Switching to a Fixed Dose Combination of Bictegravir/Emtricitabine/Tenofovir Alafenamide (B/F/TAF) in HIV-1 Infected Marginalized Populations Who Are Virologically Suppressed

October 17, 2019 updated by: Vancouver Infectious Diseases Centre
In an effort to engage more HIV-infected PWUD into care, and ensure treatment adherence and efficacy, simplification of older, multi-tablet regimens is required. Newer, more potent molecules can also overcome resistant that has persisted with previous regimens, while simultaneously providing a high barrier to resistance. The co-formulation of B/F/TAF is a viable switch-option for patients who have experienced lower adherence with previous regimens due to high pill burden, or for those requiring a more potent regimen due to emergent resistances. The formal evaluation of B/F/TAF in this context will allow us to optimize care for HIV-infected PWUD.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
