Clinical Trial Summary

The clinical trial aims to confirm the improvement effect of the ankle brachial index and the safety of sarpogrelate administration compared to clopidogrel in stroke patients with decreased ankle brachial arterial pressure index and intermittent claudication of lower limb vascular atherosclerosis. Subjects are assigned to one of the two combinations through random allocation. Intervention group: Aspirin 100mg + sarpogrelate 300mg dosing group, Control group: Aspirin 100mg + clopidogrel 75mg dosing group. This clinical trial is a prospective open study and will be conducted in compliance with the usual diagnosis and treatment process, and in particular, all trial subjects will be tested and treated appropriately in accordance with the standard treatment guidelines for ischemic stroke during the clinical trial period.


Description:

A total of 100 subjects are recruited and divided into a intervention group and a control group through randomization. In this clinical trial, the intervention group and the control group are assigned 1:1. The researcher allocates 1:1 to the intervention group or control group through a two-way random number table on the assignment date in the order of the subjects who are satisfied with the Inclusion and exclusion criteria and agreed to the study. This study is a prospective open randomized clinical trial that can confirm which group the subjects themselves were assigned to. After randomization, the drug is prescribed and the outcome variable is checked at 12 months. During the course of the clinical trial, the examiner and researchers carefully observe the presence or absence of adverse events during the follow-up period after randomization, and closely observe outcome variables, including neurological changes. Visit after 6 months and 12 months during the clinical trial period to confirm the effectiveness and safety. When an event corresponding to the outcome variable occurs, the researcher first plans to implement appropriate medical measures in this regard. Both groups will be conducted in compliance with the usual diagnosis and treatment process, and in particular, all subjects will be tested and treated appropriately according to the standard treatment guidelines for ischemic stroke during the clinical trial period. The purpose of this study is to determine whether there is a difference in the improvement and safety of the ankle-brachial arterial pressure index of aspirin+sarpogrelate and aspirin+clopidogrel in stroke patients with decreased ankle-brachial arterial pressure index and intermittent claudication.

Outcome

Type Measure Description Time frame Safety issue
Primary Ankle brachial index The value of the ankle brachial index evaluated 12 months after the first dose of the clinical trial drug. Ankle brachial index : normal range > 0.9, abnormal range < 0.9 Baseline, 12months
Secondary Ankle brachial index The value of the ankle brachial index evaluated 6 months after the first dose of the clinical trial drug. Ankle brachial index : normal range > 0.9, abnormal range < 0.9 Baseline, 6months
Secondary Brachial ankle pulse wave velocity The value of Brachial ankle pulse wave velocity evaluated 6 months and 12months after the first dose of the clinical trial drug. Brachial ankle pulse wave velocity : normal range 1000~1500 cm/sec, abnormal range > 1600 cm/sec Baseline, 6months, 12months
Secondary Major cardio-cerebrovascular events Major cardio-cerebrovascular events that occurred within 6 months and 12 months after the first medication related to the clinical trial. (Stroke, myocardial infarction, non-stable angina, lower limb vascular intervention, surgery, death) Baseline, 6months, 12months
Secondary Lower limb angioplasty or re-operation Whether or not to perform lower limb angioplasty or re-operation, evaluated 6 months and 12 months after the first dose of the clinical trial drug. Baseline, 6months, 12months
Secondary Change of Rutherford category ratio Change of Rutherford category ratio, a symptom scale related to vascular stenosis of the lower extremities, evaluated 6 months and 12 months after the first dose of the clinical trial drug. (Grade 0-Asymptomatic, Grade 1-Mild claudication, Grade 2-Moderate claudication, Grade 3-Severe claudication, Grade 4-Ischemic rest pain, Grade 5-Minor tissue loss-nonhealing ulcer, focal gangrene with diffuse pedal ischemia, Grade 6-Major tissue loss-extending above transmetatarsal level, functional foot no longer salvageable) Baseline, 6months, 12months
Secondary Modified Rankin scale Modified Rankin scale evaluated 6 months and 12 months after the first dose of the clinical trial drug. (0-No symptoms at all, 1-No significant disability despite symptoms; able to carry out all usual duties and activities, 2-Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance, 3-Moderate disability; requiring some help, but able to walk without assistance, 4-Moderate to severe disability; unable to walk without assistance, and unable to attend to own bodily needs without assistance, 5-Severe disability; bedridden, incontinent and requiring constant nursing care and attention, 6-Death) Baseline, 6months, 12months
Secondary National Institutes of Health Stroke Scale Changes in NIHSS evaluated at 6 months and 12 months after the first dose of the clinical trial drug. National Institutes of Health Stroke Scale score of 0 (lowest point) means normal, and a score of 42 (high point) means severe dysfunction caused by stroke, so the higher the score, the more severe the stroke.
