Study Description

Brief Summary:

The NGAL TestTM is a particle-enhanced turbidimetric immunoassay for the quantitative determination of neutrophil gelatinase-associated lipocalin (NGAL) in human EDTA plasma for testing on automated clinical chemistry analyzer.

The First Indication for Use: An NGAL test result above the assay cutoff as an aid in the risk assessment for the development of stage II or III acute kidney injury (AKI) within 1 day of patient assessment in patients in the intensive care unit (ICU) who are hypotensive (MAP<70 mmHg) and/or receiving vasopressor support. Second Indication for Use: In patents with stage II or III AKI, NGAL measurement aids in the risk assessment of the development of persistent (≥2 days) stage 2 or 3 AKI.

The Primary Objective for this clinical trial is to validate that the NGAL test using a cutoff of 140 ng/ml shows clinical performance in predicting the development of moderate or severe acute kidney injury within 1 day. The Secondary Objective is to validate that the NGAL test shows clinical performance in predicting persistent moderate or severe acute kidney injury during any contiguous 2 day interval.

It is anticipated that up to 20 Clinical Sites in US will participate in the trial. The study sites will recruit consecutive patients meeting the inclusion and exclusion criteria who are admitted to hospital in an ICU or critical care setting. Patients will receive their clinical standard of care including standard laboratory and other testing as requested by each subject's physician.

The Secondary Objective is to validate that the NGAL test shows clinical performance in predicting persistent moderate or severe acute kidney injury during any contiguous 2 day interval.

It is anticipated that up to 20 Clinical Sites in the US will participate in the trial. The study sites will recruit consecutive patients meeting the inclusion and exclusion criteria who are admitted to hospital in an ICU or critical care setting. Patients will receive their clinical standard of care including standard laboratory and other testing as requested by each subject's physician. Enrollment is estimated to take approximately six months and the trial will be stopped when the Adjudication Panel has diagnosed at least 85 patients with AKI stage 2 or 3.

Each subject who is enrolled in the study will only have 4 blood draws as part of NGAL TestTM Trial with no additional study activities with the exception of data collection. The NGAL results will not be returned to the treating physician for use in the health management of the study subjects.

Groups and Cohorts

Group/Cohort	Intervention/treatment
Kidney Injury	Device: NGAL Test; The purpose of this study is to demonstrate that BioPorto Diagnostic's NGAL test is able to assist in determining the risk for acute kidney injury for patients who have been admitted to the intensive care unit.

Outcome Measures

Primary Outcome Measures :

1. Sensitivity and Specificity [ Time Frame: Up to 7 days in ICU or until discharge ]
   To demonstrate that the sum of sensitivity and specificity is greater than 1 using a cutoff of 140 ng/mL when compared to the primary clinical endpoint AKI as adjudicated KDIGO Stage 2/3 AKI

Eligibility Criteria

• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No
• Sampling Method: Probability Sample

Study Population

Intensive care patients diagnosed at high risk for developing AKI.

Criteria

Inclusion Criteria:

• • Subjects should be enrolled within 24 hrs. of ICU admission, from ED or floor within 24 hrs. of ICU admission or if the subject is from another ICU no more than 24 hrs. from presentation.

    o Cardiovascular SOFA score of >= 1(MAP<70 mmHg and/or receiving any vasopressor support

  • Subject or representative written informed consent
