We are living in a time of great change and excitement in TB drug development. The last year has witnessed a number of epochal changes, including the approval and rollout of the most rapid test for TB ever discovered, the GeneXpert; the combination TB drug studies in the relapse mouse model of Eric Nuermberger and Jacques Grosset at Johns Hopkins with support from the TB Alliance; the progression of TMC207 into late phase II and of OPC67683 into phase III; and the first new regimen EBA study, NC-001 also from the Alliance.
