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

Hepatitis b virus (HBV) related acute-on-chronic liver failure (ACLF) is a serious condition with high mortality rate in China. But there still lacks of effective therapies in treatment of HBV related ACLF, except liver transplantation. RL-1 Novel Human-derived Bio-artificial Liver treatment may be an effective and safe therapy due to the previous clinical data. This study is to investigate the clinical efficacy and safety of RL-1 Novel Human-derived Bio-artificial Liver treatment in patients with HBV related ACLF.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Plasma exchange group
10 patients will receive conventional treatment plus plasma exchange
Other: Plasma exchange

Experimental: RL-1 Novel Human-derived Bio-artificial Liver treatment group
10 patients will receive conventional treatment plus RL-1 Novel Human-derived Bio-artificial Liver treatment
Other: RL-1 Novel Human-derived Bio-artificial Liver Treatment
Patients will receive RL-1 Novel Human-derived Bio-artificial Liver treatment for three times in two weeks. The volume of plasma exchanged in the system is about 4000 millilitre per time.

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
Adverse events
Time Frame: 4 week
All adverse events (i.e. fever, allergy, bleeding, hypotension, thrombosis) are observed in the follow-up.
4 week

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
Survival rate

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
