said Louis Ignarro, Ph.D., Nobel Laureate and world acclaimed expert in the field of cardiovascular disease. “Treatment with iroxanadine significantly decreased plaque formation and reduced arterial thickening. This is consistent with its proposed mechanism of action, namely restoring the normal function of the endothelial cells lining the blood vessels,” said Dr. Ignarro.
Iroxanadine is believed to work through the activation of certain “molecular chaperone” proteins that repair normal damage to each cell. “The utility of chaperone proteins in preventing the damage that leads to cardiovascular disease has been appreciated in the scientific literature for some time,” said Jack Barber, Ph.D., Sr. Vice President, Drug Development. “However, until now we were not aware of an easy way to stimulate the right chaperones in the right tissues. These unpublished preclinical results, in conjunction with the human safety data previously generated from a Phase II clinical trial, suggest that iroxanadine may be the right way,” said Dr. Barber.
“We continue to be impressed by the therapeutic potential of the three oral drug candidates we recently acquired from Biorex,” said Steven Kriegsman, President and CEO. “The main motivation for our acquisition was the drug arimoclomol, for which we plan to initiate a phase II clinical trial for ALS (‘Lou Gehrig’s disease’) in the second quarter of 2005 and also continue development for type 2 diabetes. CytRx’s internal drug development efforts will continue to focus on the utility of iroxanadine for other diseases, such as diabetic wound healing and retinopathy, but we are actively seeking to partner with a large pharmaceutical company for the more challenging, but more lucrative, cardiovascular indication,” said Mr. Kriegsman.
CytRx’s recent acquisition of the clinical and pharmaceutical assets and related intellectual property of Biorex Research & Development Company significantly expanded and accelerated the company’s drug development pipeline with the addition of three oral, clinical stage drug candidates, a library of 500 small molecule drug candidates, and an extended patent portfolio. The acquisition positions CytRx as a clinical-stage company and also complements the company’s business by expanding the scope of therapeutic development programs.
