Patient-Reported Outcomes After a Switch to a Single-Tablet Regimen of Rilpivirine, Emtricitabine, and Tenofovir DF in HIV-1-Positive, Virologically Suppressed Individuals: Additional Findings From a Randomized, Open-Label, 48-Week Trial
Bibliographic record
Abstract
BACKGROUND: Patient-reported outcomes (PROs) can provide important information about treatment tolerability in HIV-1-infected patients. OBJECTIVE: The aim of this study was to evaluate PROs following switching from a boosted protease inhibitor-based regimen to the single-tablet regimen (STR) of rilpivirine/emtricitabine/tenofovir disoproxil fumarate (RPV/FTC/TDF) in the 48-week open-label Switching Boosted PI to Rilpivirine in Combination with Truvada as a Single-Tablet Regimen (SPIRIT) trial. METHODS: In the open-label SPIRIT trial, patients were randomized to receive an STR of RPV/FTC/TDF (n = 317) for 48 weeks or stay on their baseline regimen of a ritonavir-boosted protease inhibitor and two nucleoside/nucleotide analog reverse transcriptase inhibitors (PI + RTV + 2NRTIs, n = 159) for 24 weeks before switching to RPV/FTC/TDF for another 24 weeks. PRO assessments included the HIV Treatment Satisfaction Questionnaire (TSQ) and the HIV Symptom Index Questionnaire (SIQ). RESULTS: At week 24, the mean HIV TSQ improvement from baseline was significantly greater in the RPV/FTC/TDF group than the PI + RTV + 2NRTIs group (p < 0.001). On the HIV SIQ, the percentage of patients reporting a shift from 'symptom' to 'no symptom' was significantly greater with RPV/FTC/TDF treatment compared with PI + RTV + 2NRTIs for all items (all p ≤ 0.01), with total within-group occurrence of 13/20 symptoms significantly decreasing from baseline for RPV/FTC/TDF patients. In the delayed switch group, significantly fewer patients reported diarrhea and sleep problems at week 48 vs. week 24. CONCLUSIONS: These data suggest that switching to the STR RPV/FTC/TDF from a PI-based multi-pill regimen is associated with greater patient-reported treatment satisfaction and improved tolerability in HIV-1-infected, virologically suppressed individuals.

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.
