Trial summary

It is general that there are many factors for individual differences of drugs in clinical application, of which genetic factors accounted for more than 20%. Ticagrelor is a new-type receptor antagonist of P2Y12 and it is not affected by the influence of CYP2C19 polymorphism. Read more about this study

About this study

It is general that there are many factors for individual differences of drugs in clinical application, of which genetic factors accounted for more than 20%. Ticagrelor is a new-type receptor antagonist of P2Y12 and it is not affected by the influence of CYP2C19 polymorphism. With lack of predicted biomarkers, especially the research data of Chinese, it has the important significance in studying individual differences of ticagrelor in the antiplatelet efficacy and safety, through the pharmacogenomics research.

The aim of this study is to determine the polymorphism of drug metabolizing enzymes, drug transporters and drug target genes in Chinese population. By detecting the gene polymorphism, we intend to study the pharmacokinetic/ pharmacodynamics/ pharmacogenomics (PK-PD-PG) correlation of ticagrelor and provide scientific basis for accurate medication guide for people to use ticagrelor.

What is being measured

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

  1. Incidence of major adverse cardiac events (MACE)

    During the observation time, record the incidence of MACE after ticagrelor administration by telephone or outpatient clinic , including myocardial infarction, cardiac death, stent stenosis, stent thrombosis, ect.

    Measured: At 1 year

  2. Incidence of bleeding events

    During the observation time, record the incidence of bleeding events after ticagrelor administration by telephone or outpatient clinic, including subcutaneous bleeding, gingival bleeding, gastrointestinal bleeding, intracranial hemorrhage, etc.

    Measured: At 1 year

Secondary outcomes (8)
  1. genotype detected by next generation sequencing

    Collect blood specimen before ticagrelor administration, then detect genotype of Ticagrelor by next generation sequencing.

    Measured: pre-dose of Ticagrelor

  2. Level of platelet reactivity assessed by ADP aggregation rate

    Before and after ticagrelor administration, record the ADP aggregation rate detected by Light Transmittance Aggregometry(LTA).

    Measured: At baseline, at 12 hours for Chinese healthy volunteers or at 48 hours for Chinese patients.

  3. Level of platelet reactivity assessed by PRI

    Before and after ticagrelor administration, record PRI detected by VerifyNow System.

    Measured: At baseline, at 12 hours for Chinese healthy volunteers or at 48 hours for Chinese patients.

  4. Expression level of miRNA

    Before and after ticagrelor administration, detect the expression level of miRNA about pharmacodynamics.

    Measured: At baseline, at 12 hours for Chinese healthy volunteers or at 48 hours for Chinese patients.

  5. Expression level of proteomics

    Before and after ticagrelor administration, detect the expression level of proteomics about pharmacodynamics

    Measured: At baseline, at 12 hours for Chinese healthy volunteers or at 48 hours for Chinese patients

  6. Expression level of LncRNA

    Before and after ticagrelor administration, detect the expression level of LncRNA about pharmacodynamics.

    Measured: At baseline, at 12 hours for Chinese healthy volunteers;at 48 hours for Chinese patients.

  7. Incidence of MACEs in the other observation times

    During the other observation time, record the incidence of MACE after ticagrelor administration by telephone or outpatient clinic , including myocardial infarction, cardiac death, stent stenosis, stent thrombosis, ect.

    Measured: At 1 month, 6 months and 2 years (according the actual duration of ticagrelor taken in patiens)

  8. Incidence of bleeding events in the other observation times

    During the other observation time, record the incidence of bleeding events after ticagrelor administration by telephone or outpatient clinic, including subcutaneous bleeding, gingival bleeding, gastrointestinal bleeding, intracranial hemorrhage, etc.

    Measured: At 1 month, 6 months and 2 years (according the actual duration of ticagrelor taken in patiens)

Results are not available in the source record.

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

Contact Qian Xiang, Ph.D (+86 010 66110802, xiangqz@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of major adverse cardiac events (MACE) (time frame: At 1 year). The study lists 2 primary outcomes in all. 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 NCT03161002, which also lists 2 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.
