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

March 15, 2022 updated by: 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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
