Summary

The purpose of this study is to assess the efficacy, safety and tolerability of a combination of moxifloxacin, PA-824, and pyrazinamide treatments with varying doses and treatment lengths from 4 to 6 months in subjects with drug-sensitive (DS) pulmonary TB compared to standard HRZE treatment. This study will also assess the efficacy, safety and tolerability of a combination of moxifloxacin, PA-824, and pyrazinamide treatments after 6 months of treatment in subjects with multi drug-resistant (MDR) pulmonary TB compared to a combination of moxifloxacin, PA-824, and pyrazinamide treatments in DS-TB subjects.

Clinical Details

Official title: A Phase 3 Open-Label Partially Randomized Trial to Evaluate the Efficacy, Safety and Tolerability of the Combination of Moxifloxacin Plus PA-824 Plus Pyrazinamide After 4 and 6 Months of Treatment in Adult Subjects With Drug-Sensitive Smear-Positive Pulmonary Tuberculosis and After 6 Months of Treatment in Adult Subjects With Multi-Drug Resistant, Smear-Positive Pulmonary Tuberculosis.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Incidence of combined bacteriologic failure or relapse of clinical failure at 12 months from start of therapy.

Secondary outcome:

Incidence of bacteriologic failure or relapse or clinical failure at 24 months from the start of therapy as a confirmatory analysis.

The rate of change in time to culture positivity (TTP) over time in liquid culture MGIT in sputum, represented by the model‐fitted log(TTP) results as calculated by the regression of the observed log(TTP) results over time.

Time in days to sputum culture conversion to negative status in liquid culture (MGIT) through the treatment period to be explored as a potential biomarker of definitive outcome.

Proportion of subjects with sputum culture conversion to negative status in liquid culture (MGIT) at 4, 8, 12 and 17 weeks to be explored as a potential biomarker of definitive outcome.

Clinical laboratory safety measurements of hematology and chemistry, including observed and change from baseline.

Trough plasma concentrations will be used to evaluate the effects of baseline subject covariates on trial drug pharmacokinetics and associated bacteriological endpoints.

resistant to isoniazid) AND

- either newly diagnosed for TB or have a patient history of being untreated for

at least 3 years after cure from a previous episode of TB. If they are entered into the trial due to being sensitive to rifampicin by rapid sputum based test, however on receipt of the rifampicin resistance testing using an indirect susceptibility test in liquid culture this shows they are rifampicin resistant, they will be:

- Excluded as late exclusions;

- Possibly replaced as determined by the sponsor.

6. MDR‐TB treatment arm subjects should be resistant to rifampicin by rapid sputum based test (may be sensitive or resistant to isoniazid). 7. A chest x-ray which in the opinion of the investigator is compatible with pulmonary TB. 8. Be of non‐childbearing potential or using effective methods of birth control, as defined below: Non‐childbearing potential:

- Subject ‐ not heterosexually active or practice sexual abstinence; or

- Female subject or male subjects female sexual partner ‐ bilateral oophorectomy,

bilateral tubal ligation and/or hysterectomy or has been postmenopausal with a history of no menses for at least 12 consecutive months; or

- Male subject or female subjects male sexual partner ‐ vasectomised or has had a

bilateral orchidectomy minimally three months prior to screening; Effective birth control methods:

- Double barrier method which can include a male condom, diaphragm, cervical cap, or

female condom; or

- Female subject: Barrier method combined with hormone‐based contraceptives or an

intra‐uterine device for the female patient.

- Male subjects' female sexual partner: Double barrier method or hormone‐based

contraceptives or an intra‐uterine device for the female partner. and are willing to continue practising birth control methods and are not planning to conceive throughout treatment and for 12 weeks (male subjects) or 1 week (female subjects) after the last dose of trial medication or discontinuation from trial medication in case of premature discontinuation. (Note: Hormone‐based contraception alone may not be reliable when taking IMP; therefore, Exclusion Criteria: 1. Any non TB related condition (including myasthenia gravis) where participation in the trial, as judged by the investigator, could compromise the well-being of the subject or prevent, limit or confound protocol specified assessments. 2. Being or about to be treated for Malaria. 3. Is critically ill and, in the judgment of the investigator, has a diagnosis likely to result in death during the trial or the follow-up period. 4. TB meningitis or other forms of extrapulmonary tuberculosis with high risk of a poor outcome, or likely to require a longer course of therapy (such as TB of the bone or joint), as judged by the investigator. 5. History of allergy or hypersensitivity to any of the trial IMP or related substances, including known allergy to any fluoroquinolone antibiotic, history of tendinopathy associated with quinolones or suspected hypersensitivity to any rifampicin antibiotics. 6. For HIV infected subjects any of the following:

- Karnofsky score <60%;

- Received intravenous antifungal medication within the last 90 days;

- WHO Clinical Stage 4 HIV disease.

7. Resistant to fluoroquinolones (rapid, sputum - based molecular screening tests). If

they are entered into the trial due to being sensitive to fluoroquinolones by rapid sputum based test, however on receipt of the fluoroquinolones resistance testing using an indirect susceptibility test in liquid culture this shows they are fluoroquinolones resistant, they will be:

- Excluded as late exclusions;

- Possibly replaced as determined by the sponsor.

rapid, sputum - based molecular pyrazinamide resistance screening test result. On

receipt of the result, if they are resistant, they will be:

- Excluded as late exclusions;

- Possibly replaced as determined by the sponsor. MDR-TB treatment arm subjects

may not be entered prior to receipt of the rapid, sputum - based molecular

pyrazinamide resistance screening test result showing they are sensitive to pyrazinamide. 9.
