Brief summary

The main study is a single arm, open-label, prospective study to assess antiretroviral activity and tolerability of etravirine (TMC-125) 400 mg once daily, given with fixed-dose tenofovir/emtricitabine, in treatment-naïve HIV-1-infected men and women. There are also a genital secretions pharmacokinetic (PK) sub-study and a metabolic sub-study. The purpose of the genital secretions PK sub-study is to gain information about drug levels and HIV-1 RNA in genital secretions when subjects are taking etravirine. The purpose of the metabolic sub-study is to learn about the effects of etravirine on body composition, as well as lipid and glucose levels.

Detailed description

Participants: There will be approximately 80 HIV-1-infected men and women aged 18 years or older who have taken less than or equal to 10 days of prior antiretroviral therapy and have never taken etravirine, dapivirine (TMC120), or rilpivirine (TMC 278) in the main study. There will be approximately 40 subjects who enroll in the main study that will be in the metabolic sub-study and approximately 20 subjects (10 pre-menopausal women and 10 men) who enroll in the main study that will be in the genital secretions PK sub-study. Procedures (methods): For the main study subjects will take etravirine 400 mg once daily orally with fixed-dose tenofovir/emtricitabine (Truvada) one tablet once daily. For the genital secretions PK sub-study, genital secretion samples will be self-collected throughout the study except for the week 4 study visit where women will have the cervicovaginal sample at time 0 and at 24 hours collected by study staff. For the metabolic sub-study, waist measurements and dual energy x-ray absorptiometry (DEXA) scans will be performed at entry, week 24, and week 96, and 2-3 teaspoons of blood to check lipids, insulin, and glucose will be taken at entry and weeks 12, 24, 48, and 96.

Interventions

DRUGTruvada

Etravirine 400 mg (four 100 mg or two 200 mg tablets) taken orally once a day with one pill of Truvada (200 mg of emtricitabine and 300 mg of tenofovir) taken orally once a day

Modification of tenofovir/emtricitabine was not a safety/tolerability event. The Kaplan-Meier method was used to estimate the proportion of participants ever exposed to etravirine who remained event-free through Week 96, with a 95% CI using Greenwood's variance estimate and a log-log transformation.

Change in Glucose Metabolism (Insulin Resistance), in a Subgroup of up to 40 Participants, From Baseline to Week 96 of Treatment With Etravirine and Fixed-dose Tenofovir/Emtricitabine

Metabolic data analyses were conducted as-treated. Insulin resistance was estimated by the homeostasis model assessment of insulin resistance (HOMA-IR), and was calculated as \[fasting insulin (µU/mL) × fasting glucose (mmol/L)\]/22.5. Changes from baseline to follow-up were calculated using the value closest to schedule and within the analysis window, and were quantified with the median and inter-quartile range.
