Diagnostic Accuracy of a Host-response Based Diagnostic Tool for Distinguishing Between Bacterial and Viral Etiologies in Pediatric Patients (AutoPilot)

October 4, 2021 updated by: MeMed Diagnostics Ltd.

A Multi-center, Prospective, Pilot Study to Validate the Diagnostic Accuracy and Assess the Potential Clinical Utility of a Host-response Based Diagnostic Tool for Distinguishing Between Bacterial and Viral Etiologies in Pediatric Patients Presenting to the Emergency Department With Respiratory Tract Infection (RTI) or Fever Without Source (FWS)

This is a prospective clinical validation study of a novel regulatory approved (CE-IVD) diagnostic assay called ImmunoXpert™ that will enroll 1222 pediatric patients. The study aims to externally validate the tool's diagnostic accuracy and estimate the potential improvement in health and economic outcomes following the usage of ImmunoXpert™. Additionally, statistical analysis will be performed to compare ImmunoXpert™ accuracy to current practice lab testing (e.g. WBC, CRP, and PCT) and clinical suspicion at time of requisition. Enrolled patients will be managed according to the current standard of care and per standard institutional procedures.

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

3 months and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Eligible subjects from both genders that present to the ED due to suspected RTI, or FWS. Each of these patients falls into one of the following categories:

  1. Patients with an acute bacterial infection
  2. Patients with an acute viral infection
  3. Patients with an acute co-infection (bacterial and viral)
  4. Patients with an undetermined disease etiology

Description

Inclusion Criteria:

  • Legal guardian signs an informed consent
  • Documented peak temperature ≥ 38°C (100.4°F)

  • Clinical suspicion of RTI (OR) fever without a clear source after clinical examination

Exclusion Criteria:

  • Another episode of febrile infection within the past 2 weeks
  • Antibiotic treatment of over 48 hours
  • Congenital immune deficiency (CID)
  • A proven or suspected HIV, HBV, HCV infection

Design Details

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
To validate the diagnostic accuracy and assess the clinical utility of a host-response based diagnostic tool, for differentiating between bacterial and viral etiologies in pediatric patients >90 days old with suspicion of RTI or FWS
Time Frame: 0-7 days after the initiation of symptoms
0-7 days after the initiation of symptoms

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
Time Frame
To compare the diagnostic accuracy of a host-response based diagnostic to currently available lab measures (WBC, ANC, CRP and PCT), using sensitivity and specificity measures and predetermined cutoffs
Time Frame: 0-7 days after the initiation of symptoms
0-7 days after the initiation of symptoms
To compare ImmunoXpert™ results with the physician suspected diagnosis at time of patient recruitment and compared to the reference standard diagnosis
Time Frame: 0-7 days after the initiation of symptoms
0-7 days after the initiation of symptoms

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.

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.
