Eligibility Criteria
Criteria
-
Males
-
Age 18-65 inclusive
-
Established T2DM for ≥ 1 year
-
Taking stable doses (≤ 20% change in total daily insulin dose within 2 months prior to screening) of basal insulin, with or without prandial insulin (total daily dose must be ≤ 200 units)
-
Baseline hemoglobin A1c (HbA1c) 8.0%-10.5%
-
No use of any anti-hyperglycemic agents (oral or injectable) other than metformin or insulin
-
No history or clinical suspicion of type 1 diabetes mellitus
-
No concurrent chronic use of any corticosteroids by any route and for any indication, or concurrent conditions that may require the initiation of glucocorticoids during the study
-
No concurrent lipid-lowering medications whose levels are dependent on CYP3A pathway clearance (e.g., simvastatin, lovastatin, atorvastatin, fluvastatin and rosuvastatin) should either be washed out for at least one month prior to enrollment and/or switched to alternative LDL-cholesterol lowering agents (e.g., pravastatin or ezetimibe) for at least one month.
-
No contraindications or known intolerance to mifepristone
-
No concurrent use of strong CYP3A inhibitors (e.g., cyclosporine, ergotamine, fentanyl, quinidine, sirolimus, tacrolimus, imidazole antifungals, HIV protease inhibitors, certain macrolide antibiotics)
-
No concurrent use of CYP3A inducers (e.g., phenytoin, phenobarbital, carbamazepine, rifampin)
-
No concurrent use of medications that may prolong the QT interval (e.g., selected antipsychotics and antidepressants, quinolone antibiotics)
-
No daily use of warfarin or non-steroidal anti-inflammatory agents
-
Baseline K+ and Mg+2 within the laboratory normal ranges, with or without oral K+ and/or Mg+2 supplementation
-
Fasting plasma glucose (FPG) averaging < 280 mg/dL and without polyuria or polydipsia
-
No symptomatic hypoglycemia averaging > once per day
-
Able and willing to perform self-monitoring of blood glucose (SMBG)
-
Mean BP < 140 mmHg systolic or 90 mm Hg diastolic
-
Baseline LDL-cholesterol < 200 mg/dL if on lipid-lowering therapy or < 250 mg/dL while not on lipid-lowering therapy
-
Fasting triglycerides ≤ 500 mg/dL if on lipid-lowering therapy
-
HDL-cholesterol ≥ 25 mg/dL
-
No known history of prostate cancer, or elevated level of prostate-specific antigen (PSA) at screening
-
Estimated GFR ≥ 30 mL/min
-
No concurrent endocrinopathies that have not been stabilized with replacement or other definitive therapies (including known adrenal insufficiency regardless of replacement therapy, cortisol < 5 μg/dL at screening)
-
No active hemolytic anemias or hemoglobin variants that render the measurement of HbA1c potentially unreliable
-
No other clinically significant hepatic, cardiovascular (including known personal or family history of, or risk factors for long-QT syndrome, QTcF prolongation on ECG > 500 ms), infectious (including HIV or any viral hepatitis), inflammatory, neoplastic or other systemic disease that may contraindicate the change of lipid-lowering therapy, renders mifepristone unsafe, or otherwise confounds data interpretation
-
Subjects not likely to start other drugs that may influence the study's outcomes (e.g., weight loss agents)
-
Subjects who are able and willing to comply with all components of the study protocol, attend all scheduled follow-up visits, or who do not present other foreseeable barriers that might make the implementation of the protocol problematic or confound data interpretation
