A Study to Determine the Safety and Efficacy of Rilpivirine in Treatment-naive Indian Participants With Human Immunodeficiency Virus Type 1 (HIV-1) Infection

Study Overview
=================
Brief Summary
-----------------
The primary purpose of the study is to evaluate the efficacy of rilpivirine (RPV)-based regimen in human immunodeficiency virus type 1 (HIV-1) infected, antiretroviral (ARV) treatment-naive participants, as determined by the percentage of virologic responders defined as having HIV-1 ribonucleic acid (RNA) less than 400 copies/ milliliter (mL) at Week 24.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants who are Virologic Responders (HIV-1 RNA <400 Copies/mL) at Week 24 | Virologic responders are defined as participants having viral load (plasma Human Immunodeficiency Virus-Type 1 Ribonucleic Acid [HIV-1 RNA] levels) less than (<) 400 copies/milliliter (mL) at Week 24 (Food and Drug Administration [FDA]-defined snapshot analysis). | Week 24 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants who are Virologic Responders (HIV-1 RNA <50 Copies/mL) at Week 24 | Virologic responders are defined as participants having viral load (plasma HIV-1 RNA levels) <50 copies/mL at Week 24 (FDA-defined snapshot analysis). | Week 24 | 
| Percentage of Participants who are Virologic Responders (Plasma HIV-1 RNA Levels <50, <400 and <1,000 Copies/mL) at Week 48 | Virologic responders are defined as participants having viral load (plasma HIV-1 RNA levels) <50, <400 and <1,000 copies/mL at Week 48 (FDA-defined snapshot analysis). | Week 48 | 
| Absolute Value in Cluster of Differentiation 4 Positive (CD4+) T-Cell Count at Weeks 24 and 48 | CD4+T cell absolute counts will be determined at Weeks 24 and 48. | At Weeks 24 and 48 | 
| Change from Baseline in CD4+ T Cell Count at Weeks 24 and 48 | Change from baseline in CD4+ T cell count will be determined at Weeks 24 and 48. | Baseline, Weeks 24 and 48 | 
| Percentage of Participants with Grade 3 and 4 Adverse Events (AEs), Serious Adverse Events (SAEs), and Participants Experiencing Premature Discontinuation due to AEs Through Week 48 | Percentage of participants with Grade 3 and 4 AEs will be assessed. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Percentage of participants who prematurely discontinued study due to AEs will also be analyzed. | Through Week 48 | 
| Percentage of Participants with Laboratory Abnormalities | Percentage of participants with laboratory abnormalities will be reported. | Up to Week 48 | 
| Number of Participant with Clinically Significant Change from Baseline in Laboratory Parameters | Number of participants with clinically significant change from baseline in laboratory parameters related to hematology, serum chemistry will be assessed. | Baseline up to Week 48 | 
| Emergence of Viral Resistance Through Weeks 24 and 48 | Resistance analysis will be determined using genotypic analysis at the time of virological failure (that is, 2 consecutive plasma HIV-1 RNA levels greater than or equal to [>=] 400 copies/mL through Weeks 24 and 48 of study treatment). | Through Weeks 24 and 48 | 
| Percentage of Participant with Treatment Adherence (95%) Based on Tablet Count up to Weeks 24 and 48 | Percentage of adherent participants as measure of treatment compliance will be assessed by tablet count. | Up to Weeks 24 and 48 |
