Inclusion Criteria:

- Subjects with type 2 diabetes

- HbA1c 7.0-10.0 % (both inclusive) with the aim of a median HbA1c of 8.3%. Accordingly,
when approximately 50% of the randomised subjects have a HbA1c above 8.3%, the
remaining subjects randomised must have a HbA1c of below or equal to 8.3%, or when
approximately 50% of the randomised subjects have a HbA1c of below or equal to 8.3%,
the remaining subjects randomised must have a HbA1c above 8.3%

Taiwan: Taichung Veterans General Hospital)

- Subjects on stable dose of 1-2 OADs (metformin [at least 1500 mg or max tolerated
dose] or metformin [at least 1500 mg or max tolerated dose] + pioglitazone [at least
30 mg]) for at least 90 days prior to screening

Exclusion Criteria:

- Treatment with insulin (except for short-term treatment due to intercurrent illness at
the discretion of the Investigator)
