A Study to Evaluate the Efficacy, Safety, and Tolerability of Using an Oral Once-daily 2 Drug Regimen Compared to an Oral Once-daily 3 Drug Regimen for the Treatment of Human Immunodeficiency Virus (HIV)-1 in Adults Who Have Not Previously Taken Antiretroviral Therapy

A Phase 3b, Multi-center, Randomized, Parallel-group, Open-label, Non-inferiority Study Evaluating the Efficacy, Safety, and Tolerability of Oral Dolutegravir/Lamivudine Once-daily as a First-line Regimen Compared to Oral Bictegravir/Emtricitabine/Tenofovir Alafenamide Once Daily for Virologic Suppression and Maintenance in Antiretroviral Therapy Naive Adults Living With HIV

Inclusion criteria

Inclusion criteria: -Participants with age >=18 years (or older, if required by local regulations) at the time of obtaining informed consent. -An individual participant is eligible to participate if they are not pregnant (as confirmed by a negative serum human chorionic gonadotropin (hCG) test at Screening and a negative urine hCG test at Enrollment) and not lactating. -Antiretroviral-naive (no prior therapy with any antiretroviral agent following a diagnosis of HIV-1 infection) person living with HIV. -Participant (or participant's legally acceptable representative [LAR]) is capable of giving written informed consent. -Eligible participants or their LAR must sign a written Informed Consent Form before any protocol-specified assessments are conducted. Enrollment of participants who are unable to provide direct informed consent is optional and will be based on local legal/regulatory requirements and site feasibility to conduct protocol procedures.

Exclusion criteria

Exclusion criteria: 1. Individuals who are pregnant or breastfeeding or plan to become pregnant or breastfeed during the study. 2. Any evidence of a current Centers for Disease Control and Prevention (CDC) Stage 3 disease; with the exception of cutaneous Kaposi's sarcoma not requiring systemic therapy, and CD4+ count 35% direct bilirubin). 10. Participants determined by the Investigator to have a high risk of seizures, including participants with an unstable or poorly controlled seizure disorder. A participant with a prior history of seizure may be considered for enrolment if the Investigator believes the risk of seizure recurrence is low. All cases of prior seizure history should be discussed with the Medical Monitor prior to enrolment. 11. Participants who, in the investigator's judgment, pose a significant suicide risk. Participant's recent history of suicidal behavior and/or suicidal ideation should be considered when evaluating for suicide risk. 12. Signs and symptoms which, in the opinion of the Investigator, are suggestive of active COVID-19 (e.g., fever, cough) infection within 14 days prior to enrollment. 13. Evidence of Hepatitis B virus (HBV) infection based on the results of central lab testing at Screening for Hepatitis B surface antigen (HBsAg), Hepatitis B core antibody (HBcAb), Hepatitis B surface antibody (HBsAb) and HBV Deoxyribonucleic Acid (DNA) as follows: -Participants positive for HBsAg are excluded; -Participants negative for HBsAb and negative for HBsAg but positive for HBcAb may be excluded based on the following consideration: i. Exclude if HBV DNA is detected [either Upper Limit of Quantification (ULoQ) OR numerical value (ie, between LLoQ and ULoQ)] ii. Not excluded if HBV DNA is negative, not detected 14. Participants with HCV co-infection at Screening are eligible only if: i. liver enzymes meet entry criteria; and ii. HCV disease is not anticipated to require on-study treatment with any agent(s) that have potential adverse DDIs with the study interventions; and iii. HCV disease has undergone appropriate work-up and is not advanced and will not require treatment prior to th
