Rosuvastatin for Prevention of Anthracycline-induced Cardiac Dysfunction in Breast Cancer Patients (ROSUBREAST)

December 3, 2025 updated by: Armin Attar, Shiraz University of Medical Sciences

Evaluation of Rosuvastatin Efficacy in Prevention of Anthracycline-induced Cardiac Dysfunction in Breast Cancer Patients After Chemotherapy

This study, called "ROSUBREAST", is a multicenter, double-blind, randomized clinical trial evaluating whether rosuvastatin (20 mg daily) can protect the heart in women with breast cancer receiving anthracycline-based chemotherapy. A total of 400 participants will be randomly assigned to receive either rosuvastatin or placebo for 12 months. The main goal is to determine whether rosuvastatin can prevent cancer treatment-related cardiac dysfunction (CTRCD), defined as a significant drop in heart pumping function. The study will also assess changes in cardiac strain, blood biomarkers, symptoms of heart failure, quality of life, and possible side effects.

Detailed Description

Introduction: Anthracycline-induced cardiotoxicity significantly threatens the long-term cardiac health of breast cancer patients undergoing chemotherapy. Statins have shown potential cardioprotective effects without compromising cancer treatment efficacy. The ROSUBREAST study aims to evaluate the efficacy of rosuvastatin in preventing CTRCD in breast cancer patients receiving anthracycline-based chemotherapy. Methods: This multicenter, two-arm, double-blinded, superiority, parallel-group, randomized, placebo controlled clinical trial will be conducted across seven oncocardiology centers in Iran. A total of 400 participants will be enrolled and will be randomly assigned in a 1:1 ratio to receive either rosuvastatin (20 mg daily) or no intervention for 12 months. The primary endpoint is the incidence of CTRCD, defined as a ≥10% reduction in left ventricular ejection fraction (LVEF) to below the lower normal limit (53%). Secondary endpoints include changes in Global Longitudinal Strain (GLS), biomarkers (Troponin, NT-proBNP, hsCRP), and development of heart failure (HF). Ancillary endpoints are quality-of-life assessments and adverse effects of treatment. Conclusion: The ROSUBREAST study seeks to provide evidence on the cardioprotective role of rosuvastatin in breast cancer patients undergoing anthracycline-based chemotherapy, potentially informing clinical guidelines and improving patient outcomes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
