Summary

This trial is testing if semaglutide, a once-weekly injectable medication, can improve glucose control in those with type 1 diabetes when used with a closed-loop insulin system.

Who is the study for?
This trial is for individuals with type 1 diabetes who have been using an insulin pump for at least 3 months and have a glycated hemoglobin (HbA1c) level up to 11%. Participants should not be pregnant, breastfeeding, or planning pregnancy and must agree to use effective birth control. They shouldn't have a history of certain thyroid cancers, pancreatitis, gallbladder disease, severe hypoglycemia recently, or any serious medical condition that could affect participation.
What is being tested?
The study tests if weekly injections of Semaglutide can improve blood sugar control in people with type 1 diabetes when used alongside a closed-loop insulin system (artificial pancreas). The trial compares the effects of Semaglutide against a placebo over an outpatient therapy period including usual treatment plus four weeks of closed-loop therapy.
What are the potential side effects?
Potential side effects may include digestive issues like nausea or vomiting due to the effect on gastric emptying; low blood sugar levels; possible inflammation of organs such as the pancreas; and allergic reactions. As this drug affects appetite and digestion, changes in eating habits might also occur.

Experimental Treatment
Active Control
Group I: Semaglutide, Ozempic® (at maximum tolerated dose) + closed-loop insulin systemExperimental Treatment1 Intervention
Semaglutide is a Glucagon-Like Peptide 1 Receptor Agonist. It stimulates GLP1 in the body, which allows for increased satiety, reduced glucagon levels, delayed gastric emptying, and in some, increased insulin secretion. It is a once per week subcutaneous injection.
Group II: Placebo + closed-loop insulin systemActive Control1 Intervention
