This open label phase I trial 1230.23 will investigate the pharmacokinetics (absorption, distribution, metabolism and excretion (ADME)) of the specific Polo-like kinase 1(PLK-1) inhibitor BI 6727 in tumour patients. Major tasks involve the structure elucidation of metabolites as well as the 14C-radioactivity in blood cells, plasma, urine and faeces. This study will also help in determining the metabolic pathways following intravenous administration of [14C]-radiolabelled BI 6727. Determination of human ADME is the primary endpoint of this trial. Human ADME will be evaluated in patients during the first BI 6727 treatment cycle only. If clinical benefit from BI 6727 treatment is indicated, patients may receive additional cycles of BI 6727. ADME will not be investigated in further cycles. Secondary endpoints of this trial are safety, tolerability and the assessment of preliminary therapeutic effects of BI 6727.
