CVS Health Starts Clinical Trials for Home Dialysis System

CVS Health shares were unchanged in the premarket after the company said it would start a clinical trial of an experimental home-dialysis system for patients with end-stage renal disease. End-stage renal disease requires patients who haven't had kidney transplants to use dialysis machines to clear their blood of waste and excess fluid. The company estimates that more than 37 million Americans have kidney disease, with nearly 700,000 having end-stage renal disease.
