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 126 sites in 9 countries participated: France (7), Germany (10), Israel (5), South Africa (6), Spain (8), Sweden (5), Turkey (3), United Kingdom (15), United States (67).

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
If eligible based on screened assessments, subjects were randomised to 1 of the 3 treatment arms in a 2:1:1 manner (liraglutide 3.0 mg, liraglutide 1.8 mg and placebo, respectively).

Reporting Groups
  Description
Liraglutide 3.0 mg Exposed subjects received 56 weeks of once-daily subcutaneous (s.c.) injections with liraglutide, titrated from a starting dose of 0.6 mg in weekly increments of 0.6 mg to the target dose of 3.0 mg. In the 12-week follow-up period, treatment was discontinued. In addition to liraglutide 3.0 mg treatment, subjects were instructed to follow a hypocaloric diet and an exercise programme. Pre-trial treatment with metformin, glitazone or sulphonorylureas (SU) was continued throughout the trial (open-label) at unchanged dose, expect for SU that was reduced by 50%.
Liraglutide 1.8 mg Exposed subjects received 56 weeks of once-daily subcutaneous (s.c.) injections with liraglutide, titrated from a starting dose of 0.6 mg in weekly increments of 0.6 mg to the target dose of 1.8 mg. In the 12-week follow-up period, treatment was discontinued. In addition to liraglutide 1.8 mg treatment, subjects were instructed to follow a hypocaloric diet and an exercise programme. Pre-trial treatment with metformin, glitazone or sulphonorylureas (SU) was continued throughout the trial (open-label) at unchanged dose, expect for SU that was reduced by 50%.
Liraglutide Placebo Exposed subjects received 56 weeks of once-daily subcutaneous (s.c.) injections with liraglutide placebo. In the 12-week follow-up period, treatment was discontinued. In addition to placebo treatment, subjects were instructed to follow a hypocaloric diet and an exercise programme. Pre-trial treatment with metformin, glitazone or sulphonorylureas (SU) was continued throughout the trial (open-label) at unchanged dose, expect for SU that was reduced by 50%.
