简要总结
This was a Phase I study in 12 healthy male participants to compare the pharmacokinetic properties of CG5503 (how it is taken up and excreted from the body) after 2 minutes intravenous (i.v.) infusion with and without oral co-administration of charcoal to investigate a potential gastrointestinal secretion of CG5503.
During the course of the study each participant received two infusions of 40 mg CG5503 without (treatment A) and with (treatment B) oral co-administration of charcoal. In treatment B, eight doses of 5 grams charcoal powder were co-administered orally at defined time points. The wash out phases were to be at least 4 to 14 days between the treatment periods.

Minor deviations of laboratory values from the normal range may be accepted, if judged by the investigator to have no clinical relevance and if not considered to interfere with the study objectives.
