About

EMPACT (EMPAgliflozin in prevention of chemotherapy-related CardioToxicity) study is a randomized, multi-center, placebo-controlled, double-blind trial to evaluate efficacy of empagliflozin in prevention of left ventricular (LV) dysfunction in patients receiving high cumulative doses of anthracyclines. Diagnosed with cancer, 220 patients without history of heart failure and LV ejection fraction (EF) ≥ 50%, scheduled for high dose anthracyclines (doxorubicin ≥240 mg/m2 or epirubicin ≥540 mg/m2), will be included in the study. They will be randomized to a 10 mg of empagliflozin once daily or to matching placebo in a 1:1 ratio. The primary objective of the EMPACT study is to assess whether prophylactic SGLT-2 inhibitors may prevent a reduction in LVEF after high doses anthracyclines, as evaluated by serial echocardiography on each visit and cardiovascular magnetic resonance (CMR) performed at randomization and on its completion. The secondary composite endpoint includes: all-cause death, cardiovascular (CV) death, myocardial infarction and ischemic stroke. Additional secondary outcome measures include structural myocardial alterations assessed by CMR, decrease in GLS (global longitudinal strain) in echocardiography and changes in cardiac biomarkers. The study will be carried out in accordance with GCP and monitoring will be outsourced to a subcontractor - CRO. The examination will be insured and will begin as soon as the required approvals are obtained.

Full description

Malignant neoplasms are the second most common cause of death in Poland. Cancer mortality decreased by 27% over the past 25 years. Improved survival in cancer patients is related to several factors, such as prevention, early detection and the introduction of new chemotherapy regimens. However, the benefits of administration of anti-cancer drugs are partially limited by their adverse effects on the cardiovascular system, resulting in increased morbidity and mortality from complications of this treatment. The most serious toxic effect of chemotherapy is damage to the heart muscle leading to its failure, often referred to as 'cardiotoxicity'. This serious complication remains an unresolved clinical problem. The use of doxorubicin is associated with the development of congestive heart failure even in 48% of patients at the doxorubicin total dose of 700 mg/m2. The only drug approved for the prophylactic treatment of cardiac complications is dexrazoxane. However, it is only recommended for patients with advanced breast cancer receiving doxorubicin or epirubicin who have previously received a cumulative dose of 300 mg/m2 of doxorubicin or a cumulative epirubicin dose of 540 mg/m2, when further anthracycline therapy is required. Dexrazoxane is an expensive drug and may influence the effectiveness of chemotherapy. Routine prophylaxis of myocardial dysfunction is not currently recommended due to insufficient data from randomized clinical trials. So far, the prophylactic effects of such cardiological drugs as: angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), beta-blockers, statins and ranolazine have been studied. The results of these studies are contradictory. Therefore, at present, only symptomatic patients with decreased left ventricular ejection fraction or elevated levels of cardiac biomarkers are eligible for treatment with heart failure medications. Empagliflozin is an orally administered once-daily, highly selective sodium-glucose cotransporter 2 (SGLT2) inhibitor proven to treat patients with chronic heart failure of different aetiologies, also with preserved left ventricle systolic function. This drug also has additional nephroprotective, anti-inflammatory and metabolic effects. In recent animal studies, the cardioprotective effect of empagliflozin during the use of anthracyclines was demonstrated.

EMPACT (EMPAgliflozin in prevention of chemotherapy-related CardioToxicity) study is a randomized, multi-center, placebo-controlled, double-blind trial to evaluate efficacy of empagliflozin in prevention of left ventricular (LV) dysfunction in patients receiving high cumulative doses of anthracyclines.

Additional secondary outcome measures include structural myocardial alterations assessed by CMR, decrease in GLS (global longitudinal strain) in echocardiography and changes in cardiac biomarkers. This is the first study of this type in the world, we hope that the results of this project will change the standards of management of oncological patients and contribute to the improvement of their survival and quality of life.
