TB PRACTECAL is a cutting-edge phase II/III clinical research project to find short, tolerable and effective treatments for people with drug-resistant tuberculosis (DR-TB).

Seizing upon the opportunity of the first new TB drugs in half a century, MSF has partnered with the London School of Hygiene and Tropical Medicine and other global leaders in medical research, as well as ministries of health in affected countries, to take action.

Together, they share one big goal: to save the lives of hundreds of thousands of people with DR-TB and close the deadly treatment gap that is fuelling the global crisis. In order to achieve this, they aim to:

  • Identify short, effective and tolerable treatments for people with DR-TB through a clinical trial compliant with international standards for good clinical practice.
  • Advocate for global access for DR-TB patients everywhere, through the adoption of a newly identified treatment regimen, if successful, into national protocols and global policy and guidelines.

Interim results published in the New England Journal of Medicine (2022) show that the new all-oral six-month treatment regimen comprising bedaquiline, pretomanid, linezolid and moxifloxacin (BPaLM) is safer and more effective at treating DR-TB than the currently accepted standard of care.

On 15th December 2022, The WHO released updated guidance for the treatment of DR-TB, now recommending programmatic use of the six-month regimens; BPaLM (Bedaquiline/ Pretomanid/Linezolid/ Moxifloxacin) and BPaL (Bedaquiline/Pretomanid/Linezolid) in people with multi-drug/rifampicin-resistant TB (MDR/RR-TB) in place of longer, existing regimens.

Update: 16 November 2023

The final results of TB-PRACTECAL have now been published in Lancet Respiratory Medicine. This new set of evidence confirms the interim 2022 results, and shows with additional precision, that BPaLM is safer and more effective than standard of care. Across the globe, this short, all-oral regimen is now one of the preferred treatments for adolescents and adults with pulmonary rifampicin-resistant tuberculosis.

The TB-PRACTECAL trial will close at the end of 2023, MSF intends to make the data publicly available in early 2024.

MSF continues its work on the next vital step;  to help transfer this new evidence into practice by supporting national TB programmes to integrate these new treatments into routine care.

In light of the recently updated WHO consolidated guidelines on DR-TB treatment, we aim to provide information on how we used these regimens in the TB-PRACTECAL trial and what it might mean for implementation.

The toolkit contains materials that can be adapted for a number of settings and languages. If you can’t see something suitable here or you would like to know more, please contact us below and we will endeavour to support you. 

We hope you find this helpful and will value your feedback no matter what your role is.

  • Tashkent, Uzbekistan, January 2019
  • Minsk, Belarus, December 2017
  • Doris Goodwin, KwaZulu-Natal, South Africa, November 2018
  • Sub-site: THINK Clinical Trial Unit, Hillcrest (formally Don McKenzie), KwaZulu-Natal, South Africa, October 2018
  • Helen Joseph Hospital, Johannesburg, South Africa, December 2019

Phase II-III clinical research

Phase II-III clinical research

TB PRACTECAL is a multi-centre, multi-arm, open-label, randomised, controlled, phase II-III trial to identify a shortened, safe, effective and tolerable new treatment regimen for adults with pulmonary multidrug-resistant tuberculosis (MDR-TB).

Breaking new ground

Designed to maximise the possibility of finding patient-centred treatments and to speed progress, we intend to:

  • Combine two new and highly promising anti-TB drug classes, diarylquinolines and nitroimidazoles, increasing the potential to radically improve treatment
  • Identify a six-month regimen to dramatically reduce treatment time
  • Utilise a pragmatic and adaptive trial design to speed progress and ensure that a new regimen is relevant for the people who need it most

Stage one of the study identified regimens containing the new drugs bedaquiline and pretomanid for further evaluation based on safety and efficacy outcomes after eight weeks of treatment.

Stage two of the study, which began in November 2020, evaluates the safety and efficacy of the best performing new regimen at 18 months, compared with the World Health Organization recommended standard of care used locally, which makes up the control arm of the trial.

Patient needs and safety lie at the heart of TB PRACTECAL, in full accordance with the Declaration of Helsinki and international standards for good clinical practice.

The new regimens in the study are designed to respond first and foremost to the needs of people with DR-TB – with few pills (no injections), taken orally, for six-months.

It is hoped that patients will experience fewer side effects so that they can comfortably complete their treatment at home.

Furthermore, the regimens should be safe and effective for people living with HIV and co-infected with DR-TB, who are particularly vulnerable.

If successful, a new treatment of this kind could enable low and middle-income countries most affected by the DR-TB epidemic to dramatically increase treatment services. And with treatment still the best form of prevention, this could help to turn the global DR-TB crisis around.

The study incorporates an important community engagement component, with an overarching strategy and country-level plans adapted to each context for optimal relevance.

At its core is the ‘commitment to creating a beneficial, respectful, sustained and transparent partnership that addresses the interests of all stakeholders in the research project, while supporting its ethical and scientifically rigorous conduct’.

To this end, TB PRACTECAL aims to:

  • Engage in a dialogue with community stakeholders, sharing knowledge and insights – in order to establish open communications, address local interests, develop mutual understanding and optimise the beneficence and relevance of the research.
  • Develop a foundation of understanding and sensitise community stakeholders about research – in order to build on the capacity, knowledge and skills of people to actively engage in an effective partnership role, in support of the study’s ethical and scientifically rigorous conduct.
  • Ensure community stakeholders are adequately informed and empowered throughout the research – in order to foster a transparent, respectful and constructive collaboration towards the successful implementation of the study.

As with all clinical trials, there are potential risks associated with using new therapies administered in new combinations.

The trial is overseen by a Data and Safety Monitoring Board, part of a strong governance structure, to ensure that the highest patient safety, scientific and ethical standards are met throughout.



Day-to-day coordination of the TB PRACTECAL study is managed by the Project Management Team, housed in the Manson Unit at MSF UK, a part of the MSF Operation Centre Amsterdam Public Health Department.  Ethical and scientific rigour is maintained via a strong governance structure, including a Steering Committee and an external Scientific Advisory Committee consisting of world-renowned experts.

An external and independent Data and Safety Monitoring Board also ensure that the highest standards in patient safety and data reliability are met.

Ethics oversight

Independent Ethics Review Boards (ERBs) are charged with protecting the rights, safety and wellbeing of clinical trial participants.

They review all aspects of a study before deciding whether it can go ahead or not. Before a site is allowed to start enrolling patients, the ERB will review all study-related materials including the protocol, and patient materials. ERB’s also perform periodic reviews throughout the study’s duration.

TB PRACTECAL has been approved by the following independent Ethics Review Boards:

  • Médecins Sans Frontières/Doctors Without Borders (MSF) Ethics Review Board
  • London School of Hygiene and Tropical Medicine (LSHTM) Observational / Interventions Research Ethics Committee
  • Uzbekistan: Ethical Committee under the Ministry of Health of the Republic of Uzbekistan
  • Belarus: Ethics Committee of the State Institution Republican Scientific and Practical Centre of Pulmonology and Tuberculosis
  • South Africa: Pharma Ethics Independent Research Ethics Committee
  • South Africa: University of the Witwatersrand, Johannesburg, Human Research Ethics Committee: (Medical)

Key structures

A Steering Committee (academic and industry) and an external Scientific Advisory Committee guide the Project Management Team. A Data and Safety Monitoring Board provides safety oversight.
