NDWG launches consultation on draft TPP for a test of progression of LTBI
1 Jun 2016

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.

NDWG Annual Meeting 2015
3 Dec 2015

CTICC - International convention centre, Cape Town, South Africa

The Annual Meeting of the New Diagnostics Working Group was held on 3 December 2015 at the 46th Union World Conference in Cape Town. The meeting reviewed three main areas of activity in which the NDWG has engaged to advance TB diagnostics research and development. In the first session we examined the promises of next generation sequencing for detection of anti-microbial resistance and presented progress on the development of the ReSeqTB data sharing platform. Presentations in the second session discussed the new priorities for drug susceptibility testing in order to ensure the successful adoption of new TB drug regimens and highlighted the role of laboratory-based approaches. The third session focused on the development of tests for progression of latent TB to active disease, which are required to efficiently introduce targeted preventive therapy and support the goal of TB elimination. In particular, we reported on the outcomes of an expert meeting organized by the NDWG in collaboration with partners and shared the latest updates on the development of target product profiles and study protocols.

10 million lives saved and 45 million TB cases avoided with Stop TB Partnership 5-year investment plan
20 Nov 2015

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. Read more...

International partnership to create global TB data sharing platform
26 Jan 2015

The NDWG is partnering with CPTR, FIND and a consortium of other international stakeholders to develop a Rapid DST Data Sharing Platform. The initiative addresses the need for a centralized data resource for globally diverse genomic and other clinically relevant tuberculosis data. Data contributed from a variety of research, academic and government bodies will be reviewed for quality in a transparent manner, standardized, and eventually made accessible to TB researchers and clinicians. This collaborative effort will contribute to advance the understanding of genetic mutations and mechanisms associated with drug resistance, thus supporting the development of new diagnostic tests to detect drug-resistant TB. News release

Facilitating coordination of TB diagnostic research: NDWG workshop on sequencing data sharing

On 3-4 February 2014, the New Diagnostics Working Group held a workshop on "Enabling standards and sharing of data on the molecular basis of drug resistance" in London, UK. The event was jointly organized with the Critical Path to TB Drug Regimens (CPTR).The meeting aimed at establishing standards for the exchange of next generation sequencing data and for the combination with phenotypic DST results and clinical outcome. Participants also discussed possible mechanisms for sharing and making accessible this data to test developers, researchers, clinicians, and institutions performing diagnostics for treatment. This meeting is a successful example of how the NDWG provides a neutral coordination platform for multiple stakeholders in TB diagnostic R&D, thus playing a central convening role.

NDWG Co-Chairs, Dr Daniela Cirillo, San Raffaele Research Institute, and Dr Mark Perkins, FIND, chaired the meeting, which attracted 55 invited participants. These included experts from different backgrounds, such as TB sequencing groups, TB reference laboratories, TB clinicians, software developers, test developers, diagnostics industry, patent attorney, funding bodies, WHO, US CDC, ECDC, the European Commission, PHE and NGOs. The two-day workshop comprised of information sharing through presentations from attendees and circulation of published documents. The format of the event enabled focused debate in breakout groups and several plenary discussions aimed at consensus building.
