To evaluate the correlation between the degree of hepatic impairment based on liver biopsy
score (mi ld, moderate, severe) and plasma levels of nevirapine [Viramune] and its
Official title: Evaluation of Nevirapine Levels in Hepatically Impaired Patients
Study design: Treatment, Randomized, Open Label, Historical Control, Parallel Assignment
Primary outcome: The primary endpoints are the degree of hepatic impairment, steady state nevirapine clearance, and the increase in estimated clearance when trough is supplemented by plasma levels measured one, two and four hours after nevirapine administratio
Secondary outcome: Plasma levels of nevirapine metabolites of all patients and Child-Pugh scores among patients with cirrhosis.
Minimum age: 18 Years.
Maximum age: N/A.
1. Male or female subjects >=18 years of age with HIV-1 infection and chronic li ver
disease as reflected by a documented biopsy with hepatic fibrosis present.
2. a. Participants must be receiving nevirapine 200 mg twice daily as part of a stable
ARV regimen for a minimum of 6 weeks prior to trough level sample collec tion. b.
Participants receiving nevirapine 400 mg once daily as part of a stable ARV regimen
for a minimum of 6 weeks, who are willing to switch to nevirapine 20 0 mg twice daily
for a minimum of 14 days prior to trough collection.
3. Participants must have undergone a liver biopsy within 24 months prior to enr ollment
and have a pathology report and at least one Hematoxylin and Eosin (H and E) stained
slide and one trichrome stained pathology slide available at the time of enrollment.
There is no time restriction on liver biopsy slides that pathol ogically confirm the
presence of cirrhosis. The presence of cirrhosis must be d ocumented on the liver
