8. Concomitant therapy with the following: (See Appendix G for List of Drug Trade Names)

7. Subjects currently taking lipid lowering medications may be enrolled if the Investigator determines that the subject does not have any conditions that preclude cessation of lipid lowering treatment for up to 12 weeks. [All subjects will be required to discontinue all lipid lowering therapies during the 4 week Pre-Treatment Period and will then be randomized to receive either atorvastatin 10 mg or atorvastatin placebo during the first 8 weeks of the Treatment Period. All subjects will then receive atorvastatin 10 mg during weeks 8 to 16 of the Treatment Period.] Subjects may not be on any other lipid lowering agent through Visit 7 (Week 20) of the study.
9. History of HIV
10. Positive hepatitis B (HbsAg) or positive hepatitis C (Hepatitis C antibody) test during Screening
11. Liver function tests must not be above the following cut-offs: ALT and/or AST >3.0X ULN, AP >1.5X ULN and total bilirubin >ULN. (If all LFTs are WNL and total bilirubin is elevated, a retest of direct and indirect bilirubin may be performed. Subjects with indirect total bilirubin up to 3X ULN (presumed Gilbert's syndrome) may be enrolled if all other LFTs are WNL.)
12. CK must not be >2.5X ULN if not clearly related to recent exercise, injury or unusual activity
13. Creatinine must not be >1.4 mg/dl in females and >1.5 mg/dl in males.
14. Thyroid stimulating hormone level >1.5X ULN
15. History of lactic acidosis
16. Known hypersensitivity to cosyntropin (ACTH) or any component of the formulation (mannitol or sodium chloride)
17. Known intolerance to statin drugs
18. Any other condition which increases the risk of participation in the trial in the opinion of the investigator

Summary
Brief summary
DiObex Inc. is developing an experimental drug (DIO-902) that is made up of part of the ketoconazole molecule for the treatment of elevated blood glucose associated with type 2 diabetes mellitus. Ketoconazole (Nizoral®) is a drug available by prescription for the treatment of fungal infections however DIO-902 is an investigational drug. DIO-902 may lower blood glucose by lowering levels of a naturally occurring hormone called cortisol. Elevated cortisol may contribute to the development of type 2 diabetes.

The purpose of this research study is to test the safety of DIO-902 when taken by mouth with metformin and the cholesterol-lowering drug atorvastatin to determine the type and severity of any side effects from this treatment.

Other purposes of the study are to see how the treatment affects your blood glucose levels, cholesterol levels, blood pressure, and waist circumference.
