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

1 second to 1 week (Child)

Accepts Healthy Volunteers

No

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
Time Frame
Free Bilirubin (UB) Serum Levels
Time Frame: first day of infusion at 3 g/kg/day
first day of infusion at 3 g/kg/day
Free Bilirubin (UB) Serum Levels
Time Frame: second day of infusion at 3 g/kg/day
second day of infusion at 3 g/kg/day

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
Unbound Free Fatty Acid (FFAu) Serum Level
Time Frame: first day of infusion at 3 g/kg/day
To measure unbound free fatty acid level, a fluorescent probe called Acrylodan-Labeled Intestinal Fatty Acid Binding Protein 2 (ADIFAB2) was used. The ADIFAB2 fluorescent probe is a fatty acid binding protein complexed with a fluorescent group. Once mixed with a sample, the ADIFAB2 fluorescent probe binds all unbound free fatty acid in the sample; therefore, measurement of fluorescence indicates the amount of unbound free fatty acid in the sample. After binding of the ADIFAB2 fluorescent probe to the sample, fluorescence intensities are measured at two wavelengths (550 nanometers and 457 nanometers), and for this outcome measure the R value is reported. The R value is the ratio of the fluorescence intensity at 550 nanometers to the fluorescence intensity at 457 nanometers.
