Criteria

Inclusion Criteria:

1. Male or Female outpatients between 40 and 75 years of age,

2. Patients confirmed to have symptoms of peripheral arterial disease (including intermittent claudication, pain, coldness and fatigue) in the lower extremities,

3. Patients who have a steady symptom without significant improvement within 12 weeks prior to screening visit and whose PAQ score of the question number 3 is 3 or less at enrollment visit,

4. Ankle Branchial Index (ABI) ≤0.90 when measuring the pressure in a supine position after resting for 10 minutes,

5. Patients who are equal to or less than 10% of the difference in PAQ summary scores at between screening and enrollment,

6. Patients who have been fully explained about this study, voluntarily decided to participate in this study, and provided written informed consent.

Exclusion Criteria:

1. Patients with ischemic pain at rest or having ischemic ulcer or gangrene,

2. Patients with Ankle Branchial Index (ABI) ≤ 0.40

3. Patients who underwent sympathectomy or lower extremity arterial reparative surgery including endovascular procedures within 12 weeks prior to screening visit,

4. Patients diagnosed of deep vein thrombosis within 12 weeks prior to screening visit, (provided that patients with isolated calf vein thrombosis may be enrolled)

5. Patients with the following disease:

• Patients who is on or needs the treatment for Congestive heart failure

• Myocardial infarction which occurred within 24 weeks prior to screening visit

• Patients who is on or needs the treatment for unstable angina pectoris,

6. Patients with hemorrhage (hemophilia, capillary fragility, intracranial hemorrhage, upper gastrointestinal hemorrhage, urinary hemorrhage, hemoptysis, vitreous hemorrhage, etc.) and predisposition to hemorrhage (active peptic ulcer, hemorrhagic stroke within the recent 24 weeks, suspected hemorrhage when administering cilostazol for wound due to surgery within the recent 12 weeks, and proliferative diabetic retinopathy),

7. PT, aPTT level greater than 1.5 times the upper limit of normal at screening visit,

8. Uncontrolled hypertension defined as ≥ 160 mmHg of systolic blood pressure or ≥ 100 mmHg of diastolic blood pressure,

9. Creatinine clearance(Ccr)a ≤ 25mL/min at screening a. Creatinine clearance (Ccr) is calculated by the following modified Cockcroft-Gault formula using the serum creatinine as determined by the site laboratory.

Ccr(mL/min)=[260-age(year)] x Body weight(kg) / 160 x Serum creatinine(mg/dL) (male) Ccr(mL/min)=[236-age(year)] x Body weight(kg) / 180 x Serum creatinine(mg/dL) (female), 10) AST or ALT level greater than 3 times the upper limit of normal at screening, 11) Total bilirubin level greater than 2 times the upper limit of normal at screening, 12) Type 1 diabetes mellitus or uncontrolled type 2 diabetes mellitus (HbA1c greater than 9%), 13) Patients determined ineligible to participate in this clinical trial at the discretion of Investigator due to critical diabetic complications (diabetic foot ulcer, foot deformity, etc.), 14) Female patients whose serum pregnancy test at screening or urine pregnancy test at enrollment is positive in case of childbearing potential and breastfeeding women,

• For female patients, those who have been at their postmenopause at least for one year or longer, who have no potential to be pregnant by surgery or procedure, or who agreed to use acceptable contraceptive methods (intrauterine device [loop or Mirena], double barrier method [diaphragm or condom/femidom + spermicide], vasectomy in spouse, oral contraceptives or non-oral contraceptives) throughout the entire study period,Female patients whose pregnancy test at screening is positive in case of childbearing potential or breastfeeding women 15) History of malignant disease (excluding treated basal cell or squamous cell carcinoma of skin) within 5 years prior to Screening. Resolution of a prior malignancy more than 5 years prior to Screening must be deemed as cured by the investigator, 16) Patients who have history of taking or plan to take the following medications:

• Cilostazol-containing medications within 12 weeks prior to screening visit,

• Antiplatelets (such as aspirin and ticlopidine), anticoagulants (such as warfarin), thrombolytics (such as urokinase and alteplase), prostaglandin E1 and its derivatives (such as alprostadil and limaprost), pentoxyfylline, beraprost, sarpogrelate and statin within 4 weeks prior to screening visit. However, aspirin (≤ 100 mg) or statin being taken for more than 4 weeks prior to screening visit may be administered at the same dose.

• Nitrates, papaverine, isoxsuprine, and NSAIDs within 4 weeks prior to screening visit. However, NSAIDs being taken for more than 4 weeks prior to screening visit may be administered at the same dose, 17) Patients with a history of hypersensitivity to cilostazol, 18) Patients who have received an investigational product or biological agent within 12 weeks prior to screening visit, 19) Patients who plans to enroll in another clinical trial (excluding observational studies) during this study, 20) Patients who needs to stop the Investigational Product because of scheduled operation, extraction of tooth or endoscopy, 21) Patients who are otherwise judged by the investigator to be inappropriate for inclusion in the study.
