Remission Evaluation of a Metabolic Intervention in Type 2 Diabetes With Sitagliptin (REMIT-Sita)

15. marts 2022 opdateret af: Population Health Research Institute

An Open-label, Randomized, Parallel Design Trial to Compare the Efficacy of a Sitagliptin-based Metabolic Intervention Versus Standard Diabetes Therapy in Inducing Remission of Type 2 Diabetes

The purpose of the study is to determine whether in patients with early type 2 diabetes,a short-term intensive metabolic intervention comprising of sitagliptin, metformin, basal insulin glargine and lifestyle approaches will be superior to standard diabetes therapy in achieving sustained diabetes remission.

Detaljeret beskrivelse

This is a multicentre, open-label, randomized controlled trial in 100 patients with recently-diagnosed T2DM. Participants will be randomized to 2 treatment groups: (a) a 12-week course of treatment with sitagliptin, metformin, insulin glargine and lifestyle therapy, or (b) standard diabetes therapy, and followed for a total of 64 weeks (1 year and 3 months). In all participants with HbA1C < 7.3% at the 12 week visit, glucose-lowering medications will be discontinued and participants will be encouraged to continue with lifestyle modifications and regular glucose monitoring. Participants with HbA1C ≥ 7.3% at this visit or who meet criteria for hyperglycemic relapse after stopping drugs will receive standard glycemic management as informed by the current Canadian Diabetes Association clinical practice guidelines
