Percent Change From Baseline in Total Hip Bone Mineral Density (BMD) at Week 48Primary· Baseline (Day 1) and Week 48
Percent change in BMD (expressed as areal density in grams per centimeter square \[g/cm\^2\]) as specified by dual energy X-ray absorptiometry (DEXA) scans of the left 'total hip' which included the femoral neck, trochanter and inter-trochanter areas was assessed by areal density at Baseline and Week 48. The estimated value in the statistical analysis is this difference and the upper and lower limit values shown are the 95% confidence intervals. Baseline was considered as Day 1 and percent change from Baseline was calculated as Value at Week 48 minus Baseline value divided by Baseline value mu

Change From Baseline in Total Hip and Lumbar Spine BMD at Week 48 Assessed by T-score and Z-scoreSecondary· Baseline (Day 1) and Week 48
Total hip and lumbar spine BMD was assessed by T-scores and Z-scores. Day 1 was considered as Baseline. Change from Baseline was calculated as the value at Week 48 minus Baseline. DEXA scans of the left 'total hip' (femoral neck, hip, inter-trochanter areas, trochanter) and 'lumbar spine' (lumbar vertebral column) were performed. T-score is the number of standard deviations above or below the mean BMD of a 30-year-old participant of the same sex. Caucasian reference values were used for all participants to calculate T-scores. T-score values \> -1.0 are considered normal, T-score values \<= -1.

Percent Change From Baseline in Total Hip and Lumbar Spine BMD at Week 48 by Baseline Third AgentSecondary· Baseline (Day 1) and Week 48
Total hip and lumbar spine BMD (expressed as areal density in g/cm\^2) assessed by third agent class (INSTI, NNRTI, PI) at indicated time points. Percent change from Baseline was calculated as value at Week 48 minus Baseline value divided by Baseline value multiplied by 100. Value at Day 1 was considered as Baseline. An ANCOVA model adjusted for Baseline BMD values was used to compare the difference in percent change from Baseline to Week 48 in total hip BMD or in lumbar spine BMD between the DTG+RPV and CAR arms by third agent class: INSTI, NNRTI or PI.

Sponsor's own description
The purpose of this study is to evaluate any change from baseline in bone mineral density (BMD) in subjects following the switch from a triple antiretroviral therapy (ART) regimen containing Tenofovir disoproxil fumarate (TDF) to the nucleoside reverse transcriptase inhibitor (NRTI) - sparing two - drug regimen of dolutegravir (DTG) + rilpivirine (RPV) in subjects participating in the parent studies 201636 and 201637 (SWORD-1 and SWORD-2).
This open-label, parallel group, study is a sub-study which will recruit subjects who are receiving ART regimens which include TDF at the time of randomization to receive treatment in one of two identical parent studies 201636 and 201637 (SWORD-1 and SWORD-2). These are Phase III, randomised, open-label, multicentre, parallel-group, non-inferiority studies evaluating the efficacy, safety, and tolerability of switching to DTG plus RPV from current integrase inhibitor (INI)-, non NNRTI-, or protease inhibitor (PI)-based antiretroviral regimen in HIV-1-infected adults who are virologically suppressed, having HIV-1 ribonucleic acid (RNA) levels \<50 copies per millilitre (c/mL). Randomisation in the parent studies will be stratified by baseline third agent class (INI, NNRTI, or PI), age group (\< or =\>50 years old) and participation in this Dual energy X-ray absorptiometry (DEXA) sub-study, therefore there will also be balance across the treatment arms in this sub-study both overall and with respect to baseline third agent class and age at entry.
The study population will include approximately 75 evaluable subjects recruited from the Early Switch DTG + RPV treatment group of the parent studies 201636 and 201637, and approximately 75 evaluable subjects from the Late Switch group who continue their current antiretroviral therapy (CAR) through to Week 52 across both the 201636 and 201637 (SWORD-1 and SWORD-2) studies. Subjects participating in study 202094 will have DEXA scans performed at Day 1 and at study Weeks 48, 100 and 148 in parallel with the corresponding scheduled visits in the parent studies.
