930-P: Efficacy of Oral Semaglutide According to Race: An Exploratory Subgroup Analysis of the PIONEER Trial Program
Bibliographic record
Abstract
The global PIONEER program investigated the efficacy and safety of oral semaglutide, a glucagon-like peptide-1 receptor agonist. Patients with type 2 diabetes were randomized to once-daily oral semaglutide (3, 7 or 14 mg, or flexibly dosed [flex]), placebo, or active comparator (empagliflozin 25 mg, sitagliptin 100 mg or liraglutide 1.8 mg). This exploratory subgroup analysis evaluated the effect of race on glycated hemoglobin (HbA1c) and body weight (BW) reductions at the end of treatment (week 26, 52 or 78). Data were analyzed from PIONEER 1-5, 7 and 8 by race (White, Asian, Black/African American). Baseline characteristics were generally similar across subgroups except for BW, which was lower in Asian patients. Generally, greater HbA1c reductions were observed with oral semaglutide 14 mg/flex vs. comparators across subgroups (Table). In PIONEER 1, 4 and 8, there was a significant interaction between treatment and race, with greater HbA1c reductions and estimated treatment differences in Asian patients than in other subgroups (Table). Overall, BW reductions were greater for oral semaglutide vs. comparators, regardless of subgroup and without significant interactions between treatment and race. Our findings in this exploratory subgroup analysis suggest that, in some PIONEER trials, Asian patients achieve greater HbA1c reductions than other race groups when treated with oral semaglutide.

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.
