Evaluation of Glycemic Changes During Exercise in Children With Type 1 Diabetes (TREAD-DIAB)

September 30, 2019 updated by: Cliniques universitaires Saint-Luc- Université Catholique de Louvain

Evaluation of Glycemic Changes and Optimization of Glycemic Control During Exercise in Children With Type 1 Diabetes Under Continuous Subcutaneous Insulin Infusion (CSII) or Multiple Daily Injection Regimen (MDI) (TREAD-DIAB Study)

The objectives of the study are: 1) to evaluate the effects of moderate exercise on SG evolution without insulin dose modification in patients with T1D under continuous subcutaneous insulin infusion (CSII) and multiple daily injection (MDI) therapy, and compare differences between these 2 groups; 2) to evaluate the impact of insulin dose modification (bolus, basal, reduction or increase, based on SG evolution profile obtained after first exercise) before and/or during moderate exercise on T1D children under CSII and MDI regimen, and compare differences between these 2 groups.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Intervention and procedures:

a) The patients will first be assigned to standardized moderate-to-vigorous exercise for SG determination; b) similar exercise will then be repeated with preemptive adaptation of insulin dose (tailored on SG evolution during first exercise) for determination of potential influences on SG evolution.

Intervention Plan:

  • At first visit (day [>18h] before exercise): setting of a Continuous Glucose Monitoring System
  • At second visit: moderate-to-vigorous exercise with treadmill.
  • At third visit (2 days after exercise): removal of CGMS
  • At fourth visit (day [>18h] before fifth visit): setting of a Continuous Glucose Monitoring System
  • At fifth visit: moderate exercise with treadmill, and insulin dose modification (basal rate, bolus, reduction, increase)
  • At sixth visit (2 days after exercise): removal of CGMS
  • Total number of visits: 6
  • The exercises will be performed between 1 and 2 hours after breakfast or after lunch; the second exercise will be performed ≥2 weeks after the first exercise.

Controls:

  • Moderate exercise with and without modification of insulin dose in MDI patients (by comparison with CSII patients). MDI patients will be matched to CSII patients according to gender, age, BMI (±0.5 z-score) and HbA1C levels (±1%) to exclude any bias in patient allocation.
  • Moderate exercise without modification of insulin dose at first visit (by comparison with modification of insulin dose).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

7 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Exclusion Criteria:

  • Non-type 1 diabetes
  • Severe neonatal asphyxia (defined as Apgar score 3 or less after 5 min), children born small for gestational age, chronic systemic disease, active malignancy, hypothyroidism, hypopituitarism, developmental delay, bladder dysfunction, obesity, carnitine deficiency, β-oxidation defect, cardiac malformations, dysrhythmia
  • Intake of drugs interfering with insulin sensitivity (e.g. corticosteroids, GH).
