Efficacy, safety, and patient satisfaction with oral semaglutide: first single-centre clinical experience.

Abstract

To explore the effects of oral semaglutide on glycaemic parameters, body weight, and satisfaction in the first recipient patients with type 2 diabetes mellitus in Slovenia, in a real-world clinical practice setting. The first consecutive adult patients with type 2 diabetes who were eligible for oral semaglutide treatment were included in this prospective, open-label interventional study. Patients received increasing doses of oral semaglutide and were evaluated at inclusion, at 1 month, then 3-5 months after starting treatment. Fasting blood glucose, glycosylated haemoglobin (HbA1c), body weight, patient satisfaction with oral semaglutide treatment (using the validated Treatment Satisfaction Questionnaire for Medication), and adverse effects, were analysed. Statistical analyses were performed using one-way analysis of variance, and, when significant interactions were found, Bonferroni post-hoc test. A P-value <0.05 was considered statistically significant. Twenty patients (11 male: 9 female; mean age, 59.9 ± 1.5 years; mean diabetes duration, 8.5 ± 1.4 years) were included. Oral semaglutide (7 and 14 mg) significantly decreased HbA1c (from 9.4 ± 0.3% to 8.2 ± 0.2% and 7.8 ± 0.2%, respectively) and fasting plasma glucose (from 11.2 ± 0.5 mmol/L to 9.2 ± 0.7 mmol/L and 8.9 ± 0.4 mmol/L, respectively). Oral semaglutide (14 mg) significantly decreased body weight (from 100.9 ± 2.7 kg to 92.7 ± 2.4 kg). Patients reported that treatment was easy to use and expressed high global satisfaction. Mild and transient, mostly gastrointestinal, adverse effects were reported in 10 patients. Oral semaglutide, the first oral glucagon-like peptide 1 receptor agonist, was effective and safe, and associated with high patient satisfaction, in its first recipients in Slovenia. The results are important for daily clinical practice involving patients with type 2 diabetes, however, due to the small study population, lack of placebo control, and short exposure to oral semaglutide, the effectiveness of oral semaglutide in clinical practice requires further investigation.
