A subject may be included in this study if he/she meets all of the following criteria:

1. Male or female, age 18 to 75
2. Females of childbearing potential (intact uterus and within 1 year since the last menstrual period) should be non-lactating and have a negative serum pregnancy test. In addition, these subjects should agree to use the following acceptable birth control methods beginning at the Screening Visit and throughout the study:

1. abstinence
2. surgical sterilization (bilateral tubal ligation, hysterectomy, bilateral oophorectomy) 6 months minimum
3. IUD in place for at least 3 months
4. barrier methods (condom or diaphragm) with spermicide
5. surgical sterilization of the partner (vasectomy for 6 months)
6. hormonal contraceptives for at least 3 months prior to the first dose
3. Diagnosis of type 2 diabetes mellitus (DM) for at least 6 months.
4. Type 2 diabetes may be treated only with metformin (metformin hydrochloride tablets or metformin hydrochloride extended-release tablets) at a total daily dose of 500 mg to the maximum labeled dose. (See Appendix G for List of Drug Trade Names).The dose of metformin must be stable for >8 weeks prior to the Pre-Treatment Visit (Week -4) and throughout the course of the study. The subject must not be on any other pharmacologic or over-the-counter treatments for diabetes.

6. Fasting C-peptide level of >0.33 nmol/l (1.0 ng/ml)
7. ACTH stimulation test results with any cortisol level of >18 µg/dl at baseline or 60 minutes
8. Normal complete blood count (CBC) with platelets and differential
9. 12-lead electrocardiogram (ECG) shows no acute ischemia or clinically significant abnormality. Subjects with QTc interval of >450 msec will be excluded from the study.
10. BMI of 27 to 42 kg/m2 (see Appendix B)

* A subject may be excluded from this study if he/she meets any of the following criteria:

1. Previous participation in a clinical trial with DIO-902.
2. History of any atherosclerotic disorder (myocardial infarction, unstable angina, cerebrovascular accident, peripheral vascular disease or congestive heart failure secondary to ischemic myocardial injury) that would, in the estimation of the Investigator, make it unsafe to stop all lipid lowering drugs for up to 12 weeks during the course of the study.
3. Known hypersensitivity or idiosyncratic reaction related to ketoconazole or other imidazole compounds.
4. History of malignancy (except basal cell carcinoma) within the 3 years before the initial dose of the study medication.
5. Excessive alcohol intake (>20 g per day for females (1.5 standard alcohol drinks) or >30 g per day for males (2.0 standard alcohol drinks) (a standard drink contains 14 g of alcohol: 12 oz of beer, 5 oz of wine or 1.5 oz of spirits) or drug abuse. (1.0 fluid oz (US) = 29.57 ml)
6. Any other clinically significant medical condition, as determined by the Investigator. These clinically significant medical conditions include, but are not limited to, uncontrolled hypertension, NYHA class III or IV CHF, proliferative diabetic retinopathy and neuropathic symptoms that limit activities of daily living.
7. Participation in another clinical trial and/or treatment received with any investigational agent within one month before the initial dose of study medication.
8. Concomitant therapy with the following: (See Appendix G for List of Drug Trade Names)

1. weight loss medications
2. oral or injected hypoglycemics (metformin is allowed) or insulin
3. oral, parenteral or inhaled steroids; nasal, topical ocular, intravitreal, and low to moderate potency topical steroids are allowed
4. dihydropyridine calcium channel blockers (amlodipine, diltiazem and verapamil are allowed)
5. H2 antagonists and proton pump inhibitors (liquid and tablet antacids are allowed)
6. midazolam, triazolam, alprazolam, terfenadine, astemizole, digoxin, coumarin derivatives, phenytoin, rifampin, HIV protease inhibitors, spironolactone, aliskiren, erythromycin or clarithromycin, cyclosporine or tacrolimus
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
