Study on the Efficacy and Safety of Avatricopal in Patients With CLD Complicated With Thrombocytopenia

October 14, 2024 updated by: Yao Xie, Beijing Ditan Hospital

Study on the Efficacy and Safety of Avatricopal in Patients With Chronic Liver Disease With Selective Invasive and Minimally Invasive Surgery Combined With Thrombocytopenia

In this study, patients with chronic liver disease undergoing selective invasive and minimally invasive surgery combined with thrombocytopenia were enrolled. After enrollment, liver disease treatment was supplemented with avatripopal for 5 days. Biochemical indexes of avatripopal were monitored during treatment and after withdrawal. The proportion of patients with platelet count ≥50×10^9/L on the day of selective invasive and minimally invasive surgery was analyzed. The incidence of adverse events was observed.

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

This is a single-center, single-arm, prospective study. Patients with chronic liver disease undergoing selective invasive and minimally invasive surgery combined with thrombocytopenia. After enrollment, liver disease treatment was supplemented with avatripopal for 5 days. The baseline demographic data and biochemical data of the subjects were collected. Biochemical indexes of avatripopal were monitored during treatment and after withdrawal. The proportion of patients with platelet count ≥50×10^9/L on the day of selective invasive and minimally invasive surgery was analyzed. The incidence of adverse events was observed. To investigate the efficacy and safety of avatripopal in chronic liver disease patients with thrombocytopenia undergoing elective invasive and minimally invasive surgery. To provide reference for related clinical treatment.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Patients with chronic liver disease complicated with thrombocytopenia undergoing elective invasive and minimally invasive surgery were admitted to the experimental group for clinical observation.

  • Age ≥18 years old, male or female;
  • Baseline platelet count < 50×10^9/L;

  • A history of major cardiovascular disease within the 6 months prior to enrollment (e.g., aggravated congestive heart failure, arrhythmias known to increase the risk of thromboembolic events [such as atrial fibrillation], coronary or peripheral arterial stenting or angioplasty, and coronary or peripheral arterial bypass grafting);
  • the subject is allergic to avatripopal or any of its excipients;
  • Exclude vulnerable people with mental disorders and other disabilities
  • The investigator believes that accompanying medical history may affect the safe completion of the study.

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
Proportion of patients with platelet count ≥50×10^9/L on the day of elective invasive and minimally invasive surgery.
Time Frame: 2024-2025
Proportion of patients with platelet count ≥50×10^9/L on the day of elective invasive and minimally invasive surgery.
2024-2025

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.
