What this trial studies

This clinical trial aims to evaluate the effectiveness of Sacubitril/Valsartan in preventing cardiotoxicity associated with systemic breast cancer treatments. It is a multicenter, randomized, placebo-controlled trial involving approximately 600 patients across three Polish oncology centers. Participants will be randomly assigned to receive either the medication or a placebo, and their heart function will be monitored through echocardiography over a 24-month period. The primary endpoint is the occurrence of a significant decrease in left ventricular ejection fraction (LVEF).

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and over with early-stage breast cancer who are scheduled for radical treatment and have a baseline LVEF of 50% or higher.

Not a fit: Patients with prior anthracycline therapy, significant heart failure, or recent myocardial infarction will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the risk of heart damage in women undergoing treatment for breast cancer.

How similar studies have performed: While there have been attempts to prevent cardiotoxicity in cancer treatments, this specific approach using Sacubitril/Valsartan is novel and has not been extensively tested.
