Prevention of Cardiac Dysfunction During Adjuvant Breast Cancer Therapy — PRADA  

Breast Cancer Clinical Trial

Official title: Prevention of Cardiac Dysfunction During Adjuvant Breast Cancer Therapy: A Randomized, Placebo-controlled, 2x2 Factorial, Double Blind Trial of Candesartan and Metoprolol

Status Completed

Clinical Trial Summary

Women treated for breast cancer are at increased risk for cardiovascular disease, including heart failure. In this study, by using magnetic resonance imaging (MRI), the investigators want to assess if heart failure medications such as beta blockers and angiotensin receptor blockers can prevent cardiac dysfunction during early breast cancer therapy.

Clinical Trial Description

Breast cancer is one of the most common malignancies in women. Recent progress in the detection and treatment of breast cancer has resulted in survival gains, but a consequence of therapeutic advances is an increasing number of long-term survivors who may be at risk for development of cardiovascular disease. Several studies suggest that women treated for breast cancer may be at increased risk for cardiovascular disease, the probable causes being multi-factorial. Importantly, therapies for breast cancer, including radiotherapy, anti-HER-2 regimens and certain chemotherapeutic regimens, may increase the risk of subsequent cardiovascular disease, including atherosclerotic disease, left ventricular dysfunction, and heart failure.

In the current study we propose to undertake a randomized, placebo-controlled, 2x2 factorial, double-blind trial to assess whether left ventricular dysfunction and/or injury is preventable, completely or partly, by the concomitant administration of the angiotensin receptor blocker (ARB), candesartan, and the beta blocker, metoprolol, during postoperative chemotherapy and radiotherapy.

The proposed study addresses an important clinical problem in a large patient group. Thus, the possibility of preventing cardiovascular side effects of contemporary therapy for breast cancer is important both clinically and scientifically. ;
