A Real-World Study in Patients with Type 2 Diabetes Treated with Gliclazide Modified Release during Fasting in Gulf Cooperation Council Countries: An Analysis from the International DIA-RAMADAN Study

Abstract

Introduction: The safety and effectiveness of gliclazide modified release (MR) in patients with type 2 diabetes mellitus (T2DM) who fasted during Ramadan were previously published. Here, we carried out a regional analysis among patients living in Gulf Cooperation Council (GCC) countries. Patients and Methods: DIA-RAMADAN was a real-world, observational, international, noncomparative study conducted in nine countries that included >1200 T2DM adults receiving gliclazide MR for at least 90 days before inclusion. The study comprised 2 visits: at inclusion, 6–8 weeks before the start of Ramadan (V0) and 4–6 weeks after the end of Ramadan (V1). The primary endpoint was the proportion of patients reporting ≥1 symptomatic hypoglycemic event as collected using a patient diary. Changes in HbA1c, fasting plasma glucose (FPG), and weight were also analyzed. This manuscript represents data collected in GCC countries (Kuwait, Saudi Arabia, and United Arab Emirates). Results: Data from 161 patients were analyzed: mean (SD) age 56.8 (10.6) years, 30.4% women, body mass index 29.1 (3.7) kg/m2, T2DM disease duration 6.7 (3.3) years, baseline HbA1c 7.9% (0.8). The proportions of patients reporting ≥1 symptomatic hypoglycemic event or confirmed hypoglycemia during Ramadan were 4.3% and 0.6%, respectively. No cases of severe hypoglycemia were reported. Significant reductions in main variables were observed before the start of Ramadan (V0) and 4–6 weeks after the end of Ramadan (V1): HbA1c (from 7.9 [0.8] to 7.6 [0.7]%; p value <0.001), FPG (from 143.5 [24.3] to 137.9 [25.2] mg/dL; p value = 0.031), and weight (from 79.0 [73.0–86.0] to 78.0 [72.0–85.0] kg; p value = 0.018). Conclusions: These real-world data indicate that patients with T2DM treated with gliclazide MR during Ramadan in the selected GCC countries have a low risk of hypoglycemia and maintain glycemic control and weight while fasting.
