This clinical trial is conducted in Europe. The purpose of the trial is to investigate the influence on the pharmacokinetics (the rate at which the trial drug is eliminated from the body) of an oral contraceptive combination drug after multiple administration of semaglutide in female subjects with type 2 diabetes.

Condition Intervention Phase
Diabetes Mellitus, Type 2
Drug: semaglutide
Drug: placebo
Drug: Microgyn®
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Pharmacokinetics Study
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open-label, One-sequence Cross-over, Single Centre Trial Investigating the Influence of Semaglutide on Pharmacokinetics of Ethinylestradiol and Levonorgestrel in an Oral Contraceptive Combination Drug After Multiple Dose Administration of Semaglutide in Subjects With Type 2 Diabetes

Primary Outcome Measures:
  • Area under the ethinylestradiol concentration-time curve [ Time Frame: in the 24 hour dosing interval ] [ Designated as safety issue: No ]
  • Area under the levonorgestrel concentration-time curve [ Time Frame: in the 24 hour dosing interval ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Maximum oral contraceptive concentration [ Time Frame: in the 24 hour dosing interval ] [ Designated as safety issue: No ]
  • Area under the semaglutide concentration-time curve [ Time Frame: in the 24 hour dosing interval ] [ Designated as safety issue: No ]
  • Maximum semaglutide concentration [ Time Frame: within the weekly dosing interval ] [ Designated as safety issue: No ]
  • Percentage of subjects experiencing adverse events [ Time Frame: from week 1 to end of trial at maximum 23 weeks ] [ Designated as safety issue: Yes ]

Enrollment: 43
Study Start Date: March 2011
Study Completion Date: January 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: One-sequence cross-over arm Drug: semaglutide
Semaglutide will be administered once weekly by s.c. (under the skin) injections in the abdomen. A total of 13 doses of semaglutide will be administered according to a predefined dosing scheme
Drug: placebo
Placebo semaglutide will be administered once for securing eligibility of subjects (willingness and ability to self inject) at the screening visit.
Drug: Microgyn®
Microgyn® will be given as once daily oral dosing in two periods, each of 8 days' duration. One tablet contains levonorgestrel 0.15 mg and ethinylestradiol 0.03 mg.
