STOPping Versus Continuing Antiplatelet Therapy During Noncardiac Surgery and Procedures After Next Generation Drug-eluting Stent Implantation

May 17, 2018 updated by: Yonsei University

Randomized Controlled Comparison: STOPping Versus Continuing Antiplatelet Therapy During Noncardiac Surgery and Procedures After Next Generation Drug-eluting Stent Implantation (STOP-ASP Trial)

Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Most current guidelines recommend to focus on continuing antiplatelet therapy (mostly with aspirin) during noncardiac surgery if possible. Although previous study showed efficacy of continuous antiplatelet therapy in reducing perioperative ischemic cardiovascular events, its effectiveness is still not clear between perioperative bleeding and ischemic risk. Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).

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.

Ages Eligible for Study

19 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Continuing aspirin
Patients in the group may continue the administration of aspirin during perioperative period.
Drug: Continuing aspirin
Subject assigned to control arm will maintain antiplatelet therapy using aspirin only at least 7 days before surgery. If subject is taking one or more antiplatelet drugs, it should be changed (for subjects taking antiplatelet drug except aspirin at enrollment) or continued (for subject taking aspirin at enrollment) with low-dose, aspirin monotherapy before surgery. Cessation of clopidogrel, ticagrelor, and prasugrel should be started at least 5 days, 3 days and 7 days before surgery, respectively. Administration of aspirin will be started at the day of cessation of previous antiplatelet regimen and maintained until third postoperative day with 100 mg once a day.
Experimental: Stopping aspirin
Patients in the group may stop medication of antiplatelet drugs during perioperative period.
Drug: Stopping aspirin
Subject assigned to comparison arm will stop antiplatelet therapy before scheduled surgery or procedure. If subject is taking aspirin, clopidogrel, ticagrelor, or prasugrel, it should be discontinued for 7 days, 5 days, 3-5 days, and 7 days before surgery. Antiplatelet therapy may be restarted as previous regimen at fourth postoperative day or sooner unless significant bleeding risk or bleeding event occurs.
