Recent progress in TB diagnostics and prevention approaches offers hope for future

In September 2018, the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH, issued its Strategic Plan for Tuberculosis Research, which outlined research priorities to reduce and ultimately end the burden of tuberculosis (TB). TB is a bacterial disease that has claimed the lives of more than a billion people in the past two centuries. Now, a new "Perspective" in The Journal of Infectious Diseases by NIAID Director Anthony S. Fauci, M.D., and other Institute officials summarizes recent progress in improved TB diagnostics, therapeutic regimens and prevention approaches that made 2019 a "banner year" for TB research. Therapeutics trials described by the NIAID authors include BRIEF TB/A5279, a Phase 3 clinical study demonstrating that a one-month course of two antibiotic drugs worked as well as a nine-month regimen of a single drug to prevent TB disease among adults and adolescents with HIV at risk of developing active TB. In June 2019, NIAID and the Eunice Kennedy Shriver National Institute of Child Health and Human Development, also part of NIH, launched the Phase 3 PHOENIx MDR-TB trial in 12 countries. PHOENIx MDR-TB (Protecting Households on Exposure to Newly Diagnosed Index Multidrug-Resistant Tuberculosis Patients) will compare two oral regimens for preventing active TB in adults, teens and children who are at high risk of infection because they live with adults who have multidrug-resistant TB. "Results from this innovative study will inform new TB prevention guidelines to avert the pain, disability and death associated with MDR-TB," Dr. Fauci and his coauthors write. Related Stories
