Change From Baseline in Pre-specified Treatment Symptoms Using the Symptom Distress Module at Weeks 4, 24 and 48-Early Switch Phase

Symptom Distress Module, also called the HIV Symptom Index or Symptoms Impact Questionnaire, is a 20-item self-reported measure that addresses 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 participant. Symptom count is the sum of number of symptoms present and ranges from 0 (none) to 20 (all). Symptom bother score is based on score for each symptom present ranging from 1 (it doesn't bother me) to 4 (it bothers me a lot). Symptom bother score is unweighted sum of the bother item scores for each symptom. 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. Day 1 was considered as Baseline value.

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. Total score, lifestyle/ease score and General satisfaction/CS have been summarized. LOCF was used as primary method of analysis. Value obtained at Day 1 was considered as Baseline value. Change from Baseline was calculated as value at indicated time point minus Baseline value.

Time frame: At Week 4, Week 24 and Week 48

Change From Baseline Treatment Satisfaction Using HIV TSQ at Weeks 56, 76, 100 and 148 - DTG+RPV Group Through Early and Late Switch Phase

Time frame: At Week 56, Week 76, Week 100 and Week 148

Change From LS Baseline Treatment Satisfaction Using HIV TSQ at Weeks 56, 76, 100 and 148-CAR Group Through Late Switch Phase

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. Total score, lifestyle/ease score and General satisfaction/CS have been summarized. LOCF was used as primary method of analysis. Value obtained at Week 48 was considered as LS Baseline value. Change from LS Baseline was calculated as value at indicated time point minus LS Baseline value.

Time frame: At Week 56, Week 76, Week 100 and Week 148

Number of Participants With Observed Genotypic Resistance for Participants Meeting Virologic Withdrawal Criteria by Baseline Third Agent Treatment Class-DTG+RPV Group Through Continuation Phase

For all participants who met virologic withdrawal criteria, plasma samples with HIV-1 RNA level \>=200 c/mL were analyzed in an attempt to obtain genotype data on as many samples as possible. Samples for drug resistance testing (genotypic) were collected at Day 1. Number of participants with genotypic resistance to DTG or RPV for those meeting virologic withdrawal criteria in subgroups, stratified based on baseline third agent treatment class (NNRTI, INI, PI) were summarized.

Time frame: Up to Week 411

Number of Participants With Observed Phenotypic Resistance for Participants Meeting Virologic Withdrawal Criteria by Baseline Third Agent Treatment Class-DTG+RPV Group Through Continuation Phase

For all participants who met virologic withdrawal criteria, plasma samples with HIV-1 RNA level \>=200 c/mL were analyzed in an attempt to obtain phenotype data on as many samples as possible. Samples for drug resistance testing (phenotypic) were collected at Day 1. Number of participants with phenotypic resistance to DTG or RPV for those meeting virologic withdrawal criteria in subgroups, stratified based on baseline third agent treatment class (NNRTI, INI, PI) were summarized.

Time frame: Up to Week 411

Number of Participants With Observed Genotypic Resistance for Participants Meeting Virologic Withdrawal Criteria by Baseline Third Agent Treatment Class- CAR Group Through Continuation Phase

For all participants who meet virologic withdrawal criteria, plasma samples with HIV-1 RNA level \>=200 c/mL were analyzed in an attempt to obtain genotype data on as many samples as possible. Number of participants with genotypic resistance to CAR for those meeting virologic withdrawal criteria in subgroups, stratified based on baseline third agent treatment class (INI) were summarized.

Time frame: Week 52 to Week 411

Number of Participants With Observed Phenotypic Resistance for Participants Meeting Virologic Withdrawal Criteria by Baseline Third Agent Treatment Class- CAR Group Through Continuation Phase

For all participants who meet virologic withdrawal criteria, plasma samples with HIV-1 RNA level \>=200 c/mL were analyzed in an attempt to obtain phenotype data on as many samples as possible. Number of participants with phenotypic resistance to CAR for those meeting virologic withdrawal criteria in subgroups, stratified based on baseline third agent treatment class (INI) were summarized.

Time frame: Week 52 to Week 411

Number of Participants With Genotypic Resistance-DTG+RPV Group Through Continuation Phase

Plasma samples were collected for participants meeting the CVW criteria (previous plasma HIV-1 RNA \>=50 c/mL and current plasma HIV-1 RNA \>= 200 c/mL) to evaluate any potential genotypic evolution of resistance. Genotypic resistance data for the following drugs was presented: DTG, EVG, RAL, DLV, EFV, ETR, NVP, RPV, 3TC, ABC, FTC, TDF, ZDV, d4T, ddI, ATV/r, DRV/r, FPV/r, IDV/r, LPV/r, NFV, RTV, SQV/r, TPV/r.

Time frame: Up to Week 411
