Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Drugs - ABC/DTG/3TC Placebo
Treatment: Drugs - B/F/TAF Placebo

Experimental: Blinded Phase: B/F/TAF - B/F/TAF + ABC/DTG/3TC placebo for at least 48 weeks

Active comparator: Blinded Phase: ABC/DTG/3TC - ABC/DTG/3TC + B/F/TAF placebo for at least 48 weeks

Summary
Brief summary
The primary objective of this study is to evaluate the efficacy of switching from a regimen of dolutegravir (DTG) and abacavir/lamivudine (ABC/3TC) or a fixed dose combination (FDC) of abacavir/dolutegravir/lamivudine (ABC/DTG/3TC) to a FDC of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus continuing DTG and ABC/3TC as the FDC ABC/DTG/3TC in virologically suppressed Human Immunodeficiency Virus- 1 (HIV-1) infected adults.
