Clinical Trial Summary

The purpose of this study is to learn more about the safety and tolerability of etravirine. Etravirine is a type of non-nucleoside reverse transcriptase inhibitor (NNRTI) which has shown high activity against wild-type human immunodeficiency virus (HIV-1), and HIV strains resistant to other non-nucleotide agents.


Clinical Trial Description

This is an open-label (all people involved know the identity of the intervention), single arm, multicenter Phase IV study to evaluate the safety, tolerability, and pharmacokinetics of etravirine (ETR) in combination with antiretroviral (ARV) therapy other than darunavir (DRV) + ritonavir (rtv). In addition, the antiviral activity and the pharmacokinetic/pharmacodynamic profile, and safety of ETR will be assessed. The study will consist of a screening period of maximum 6 weeks, a baseline visit, and a 48-week treatment period. After the end of the treatment period, patients with ongoing adverse events (AEs) will be followed for an additional 4 weeks. At least 200 ARV treatment-experienced human immunodeficiency virus (HIV-1) infected patients will be enrolled in this study. Patients will be considered ARV treatment-experienced if they have been on their current stable highly active antiretroviral therapy (HAART) regimen for at least 8 weeks prior to screening. The study population will consist of patients who need to change their current HAART regimen due to any of the following reasons: (1) patients experiencing virologic failure (with a screening viral load value >=500 HIV-1 RNA copies/mL), or (2) patients switching due to simplification of their current regimen or due to AEs and/or tolerability reasons (with a screening viral load value <50 HIV-1 RNA copies/mL). Patients will receive ETR 200 mg twice daily in combination with an investigator-selected background regimen. In addition to ETR, which needs to be active based on resistance testing, the background regimen should consist of at least 1 active ARV resulting in a treatment regimen with at least 2 active ARVs. The following exceptions to this are: (1) if raltegravir (RAL) or atazanavir/ritonavir (ATV/rtv) are part of the background regimen, the number of active ARVs in this background regimen should be at least 2; (2) low-dose ritonavir should not be counted as an active ARV. DRV/rtv will not be allowed in the background regimen in order to evaluate the safety and pharmacokinetics of ETR in combination with ARVs other than DRV/rtv. Furthermore, a background regimen consisting of nucleoside transcriptase inhibitors (NRTIs) only will not be allowed. The background regimen cannot be modified until the end of the treatment period with the following exception: switches within the ARV class will be allowed for well documented tolerability/toxicity reasons. For patients who, in the opinion of the investigator, are deriving clinical benefit from ETR, and to whom ETR is not commercially available in his/her country, is not reimbursed or cannot be accessed from another source (e.g., access program, government program) in the region the patient is living in, the possibility to extend their ETR treatment period will be provided. The ETR tablets are to be taken orally twice daily after a meal. A total daily dose of 400 mg is to be taken for 48 weeks. ;
