Effect of Spironolactone in the Prevention of Anthracycline-induced Cardiotoxicity: a Randomized Clinical Trial (SPIROTOX Trial)

SPIROTOX

The goal of this clinical trial is to evaluate the effect of spironolactone in the primary prevention of cardiotoxicity in cancer patients who are undergoing chemotherapy with anthracycline within 12 months. The main question it aims to answer is: • Does spironolactone reduce the incidence of cardiotoxicity in patients undergoing anthracycline chemotherapy? Participants will: * Be cancer patients over 18 years starting treatment with anthracycline; * Be randomized to receive either spironolactone or a placebo for 1 year; * Undergo assessments of their left ventricular ejection fraction (LVEF), global longitudinal strain, and cardiac biomarkers over the 12-month period. Researchers will compare the spironolactone group to the placebo group to see if cardiotoxicity incidence differs between the two.
