Note that all sites routinely test Rifampin resistance in all people newly diagnosed to have TB disease, but do not test routinely for susceptibility to Levofloxacin unless Rifampin resistance is detected.

Tuberculosis Preventive Treatment (TPT) is given to healthy people and needs to be safe;\n2. Tuberculosis Preventive Treatment (TPT) with shorter regimens are superior with respect to acceptance, completion, and costs;\n3. 4 months of Rifampin 10mg\u002Fkg (4R10) is the safest regimen, but is completed by \\\u003C80% of patients;\n4. The safety of 2 months of Rifampin 20mg\u002Fkg (2R20) is similar to that of 4 months of Rifampin 10mg\u002Fkg (4R10), but completion is a concern;\n5. 1-month regimens have promising efficacy;\n6. Safety and tolerability must be carefully assessed with comparisons to 4 months of Rifampin 10mg\u002Fkg (4R10), and head-to-head with each other.\n\nOBJECTIVES: The investigator will use a Bayesian adaptive Phase 2 randomized open-label trial design to test at least three experimental Tuberculosis Preventive Treatment (TPT) regimens to identify at least one regimen of ≤2 months duration that has non-inferior safety, completion, and tolerability in adults and children relative to the reference Tuberculosis Preventive Treatment (TPT) regimen. The shortest, safest, and best tolerated regimen identified in this Phase 2 trial will be tested for effectiveness and efficacy in a Phase 3 trial.\n\nSpecific Tuberculosis Preventive Treatment (TPT) regimens (All are daily and self-administered) Reference: Rifampin at a dose of 10 mg\u002Fkg\u002Fday for 4 months (4R10); Experimental: 1) Rifampin at 20 mg\u002Fkg\u002Fday for 2 months (2R20); (2) one month Levofloxacin and Rifapentine (1LP). At a later stage a 3rd experimental regimen will be selected and added: one another novel 1-2-month regimen identified from pre-clinical and clinical studies.
