Bictegravir Efficacy With 1st INSTI Generation Failure History (BEING)

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.
