Introducing Biosimilar Insulin Glargine to the Treatment Regimen of Children and Youth with Type 1 Diabetes in Mali
- Conditions
- Type 1 Diabetes (T1D)
- Interventions
- Drug: biosimilar insulin glargine
- Registration Number
- NCT06624943
- Lead Sponsor
- Life for a Child Program, Diabetes Australia
- Brief Summary
This study aimed to evaluate the impact on blood glucose control and quality of life in children and youth with type 1 diabetes in Mali by switching the insulin regimen from human insulin via needle and syringe, to long-acting biosimilar insulin glargine delivered by reusable pens combined with short-acting insulin via needle and syringe.
- Detailed Description
Analog insulins are widely used in middle- and high-income countries. However, use of analog insulin remains limited in lower-income countries due to their increased cost and lack of access, and human insulin remains the mainstay of treatment in these settings.
Long-acting (basal) analog insulin such as glargine have the benefit of a longer duration (up to 24 hours) and a minimal peak action, and generally, only one injection per day is required. Although glargine insulin has been shown to reduce the risk of overnight hypoglycemia, consistent improvement in blood glucose control (measured by HbA1c) when compared to human insulin has not been shown, and its impact on quality of life is also inconclusive. Furthermore, these studies have all been done in highly resourced countries.
Life for a Child (LFAC) has been providing diabetes supplies (insulin, syringes, meters and strips for blood glucose self-monitoring), diabetes-related education, mentoring and technical support to Santé Diabète in Mali since 2008. In 2021, LFAC commenced supplying Basaglar (glargine) insulin with insulin pen devices (HumaPen Ergo ll). This provided a unique opportunity to investigate the effect of introducing glargine (Basaglar) insulin in the low-resource setting of Mali, one of the world's poorest countries.

Group Intervention Description Intervention biosimilar insulin glargine Switched to once daily injection of biosimilar insulin glargine via reusable pen and three mealtime bolus insulin injections of short-acting human insulin via needle and syringe
- Primary Outcome Measures
Name Time Method HbA1c Baseline, 3-, 6-, 9- and 12-month follow-up visits HbA1c was measured at each study time point using point of care testing via a Siemens DCA calibrated to international standards (DCA Vantage™ Analyzer (Siemens Healthcare Diagnostics, Tarrytown NY, US)). For HbA1c readings \>14% (\>130 mmol/mol), the maximum reading of this analyser, HbA1c was recorded as 14% (130 mmol/mol).
- Secondary Outcome Measures
Name Time Method Episodes of diabetic ketoacidosis Baseline, 3-, 6-, 9- and 12-month follow-up visits Diabetic ketoacidosis was defined as hyperglycaemia (BGL\>11mmol/L/200mg/dL) with a venous pH\<7·3 or serum bicarbonate \<15mmol/L and ketonuria and/or ketonaemia
Episodes of severe hypoglycaemia Baseline, 3-, 6-, 9- and 12-month follow-up visits Severe hypoglcaemia was defined as an event with severe cognitive impairment (with or without coma and convulsions) requiring assistance by another person to administer carbohydrates, glucagon, or intravenous dextrose to restore glycaemia
Diabetes Quality of Life in Youth - Short Form Baseline, 6- and 12-month follow-up visits The 21-item Diabetes Quality of Life in Youth - Short Form scale (TC Skinner et al., Diabetologia 2006; 49, 621-628) was administered to participants in both study arms To assess the psychosocial impact of their respective insulin treatment regimens
Participant self-reported satisfaction (intervention arm only) 12-month follow-up visit A 5-item structured questionnaire was administered to participants in the intervention group to evaluate their satisfaction with the new insulin regimen, experience of using reusable insulin pens, and their experience of hypo- and hyperglycaemic episodes over the study period
Feedback from local HCPs on implementation of the study intervention At 12 months A 6-item questionnaire was administered to HCPs at the end of the study, to obtain feedback on the training they received, their confidence in teaching youth and families on switching to the new insulin regimen, and opinion on its impact on hypo- and hyperglycaemic episodes.
