TB-CAPT MTB/XDR Study
South Africa753 participantsStarted 2021-05-14
Plain-language summary
The Cepheid Xpert MTB/XDR cartridge, which runs on the same platform as Xpert MTB/RIF Ultra, has been developed to detect additional resistance to isoniazid, fluoroquinolones and second-line injectable anti-tuberculosis drugs and provides results within 2 hours and on primary samples. An evaluation of the the Xpert MTB/XDR assay is currently underway in clinical settings in South Africa, India and Moldova. The TB-CAPT MTB/XDR Study will add further diagnostic accuracy and feasibility data to the evidence base for the Xpert MTB/XDR assay.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Mtb-positive, rifampicin-resistant respiratory specimen identified on Xpert MTB/RIF Ultra
Exclusion Criteria:
* Residual SR-sputum mix not retained or not found
* Patient previously included in the study
Exclusion for diagnostic accuracy and time-to-result endpoints:
* Insufficient residual SR-sputum mix remaining for Xpert MTB/XDR (\<2 ml)
* Xpert MTB/XDR unsuccessful
* No second / follow-up specimen received
* Second / follow-up specimen culture-negative, contaminated or not available
* Reference standard uninterpretable (phenotyping or WGS)
* Where phenotypic susceptibility testing results are uninterpretable, specimens will still be included in WGS comparison
* Where WGS results are uninterpretable, specimens will still be included in phenotypic susceptibility testing comparison
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
