Comparison of the Efficacy of Rapid-acting Aspart and Faster Acting Aspart Within the Context of Single-hormone Closed-loop Strategy at Regulating Postprandial Glucose Levels
An Open-label, Double-blind, Randomized, Two-way, Cross-over Pilot Study to Provide Preliminary Evidence of the Efficacy of Rapid-acting Aspart Compared to Faster Acting Aspart Within the Context of Single-hormone Closed-loop Strategy at Regulating Postprandial Glucose Levels in Adults With Type 1 Diabetes
Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosages based on the sensor's readings.
The objective of this pilot study is to inform both the decision whether to conduct a confirmatory study and the design of the larger confirmatory trial. In addition, we want to estimate postprandial glucose levels parameters and confidence interval in an 11-hour in-patient study with standardized conditions in adults with type 1 diabetes, estimate the size and direction of the treatment effect.
Faster insulin Aspart (FiAsp) will provide preliminary evidence of efficacy to regulate postprandial glucose levels compared to rapid-acting Aspart in adults with type 1 diabetes using insulin pump therapy.

Descrizione
Inclusion Criteria:
- Males and females ≥ 18 years of old.
- Clinical diagnosis of type 1 diabetes for at least one year.
- The subject will have been on insulin pump therapy for at least 6 months.
- HbA1c ≤ 12%.
Exclusion Criteria:
- Using a patch-pump (e.g. Omnipod)
- Clinically significant nephropathy, neuropathy or retinopathy as judged by the investigator.
- Recent (< 6 months) acute macrovascular event e.g. acute coronary syndrome or cardiac surgery.
- Ongoing or planned pregnancy.
- Breastfeeding.
- Severe hypoglycemic episode within two weeks of screening.
- Current use of glucocorticoid medication (except low stable dose and inhaled stable treatment).
- Known or suspected allergy to the trial products or meal contents.
- Other serious medical illness likely to interfere with study participation or with the ability to complete the trial by the judgment of the investigator.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Comparatore attivo: Rapid-acting Aspart
Rapid-acting Aspart will be used to regulate glucose levels
|
The participant's insulin pump will be used to infuse insulin
The Dexcom G4 Platinum will be used to measure glucose levels
Subjects will be admitted at IRCM at 9:30. An intravenous catheter will be inserted into an arm or a hand vein for blood sampling purposes. A cartridge containing rapid-acting Aspart or faster acting Aspart will be placed in the insulin pump. Closed-loop strategy will start at 10:00 until 21:00. A glucose sensor reading will be entered manually into the computer every 10 minutes. The computer will generate a recommendation for the basal rates of insulin delivery. Pumps' parameters will then be changed manually to implement the computer generated recommendations. At 12:00, a lunch meal will be served. An insulin bolus will be given 15 minutes before the meal. At 17:00, a dinner meal will be served. As recommended, an insulin bolus will be given at the time of the meal. Each subject will ingest the same meals during both visits. Venous blood samples will be obtained for the measurement of plasma glucose and insulin concentrations. Blood samples will be taken every 20 minutes. |
