Brief Summary:
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 or disease Intervention/treatment Phase
Diabetes Diabetes Mellitus, Type 2 Drug: semaglutide Drug: placebo Drug: Microgyn® Phase 1

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 43 participants
Allocation: Non-Randomized
Intervention Model: Crossover Assignment
Masking: None (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
Study Start Date : March 2011
Actual Primary Completion Date : January 2012

Arm Intervention/treatment
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.

Primary Outcome Measures :
  1. Area under the ethinylestradiol concentration-time curve [ Time Frame: in the 24 hour dosing interval ]
  2. Area under the levonorgestrel concentration-time curve [ Time Frame: in the 24 hour dosing interval ]

Secondary Outcome Measures :
  1. Maximum oral contraceptive concentration [ Time Frame: in the 24 hour dosing interval ]
  2. Area under the semaglutide concentration-time curve [ Time Frame: in the 24 hour dosing interval ]
  3. Maximum semaglutide concentration [ Time Frame: within the weekly dosing interval ]
  4. Percentage of subjects experiencing adverse events [ Time Frame: from week 1 to end of trial at maximum 23 weeks ]
