Efficacy and safety of B/F/TAF in treatment-naïve and virologically suppressed people with HIV ≥ 50 years of age: integrated analysis from six phase 3 clinical trials
Bibliographic record
Abstract
Abstract Introduction Older adults with HIV, particularly those ≥ 50 years of age, face unique health challenges due to a higher prevalence of comorbidities and polypharmacy, which can impact medication adherence and increase the risk of adverse events. We assessed the efficacy and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV (PWH) ≥ 50 years of age across treatment-naïve and virologically suppressed cohorts over a long-term follow-up. Methods This post hoc analysis included participants ≥ 50 and < 50 years of age from six phase 3 trials of B/F/TAF, comprising 2 treatment-naïve studies and 4 virologically suppressed studies. Outcomes were assessed through Week 240 for the treatment-naïve cohort and Week 48 for the virologically suppressed cohort. Key measures included virologic outcomes (HIV-1 RNA < 50 or ≥ 50 copies/mL), CD4 T-cell changes, adherence, metabolic and renal parameters, treatment-emergent adverse events, and treatment-emergent diabetes and hypertension. Results The treatment-naïve cohort included 96 participants ≥ 50 years of age and 538 participants < 50 years of age, while the virologically suppressed cohort included 450 participants ≥ 50 years of age and 640 participants < 50 years of age. By Week 240, virologic suppression was achieved in 98.5% of treatment-naïve participants ≥ 50 years of age and in 98.6% of those < 50 years of age, as determined using missing = excluded analysis. By Week 48, virologic failure was 0.9% versus 1.4% in participants ≥ 50 years of age versus < 50 years of age, respectively, and virologic suppression was maintained in 93.6% of virologically suppressed participants in both the ≥ 50 and < 50 years of age groups, as assessed using the US Food and Drug Administration snapshot algorithm. Across age groups, the treatment-naïve and virologically suppressed cohorts demonstrated comparable outcomes beyond viral load through Weeks 240 and 48, respectively, including CD4 T-cell changes, adherence rates of ≥ 95%, body weight, lipid profiles, renal function, bone health, treatment-emergent adverse events, and the incidence of treatment-emergent diabetes and hypertension. Conclusions These results highlight the durability, long-term efficacy, safety, and overall benefits of B/F/TAF in PWH ≥ 50 years of age.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
