TMC125-TiDP2-C238: An Exploratory Pharmacokinetics, Safety and Anti-HIV Activity Study of Etravirine (ETR) When Given With Boosted Atazanavir (ATV/Rtv) at Two Different Doses and 1 Nucleoside Reverse Transcriptase Inhibitor (NRTI) in Treatment Experienced HIV Patients
September 27, 2013 updated by: Janssen R&D Ireland
TMC125-TiDP2-C238: A Randomized, Exploratory, Open-label 48-week Trial to Investigate the Pharmacokinetics, Safety, Tolerability and Antiviral Activity of Etravirine (ETR) in Combination With Ritonavir-boosted Atazanavir (ATV/Rtv) and 1 NRTI in Treatment-experienced HIV-1 Infected Subjects
The purpose of this study is to determine the pharmacokinetics (how the body absorbs, distributes, metabolizes and eliminates a drug) (PK) of ETR when given with ATV/rtv and 1 NRTI in treatment experienced HIV-1 infected patients.
In addition, safety, tolerability and anti-HIV effect of this regimen will also be studied.
A total of 46 patients will be enrolled.

Detailed Description
This is a randomized (study drug assigned by chance), exploratory, open-label (all involved people know the identity of the intervention) trial to evaluate the pharmacokinetics (PK), safety, tolerability and anti-HIV (anti Human Immunodeficiency Virus) activity of etravirine (ETR ) when given with atazanavir/ritonavir (ATV/rtv) and 1 nucleoside reverse transcriptase inhibitor (NRTI) in 46 treatment experienced HIV-1 infected patients.
The trial will consist of : 4 weeks of Screening Period, 2 weeks Pre-Treatment Phase, 48-week Treatment Period, and a Final Visit followed by a 4-week Follow-up Period (only for patients not continuing treatment with ETR in another trial or program).
Safety evaluations (AE reporting, labs, vital signs, etc.) will be monitored at each study visit.
A PK substudy (included in the protocol, with optional participation) with tenofovir (TDF) added to the antiretroviral regimen for 7 days will be conducted in patients with > 24 weeks of treatment with suppressed HIV-1 viral load.
In Pre-Treatment Phase, all patients will receive ATV/rtv 300/100 mg once daily to be taken following a meal each morning + 2 NRTIs (dose as specified in the labels) for 14 days.
In Treatment Phase, patients will receive ETR 200 mg twice daily in addition to ATV/rtv (300/100 mg or 400/100 mg) once daily with meals + 1 investigator-selected NRTI for 48 weeks.
In substudy TDF 300 mg once daily will be added to the treatment regimen x 7 days.

Time to virologic failure was the time to subsequent loss of virologic response, and the time was calculated from Prebaseline (Week -2).
Participants who never achieved a virologic response were defined as nonresponders and counted as virologic failures on Day 1.
