January 29, 2020 updated by: Green Cross Corporation

Dose Selection(Step 1), Non-inferiority(Step 2), Phase II/III Clinical Trials to Evaluated the Efficacy and Safety of Hepatitis B Virus-associated Liver Transplant Patients by Intravenously Injecting GC1102

This is a clinical study for GC1102 to demonstrate preventing the recurrence of hepatitis B virus (HBV) infection following liver transplantation and a dose-finding study to determine its optional dose.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

GC1102 is a new recombinant hepatitis B immunoglobulin (HBIG) from Chinese Hamster Ovary (CHO) cells. It is a monoclonal antibody and has high affinity and avidity to hepatitis B surface antigen and several advantages compared to HBIG derived from blood plasma of human donors. Volunteers will participate in the study, receive 24-week treatment with 80,000/100,000 IU of GC1102 or I.V HBIG and be followed up till 28 weeks.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.
