Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants with a Favorable Treatment Outcome at the End of Treatment Percentage of participants with a favorable treatment outcome at the end of treatment will be reported. A participant's outcome will be classified as favorable if their last 3 culture results by the end of treatment are negative unless they have previously been classified as unfavorable. These 3 cultures must be taken on separate visits; the latest of which being no more than 8 weeks prior to the end of treatment. At the end of treatment (Week 40)
Secondary Percentage of Participants with a Favorable Treatment Outcome at 48 Weeks Post the End of Treatment Percentage of participants with a favorable treatment outcome at 48 weeks post the end of treatment will be reported. A participant's outcome will be classified as favorable if their last 3 culture results by the end of treatment are negative unless they have previously been classified as unfavorable. These 3 cultures must be taken on separate visits; the latest of which being no more than 8 weeks prior to the end of treatment. At 48 weeks post the end of treatment (Week 88)
Secondary Percentage of Participants Achieving Treatment Success at the end of Treatment Percentage of participants achieving treatment success at the end of treatment will be reported. Treatment success is achieved if participants completed their prescribed tuberculosis (TB) treatment; or if their last 3 culture results are negative by the end of treatment, these 3 cultures must be taken on separate visits and should be after the initial 6-month treatment period. At the end of treatment (Week 40)
Secondary Percentage of Participants with a Modified Favorable Treatment Outcome at the end of Treatment and at 48 Weeks Post end of Treatment Percentage of participants with a modified favorable treatment outcome at the end of treatment and at 48 weeks post end of treatment will be reported. A participant's treatment outcome will be classified as modified favorable if their last 2 culture results by the end of treatment are negative unless they have previously been classified as unfavorable. These 2 cultures must be taken on separate visits; the latest of which being no more than 8 weeks prior to the end of treatment. At the end of treatment (Week 40) and at 48 weeks post end of treatment (Week 88)
Secondary Percentage of Participants Experiencing All-cause Mortality Percentage of participants experiencing all-cause mortality will be reported. Up to Week 88
Secondary Percentage of Participants Experiencing Grade 3 or Greater Treatment-emergent Adverse Events (TEAEs) During Study Treatment and Follow-up Percentage of participants experiencing grade 3 or greater TEAEs during study treatment and follow-up will be reported. An adverse event (AE) is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. TEAEs are defined as any event that begins or worsens in severity after initiation of study drug through to the end of study. An assessment of severity grade will be made using the following 5 general categorical descriptors based on division of acquired immunodeficiency syndrome (AIDS) grading for AE severity assessment. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening, and Grade 5= Death. During study treatment and follow-up (From Week 1 up to Week 88)
Secondary Percentage of Participants Experiencing TEAEs Percentage of participants experiencing TEAEs will be reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. TEAEs are defined as any event that begins or worsens in severity after initiation of study drug through to the end of study. From Week 1 up to Week 88
Secondary Percentage of Participants with TB Relapses and Re-infections During the Treatment-free Follow-up Phase Percentage of participants with TB relapses and re-infections during the treatment-free follow-up phase will be reported. During the treatment-free follow-up phase (Up to 48 weeks)
Secondary Percentage of Participants Whose Isolates Develop Resistance to Bedaquiline and Other Drugs Used in the Regimen Percentage of participants whose isolates develop resistance to bedaquiline and other drugs used in the regimen will be reported. Up to Week 88
