Isoquercetin as an Adjunct Therapy in Patients With Kidney Cancer Receiving First-line Sunitinib: a Phase I/II Trial

Summary

Advanced renal cell carcinoma is invariably fatal, with a life expectancy of 2-3 years since diagnosis. Sunitinib is the standard first-line treatment for this condition, but it is associated to multiple side effects, with fatigue being reported in 51-63% of patients. As sunitinib-induced fatigue is likely to be mediated by inhibition of AMPk function, the investigators hypothesize that isoquercetin, which is hydrolyzed in vivo to quercetin, a known AMPk activator, is able to reduce fatigue in kidney cancer patients taking sunitinib.
