NCT ID NCT04438213

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial at Yale University is testing whether the diabetes drug ertugliflozin can help people with chronic heart failure manage fluid buildup better than a standard diuretic (metolazone) or a placebo. Sixty adults on daily diuretics will take one of the three treatments for six weeks. Researchers will measure changes in blood volume and sodium excretion to see if ertugliflozin offers unique benefits without causing dehydration.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Ertugliflozin (a diabetes drug) and metolazone (a diuretic)

What this could lead to

If successful, this could show that ertugliflozin helps manage heart failure better than standard diuretics, with fewer side effects like dehydration.

What could go wrong

This is a small, early-phase study (60 people) looking at short-term effects. It may not prove long-term benefit or safety, and results may not apply to all heart failure patients.
