About this study

Official title: A Prospective, Multicenter, Single-arm Clinical Study of PTFE Covered Stent for Treating Portal Hypertension.

To validate the safety and efficacy of TIPS (Transjugular Intrahepatic Portosystemic Shunt) using PTFE covered stent in the treatment of portal hypertension.

Read the detailed description

This trial is a prospective multi-center single-arm confirmatory study. A total 177 subjects will be enrolled in multiple centers nationwide. Subjects who meet the trial requirements, fulfill the inclusion criteria, voluntarily participate in the study, and provide informed consent will undergo TIPS using the PTFE covered stent for the treatment of portal hypertension. Follow-up assessments will be conducted at discharge, as well as at 30 days, 90 days, 180 days and 360 days postoperatively. Secondary endpoint measures include surgical success rate, all-cause mortality, device/procedure-related mortality, incidence of adverce events, and serious adverse event rates. The trial aims to comprehensively assess the safety and efficacy of the PTFE covered stent produced by Enlight Medical Technologies (Shanghai) Co., Ltd..

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transjugular Intrahepatic Portosystemic shuntDevice

    The experimental device is a class III implanted shunt device, which will be used to create a shunt between intrahepatic and portosystemic to reduce portal hypertension.

What is being measured

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

  1. Primary shunt patency rate

    shunt dysfunction was defined as a TIPS stenosis >=50% or complete occlusion. Primary patency referred to continuous unassisted patency of the shunt.

    Measured: 1 year

Secondary outcomes (3)
  1. Technical success rate

    Successful implantation of a PTFE covered stent to create an intrahepatic portosystemic shunt and successful retrieval of the delivery system.

    Measured: immediately after procedure

  2. Procedure success rate

    PPG (portosystemic pressure gradient) reduces more than 20% or PPG <=12mmHg

    Measured: immediately after procedure

  3. Treatment success rate

    Treatment success is defined as the success of the procedure without major adverse event.

    Measured: during the perioperative period

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

Contact Echo Hu (08615221991087, echo_hu@enlight-medical.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary shunt patency rate (time frame: 1 year). 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?
