Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The NeuMoDx EBV Quant Assay 2.0 study is a multi-center, observational clinical investigation designed to evaluate the performance of the NeuMoDx EBV Quant Assay 2.0 in quantifying Epstein-Barr virus (EBV) DNA levels in plasma samples from immunocompromised transplant patients. The study compares the NeuMoDx EBV assay's performance against an FDA-cleared comparator assay under routine clinical use conditions, utilizing both the NeuMoDx™ 96 and NeuMoDx™ 288 Molecular Systems. The aim is to demonstrate the quantitative concordance and clinical utility of the assay in monitoring EBV DNA levels as part of patient management.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is an observational, multi-center, open-labeled, prospective, and retrospective clinical evaluation aimed at assessing the performance of the NeuMoDx EBV Quant Assay 2.0 on the NeuMoDx™ 96 and NeuMoDx™ 288 Molecular Systems. Plasma samples are collected from immunocompromised patients undergoing solid organ transplant (SOT) or hematopoietic stem cell transplant (HSCT) who are at risk of EBV infection or reactivation. The study includes both fresh and frozen plasma specimens obtained as part of routine clinical care.

The primary objective is to demonstrate the quantitative concordance of the NeuMoDx EBV assay when compared to the cobas® EBV assay (Roche Diagnostics Corporation) using a predefined set of performance criteria. The study also assesses the equivalence of performance between the two NeuMoDx systems (NeuMoDx™ 96 and NeuMoDx™ 288) in quantifying EBV DNA levels across a range of clinical specimens. Secondary objectives include evaluating the assay's performance across different viral load concentrations and subgroups.

NeuMoDx EBV Quant 2.0 Assay

The NeuMoDx™ EBV Quant Assay 2.0 is an automated in vitro nucleic acid amplification test for the quantification of Epstein-Barr virus (EBV) DNA in EDTA plasma from immunocompromised transplant patients. Transplant patients are screened for EBV viral load as part of their standard of care. The remaining samples from these in vitro diagnostic nucleic acid amplification tests (NAAT) will be analyzed using the NeuMoDx EBV Quant Assay 2.0 to quantify EBV DNA in EDTA plasma. That result will be compared to a comparator in vitro diagnostic assay to evaluate the performance of the NeuMoDx EBV Quant 2.0 assay.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Immunocompromised transplant patients (Solid Organ Transplant (SOT) or Hematopoietic Stem Cell Transplant (HSCT)).
* Fresh and frozen plasma specimens derived from whole blood collected with EDTA as an anticoagulant.
* Residual fresh or frozen EDTA plasma specimens obtained from routine testing, including specimens collected from the same subject at different timepoints.
* Sufficient sample volume 1.6- 2.0 ml for testing with 2 assays plus discordant testing.
* EDTA plasma samples have been stored under the following conditions:
* 2-8° C up to 7 days and/or -20° C +/- 2° C or colder for up to 6 months following the separation of plasma from whole blood. Or fresh EDTA plasma samples that have not been stored loaded onto the NeuMoDx™ system immediately after they have been separated from whole blood.
* Frozen samples have not gone through more than two freeze/thaw cycles.

Exclusion Criteria

* Specimens not collected according to the manufacturer's instructions or study protocol.
* Lack of clear subject identification or label on a residual plasma sample
* Unable to obtain required medical chart information.
* Obvious physical damage to the residual sample.
* Specimens that have remained onboard the NeuMoDx System for longer than 8 hours prior to processing.
