Rockwell Medical Technologies, Inc. Receives Patent Grant for Proprietary SFP Iron-Delivery in Mexico

Tuesday, October 23, 2007

Wixom, MI -- Rockwell Medical Technologies, Inc. (Nasdaq:RMTI), a leading, innovative manufacturer and developer of renal drug therapies and essential dialysate products, focused on the end-stage-renal-disease (ESRD) market, reported that a Mexican patent was granted for its proprietary drug, Soluble Ferric Pyrophosphate (SFP). The Mexican SFP patent grant covers the method and pharmaceutical composition for iron delivery administered in hemodialysis and peritoneal dialysis patients.

Mr. Robert L. Chioini, Chairman, CEO and President of Rockwell, stated, "We are pleased to add Mexico, estimated to be the 8th largest ESRD market in the world, to further strengthen and protect our proprietary intellectual property for SFP worldwide. In conjunction with the successful completion of our SFP clinical development program, we look to expand into the worldwide markets through the development of our own distribution channels and/or with an established international marketing partner."

About Soluble Ferric Pyrophosphate (SFP) -- Rockwell's Lead Renal Drug Therapy

SFP is a water soluble form of iron designed to provide physiological-iron-maintenance-therapy for anemic ESRD patients. SFP (iron) is uniquely delivered via dialysate directly to the bloodstream, during each kidney dialysis treatment. SFP is a highly stable, non-polymeric iron salt that is administered directly into the bloodstream, avoiding liver toxicity build-up thus overcoming the need for iron release from reticuloendothelial stores in the liver and other organs. The ferric iron core is tightly chelated to a pyrophosphate shell which facilitates transfer of iron from transferrin to ferritin, bypassing the liver entirely.

Based on previous FDA Phase II clinical study results and compared to intravenous (IV) iron administration, SFP delivered via dialysate, has shown to be a safe and effective method for maintaining optimal iron balance in dialysis patients while at the same time decreasing associated nursing and pharmaceutical IV iron administration costs. Furthermore, recent academic studies have shown that more frequent maintenance doses of iron improve the therapeutic response and benefits of recombinant erythropoietin treatments.

Rockwell has licensed the exclusive world-wide rights to SFP and is collaborating with the FDA in its development. Rockwell has secured patents for SFP in multiple countries, including the United States, Japan, and the European Union, covering the largest commercial markets for iron supplementation in the world. Rockwell has issued and pending patents in a number of other markets as well. Rockwell estimates that the U.S. dialysis market for IV-iron delivery is approximately $450 million annually while global market potential is approximately $750 million.
