Descriptive Information
Brief Title  ICMJE Study Examining The Effect Of Hepatic Impairment On Safety, Toleration And How The Body Processes An Experimental Drug
Official Title  ICMJE A Phase 1, Open-Label, Parallel Group, Multiple-Dose Study To Evaluate The Pharmacokinetics, Safety And Toleration Of CP-945,598 Administered To Subjects With Impaired And Normal Hepatic Function
Brief SummaryCP-945,598 is eliminated following extensive metabolism. Decrease hepatic function can affect its elimination from the body via metabolism. This study will therefore compare the pharmacokinetics (time course of drug concentrations in the body), safety, and tolerability of CP-945,598 in patients with mild and moderate hepatic impairment and healthy control subjects.
