5. Patients who, in the judgment of the Investigator, may be at risk for dehydration or volume depletion that may affect the patient's safety and/or the interpretation of efficacy or safety data.

6. Has evidence of current abuse of drugs or alcohol or a history of abuse within the past 52 weeks that, in the Investigator's opinion, would cause the individual to be noncompliant.

   Cardiovascular Conditions

7. Cardiovascular disease within 3 months of Screening (i.e., MI, cardiac surgery, revascularization, unstable angina, stroke, transient ischemic attack, or arrhythmia).

13. History of, or currently have, acute or chronic pancreatitis or have triglyceride concentrations ≥500 mg/dL at Visit 1 (Screening).
14. Suspicion that the patient is infected with an infectious substance according to World Health Organization risk categories A and B (see Appendix C).
15. Known severe hepatic disease, including chronic active hepatitis.

16. Positive serologic evidence of current infectious liver disease, including patients positive for hepatitis B viral antibody IgM, hepatitis B surface antigen, and hepatitis C virus antibody.

    Hematological/Oncological Conditions

17. Malignancy within 5 years of Visit 1 (Screening), with the exception of treated in situ basal cell or squamous cell carcinoma of the skin.
18. Hematocrit of <34% for both males and females. Prohibited Medications

20. Current treatment with potent cytochrome P450 3A4/5 inhibitors (e.g., atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin).
21. Administration of any other investigational drug or participation in any interventional clinical studies 30 days prior to Visit 1 (Screening).
22. Treatment with systemic corticosteroids for the last 3 months prior to Visit 1 (Screening).

23. Prescription or over-the-counter weight loss medications within 3 months prior to Visit 1 (Screening).

    Other
