NIH expands key tuberculosis research program

The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is expanding its Tuberculosis Research Units (TBRU) program in an effort to drive innovation in tuberculosis (TB) research. NIAID is awarding up to $15.2 million in fiscal year 2015 and as much as $105.3 million over seven years to fund four institutions that will act as a collaborative TBRU network.

A critical component of NIAID’s tuberculosis research, the TBRU program was established in 1994 with the aim of integrating basic and clinical research to study TB in countries where the disease is endemic. For the past 20 years, one TBRU operated under a contract with Case Western Reserve University with study sites in Uganda, Brazil, the Philippines and South Africa and active research collaborations worldwide. This TBRU has helped to identify biomarkers that define the various stages of infection and disease, contributed to best practices for TB clinical trials, and examined factors to help understand why some people infected with the disease-causing Mycobacterium tuberculosis do not develop TB.

Although the number of individuals becoming sick or dying from TB worldwide has slowly declined in recent years, the global burden of the disease remains substantial. About one-third of the world’s population carries latent TB bacteria, according to the World Health Organization. In 2013, an estimated 9 million people became ill with TB and 1.5 million died from the disease. More than 500,000 children developed TB in 2013 and 80,000 died from the infection, according to WHO.

“Progress is being made in the international fight against TB; however, the disease remains entrenched in many countries, especially those in Sub-Saharan Africa,” said NIAID Director Anthony S. Fauci, M.D. “New investment in the TB Research Units will help us to improve our understanding of this ancient disease and how best to diagnosis, treat and ultimately prevent it.”

During the past 15 years, a sustained effort in TB research has translated to a new pipeline of drug, vaccine and diagnostic candidates. In 2012, the Food and Drug Administration (FDA) approved the first new tuberculosis drug in more than 40 years. However, a limited understanding of the stages of TB disease has hampered transformation in optimal management of the disease.

By integrating epidemiology, immunology, and microbiology the four awardee institutions will work together to examine how Mycobacterium tuberculosis interacts with the human host and the immune system to cause disease. Through animal studies and clinical research, the TBRU program will focus on TB latency and persistence and their relation to active TB disease in humans.

NIAID conducts and supports research — at NIH, throughout the United States, and worldwide — to study the causes of infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses. News releases, fact sheets and other NIAID-related materials are available on the NIAID website athttp://www.niaid.nih.gov.

About the National Institutes of Health (NIH): NIH, the nation's medical research agency, includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. NIH is the primary federal agency conducting and supporting basic, clinical, and translational medical research, and is investigating the causes, treatments, and cures for both common and rare diseases.
