The TB-CAPT (Close the gap, increase Access, provide adequate Therapy) project will provide evidence for impactful implementation of tuberculosis (TB) and TB/HIV co-infection diagnostic strategies including drug-susceptibility testing through a series of trials in Tanzania, Mozambique, and South Africa.
The TB-CAPT is funded by the European and Developing Countries Clinical Trials Partnership (EDCTP) and will run for 3.5 years, with the planned completion in 2023.
It is estimated that each year more than 10 million people worldwide fall ill with tuberculosis (TB). However, currently, only around 7 million of them are identified – while the others are missed. Of the nearly 2 million deaths each year most are preventable with existing treatments, if diagnosed early, but diagnostic gaps in TB remain greater than for any other infectious disease.
There is an urgent need for TB tools and diagnostic technologies that can not only detect disease but can also identify strains that are resistant to the TB medications that are available. Containing the emergence of TB drug resistance is critical if we are to have a chance to beat the disease while the medicines that we have still work.
The introduction of automated real-time PCR-based technologies (i.e., GeneXpert®) improved TB case-detection and reduced diagnostic delay. Many studies conducted since then have contributed to both an understanding of the test’s limitations and the need for better tests to achieve the post-2015 TB targets of the World Health Organization (WHO). Even more importantly, the studies highlighted the need for optimized implementation strategies for novel tests and improved linkage to treatment.
Next-generation tests need to be placed at the point-of-care at microscopy centre level, fully integrated in the diagnostic and treatment network, connectivity enabled, more sensitive and able to perform expanded drug susceptibility testing (DST). Additionally, people living with HIV (PLHIV) are not well served by sputum-based diagnostics and non-traditional specimen-types (such as urine, oral swabs, and stool) and test technologies (such as the FujiLAM assay) have shown promise to improve diagnosis in this population.
TB-CAPT includes a series of clinical trials in Tanzania, Mozambique, and South Africa that will evaluate the impact of diagnostic interventions on outcomes, including the effects of expanding TB testing strategies to PLHIV. The trials have been designed to consider local epidemiology, as well as existing infrastructure, and will compare new strategies with current standards of care.
