About this study

Official title: The Effect of Ticagrelor on Acute Coronary Syndrome Patients With Clopidogrel Resistance Undergoing Percutaneous Coronary Intervention

The purpose of this study is to compare the efficacy and safety of ticagrelor with clopidogrel

Read the detailed description

180 elective percutaneous coronary intervention patients with clopidogrel resistance were randomized to three groups, Group 1:received clopidogrel 75mg qd ;Group 2:received clopidogrel 150mg qd ; Group 3:received ticagrelor 90mg bid after PCI.Platelet funtion were tested by flowcytometric vasodilator-stimulated phosphoprotein(VASP) analysis before PCI,and 3days,7days and 1 month after PCI,respectively.The aim of our study is to compare the efficacy and safety of ticagrelor with clopidogrel

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. PRI

    Platelet funtion were tested by flowcytometric vasodilator-stimulated phosphoprotein(VASP) analysis.And a platelet reactivity index (PRI) was calculated.

    Measured: post operative 1 month

Secondary outcomes (2)
  1. Major adverse cardiac events(MACEs)

    cardiovascular death,angiographically confirmed stent thrombosis, recurrent acute coronary syndrome defined by the American College of Cardiology/American Heart Association guidelines,and recurrent revascularization by either coronary angioplasty or bypass surgery

    Measured: follow-up for 1 month

  2. major and minor bleeding

    Major bleeding was defined as intracranial bleeding or clinically-overt bleeding associated with a decrease in hemoglobin of 50 g/L, according to the Thrombolysis inMyocardial Infarction (TIMI) criteria .Minor bleeding was also defined according to TIMI criteria .

    Measured: follow-up for 1 month

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Clopidogrel and Ticagrelor in people with Acute Coronary Syndrome, run by General Hospital of Chinese Armed Police Forces at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 24 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact huiliang liu, doctor (86-10-57976531, lhl518@vip.sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PRI (time frame: post operative 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01812330, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2015.
