Inclusion criteria

•Healthy male or female subjects (based on assessment of medical history, physical examination and clinical laboratory data at screening, as judged by the investigator)

•Age between 18 and 55 years (both inclusive) at the time of signing informed consent

•Body mass index (BMI) between 20 and 30 kg/m^2 (both inclusive)

Exclusion criteria

•Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearing potential not using an adequate contraceptive method. Women of child-bearing potential must use an effective method of birth control for the duration of the trial and for 5 weeks following the last dose of semaglutide. Only highly effective methods of birth control are accepted (i.e. one that results in less than 1 % per year failure rate when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine device) or sexual abstinence or vasectomised partner

•Any clinically significant disease history, in the opinion of the investigator, or systemic or organ disease including: cardiac, pulmonary, gastrointestinal, hepatic, neurologic, renal, genitourinary and endocrine, dermatologic or hematologic diseases

•Use of prescription or non-prescription systemic or topical medicinal products (except routine vitamins, acetylsalicylic acid, paracetamol and contraceptives) within 3 weeks (or within 5 half-lives of the medicinal product, whichever is longest) prior to the first dosing of semaglutide

•History of drug/chemical substance abuse within 1 year from screening, or a positive result in the urine drug test

•History of alcohol abuse within 1 year from screening, or a positive result in the alcohol urine test, or consumption of more than 21 units (male)/14 units (female) of alcohol weekly (one unit of alcohol equals about 250 mL of beer or lager, one glass (120 mL) of wine, or 20 mL spirits)

•Smoking or use of any nicotine products (including nicotine patches, gum etc.) in the last 3 months prior to screening or a positive nicotine test
