Incretin-Based Therapies in Doxorubicin-Induced Cardiotoxicity: A Systematic Review of GLP-1 and Dual GIP/GLP-1 Agonists.

Khatami S, Faghihi M, Tavakoli G, et al. Cardiovascular toxicology. 2026.

Editor's note

This review pools thirteen small rodent studies and reports incretin therapies were associated with better left ventricular function during doxorubicin exposure. Semaglutide and tirzepatide each appear in only a handful of animal studies, and the authors rate certainty as low-to-very-low. Findings are explicitly hypothesis-generating with no human data, so weight is limited.

Plain-language abstract

A systematic review of rodent studies found that incretin-based drugs, including semaglutide and tirzepatide, were associated with preserved heart function during doxorubicin chemotherapy, though no human studies existed.
