November 18, 2015 updated by: Myeong-Ho Yoon, Ajou University School of Medicine

A Comparative Evaluation of Efficacy and Safety in the 3-Months DAPT Group vs. the 6-Months DAPT Group of Patients Treated With the Coroflex ISAR Stent; A Prospective, Multicenter, Randomized, Open-Label Clinical Trial

This clinical trial studies patients treated with the Coroflex ISAR Stent for coronary artery disease in order for the objective of verifying the non-inferiority of results that among patients who were administered DAPT for 3 months compared to patients who were administered DAPT for 6 months, in terms of the efficacy and safety of DAPT.

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
MACE
Time Frame: 12 months from the time of the stenting
Major Adverse Cardiac Events (MACE) (cardiac death, recurrent myocardial infarction, target lesion revascularization) at 12 months from the time of the procedure
12 months from the time of the stenting

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
