What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to stable culture conversion to negative in liquid media
Time Frame: Day 01- Week 26
|
The primary efficacy endpoint of arms 1 and 2 will be time to stable culture conversion to negative in liquid media defined as the time from enrolment to the first of two negative weekly sputum cultures without an intervening positive culture in liquid media, in comparison to arm 3. The efficacy of BTZ-043 will be evaluated by measuring the change in mycobacterial load over time on treatment as quantified by time to positivity in BD MGIT 960® liquid culture described by non-linear mixed-effects methodology, in comparison to arm 3. |
Day 01- Week 26
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Relapse - free survival at 12 months after randomization
