About this study

Official title: Early Precise Diagnosis and Intervention of Cirrhotic Portal Hypertension (CPT) Based on a Noninvasive 3D-virtual-model of Hepatic Portal System (3D-vHPS)

The aim of this study is to investigate the possibilities of early and precise management to decrease portal vein pressure in cirrhotic patients, guided by a non-invasive 3D-virtual-model of hepatic portal system (3D-vHPS). Healthy volunteers are enrolled to determine the normal range of pressure density in different sites of HPS. Cirrhotic patients without visible gastro-esophageal varies by endoscopy are randomly enrolled to virtual portal vein pressure gradient (vPVPG) monitored or non-vPVPG monitored groups. Non-vPVPG groups are followed-up and treated according to Baveno V consensus in portal hypertension. Patients in vPVPG-monitored groups are followed-up by anatomic computed tomographic angiography (CTA) and Doppler ultrasound every six months. Once vPVPG is above 12mm of mercury (Hg), participants will receive carvedilol treatment. All cirrhotic patients are followed-up with the incidence of portal hypertension-related complications, mortality rate and life quality assessment.

Read the detailed description

The non-invasive 3D-HPS is a newly-developed test to determine vPVPG based on anatomic computed tomographic angiography (CTA) and Doppler ultrasound. In this study, vPVPG is determined by the 3D-HPS.

Being tested
Carvedilol, 3D-vHPS, Routine endoscopic procedures
Medical subject headings
Hypertension, Portal, Fibrosis

What participants receive

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

  • CarvedilolDrug

    Also called Coreg

    Carvedilol starts from 6.25mg daily and increase to 12.5mg once daily in next week if being tolerated.

  • 3D-vHPSDevice

    This 3D model of HPS is rebuilt by a software combining the anatomic information of vessels from CTA (computed tomographic angiography) and the blood stream speed of targeted vessel from Doppler Ultrasound.

  • Routine endoscopic proceduresProcedure or surgery

    These include esophageal band ligation and tissue glue injection in the fundus of stomach by upper GI endoscopy if there are visible varies in cirrhotic patients. There routine procedures are done to prevent potential varies associated bleeding.

Study groups in NCT02925975
Study groupRoleWhat they receive
Healthy controlsOtherHealthy volunteers are enrolled as controls to get a normal range of pressure gradient in different sites of hepatic portal system (HPS), such as portal vein, superior mesenteric vein, inferior mesenteric vein and splenic vein. All enrolled healthy subjects should undergo anatomic computed tomographic angiography (CTA) and Doppler ultrasound for only one time, to rebuild a 3D-vHPS by computer.
Receives: Device: 3D-vHPS
Treatment group guided by vPVPGExperimentalEnrolled cirrhotic patients with virtual portal vein pressure gradient (vPVPG) above 12mmHg are only treated by oral carvedilol. Once there are visible varies under the endoscopy, participants will be treated with routine endoscopic procedures.
Receives: Drug: Carvedilol; Device: 3D-vHPS; Procedure: Routine endoscopic procedures
Follow-up group guided by vPVPGExperimentalCirrhotic patients with vPVPG lower than 12mmHg are followed-up with anatomic CTA and Doppler ultrasound every six months. Once vPVPG is higher 12mmHg or visible varies under the endoscopy, participants will be rescheduled to treatment group guided by vPVPG.
Receives: Drug: Carvedilol; Device: 3D-vHPS
Follow-up group guided by endoscopyActive comparatorCirrhotic patients are followed-up by routine endoscopy. Once there are visible varies, participants will be treated according to Baveno V consensus in portal hypertension, such as oral carvedilol and routine endoscopic procedures.
Receives: Drug: Carvedilol; Device: 3D-vHPS; Procedure: Routine endoscopic procedures

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Carvedilol, 3D-vHPS and Routine endoscopic procedures in people with Portal Hypertension and Cirrhosis, run by Changqing Yang 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 10 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 25 Feb 2020. 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 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?

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?

Incidence of portal hypertensive complications: ascites and variceal bleeding (time frame: 3 years). 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?
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 25 Feb 2020; AzTrials last refreshed its copy on 6 Nov 2026.
