An Ascending Multi-Dose, Tolerance and Pharmacokinetic Study in Obese or Overweight Type 2 Diabetic Volunteers

Different amounts of trodusquemine (MSI-1436) will be given to each volunteer group throughout the study. Another purpose is to evaluate the pharmacokinetics (PK - the study of the way the drug enters and leaves the blood and tissues over time) of trodusquemine (MSI-1436). Finally, this study will also determine whether trodusquemine (MSI-1436) has any effect on appetite, mood or behavior, and selective biomarkers (substances in your blood that may change in response to the study drug).

• of any race who are in good health (based on medical history, physical examination, electrocardiograms [ECGs], and clinical laboratory tests);
• non-smokers (refrained from any tobacco or nicotine usage, including smokeless tobacco, nicotine patches, etc.,) for 6 months prior to Day 0 of the study. Subjects must have cotinine levels below those measured for smokers based on reference lab values;
• body mass index (BMI) of 27-40 kg/m2;
• able to execute informed written consent;
• willingness to remain in the clinic for the inpatient portion of the study and return for follow-up visits as required by the protocol and as deemed necessary by the Principal Investigator;

Subjects with an abnormal serum creatinine should not be enrolled. Subjects with AST (SGOT), ALT (SGPT), GGT, alkaline phosphatase, bilirubin, blood urea nitrogen (BUN), prothrombin time (PT), or activated partial thromboplastin time (aPPT) >1.5 times above the upper limit of normal should not be enrolled;
• any subject with a clinically significant mental or physical illness within 1 year prior to the first dose, including a history of alcohol and/or drug abuse within 1 year prior to the first dose of study medication;
• Insulin requiring diabetics;
• any subject who has received any known hepatic or renal clearance altering agents (eg, erythromycin, cimetidine, barbiturates, phenothiazines, St. John's Wort, etc.) within a period of 90 days prior to the first dose of study medication;
• any subject who has received any approved prescription anti-obesity drug or has taken any over-the-counter medication for weight loss or who has received a thiazolidinedione or exanatide within a period of 90 days prior to the first dose of study medication;
• ingestion or use of any investigational medication or device within 60 days prior to the first dose of study medication; ingestion or use of any investigational anti-obesity medication is prohibited within 3 months prior to the first dose of study medication;
• any subject with history of malignancy in last 5 years, with exception of basal and squamous cell carcinomas of the skin;

• a positive qualitative urine drug or alcohol test at screening or at check-in;
• mental capacity is limited to the extent that the subject cannot provide legal consent or understand information regarding the study;
• any subject who has had a 10% weight loss in the past 3 months prior to the screening visit.
