Brief Report: Efficacy and Safety of Switching to a Single-Tablet Regimen of Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide in HIV-1/Hepatitis B–Coinfected Adults
Bibliographic record
Abstract
Coformulated elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide (E/C/F/TAF) has high efficacy and improved renal and bone safety in multiple phase 3 trials; TAF single agent is being studied in 2 phase 3 trials in patients with chronic hepatitis B. We report the results of an open-label, noncomparative switch study evaluating the efficacy and safety of E/C/F/TAF in HIV/hepatitis B virus (HBV)-coinfected adults. At 48 weeks, 91.7% of the 72 participants maintained or achieved virologic suppression (HIV-1 RNA <50 copies/mL; HBV DNA <29 IU/mL). Seroconversion occurred in 2.9% of hepatitis B surface antigen-positive participants and in 3.3% of HBV e antigen-positive participants; 40% of those with abnormal alanine aminotransferase normalized. E/C/F/TAF was associated with improved renal function and reduced bone turnover. These data support the use of E/C/F/TAF in treating HIV/HBV coinfection.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
