MedicalResearch.com Interview with: Madhav Swaminathan, MBBS, MD, FASE, FAHA Associate Professor with Tenure Clinical Director, Division of Cardiothoracic Anesthesiology & Critical Care Medicine Department of Anesthesiology Duke University Health System Durham, NC 27710 Medical Research: What is the background for this study? What are the main findings? Dr. Swaminathan: The background is the need for salvage therapies for acute kidney injury (AKI,) which is a common complication in hospitalized patients. It is particularly a problem in the postoperative period after cardiac surgery. Preventive strategies have not worked well for decades. Hence the focus on strategies that target kidney recovery. Mesenchymal stem cells have been shown to be useful in enhancing kidney recovery in pre-clinical trials. We therefore hypothesized that administration of human Mesenchymal stem cells (AC607, Allocure Inc, Burlington, MA) to patients with established post-cardiac surgery AKI would result in a shorter time to kidney recovery. We conducted a phase 2, double blinded, placebo controlled, randomized clinical trial to test our hypothesis. Unfortunately we could not confirm the hypothesis and there were no significant differences in time to kidney recovery among patients that received AC607 versus placebo in 156 randomized cardiac surgery subjects.
