Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical study is to learn how safe it is to switch to an oral therapy of Bictegravir/Emtricitabine/Tenofovir (B/F/TAF) from Cabotegravir + Rilpivirine (CAB+RPV) in participants living with virologically suppressed human immunodeficiency virus type 1 (HIV-1), meaning participants with HIV RNA levels below detectable levels.

The primary objective of this study is to assess the safety of switching to B/F/TAF in virologically suppressed participants unable/unwilling to continue on CAB+RPV intramuscular (IM) injections or wishing to switch to oral therapy through Week 12.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* People with human immunodeficiency virus type 1 (HIV-1) (PWH) or provider decision to switch off cabotegravir + rilpivirine (CAB+RPV) intramuscular (IM) injections due to intolerance, inconvenience, adverse events (AEs), or willing to switch to (and intention to remain on) daily bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF).
* Currently virologically suppressed (HIV-1 ribonucleic acid (RNA) \< 50 copies/mL) on CAB+RPV IM injections every 2 months.
* Currently on CAB+RPV IM injections every 2 months and received at least one dose of CAB+RPV IM injection; no missed CAB+RPV injections.
* Ability to receive B/F/TAF up to 7 days prior to the next scheduled dose of CAB+RPV.
* Documented plasma HIV-1 RNA \< 50 copies/mL during treatment for ≥ 6 months preceding the screening visit.
* No documented or suspected resistance to bictegravir, emtricitabine, or tenofovir.

Exclusion Criteria

* History of B/F/TAF intolerance.
* History of previous integrase strand-transfer inhibitor (INSTI) virologic failure including CAB+RPV.
* Requirement for ongoing therapy with any prohibited medications listed in local prescribing information for B/F/TAF starting within 30 days prior to screening until 30 days following the last dose of study drug.
* Have been treated within 3 months of study screening or expected to receive during the study immunosuppressant therapies or chemotherapeutic agents (eg, chronic (at least 4 weeks) systemic steroids, immunoglobulins, and other immune- or cytokine-based therapies)
* Need for oral antiretroviral therapy (ART) bridge or use of other antiretroviral (ARV) agents prior to starting B/F/TAF on Day 1
