About this study
Official title: A Phase 3, Open-Label, Randomised Controlled Trial to Evaluate a 6-Month "MDR-END Plus" Regimen (Bedaquiline, Delamanid, Delpazolid, Levofloxacin and Pyrazinamide) Versus the South African Standard of Care Treatment for Rifampicin-Resistant Tuberculosis
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.
Read more
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.
Read the detailed description
This is a phase 3, multi-site, open-label, randomized controlled trial conducted in South Africa. The study will enroll adults and adolescents aged 15 years or older who require treatment for pulmonary rifampicin-resistant tuberculosis.
Participants will be randomized in a 1:1 ratio to either the investigational arm or the control arm. Randomization will be stratified by study site and HIV status. The study is open-label because participants and investigators will know which treatment is assigned.
Participants in the investigational arm will receive the MDR-END Plus regimen, consisting of bedaquiline, delamanid, delpazolid, levofloxacin, and pyrazinamide. Regimen adaptations may be made according to the drug susceptibility profile of the participant's Mycobacterium tuberculosis strain and drug suitability. Treatment may be extended according to protocol-defined criteria.
Participants in the control arm will receive South African standard of care (SoC) treatment for rifampicin-resistant tuberculosis according to national guidance and site practice.
Participants will attend study visits during treatment and after treatment discontinuation. Study assessments will include clinical evaluations, safety laboratory tests, electrocardiograms, microbiological assessments, and protocol-specified safety and tolerability assessments. Participants will be followed for 12 months after treatment discontinuation.
The primary efficacy analysis will assess whether the MDR-END Plus regimen is non-inferior to SoC regimens for favorable treatment outcome at 12 months after treatment discontinuation. The co-primary safety and tolerability analysis will assess whether the MDR-END Plus regimen is superior to SoC regimens during treatment and up to 90 days after treatment discontinuation, contingent upon demonstration of efficacy non-inferiority.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MDR-END Plus regimenDrug
Also called Bedaquiline, delamanid, delpazolid, levofloxacin, and pyrazinamide
The investigational MDR-END Plus regimen consists of oral anti-tuberculosis drugs including bedaquiline, delamanid, delpazolid, levofloxacin, and pyrazinamide. Dosing and duration will follow the study protocol, with modifications based on body weight, drug susceptibility, drug suitability, and protocol-defined treatment extension criteria.
Standard-of-care (SoC) treatmentDrug
Also called South African standard of care treatment
Participants in the control arm will receive South African standard-of-care treatment for rifampicin-resistant tuberculosis according to national treatment guidance and site practice. The regimen may vary according to drug susceptibility results, drug suitability, and clinical judgement.
| Study group | Role | What they receive |
|---|---|---|
| Investigational arm | Experimental | Participants assigned to the investigational arm will receive the 6-month MDR-END Plus regimen, consisting of bedaquiline, delamanid, delpazolid, levofloxacin, and pyrazinamide, with protocol-defined modifications based on drug susceptibility and drug suitability. Treatment may be extended up to 9 months according to protocol-defined criteria. Receives: Drug: MDR-END Plus regimen |
| Control arm | Active comparator | Participants assigned to the control arm will receive standard of care (SoC) treatment for rifampicin-resistant tuberculosis according to South African national guidance and site practice. Receives: Drug: Standard-of-care (SoC) treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Favourable outcome at 12 months after treatment discontinuation
Proportion of evaluable participants with a favourable outcome at 12 months after treatment discontinuation in the investigational arm compared with the control arm. The primary efficacy analysis will assess whether the MDR-END Plus regimen is non-inferior to SoC regimens.
Measured: 12 months after treatment discontinuation
Composite safety and tolerability endpoint
Proportion of evaluable participants meeting the predefined composite safety and tolerability endpoint during treatment and up to 90 days after treatment discontinuation in the investigational arm compared with the control arm. The co-primary safety and tolerability analysis will assess whether the MDR-END Plus regimen is superior to SoC regimens, contingent upon demonstration of efficacy non-inferiority. The composite endpoint includes protocol-defined adverse events, serious adverse events, adverse events of special interest, and adverse events leading to permanent discontinuation of any study drug.
Measured: During treatment and up to 90 days after treatment discontinuation
Secondary outcomes (2)
Model-derived delpazolid AUC0-24
Model-derived delpazolid area under the plasma concentration-time curve from 0 to 24 hours (AUC0-24) will be estimated from the final population pharmacokinetic model in participants receiving the MDR-END Plus regimen. This exposure metric will be used to support dose evaluation across predefined weight groups, including assessment of the effect of HIV status.
Measured: Sparse PK sampling at Weeks 2, 8, and 26 after randomisation; intensive PK sampling at Week 2, pre-dose and 1, 2, 4, 8, and 24 hours post-dose.
Model-derived delpazolid Cmax
Model-derived delpazolid maximum plasma concentration (Cmax) will be estimated from the final population pharmacokinetic model in participants receiving the MDR-END Plus regimen. This exposure metric will be used to support dose evaluation across predefined weight groups, including assessment of the effect of HIV status.
Measured: Sparse PK sampling at Weeks 2, 8, and 26 after randomisation; intensive PK sampling at Week 2, pre-dose and 1, 2, 4, 8, and 24 hours post-dose.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing MDR-END Plus regimen and Standard-of-care (SoC) treatment in people with Rifampicin-Resistant Tuberculosis, run by Seoul National University Hospital at 2 sites in South Africa.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 30 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in South Africa. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jae-Joon Yim, MD, PhD (+82-2-2072-4029, yimjj@snu.ac.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Favourable outcome at 12 months after treatment discontinuation (time frame: 12 months after treatment discontinuation). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2026.
