This strikes me as one of the stranger choices in human history. Humans, a species that simply can never have enough, somehow decided that five or six anti-TB drugs would be plenty. Why? New classes of drugs to treat bacterial infections are not easy to find, but we know they are possible to find. In the last couple decades as economic incentives have shifted, we’ve been able to develop powerful new medications to treat TB, including bedaquiline and delamanid.
