Access Anti-HCV Assay European Union (EU) Clinical Trial Protocol (HCV-EU-10-18)

12. Juli 2021 aktualisiert von: Beckman Coulter, Inc.

Evaluation of the Beckman Coulter Access Anti-HCV Assay as an Aid in the Diagnosis of HCV Infection: EU Clinical Trial Protocol

The objective of this study was the collection and testing of clinical samples to determine the clinical performance in terms of diagnostic accuracy measured by specificity and sensitivity of the Access anti-Hepatitis C Virus (anti-HCV) assay on the DxI 9000 Access Immunoassay Analyzer. The Design Input Document (DID) indicates performance requirements and minimum target enrollment numbers (based on those in the CTS) of blood donor, hospitalized patient and known HCV antibody (Ab) positive samples for novel anti-HCV assays. A secondary objective was to determine the false initial reactive rate (IRR) of the Access anti-HCV assay.

Detaillierte Beschreibung

The study involved a multicenter, prospective and retrospective collection of samples, and testing of samples with the investigational Access anti-HCV assay. Subject sample enrollment was targeted to be approximately 8,000 specimens including approximately 6,000 blood donors and 1,500 hospitalized individuals for the specificity populations and 500 confirmed HCV Ab positive patients for the sensitivity population, required by European Union's Common Technical Specification for clinical validation of in vitro diagnostic medical devices and marketing needs to align with competitor submissions. Retrospective collection included HCV Ab positive genotyped samples from existing vendor collections meeting all inclusion/exclusion criteria.

All samples collected were anonymized, leftover, remnant samples and therefore member state or Institutional Review Board/Independent Ethics Committee approval was not required. Diagnostic sensitivity and specificity were evaluated for sample antibody status determined by a CE-marked anti-HCV assay (Abbott ARCHITECT anti-HCV assay for hospitalized patient and positive samples or Abbott PRISM HCV assay for blood donor samples) and Immunoblot testing with FUJIREBIO INNO-LIA HCV Score, if necessary. HCV RNA Polymerase Chain Reaction (PCR) or genotyping was requested or was available on all Immunoblot positive samples for further characterization, but these results were not used to determine final antibody status.

A portion of hospitalized patient samples (target 700/1500) and the majority of positive HCV Ab samples were collected and stored frozen prior to testing. A targeted portion of 800 hospitalized patient samples, 30 known positive samples and all blood donor samples were collected and tested fresh. Fresh blood donor and fresh hospitalized patient samples were used to determine false Initial Reactive Rate (IRR).

Intervention / Behandlung
Known HCV Ab Positive Patients
leftover samples be tested with both reference anti-HCV assay and Access anti-HCV assay according to respective instructions for use (IFU) or study guide, as applicable, to determine non-reactive (NR), initial reactivity, and repeat reactivity. Reference assay will be Abbott Architect anti-HCV assay for positive samples.

All samples were tested with both reference anti-HCV assay and Access anti-HCV assay according to respective instructions for use (IFU) or study guide, as applicable, to determine non-reactive (NR), initial reactivity, and repeat reactivity. Reference assay was Abbott Architect anti-HCV assay. For blood donors, Abbott PRISM HCV was used as reference.

For the specificity cohorts (blood donor and hospitalized patient samples), all HCV Ab positive results will have supplemental confirmation testing with HCV Immunoblot for final HCV Ab status
