Summary
The study aims at evaluating the maintenance of virologic suppression of dolutegravir/lamivudine (DTG/3TC) fixed dose combination (FDC) at Week 48 post-switch from bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in participants living with Human Immunodeficiency Virus Type 1 (HIV-1) who are of at least 50 years of age and above.
Eligibility Criteria
Inclusion Criteria
- Participants living with HIV-1 with documented plasma HIV-1 RNA ]35 percentage [%] direct bilirubin).
- Participant has estimated creatine clearance <30 millilitres per minute (mL/min) per 1.73 square meter (m^2) using the refitted, race-neutral Chronic Kidney Disease Epidemiology Collaboration (CKD-EPIcr\_R) method.
