About this study

Official title: Determine the Safety/Efficacy of Ticagrelor in Post-transplant Patients With Hepatic Artery Thrombosis (HAT)

Hepatic artery thrombosis (HAT) represents a major cause of graft loss and mortality after Pediatric liver transplantation. Ticagrelor (a new reversible inhibitor of P2Y12 receptor with faster onset of action and greater platelet inhibition) was used to treat patients with pediatric post-transplant hepatic artery thrombosis (HAT) compared to low molecular weight heparin.

Read the detailed description

In pediatric patients with post-transplant hepatic artery thrombosis (HAT) , low molecular weight heparin is a commonly used method. Ticagrelor, a direct-acting and reversible ADP receptor antagonist, is now the most commonly used ADP receptor antagonist in the treatment of coronary diseases. Compared to its predecessor clopidogrel, the pharmacokinetic profil of ticagrelor is more predictable, demonstrating a faster onset of action and a more consistent platelet inhibition. However, because of the excellent antithrombotic effect and increased bleeding potential, it is recommended that major bleeding, such as OPCAB or CABG surgery, be expected with a high probability, and in case of fatal surgery, the drug should be discontinued for 5 days. The present study is to evaluate the safety and efficacy of Ticagrelor in pediatirc receipt with post-operative HAT.

Being tested
Ticagrelor Oral Tablet [Brilinta], Low molecular weight heparin

What is being measured

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

  1. Contrast-Enhanced Ultrasonography-Based Hepatic Perfusion Index

    The peak systolic maximum velocity (Vmax) of the HA, and HA resistive index (HARI)

    Measured: 3 months

Secondary outcomes (2)
  1. High on-treatment platelet reactivity (HPR)

    HPR defined as platelet reactivity index (PRI) ≥50% using VASP analysis

    Measured: Two hours after the injection of either active drug or placebo

  2. Post-operative major bleeding event

    post-operative major bleeding defined as HAT related bleeding

    Measured: within 72 hours after operation

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ticagrelor Oral Tablet [Brilinta] and Low molecular weight heparin in people with Hepatic Artery Thrombosis and Liver Transplant; Complications, run by RenJi Hospital 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 3 inclusion and 11 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 1 Jul 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?

Results are not available in the source record.

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

Contact Hao Feng, MD. Ph.D (+8615000901110, surgeonfeng@live.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Contrast-Enhanced Ultrasonography-Based Hepatic Perfusion Index (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Jul 2021.
