| Outcome Measures: |
Primary: Subjects Experiencing Serious Adverse Events, Number of subjects reporting all-cause Serious Adverse Events (SAEs) for usual drug therapy plus Cycloset vs. that for usual drug therapy (UDT) plus placebo from baseline to week 52., From baseline to week 52. | Secondary: Number of Subjects Experiencing Serious Cardiovascular Adverse Events, The secondary safety endpoint is number subjects with occurrences of first cardiovascular SAE (myocardial infarction, stroke, in-patient hospitalization for heart failure, angina or revascularization surgery)., Baseline to week 52.|Change in HbA1c From Baseline to Week 24 in Subjects Failing Treatment With Metformin Plus a Sulfonylurea, Change in HbA1c from baseline to week 24 in subjects failing treatment with metformin plus a sulfonylurea with failure defined as having a baseline HbA1c value of ≥ 7.5%. Change was measured at week 24 after randomization in subjects having no major protocol violations. Change is reported as the absolute difference in % HbA1c., Baseline to week 24|Change in HbA1c From Baseline to Week 24 for Subjects With a Baseline HbA1c of ≥ 7.5% Who Were Taking at Least One Oral Hypoglycemia Agent (OHA) at Baseline., The difference between Cycloset and placebo in the change in HbA1c from baseline to Week 24 was analyzed for subjects with a baseline HbA1c of ≥ 7.5% who were taking at least one oral hypoglycemia agent (OHA) at baseline. The primary analysis was based on subjects from the evaluable per protocol efficacy (EPPE) analysis set with a secondary analysis using subjects from the intent to treat efficacy (ITTE) analysis set for subjects completing 24 weeks of treatment. Change is reported as the absolute difference in % HbA1c., Baseline to week 24
