Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 16 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2015-06-22
• Study Completion Date: 2016-09-16

Brief Summary

This will be a Phase 1, open-label, parallel group, two-part, single-dose adaptive study in adults with moderate and mild (if needed) hepatic impairment and matched, healthy control subjects with normal hepatic function. In Part 1, healthy control subjects (n=8) matched to subjects with moderate (n=8) hepatic impairment will be enrolled. If the geometric mean total plasma area under the concentration-time curve from time zero (pre-dose) extrapolated to infinite time (AUC[0-infinity]) of GSK1265744 is increased by >2-fold in moderately impaired subjects relative to matched controls, Part 2 will be conducted to evaluate GSK1265744 PK in subjects with mild hepatic impairment (n=8) and matched, control subjects (n=8). All subjects will receive a single 30 milligram (mg) oral dose of GSK1265744. The primary objective of the study is to compare plasma PK parameters of GSK1265744 in subjects with hepatic impairment to healthy controls matched in gender, age, and body mass index (BMI).
