Subcutaneous Furosemide in Acute Decompensated Heart Failure Pilot

• Status: Completed
• Trial end date: 2017-11-07
• Target enrollment: 0
• Participant gender: All

Summary

The Pilot study is designed to evaluate the overall safety and feasibility of a strategy based on subcutaneous delivery of furosemide. It will be used to inform the subsequent evaluation phase of the study (separate protocol). The primary objective of the study is to determine if a strategy of a novel subcutaneous delivery of furosemide is safe and feasible in patients with acute heart failure.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Adrian Hernandez
• Treatments: Furosemide
