TB Alliance's REMox TB program leverages ACTG sites to advance testing of improved TB treatments

Durban, South Africa— 15 November 2011 The TB Alliance announces the launch of a collaboration with the National Institute of Allergy and Infectious Diseases' (NIAID) AIDS Clinical Trial Group (ACTG) to conduct and help complete a Phase III clinical trial testing potentially faster-acting tuberculosis (TB) treatments. Few clinical trials for TB have been conducted under modern GCP/GCLP standards in the past 40 years, and the infrastructure to support invigorated global TB drug research is lacking, especially in resource-limited settings where the majority of TB cases are found. The partnership between the NIAID's ACTG and TB Alliance joins available resources with the urgent need for TB clinical research capacity to accelerate testing of new therapies that can benefit both the HIV/AIDS and TB communities.

TB and HIV/AIDS are sometimes called "the dual epidemic" because they can be fatally synergistic. TB is the leading infectious killer of people with HIV/AIDS, especially in sub-Saharan Africa. Globally, one-third of the 33 million people living with HIV/AIDS are also infected with the bacterium that causes TB. New and improved TB drugs are desperately needed to treat patients suffering from HIV/TB co-infection.

The TB Alliance is currently enrolling patients in REMox TB, a global Phase III clinical trial, which is testing two four-month moxifloxacin-containing treatment regimens for drug-sensitive (DS) TB against the standard six-month therapy. Moxifloxacin has the potential to be the first new drug to treat DS-TB in more than 40 years, offering the potential for a shorter therapy for the millions of TB and TB/HIV co-infected patients. In order to help increase trial capacity to complete enrollment in the trial, four ACTG clinical trials units will participate in REMox TB.

"This collaboration is a perfect example of how innovative and efficient resource sharing can benefit all parties involved —in this case, the TB and the HIV/AIDS community, and especially those co-infected with TB and AIDS," said Dr. Mel Spigelman, President and CEO, TB Alliance. "With this collaboration, ACTG enhances our collective capacity to more quickly evaluate new TB drugs and regimens, which will result in improved therapies being available sooner for all TB patients, including those co-infected with HIV."

The 4 new clinical trial sites that will participate in REMox TB are located in Africa, and include the UKZN-Durban International Clinical Trials Unit, UKZN‐CAPRISA‐HIV/AIDS CTU, and Soweto CTU at PHRU in South Africa; and the Center for Infectious Disease Research at the Kalingalinga ACTG Clinic in Zambia. Enrollment has begun in multiple sites in Durban and will expand to the other sites in the coming months.

"The new and expanding commitment by the U.S. National Institutes of Health to apply 21st century science to one of humanity's oldest scourges, TB, by tackling the co-epidemics of HIV and TB where they are the worst, in many African settings, has the promise of accelerating progress against both diseases," said Mark Harrington, Executive Director, Treatment Action Group. "Activists, people with TB or HIV, researchers, and providers all welcome the expanded involvement of the NIH-funded ACTG in studying new TB drugs and regimens, bringing closer the prospect that we can eliminate them both in this century."
