DIabetes GLycemic Assessment in Newly Confirmed Episodes (DI-GLANCE)

1. juli 2026 opdateret af: Nazarii Kobyliak

Evaluation of Continuous Glucose Monitoring Systems for Optimizing Glycemic Control in Patients With Newly Diagnosed Type 2 Diabetes: A Postmarketing Clinical Analysis

This is a prospective, open-label, randomized controlled trial involving 80 adult patients with newly diagnosed T2DM (diagnosed within the last 3 months) recruited at the Bogomolets National Medical University. Participants may be lifestyle-controlled or receiving stable non-insulin anti-diabetic medications. Participants will be randomized in a 1:1 ratio to either the Real-Time Continuous Glucose Monitoring group (CGM group) or the control group (standard Self-Monitoring of Blood Glucose [SMBG] using conventional glucometers).

The gathered data will help determine whether the real-time visual feedback provided by CGM systems superiorly improves glycemic variability, optimizes metabolic parameters, and enhances patient adherence to lifestyle interventions and pharmacological treatment compared to conventional SMBG methods in the early stages of T2D.

Detaljeret beskrivelse

Newly diagnosed Type 2 Diabetes (T2D) represents a critical therapeutic window where intensive glycemic control can significantly preserve beta-cell function, reduce glycemic variability, and potentially induce diabetes remission. International guidelines emphasize that early, tight glycemic control is strongly associated with a better long-term prognosis and a reduced risk of micro- and macrovascular complications. However, traditional self-monitoring of blood glucose (SMBG) via finger-prick glucometers offers only static "snapshots" of glucose levels, missing critical fluctuations, asymptomatic hypoglycemia, and postprandial spikes. Routine indicators like fasting plasma glucose and glycated hemoglobin (HbA1c) fail to capture the full spectrum of glycemic variability, which is an independent risk factor for cardiovascular disease.

Recently, Continuous Glucose Monitoring (CGM) technology has emerged as a transformative tool, providing real-time, 24-hour glucose profiles. Beyond its clinical utility, CGM serves as a powerful biofeedback mechanism, motivating patients to adopt sustainable lifestyle changes-such as targeted physical activity, dietary adjustments, and improved sleep hygiene. While CGM is widely adopted in established diabetes management, its clinical utility, impact on patient adherence, and quality of life in individuals with newly diagnosed T2DM who are starting or optimizing non-insulin pharmacological therapies remain insufficiently explored.

This is a prospective, open-label, randomized controlled trial involving 80 adult patients with newly diagnosed T2DM (diagnosed within the last 3 months) recruited at the Bogomolets National Medical University. Participants may be lifestyle-controlled or receiving stable non-insulin anti-diabetic medications. Participants will be randomized in a 1:1 ratio to either the Real-Time Continuous Glucose Monitoring group (CGM group) or the control group (standard Self-Monitoring of Blood Glucose [SMBG] using conventional glucometers).

The intensive intervention period with the assigned monitoring devices (CGM or SMBG) and pedometers will last for the first 1 month, followed by a 2-month observation phase. The study consists of three outpatient visits:

  • Visit 1 (Baseline);
  • Visit 2 (1 month, end of active intervention);
  • Visit 3 (3 months, end of follow-up period).

During these visits, comprehensive metabolic, anthropometric, and psychological assessments will be conducted, including HbA1c, fructosamine, C-peptide, insulin resistance indices (HOMA2-IR), lipid profile, body mass index (BMI), waist circumference, bioimpedance body composition analysis, objective physical activity monitoring (pedometer data), and the Medical Outcomes Study Short-Form 36 (SF-36) questionnaire to evaluate health-related quality of life.

The gathered data will help determine whether the real-time visual feedback provided by CGM systems superiorly improves glycemic variability, optimizes metabolic parameters, and enhances patient adherence to lifestyle interventions and pharmacological treatment compared to conventional SMBG methods in the early stages of T2D.
