Strokes not known to be hemorrhagic will be allowed as part of this criterion; * Occlusion and stenosis of carotid artery without mention of cerebral infarction as History of carotid arterial disease as documented by ≥50% stenosis documented by carotid ultrasound, magnetic resonance imaging (MRI), or angiography, with or without symptoms of neurologic deficit * Peripheral arterial stenting or surgical revascularization, Lower extremity amputation, and Ankle brachial pressue index \<0.9 as: Atherosclerotic peripheral arterial disease, as documented by objective evidence such as amputation due to vascular disease, current symptoms of intermittent claudication confirmed by an anklebrachial pressure index or toe brachial pressure index less than 0.9, or history of surgical or percutaneous revascularization procedure. * Encounter for contraceptive management and oral contraceptives as Female patients agree to use an effective method of contraception or must not otherwise be at risk of becoming pregnant. Exclusion Criteria: * Patient has a history of type 1 diabetes mellitus or a history of ketoacidosis. * Patient has a history of ≥2 episodes of severe hypoglycemia during the 12 months prior to enrollment.
