Monday August 29, 2011

LAWRENCE, Mass., Aug. 29, 2011 /PRNewswire via COMTEX/ —

NxStage® Medical, Inc. (Nasdaq: NXTM), a leading manufacturer of innovative dialysis products, today announced that former NxStage® System One&#153 patient Tederra Coleman is celebrating the one-year anniversary of her successful kidney transplant. Coleman, 33, of Pompano Beach, Florida, received her transplant after experiencing two years of daily home hemodialysis with the NxStage System One&#153. Prior to beginning daily home hemodialysis, Coleman spent seven years undergoing thrice-weekly treatments at a dialysis center.

More frequent dialysis with the System One resulted in such a positive change in Coleman‘s health and quality of life, that she became a certified hemodialysis technician. Her goal is to inform patients about their therapy options, including home hemodialysis with the System One so they can experience the benefits possible with this life changing therapy.

As an in-center dialysis patient, I didn’t like going to the center and the strict schedule was difficult to keep with my job, so I often skipped my treatments, putting my health in jeopardy, said Coleman. It was my desire to dialyze at home that motivated me to become a compliant patient. Once I began using the System One, I finally felt in control of my life and health and managed my dialysis care properly, which allowed me to become a transplant candidate.

Recent objective clinical data from large, well designed trials have proven that more frequent hemodialysis with the System One has a positive impact on patient survival, clinical outcomes and quality of life, stated Jeffrey H. Burbank, Chief Executive Officer of NxStage Medical. We’re pleased to celebrate with Tederra and other patients for whom more frequent hemodialysis with the System One not only allows them to live better, healthier lives, but also may better position them for transplant success.

The Tederra Coleman Story

Tederra Coleman was diagnosed with end stage renal disease (ESRD) at the age of 24 upon a visit to her doctor for a regular checkup. Tederra’s demanding in-center dialysis schedule eventually forced her to quit her job as a customer service representative.

Coleman learned of NxStage’s portable home hemodialysis machine, the System One, in 2008. After completing training with her daughter and trained partner, Ternisha, Coleman began dialyzing at her home five times a week for two hours at a time. The pair typically conducted Tederra’s treatments after Ternisha finished her homework. During her time on the System One therapy, Tederra noticed a marked improvement in her energy levels and mental wellbeing.

Tederra had been placed on the kidney transplant list after beginning therapy with the System One. Two years later, in August of 2010, Tederra received a successful kidney transplant.

Today, Tederra is a certified hemodialysis technician. Inspired and intrigued with her mother’s therapy, Tederra’s daughter, Ternisha, wishes to pursue a career in healthcare and will begin classes this fall at Florida State University College of Medicine.

About the NxStage System One

The NxStage System One is the first and only truly portable hemodialysis system cleared for home use by the U.S. Food & Drug Administration (FDA). Its simplicity and revolutionary size (just over a foot tall) are intended to allow convenient use in patients’ homes and give patients the freedom to travel with their therapy. When combined with the NxStage Pureflow SL Dialysis Preparation System, patients are able to further simplify, using ordinary tap water to create dialysis fluid on demand. Unlike conventional hemodialysis systems, the System One requires no special infrastructure to operate. Under the guidance of their physician, patients can use the NxStage System One, with their trained partners, where, how and when it best meets their needs, at home or on vacation.
