Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Carvedilol has been shown to be more potent in decreasing portal hypertension than propranolol. But the efficacy of carvedilol to prevent esophageal varices progression in nucleoside analogue (NUCs) treatment HBV related cirrhotic patients was unclear. Previous RCT study aimed to explore the effects of carvedilol for the prevention of the esophageal varices progression on HBV cirrhotic patients with anti-viral therapy has been conducted (NCT03736265). Patients who have completed 2-years treatment in RCT Study of carvedilol will receive another 2-years extension therapy, aiming to investigate the long-term efficacy of carvedilol for the prevention of esophageal varices in treated HBV cirrhotic patients. Patients were allocated according to the outcome of EDGs at 2-year during RCT study. Patients will be assessed at baseline and every six months for blood cell count, liver function test, HBVDNA, AFP, prothrombin time, liver ultrasonography, and Fibroscan. A third EGDs will be performed at 4-year.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Subjects who completed the 2-year RCT study of carvedilol in HBV cirrhotic patients with anti-viral therapy;
  • Subjects who are willing to participate the extension study.

Exclusion Criteria:

  • Subjects who refused to receive 2-year EGD examination during the previous RCT study;
  • Subjects who could not compliance with the protocol judged by investigators;

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The progression incidence of esophageal varices after 4-year therapy
Time Frame: 4-year

Progression of esophageal varices defines as follows:

  1. Varices developed from small (F1) to medium or large (F2/F3)
  2. Varices developed from medium (F2) to large (F3)
  3. New-onset red sign without change in the degree of varices.
  4. Bleeding from esophageal varices.
4-year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The incidence of liver cirrhosis decompensation
Time Frame: 4-year
Cumulative rate of liver cirrhosis decompensation, including bleeding, ascites, hepatic encephalopathy, ect.
4-year
The incidence of hepatic cellular carcinoma, death or liver transplantation.
Time Frame: 4-year
Cumulative rate of hepatic cellular carcinoma, death or liver transplantation.
4-year
The change of non-invasive assessment score reflecting liver fibrosis.
Time Frame: 4-year
Higher scores mean a worse outcome.
4-year
The change of non-invasive assessment score reflecting liver function.
Time Frame: 4-year
Higher scores mean a worse outcome.
4-year
