Clinical Trial to Evaluate Efficacy and Safety of SID142 in Patients With Chronic Artery Occlusive Disease

September 18, 2019 updated by: SK Chemicals Co., Ltd.

A Multicenter, Randomized, Double-Blind, Active-Controlled, Parallel Group and Phase III Clinical Trial to Evaluate in Efficacy and Safety of SID142 in Patients With Chronic Artery Occlusive Disease

Rinexin® Tab (Cilostazol 100mg, Ginkgo biloba leaf extract 80mg) has been widely used as an anti-platelet agent for the treatment of PAD. SID142 is a new controlled-release product improved patient's convenience and disadvantage of dosage regimen of previous drug. The aim of this study was to compare the efficacy and safety of SID142 and Rinexin® Tab in patients with PAD

Detailed Description

This clinical trial is 12 weeks, multicenter, randomized, double-blind, parallel group, phase 3 study which registered patients in total 19 institutions appointed as national clinical trial institution, it was conducted by receiving IRB(institutional review board) approval from each institutions.

Target patients were aged over 20 years old male or female lower limb peripheral artery occlusion patients with fontaine stage II/III, who has lower limb pain. Lower limb pain degree is over 40 mm evaluated by VAS at screening, and ABI (ankle-brachial index) ≤0.9 or stenosis rate over >50%, diagnosed with PAD and voluntarily agreed to participate in clinical study and signed study consent form. Study subjects who met subjects criteria and recruited were total 170 subjects. Selected subjects were stratified by 1:1 ratio and randomly assigned to investigational product or comparator.

Investigational product was SID142 and comparator was Rinexin® Tab (Cilostazol 100mg, Ginkgo biloba leaf extract 80mg). Administration period to subjects was 12 weeks, study group took investigational product, SID1421 tab once(morning) and took placebo 1 tab/once, 2 times/day, and comparator group took investigational product, Rinexin® Tab 1 tab/once, 2 times/day and took placebo 1 tab once(morning).

Efficacy and Safety Assessment Parameter Subjects visited at 4, 8, and 12 weeks including baseline visit (visit 2) at 4 weeks interval and took efficacy and safety.

Variation in lower limb pain (VAS) comparing baseline with 12 weeks point as a primary efficacy Assessment parameter, variation in lower limb pain (VAS) comparing baseline with 4, 8 weeks, ankle brachial pressure index (ABI), ankle systolic pressure (ASP), Maximum Walking Distance (MWD), Pain Free Walking Distance (PFWD), andInvestigator's global assessment (5-point scale) as secondary efficacy assessment parameters, efficacy was measured. Pain and coldness test was measured using pain and coldness felt by subject 24 hours prior to the visit, MWD and PFWD was measured only on subjects who was determined to be possible to measure. Also, adverse event, laboratory test, vital sign, were conducted for safety assessment. Physical test and vital sign were conducted at screening visit, administration begins, 4, 8, and 12 weeks and urine pregnancy test and laboratory test were conducted at screening visits and 12 weeks. ECG test was conducted at screening visit, 4, 8, and 12 weeks after. Laboratory test criteria were hematological test, blood chemical test, blood coagulation test and urine test.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Variation in lower limb pain (VAS)
Time Frame: 12 weeks

A Visual Analogue Scale (VAS) is a measurement instrument that tries to measure lower limb pain that is believed to range across a continuum of values. The amount of pain that a subject feels ranges across a continuum from none to an extreme amount of pain.

VAS is a 100mm horizontal line. The patient marks on the line the point that they feel represents their perception of their state.

The VAS score is determined by measuring in millimetres from the left hand end of the line to the point that the subject marks. The higher the score, the more severe the pain.
