Any type of resource available online.
Pretomanid, an oral nitroimidazooxazine antimycobacterial agent administered as part of the BPaL (bedaquiline, pretomanid and linezolid) and BPaMZ (bedaquiline, pretomanid, moxifloxacin and pyrazinamide) regimens, has been developed by the Global Alliance for TB Drug Development (TB Alliance) under license from Novartis, for the treatment for tuberculosis (TB). TB Alliance has licensed Mylan to manufacture and commercialize pretomanid for use as part of the BPaMZ and BPaL regimens. The license is non-exclusive in low- and middle-income countries and exclusive in high-income markets. Pretomanid, as part of the BPaL regimen, was recently approved in the USA under the Limited Population Pathway for Antibacterial and Antifungal Drugs (LPAD) pathway for the treatment of extensively drug-resistant (XDR) TB and treatment-intolerant or non-responsive multidrug-resistant (MDR) TB. Pretomanid is also under regulatory review in the EU. This article summarizes the milestones in the development of pretomanid leading to this first regulatory approval.
