New Medicines and Novel Approaches for MDR-TB

Posted: 18 Mar, 2014   Recommendations: 15   Replies: 92

Drug resistant tuberculosis is a major public health concern. With the introduction of Xpert MTB/RIF and other technologies, early diagnosis is becoming possible. Through the intensive work of countries and partners, access to treatment has been scaled up in most settings.

Still, with the exception of a few settings, treatment success of multidrug resistant TB cases is suboptimal. Patients are often on long treatment regimens with various adverse events. Recently two new medicines, bedaquiline and delamanid were approved for use under specific conditions. A new short treatment regimen has been piloted in some settings and is showing promising results.

Joining us to discuss these new developments from March 24 – 28 are:

     • Dr Aung Maug, Bangeladesh
     • Dr Mamel D. Quelapio, The Philippines
     • Dr Dalene von Delft, South Africa
     • Dr Arnaud Trébucq, France
     • Dr Masoud Dara, Belgium

Please feel free to start sharing questions and thoughts now. We look forward to this discussion.

Thank you.

I will be very happy to join this discussion. The duration of treatment and particularly the injectable phase and the management of MDR TB in children are a big challenge. Monitoring patients for a long period and daily DOT is waring to patients, health care workers and the health system as a whole. It also requires a lot if resources which are not easy to come by especially in resource limited setting.

Dear Colleagues,

Thank you for giving us the opportunity to participate in discussion with such critical themes. For the beginning its will be interesting to know:
1. When final version of the WHOs’ Policy update about Xpert MTB/RIF system for the diagnosis of PTB and EPTB in adults and children will be available? (Still we have access to the pre-publication version only;
2. We were informed about WHOs conditional recommendation, that Bedaquiline (inhibitor of ATP synthase) may be added to a WHO-recommended regimen in adult patients with pulmonary MDR-TB. We know that EMA has approved Sirturo (Bedaquiline) for conditional use in EU for adults with Pulmonary MDR-TB. Of course we need more detailed information about bedaquilone (doses and duration, effective combinations with other II line drugs and etc.), but most critical to know when we will have recommendations for using of Delamanid (Nitroimidazole-OPC 67683 – inhibitor of M. tuberculosis cell wall synthesis and cell respiration)?

Natalie Lorent Replied at 9:57 PM, 19 Mar 2014

Hi all! Thanks for providing us the opportunity to learn more and share experiences on shorter/newer MDR-TB treatment regimens.
From my experience working in Cambodia, there is a dire need for shorter, less toxic and (hopefully more) effective regimens to treat MDR-TB. New diagnostics such as the Xpert TB/RIF assay have substantially increased MDR-TB diagnosis, as well as shortened time to start treatment. However, encouraging patients to start and - more importantly - adhere to a 2-year toxic and demanding treatment regimen can be challenging. Although, the team here tries to tailor it as much as possible to the patient’s needs by combining hospital-based with ambulatory treatment, the current regimen still puts an big strain on patients and an already overburdened (and low funded) tuberculosis programme. A shorter regimen would alleviate some of the burden. However, despite favourable reports from Bangladesh and the African experience with shorter treatment regimens, in many developing countries, the NTPs will only consider it once recommended/approved by WHO. I realise and fully agree it is important to gather enough evidence, especially when introducing newer drugs. I wonder whether using shorter regimens with existing drugs (such as used in Van Deun’s regimen and the slightly modified regimen used in the Union’s STREAM trial – end of 2016 ) could be supported sooner – eventually under strict conditions? I’m eager to learn about preliminary results or updates from other studies that might improve quality of life of our (MDR-)TB patients.

Dear all,
thanks to include me in the discussion.

While we expect better tolerated regimen we'll have to struggle with existing ones for a while.
This raise the issue of hearing toxicity management, linked to injectable AG in particular.

I heard about an audiometry test administered by lay personnel in Kwazulu Natal and transmitted over the internet to a distant proficient technician for interpretation. I'd like to know more about the experience as it could be one of the possible way to prevent severe impaired hearing.

Another issue of concern is the high occurrence of hypothyroidia in MDR/HIV population (India) but also in Lesotho and Botswana (landlocked countries: link to access to sea/iodized salt ?) MDR cohorts (not sure about the link with HIV there) : how to handle patients without access to TSH test ? Clinical diagnosis, cautious introduction of thyroxin supplementation, dosage adjustment based on the clinical response ?

I have the impression these issues are not highlighted enough: shouldn't funding for MDR be linked to side effect management component, for many reasons both at individual and public health levels ?

Pakistan ranks fifth in terms of TB burden, at an alarming figure of 620,000 TB patients out of a total population of 177 million people. It is the world’s fourth highest multidrug-resistant tuberculosis burden country in the world. Although TB is a treatable disease, in Pakistan, pharmacies frequently stock out of the required medications.

Today, in honor of World TB Day, JSI's blog The Pump features an article about how assistance from the USAID | DELIVER PROJECT is helping Pakistan fight tuberculosis (TB). Since 2012, the USAID | DELIVER PROJECT has worked with Pakistan's National Tuberculosis Control Program to enhance the scope of the country's web-based Logistics Management Information System and the warehouse management system for TB Drugs.

I am Arnaud Trebucq, and I am working for The Internatinal Union Against TB and Lung Disease, based in Paris.
With the NTPs of Benin, Cameroon and Niger, we have implemented a 12-month short-course regimen for MDR-TB in these countries, using the same drugs as Armand Van Deun in Bangladesh but prolonging the continuation phase for 8 months instead of 5. We have treated 238 proven MDR-TB patients with a 90% cure rate, no failure and no relapse so far.
Because of this preliminary success, since beginning of 2013, we are implementing a 9-month regimen (4KmMfxPtoHCfzEZ/5MfxCfzEZ) in 9 francophone countries in Africa: Benin, Cameroon, Niger, Cote d'Ivoire, Burundi, Central African Republic, DR Congo, Burkina Faso, Rwanda. In each country, the protocole has been approved by the National Ethics Committee. Drugs were bought by different partners, and already more than 200 patients have been enrolled. Since January 2014, we begin to buy the drugs also with the Global Fund money because we get the approval of WHO for this observational study. Still too early to have much results, but so far, patients convert very quickly and we do not have specific problems with the replacement of gatifloxacin by moxifloxacin.

Masoud Dara, MD Replied at 6:12 PM, 24 Mar 2014

Thank you very much Arnaud for joining the panel and this important introduction, very good to hear about your preliminary results.

Dear Dr. Arnaud

I would be very interested to learn more about your 12 month short-course regimen for MDR-TB with a 90% cure rate among the 238 proven MDR cases. Would it be possible to know 1) the inclusion criteria of these 238 cases (background history and DST Pattern) 2) the treatment regimen used. 3) Your protocol for discontinuation of injectables and understanding of “Cure” 4) The number of months of follow up so far post declaration of cure. This is indeed very encouraging to learn more about your experience and hope to learn more about it.

Dear Nelly and colleagues,

I am pleased to share with you the link of the WHO interim guidance on the use of Bedaquiline for the treatment of MDR-TB. The link also provides access to the interim guidance document, Frequently Asked Questions and other background material:

Full link to pdf:

The WHO also scheduled a meeting on development of an Interim Guidance for the Use of Delamanid in the treatment of Multidrug-Resistant Tuberculosis for April this year (next month).

With regards to the development of hypothyroidism in MDR TB patients:
It is a relatively common problem in MDR TB patients (especially as a side effect of Ethionamide therapy)
and therefore recommended to do routine TSH screening after 3 months of therapy.
I personally developed hair loss early during therapy and therefore tested already during my second month of therapy. I already had low TSH levels. Signs of hypothyroidism: hair loss, dry skin, fatigue, depression and impaired memory. Because the signs and symptoms are relatively non specific and common in TB patients, routine screening really is necessary.
I however recovered well after starting thyroxine supplementation at the usual dose of 50 micrograms a day. My levels were repeated every 3 months and my treating physician suggested tapering the eltroxin 1 month after stopping MDR TB treatment. My levels then stayed normal. Most patients recover normal thyroid levels after stopping therapy and should be reassured.

Please let me know if I could help in assisting any other questions, especially from a patient's perspective.

Mamel Quelapio, MD Replied at 2:38 PM, 25 Mar 2014

I am Mamel Quelapio from the Philippines. I am happy to join this week's discussion. My work in MDR-TB started with being a clinic physician in 1999 in a public-private mix DOTS (PMMD) and MDR-TB clinic of an NGO, the Tropical Disease Foundation. In collaboration with the NTP, and under guidance by the Green Light Committee, we worked in the setting up, expansion and initial scaling up of the programmatic MDR management in the country until 2010. My work also involves providing PMDT technical assistance to neighboring countries. I will be happy to share my experience in whatever way, and, at the same time, learn from those who have experience with the new TB drugs.

Jay Achar Replied at 5:50 PM, 25 Mar 2014

In response to Dr Dara, MSF started recruiting patients into an operational research study in Uzbekistan in late 2013. The study is being conducted in an established TB project (~15 years) in close collaboration with the MoH and has received institutional and national ethical approval. The context is one of high second line drug (SLD) resistance, a relatively sparsely populated region with extremes of weather, and medical teams well versed in the provision of WHO-endorsed DR and DS TB treatment.

The treatment protocol mirrors very closely the Bangladesh regimen with substitution of Moxifloxacin for Gatifloxacin, while using culture and smear results to guide treatment decisions. ECG monitoring, as well as standard protocolised side-effect management is being performed. In keeping with the aims of the project, almost all patients commence and continue treatment on an outpatient basis.

Given the high burden of DR-TB in this region, I hope this study will allow us to add a more tolerable, shorter, simpler and cheaper option for a sub-group of patients. Recruitment is ongoing, but my understanding is that other countries in the region are eagerly awaiting interim and final results.

Petros Isaakidis Replied at 2:36 AM, 26 Mar 2014

Dear colleagues,
Even though the discussion is on new medicines and novel approaches we have noticed a thread on hypothyroidism and we would like to share with you some of our experiences, with HIV/MDR-TB co-infected patients.
Hypothyroidism is a very common adverse event (54% of patients in our Mumbai cohort, similarly frequent in a Lesotho cohort) but fortunately it is easy to early diagnose and manage. Therefore, it is a shame that in many programmes we only test for hypothyroidism when it gets symptomatic. We feel our patients have been suffering enough, both from their disease and their treatment; we should do our very best to aggressively prevent any AE and any additional suffering, that also compromises adherence.
We attach here a paper in which we discuss our experiences, including some suggestions on the frequency and intervals of screening, as well as some issues with point-of-care TSH diagnostics and the difficulties in resource limited settings.
Apologies for diverting from the main topic.

Dalene von Delft Replied at 8:00 AM, 26 Mar 2014

Dear colleagues

Please find attached a graph showing my QT times as measured during the first two weeks of bedaquiline therapy.
As you may know, the first two weeks is the loading phase where patients have to take 4 tablets daily, then thereafter they have to take only two tablets 3 times a week.

My husband is a doctor and we had an old ECG machine at home, therefore we measured and calculated my QT times almost daily during the loading phase and thereafter about weekly. We however did not measure it at the exact same time every day, therefore we think the variability in the curve may be from moxifloxacin peak and trough levels. Luckily my QT times never went above the "prolonged range".

I was the first patient to use moxifloxacin and bedaquiline together. I did experience palpitations at times and once had a halter ECG for 24 hours, which showed a normal sinus tachycardia of 130 beats per minute at night (at rest). The cardiologist suggested taking magnesium supplementation as it has a stabilizing effect on the heart. I also avoided stimulants (caffeine and vigorous exercise like jogging).

We are using Bedaquiline for an XDR TB patient currently. I contacted Dr. Peloquin's lab at the University of Florida where we send our therapeutic drug monitoring for TB drugs:

He said that they do not currently offer BDQ levels as a clinical test. However they do have an assay for research purposes. According to Dr. Peloquin, therapeutic ranges for BDQ are not known; normal ranges could be constructed but have not been to date. We will store some plasma just in case an assay becomes available.

For monitoring, we did daily EKGs for the first two weeks as the patient is also on other QT prolonging drugs (high dose IV Moxi, Clofazamine) and now are doing weekly EKGs. We are also using a Zoll LifeVest wearable automated cardiac monitor/defibrillator. This allows us to keep the patient monitored with immediate access to defibrillation in the event of an arrhythmia, while still allowing him to go outside of the hospital TB Unit and visit family.

For those providing medical care for TB patients, how is your work being documented today? I am interested in understanding if more paper-based or more automated systems are in place. For those using paper or technology, what are the key challenges you face that if resolved would make your work more effective in helping those in need?
I appreciate any responses you may share.
Thank you,

Dear colleagues

Thank you for taking part in this discussion. It was wonderful to hear about people’s interests, concerns and work all over the world. I hope that we can continue having these discussions in future and that there would be better options and outcomes for Drug Resistant TB patients in the near future. Please contact anytime if you need a patient's perspective on an issue or if you have patients in need of social support, please invite them to visit our website,, or facebook page,

Best regards

Dear Trisha,
Thank you for your question regarding documentation. There are efforts to either initiate or expand electronic recording in some of the high-burden countries in the Western Pacific Region, but paper-based recording using Treatment Cards and Registers, remains to be the standard means of documenting programmatic care in TB for now. In the Philippines, the NTP uses both paper-based and electronic recording, the latter using the Integrated TB Information System (ITIS), a web-based system for both TB and MDR-TB data, that captures most of the information in the Treatment Cards. Its use is currently being expanded countrywide. Key challenges include the need for a dedicated person to do regular data entry in every site, and also for the system to be able to generate routine reports for notification and cohort analysis.

To everyone, let me take this opportunity to thank you for your interest and participation in this interesting panel discussion!

Dear colleagues,

Speaking of new TB medicines and regimens, I thought it would be relevant to announce a new version of our TB pharmaceutical management tool for forecasting, quantification, and early warning tool designed to improve procurement processes and planning for TB treatment.

The new version of the tool and User Guide can be accessed at the QuanTB website,

Feedback and questions for QuanTB version 1.0.2 are very welcome; all comments can be shared through the new QuanTB forum at or here on GHD.

I am so sorry as I never got to see these mails before !! It seems I
missed a great opportunity

Dr. Quelapio,
Thank you very much for taking the time to respond regarding documentation. As someone providing user-friendly electronic solutions to those in low-resource settings, I would also be interested in hearing what you feel are the key components to the most effective systems. We feel user input early on, systems that are designed for challenging environments and appropriate training are critical. What else would you include? What do you see as the biggest value to electronic systems (accuracy, reduction of administrative burden, better reporting, etc)?

Thank you all for this dialogue and for your work to improve the lives of so many. I am happy to be part of this community.
Trisha Finnegan, Biometrac

Dear Trisha,

In my opinion, key in an effective electronic information system would be
accuracy, timeliness (ability to reflect real-time data), linked with the
ability to produce consolidated reports routinely. For large countries and
expanded programs, a web-based feature would be most beneficial. However,
all these have to be balanced with setting-specific conditions, e.g., staff
availability and internet connectivity. I hope that helps.

Dr. Quelapio,
I understand and agree. Thank you very much for taking the time to share your perspective, you hit on some important key points.
I wish you well in your work!

Dear Salem,

Arnaud from the UNION responded your question as follows:

Dear Salem
Some more about the 12month-short-course regimen. The treatment regimen used
was: 4KmGfxPtoHCfzEZ/8GfxCfzPtoEZ, with Gatifloxacin used at the normal
dosage: 400 mg per day. In Cameroon and Niger, the prothionamide was kept
during the continuation phase but not in Niger and the results were very
similar in the 3 countries. We used 12-month regimen instead of 9-month
because the opposition to short course regimen for MDR-TB was terribly
strong and we did not dare to go straight for 9-month. However, the
conversion of the sputum and of the cultures was so rapid that it is obvious
for us that 9-month is more than enough. There was no specific inclusion
criteria apart from known allergy to one of the product. In these three
countries the short regimen is the standard for MDR cases. Our definition of
“Cure was the international one, with 5 negative cultures after conversion,
but the cultures performed after the treatment was finished were also
counted. For all patients, the follow-up was minimum one year after stopping
the treatment. We should publish papers in the following months probably in
the International Journal of Tuberculosis and Lung Disease hopefully before
the end of the year and you will be able to find more details. Arnaud"

All the best

The Union

Dear Arnaud,
These results are very impressive and we are all looking forward to seeing the results published. Would you be able to describe the model of care used in these settings? Ie. were patients hospitalised for treatment initiation or for a set period, and how was treatment supervised?

Masoud Dara, MD Replied at 5:01 AM, 16 Apr 2014

Dear members of the DR-TB Community, Dear Panelists, Arnuad, Dalene and Mamel,

I am writing to thank you for an interactive dicussion on New Medicines and Novel Approaches for MDR-TB. We had 90 questions and answers on this topic. It is very difficult to summarize the discussion since there are ongoing studies on this topic and I understood some of our members could not provide further inputs due to the confidentiality arrangements they are currently bound to. New Medicines and shorter treatment regimen are promising, but we do need further evidence and their dissemination as soon as possible. I suggest we keep this discussion line open and share views and information as the new evidence arise. For your information, there are currently 3631 members from 149 countries in our community spanning a total of 1630 organizations.

I take the opportunity to wish Happy Easter to those who celebrate it.

All the best,

Thank you so much Amoud for your very kind and helpful response which actually cleared number of questions but opened up for more queries. However, I would wait to see more details when the study is published later on. With this I cc. Dr. Caminero for further input from his side with many thanks.
