Intraoperative Dialysis in Liver Transplantation (INCEPTION)

February 4, 2017 updated by: Sean M Bagshaw, University of Alberta

Intra-Operative Continuous Renal Replacement Therapy in Liver Transplantation: A Phase II Randomized Controlled Trial (INCEPTION)

Patient with liver failure waiting for liver transplantation are often hospitalized and commonly supported in an intensive care unit prior to surgery. These patients are sick, and in addition to the complications of a failing liver, other organs such as the kidneys often fail as well. As a consequence, these patients are at an increased risk for complications related to their kidney failure during their liver transplantation procedure. One potential method to diminish the risk of these complications is to provide dialysis support to these patients during their liver transplantation in the operating theater in the form of continuous renal replacement therapy (CRRT). While this is increasingly being performed and is theoretically appealing, there is very little information to support this practice. In addition, the use of CRRT during surgery is not entirely without risk. The investigators have performed two preliminary studies on the use of CRRT during liver transplantation and our data would strongly support the need to conduct further higher-quality studies to better evaluate its feasibility, safety and usefulness. Our proposed study is for a randomized trial comparing the use of CRRT during surgery with standard supportive care in sick patients with liver failure scheduled to receive a liver transplantation.

Study Overview

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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: Standard intraoperative support (no CRRT)

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
Number of patients adhering to the prescribed protocol
Time Frame: Intra-operative (From the induction of anesthesia to trasnfer from the OR to the ICU, average 6-8 hours)
Will be defined as the proportion of patients adhering to the prescribed protocol.
Intra-operative (From the induction of anesthesia to trasnfer from the OR to the ICU, average 6-8 hours)
Number of patients with adverse events
Time Frame: Intra-operative (From the induction of anesthesia to trasnfer from the OR to the ICU, average 6-8 hours)
This will be defined by the proportion of patients experiencing intra-operative adverse events, serious adverse events and complications related to the study intervention.

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.
