A new drug combination containing rifapentine and moxifloxacin has finally broken the 6-month treatment barrier for drug-susceptible pulmonary tuberculosis, requiring only 4 months to produce a disease-free state at 1 year in most patients.
In open-label, phase 3, multinational trial, Doctors pitted 4-month regimens containing 1200 mg of rifapentine taken once daily with or without 400 mg of moxifloxacin taken daily against a standard 6-month regimen of rifampin, isoniazid, pyrazinamide, and ethambutol. For both 4-month treatments, rifapentine replaced rifampin, and for one of them, moxifloxacin also replaced ethambutol.
