About this study

Official title: A comParison on Platelet Resistance With Ticagrelor or Standard-Dose Clopidogrel Study Among SeVerE Chronic Kidney Disease/ End-Stage-Renal-Disease Patients With Recent Acute Coronary Syndrome.

A 4 week-duration cross-over study on Ticagrelor and Clopidogrel for the Acute Coronary Syndrome (ACS) and Chronic Kidney Disease (CKD) subjects, focusing on the platelet inhibition and safety observation.

Read the detailed description

Acute coronary syndrome is a high mortality and costly disease. Antiplatelet therapies, including aspirin and P2Y12 antagonist, play important roles at the acute and subacute stage treatment for acute coronary syndrome, especially after coronary stent implantation. Patients with decreased estimated glomerular filtration rate (eGFR) experience higher cardiovascular morbidity and mortality. Clopidogrel, one of P2Y12 receptor antagonists, inhibits the receptor's activation by blocking its interaction with ADP. However, the efficacy of clopidogrel shows substantial variation and residual platelet reactivity, which is related to adverse cardiovascular outcome, especially in impaired renal function. Our study aims to check the platelet inhibition rate comparing both medication with a cross-over study among CKD subjects and ACS condition.

What is being measured

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

  1. platelet VerifyNow inhibition rate and Platelet Residual Unit (PRU) values changes

    Measured: baseline, 2 weeks and 4 weeks later (compare cross over effect)

Secondary outcomes (1)
  1. Major bleeding events

    assessed by TIMI bleeding score: mild, moderate and severe; the transfusion of packed red blood cell amount; decreased count in Hb (>2.5)

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Clopidogrel first and Ticagrelor first in people with Acute Coronary Syndrome and Chronic Kidney Disease, run by Ping-Yen Liu at 1 site in Taiwan.

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 7 inclusion and 5 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 2 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 Taiwan. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 Ping-Yen Liu, MD, PhD. (+88662353535 ext. 4602, larry@mail.ncku.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

platelet VerifyNow inhibition rate and Platelet Residual Unit (PRU) values changes (time frame: baseline, 2 weeks and 4 weeks later (compare cross over effect)). 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 NCT02459288, 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 2 Jun 2015.
