Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A total of 133 centres in 15 countries: Austria (4), Denmark (6), Finland (5), France (5), Germany (14), Ireland (4), Macedonia (1), Norway (4), Poland (9), Romania (3), Slovenia (3), Spain (4), Sweden (2), Switzerland (4) and United States (65).

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Eligible subjects were subjects with type 2 diabetes being treated with oral anti-diabetic (OAD) therapy(ies) for at least 3 months prior to the study. Three subjects were exposed to study drug prior to randomisation, and thus only included in safety analysis set.

Reporting Groups
  Description
Liraglutide -> Liraglutide -> Liraglutide Liraglutide 1.8 mg once daily + OAD (metformin monotherapy, sulphonylurea (SU) monotherapy or a combination), Weeks 0-26 (double-blinded) continued to receive liraglutide 1.8 mg once daily + OAD in extension period (weeks 26-52 and 52-78)
Exenatide -> Liraglutide -> Liraglutide Exenatide 10 mcg twice daily + OAD (metformin monotherapy, sulphonylurea (SU) monotherapy or a combination), Weeks 0-26 (double-blinded) switched to receive liraglutide 1.8 mg once daily + OAD in extension period (weeks 26-52 and 52-78)
