Grape Polyphenols for Prevention of Chemotherapy-Induced Cardiotoxicity

Starting soon · Not applicable · Has a placebo group

Conditions studied: Chemotherapy-induced Cardiotoxicity, Breast Cancer

In brief

This pilot randomized clinical study aims to evaluate the cardioprotective effects of a grape polyphenol concentrate in patients receiving anthracycline- and/or trastuzumab-based chemotherapy. Adult patients at high or very high risk of chemotherapy-induced cardiotoxicity will be randomized to receive either a grape polyphenol concentrate or placebo for three months, starting with chemotherapy. Cardiac function and cardiotoxicity will be assessed using echocardiographic parameters and circulating biomarkers at baseline, 3 months, and 6 months.
