This is a phase 3, open-label, randomized clinical trial in adults and adolescents aged 15 years or older who need treatment for rifampicin-resistant tuberculosis in South Africa.
The goal of this clinical trial is to learn whether a 6-month MDR-END Plus regimen works as well as current standard of care (SoC) treatment for rifampicin-resistant tuberculosis. The trial will also learn whether the MDR-END Plus regimen is safer and easier to tolerate than SoC regimens.
The main questions this trial aims to answer are:
* Does the MDR-END Plus regimen lead to a favorable treatment outcome 12 months after treatment is stopped, compared with SoC regimens? * Do participants receiving the MDR-END Plus regimen have fewer important safety or tolerability problems during treatment and up to 90 days after treatment is stopped, compared with SoC regimens?
Researchers will compare the MDR-END Plus regimen with South African standard of care (SoC) treatment for rifampicin-resistant tuberculosis.
Participants will:
* Be randomly assigned to receive either the MDR-END Plus regimen or SoC treatment. * Take tuberculosis medicines for about 6 months, although treatment may be extended in some cases. * Attend study visits during treatment and after treatment is stopped. * Have clinical assessments, blood tests, heart tracing tests, vision and nerve assessments, and tuberculosis tests. * Be followed for 12 months after treatment is stopped.
Willing and able to voluntarily provide written informed consent to participate in the study prior to initiation of any study-related procedures. For participants under the age of 18 years, signed consent may be obtained from the child's biological parent, legal guardian, or primary caregiver in the presence of the child. Minor participants must also be willing to provide written assent for study participation.
To the best of their knowledge and abilities at screening, participants must be willing and able to adhere to the complete follow-up schedule and all study procedures.
Male or female participants aged 15 years or older.
Documented molecular drug susceptibility testing, such as TB nucleic acid amplification test, line probe assay, targeted next-generation sequencing, or culture-based phenotypic drug susceptibility testing on a sample obtained from the participant within 8 weeks prior to screening, even if rifampicin resistance is not re-confirmed on a sample obtained at screening; or
Documented Mycobacterium tuberculosis resistance in the current or prior treatment episode;
Prior exposure of 1 month or longer, unless protocol-defined exceptions are met;
Absolute contraindications to the relevant study drugs;
Use of prohibited concomitant medications within 14 days prior to enrolment.
