Summary

This is a Phase 1, open-label, parallel-group, single-dose study of lofexidine in 6 adult subjects with mild hepatic impairment (Child Pugh score of 5 6), 6 adult subjects with moderate hepatic impairment (Child Pugh score 7 9), 6 adult subjects with severe hepatic impairment (Child Pugh score 10 15), and 6 control subjects with normal hepatic function with mean age, body mass index (BMI), and gender distribution targeted to be similar to the impaired hepatic function cohorts.

Detailed description

This is a Phase 1, open-label, parallel-group, single-dose study of lofexidine in 6 adult subjects with mild hepatic impairment (Child Pugh score of 5 6), 6 adult subjects with moderate hepatic impairment (Child Pugh score 7 9), 6 adult subjects with severe hepatic impairment (Child Pugh score 10 15), and 6 control subjects with normal hepatic function with mean age, body mass index (BMI), and gender distribution targeted to be similar to the impaired hepatic function cohorts. Subjects will be confined to an inpatient facility from the evening before dosing to 144 hours after dosing. Subjects who successfully complete screening will report to the inpatient facility at an appropriate time the evening before study drug administration (Day 1) to ensure a minimum 10 hour fast. The next morning (Day 1) while still fasting, subjects will receive a single, oral dose of 400 µg lofexidine HCl (two 200 µg tablets). Blood samples will be collected for pharmacokinetic (PK) analysis at multiple time points over the next 144 hours (Day 7). Pooled urine samples will be collected at 0 3 hours, 3 6 hours, 6 12 hours, 12 24 hours, 24 48 hours, 48 96 hours, 96 120 hours and 120 144 hours post-dose. Safety will be assessed by recording adverse events (AEs), measuring vital signs (blood pressure and pulse rate) and clinical laboratory tests (chemistry, hematology, and urinalysis), recording 12 lead safety and Holter electrocardiograms (ECGs), and performing physical exams.
