             unchanged for 12 weeks prior to randomisation.

          3. HbA1c of >/= 7.0% and </= 10.0% at Visit 1 (screening).

          4. Age >/= 18.

          5. BMI </= 45 kg/m2 (Body Mass Index) at Visit 1 (screening).

          6. Signed and dated written informed consent by date of Visit 1 in accordance with Good
             Clinical Practice (GCP) and local legislation.

        Exclusion criteria:

          1. Uncontrolled hyperglycaemia with a glucose level > 240 mg/dl (> 13.3 mmol/l) after an
             overnight fast during placebo run-in and confirmed by a second measurement (not on the
             same day).

          2. Any other antidiabetic medication within 12 weeks prior to randomisation, except those
             defined as the permitted background therapy via inclusion criteria no. 2.

          4. Indication of liver disease, defined by serum levels of either alanine transaminase
             (ALT/SGPT), aspartate transaminase (AST/SGOT), or alkaline phosphatase above 3 x upper
             limit of normal (ULN) as determined during screening or during the placebo run-in
             period (i.e. at a visit prior to the randomisation visit, Visit 3).

          5. Impaired renal function, defined as eGFR (estimated Glomerular Filtration Rate) < 30
             ml/min (severe renal impairment, MDRD [Modification of Diet in Renal Disease] formula)
             as determined during screening or during the placebo run-in period (i.e. at a visit
             prior to the randomisation visit, Visit 3).

          6. Bariatric surgery within the past two years and other gastrointestinal surgeries that

          9. Contraindications to pioglitazone according to the local label.

         10. Contraindication to pioglitazone and/or metformin (relevant only for those patients

             labels.

         11. Treatment with anti-obesity drugs (e.g. sibutramine, orlistat) 3 months prior to

             dosage of thyroid hormones within 6 weeks prior to informed consent or any other
             uncontrolled endocrine disorder except T2D.

         15. Participation in another trial with an investigational drug within 30 days prior to
             informed consent.
