The pharmacokinetics and metabolism of BIBF 1120, an oral triple angiokinase inhibitor targeting vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR), and fibroblast growth factor receptor (FGFR), were studied in healthy male volunteers (n?=?8) who had received a single oral dose of 100?mg [(14)C]-radiolabelled BIBF 1120 administered as solution. BIBF 1120 was well-tolerated and rapidly absorbed; median time to reach maximum plasma concentrations was 1.3?h and gMean terminal half-life was 13.7?h. A relatively high apparent total body clearance and volume of distribution possibly indicated a high tissue distribution. Plasma concentrations of BIBF 1120 plus carboxylate metabolite BIBF 1202 were lower than the total [(14)C]-radioactivity in plasma, indicating presence of additional metabolites. Total recovery in excreta was 94.7% 1 week post-dose; mass balance was considered complete after 96?h. BIBF 1120 and metabolites were mainly excreted via faeces. The major metabolic pathway for BIBF 1120 was methyl ester cleavage to BIBF 1202. Subsequently, the free carboxyl group of BIBF 1202 was glucuronidated to 1-O-acylglucuronide. Pathways of minor importance were oxidative N-demethylation to yield BIBF 1053, and oxidation of the piperazine moiety and conjugation. Glucuronidation of the parent drug and formylation of the secondary aliphatic amine of the piperazine ring played a minor role.
