Brief Summary:

The aim of the study is to establish if human immunodeficiency virus type 1 (HIV-1) infected adult subjects with current virologic suppression on a ≥3-drug tenofovir alafenamide (TAF) based regimen (TBR) remain suppressed upon switching to a two-drug regimen of dolutegravir (DTG) 50 milligram (mg) + lamivudine (3TC) 300 mg. This study will also provide important information regarding the safety and subject satisfaction with this two-drug regimen. The primary objective of this trial is to demonstrate the non-inferior antiviral activity of switching to DTG + 3TC once daily compared to continuation of TBR over 48 weeks in HIV-1 infected, ART-experienced, virologically suppressed subjects. This study also will characterize the long-term antiviral activity, tolerability and safety of DTG + 3TC compared to TBR through Week 144 and characterize the long-term antiviral activity, tolerability and safety of DTG + 3TC through Week 200.

This will be a 200-week, Phase III, randomized, open-label, active-controlled, multicenter, parallel-group study. The study will include a screening phase (up to 28 days), a randomized early switch phase (Day 1 up to Week 148), a randomized late switch phase (Week 148 up to Week 200), and a continuation phase (post Week 200). Approximately 550 HIV-1 infected adults on stable TBR will be randomized 1:1 to switch to DTG + 3TC once daily for up to 200 weeks, or to continue their TBR for 148 weeks, at which time and if HIV-1 ribonucleic acid (RNA) <50 copies per milliliter (c/mL) at Week 144, these subjects will switch to DTG + 3TC up to Week 200.


Condition or disease Intervention/treatment Phase
HIV Infections Drug: DTG + 3TC Drug: TAF based regimen (TBR) Phase 2 Phase 3

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 750 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: This is a randomized study with parallel group assignment where subjects will be randomized into one of the two treatment groups. Subjects randomized to DTG + 3TC will receive DTG + 3TC up to Week 200. Subjects randomized to TBR will continue to take their current regimen up to Week 148, at which time and if HIV-1 RNA <50 c/mL at Week 144, these subjects will switch to DTG + 3TC up to Week 200. Randomization will be stratified by Baseline third agent class (protease inhibitor [PI], integrase inhibitor [INI], or non-nucleoside reverse transcriptase inhibitor [NNRTI]).
Masking: None (Open Label)
Masking Description: This will be an open-label study and therefore no blinding is required. The Sponsor team aims to remain blinded to subject assignment, and will instruct sites to refrain from mentioning assignment when sending in queries (as the sites/subjects will not be blinded). No summaries of the study data according to actual randomized treatment groups will be available to sponsor staff prior to the planned Week 24 preliminary analysis.

  • Any evidence of an active Centers for Disease Control and Prevention (CDC) Stage 3 disease, EXCEPT cutaneous Kaposi's sarcoma not requiring systemic therapy. Historical or current CD4 cell counts less than 200 cells/millimeter (mm)^3 are NOT exclusionary.
  • Subjects with severe hepatic impairment (Class C) as determined by Child-Pugh classification.
  • Unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, oesophageal or gastric varices, or persistent jaundice), cirrhosis, known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • Evidence of Hepatitis B virus (HBV) infection based on the results of testing at Screening for Hepatitis B surface antigen (HBsAg), Hepatitis B core antibody (anti-HBc), Hepatitis B surface antigen antibody (anti-HBs) and HBV deoxyribonucleic acid (DNA) as follows: subjects positive for HBsAg are excluded; subjects negative for anti-HBs but positive for anti-HBc (negative HBsAg status) and positive for HBV DNA are excluded.

Note: Subjects positive for anti-HBc (negative HBsAg status) and positive for anti-HBs (past and/or current evidence) are immune to HBV and are not excluded. Anti-HBc must be either total anti-HBc or anti-HBc immunoglobulin G (IgG), and NOT anti-HBc IgM.

  • Anticipated need for any hepatitis C virus (HCV) therapy during the first 48 weeks of the study, for HCV therapy based on interferon or for any drugs that have a potential for adverse drug-drug interactions with study treatment throughout the entire study period.
  • Untreated syphilis infection (positive rapid plasma reagin [RPR] at Screening without clear documentation of treatment). Subjects who are at least 7 days post completed treatment are eligible.
  • History or presence of allergy or intolerance to the study drugs or their components or drugs of their class.
  • Ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical, anal or penile intraepithelial neoplasia.
  • Subjects who in the investigator's judgment, poses a significant suicidality risk.
  • Treatment with an HIV-1 immunotherapeutic vaccine within 90 days of Screening.
  • Treatment with any of the following agents within 28 days of Screening: radiation therapy; cytotoxic chemotherapeutic agents; any systemic immune suppressant.
  • Exposure to an experimental drug or experimental vaccine within either 28 days, 5 half-lives of the test agent, or twice the duration of the biological effect of the test agent, whichever is longer, prior to the first dose of investigational product (IP).
  • Use of any regimen consisting of single or dual ART.
  • Any evidence of major nucleoside reverse transcriptase inhibitor (NRTI) mutation or presence of any major INSTI resistance-associated mutation in any available prior resistance genotype assay test result, if known.
  • Any verified Grade 4 laboratory abnormality.
  • Alanine aminotransferase (ALT) ≥5 times the upper limit of normal (ULN) or ALT ≥3 times ULN and bilirubin ≥1.5 times ULN (with >35% direct bilirubin).
  • Creatinine clearance of <50 mL/minute/1.73 meter^2 via Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) method.
  • Within the 6 to 12 month window prior to Screening and after confirmed suppression to <50 c/mL, any plasma HIV-1 RNA measurement >200 c/mL.
  • Within the 6 to 12 month window prior to Screening and after confirmed suppression to <50 c/mL, 2 or more plasma HIV-1 RNA measurements ≥50 c/mL.
  • Within 6 months prior to Screening and after confirmed suppression to <50 c/mL on current ART regimen, any plasma HIV-1 RNA measurement ≥50 c/mL.
  • Any drug holiday during the 6 months prior to Screening, except for brief periods (less than 1 month) where all ART was stopped due to tolerability and/or safety concerns.
  • Any history of switch to another regimen, defined as change of a single drug or multiple drugs simultaneously, due to virologic failure to therapy (defined as a confirmed plasma HIV-1 RNA ≥400 c/mL.
  • Subjects enrolled in France (or in other countries as required by local regulations or Ethics Committee/Institutional Review Board [IRB]) who:

    • Participated in any study using an investigational drug or vaccine during the previous 60 days or 5 half-lives, or twice the duration of the biological effect of the experimental drug or vaccine, whichever is longer, prior to screening for the study, or
    • Participate simultaneously in another clinical study.
