Impaired liver function defined as alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>5 times upper limit of normal (ULN) at Screening; 8. Estimated glomerular filtration rate (eGFR), calculated using the modified diet in renal disease (MDRD) formula \< 60 mL/min/1.73m2; 9.

History of major depressive disorder within 2 years before randomisation; 15. History of surgical treatment for obesity; 16. Having been exposed to any GLP-1 analogues within 6 months before Screening; 17. Treatment with orlistat, zonisamide, topiramate, phentermine, lorcaserin, bupropion and naltrexone alone or in combination or any other medications that could promote weight loss within 90 days prior to Screening; 18.
