Cardioprotection Effect of Linagliptin (Linagliptin)

9 oktober 2026 uppdaterad av: Mai Abo Elyazeed Hassan Hamouda, Tanta University

Cardio-protective Effect of Linagliptin in Women With Breast Cancer Receiving Doxorubicin-Based Chemotherapy

1. Background and Rationale Breast cancer is one of the most common malignancies affecting women worldwide and represents a major health burden in Egypt. Anthracyclines, particularly doxorubicin, remain an important component of several breast cancer chemotherapy regimens. However, their clinical utility is limited by the potential development of anthracycline-induced cardiotoxicity.

Doxorubicin-induced cardiac injury is multifactorial and involves oxidative stress, mitochondrial dysfunction, disturbances in myocardial energy metabolism, apoptosis, inflammation, and progressive myocardial structural damage. Cardiac injury may initially occur without symptoms or an obvious reduction in left ventricular ejection fraction (LVEF). Consequently, identification of early myocardial injury is important because intervention before clinically apparent heart failure may potentially reduce progression to overt cardiac dysfunction.

1. Background and Rationale Breast cancer is one of the most common malignancies affecting women worldwide and represents a major health burden in Egypt. Anthracyclines, particularly doxorubicin, remain an important component of several breast cancer chemotherapy regimens. However, their clinical utility is limited by the potential development of anthracycline-induced cardiotoxicity.

Doxorubicin-induced cardiac injury is multifactorial and involves oxidative stress, mitochondrial dysfunction, disturbances in myocardial energy metabolism, apoptosis, inflammation, and progressive myocardial structural damage. Cardiac injury may initially occur without symptoms or an obvious reduction in left ventricular ejection fraction (LVEF). Consequently, identification of early myocardial injury is important because intervention before clinically apparent heart failure may potentially reduce progression to overt cardiac dysfunction.

The European Society of Cardiology recommends cardiovascular assessment and surveillance in patients receiving potentially cardiotoxic cancer therapies. Cardiac troponin (cTn) and natriuretic peptides may be used as biomarkers of cancer therapy-related cardiovascular toxicity, while echocardiography, including LVEF and global longitudinal strain (GLS) where available, provides complementary information about cardiac function.

Cardiac troponin is a highly specific biomarker of myocardial injury. According to the Fourth Universal Definition of Myocardial Infarction, myocardial injury is defined by a cardiac troponin concentration above the assay-specific 99th-percentile upper reference limit, while an acute injury is characterized by a rise and/or fall in troponin values.

Dipeptidyl peptidase-4 (DPP-4) inhibitors are primarily used as glucose-lowering agents in patients with type 2 diabetes mellitus. Linagliptin is a selective DPP-4 inhibitor administered at a standard dose of 5 mg once daily. Large cardiovascular-outcome data have demonstrated cardiovascular safety of linagliptin in patients with type 2 diabetes at high cardiovascular and renal risk, including no significant increase in hospitalization for heart failure compared with placebo.

However, whether linagliptin can prevent anthracycline-associated myocardial injury in women with breast cancer without diabetes remains insufficiently established. This creates a clinically relevant research gap.

Therefore, the proposed study will investigate whether prophylactic linagliptin, administered during doxorubicin-containing chemotherapy, can attenuate biochemical evidence of myocardial injury assessed by cardiac troponin and reduce the development of cardiac dysfunction.
