Description as written by the study sponsor.

This study compares the effect and safety of 2 dose schedules for semaglutide (study medicine) in people with type 2 diabetes previously treated with a diabetes medicine similar to semaglutide. The study will also evaluate the use of a new pen-injector for semaglutide used to inject medicine under the skin, at a new dose of 2 mg. People taking part in the study will take this medicine together with their current diabetes tablets other than semaglutide. Participants will either get a start dose of 0.25 mg semaglutide or 0.50 mg semaglutide, and the dose will be gradually increased to 2.0 mg semaglutide - which treatment is decided by chance. Participants will inject semaglutide under the skin once a week, any time of the day. When the dose reaches 2.0 mg semaglutide, participants will inject the medicine with a new type of pen-injector. The study will last for about 24 weeks. Participants will have 9 visits and 1 phone call with the study doctor. At 9 visits participants will have blood taken and at 2 visits they will have eye examination done. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period. Women who are able to get pregnant will be checked 10 times for pregnancy via urine tests.
