a study of ly2409021 in patients with type 2 diabetes

Conditions: Diabetes Mellitus, Type 2

Summary: ly2409021 is being evaluated for possible treatment in type 2 diabetes. this study is designed to compare ly2409021 given alone or given in combination with metformin against placebo the change in hemoglobin a1c after a 24-week treatment period.

aspartate aminotransferase \[ast\] or alanine aminotransferase \[alt\]) greater than 2.5 times upper limit of normal (uln) as determined by the central laboratory at screening. * have a current or previous diagnosis of gilbert's disease. * have previous or current diagnosis of hepatitis b or c * have a serum creatinine \>2 milligrams per deciliter (mg/dl) or, in patients being treated with metformin, a serum creatinine above (or creatinine clearance below) what is approved in the metformin product labeling in the respective country. * show evidence of uncorrected hypothyroidism or hyperthyroidism based on clinical evaluation and/or an abnormal thyroid stimulating hormone result as determined by the central laboratory at screening; patients receiving dose-stable thyroid replacement therapy for at least 3 months prior to screening will be allowed to participate in the study. * have any other abnormal laboratory value that, in the opinion of the investigator, precludes the patient from participation in the study. laboratory abnormalities consistent with type 2 diabetes mellitus and all other eligibility criteria are acceptable: for example, abnormalities of blood glucose, hemoglobin a1c (hba1c), urinary glucose, and urinary protein (with a range of trace to 1+ on dipstick). * have a currently suspected or treated malignancy, or are in remission from a clinically significant malignancy (other than basal or squamous cell skin cancer, in situ carcinomas of the cervix, or in situ prostate cancer) for less than 5 years. * have a personal or family history of pancreatic neoplasia. * have non-fasting triglycerides \>600 mg/dl. * use or have used insulin or glp-1 agonists (for more than 1 week within the 3-month period prior to screening), or any oral antihyperglycemic medication (oam) other than metformin within the 3-month period prior to screening. * currently use or intend to use prescription or over-the-counter medications, including herbal supplements, to promote weight loss or to regulate blood glucose. * have current chronic (\>2 weeks) systemic glucocorticoid therapy (excluding ocular topical, other topical, inhaled preparations) or have received such therapy within 8 weeks prior to screening. * currently use hyperglycemia-causing agents, hypoglycemia-causing agents (other than metformin), class ii and iii antiarrythmic agents, agents that reduce gastrointestinal motility, central nervous system stimulants (with the exception of caffeinated beverages), fibrates, and niacin greater than or equal to 1 grams per day (gm/day). * have an average weekly alcohol intake that exceeds 2 units per day for males and 1 unit per day for females (1 unit = 12 ounces (oz) or 360 ml of beer; 5 oz or 150 milliliters (ml) of wine; 1.5 oz or 45 milliliter (ml) of distilled spirits). * currently use drugs with a narrow therapeutic index (for example, digoxin, lithium, phenytoin, theophylline, and warfarin). * currently use drugs that are known to prolong the qt interval. * currently use or intend to use potent inhibitors of cyp3a, which include but are not limited to atazanavir, indinavir, nelfinavir, ritonavir, clarithromycin, itraconazole, ketoconazole, nefazodone, saquinavir, and telithromycin. * have previously completed or withdrawn from this study or any other study investigating ly2409021. * have known allergies to ly2409021 or related compounds. * are currently enrolled in, or discontinued within the last 30 days from, a clinical trial involving an investigational product or unapproved use of a drug or device, or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study * have any other condition such as alcohol abuse, drug abuse, or psychiatric disorder that may affect the ability to participate in the trial.
