Sodium-Glucose Cotransporter 2 Inhibitors During Cancer Therapy: Benefits, Risks, and Ongoing Clinical Trials.

Purpose Of Review: The goal of this paper is to summarize the data pertaining to the use of sodium-glucose cotransporter-2 inhibitors (SGLT-2i) for the prevention of cardiotoxicity in patients receiving anthracyclines for cancer treatment. We discuss the potential efficacy of this class of medications, incorporating insights from existing literature and ongoing studies.

Recent Findings: SGLT2i are a class of medications which were initially developed for treatment of Type 2 diabetes and later extended to treat heart failure with reduced and preserved ejection fraction regardless of diabetes status. There remains a need for effective and safe treatments to preventing cardiotoxicity in anthracycline-treated patients. It has been proposed that SGLT2i may provide protection against the cardiotoxic effects of anthracyclines. Some of the proposed mechanisms include beneficial metabolic, neurohormonal, and hemodynamic effects, renal protection, as well as a decrease in inflammation, oxidative stress, apoptosis, mitochondrial dysfunction and ion homeostasis. There is emerging evidence from basic science and observational studies that SGLT2i may play a role in the prevention of chemotherapy-induced cardiotoxicity. Randomized controlled trials are needed to conclusively determine the role of SGLT2 inhibitors as a cardioprotective therapy in patients receiving anthracyclines for the treatment of cancer.
