A Trial Comparing Insulin Degludec/Liraglutide, Insulin Degludec, and Liraglutide in Chinese Subjects With Type 2 Diabetes Inadequately Controlled on Oral Antidiabetic Drugs (OADs)

This trial is conducted in Asia. The aim of this trial is to confirm the efficacy of insulin degludec/liraglutide in controlling glycaemia in Chinese subjects with type 2 diabetes mellitus inadequately controlled on oral antidiabetic agents
