A Registry-based Randomized Controlled Trial in Type 2 Diabetes With Cardiovascular Risk Factors (REMATCH)

Официальное название

Registry Based Randomized Controlled Trial of Multiple Combination Strategies of Intensive Glycemic Control to Reduce a Composite of Macrovascular and Microvascular Events in Type 2 Diabetes With Cardiovascular Risk Factors (REMATCH Study)

Обзор

Glycemic control is a mainstay of diabetes management to reduce the risk of microvascular complications and cardiovascular outcomes in people with type 2 diabetes (T2D). However, intensive control to near-normal glycated hemoglobin (HbA1c) yielded complex results in previous landmark trials. Potential risks of intensive glycemic control, such as hypoglycemia and weight gain, may partly contributed to the possible harms associated with this approach. Recent advances in diabetes management with development of newer antidiabetic drugs which minimize possible harms of intensive glycemic control as well as reduce cardiorenal risks enabled safer glycemic reduction. Thus, this randomized trial aims to evaluate the effects of near normalization of HbA1c with novel approaches on microvascular complications and cardiovascular outcomes in people with T2D.

Подробное описание

This is a multicenter, prospective, registry-based, randomized, open-label, active-comparator controlled trial involving 5,950 eligible participants with T2D, cardiovascular risk factors, and elevated HbA1c (≥7.0%). Participants will be randomly assigned to either intensive arm (targeting 6.0% of HbA1c) or standard arm (targeting 7.0% of HbA1c). The primary end point is the time to development of a composite of major adverse cardiovascular and diabetic microvascular events.

This study is designed as registry-based randomized clinical trial (RRCT), which adheres to the characteristics of both randomized clinical trial and registry-based prospective observational study. The participants will be randomly assigned into either intensive glycemic control arm or standard glycemic control arm, and the outcomes and variables will be recorded by multiple registries including hospital electronic medical records, nationwide health registry (the national health insurance service, NHIS), and Korean Statistical Information Service registry.
