Summary

This phase 2 trial tests whether dapagliflozin, a drug used for diabetes, can prevent heart damage caused by the chemotherapy drug doxorubicin in breast cancer patients. Researchers will enroll 46 women with early-stage breast cancer who are about to start chemotherapy. Participants will take dapagliflozin daily during their treatment cycles, and doctors will monitor heart function using echocardiograms and blood tests to see if the drug helps maintain a healthy heart.

What this could mean

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

Active substance
dapagliflozin (a diabetes drug repurposed to protect the heart)
What this could lead to
If it works, this could offer a simple way to protect breast cancer patients' hearts during chemotherapy, reducing the risk of long-term heart problems.
What could go wrong
This is a small, early-phase trial with only 46 participants, so results may not apply to everyone. Dapagliflozin may not prevent heart damage, and side effects like dehydration or infection are possible.
