Polydiuretic Therapy for Heart Failure With Preserved Ejection Fraction and Diabetes Mellitus

Phase 4

Withdrawn

• Conditions: HF - Heart Failure; Diabetes Mellitus
• Interventions: Drug: Bumetanide 0.5 mg, dapaglifozin 5 mg, eplerenone 25 mg

• Registration Number: NCT04697485
• Lead Sponsor: Northwestern University

Brief Summary

This is a single-center, non-randomzied pilot study investigating a combination of targeted therapies as possible treatment for heart failure with preserved ejection fraction (HFpEF).

The study interviention is a Low-Dose, Triple Polydiuretic Therapy (LDTPT, or polydiuretic) including loop diuretic (bumetanide), mineralocorticoid receptor antagonist (eplerenone), and Sodium-glucose co-transporter 2 inhibitors (SGLT2i) therapy (dapaglifozin).

Detailed Description

Patients with HFpEF and diabetes mellitus will receive polydiuretic therapy consisting of bumetanide 0.5 mg + eplerenone 25 mg + dapaglifozin 5 mg on top of background therapy. These medicines are currently FDA approved and recommended by clinical practice guidelines for the treatment of HFpEF (bumetanide, eplerenone) and diabetes mellitus (dapaglifozin).

This study is designed to evaluate if combination pharmacotherapies with synergistic or additive diuretic properties can improve adherence, treatment efficacy, and effectiveness with fewer side effects
