Rockwell Medical Announces SFP Phase 3 Efficacy Study CRUISE-1 Completes Patient Dosing

WIXOM, MI--(Marketwired - May 29, 2013) - Rockwell Medical (NASDAQ: RMTI), a fully-integrated biopharmaceutical company targeting end-stage renal disease (ESRD) and chronic kidney disease (CKD) with innovative products and services for the treatment of iron deficiency, secondary hyperparathyroidism and hemodialysis, announced today that its CRUISE-1 Phase 3 efficacy study for SFP has completed patient dosing. SFP is the Company's late-stage investigational iron-delivery drug for the treatment of iron deficiency in chronic kidney disease patients receiving hemodialysis. CRUISE-1 top-line data is expected in July 2013.

"Completing the CRUISE-1 efficacy study is a major milestone achievement for Rockwell, and we are excited to be so close to top-line results," stated Robert L. Chioini, Founder, Chairman and CEO of Rockwell Medical. "Our clinical team continues to perform at a high level, and we thank them, the study investigators and certainly the patients for their outstanding effort and participation. We look forward to the upcoming CRUISE-1 study results."

"We are very pleased to complete this important study," stated Dr. Raymond Pratt, Chief Medical Officer of Rockwell Medical. "SFP is a very promising iron drug that will address the unmet need for correcting functional iron deficiency in CKD-HD patients. The results of the placebo controlled PRIME study, recently reported at the ERA-EDTA Congress in Istanbul, demonstrated that SFP reduced the ESA dose required to maintain hemoglobin by a statistically significant 35% compared to placebo. The CRUISE studies do not allow changes in ESA dosing, so we are confident that in the CRUISE study design, SFP will show a favorable difference in hemoglobin levels compared to placebo."

The CRUISE Studies
Rockwell is conducting two pivotal Phase 3 efficacy studies called CRUISE-1 and CRUISE-2. Each study is a prospective, randomized, placebo-controlled, multicenter study to demonstrate efficacy and safety of SFP-iron, delivered via dialysate, in adult CKD patients requiring hemodialysis. Each study comprises approximately 300 patients, randomized equally between SFP and placebo groups with a treatment period of up to 12 months. The primary efficacy end-point for both studies is the mean change in hemoglobin from baseline.

About SFP
SFP is a unique iron compound that is delivered to the hemodialysis patient via dialysate, replacing the 5-7 mg of iron lost during a dialysis treatment. SFP is introduced into the sodium bicarbonate concentrate that subsequently is mixed into dialysate. Once in the dialysate, SFP crosses the dialyzer membrane and enters the bloodstream where it immediately binds to apo-transferrin and is taken to the bone marrow, mimicking the way dietary iron is processed in the human body. In completed clinical trials to date, SFP has demonstrated that it can safely deliver iron and maintain hemoglobin levels while decreasing ESA use, without an increase in iron stores.

About Rockwell Medical
Rockwell Medical is a fully-integrated biopharmaceutical company targeting end-stage renal disease (ESRD) and chronic kidney disease (CKD) with innovative products and services for the treatment of iron deficiency, secondary hyperparathyroidism and hemodialysis.

Rockwell's lead drug candidate in late-stage clinical development is for the treatment of iron deficiency in dialysis patients and is called Soluble Ferric Pyrophosphate (SFP). SFP delivers iron to the bone marrow of dialysis patients in a non-invasive, physiologic manner via dialysate during their regular dialysis treatment. In completed clinical trials to date, SFP has demonstrated that it can safely deliver sufficient iron to the bone marrow. SFP is nearing completion of its Phase 3 clinical studies (CRUISE-1 and CRUISE-2) and is expected to address an estimated $600M U.S. market.

Rockwell is preparing to launch its FDA approved generic drug called Calcitriol to treat secondary hyperparathyroidism in dialysis patients. Calcitriol active vitamin D injection is indicated in the management of hypocalcemia in patients undergoing chronic renal dialysis. It has been shown to significantly reduce elevated parathyroid hormone levels. Reduction of PTH has been shown to result in an improvement in renal osteodystrophy. Rockwell intends to launch Calcitriol as soon as it receives FDA manufacturing approval, addressing an estimated $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. As one of the two major suppliers in the U.S., Rockwell's products are used to maintain human life by removing toxins and replacing critical nutrients in the dialysis patient's bloodstream. Rockwell has three manufacturing and distribution facilities located in the U.S. and its operating infrastructure is a ready-made sales and distribution channel that is able 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.
