E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy of 400 mg QD nevirapine extended release (NVP XR) formulation versus 200 mg BID nevirapine immediate release (NVP IR) in ARV therapy naïve HIV-1 infected patients after 48 weeks of treatment. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to evaluate safety and pharmacokinetics of NVP XR and NVP IR. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Optional Pharmacokinetic Substudy: Designated trial centers will participate in the pharmacokinetic substudy that includes intensive blood collection on Day 28. It is planned to include approximately 30 patients within this substudy. A patient who qualifies for the trial will automatically qualify for the PK substudy. A separate informed consent form will be required for participation in the substudy. Only study centers with previous experience and equipped in handling PK samples are eligible for participation in the substudy. It is anticipated that enrollment for the PK substudy will be finished before completion of the main study. In this case, the sponsor will inform the designated centers to continue enrollment for the main study without further enrollment into the PK substudy. |

Use of immunomodulatory drugs within 30 days before study entry or during the trial (e.g., interferon, cyclosporin, hydroxyurea, interleukin 2) 12. Patients who have been diagnosed with malignant disease 13. Patients who in the opinion of the investigator are not candidates for inclusion in the study 14. Patient with Progressive Multifocal Leukoencephalopathy (PML), Visceral Kaposi's Sarcoma (KS), and/or any lymphoma 15.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of this study is virologic response by Week 48. Virologic response is defined as VL <50 copies/mL prior to Week 48 and without subsequent virologic rebound or change of ARV therapy prior to Week 48. A virologic rebound is defined by two consecutive measurements of VL ≥500 copies/mL, at least two weeks apart, after the measurement of VL <50 copies/mL. If the first VL ≥500 copies/mL occurs at Week 48 and this is the first sequential VL value ≥500 copies/mL following virologic response, then another measurement at least two weeks later is necessary to confirm whether virologic rebound has occurred.

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
An end of trial (EOT) visit will be performed when a patient either completes the entire trial at Week 144 or discontinues early (note: Week 144 is the maximum treatment duration allowed for each patient). This visit should occur within one week of the last dose of study drug to evaluate efficacy, AEs/SAEs and the final laboratory test results. The EOT visit for early discontinuation is conducted to collect efficacy and safety information from patients who discontinue from Trial 1100.1486.
