Phase 2b trial results of novel TB regimen show potential to shorten treatment

This photomicrograph reveals Mycobacterium tuberculosis bacteria using acid-fast Ziehl-Neelsen stain; Magnified 1000 X. The acid-fast stains depend on the ability of mycobacteria to retain dye when treated with mineral acid or an acid-alcohol solution such as the Ziehl-Neelsen, or the Kinyoun stains that are carbolfuchsin methods specific for M. tuberculosis.

A new tuberculosis (TB) drug regimen designed to improve options for TB therapy eliminated more bacteria from sputum than standard therapy and did so at a faster rate, according to data from a phase 2b clinical trial published today in The Lancet. These results are published just as the global phase 3 clinical trial, designed to bring this regimen through the last stage of testing, has begun.
