Real-world Safety and Effectiveness of Insulin Glargine 300 U/mL in Participants with Type 2 Diabetes Mellitus During the Period of Ramadan in Four Countries (Egypt, Jordan, Lebanon, and Turkey): A Prospective Observational Study

Aim This non-interventional observational study aimed to describe the clinical outcomes of patients with T2DM treated with Gla-300 during the period of Ramadan. Background Type 2 diabetes mellitus (T2DM) patients who decide to fast during the holy month of Ramadan face several challenges in achieving glycemic control without increasing the risk of hypoglycemia. Insulin glargine-300 (Gla-300) has well-established safety and efficacy in improving glycemic control in multiple randomized clinical trials (RCTs). However, limited evidence is available regarding its safety and effectiveness during fasting. Objective The objective of this study was to assess the safety and clinical outcomes of insulin glargine-300 (Gla-300) in T2DM patients before, during, and after Ramadan. Methods We conducted a prospective, observational, non-comparative, multicenter study on patients with T2DM currently treated with Gla-300 who planned to fast and continue on Gla-300 during Ramadan in four countries (Egypt, Jordan, Lebanon, and Turkey). The study outcomes included the change in glycemic parameters and incidence of hypoglycemia before, during, and after Ramadan. Results One hundred and forty T2DM patients were included. Nearly 61% of the included patients had a duration of diabetes of <10 years. The mean Gla-300 daily doses during the pre-Ramadan, Ramadan, and post-Ramadan periods were 22.2 ±7.4, 20.4 ±7.5, and 22.5 ±4.7 IU, respectively. The mean change values from pre-Ramadan to Ramadan and post-Ramadan were -1.7 ±6.9 IU and 0.5 ±4.7 IU, respectively, among the included patients. The mean HbA1c decreased during the study period initiating from 7.9% ±1.4% pre-Ramadan to 6.9% ±0.4% post-Ramadan. The overall HBA1c target value was 6.9% ±0.4%, while the HbA1c target was achieved by 29 patients (21.9%). The mean fasting blood glucose (FPG) showed a reduction from baseline value in the post-Ramadan period by -0.9 ±2.3 mmol/L. Five patients (3.57%) had symptomatic documented hypoglycemia during Ramadan, and none was considered to have severe hypoglycemia. Conclusion Our study showed that insulin Gla-300 maintained the glycemic control of T2DM patients who decided to fast during the holy month of Ramadan without increasing the risk of hypoglycemia. Regular self-monitoring of blood glucose levels during Ramadan is highly recommended to avoid possible complications.
