Brief Summary

To evaluate the efficacy, safety and tolerability at 8 weeks (2-months), 52 weeks (12-months), and 104 Weeks (24-months) post the start of the following treatment regimens in participants with: Drug Sensitive TB (DS-TB) patients given BPaMZ for 17 Weeks ( or 4 months) vs. Standard HRZE/HR treatment given for 26 weeks (or 6 months) and Drug Resistant TB (DR-TB) patients given BPaMZ for 26 Weeks (or 6 months)

Detailed Description

Phase 2c multi-center, open-label, partially randomized clinical trial in DS-TB and DR-TB participants.

All participants in the below arms will have follow-up for a period of 104 weeks (24 months) from the start of therapy.

Participants with Drug Sensitive TB (DS-TB):

Participants with DS-TB will be randomized to one of two treatment arms. These participants will receive either BPaMZ daily for 17 weeks (4 months), or HRZE/HR combination tablets daily for 26 weeks (6 months). participants will be stratified for co-infection with human immunodeficiency virus (HIV) and cavitation.

Participants with Drug Resistant TB (DR-TB):

Participants with DR-TB will be assigned to receive BPaMZ daily for 26 weeks (6 months).

Primary Outcome Measures
NameTimeMethod
Number of Participants With Culture Negative Status by 8 WeeksDays 0-56 (8 weeks)

Culture negative status is achieved when a participant produces at least two negative culture results at different visits (at least 7 days apart) without an intervening positive culture result for M.tb.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Bacteriologic Failure or Relapse or Clinical Failure (Unfavorables) at 52 Weeks From Start of Therapy (12 Months)52 weeks after start of therapy

Unfavorable status:

1. Participants not classified as having achieved or maintained culture negative status when last seen

2. Participants previously classified as having culture negative status who, following the end of treatment, have two positive cultures without an intervening negative culture

3. Participants who had a positive culture not followed by at least two negative cultures when last seen

4. Participants dying from any cause during treatment, except from violent or accidental cause, not including suicide

5. Participants definitely or possibly dying from TB related cause during the follow-up phase

6. Participants requiring an extension of their treatment beyond that permitted by the protocol a restart or a change of treatment for any reason except reinfection or pregnancy

7. Participants lost to follow up or withdrawn from the study before end of treatment

Time to Culture Negative StatusDuring treatment (17 or 26 weeks)

Culture conversion is a diagnostic criteria indicating the point at which samples taken from a patient infected with a tuberculosis can no longer produce tuberculosis cell cultures, that point is considered culture negativity
