Insights
Insulin glargine effectively improved glycemic control in Japanese children with type 1 diabetes, showing significant reductions in HbA1c and FPG. The treatment demonstrated good safety, with no significant impact on physical development.
Area of Science:
- Pediatric Endocrinology
- Metabolic Disorders
- Pharmacovigilance
Background:
- Post-marketing surveillance of insulin glargine in Japanese pediatric patients with type 1 diabetes.
- Evaluation of real-world clinical safety and effectiveness data.
Purpose of the Study:
- To assess the safety and efficacy of insulin glargine in Japanese pediatric patients with type 1 diabetes.
- To analyze glycemic control (HbA1c, FPG) and adverse events.
Main Methods:
- Prospective data collection over 24 weeks from 113 pediatric patients.
- Analysis of baseline characteristics, HbA1c, FPG, medication, height, weight, and adverse events.
- Safety and efficacy analyses performed on 73 and 70 patients, respectively.
Main Results:
- Hypoglycemia occurred in 3 patients (2 severe), with full recovery.
- Significant reduction in HbA1c (9.10% to 8.09%) and FPG across all patients.
- Significant HbA1c decrease in both age groups (7-12 and 13-15 years); significant FPG decrease in the younger group.
- No significant changes in BMI or obesity levels observed.
Conclusions:
- Insulin glargine therapy provides good glycemic control (HbA1c, FPG) in Japanese pediatric type 1 diabetes patients.
- The treatment is well-tolerated and safe in a clinical setting.
- Insulin glargine showed minimal impact on the physical development of pediatric patients.
Background:
We evaluated the safety and effectiveness of insulin glargine in Japanese pediatric patients with type 1 diabetes in clinical settings based on post-marketing surveillance data.
Methods:
Clinical data were collected from Japanese pediatric patients with type 1 diabetes for 24 weeks after initiation of glargine treatment. Baseline characteristics, hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), previous/concomitant medication, height, bodyweight, and adverse events were analyzed.
Results:
One-hundred and thirteen patients were enrolled from 20 medical institutions in Japan in 2003 and 2004. Of these patients, 73 were included in the safety analysis, and 70 of these patients were also included in the efficacy analysis. The 73 patients included 28 boys and 45 girls, with a mean age of 11.8 years at entry. Hypoglycemia occurred in three patients (three events) and was severe in two patients (two events); all patients recovered. In the efficacy evaluation, HbA1c at baseline and final assessment was 9.10% and 8.09% (P < 0.001) in all patients; 8.96% and 7.85% (P < 0.001) in patients aged 7-12 years (Group 1); and 9.28% and 8.37% (P = 0.010) in patients aged 13-15 years (Group 2). FPG significantly decreased in all patients and in Group 1. No significant changes were observed in body mass index or degree of obesity during the study.
Conclusions:
Glargine therapy for Japanese pediatric patients with type 1 diabetes resulted in good glycemic control in terms of HbA1c and FPG as well as good safety in clinical settings. Glargine had little effect on the physical build of patients.
