Normal Human Plasma Level of iNOS Study

November 23, 2013 updated by: Dr. Robert Webber, Research & Diagnostic Antibodies

Determination of the Normal Human Plasma Level of Inducible Nitric Oxide Synthase (iNOS) Using the PliNOSa Test

The discovery that inducible nitric oxide synthase (iNOS) circulates in people who are developing the sepsis pathology has provided an opportunity to develop a first-in-class diagnostic test for the onset of sepsis. This study is designed to determine the normal human plasma level of circulating iNOS as the initial reference level against which hospitalized patients at risk for the development of sepsis can be compared to ascertain if the patient is at risk for becoming septic based upon an elevated level of plasma iNOS.

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.

Detailed Description

Infections in intensive care units (ICUs) and other hospital settings can be caused by different types of organisms, such as bacteria and fungi. Yearly, these infections cause at least 2 million patients in the USA to enter the early stages of the sepsis pathology (pre-sepsis) which will lead to more than 750,000 cases of sepsis that can deteriorate into life-threatening severe sepsis with organ dysfunction and septic shock with multiple organ failure and result in more than 250,000 deaths per year. At present, an accurate clinical lab test to predict the onset of the sepsis pathology does not exist. Thus, there is a large unmet clinical lab need for a test that can aid physicians in assessing the risk their hospitalized patients have for developing the sepsis pathology. A reliable test for predicting very early the onset of sepsis would be a major medical breakthrough. However, a reference level for normal healthy individuals is needed against which plasma levels can be compared for increased (or decreased) levels of iNOS.

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 to 79 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Reference values will be obtained from 100 plasma samples obtained from healthy normal humans collected prospectively under an IRB approved protocol and informed consent after blood donation for use in research. The 100 normal human plasma samples will be assayed using the PliNOSa test.

Description

Inclusion Criteria:

  • Male or female
  • Aged 18-79 years of age
  • In generally good health

Exclusion Criteria:

  • Cannot be a prisoner

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Normal healthy adults
The concentration of iNOS will be measured in plasma samples obtained at the time of blood donation from normal healthy adult humans

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
Determination of the normal healthy human reference range for plasma iNOS
Time Frame: At time of blood donation
The primary endpoint is the determination of the normal human plasma level of iNOS as the reference interval of the mean and it's 95% confidence interval. .

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2012

Primary Completion (ACTUAL)

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. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
