About this study

Official title: Ticagrelor Versus High-dose Clopidogrel in Patients With High Platelet Reactivity on Clopidogrel After Percutaneous Coronary Intervention: The PL-PLATELET Randomized Trial

To determine the safety and efficacy of Ticagrelor versus Clopidogrel for the reduction of adverse cardiovascular outcomes in patients with high platelet reactivity on clopidogrel after successful implantation of coronary drug-eluting stents.

Read the detailed description

This is a multi-center, randomized, single-blind, investigator-initiated study with a parallel design. Patients with coronary artery disease undergoing percutaneous coronary intervention and presenting high platelet reactivity on clopidogrel as assessed with the PL-11 analyzer (platelet maximum aggregation ratio [MAR%] ≥ 55 %) at 2 hours post-clopidogrel 300mg LD (Day 0), will be randomized after informed consent, in a 1:1 ratio to the following treatment groups:

Group Α: Ticagrelor 180 mg immediate loading (on Day 0) followed by 180mg/day starting from Day 1 until Day 365 (12 months after randomization).

Group Β: Clopidogrel 150mg per day, starting from Day 1 until Day 365 (12 months after randomization).

Platelet reactivity assessment will be performed before randomization (Day 0), and 3-day after randomization (Day 3). Documentation of major adverse cardiac and cerebrovascular events (death, myocardial infarction, stent thrombosis, stroke, revascularization procedure with PCI or CABG) and serious adverse events (bleeding, other adverse events) will be performed until 12 months.

What is being measured

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

  1. 12-Month Freedom From MACE

    Major adverse cardiovascular and cerebrovascular events consist of all-cause death, target vessel myocardial infarction, stroke, stent thrombosis.

    Measured: 12 months

Secondary outcomes (7)
  1. 12-Month Freedom From Mortality

    All-cause death

    Measured: 12 months

  2. 12-Month Freedom From Cardiac death

    Cardiac death

    Measured: 12 months

  3. 12-Month Freedom From MI

    Myocardial infarction

    Measured: 12 months

  4. 12-Month Freedom From TLR

    Target lesion revascularisation

    Measured: 12 months

  5. 12-Month Freedom From TVR

    Target vessel revascularisation

    Measured: 12 months

  6. 12-Month Freedom From Stent Thrombosis

    Stent thrombus was classified as definite, probable, or possible, according to the definitions provided by the Academic Research Consortium (ARC).Regarding timing, ST was defined as early (<30 days), late (30 days to 1 year), or too late (>1 year).

    Measured: 12 months

  7. 12-Month Freedom From Stroke

    Stroke

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ticagrelor and Clopidogrel in people with Coronary Artery Disease, run by Nanjing First Hospital, Nanjing Medical University 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 2 inclusion and 7 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: withdrawn, as of the sponsor's last update on 19 Aug 2021. 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?

The study was withdrawn before enrolling participants, so there are no results.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

12-Month Freedom From MACE (time frame: 12 months). 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 NCT03078465, which also lists 1 linked publication.

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 19 Aug 2021.
