100 Patient Pilot Randomized Control Trial

Fluid management of Acute decompensated heart failure Subjects Treated with Reprieve System

The FASTR pilot trial was a multicenter, randomized, controlled trial designed to evaluate the efficacy and safety of the Reprieve Therapy in optimizing decongestion in ADHF patients. The trial enrolled a total of 100 patients, 96 of whom were randomized 1:1 to receive treatment with the Reprieve Therapy or optimal diuretic treatment based on best-practice dosing.

Pivotal Trial -- NOW ENROLLING

Overview

Overview

FASTR II (Fluid Management of ADHF Subjects Treated with Reprieve) is a randomized, controlled pivotal trial in the United States and Europe.
The study will compare outcomes between patients receiving guided decongestive therapy with the Reprieve System and those receiving optimal standard care (conventional diuretic therapy).
Key endpoints include the amount of fluid and sodium removed within 24 hours, kidney function measures, and patient outcomes such as length of stay and readmissions.
