Master Protocol for Evaluating Multiple Infection Diagnostics for Ciprofloxacin-Resistant Neisseria Gonorrhoeae
Duke University
Summary
The goal of this study is to learn if a few investigational tests can correctly find the gene mutation (mutant allele gyrA 91F) that predicts ciprofloxacin resistance in clinical specimens that harbor Neisseria gonorrhoeae. The main question the study aims to answer: Can the investigational reflex test find the correct gene mutation (Neisseria gonorrhoeae gyrA 91F or gyrA 91S) as compared to the sequenced result? Specimens that are collected for routine clinical care and harbor Neisseria gonorrhoeae will be evaluated in this study.
Description
This is a prospective, multi-center, cross-sectional study using consecutive clinical specimens that are collected for routine clinical care and test positive for N. gonorrhoeae using an FDA-cleared molecular assay. The study evaluates the diagnostic accuracy of multiple investigational reflex tests to detect the mutant allele gyrA 91F that predicts ciprofloxacin resistance in N. gonorrhoeae, as compared to a reference standard of Sanger sequencing of the gyrA codon 91. Specimens will be tested via a reference standard of Sanger sequencing and one investigational reflex test. The target sample…
