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

Eligibility

Inclusion Criteria:

• • Age 18 years or above;
• Symptoms suggesting pulmonary TB, i.e. persistent cough (generally =3 weeks or as

per local definition of TB suspect), and at least one of the following:

• Previously received >1 month of treatment for a prior TB episode or
• Failing TB treatment with positive sputum smear or culture after =3 months of a standard TB treatment or
• Had close contact with a known drug-resistant TB case or
• Newly diagnosed with MDR-TB within the last 30 days or
• Previously diagnosed with MDR-TB and failed TB treatment with positive sputum smear or culture after =3 months of a standard MDR-TB treatment regimen Patients meeting the above criteria will be screened by Xpert MTB/RIF or Xpert MTB/RIF

Ultra. TB patients meeting the following criteria will be included in the study:

• A clear Mtb-positive and RIF-resistant or RIF-sensitive result by Xpert MTB/RIF or Xpert MTB/RIF Ultra
• Provision of informed consent;
• Production of an adequate quantity (>3mL) of sputum

Exclusion Criteria:

• Participants will be excluded from the study if informed consent is not provided.

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.
