Clinical Trial Summary

FIND and partners intend to address the need for a multi- and extensively drug-resistant tuberculosis (M/XDR-TB) diagnostic solution for patients in settings with a high burden of drug-resistant tuberculosis (DR-TB) though the development, evaluation and introduction of an Xpert MTB/XDR assay

Intervention

Device:
Cepheid Gene Xpert MTB/XDR
The Xpert MTB/RIF assay (Cepheid, Sunnyvale, CA) is an integrated, automated, cartridge-based system for MDR-TB diagnosis that uses the GeneXpert instrument platform. WHO confirmed evidence to support the widespread use of the Xpert MTB/RIF assay in 2010 and the assay has since been widely used in TB programs, but it is only capable of identifying Mycobacterium tuberculosis (Mtb) and detecting RIF resistance. The Xpert MTB/XDR assay will be evaluated for INH and second-line resistance detection, and to recommend its use in diverse clinical settings. The focus of this protocol is the multicentre clinical evaluation.
