Multi-Center, Retrospective Study Evaluates Use of Ultrafiltration Therapy with Aquadex FlexFlow® System in Pediatric Patients

September 24, 2019

EDEN PRAIRIE, Minn., Sept. 24, 2019 (GLOBE NEWSWIRE) -- CHF Solutions, Inc. (Nasdaq:CHFS) today announced the publication of a multi-center, retrospective study in the Clinical Journal of the American Society of Nephrology¹ evaluating the use of hemofiltration and ultrafiltration therapy with the company’s Aquadex FlexFlow system in pediatric patients. The Aquadex FlexFlow system is not yet cleared by FDA for use in pediatric patients.

The study, titled “Kidney Support in Children Using an Ultrafiltration Device,” included 117 patients in three weight categories: <10 kgs; 10-20 kgs; and >20 kgs, suffering from volume overload, acute kidney injury or end-stage kidney disease. All patients across the three weight categories were treated with the Aquadex FlexFlow system, using one of the following three modalities: slow continuous ultrafiltration (SCUF); continuous veno-venous hemofiltration (CVVH); or prolonged intermittent kidney replacement therapy, based on patient condition.

The primary outcome was survival to the end of therapy. In patients weighing over 20 kgs (n=32), 97% survived to the end of therapy. In patients weighing between 10-20 kgs (n=13), 100% survived to the end of therapy. In patients weighing under 10 kgs (n=72), 60% survived to the end of therapy.

“We report the first multi-center experience in pediatrics in which we use an ultrafiltration device to provide kidney support therapy in younger patients," said David Askenazi, M.D., M.S.P.H., Professor of Pediatrics at the University of Alabama Birmingham/Children’s of Alabama. “For many of the types of patients in the study, available therapies require very high relative extracorporeal blood volumes, which can be challenging. With the use of an ultrafiltration device with a small blood volume, we were able to initiate therapy with excellent hemodynamic stability.”

As previously announced, the company will be hosting a conference call and webcast with investigators from the study tomorrow, September 25, at 1:00 pm Eastern Time.
