This Phase 2 dose-ranging study will evaluate the efficacy, safety and tolerability of a range of doses of GW677954 compared with placebo over sixteen weeks of treatment in subjects with T2DM (Type 2 Diabetes Mellitus).

Study summary:

A Multicenter, Randomized, Double-Blind, Double-Dummy, Parallel-Group, Placebo-Controlled, Study To Evaluate Efficacy, Safety And Tolerability Of Oral GW677954 Capsules (2.5, 5, 10, 15 And 20 Mg Once A Day) As A Monotherapy (Diet and/or exercise treated) Or As An Add-On To Metformin For 16 Weeks Duration In Subjects With Type 2 Diabetes Mellitus


Inclusion criteria: - Subjects with T2DM as defined by the criteria of the ADA and/or recognized by WHO Expert Committee on the Diagnosis and Classification of Diabetes Mellitus [American Diabetes Association, 2004], for at least 3 months preceding screening (see Section 15.3, Appendix 3:, "Diagnosis and Classification of Diabetes Mellitus"). - To be eligible for Randomization into the trial, a subject must satisfy all of the following glycemic criteria: - HbA1c level via central laboratory at the pre-screening visit - If HbA1c ≥ 8.0% but ≤ 10.0%: subject may proceed to Randomization; - If HbA1c ≥ 7.8% but < 8.0%, subject not eligible to proceed, but may be retested once to establish eligibility (or lack thereof). If HbA1c level ≥ 8.0% upon retest, subject is eligible to proceed; otherwise they should be withdrawn. - If HbA1c < 7.8%, subject not eligible to proceed (no retest allowed). - FPG level via central laboratory at the pre-screening visit must be < 270 mg/dL (15.0 mmol/L).

Exclusion criteria: Exclusion Criteria: - Metabolic Disease including: - Diagnosis of Type 1 diabetes mellitus - Uncorrected thyroid dysfunction. (NOTE: subjects with hypothyroidism on a stable dose of thyroid replacement therapy for at least 1 month prior to Screening, and who have a screening thyroid stimulating hormone (TSH) within the upper limit of normal may participate). - Significant weight gain or loss (defined as > 5% of total body weight) within the 3 months prior to Screening. - Previous use of insulin for treatment of hyperglycemia within 3 months of Screening. - History of recent clinically significant cardiovascular disease including: - History or ECG evidence of prior myocardial infarction within 6 months prior to Screening. - Current unstable angina or history of unstable angina in past 6 months. - Coronary revascularization including percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass graft (CABG) surgery that is either planned or occurred in the 6 months prior to Screening. - Clinically significant arrhythmia or valvular heart disease. - Congestive heart failure (CHF) with New York Heart Association (NYHA) Class II-IV symptoms (see Section 15.4, Appendix 4). - Blood pressure > 160/100 mmHg or resting heart rate > 100 bpm. Note: subjects using antihypertensives [e.g., beta blockers, angiotensin converting enzyme (ACE) inhibitors, angiotensin II antagonists, calcium channel blockers and diuretics] must be on stable doses during the 30 days prior to Screening and during the trial. - Has a QTc interval (Bazett's) > 440 msec in males and > 450 msec in females at Screening. - Clinically significant ECG abnormalities which, in the opinion of the Investigator, may affect the interpretation of safety data, or which otherwise, contraindicates participation in a clinical trial with a new chemical entity. - History of chronic pancreatitis. - Familial hypercholesterolemia. - TGs ≥800 mg/dL (8.96 mmol/L) at Screening. - Serum creatinine at screening > 1.4 mg/dL (124 µmol/L) for women, or > 1.5 mg/dL (133 µmol/L) for men. - Clinically significant anemia defined by hemoglobin concentrations <12.0 g/dL or < 120.0 g/L for males and < 11.0 g/dL or < 110.0 g/L for females. - History of significant co-morbid diseases (e.g., cholelithiasis, gastrointestinal disease, etc.) that would preclude participation in the study. - Documented history of hepato-biliary disease including a history of, or positive laboratory results for hepatitis (hepatitis B surface antigen and/or hepatitis C antibody) at Screening, and/or clinically significant hepatic enzyme elevation including: •Any one of the following enzymes greater than 2.5 times the upper limit of normal (ULN) value at Screening: - Alanine aminotransferase (ALT) - Aspartate aminotransferase (AST) - Alkaline phosphatase (ALP) - Total or direct bilirubin > 1.5 times the ULN at Screening, unless consistent with presumed or diagnosed Gilbert's disease. - History of metabolic acidosis, rhabdomyolysis, myalgia, myositis or myopathy after taking statins or fibrates. - Any subject who has withdrawn therapy due to AEs after taking a PPARγ or a PPARα/γ dual agonist, either marketed (e.g., troglitazone, rosiglitazone or pioglitazone) or under current or previous clinical investigation. - Signs or symptoms of myositis at Screening (or upon 1 repeat test), and/or creatinine phosphokinase (CPK)≥3.0 times ULN - Is currently taking or has taken any of the following medications in the 3 months prior to the pre-screening visit: - Anti-obesity agents (including fat absorption blocking agents) - St. John's Wort - Warfarin and other oral anticoagulants (excluding aspirin and non-steroidal anti-inflammatory drugs) - Digoxin - Oral or injectable corticosteroids (inhaled and intranasal steroids are acceptable) - Use of antidiabetic agents (other than metformin) in the 2 months prior to the pre-screening visit. - Use of TZDs in the 3 months prior to the pre-screening visit. - Methotrexate, cyclosporine or monoclonal antibodies (e.g., alemtuzumab, gemtuzumab ozogamicin, rituximab, trastuzumab, ibritumomab, tiuxetan) for rheumatoid arthritis or psoriasis. - Atypical antipsychotic medications [e.g., aripiprazole (Abilify), risperidone (Risperdal), clozapine (Clozaril), olanzapine (Zyprexa), quetiapine (Seroquel), and ziprasidone (Geodon)]. - Antiretroviral drugs - Use of lipid lowering agents within 3 months prior to the pre-screening visit.
