Can a diabetes drug shield hearts from chemo damage?
NCT ID NCT06888505
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether dapagliflozin (Farxiga), a drug used for diabetes and heart failure, can prevent heart damage caused by anthracycline chemotherapy. 94 adults with cancer took either dapagliflozin or a placebo daily for four months alongside their chemo. Researchers measured heart function and blood markers to see if the drug offered protection.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dapagliflozin (Farxiga)
- What this could lead to
- If it works, this could point toward a way to protect the heart during chemotherapy, reducing the risk of long-term heart damage.
- What could go wrong
- This is a small, early-phase trial with only 94 participants. The results may not apply to everyone, and the drug may not provide meaningful protection in larger studies.
