Reducing the Risk of Metabolic Decompensation in Diabetic Adolescents by Supervised School Administration of Insulin

November 4, 2021 updated by: Yale University

Reducing the Risk of Metabolic Decompensation in Adolescents With Poorly Controlled Type 1 Diabetes by Supervised School Administration of Insulin Degludec

This is a pilot study to examine and compare the efficacy of supervised injections of long acting insulins degludec and glargine to protect youth with poorly controlled type 1 diabetes (T1D) from development of ketones.

Detailed Description

This study will compare the proportion of days with fasting β-hydroxybutyrate levels ≥0.6 mmol/L at the start of the school week following weekend/holiday breaks in subjects who have been randomized to receive daily injections of I-deg or I-glar. Hypothesis: β-hydroxybutyrate levels will be lower in the morning of the first day of the school week in subjects receiving I-deg than in subjects receiving I-glar, since the long half-life of I-deg will compensate for missed insulin doses over the weekend/holidays. To remove variability due to potential non-compliance during the school week, this study will utilize our routine clinical practice of supervised insulin administration and monitoring of blood glucose and ketones during the school day.

Description

Inclusion Criteria:

  • Clinical diagnosis of T1D, diagnosed at least 12 months prior to enrollment
  • HbA1c ≥8.5%9 and <14% on enrollment
  • Taking no medications known to affect blood glucose levels other than insulin.
  • Ability to provide participant written informed consent if age 18 years, or parental written informed consent and participant assent if participant is < age 18 before any trial-related activities
  • Current regimen includes insulin detemir or I-glar, as long acting insulin
  • Willingness to use either I-glar or I-deg pens as basal insulin, and have school personnel supervise administration
  • Willingness to have school personnel supervise fasting blood β-hydroxybutyrate levels first thing in the morning at the beginning and end of each school week
  • Willingness to have school personnel supervise fasting blood glucose checks daily in the morning on school days, and eat breakfast after the fasting check

Exclusion Criteria:

  • Female participants who are pregnant, breast-feeding or planning on becoming pregnant
  • Participant (and parent if age <18) unable to read, write, and speak English.
  • Adolescents who are home schooled or no longer attending secondary school
  • Participant's school is unable to provide personnel to supervise injections of long-acting insulin or measurement blood glucose and β-hydroxybutyrate levels
  • Known or suspected allergy to trial medication(s), excipients, or related products.
  • Contraindications to study medications, including hypersensitivity to I-deg or one of its excipients, hypersensitivity to I-glar or one of its excipients, and administration of either during episodes of hypoglycaemia

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: subjects receiving insulin degludec
Youth aged 8-18 years with T1D whose diabetes is poorly-controlled (A1c ≥8.5%) will receive insulin degludec injections.
Single daily dose of insulin degludec based on their fasting blood glucose levels and current long acting insulin dose
Other Names:
  • I-degludec
Active Comparator: Subjects receiving insulin glargine
Youth aged 8-18 years with T1D whose diabetes is poorly-controlled (A1c ≥8.5%) will receive insulin glargine injections.
Single daily dose of insulin glargine based on their fasting blood glucose levels and current long acting insulin dose
Other Names:
  • I-glar

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Lower beta hydroxybutyrate levels
Time Frame: 4 months
Will test the the hypothesis that β-hydroxybutyrate levels will be lower in the morning (≥0.6 mmol/L) of the first day of the school week in subjects receiving I-deg, since the long half-life of I-deg will compensate for missed insulin doses over the weekend/holidays.
4 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Control of HbA1c levels
Time Frame: 4 months
Test the hypothesis that the longer duration of action of I-deg will lead to improvements in glycemic control measured by HbA1c (a secondary aim) and fasting glucose.
4 months
Measure of beta hydroxybutyrate levels between the 2 groups.
Time Frame: 4 months
Test the differences in frequency of elevated β-hydroxybutyrate levels when receiving supervised injections of basal insulin versus when not receiving supervised injections between the I-deg and I-glar groups
4 months
