What this trial studies

This study investigates whether dapagliflozin can mitigate cardiotoxicity caused by anthracycline-based chemotherapy in women with stage I-III breast cancer. Participants who are chemotherapy-naive and scheduled to receive treatment will be enrolled and randomly assigned to receive either dapagliflozin or standard care. The study aims to assess the efficacy of dapagliflozin in preserving heart function during chemotherapy. By focusing on patients receiving targeted therapies like trastuzumab, the study seeks to address a significant complication associated with effective cancer treatments.

Who should consider this trial

Good fit: Ideal candidates are adult women aged 18 to 70 who are chemotherapy-naive and scheduled for anthracycline-based treatment for stage I-III breast cancer.

Not a fit: Patients with a left ventricular ejection fraction below 53% or those with significant valvular heart disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved heart health and better treatment outcomes for breast cancer patients undergoing chemotherapy.

How similar studies have performed: Previous studies have shown some success with SGLT-2 inhibitors in reducing heart failure risks, but this specific application in chemotherapy-induced cardiotoxicity is novel.
