Bictegravir Efficacy With 1st INSTI Generation Failure History - BEING Study-IMEA 075

Retrospective observational study using Data that was Previously Collected This is a retrospective cohort study based on the secondary analysis of data from the Nadis database. The study population will consist of all Virologically Suppressed (VS), or Virologically Unsuppressed (VU) Experienced patients at the time of switching to B/F/TAF, who had previously experienced treatment failure with first-generation InSTI before switching to B/F/TAF, who started B/F/TAF between January 1, 2019 and December 31, 2022, who had previously signed a consent for the use of their data in the Nadis database, and who had completed at least one follow-up visit after the initiation of B/F/TAF. Data will be collected until December 31, 2024, to cover a minimum of 24 months of follow-up for each participant. The baseline visit will be the time of ART initiation for B/F/TAF.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Study Population

The study population will consist of all Virologically Suppressed (VS), or Virologically Unsuppressed (VU) Experienced patients at the time of switching to B/F/TAF, who had previously experienced treatment failure with first-generation InSTI before switching to B/F/TAF, who started B/F/TAF between January 1, 2019 and December 31, 2022, who had previously signed a consent for the use of their data in the Nadis database, and who had completed at least one follow-up visit after the initiation of B/F/TAF. Data will be collected until December 31, 2024, to cover a minimum of 24 months of follow-up for each participant. The baseline visit will be the time of ART initiation for B/F/TAF.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion of participants with HIV-1 RNA <50 copies/mL in Patient living with HIV(PLWH) with virologic failure (VF) and virologically unsuppressed (VU). Analyzed to the FDA snapshot
Time Frame: Week 48

Group#1: PLWH with a prior VF on RAL- or EVG-based regimens and virologically suppressed (VS) (defined as HIV plasma RNA <50 copies/mL) at the time of switching to B/F/TAF Group#2: PLWH with a prior VF on RAL- or EVG-based regimens and virologically unsuppressed (VU) (defined as a HIV plasma RNA ≥50 copies/mL) at the time of switching to B/F/TAF.
Week 48

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
