Empagliflozin in Heart Failure: Diuretic and Cardio-Renal Effects (EMPA)

June 24, 2020 updated by: Yale University
The investigators propose a small pilot proof of concept study to not only prove the existence of, but also probe the mechanisms underlying cardio-renal effects of empagliflozin in patients with heart failure. The investigators propose a 50 patient randomized, double-blind, placebo-controlled crossover study with patients with stable HF, type II diabetes and an eGFR >45ml/min/1.73 m2 who are chronically receiving loop diuretics.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study Objectives

  1. Study the acute/short term effect and cardio-renal mechanisms of sodium-glucose cotransporter 2 (SGLT2) inhibition in patients with heart failure.
  2. Determine the effect of chronic combined SLLGT2 and loop diuretic exposure in patients with heart failure.

Primary Outcomes

  1. Aim 1 (Acute): Determine if acute SGLT2 inhibition will improve the natriuretic effect of a loop diuretic compared to placebo.
  2. Aim 2 (Chronic): Determine the effect of 14 days of SGLT2 inhibition on blood volume.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Placebo, then empagliflozin
Patients are randomized upon enrollment to determine whether they take empagliflozin or the matched placebo during the first 2-week treatment phase of the study. All patients then undergo a 2-week "washout period" before crossing over to the alternate therapy.

10mg empagliflozin for a 2-week period
Drug: Placebo Oral Capsule
10 mg placebo for a 2-week period
EXPERIMENTAL: Empagliflozin, then Placebo
Patients are randomized upon enrollment to determine whether they take empagliflozin or the matched placebo during the first 2-week treatment phase of the study. All patients then undergo a 2-week "washout period" before crossing over to the alternate therapy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
urine sodium concentrations via ion selective electrodes
Time Frame: 36 days

Determine if acute SGLT2 inhibition will improve the natriuretic effect of a loop diuretic compared to placebo.

Measuring the natriuretic effect of a loop diuretic (placebo v acute SGLT2 inhibition) via urine sodium output.
36 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
blood volume
Time Frame: 14 days

Determine the effect of 14 days of SGLT2 inhibition on blood volume.

Daxor Blood Volume Sample Collection

  1. Volumex Injection: The Volumex tracer (radiolabeled albumin) is injected as an intravenous bolus (IV-push). (As soon as the tracer injection begins, a stopwatch is started and never zeroed out. Running times are used for the entire procedure).
  2. Serial Blood Collection A series of 5 post-Volumex blood samples is collected, after tracer injection, allowing for complete mixing in the bloodstream.
  3. Sample Timing: Samples are ideally spaced ~6 minutes apart, and are collected approximately 12, 18, 24, 30 and 36 minutes after Volumex administration.
