New Case Series Demonstrates Potential of Aquadex Therapy for End-Stage Liver Disease Patients with Fluid Overload

February 6, 2024
Early findings suggest Aquadex as a potential solution to safely and effectively remove fluid volume for liver disease patients who don’t respond to diuretics

MINNEAPOLIS, Feb. 06, 2024 (GLOBE NEWSWIRE) -- Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company focused on transforming the lives of people with fluid overload, today announced the publication of new data demonstrating the potential value of the Aquadex SmartFlow® system’s aquapheresis therapy when treating patients with fluid overload as a result of end-stage liver disease. The publication, “Utilization of Aquapheresis Among Hospitalized Patients with End-Stage Liver Disease: A Case Series and Literature Review,” is a single-center retrospective case series featured in Clinical Transplantation.

“This study presents an exciting new market opportunity for Nuwellis, and we look forward to gathering additional data demonstrating how Aquadex can benefit these patients,” said Nestor Jaramillo, Jr., president and chief executive officer of Nuwellis. “Four and a half million adults in the U.S. have been diagnosed with liver disease.1 To date, there has been little to no clinical evidence gathered demonstrating the benefits of aquapheresis for patients with liver disease. This publication lays the foundation for a new clinical application already within our current labeling that requires no additional regulatory clearances from the FDA.”

The case series assessed the utilization of aquapheresis therapy with Aquadex in the intensive care unit (ICU) setting at Mount Sinai Hospital between January 2020 and July 2023. Fourteen severely ill patients with end-stage liver disease were treated with aquapheresis during this period. The most common cause of liver disease was alcohol-related, with nine of the 14 patients presenting with alcohol-associated cirrhosis. Key findings from the case series include:

  • Six patients were able to receive physical therapy following treatment to help improve their mobility while in the ICU.
  • Five patients were transferred out of the ICU following treatment, three of whom were discharged from the hospital.
  • There were no catheter-related bloodstream infections or circuit complications attributed to aquapheresis access.

“For clinicians treating patients with end-stage liver disease, it can be an enormous challenge to safely and effectively remove fluid when patients don’t respond to or can’t tolerate diuretic therapy,” said John Jefferies, M.D., chief medical officer of Nuwellis. "In such cases, fluid removal via aquapheresis can enhance patients' mobility and allow them to receive more effective physical therapy. This can reduce cirrhosis-related frailty and enhance their ability to receive a life-saving liver transplant in a more timely manner."

Patients with end-stage liver disease are currently treated with diuretics, but studies show that the longer a patient is on diuretics, the less effective they become.2,3 End-stage liver disease patients are also prone to developing ascites, which requires paracentesis – a painful procedure using a needle to remove fluid from the peritoneal cavity. In this case series, Aquadex was shown to provide a potential additional solution to mitigate these clinical gaps.

Aquadex is proven to simply, safely, and precisely remove excess fluid from patients suffering from fluid overload who have not responded to conventional medical management, including diuretics. Providers can specify and adjust the rate of fluid removed for each individual patient, resulting in a gradual reduction of excess fluid. The device’s built-in, customizable hematocrit monitoring technology provides real-time measurement of percent blood volume changes that can be tailored to individual patients’ needs. A customizable fluid removal rate is particularly important for pediatric patients who have a small amount of blood in their bodies. The Aquadex system is cleared by the U.S. Food and Drug Administration (FDA) for use in adults and pediatric patients weighing 20 kg (44 lbs.) or more.
