Eligibility criteria:
Key Inclusion Criteria:

Documented historical genotype report showing mutation M184V and/or M184I (mixtures are acceptable) in reverse transcriptase. Individuals must not have any primary integrase strand transfer inhibitor (INSTI) or primary protease inhibitor (PI) resistance mutations present on historical genotype; non-nucleoside reverse transcriptase inhibitor (NNRTI) mutations are allowed.

Proviral deoxyribonucleic acid (DNA) test must not have additional exclusion resistance mutations against PIs, NRTIs and INSTIs

Part 1: Historical genotype report must show mutation M184V and/or M184I in reverse transcriptase WITHOUT any other NRTI resistance mutation (including thymidine analogue-associated mutations [TAMs] [TAMs are: M41L, D67N, K70R, L210W, T215Y/F, and K219Q/E/N/R], K65R, K70E, T69 insertion, and Q151M mutation complex [A62V, V75I, F77L, F116Y, Q151M])
Part 2 (after the interim efficacy review): Historical genotype report must show M184V and/or M184I in reverse transcriptase WITH or WITHOUT 1 or 2 TAMs. Evidence of K65R, K70E, T69 insertion and/or Q151M mutation complex will not be eligible
Currently receiving an ARV regimen consisting of FTC/TDF or ABC/3TC in combination with one third ARV agent for ≥ 6 consecutive months preceding the screening visit
Documented plasma HIV-1 ribonucleic acid (RNA) levels < 50 copies/mL for ≥ 6 months preceding the screening visit
Plasma HIV-1 RNA levels < 50 copies/mL at screening visit
Estimated glomerular filtration rate (GFR) ≥ 30 mL/min according to the Cockcroft-Gault formula for creatinine clearance

A female individual is eligible to enter the study if it is confirmed that she is:

not pregnant
of non-childbearing potential
stopped menstruating for ≥ 12 months
of childbearing potential and agrees to utilize the protocol-specified method of contraception or be non-heterosexually active or practice sexual abstinence from screening throughout the duration of study treatment and for 30 days following discontinuation of study drugs

Male individuals must agree to use the protocol-specified method(s) of contraception during heterosexual intercourse or be non-heterosexually active, or practice sexual abstinence from screening throughout the study period and for 30 days following the last study drug dose

Male individuals must agree to refrain from sperm donation from first dose until at least 30 days after the last study drug dose

Key Exclusion Criteria:

Individuals will have no evidence of previous virologic failure on a PI/r or INSTI-based regimen (with or without resistance to either class of ARV). Individuals may have evidence of prior virologic failure on only an NNRTI plus 2 NRTI-based regimen
Individuals on a current PI/r-based regimen will have no evidence of previous use of any approved or experimental integrase strand transfer inhibitor (INSTI) (for any length of time)
Hepatitis C infection that would require therapy during the study
Hepatitis B surface antigen (HBsAg) positive
Individuals with clinical evidence of decompensated cirrhosis (eg, ascites, encephalopathy, variceal bleeding)
Have an implanted defibrillator or pacemaker
A history of malignancy within the past 5 years (prior to screening) or ongoing malignancy other than cutaneous Kaposi's sarcoma (KS), basal cell carcinoma, or resected, non invasive cutaneous squamous carcinoma. Individuals with cutaneous KS are eligible, but must not have received any systemic therapy for KS within 30 days of Day 1 and must not be anticipated to require systemic therapy during the study
Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Day 1

NOTE: Other protocol defined Inclusion/ Exclusion criteria may apply.
