UT Health San Antonio researchers, collaborating with the Mayo Clinic and the Wake Forest School of Medicine, are the first to publish results on the treatment of a deadly age-related disease in human patients with drugs called senolytics. The findings were posted Jan. 4 by the journal EBioMedicine,which is published by The Lancet.
Each participant received two senolytic drugs, dasatinib and quercetin (DQ), taken by mouth for three consecutive days each week for three consecutive weeks (nine doses total). All patients were able to comply with this regimen without any discontinuation of the study drugs.
Results
The most consistent improvements following senolytic therapy were observed in participants' mobility. The six-minute walk test, timed sitting-to-standing repetitions and other measures were significantly improved after completion of the treatment. The majority of patients exhibited mobility gains of greater than 5 percent. Other physical function markers, including grip strength and pulmonary function testing, did not change.
"No drug therapies, including the available anti-fibrotic drugs, have ever shown to stabilize, let alone improve, an IPF patient's six-minute walk distance," Dr. Nambiar said. "But in this pilot study of DQ, participants' six-minute walk distance improved an average of 21.5 meters.
