Inclusion criteria

Female of non-childbearing potential.
Age 18-65 years (both inclusive) at the time of signing the informed consent.
Body mass index (BMI) between 18.5 and 29.9 kg/m^2 (both inclusive) at screening.
Considered to be generally healthy based on the medical history, physical examination, and the results of vital signs, electrocardiogram and clinical laboratory tests performed during the screening visit, as judged by the investigator.

Exclusion criteria

Any disorder which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol.
Any contraindications for the use of the oral contraception used in the study according to the Prescription Drug Information.
Sitting blood pressure at screening outside the range of 90-139 mmHg for systolic or 50-89 mmHg for diastolic.
Pulse outside the range of 50-89 beats/minute at screening
Use of prescription medicinal products or non-prescription drugs including any herbal medicine known to interfere with the metabolic CYP pathways, such as hypericum (St. John's Wort), ginseng, garlic, milk thistle, and echinaceae, within 14 days before screening. Exceptions are: use of routine vitamins (vitamins used within a normal dose reference interval), occasional use of paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), or topical medication not reaching systemic circulation.
Presence or history of any clinically relevant respiratory, metabolic, renal, hepatic, gastrointestinal, or endocrinological conditions.
