Interim CDC Guidance for a Novel TB Regimen

  • CDC recommends the 4-month RPT-MOX regimen as an option for treating patients aged ≥12 years and body weight ≥40 kg with pulmonary TB caused by organisms that are not known or suspected to be drug-resistant and who have no contraindications to this regimen. The 4-month daily treatment regimen consists of an intensive phase composed of 8 weeks of daily treatment with rifapentine, moxifloxacin, INH, and PZA, followed by a continuation phase of 9 weeks of daily treatment with rifapentine, moxifloxacin, and INH. The drugs are administered once daily with food, 7 days per week, for a total of 119 treatment doses. Similar to the standard 6-month regimen, at least 5 of 7 weekly doses should be administered under DOT. Ref: MMWR Morb Mortal Wkly Rep 2022;71:285. PDF of guidance here.
