8. Any antidiabetic medication (with the exception of metformin and/or insulin background therapy) within 8 weeks prior to Visit 1A and until Visit 2
9. Treatment with weight reduction medications (including anti-obesity drugs) within 3 months prior to Visit 1A and until Visit 2
10. History of weight-loss surgery or current aggressive diet regimen (according to investigator assessment) at Visit 1A and until Visit 2
11. Treatment with systemic corticosteroids for > 1 week within 4 weeks prior to Visit 1A and up to Visit 2
Inhaled or topical use of corticosteroids (e.g. for asthma/chronic obstructive pulmonary disease) is acceptable.
12. Change in dose of thyroid hormones within 6 weeks prior to Visit 1A or planned change or initiation of such therapy before Visit 2
13. Known hypersensitivity or allergy to the investigational products or their excipients
14. Impaired renal function defined as estimated Glomerular Filtration Rate (eGFR) < 60 ml/min/1.73m² (according to Zappitelli formula) as measured by the central laboratory at Visit 1A
15. Indication of liver disease defined by serum level of either alanine transaminase (ALT), aspartate transaminase (AST) or alkaline phosphatase above 3 fold upper limit of normal

17. Any documented active or suspected malignancy or history of malignancy within 5 years prior to Visit 1A, except appropriately treated basal cell carcinoma of the skin or in situ carcinoma of uterine cervix
18. Blood dyscrasias or any disorders causing haemolysis or unstable red blood cells (e.g. malaria, babesiosis, haemolytic anaemia)
