About this study
Official title: A Phase 3b, Randomized, Open-label Study of the Antiviral Activity and Safety of Dolutegravir Compared to Lopinavir/Ritonavir Both Administered With Dual Nucleoside Reverse Transcriptase Inhibitor Therapy in HIV-1 Infected Adult Subjects With Treatment Failure on First Line Therapy
For treatment of human immunodeficiency virus type 1(HIV-1), publicly funded programmes tend to follow World Health Organization (WHO) guidelines to use a non-nucleoside reverse transcriptase inhibitor (NNRTI) combined with two nucleoside reverse transcriptase inhibitors (NRTIs) for first-line antiretroviral therapy (ART); however, there is a need for further data on the best treatment options for people with HIV-1 who have virological failure with this first-line regimen. The number of patients failing on their first-line regimen is increasing thereby requiring a switch to second-line treatment to reduce accumulation of drug-resistance mutations, disease progression, HIV transmission, and death. WHO guidelines recommend second-line antiretroviral therapy for adults consisting of two NRTIs + a ritonavir-boosted protease inhibitor (PI); atazanavir (ATV) plus ritonavir (RTV) or lopinavir (LPV)/RTV are the preferred boosted PI options. This study is conducted to demonstrate non-inferior antiviral activity at 48 weeks of a dolutegravir (DTG) containing regimen compared to a WHO-recommended standard of care regimen for second line treatment, LPV/RTV + two NRTIs, in HIV-1 infected patients failing first line therapy. This study comprises of a Screening Phase (approximately 28 to 42 days), a Randomized Phase (Day 1 to Week 48 plus a 4-week treatment extension), and a Continuation Phase. Approximately 612 subjects will be randomized 1:1 to receive DTG 50 milligram (mg) once daily or LPV/RTV (800/200 mg once daily or 400/100 mg twice daily, in accordance with investigator decision and local label), each added to an investigator selected background regimen of two NRTIs at least one of which needs to be fully active based on viral resistance testing at Screening. Subjects randomized to the LPV/RTV arm will either (i) continue receiving LPV/RTV and complete the study after the 4-week treatment extension at Week 52, or (ii) switch to the DTG arm prior to study completion at Week 52 and continue to have access to DTG in the Continuation Phase. Subjects randomized to receive DTG who successfully complete 52 weeks of treatment and subjects originally randomized to receive LPV/RTV but switched to DTG prior to Week 52 will continue to have access to DTG until it is either locally approved and commercial supplies are available to patients or the patient no longer derives clinical benefit, or the patient meets a protocol-defined reason for discontinuation.

Participants were graded using the Division of AIDS Table for Grading Severity of Adult and Pediatric Adverse Events. Grade 1=mild; grade 2=moderate; grade 3=severe; grade 4=potentially life-threatening. Higher the grade, more severe the symptoms.
Measured: Week 24 and Week 48
Change From Baseline in Gastrointestinal Symptom Rating Scale (GSRS) Score
The GSRS is a disease-specific instrument of 15 items combined into five symptom clusters depicting Reflux, Abdominal pain, Indigestion, Diarrhea and Constipation. The scale ranges from 1= no discomfort to 7= very severe discomfort for each symptom cluster. Higher scores show greater severity of symptoms. Baseline was defined as the latest pre-dose assessment value. Change from Baseline was calculated as post-Baseline visit values minus Baseline value. The analysis was performed using Last Observation Carried Forward (LOCF) dataset. In the LOCF dataset, missing values were carried forward from the previous, non-missing available on-treatment assessment.
Measured: Baseline (Day 1, Pre-dose), Week 4, Week 24, Week 48
Change From Baseline in Treatment Satisfaction, Using the HIV-Treatment Satisfaction Questionnaire (HIVTSQ) Score
The HIVTSQ is a self-reported scales that measure overall satisfaction with treatment. The score ranges from 0-10. The higher the score, the greater the improvement in treatment satisfaction as compared to the past few weeks. A smaller score represents a decline in treatment satisfaction compared to the past few weeks. Baseline was defined as the latest pre-dose assessment value. Change from Baseline was calculated as post-Baseline visit values minus Baseline value. The analysis was performed using LOCF dataset. In the LOCF dataset, missing values were carried forward from the previous, non-missing available on-treatment assessment.
Measured: Baseline (Day 1, Pre-dose), Week 4, Week 24, Week 48
Number of Participants Showing Adherence With Treatment, Using the Morisky 8-Item Medication Adherence Scale (MMAS-8)
Treatment compliance was evaluated through MMAS-8. It is an eight-item self-reported measure of medication-taking behavior. The score ranges from 0-8 where scores of 8 indicate high or near perfect adherence, and scores of less than 6 indicate poor or inadequate adherence on the MMAS-8 scale. Number of participants showing low, medium and high adherence to treatment are presented. Low adherence is a score 0-5.75, medium adherence is a score of 6-7.75 and high adherence is a score of 8. The analysis was performed using LOCF dataset. In the LOCF dataset, missing values were carried forward from the previous, non-missing available on-treatment assessment.
Measured: Baseline (Day 1, Pre-dose), Week 4, Week 24 and Week 48

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
For treatment of human immunodeficiency virus type 1(HIV-1), publicly funded programmes tend to follow World Health Organization (WHO) guidelines to use a non-nucleoside reverse transcriptase inhibitor (NNRTI) combined with two nucleoside reverse transcriptase inhibitors (NRTIs) for first-line antiretroviral therapy (ART); however, there is a need for further data on the best treatment options for people with HIV-1 who have virological failure with this first-line regimen. The number of patients failing on their first-line regimen is increasing thereby requiring a switch to second-line treatment to reduce accumulation of drug-resistance mutations, disease progression, HIV transmission, and death. WHO guidelines recommend second-line antiretroviral therapy for adults consisting of two NRTIs + a ritonavir-boosted protease inhibitor (PI); atazanavir (ATV) plus ritonavir (RTV) or lopinavir (LPV)/RTV are the preferred boosted PI options. This study is conducted to demonstrate non-inferior antiviral activity at 48 weeks of a dolutegravir (DTG) containing regimen compared to a WHO-recommended standard of care regimen for second line treatment, LPV/RTV + two NRTIs, in HIV-1 infected patients failing first line therapy. This study comprises of a Screening Phase (approximately 28 to 42 days), a Randomized Phase (Day 1 to Week 48 plus a 4-week treatment extension), and a Continuation Phase. Approximately 612 subjects will be randomized 1:1 to receive DTG 50 milligram (mg) once daily or LPV/RTV (800/200 mg once daily or 400/100 mg twice daily, in accordance with investigator decision and local label), each added to an investigator selected background regimen of two NRTIs at least one of which needs to be fully active based on viral resistance testing at Screening. Subjects randomized to the LPV/RTV arm will either (i) continue receiving LPV/RTV and complete the study after the 4-week treatment extension at Week 52, or (ii) switch to the DTG arm prior to study completion at Week 52 and continue to have access to DTG in the Continuation Phase. Subjects randomized to receive DTG who successfully complete 52 weeks of treatment and subjects originally randomized to receive LPV/RTV but switched to DTG prior to Week 52 will continue to have access to DTG until it is either locally approved and commercial supplies are available to patients or the patient no longer derives clinical benefit, or the patient meets a protocol-defined reason for discontinuation.
