High-intensity Rosuvastatin vs. Moderate-intensity Rosuvastatin/Ezetimibe in High Atherosclerotic Cardiovascular Disease Risk Patients With Type 2 Diabetes

To assess the efficacy and safety of moderate-intensity rosuvastatin/ezetimibe compared to high-intensity rosuvastatin in high atherosclerotic cardiovascular disease risk patients with type 2 diabetes

This study is to assess the efficacy and safety of Rosuvamibe® (rosuvastatin 10mg/ezetimibe 10mg) vs. rosuvastatin 20mg treated for 24 weeks in atherosclerotic cardiovascular disease risk (≥ 7.5%) patients with type 2 diabetes

Eligibility Criteria:

* Body mass index (BMI) ≤ 35kg/m2 in screening
* Female of childbearing with a negative pregnancy test who must agree to use contraception (including those not medically pregnant) during the study period
* Written consent after being informed of the purpose and contents of the clinical trial and the characteristics and risks of IPs

Exclusion Criteria:

* Estimated GFR \< 30mL/min/1.73m2 using the CKD-EPI formula in screening
* Undergoing renal replacement therapy (hemodialysis or peritoneal dialysis) in screening
* Having used other statin (HMG-CoA converting enzyme inhibitors) than Rosuvastatin or fibrate drugs in the last 3 months before screening
* Taking any medication (ex. Fenofibrate, Omega 3 fatty acid, etc.) that may affect LDL

  * Uncontrolled diabetes (HbA1c ≥ 10%)
  * Uncontrolled thyroid dysfunction (TSH ≥ 3 x ULN)
* Subjects with a medical history of acute arterial diseases such as unstable angina, myocardial infarction, transient ischemic attack, cerebrovascular disease, coronary artery bypass graft or percutaneous coronary intervention in the last 6 months before screening
* Subjects with a surgical history of gastrointestine or drug absorption disorders due to gastrointestinal disorders
* Insulin-treated
* Taking other IPs in the last 30 days before screening
* Subjects who cannot discontinue contraindications that may affect the treatment of all types of diabetes and/or hypercholesterolemia during the study period
* Subjects with a significant or unstable medical or psychological condition that is judged by investigator to be detrimental to safety or to successful participation in the trial
* Other conditions than the above who is deemed to be ineligible to participate in the trial by investigator
