Advancements in the TB diagnostics pipeline: FIND and NDWG annual symposium
22 October 2020
Tuberculosis (TB) diagnostics are needed to detect exposure, diagnose disease and drug resistance, and to monitor improvement under treatment in both primary healthcare and laboratory settings. The Foundation for Innovative New Diagnostics (FIND) and the Stop TB Partnership’s New Diagnostics Working Group (NDWG) bring to you the latest developments in TB diagnostics R&D. You will hear from leading global experts on the advancements in the TB diagnostics pipeline, improvements in the detection of drug-resistant TB, next-generation sequencing and the diagnosis of TB infection.
NDWG and WHO launch "Framework for the evaluation of new tests for tuberculosis infection"
The document provides details on study design, populations, reference standards, sample size calculation and data analysis to guide the future development of these tests.
Approximately a quarter of the world’s population is estimated to be infected with Mycobacterium tuberculosis. Treatment of TB infection, also known as tuberculosis preventive treatment (TPT), aims to prevent the development of TB disease, and is one of the critical components to achieve the ambitious targets of the WHO End TB Strategy. At the United Nations High-level Meeting (UNHLM) on TB in 2018, countries committed to provide TPT to at least 30 million people in 2018-2022.
NDWG launches survey for latent TB infection (TBI) test manufacturers.
Diagnosis and treatment of tuberculosis (TB) infection (TBI) is critical to achieving the global End TB targets. The Stop TB Partnership’s New Diagnostics Working Group (NDWG) housed at the Foundation for Innovative New Diagnostics (FIND) is conducting a survey in partnership with University College London (UCL), to review the landscape of tests for TBI and identify gaps that need to be filled to facilitate the development and introduction of new tests for TBI.
Survey link: https://ucl.onlinesurveys.ac.uk/ltbi-test-landscape
For the purpose of this survey, a test for TB infection is defined as one that measures immune response to stimulation by Mycobacterium tuberculosis antigens and is intended to be used for identifying individuals to be given treatment of TBI.
The survey will close at 5:00pm GMT on 13 July 2020.
Inviting all test manufacturers to participate. Please help us in sharing this information widely.
NDWG launches consultation on draft TPP for next-generation DST
The New Diagnostics Working Group and its Task Force on Next-Generation Sequencing and DST are conducting an online consultation on the draft Target Product Profile (TPP) for Next-Generation Drug-Susceptibility Testing at Peripheral Centres.
The online survey will enable to gather input from a large group of stakeholders representing researchers, high-burden countries, governmental and non-governmental organizations, test developers and the patient community. Participants will have the opportunity to evaluate the key performance and operational characteristics, in order to inform the update of the High-priority target product profiles for new tuberculosis diagnostics and build consensus around the updated version of the TPP.
Since the first release of this document in 2014, WHO issued updated treatment guidelines for multidrug- and rifampicin-resistant TB to reflect landmark changes in MDR treatment regimens. To ensure that relevant guidance be provided to drug developers, the drug prioritization and related assumptions for the other characteristics in the TPP were revised accordingly.
Draft Results from the survey

Joint FIND and NDWG symposium
30 October 2019, Hyderabad, India
Lighting the path to TB care - advances in diagnostics
Each year, on the sidelines of the world’s largest conference on lung health, the Foundation for Innovative New Diagnostics (FIND) and the Stop TB Partnership’s New Diagnostics Working Group (NDWG) organize a joint symposium to highlight the latest developments in tuberculosis (TB) diagnostics R&D.
Diagnostics often do not exist, are inaccessible, or cost too much. They remain under-resourced and overlooked and together our aim is to shine a light on the urgent need to develop and deliver TB diagnostics that are affordable and accessible. #ItsTime to ensure that rapid TB diagnostic testing is available to all those who need it. The symposium is open to all and will begin with a welcome coffee along with snacks. We look forward to seeing you in Hyderabad, India.
#ItsTimetoDiagnoseTB - flyer launched at #UnionConf
Quality diagnostics and treatment must be available to patients wherever they seek care. Current TB diagnostics (e.g. microscopy) are not fit-for-purpose and miss a huge number of patients with TB and drug resistance. Indeed, diagnosis is the biggest gap in the TB cascade of care. This needs to urgently change and the NDWG is excited to have launched a flyer on the sidelines of the 50th Union World Conference on Lung Health emphasizing why TB #DiagnosisMatters.
The NDWG releases factsheet on next-generation WGS to support its introduction in TB endemic countries
On the occasion of World TB Day, the NDWG releases a new factsheet “Next-generation Whole Genome Sequencing for TB control. A rapid and accurate diagnostic tool for better treatment and prevention”. By providing key information in an accessible way for a non-scientific audience, the document aims to improve broad understanding of the benefits of adopting Next-generation Whole Genome Sequencing (NG-WGS) in TB diagnosis, thus ultimately fostering its introduction into clinical practice in low- and middle-income countries with a high burden of drug-resistant TB.
WGS based on novel sequencing technologies has great potential for rapidly identifying the bacteria complete drug resistance profile and for enabling clinicians to select the best anti-TB treatment regimen, thus improving patient outcomes and reducing the spread of the disease. Moreover, NG-WGS makes it possible to understand transmission patterns with more accuracy, thereby improving the effectiveness of public health interventions aimed at controlling and preventing the spread of TB.
Accelerating the adoption of Next-generation Whole Genome Sequencing (NG-WGS) for the rapid diagnosis of drug-resistant TB will lead to the delivery of personalized treatment and will increase survival rates. Moreover, it will improve the effectiveness of public health prevention and control strategies, thereby bringing the TB epidemic closer to an end.

The presentations and audio are now available on the NDWG website as follows:
NDWG launches consultation on draft TPP for a test of progression of LTBI
The New Diagnostics Working Group and its Task Force on tests for progression of LTBI to active disease have recently launched an online consultation to gather input on a draft Target Product Profile (TPP) for a test of progression of latent tuberculosis infection (LTBI).
Reactivation of LTBI is the source of the vast majority of new TB cases in low transmission areas. As global TB incidence declines, preventing progression from LTBI to active TB will be crucial for cutting transmission and reaching the goal of TB elimination. The introduction of targeted and cost-effective treatment of individuals with LTBI requires a diagnostic test to identify the small proportion of latently infected persons who will progress to active disease.
A prognostic test for determining the risk of progression from LTBI to active disease is currently unavailable. To support the development of this new test, FIND has defined a draft TPP with contribution from the NDWG LTBI Task Force and other experts in the field. This document will provide guidance to diagnostic developers as to the key characteristics that the test needs to fulfill in order to meet requirements.
The NDWG is conducting an online survey to gather input from a group of stakeholders representing researchers, endemic countries, governmental and non-governmental organizations, test developers and the patient community. Participants will have the opportunity to evaluate the key performance and operational characteristics as defined in the TPP in order to build large consensus. Results will be discussed by an expert group which will be convened by the NDWG Task Force on LTBI on July 1st 2016 in Milan, Italy, in order to finalize the TPP and submit the document to WHO for endorsement.

10 million lives saved and 45 million TB cases avoided with Stop TB Partnership 5-year investment plan
The Stop TB Partnership launches the new Global Plan to End TB 2016-2020 - The Paradigm Shift
The world is losing its battle with tuberculosis (TB), which is now the biggest infectious killer globally, causing 1.5 million deaths every year. Without a clear investment plan and a complete overhaul in how this disease is tackled, TB is unlikely to be eliminated until the end of the 22nd century, and the world will miss the recently announced Sustainable Development Goal to end TB by 2030.
This will require a US$ 56 billion investment package from 2016-20, which will see 29 million people with TB receive treatment; save more than 10 million lives and prevent 45 million people from getting ill with TB. This investment will offer a huge return for affected individuals, their families, and their communities, and one of the highest returns on investment of any health intervention - an estimated US$ 85 for each dollar invested. This is clearly outlined in the new Global Plan to End TB 2016 -2020 launched by Stop TB Partnership.
The battle with TB cannot be won without new tools. For this, as part of the total package, the Global Plan calls for a US $9 billion investment needed for vital research and development to create a vaccine that protects people of all ages against TB, highly sensitively rapid diagnostic tests that can be implemented at the point of care, and drug regimens (including for drug-resistant TB) that are highly effective and non-toxic.

FDA approved Xpert MTB/RIF for simultaneous detection of tuberculosis and rifampicin resistance
The U.S. Food and Drug Administration (FDA) recently allowed marketing of the Xpert MTB/RIF assay, the first FDA-reviewed test that can simultaneously detect bacteria that cause tuberculosis (TB) and determine if the bacteria contain genetic markers that make them resistant to rifampicin, one of the most used first-line drugs for the treatment of TB.
The FDA reviewed the Xpert MTB/RIF assay through the de novo classification process, a regulatory pathway for some low- to moderate-risk medical devices that are not substantially equivalent to an already legally marketed device. In support of the de novo petition the manufacturer submitted data that included an assessment of the test’s accuracy in identifying the TB bacteria and the rifampicin-resistant strains as compared to validated test methods.
The Cochrane Library publishes new systematic review on Xpert MTB/RIF
Xpert® MTB/RIF can accurately and quickly detect both TB and drug-resistant strains, according to a new study. The authors of a new systematic review assessing the diagnostic accuracy of the Xpert test published in The Cochrane Library say their study can provide timely advice for clinicians and policymakers in countries where TB is a major public health problem.
The researchers, from the Cochrane Infectious Diseases Group, McGill University and the Foundation for Innovative New Diagnostics (FIND), analysed data from 18 studies involving nearly 8,000 people, with most studies being carried out in low- and middle-income countries.

Horse riders, text messages and creative solutions improve TB detection in Lesotho
Lesotho is a small land-locked country surrounded by South Africa. It has both the second highest incidence of TB (640 per 100,000) and the second highest HIV co-infection rate of adult TB cases in the world.
In this predominantly mountainous country with three-quarters of the population living in rural settings, diagnosis remains inaccessible to the majority of affected communities. The Stop TB Partnership’s TB REACH initiative in collaboration with FIND brings testing and treatment to the most remote villages through innovative approaches. Horse riders ensure sample collection in secluded areas where riding is the only transport option and village health workers use a mobile text message system to track test results and put patients on treatment without delay.
WHO warns against the use of inaccurate blood tests for active tuberculosis (TB)
20 July 2011 - WHO has called for countries to ban the use of serological (blood) tests to diagnose active TB disease in a policy issued today, which described the results from these blood tests as inaccurate and a major risk to the health of patients.
Despite the wide use of these blood tests, evidence reviewed by a WHO expert group and published today concluded that "commercial serological tests provide inconsistent and imprecise estimates" and that "it is strongly recommended that these tests not be used for the diagnosis of pulmonary and extra-pulmonary TB."
More than a million TB blood tests (also known as serodiagnostic or serological tests) are carried out every year, usually at a substantial cost to patients.
Today's recommendation does not apply to serological tests for latent TB infection, currently under review by WHO and findings expected to be released next month.

2011 report on TB R&D investment trends by TAG
Funding was flat in 2010 and only covered less than one-third of the global need
26 October 2011
New data released by the Treatment Action Group (TAG) and the Stop TB Partnership finds that in 2010 the world spent just $617 million in TB research and development. This amount represents 0.3% less than 2009 funding levels. It is also less than one-third of the $2 billion annual target the Stop TB Partnership estimates is needed to provide new interventions to eliminate TB.
Although in 2010 funding to support TB diagnostics research grew by 15% to reach $44.6 million, this increase follows a 22% decline between 2008 and 2009 and the funding level in 2010 is still below 2008’s $50 million investment. Moreover, this amount only represents 13% of the $340 million annual target set by the Global Plan. A massive and essential resource mobilization effort is needed to enable the development of a low-cost and effective POC diagnostic test for use at the community level.

The Stop TB Partnership launches the 2011 World TB Day campaign
25 January 2011
The World TB Day campaign 2011 has been launched yesterday by the Stop TB Partnership and is now live with a dedicated website. This is the second year of the two-year campaign On the move against tuberculosis whose goal is to galvanize innovation in TB care and research. It is inspired by the new objectives of the Global Plan to Stop TB 2011-2015: Transforming the Fight-Towards Elimination of Tuberculosis, which was launched by the Stop TB Partnership in October 2010. This new plan identifies all the research gaps that need to be filled to bring rapid TB tests, faster treatment regimens and a fully effective vaccine to market and, therefore to the people who need them. The campaign focuses on recognizing individuals - doctors, nurses, managers, patients, activists and advocates, and researchers around the world who have found new ways to fight and stop TB in different settings and can serve as an inspiration to others. This year's campaign also features Dr. Catharina Boehme, who is Co-Chair of the Point-of-care Tests Subgroup of the New Diagnostics Working Group.
Pathways to better diagnostics for tuberculosis
At it's Annual Meeting 2009 in Cancun, Mexico, the New Diagnostics Working Group released a new publication entitled:
Pathways to better diagnostics for tuberculosis: A blueprint for the development of TB diagnostics.
This publication, with contributions from over 30 experts, aims to provide a comprehensive, well-referenced blueprint to guide researchers, clinicians, industry partners, academics, and TB controllers in all sectors in all aspects of TB diagnostics development, from concept to evaluation, implementation, scale-up, delivery and impact. It is designed to help identify the most promising TB tests, to push them towards alignment with the needs and requirements of the areas where tuberculosis is most prevalent, and to help determine why some are held up in development. The blueprint also is intended to help boost coordination and collaboration across the diagnostic research and development landscape, while leading to greater success in advancing new tests by clarifying that landscape and the various development steps. Finally, considering the paucity of national regulations regarding the quality of diagnostics and the need for a strong evidence base to support health policy decisions, this blueprint seeks to inform and advance independent evaluation and assessment of the new tools’ likely impacts based on scientifically sound methodology, in addition to well-defined standards of practice for study design.

McGill University is Canada's leading research university, ranked as one of the top 25 universities in the world. McGill has a large, active, diverse research group on tuberculosis, encompassing several disciplines, including epidemiology, clinical research, public health, genomics, diagnostics, molecular epi, health economics, modeling, sociology and international health. Members of the research group have a strong track record for innovative biomedical, clinical, epidemiologic and social research.
McGill invites recent PhD or MD graduates to apply for a one year, full-time fellowship, starting Jan 2010. The postdoctoral fellow will function as a junior investigator, participating fully in research and related scholarly activities. The fellow would participate in ongoing TB diagnostic research projects, help coordinate specific TB research projects, coordinate IRB/ethics submissions, conduct data management & analysis, prepare manuscripts, assist in writing grant proposals, and conduct systematic reviews & meta-analyses and methodological/statistical projects on diagnostic research.
New Evidence-based Tuberculosis Diagnosis website
22 August 2009
The Stop TB Partnership's New Diagnostics Working Group (NDWG) is pleased to present a new website resource called Evidence-based Tuberculosis Diagnosis, available at: http://www.tbevidence.org
Several agencies, groups and individuals have contributed to the development of this comprehensive resource. These include the Foundation for Innovative New Diagnostics (FIND), the Special Programme for Research and Training in Tropical Diseases (TDR), the Global Laboratory Initiative (GLI), and the Public Health Agency of Canada (PHAC).
This aim of the website is to provide the most comprehensive single source of evidence syntheses, policies, guidelines and research agendas on TB diagnosis. It provides access to all published systematic reviews on TB diagnostics (grouped by various test types or platforms), all the relevant policies, guidelines and research agendas on TB diagnosis, and several reports, monographs and training modules and slide presentations on TB diagnostics.
The website also provides detailed guidance on how to conduct and report diagnostic research on TB, guidance on how to perform systematic reviews of diagnostics, tools on guideline development, including GRADE, and documents on improvement of laboratory quality and practice. Up to date information on the current TB diagnostics pipeline is also provided, along with SOPs and package inserts for several tests, and specimen banks and databases. All information is provided as open access, with no registration or fee requirements.
This new website resource addresses a long-standing need for a single portal that compiles all critical evidence on TB diagnosis, along with relevant policies and guidelines for clinicians, health professionals and policy makers. We welcome your feedback and suggestions for improvement!
Diagnostic Tools Initiative by IUATLD - TREAT TB
10 August 2009
The International Union Against Tuberculosis and Lung Diseases, under the USAID-supported TREAT TB Initiative, has organized a Diagnostic Tools Initiative to comprehensively identify potential tools and strategies (existing and new approaches), determine the sufficiency of evidence for their use and application, identify gaps in the evidence that could be addressed by research, commission research in priority areas, and partner with selected groups to test approaches to determine how to apply new knowledge to the challenges faced by NTPs.
As a part of this work, the Union undertook a broad environmental scan of the work being undertaken in the area of new diagnostic tools for TB, and have generated a search database to catalog this information searchable by diagnostic technology, country and research organization.
This tool can be found at the TREAT TB web portal: http://www.treattb.org/NewDXtools.aspx
The Union invites you to visit the site, examine the utility and content of this tool, and provide critical feedback to them which will help to refine the tool, its content and utility.

- a continued decline in the number of people falling ill from TB, but still an enormous global burden of 8.7 million new cases in 2011;
- an estimated 1.4 million deaths from TB, including half a million women, underlining the disease as one of the world’s top killers of women;
- reduced rates of new disease and deaths in all of WHO’s six regions, although the African and European Regions are not yet on track to achieve goals to halve 1990 levels of mortality by 2015;
- a persistently slow progress in the MDR-TB response, with only 1 in 5 patients estimated to exist being diagnosed worldwide.
- IGRAs and the TST cannot accurately predict the risk of infected individuals developing active TB;
- Neither IGRAs nor the TST should be used for the diagnosis of active TB disease;
- IGRAs are more costly and technically complex to do than the TST. Given comparable performance but increased cost, replacing the TST by IGRAs in resource-constrained settings is not recommended.
