The trial is a placebo-controlled, double-blinded within cohorts, randomized, multiple ascending dose trial with a sequential trial design. The primary outcome is to investigate the safety and tolerability of ascending subcutaneous weekly doses of NNC0361-0041 plasmid in patients with T1D.

Official Title

A Multiple Ascending Dose Trial Investigating Safety, Tolerability and Pharmacokinetics of NNC0361-0041 Administered Subcutaneously to Patients With Type 1 Diabetes Mellitus


A total of 48 patients with T1D are planned to be studied in 4 cohorts of 12 patients (9 on active and 3 on placebo treatment). Within each cohort, sentinel enrollment will occur and safety assessment will occur before remaining participants are enrolled. The treatment period will be 12 weeks with once weekly dosing leading to 12 doses in total. Dose escalation will occur after data safety review (as described in section 4.9.2). An MMTT to assess insulin secretion will be done at baseline, 1, 3, 6, and 12 months. The follow-up (FU) period will be 1 week after the last dose, as well as 4, 6 and 12 months after the first dose.
