E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male and female patients, 18-70 years of age

• Abdominal obesity (waist circumference > 102 cm in men and > 88 cm in women), according to NCEP-ATP III (2001)
• HbA1c ≥ 7 and ≤ 8.5 %. After Sponsor approval, providers might reasonably suggest more stringent HbA1c values (such as 6.5%) for selected individual patients, if this can be managed without significant hypoglycemia or other treatment adverse effects.. Appropriate patients might include those with short duration of diabetes, long life expectancy, and no significant CVD

3. Signed written informed consent
|

14. History of chronic pancreatitis or of idiopathic acute pancreatitis
15. History of metabolic acidosis, including diabetic ketoacidosis within 1 year prior to screening
16. Hemoglobinopathy or hemolytic anemia, receipt of blood or plasma products within 3 months prior to the time of screening
17. Any other clinically significant abnormality identified on physical examination, laboratory tests, ECG or vital signs at the time of screening that in the judgment of the investigator or any sub- investigator would make implementation of the protocol or interpretation of the study results difficult or would preclude the safe participation of the subject in this protocol.
18. Use of any glucose-lowering agent(s) other than metformin in the 3 months prior to screening
19. Treatment with metformin at a daily dose < 1.5 g/day
20. Use of lipid lowering therapy and/or weight lowering drugs within 3 months prior to screening
21. Use of systemic glucocorticoids (excluding topical application or inhaled forms) for one consecutive week or more within 3 months prior to the time of screening
22. Use of any investigational drug within 3 months prior to screening
23. Patients considered by the investigator or any sub investigator as inappropriate for this study for any medical, psychological, social, or geographical reason (e.g. patients that do not take their breakfast in the morning, patients unable to fully understand the nature, scope, and possible consequences of the study; patients unable to fully understand patient’s study documents; impossibility to meet specific protocol requirements, such as scheduled visits; being unable or unwilling to do blood glucose monitoring using the sponsor-provided blood glucose meter at home; likelihood of requiring treatment with drugs not permitted by the clinical study protocol, night shift workers, etc)
24. Patient is the Investigator or any Sub-Investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol.
25. Patient who withdraws consent during the screening.
26. Any contra-indication to metformin according to local labelling
27. Clinically relevant history of gastrointestinal disease associated with prolonged nausea and vomiting, including (but not limited to): gastroparesis, unstable (i.e. worsening) and not controlled (i.e. prolonged nausea and vomiting) gastroesophageal reflux disease within 6 months prior to the time of screening
28. History of unexplained pancreatitis, chronic pancreatitis, pancreatectomy, stomach/gastric surgery, inflammatory bowel disease
29. Personal or immediate family history of medullary thyroid cancer (MTC) or genetic conditions that predispose to MTC (e.g. multiple endocrine neoplasia syndromes)
30. Any previous treatment with lixisenatide (e.g. participation in a previous study with lixisenatide)
31. Allergic reaction to any GLP-1 receptor agonist in the past (e.g. exenatide, liraglutide) or to metacresol.
