You may be eligible if
Participant must be able to understand and comply with protocol requirements, instructions, and restrictions;
Participant must be likely to complete the study as planned;
Participant must be considered an appropriate candidate for participation in an investigative clinical trial with medication (example no active substance abuse, acute major organ disease, or planned long-term work assignments out of the country).
Aged 18 years or older (or older where required by local regulatory agencies), at the time of signing the informed consent.
HIV-1 infected men or women.
Documented evidence of at least two plasma HIV-1 RNA measurements \<50 c/mL in the 12 months prior to Screening: one within the 6 to 12 month window, and one within 6 months prior to Screening.
Plasma HIV-1 RNA \<50 c/mL at Screening.
Must be on uninterrupted ART for at least 6 months prior to screening. Only the following regimens are allowed:
* Participant on a TAF-based regimen for at least 6 months as the initial regimen, or
* Participants who switched from a tenofovir disoproxil fumarate (TDF) first-regimen TAF, without any changes to the other drugs in their regimen, and have been on the TAF-based regimen for at least 3 months immediately prior to Screening i.e., the only switch made is from TDF to TAF. This switch must have occurred due to tolerability/safety, access to medications, or convenience/simplification, and must NOT have been done for suspected or established treatment failure. A switch from a PI boosted with ritonavir to the same PI boosted with cobicistat is allowed (and vice versa).
A female participant is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin \[hCG\] test at screen and a negative urine hCG test at randomization \[a local serum hCG test at Randomization is allowed if it can be done, and results obtained, within 24 hours prior to randomization\]), not lactating, and at least one of the following conditions applies:
a. Non-reproductive potential defined as:
Pre-menopausal females with one of the following:
* Documented tubal ligation
* Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion
* Hysterectomy
* Documented bilateral oophorectomy
Post-menopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone \[FSH\] and estradiol levels consistent with menopause \[refer to laboratory reference ranges for confirmatory levels\]). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.
b. Reproductive potential and agrees to follow one of the options listed in the Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) from 30 days prior to the first dose of study medication and for at least 2 weeks after the last dose of study medication.
The investigator is responsible for ensuring that participants understand how to properly use these methods of contraception. All participants participating in the study should be counseled on safer sexual practices including the use and benefit/risk of effective barrier methods (e.g., male condom) and on the risk of HIV transmission to an uninfected partner.
Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the consent form and the protocol. Eligible participants or their legal guardians must sign a written informed consent form before any protocol-specified assessments are conducted.
Participants enrolled in France must be affiliated to, or a beneficiary of, a social security category.
You may not be if
Women who are breastfeeding or plan to become pregnant or breastfeed during the study.
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.
Participants 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: participants positive for HBsAg are excluded; participants negative for anti-HBs but positive for anti-HBc (negative HBsAg status) and positive for HBV DNA are excluded.
Anticipated need for any hepatitis C virus (HCV) therapy during the first 48 weeks of the study, or anticipated need 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). Participants 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.
Participants 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, must be provided to ViiV after screening and before randomization for review by ViiV Virology.
Any verified Grade 4 laboratory abnormality.
Alanine aminotransferase (ALT) \>=5 times (\*) the upper limit of normal (ULN) or ALT \>=3 \* ULN and bilirubin \>=1.5 \* ULN (with \>35 percent \[%\] direct bilirubin).
Creatinine clearance of \<50 milliliter (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.
Participants 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
