A Trial Comparing the Safety and Efficacy of Semaglutide Once Weekly in Monotherapy or in Combination With One OAD in Japanese Subjects With Type 2 Diabetes

Safety and Efficacy of Semaglutide Once Weekly in Monotherapy or in Combination With One OAD in Japanese Subjects With Type 2 Diabetes Who Are Insufficiently Controlled on Diet/Exercise Therapy or OAD Monotherapy

This trial is conducted in Asia. The aim of the trial is to investigate safety and efficacy of semaglutide once weekly in monotherapy or in combination with one OAD (oral anti-diabetic drug) in Japanese subjects with type 2 diabetes who are insufficiently controlled on diet/exercise therapy or OAD monotherapy.

All subjects will continue their pre-trial treatment (diet and exercise therapy or OAD monotherapy in addition to diet and exercise therapy) during the trial.

Inclusion Criteria:

• Male or female, age at least 20 years at the time of signing informed consent
• HbA1c (glycosylated haemoglobin A1c) between 7.0% and 10.5% (53-91 mmol/mol) (both inclusive)
• Japanese subjects with type 2 diabetes mellitus (diagnosed clinically) and on stable treatment (defined as unchanged medication and unchanged dose) who are: a) on diet and exercise therapy for at least 30 days before Visit 1 (week -2). or b) on OAD monotherapy (either of SU (sulfonylurea), glinide, a-GI (a-glucosidase inhibitor) or TZD (thiazolidinediones)) within approved Japanese labelling in addition to diet and exercise therapy for at least 60 days before Visit 1 (week -2)

• Treatment with glucose lowering agent(s) other than stated in the inclusion criteria within 60 days before Visit 1 (week -2) and treatment with once weekly glucagon-like peptide-1 (GLP-1) receptor agonists within 90 days before Visit 1 (week -2). An exception is short-term treatment (below or equal to 7 days in total) with insulin in connection with inter-current illness
• Any disorder which, in the opinion of the investigator, might jeopardise subject's safety or compliance with the protocol
• History of chronic or idiopathic acute pancreatitis
• Screening calcitonin value above or equal to 50 ng/L (pg/mL)
• Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN2)
• Impaired renal function defined as estimated glomerular filtration rate (eGFR) below 30 mL/min/1.73 m^2 per modification of diet in renal disease (MDRD) formula (4 variable version)
• Acute coronary or cerebrovascular event within 90 days before randomisation (Visit 2 [week 0])
• Heart failure, New York Heart Association (NYHA) class IV
