Clinical Trial 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)

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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Culture Negative Status by 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.	Days 0-56 (8 weeks)
Secondary	Number of Participants With Bacteriologic Failure or Relapse or Clinical Failure (Unfavorables) at 52 Weeks From Start of Therapy (12 Months)	Unfavorable status: Participants not classified as having achieved or maintained culture negative status when last seen; Participants previously classified as having culture negative status who, following the end of treatment, have two positive cultures without an intervening negative culture; Participants who had a positive culture not followed by at least two negative cultures when last seen; Participants dying from any cause during treatment, except from violent or accidental cause, not including suicide; Participants definitely or possibly dying from TB related cause during the follow-up phase; 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a restart or a change of treatment for any reason except reinfection or pregnancy; Participants lost to follow up or withdrawn from the study before end of treatment	52 weeks after start of therapy
Secondary	Time to Culture Negative Status	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	During treatment (17 or 26 weeks)
