Oral semaglutide, market under the brand name Rybelsus, represents a ement advancement in the management of type 2 diabetes. As the first glucagon -like peptide-1 (GLP-1) receptor agonist avavable in oral formulation, it offers patients an alternative to injektable terapies while mainating compable efficacy.

This is a randomized, double-bledd, placebo- controled trial enrolling about 9,600 patients. Results from SCOUL triale arequestated 2024-2025.
  • Pediatric studies to evaluate safety and efficacy in children (if applicd). A Phase 3 trial in estimates aged 10-17 with type 2 diabetes is ongoing.
  • Product- specic farmakovigilance to monitor for rare adverse evens such as pankreatis, diabetic retinopatiy complications, and sete gastrocentral events. A divated postautorization safety study (PASS) for diabetic retinopathy was requested by the EMA.

These studies are appliered and results are reported to regulators and made public. Thee EMA also applics periodic safety update reports (PSUR) every six months for the first two years, then annually.
