NCT03072576

Brief Summary

Consenting adults presenting with signs and symptoms compatible with pulmonary tuberculosis will be interviewed for demographic and medical information, and then will be asked to provide 3-4 expectorated sputum specimens. In the study laboratory, sputa will be tested using conventional and investigational diagnostic tests for tuberculosis and rifampin resistance.

Outcome Measures

Primary Outcomes (1)

  • Difference in sensitivity and specificity (ability to correctly identify those with TB and those without TB) between Xpert Ultra and Xpert MTB/ for Mycobacterium tuberculosis (MTB) detection (non-inferiority endpoint)

    Day 1

Secondary Outcomes (4)

  • Sensitivity of Xpert Ultra for MTB detection (ability to correctly identify those with TB i.e. true positives), stratified by smear status

    Day 1

  • Sensitivity and specificity (ability to correctly identify those with TB resistant to Rifampin and those with TB susceptible to Rifampin) of Xpert Ultra for detection of Rifampin (RIF) resistance

    Day 1

  • Difference in sensitivity and specificity (ability to correctly identify those with TB resistant to Rifampin and those with TB susceptible to Rifampin) of Xpert Ultra and Xpert MTB/RIF for detection of RIF resistance

    Day 1

  • Proportion of test attempts that do not yield a determinate result for Xpert Ultra and for Xpert MTB/RIF

    Day 1

Interventions

Next generation Xpert MTB/RIF assay, this cartridge is intended for the detection of M. tuberculosis in sputum as well as the detection of M. tuberculosis mutations associated with resistance to rifampin

Also known as: Cepheid Ultra

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Individuals who have symptoms consistent with pulmonary TB presenting to participating centres. Two groups of participants will be recruited, namely a 'Case Detection Group' and a 'Drug-Resistant TB Group'.

You may qualify if:

  • Age 18 years or above;
  • Provision of informed consent;
  • Willingness to provide 4 sputum specimens at enrolment;
  • Willingness to have a study follow-up visit approximately 42 to 70 days after enrolment
  • Clinical suspicion of pulmonary TB (including cough ≥2 weeks and at least 1 other symptom typical of TB)

You may not qualify if:

  • Receipt of any dose of TB treatment within 6 months prior to enrolment
  • Participants for whom, at the time of enrolment, the follow-up visit is judged to be poorly feasible (e.g. individuals planning to relocate)
  • Drug-Resistant TB Group
  • Age 18 years or above;
  • Provision of informed consent;
  • Willingness to provide 4 sputum specimens at enrolment;
  • Non-converting pulmonary TB cases (category I and category II failures) or multi-drug resistant (MDR) suspect\* (based on World Health Organization definition), i.e. at least one of the following: i) retreatment cases, ii) active TB cases that are MDR-contacts and iii) patients at high risk for MDR-TB as determined by local program (e.g. prisoners)
  • none
