Gator SCALES-WHF: SubCutaneous Administration of Lasix to Eliminate Symptoms of Worsening Heart Failure

Recruiting now · Phase 4

Conditions studied: Heart Failure, Volume Overload

In brief

The primary objective of the study is to develop, implement, and evaluate a site-specific clinical pathway for at-home treatment of eligible patients presenting to the clinic with worsening heart failure. The secondary objectives are: 1. To evaluate patient factors related to parenteral decongestion at home. 2. To evaluate the safety and device operation of Lasix ONYU treatment under circumstances that mimic real-world use. 3. To identify opportunities for process improvement before the routine implementation of the new clinical pathway.
