Summary

This is a phase 2B/C, open label platform study that will compare the efficacy, safety of experimental regimens with a standard control regimen in participants with newly diagnosed, drug sensitive pulmonary tuberculosis. In stage 1, participants will be randomly allocated to the control or one of the 2 rifampicin-containing experimental regimens in the ratio 1:1:1. In stage 2, the experimental arm 4 containing BTZ-043 will be added. The allocation ratio will be changed to co-enrol the remaining participants in arms 1- 3 simultaneously with arm 4 in a ratio of 1:1:1:2. When arms 1-2 are fully enrolled and arm 4 is not, further participants will be randomized 1:1 to control and experimental arm 4. Not all countries will participate in stage 2. In stage 3, participants will be allocated in parallel to control arm treatment (now designated arm 7) or the experimental arms 5 and 6, favouring arm 5, 2:1:1 over arms 6 and control. This stage will start after completion of recruitment in the stages 1 and 2. Enrolment of participants into arm 5 will proceed following review of data from the ENABLE/UNITE-03 (NCT06748937), non-clinical safety data and after endorsement by the DSMB. Thus, arm 5 recruitment might start after arms 6 and 7, which may require an increase in the control arm sample size to ensure controls are recruited concomitantly.
