Cancer drug Dasatinib also lowers blood glucose, finds retrospective study

Researchers used Mayo Clinic's Informatics for Integrating Biology at the Bedside, a framework that organizes and transforms patient records into a deidentified research database. The retrospective study started with a total of 9.3 million individuals who were screened for use of either dasatinib or imatinib, another tyrosine kinase inhibitor that was approved for treatment of a type of leukemia in 2001 but with weak senolytic activity. The records were for Mayo patients from 1994 to 2019. Of those patients, 279 were treated with imatinib and 118 with dasatinib, and after further screening, a total of 48 patients were included in the study.

The findings show that dasatinib lowers serum glucose in patients with pre-existing type 2 diabetes to a greater degree than imatinib and comparable to first-line diabetic medications such as metformin and sulfonylureas.

Further study is needed to determine whether the antidiabetic effect of dasatinib is due primarily to its senolytic properties, says Dr. Pignolo, director of the Translation and Pharmacology Program at Mayo Clinic's Robert and Arlene Kogod Center on Aging. If it is, the effectiveness of combining dasatinib with another senolytic drug such as quercetin may be greater than with dasatinib alone.

"This study was really the first proof-of-concept that a senolytic drug may have substantial long-term beneficial effects in humans," Dr. Pignolo says. "According to research in animal models, it is not necessary to give senolytic drugs continuously, and so patients may need only take a drug such as dasatinib every few weeks, reducing possible side effects."

The study was supported by the National Center for Advancing Translational Sciences; the Robert and Arlene Kogod Professorship in Geriatric Medicine at Mayo Clinic; the National Institute on Aging; the Noaber Foundation Professorship in Aging at Mayo Clinic; the Connor Group; the Robert J. and Theresa W. Ryan Foundation; and the Travelers Chair in Geriatrics and Gerontology at the University of Connecticut Health Center.
