Brief Summary:
The purpose of this trial is to compare the effectiveness, safety and tolerability of TMC278 given at a dose of 25 mg once daily versus efavirenz (EFV) at a dose of 600 mg once daily, when combined with a fixed background regimen consisting of emtricitabine (FTC) + tenofovir disoproxil fumarate (TDF), in HIV-1 infected patients who have not yet taken any anti-HIV drugs. The following evaluations will be done: antiviral activity, immunologic changes, and viral geno-/phenotype evolution, relationship of Pharmacokinetics (PK) and PK/Pharmacodynamics, medical resource utilization and treatment adherence.

Condition or disease Intervention/treatment Phase
HIV Infections HIV-1 Human Immunodeficiency Virus Type 1 Drug: TMC278 Drug: Efavirenz Phase 3

Detailed Description:
Over the past decade, anti-human immunodeficiency virus (HIV) drugs have been introduced sequentially for use in the clinic. Currently, patients are routinely being treated with 3 or 4 drug combinations including nucleoside/tide analogue reverse transcriptase inhibitors (NRTIs/NtRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), and/or fusion inhibitors. New potent antiretroviral (ARV) compounds that work in people whose HIV-1 virus is resistant to available drugs are urgently needed. This is a Phase III, randomized (study medication is assigned by chance), double-blind (neither the study physician nor the patient knows the name of the study assigned medication), double-dummy, active-controlled trial to compare the effectiveness, safety, and ability to tolerate TMC278 versus efavirenz (EFV). The study will last for 104 weeks which includes a screening period of 4 weeks, a 96-week treatment period, followed by a 4 week follow-up period. Patients will be randomly assigned to TMC278 or to efavirenz, either of these treatments will be in combination with two other anti-HIV drugs (2 NRTIs: emtricitabine (FTC) + tenofovir (TDF)). TDF/FTC will be administered as a fixed dose combination if available. The hypothesis to be provided in this study is that the investigational drug TMC278 will perform just like efavirenz (EFV) in terms of antiviral effectiveness (i.e., suppressing of the plasma viral load to a level < 50 HIV-1 RNA (ribonucleic acid) copies/mL) in ARV-naïve HIV-infected patients. During the trial, patients' health will be monitored by physical examination, interview to assess health and well being, and laboratory testing on blood and urine samples. Experimental Group: One tablet of TMC278 25 mg once daily plus one tablet of placebo once daily that looks just like efavirenz (EFV) plus tenofovir/emtricitabine; Control Group: One tablet of Placebo once daily that looks just like TMC278 plus EFV 600 mg once daily plus tenofovir/emtricitabine.

Primary Outcome Measures :
  1. Number of Participants With Virological Response (Intent-to-Treat - Time to Loss of Virologic Response [TLOVR], <50 Copies/ml) at Week 48 [ Time Frame: Week 48 ]
    Virological response is defined as confirmed plasma viral load less than (<) 50 human immunodeficiency virus-1 (HIV-1) (ribonucleic acid [RNA]) copies/milliliter (ml) at Week 48. The TLOVR algorithm was used to derive response. Response needed to be confirmed at 2 consecutive visits and participants who permanently discontinued were considered nonresponders after discontinuation. Resuppression after confirmed virologic failure was considered as failure. Virologic Failure includes participants who were rebounder (confirmed viral load >= 50 copies/ml after being responder) or who were never suppressed (no confirmed viral load <50 copies/ml).

Secondary Outcome Measures :
  1. The Number of Participants With Virological Response (Intent-to-Treat - Snapshot, <50 Copies/ml) at Week 48 [ Time Frame: Week 48 ]
    The analysis is based on the last observed viral load (VL) data within the Week 48 window. Virologic response is defined as a VL<50 copies/ml (observed case). Missing VL was considered as non-response. Virologic Failure includes subjects who had VL>=50 copies/ml in the Wk48 window, subjects who discontinued early due to lack or loss of efficacy, subjects who discontinued for reasons other than an adverse event, death or lack or loss of efficacy and at the time of discontinuation had a VL>=50 copies/ml and subjects who had a switch in background regimen that was not permitted by the protocol.

  2. Number of Participants With Virological Response (Intent-to-Treat - Time to Loss of Virologic Response [TLOVR], <50 Copies/ml) at Week 96 [ Time Frame: Week 96 ]
  3. The Number of Participants With Virological Response (Intent-to-Treat - Snapshot, <50 Copies/ml) at Week 96 [ Time Frame: Week 96 ]
  4. Number of Participants With Virological Response (Observed, <50 Copies/ml) at Last On-Treatment Visit (Post-Week 96). [ Time Frame: Variable, ranging from 3 months up to maximum 15 months for TMC278 and 12 months for Efavirenz after the 96-week visit ]
    Virological response is defined as (observed) plasma viral load less than 50 human immunodeficiency virus-type 1 (HIV-1) ribonucleic acid (RNA) copies per ml at the last on-treatment visit (post-Week 96).

  5. Number of Participants With Virological Response (Intent-to-Treat - Time to Loss of Virologic Response [TLOVR], <400 Copies/ml) at Week 48 [ Time Frame: Week 48 ]
  6. Number of Participants With Virological Response (Intent-to-Treat - Time to Loss of Virologic Response [TLOVR], <400 Copies/ml) at Week 96 [ Time Frame: Week 96 ]
  7. Mean Change From Baseline to Week 48 and Week 96 in Absolute and Relative CD4+ Cell Counts (Using Imputed Data) [ Time Frame: Baseline, Week 48, and Week 96 ]
    Change from baseline in CD4+ cell count was imputed in case of missing values: in case of premature discontinuation, data were imputed with the baseline value after discontinuation (i.e. change=0, Non-Completer [NC] = Failure); otherwise last observation carried forward was applied.

  8. Number of Participants With Virologic Failure for the Resistance Determination by Emerging Resistance Associated Mutations: First Available On-Treatment Genotypic Data After Failure [ Time Frame: Week 96 ]
    Virologic failure for the resistance determinations was defined as lack of virologic response (never having had 2 consecutive plasma viral load <50 copies/mL) and plasma viral load increase of >=0.5 log 10 copies/mL above nadir (i.e., never suppressed), or confirmed loss of virologic response (2 consecutive plasma viral load >=50 copies/mL after having had 2 consecutive plasma viral load <50 copies/mL; i.e., rebounder), or discontinued with a last observed on-treatment plasma viral load >=50 copies/mL after having had 2 consecutive plasma viral load <50 copies/mL. For this study, treatment-emergent reverse transcriptase (RT) resistance associated mutations (RAMs) occurring in at least 2 virologic failures (for at least one treatment group) for the following lists are presented: i) Extended list of Non-nucleoside reverse transcriptase inhibitor (NNRTI RAMs) ii) IAS-USA list of Nucleoside/tide reverse transcriptase inhibitor (N[t]RTI RAMs).
