Résumé de l'étude

An increase in the prevalence of overweight and obesity among people with type 1 diabetes (T1D) is evident. These individuals typically have elevated long-term blood sugar levels, increased body weight, and require larger doses of insulin. Additional therapies for intensified insulin treatment have been developed to better control blood sugar and reduce the risk of vascular complications. Promising medications include hormone analogs. These hormone analogs mimic natural hormones in the body that play a role in regulating blood sugar levels and appetite. Thus, these medications work by mimicking the effects of natural hormones, stabilizing blood sugar levels and reducing feelings of hunger. Studies show that the combination of these medications with insulin in T1D improves blood sugar control, reduces insulin dosage, and decreases body weight. We plan a clinical study to test the safety and efficacy of automatic insulin delivery systems (AID) in combination with Tirzepatide in individuals with T1D. Tirzepatide is a relatively new medication that mimics the action of two natural hormones. The study medication is called Mounjaro® and contains the active ingredient Tirzepatide. The results are expected to provide new insights into the use of this therapy in individuals with T1D. Participants will be randomly assigned to one of two groups (experimental or control group). The experimental group will receive Mounjaro® initially once weekly for four weeks at a lower dose and then for twelve weeks once weekly at a higher dose. The control group will not receive the study medication. Both groups will receive standard therapy. The study will be conducted in Switzerland at the Cantonal Hospital of Olten. It is planned to enroll 42 participants in the study.

Intervention étudiée

This study aims to demonstrate whether the application of the study medication Mounjaro®, which contains an active ingredient that mimics the action of two natural hormones, has a positive impact on the duration during which the blood sugar level of adults with type 1 diabetes remains within the target range.

Critères d'inclusion/exclusion
Inclusion Criteria: 1. Participants with diagnosed T1D for at least 12 months. 2. Aged between 18 to 65 years old (inclusive). 3. Currently on AID therapy for at least three months. 4. HbA1C higher or equal to 6.5% and less or equal to 10%. 5. BMI =23 kg/m2. 6. Willing to use once-weekly tirzepatide for at least 16 weeks (including four weeks of up-titration and 12 weeks of treatment) 7. Willing to wear a Dexcom G7 Sensor and share devices (AID) data uploads. 8. Willingness not to start any new non-insulin glucose-lowering agent during the trial (including metformin/biguanides, pramlintide, DPP-4 inhibitors, sodium-glucose cotransporter 2 inhibitors [SGLT2 inhibitors], and nutraceuticals). 9.
