Rockwell's lead, late-stage investigational drug for iron therapy treatment is called SFP. SFP delivers iron in a non-invasive, physiologic manner to dialysis patients via dialysate during their regular dialysis treatment. SFP is currently in ongoing Phase III clinical trials (CRUISE-1 and CRUISE-2) and addresses a $600M U.S. and $1B global market. Rockwell's Calcitriol (Active Vitamin D) injection for treating secondary hyperparathyroidism addresses a $350M U.S. market.

Rockwell is also an established manufacturer and leader in delivering high-quality hemodialysis concentrates/dialysates to dialysis providers and distributors in the U.S. and abroad. These products are used to maintain human life by removing toxins and replacing critical nutrients in the dialysis patient's bloodstream. Rockwell's operating business is designed as a ready-made sales and distribution channel to provide seamless integration into the commercial market for its drug products, Calcitriol and SFP upon FDA market approval.

Rockwell's exclusive renal drug therapies support disease management initiatives to improve the quality of life and care of dialysis patients and are intended to deliver safe and effective therapy, while decreasing drug administration costs and improving patient convenience. Rockwell Medical is developing a pipeline of drug therapies, including extensions of SFP for indications outside of hemodialysis. Please visit [ www.rockwellmed.com ] for more information.
