Bibliographic record
Abstract
AIM: Glucagon-like peptide-1 receptor agonists improve glycaemic control: some are now available as oral and subcutaneous formulations, and some have indications for reducing cardiovascular risk. The expanded scope for these therapies warrants comprehensive safety evaluations. We report the safety/tolerability of subcutaneous and oral semaglutide from the SUSTAIN and PIONEER clinical trial programmes, respectively. MATERIALS AND METHODS: Adverse events (AEs) from 16 randomized placebo- or active-controlled phase IIIa trials in patients with type 2 diabetes (n = 11 159) including once-weekly subcutaneous semaglutide (n = 3150; SUSTAIN trials) or once-daily oral semaglutide (n = 4116; PIONEER trials) were analysed. Data pools were analysed for each programme, with separate analyses of cardiovascular outcomes trials (CVOTs; n = 6480). RESULTS: In the phase IIIa pools, gastrointestinal disorders were reported in 41.9%/39.1% of patients with subcutaneous/oral semaglutide, respectively (most prevalent during initiation/escalation) versus 22.0%/24.8% with comparators. Rates of kidney disorders, acute pancreatitis, malignant neoplasms, hypoglycaemia, diabetic retinopathy, heart failure and other cardiovascular events were similar for semaglutide versus comparators. Cholelithiasis incidence was higher with subcutaneous and oral semaglutide versus placebo. Diabetic retinopathy incidence was higher with subcutaneous semaglutide versus placebo in SUSTAIN 6. Small pulse rate increases occurred with both formulations; there was no increased rate of arrhythmias. Fatal AE incidence was similar between semaglutide and comparators. Versus placebo, CVOTs showed a reduced risk of major adverse cardiovascular events with subcutaneous semaglutide and non-inferiority criteria were met with oral semaglutide. CONCLUSIONS: The most common AEs with semaglutide were gastrointestinal disorders, which decreased with continued therapy. These comprehensive safety/tolerability data may better inform patient selection and guidance in care.

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.
