Could a diabetes drug help heart failure patients after valve surgery?

NCT ID NCT05672836

First seen Jun 27, 2026 · Last updated Jun 30, 2026 · Updated 2 times

Summary

This study tests whether a drug called enavogliflozin can prevent major heart problems or worsening heart failure in people who have had a heart valve replacement (TAVR) and still have heart failure. About 1,040 participants will receive either the drug or a placebo, in addition to standard care. The main goal is to see if the drug reduces the chance of death, heart attack, stroke, or hospitalization for heart failure over one year.

What this could mean

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

Active substance
Enavogliflozin (a drug that helps the kidneys remove sugar from the blood, also used for diabetes)
What this could lead to
If it works, this could provide a new treatment option to reduce heart failure hospitalizations and major heart problems in patients who have had a valve replacement.
What could go wrong
This is a phase 4 trial, so the drug is already approved for diabetes, but its benefit in this specific heart condition is unproven. The trial may show no advantage over placebo, and side effects like dehydration or infections are possible.
