Absorption, Metabolism, and Excretion of [¹⁴C]‐Tivozanib, a Vascular Endothelial Growth Factor Receptor Tyrosine Kinase Inhibitor, in Healthy Male Participants: A Phase I, Open‐Label, Mass‐Balance Study

Abstract

Tivozanib had a long half-life with no major circulating metabolite, was well tolerated as a single dose, and was primarily eliminated via feces with no unchanged tivozanib found in urine. These pharmacokinetic data of [(14) C]-tivozanib are consistent with previous studies of unlabeled tivozanib.
