Participant Flow

This study was initiated on 28 October 2021 (first signed informed consent) with the date of last participant who completed last study visit on 04 Sep 2023. A total of 156 participants were screened. Of these, 76 participants were randomized to 1 of 5 arms, and subsequently received at least 1 dose of the study drug. The remaining 80 participants were considered to have been screen failures.

PRIMARY outcome

Timeframe: Week 0 - Week 16

Population: Intent to Treat Population; all randomized participants in the groups to which they were randomly assigned and who have taken at least one dose of study treatment.

The efficacy of DZD was evaluated by measuring the change in mycobacterial load over time on treatment as quantified by TTP (Time to positive) in BD MGIT960® liquid culture described by non linear mixed effects methodology. A population PK model was developed using NONMEM version 7.4.1. DZD PK is well-described by a two-compartment model with first-order absorption, first-order elimination and a proportional residual error. The final model included allometric scaling based on FFM.

Population: Intent to Treat Population; all randomized participants in the groups to which they were randomly assigned and who have taken at least one dose of study treatment.

The efficacy of DZD was evaluated by measuring the change in mycobacterial load over time on treatment as quantified by TTP (Time to positive) in BD MGIT960® liquid culture described by non linear mixed effects methodology. A population PK model was developed using NONMEM version 7.4.1. DZD PK is well-described by a two-compartment model with first-order absorption, first-order elimination and a proportional residual error. The final model included allometric scaling based on FFM.

Summary of Changes in Mycobacterial Load Over Time on Treatment as Quantified by Time to Positivity in BD MGIT960® Liquid Media - Intent to Treat Population Sputum samples were collected for BD MGIT960® Liquid Media culture at all time points during the treatment and follow-up phases, and this table shows culture results, which are reported as: Positive, Negative, Contaminated, Missing. Note: Contaminated cultures are shown as contaminated for the purpose of the overall result but are counted as missing for calculating summary statistics. The data recorded as 'Positive for MTB Complex with Contamination' are included as 'Positive' for MGIT result. However, the data from mean and median calculations for TTP (Time to positive) due to contamination.

Timeframe: Week 0 - Week 16

Population: Intent to Treat Population; all randomized participants in the groups to which they were randomly assigned and who have taken at least one dose of study treatment.

The efficacy of DZD was evaluated by measuring the change in mycobacterial load over time on treatment as quantified by time to positivity (TTP) in BD MGIT 960® liquid culture described by nonlinear mixed-effects methodology. Sputum samples were collected for BD MGIT960® Liquid Media culture at all time points during the treatment and follow-up phases, and this table shows TTP results.

Timeframe: Week 0 - Week 16

Population: Intent to Treat Population; all randomized participants in the groups to which they were randomly assigned and who have taken at least one dose of study treatment.

Culture conversion was defined as 2 negative cultures without an intervening positive culture. Time was measured as time on treatment until the first negative culture (up to Week 16 Visit). 'Converted by Week x' shows proportion converted by day corresponding to end of each week, e.g., Week 2 = Day 14.

Participants receive the following medication for the duration of 16 weeks together with food. * Delpazolid was dosed 1200 mg orally once daily * Bedaquiline was dosed as per the licensed dose: 400 mg orally once daily for the first 14 days, then 200 mg three times a week. * Delamanid was dosed as per the licensed dose: 200 mg orally twice daily doses of 100 mg. * Moxifloxacin was dosed as per the licensed dose: 400 mg orally once daily Delpazolid: Delpazolid is not licensed yet. Current experience in humans upto Phase IIA. Dose according to randomization to dosing arms 2-5. Bedaquiline, Delamanid, Moxifloxacin: These three licensed drugs form the backbone of a new regimen to which delpazolid is added in arms 2-5.
