Effectiveness and safety of oral semaglutide for type 2 diabetes in Chinese patients, analyzed by starting health factors

AI simplified

Abstract

Oral semaglutide led to greater reductions in HbA1c and body weight in 1,474 Chinese participants with type 2 diabetes.

  • Greater reductions in HbA1c were noted in subgroups with higher baseline HbA1c levels.
  • Similar baseline characteristics were observed across subgroups in both PIONEER trials.
  • Most adverse events reported were gastrointestinal-related and classified as mild-to-moderate.
  • The findings may support the efficacy and safety of oral semaglutide in diverse subpopulations with type 2 diabetes.
