Evaluation of Centralised TB Assay Solutions

Status Completed

Clinical Trial Summary

Tuberculosis (TB) remains a life-threatening disease partly due to increasing incidence of multidrug and extensively drug-resistant TB. Diagnostic based on culture and conventional drug susceptibility testing using media take several weeks leading to prolonged periods of ineffective therapy and ongoing transmission. Development of rapid molecular diagnostic tests for the identification of Mycobacterium tuberculosis (MTB) and drug resistance has become a high priority. The Xpert® MTB/RIF Assay does not provide information on INH-resistance and the LPA is only recommended for use in smear-positive samples, complex to perform and requires manual interpretation. Several novel assays have been recently developed/CE-marked offering high sample throughput and higher sensitivity for detection of MTB, RIF- and INH-resistance in centralized laboratories. However, published data on their performance and operational characteristics is extremely limited. This is a prospective, multicentre, diagnostic accuracy trial in which the performance of centralised TB assay solutions will be assessed at the intended setting of use with culture, phenotypic DST and sequencing as reference standard. Potential trial participants will be identified at participating TB clinics or hospitals (enrolment sites). Sputum samples will be collected and transported to the associated TB reference laboratories (testing sites). In order for the results of this trial to be generalizable, adults with symptoms compatible with pulmonary TB undergoing evaluation will be screened for inclusion at geographically diverse participating centres in high burden TB countries. Additionally, to supplement the drug-resistant cases to timely achieve accurate performance estimates, well-characterized frozen sputum samples from the FIND specimen bank will be used.
