Abstract:OBJECTIVE: The PRevention of cArdiac Dysfunction during Adjuvant breast cancer therapy (PRADA) study is a randomized, placebo-controlled, double-blind trial to determine whether angiotensin receptor blockers (ARB), or beta-blockers or their combination may prevent the development of left ventricular (LV) dysfunction in patients on standard adjuvant treatment for early breast cancer. METHODS: Following surgical resection, 120 breast cancer patients scheduled for adjuvant epirubicin-containing chemotherapy and, if indicated, trastuzumab, will be included. They will be randomized to an ARB (candesartan), a beta-blocker (metoprolol) and matching placebos in a 2 x 2 factorial design. The primary objective of the PRADA study is to assess whether prophylactic ARB and/or beta-blockers may prevent a reduction in LV ejection fraction (EF) after adjuvant treatment of early breast cancer, as evaluated by serial cardiovascular magnetic resonance (CMR) performed at randomization, after the first chemotherapy cycle and on its completion, and for subgroups, on completion of radiotherapy or trastuzumab. Secondary outcome measures include echocardiographic indices of LV diastolic dysfunction, structural myocardial alterations assessed by CMR and changes in cardiac biomarkers. CONCLUSION: PRADA may provide new information on the prophylactic effect of ARB and beta-blockers in patients with early breast cancer regarding the risk of developing cardiac dysfunction from adjuvant cancer treatment.
