Trial Outcomes & Findings for A Study to Assess Pharmacokinetics of Preladenant in Participants With Chronic Hepatic Impairment (P06513) (NCT NCT01465412)

NCT ID: NCT01465412

Last Updated: 2018-09-24

Results Overview

For healthy and HI participants blood samples were collected at pre-dose (0 hour) and at 0.50, 1, 2, 4, 6, 12, 16, 24, 30, 36, and 48 hours postdose. Blood samples were also collected for HI participants only at 60 and 72 hours postdose in order to determine the AUC 0-t of preladenant.

PRIMARY outcome

Timeframe: Pre-dose up to 72 hours postdose

Population: All participants who received an oral dose of preladenant and for whom at least one pharmacokinetic parameter can be calculated for the treatment phase according to the protocol and who did not have any protocol deviation interfering with pharmacokinetics.

For healthy and HI participants blood samples were collected at pre-dose (0 hour) and at 0.50, 1, 2, 4, 6, 12, 16, 24, 30, 36, and 48 hours postdose. Blood samples were also collected for HI participants only at 60 and 72 hours postdose in order to determine the AUC 0-t of preladenant.
