Oral Semaglutide Preserves Islet of Langerhans Structure and Cellular Integrity in a Type 2 Diabetes Mellitus Rat Model: Histological, Immunohistochemical, and Biochemical Study
Semaglutide · biorxiv-preprint · 2026 · Observational · Preclinical
Oral semaglutide may help preserve islet structure and function in type 2 diabetic rats, but further research is needed to confirm these effects in humans.
P < 0.05 for islet size, β-cell mass, and insulin immunoreactivity.

Substance-Level Disproportionate Reporting of Impaired Gastric Emptying for Five Glucagon-Like Peptide-1 Receptor Agonists: A Reproducible Signal-Detection Analysis of the FDA Adverse Event Reporting System
Semaglutide · biorxiv-preprint · 2026 · Observational
Semaglutide has the highest reported association with impaired gastric emptying among GLP-1 receptor agonists, but this study does not claim causation.
PRR 88.7, 95% CI 85.1–92.4; 3,052 of 82,911 reports

Class-Wide Disproportionate Reporting of Impaired Gastric Emptying Across Nine Glucagon-Like Peptide-1 Receptor Agonist Products: A Signal-Detection Analysis of the FDA Adverse Event Reporting System
Semaglutide · biorxiv-preprint · 2026 · Observational
Semaglutide-based products show the highest reporting ratios for impaired gastric emptying among GLP-1 receptor agonists, but further studies are needed to understand the clinical significance.
Ozempic PRR 109.1; Rybelsus 66.4

Weight Regain During Continued Incretin Therapy Is Associated With an Inflammatory Signature at Weight Nadir and Higher Cardiovascular Event Rates
Semaglutide · biorxiv-preprint · 2026 · Observational
Weight regain during semaglutide or tirzepatide treatment is linked to increased inflammation and higher cardiovascular event rates, highlighting the need for careful monitoring.
12.9 vs 9.6 per 1,000 person-years for nonfatal MACE during regained time vs maintained-loss time, adjusted RR: 1.43 (95% CI 1.22–1.67).

Multimodal Strategies for Obesity Management: Integration and Combination of GLP-1/GIP Therapies, Bariatric Endoscopy, and Metabolic Surgery: A Scoping Review
Semaglutide · biorxiv-preprint · 2026 · Observational
Multimodal strategies for obesity management, including GLP-1 therapies and surgical interventions, may lead to greater weight loss than single approaches, but the evidence is largely observational and requires further validation.
Not reported in abstract.

Real-World Insulin Deintensification and Discontinuation with GLP-1 Incretin Therapies Versus SGLT2 Inhibitors in Type 2 Diabetes
Semaglutide · biorxiv-preprint · 2026 · Observational
Semaglutide is associated with a higher rate of basal insulin discontinuation compared to SGLT2 inhibitors, while tirzepatide shows greater insulin dose reduction and glycemic improvement.
27.8% discontinued basal insulin with semaglutide vs 22.2% with SGLT2-i at 24 months, sHR 1.26, 95% CI 1.05–1.52, Gray P=0.013

Semaglutide Activates the Orexin/Hypocretin and Basal Forebrain Cholinergic Systems and Increases Acetylcholine Levels in the Hippocampus of Young and Aged Rats
Semaglutide · biorxiv-preprint · 2026 · Animal study · Preclinical
Semaglutide activates specific neuronal systems and increases acetylcholine in the rat hippocampus, suggesting a potential mechanism for cognitive effects.
Semaglutide acutely increases acetylcholine efflux in the ventral hippocampus of conscious and freely moving rats.
B

Glucagon-like peptide-1 receptor agonists and healthcare use in older adults with heart failure and obesity
Semaglutide · biorxiv-preprint · 2026 · Observational
Among older adults with heart failure and obesity, adding GLP-1 RA to standard therapy may reduce hospital admissions and medical costs, despite higher medication expenses.
Adjusted risk ratio for all-cause inpatient utilization was 0.89 (95% CI: 0.84 – 0.93) for HF therapy + GLP-1 RA vs HF therapy.
