Ertugliflozin in Chronic Heart Failure: Cardio-renal and Diuretic Effects

Description

The purpose of this study is to determine the effects on heart failure signs and symptoms of the use of either ertugliflozin, metolazone or placebo, in conjunction with intravenous loop diuretic use in acute settings and chronic oral loop diuretic therapy. There are two general purposes for this study. The proposed study is both larger and more rigorous than essentially all PK/PD studies that form the basis of current practice with loop diuretics as well as all studies looking at add-on thiazide therapy (current guideline-recommended adjuvant). The second is to generate a mechanistic understanding of the pleotropic cardio-renal factors with chronic therapy that differentiate ertugliflozin from traditional diuretics particularly in how they maintain reduced blood volume without the complication of over-diuresis and volume depletion.This is a randomized placebo controlled mechanistic study to understand the utility of ertugliflozin in acute and post-acute hospitalized heart failure pati

Trial Eligibility

Inclusion Criteria: 1. A clinical diagnosis of ADHF with at least one objective sign of volume overload (rales, edema, elevated JVP, or preadmission weight gain) 2. As judged by the treating physician, a projected need and ability to tolerate treatment with an extended need for IV diuretics with the goal of significant fluid removal (i.e., goal \>1L/day net fluid loss) 3. Chronic daily oral loop diuretic dose \> or equal to 20mg furosemide equivalents for at least one month prior to admission 4. eGFR 30 mL/min/1.73 m2 5. Signed informed consent Exclusion Criteria: 1. Current use or plan to initiate renal replacement therapy or ultrafiltration this hospital admission 2. Significant bladder dysfunction or urinary incontinence 3. Inability to comply with the serial urine collection procedures 4. Current use of a thiazide or thiazide like diuretics or use within 5 half-lives of the drug, including metolazone 5.
