Regimen Switch to Dolutegravir + Rilpivirine From Current Antiretroviral Regimen in Human Immunodeficiency Virus Type 1 Infected and Virologically Suppressed Adults (SWORD-2)

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to determine if virologically suppressed, human immunodeficiency virus type 1 (HIV-1) infected adults on an antiretroviral regimen (including 2 nucleoside reverse transcriptase inhibitors [NRTIs] plus a third agent) remain suppressed upon switching to a two-drug regimen with dolutegravir (DTG) + rilpivirine (RPV). The study will primarily assess the non-inferiority antiviral activity of switching to DTG + RPV once daily compared to continuation of current antiretroviral regimen (CAR) up to Week 48 with a switch visit for eligible subjects in the CAR group to initiate DTG + RPV therapy at Week 52. CAR will include 2 NRTIs plus 1 HIV-1 integrase inhibitor (INI), or 1 non-nucleoside reverse transcriptase inhibitor (NNRTI), or 1 protease inhibitor (PI). The study will include a 148-week open-label treatment phase, comprising of an Early Switch Phase (Day 1 to Week 52) and a Late Switch Phase (Week 52 to Week 148). The participants fulfilling the study eligibility criteria will participate in the Early Switch Phase where they will either switch from their CAR to DTG + RPV, or continue taking their CAR, until Week 52. At the end of Early Switch Phase, eligible participants will proceed to the Late Switch Phase where all participants in both DTG + RPV and CAR treatment groups will receive DTG + RPV therapy until Week 148. After Week 148, subjects may be eligible to continue to receive DTG +RPV in the Continuation Phase. The study is planned to be conducted in approximately 476 participants.

| Number of Participants With Observed Genotypic Resistance for Participants Meeting Virologic Withdrawal Criteria by Baseline Third Agent Treatment Class | For all participants who meet virologic withdrawal criteria, plasma samples with HIV-1 RNA level >=200 c/mL were to be analyzed in an attempt to obtain genotype data on as many samples as possible. Samples for drug resistance testing (genotypic) were to be collected at Day 1. Number of participants with genotypic resistance to CAR and to DTG or RPV for those meeting virologic withdrawal criteria in subgroups stratified based on Baseline third agent treatment class (INSTI, NNRTI, PI) were to be summarized. This outcome has not been analyzed as the number of participants was low (1 CVW per arm) and summaries by Baseline third agent were not provided. Therefore, data are not available for this outcome measure due to the insufficient number of participants with events. | Week 48 | 
| Number of Participants With Observed Phenotypic Resistance for Participants Meeting Virologic Withdrawal Criteria by Baseline Third Agent Treatment Class | For all participants who meet virologic withdrawal criteria, plasma samples with HIV-1 RNA level >=200 c/mL were to be analyzed in an attempt to obtain phenotype data on as many samples as possible. Samples for drug resistance testing (phenotypic) were to be collected at Day 1. Number of participants with phenotypic resistance to CAR and to DTG or RPV for those meeting virologic withdrawal criteria in subgroups stratified based on Baseline third agent treatment class (INSTI, NNRTI, PI) were to be summarized. This outcome was not analyzed as the number of participants was low (1 CVW per arm) and summaries by Baseline third agent were not provided. Therefore, data are not available for this outcome measure due to the insufficient number of participants with events. | Week 48 | 
| Change From Baseline in Fasting Lipids at Weeks 24 and 48 by Baseline Third Agent Treatment Class | Blood samples were collected at Baseline (Day 1), Weeks 24 and 48 to assess fasting lipids which included total cholesterol (CHO), LDL cholesterol, HDL cholesterol and triglycerides. Change from Baseline was calculated as value at indicated time point minus Baseline value. | Baseline (Day 1), Weeks 24 and 48 | 
| Change From Baseline in Pre-specified Treatment Symptoms Using the Symptom Distress Module at Weeks 4, 24 and 48-Early Switch Phase | The Symptom Distress Module, also called the HIV Symptom Index or Symptoms Impact Questionnaire, is a 20-item self-reported measure that addresses the presence and perceived distress linked to symptoms commonly associated with HIV or its treatment. Symptom count is based on which of the 20 symptoms were present in the participant. Symptom count is the sum of the number of symptoms present and ranges from 0 (none) to 20 (all). Symptom bother score is based on the score for each symptom present ranging from 1 (it doesn't bother me) to 4 (it bothers me a lot). Symptom bother score is the unweighted sum of the bother item scores for each symptom. The symptom bother score ranges from 0 (minimum bother score) to 80 (maximum bother score). Last observation carried forward (LOCF) was used as primary method of analysis. Change from Baseline was calculated as value at indicated time point minus Baseline value. | Baseline (Day 1), Weeks 4, 24 and 48 | 
| Change From Baseline in Pre-specified Treatment Symptoms Using the Symptom Distress Module at Weeks 56, 76, 100 and 148-DTG+RPV Early Switch Group Through Early and Late Switch Phase | The Symptom Distress Module, also called the HIV Symptom Index or Symptoms Impact Questionnaire, is a 20-item self-reported measure that addresses the presence and perceived distress linked to symptoms commonly associated with HIV or its treatment. Symptom count is based on which of the 20 symptoms were present in the participant. Symptom count is the sum of the number of symptoms present and ranges from 0 (none) to 20 (all). Symptom bother score is based on the score for each symptom present ranging from 1 (it doesn't bother me) to 4 (it bothers me a lot). Symptom bother score is the unweighted sum of the bother item scores for each symptom. The symptom bother score ranges from 0 (minimum bother score) to 80 (maximum bother score). LOCF was used as primary method of analysis. Change from Baseline was calculated as value at indicated time point minus Baseline value. | Baseline (Day 1), Weeks 56, 76, 100 and 148 |

| Change From Baseline Treatment Satisfaction Using the HIV Treatment Satisfaction Questionnaire (HIV TSQ) at Weeks 4, 24 and 48-Early Switch Phase | The HIV TSQ is a 10-item self-reported scale that measures overall satisfaction with treatment and by specific domains e.g., convenience, flexibility. Each item is scored 0 to 6 where a higher score indicates the greater improvement in the past few weeks. These items are summed up to produce a treatment satisfaction total score (0 to 60) and 2 subscales: general satisfaction/clinical and lifestyle/ease subscales (0 to 30). The HIV TSQ was administered as a paper questionnaire. Total score, lifestyle/ease score and General satisfaction/clinical sub-score (CS) have been summarized. LOCF was used as primary method of analysis. Change from Baseline was calculated as value at indicated time point minus Baseline value. | Baseline (Day 1), Weeks 4, 24 and 48 | 
| Change From Baseline Treatment Satisfaction Using the HIV TSQ at Weeks 56, 76, 100 and 148-DTG+RPV Early Switch Group Through Early and Late Switch Phase | The HIV TSQ is a 10-item self-reported scale that measures overall satisfaction with treatment and by specific domains e.g., convenience, flexibility. Each item is scored 0 (very dissatisfied, inconvenient) to 6 (very satisfied, convenient). The items are summed up to produce a treatment satisfaction total score (0 to 60) and 2 subscale scores: general satisfaction/clinical and lifestyle/ease subscales (0 to 30). Higher scores indicated greater treatment satisfaction as compared to the past few weeks. The HIV TSQ was administered as a paper questionnaire. Change from Baseline is calculated as the value at specified time point minus Baseline value. Total score, lifestyle/ease score and General satisfaction/clinical sub-score (CS) have been summarized. LOCF was used as primary method of analysis. | Baseline (Day 1), Weeks 56, 76, 100 and 148 |
