Inclusion criteria
Inclusion criteria: . Male and/or female subjects 18-70 years of age, inclusive, with BMI 27-50 kg/m2 inclusive, and with Type 2 diabetes mellitus as defined by the American Diabetes Association15 for at least 4 months. 2. Subjects on stable oral anti-diabetes regimens (no changes in agents or doses for at least 4 months) consisting of sulfonylurea (SU—any locally approved sulfonylurea), metformin (Met), thiazolidinedione (TZD—rosiglitazone or pioglitazone), sitagliptin, meglitinides (MEG--repaglinide or nateglinide), or alpha-glucosidase inhibitors (AGI-- acarbose or miglitol). These agents may be used as monotherapy or in combinations found in the table in protocol (page 24). Each background diabetes medication should be taken at maximally allowable doses per prescribing information or taken at doses which are adequate for study participation in the judgement of the investigator. Note: Doses of background diabetes medications may not be changed during the course of the study except in specific circumstances (See Section 6.1 for Diabetes Management details). For combination medications, each component of the combined tablet must satisfy the above criteria. 3. Screening HbA1c between 6.5% and 10%, inclusive. 4. Week -1 fasting plasma glucose = 270 mg/dl (15 mmol/L). 5. Subjects must have documentation of an appropriate ophthalmologic exam (including dilated examination of the fundus) by a qualified health care professional, during the 12 months prior to randomization. 6. For women of childbearing potential, a negative serum pregnancy test will be required prior to study inclusion. Female subjects must be surgically sterile or be postmenopausal or must agree to use effective contraception during the study. For the United Kingdom only, acceptable methods of contraception are found in Section 4.3.2.1. For all other countries, the definition of effective contraception will be based on the judgement of the Investigator or a designated associate. Oral contraceptive use is permitted if used for at least 3 months before starting study medication. 7. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the trial. 8. Subjects who are able to comply with scheduled visits, treatment plan (including diet and exercise program), home blood glucose monitoring, laboratory tests, and other trial procedures. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: 1.Women who are pregnant or lactating, or who are actively planning to become pregnant. 2.Subjects with clinically significant abnormalities identified during the screening process. Specific exclusions include: a. Subjects with blood pressure reading of systolic BP >155 mm Hg and/or diastolic BP>95 mm Hg (confirmed by repeat measurement at the screening visit) or requiring new pharmacologic treatment or change in current treatment according to local guidelines for diabetic patients; b.Subjects with clinically significant cardiovascular disease, defined as unstable coronary heart disease (CHD), cerebrovascular disease (CVD) or peripheral vascular disease (PVD) and/or an event/intervention during the past 6 months; Note: Clinically stable subjects with a history of CHD, CVD or PVD, provided that the level of exercise proposed in the trial is deemed safe and appropriate for the subject may be included. c.Subjects with dyslipidemia requiring new pharmacological treatment or a change in current treatment according to local guidelines for diabetic patients; d.Subjects with renal disease including: •Any history of nephrotic syndrome, •Chronic renal failure and/or serum creatinine above the upper limit of normal (ULN) for metformin-treated patients or >1.5 times the ULN for patients not treated with metformin. e.Subjects with abnormal screening TSH values; f.Subjects with significant hepatobiliary disease including: •History of hepatitis B or C infection and/or, •Aspartate aminotransferase or alanine aminotransferase =2 times the ULN. g.History of HIV infection or use of antiretroviral agents; h.Subjects with any prior history of malignancy except for: •Basal cell carcinoma of the skin curatively treated, •Other malignancies (regardless of site) that have been cancer-free for > 5 years prior to screening. i.Subjects with gastrointestinal disease, surgery limiting drug absorption or previous history of surgical procedure for weight loss; j.Clinical laboratory tests outside the pre-specified exclusionary limits; k.Subjects with a history of CNS disorder including: •A mood disturbance that meets the criteria for a Major Depressive Disorder within the last 10 years prior to screening, defined as requiring hospitalization, two or more episodes of a major depressive disorder or any previous suicide attempt.: •Use of antidepressants that are known to increase weight; Note: Subjects on a maintenance dose of other permitted antidepressants for a major depressive disorder, stable and in remission for at least 3 months prior to screening, and who plan to continue this treatment during the entire trial may be included. •Subjects with a score of =10 or who score positively on the item 9 addressing suicidal ideas on the PHQ-9; •Subjects with psychotic conditions or on antipsychotic pharmacotherapy; •Subjects with seizure disorders who: 1.Are not controlled by current antiepileptic treatment, and/or 2.Are taking antiepileptic drugs (AEDs) known to affect weight positively or negatively unless these medications have been taken at a stable dose for at least 6 months and the subject’s weight has been stable over the same time period, and/or •That may increase the risk of a drug-drug interaction. •Subjects with neurological disorders that are acute, chronic relapsing, progressive or have an unpredictable course. 3.Subjects who use marijuana (determined by medical history
