A Multiple Dose Study Investigating Pharmacokinetics and Pharmacodynamics of Subcutaneous NNC0363-0845 in Participants With Type 1 Diabetes

NN1845-4886

This study is designed to investigate the movement of insulin NNC0363-0845 throughout the body and how it works for the treatment of type 1 diabetes mellitus. The aim of the study is to improve clinical outcomes for patients with type 1 diabetes mellitus by better controlling the blood sugar levels. Participants will get insulin NNC0363-0845 as well as insulin detemir (Levemir®). NNC0363-0845 is a new insulin molecule designed to provide blood sugar-dependent insulin action, while insulin detemir is commonly used and prescribed by doctors. Participants will get subcutaneous (under your skin) injections of insulin NNC0363-0845 (study medicine) up to 6 times daily for 3 days, and of insulin detemir up to 6 times daily for another 3 days. Which medication participants receive first and which second, insulin NNC0363-0845 or insulin detemir, is decided by chance. The study will last for about 6 weeks up to a maximum of 14 weeks. Participants will have 2 in-house visits (where participants will stay at the site for 4 nights) and 5 outpatient visits with the study doctor. Participants will have frequent contact with the study doctor during the study. During the in-house visits, two intravenous catheters (a thin tube inserted into a vein) will be inserted for blood sampling and infusions. Interested parties may not participate in the study if the study doctor believes it will affect their health negatively. Women cannot take part if they are of childbearing potential.
