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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Registered male or female primary Liver transplant candidate
  • Age ≥18 years old
  • Signed: 1) written informed consent document and 2) authorization to use and disclose protected health information

Exclusion Criteria:

  • Acute, fulminant liver failure
  • Prior solid organ or bone marrow transplant
  • Chronic use of hemodialysis or diagnosis of chronic renal failure, defined as chronic serum creatinine of >3 mg/dl for >2 weeks and/or requiring hemodialysis
  • Multi-organ transplant
  • Ventilator dependent
  • Dependent on > 1 IV inotrope to maintain hemodynamics

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

Time Frame: 7 days
Participants with Early liver Allograft Dysfunction (EAD) or primary non-function, defined as presence of one or more of the following criteria: AST level > 2000 IU/ml within the first 7 postoperative days; Bilirubin ≥ 10 mg/dl on postoperative day 7; INR ≥ 1.6 on postoperative day 7; or Primary non-functioning graft within the first 7 days (defined as irreversible graft dysfunction requiring emergency liver re-transplantation or death, in the absence of immunologic or surgical causes)
7 days
Primary Safety Endpoint: Liver Graft-related Serious Adverse Events (LGRSAEs) up to 30-days Post-transplant Per Patient
Time Frame: 30 days

30 days

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
Patient Survival at Day 30 After Transplant
Time Frame: 30 days after transplant
Patient survival at day 30 after transplantation
30 days after transplant
Patient Survival at Initial Hospital Discharge Post Liver Transplant

Patient survival at initial hospital discharge post liver transplantation
at initial hospital discharge post liver transplant, an average of 11 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evidence of Ischemic Biliary Complications Diagnosed at 6 Months
Time Frame: 6 months post transplant
