Rapid Test and Treat Dolutegravir Plus Lamivudine Study in Newly Diagnosed Human Immunodeficiency Virus (HIV)-1 Infected Adults

Early initiation of antiretroviral therapy (ART) reduces morbidity and mortality for individuals infected with HIV. Suppressing viral replication with ART also reduces the potential for transmission of HIV. Hence, ART is recommended for all persons with HIV viremia regardless of cluster of differentiation 4 (CD4) count. This is an open-label single arm which will evaluate the feasibility, efficacy and safety using a fixed dose combination (FDC) of Dolutegravir (DTG) plus Lamivudine (3TC) as a first line regimen of a rapid Test and Treat model of care over 48 weeks. Participants with new and confirmed diagnosed HIV-1 who are willing to start study treatment immediately following diagnosis will receive 50 milligram (mg) DTG + 300 (mg) 3TC FDC as first line therapy without waiting for screening laboratory results, at the Screening/Day 1 Visit. The total duration for the study will be 52 weeks and 4 weeks of follow up period if required. This study will be conducted in United States (US) with approximately 120 participants.


Eligibility Criteria:
Inclusion Criteria:

* Eligible participants must be able to understand and comply with protocol requirements, instructions, and restrictions.
* Eligible participants must be likely to complete the study as planned.
* Eligible participants must be considered appropriate candidates for participation in an investigative clinical trial with oral medication (e.g. no active problematic substance abuse, acute major organ disease, or potential long-term work assignments out of the country).
* Participant must be more than or equal to 18 at the time of signing the informed consent.
* Participants must have a new and confirmed diagnosis of HIV-1 infection and are willing to initiate ART immediately (or, for those participants referred from another site, within 14 days of initial diagnosis at the external clinic/testing center).
* Participant must have an initial positive rapid HIV test and participant has a second positive confirmatory rapid HIV test, using a test kit from a different manufacturer than the first test or participant has been identified as HIV-1 infected using an FDA-approved 4th generation assay antigen/antibody combination immunoassay or 3rd generation immunoassay that detects and differentiates HIV-1 and HIV-2 antibodies; participant has a confirmatory HIV western blot or an HIV-1 RNA or participant has a positive FDA-approved 4th generation assay and a positive 3rd generation immunoassay that detects and differentiates HIV-1 and HIV-2 antibodies.
* Antiretroviral-naïve. Participants who received HIV post-exposure prophylaxis (PEP) or pre-exposure prophylaxis (PrEP) in the past are allowed as long as the last PEP/PrEP dose was more than 6 months from HIV diagnosis or there is documented HIV seronegativity at least 2 months after the last prophylactic dose and prior to the date of HIV diagnosis.
* Male and/or female participants.
* Participants who are female at birth are eligible to participate if at least one of the following conditions applies: Not pregnant \[as confirmed by a negative urine human chorionic gonadotropin (hCG) test at Screening/Day 1.
* Pregnant and post the first trimester (the physician and patient should decide whether enrolling in this study is in the participants best interest during the consent process)
* Not a participant of childbearing potential (POCBP) or a POCBP agrees to follow the contraceptive guidance, is currently taking hormonal contraceptives and continues for at least 2 weeks after the last dose of study medication. Participants who are female at birth and who are in the following categories are not considered POCBP, premenarchal, premenopausal female with one of the following: documented hysterectomy, documented bilateral salpingectomy, documented bilateral oophorectomy or postmenopausal, a postmenopausal state is defined as no menses for 12 months without an alternative medical cause; a high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in participants who are female at birth and not using hormonal contraception or hormonal replacement therapy (HRT); participants who are female at birth on HRT and whose menopausal status is in doubt will be required to use one of the non-hormonal highly effective contraception methods if they wish to continue their HRT during the study.
* Participants who are capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

Exclusion Criteria:

* Participants who are breastfeeding, plan to become pregnant or breastfeed during the study.
* Participants who are in their first trimester of pregnancy.
* HIV-1 drug resistance genotype test results are known prior to Screening/Day 1.
* Any evidence of an active Centers for Disease Control and Prevention (CDC) Stage 3 disease except for esophageal candidiasis and cutaneous Kaposi's sarcoma not requiring systemic therapy.
* Participants with known or suspected Hepatitis B infection.
* Participants with known or suspected severe hepatic impairment or unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, or persistent jaundice), cirrhosis, known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
* Participants with known moderate to severe renal impairment (creatinine clearance less than 30ml/minute per 1.73 square meter);
* Participant with ongoing malignancy other than basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical, anal or penile intraepithelial neoplasia; other localized malignancies require agreement between the investigator and the Study Medical Monitor for inclusion of the participant.
* Participants who in the investigator's judgment, poses a significant suicidality risk.
* Participants with any pre-existing physical or mental condition which, in the opinion of the Investigator, may interfere with the participant's ability to comply with the dosing schedule and/or protocol evaluations or which may compromise the safety of the participant.
* Participants with substance abuse disorders or social restraints that the Investigator considers to be possible deterrents to successful initiation of ART.
* Participants with history or presence of allergy or intolerance to the study drugs or their components.
* Participants with treatment with any of the following agents within 28 days of the first dose of study treatment, radiation therapy, cytotoxic chemotherapeutic agents, any systemic immune suppressant.
* Participants receiving any prohibited medication and who are unwilling or unable to switch to an alternate medication.
* 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 study treatment.
