Randomized Controlled Trial Multicenter Study
Safety, immunogenicity, and efficacy of the candidate tuberculosis vaccine MVA85A in healthy adults infected with HIV-1: a randomised, placebo-controlled, phase 2 trial.
HIV-1 infection is associated with increased risk of tuberculosis and a safe and effective vaccine would assist control measures. We assessed the safety, immunogenicity, and efficacy of a candidate tuberculosis vaccine, modified vaccinia virus Ankara expressing antigen 85A (MVA85A), in adults infected with HIV-1. ⋯ European & Developing Countries Clinical Trials Partnership (IP.2007.32080.002), Aeras, Bill & Melinda Gates Foundation, Wellcome Trust, and Oxford-Emergent Tuberculosis Consortium.

WHO estimates that 9 million people developed active tuberculosis in 2013 and 1·5 million people died from it. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis continue to spread worldwide with an estimated 480,000 new cases in 2013. Treatment success rates of MDR and XDR tuberculosis are still low and development of new, more effective tuberculosis drugs and adjunct therapies to improve treatment outcomes are urgently needed. ⋯ We review the latest WHO guidelines and global recommendations for treatment and management of drug-sensitive and drug-resistant tuberculosis, and provide an update on new drug development, results of several phase 2 and phase 3 tuberculosis treatment trials, and other emerging adjunct therapeutic options for MDR and XDR tuberculosis. The use of fluoroquinolone-containing (moxifloxacin and gatifloxacin) regimens have failed to shorten duration of therapy, and the new tuberculosis drug pipeline is sparse. Scale-up of existing interventions with increased investments into tuberculosis health services, development of new antituberculosis drugs, adjunct therapies and vaccines, coupled with visionary political leadership, are still our best chance to change the unacceptable status quo of the tuberculosis situation worldwide and the growing problem of drug-resistant tuberculosis.
