A Study to Compare the Uptake Into the Blood of Two Strengths of Somapacitan After Injection Under the Skin in Healthy Subjects

Phase 1

Completed

• Conditions: Growth Hormone Deficiency; Healthy Volunteers
• Interventions: Drug: somapacitan

• Registration Number: NCT03905850
• Lead Sponsor: Novo Nordisk A/S

Brief Summary

This study will compare two strengths of the new long-acting growth hormone somapacitan. The aim of this study is to test if both strengths are taken up in the blood in the same way. During three separate dosing visits participants will get a total of 3 injections of the study medicine. Somapacitan is not yet approved and therefore cannot be prescribed by a doctor outside of this study. The study duration is between 10 and 15 weeks. Participants will have 17 visits with the study doctor. Three visits will each comprise 6 in-house days with overnight stays. In total, at least 15 overnight stays at the clinic. There will be blood samplings during the study. Participants must come to the clinic regularly for these blood samplings. People who have already received growth hormones in the past or who are growth hormone deficient cannot be in the study. People cannot be in the study if the study doctor thinks that there are risks for their health. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period.
