Brief Summary:
Tuberculosis remains a concerning health problem, with Mycobacterium Tuberculosis (MTB) now causing more deaths than acquired immune deficiency syndrome (AIDS). GSK3036656 is a compound with a novel mechanism of action under development for the treatment of tuberculosis. It suppresses protein synthesis in MTB by selectively inhibiting the enzyme Leucyl t-ribose nucleic acid (RNA) synthetase. Thus, this study will investigate the early bactericidal activity, safety and tolerability of GSK3036656 in up to four sequential cohorts of subjects with rifampicin-susceptible tuberculosis. The primary objective of this dose-escalation study is to establish the anti-tuberculosis effect of GSK3036656 on serial colony forming units (CFU) counts of MTB in sputum over 14 days of therapy. Subjects in each cohort will be randomized in 3:1 ratio to one of two treatments: either GSK3036656 or standard-of-care (RIFAFOUR® e-275) regimen. The approximate duration of the study for an individual subject will be 5 weeks, including 1 week of screening, 2 weeks of treatment period and another 2 weeks of final follow-up visit.

Primary Outcome Measures :
  1. Change in log10 Colony Forming Units (CFU) Per (/) Milliliter (mL) of Direct Respiratory Sputum Samples From Baseline to Day 14 [ Time Frame: Baseline and up to Day 14 ]
    The Early Bactericidal Activity was determined by change in log10CFU/mL of sputum over the period Baseline to Day 14. Log(CFU) was calculated as: Log(CFU/mL)=log10(mean[Total count 1:Total Count 2]*2*5*10^Dilution); where total counts 1 and 2 were bacterial counts from plates 1 and 2 respectively; *2 represents the 1:1 dilution of the original specimen and *5 represents the 0.2 mL (200 microliter) inoculation of the specimen; Dilution is the dilution factor for that plate. Baseline (Day 0) was defined as the mean of Day -2 and Day -1; if data was available at only one of these timepoints then that value was used as Baseline.


Secondary Outcome Measures :
  1. Change in log10 CFU/mL of Direct Respiratory Sputum Samples From Baseline to Day 2 [ Time Frame: Baseline and up to Day 2 ]

Baseline (Day 0) was defined as the mean of Day -2 and Day -1; if data was available at only one of these timepoints then that value was used as Baseline.

  2. Change in log10 CFU Per mL of Direct Respiratory Sputum Samples From Day 2 to Day 14 [ Time Frame: Day 2 to Day 14 ]

The TTP was measured in the Mycobacterial Growth Indicator Tube (MGIT) automated liquid culture system of time to positivity of Mycobacterium tuberculosis from an overnight sputum collection. Time to sputum-culture positivity was the time between sample inoculation and detection of mycobacterial growth in the mycobacterium growth indicator tube. Baseline (Day 0) was defined as the mean of Day -2 and Day -1; if data was available at only one of these timepoints then that value was used as Baseline.

  4. Change in log10 TTP From Baseline to Day 2 [ Time Frame: Baseline and up to Day 2 ]
    The Early Bactericidal Activity was determined by change in TTP per mL sputum over the period Baseline to Day 2. The TTP was measured in the MGIT automated liquid culture system of time to positivity of Mycobacterium tuberculosis from an overnight sputum collection. Time to sputum-culture positivity was the time between sample inoculation and detection of mycobacterial growth in the mycobacterium growth indicator tube. Baseline (Day 0) was defined as the mean of Day -2 and Day -1; if data was available at only one of these timepoints then that value was used as Baseline.

  5. Change in log10 TTP From Day 2 to Day 14 [ Time Frame: Day 2 to Day 14 ]
    The Early Bactericidal Activity was determined by change in TTP per mL sputum over the period Day 2 to Day 14. The TTP was measured in the MGIT automated liquid culture system of time to positivity of Mycobacterium tuberculosis from an overnight sputum collection. Time to sputum-culture positivity was the time between sample inoculation and detection of mycobacterial growth in the mycobacterium growth indicator tube.

    Urine samples were collected to assess urine occult blood and urine protein. The dipstick test gave results in a semi-quantitative manner, and results for urinalysis parameters were recorded as no change/decreased and increase to abnormal for urine occult blood and protein indicating proportional concentrations in the urine sample. 'No change/decreased' means no change from Baseline or a value less than the Baseline value. 'Increase to abnormal' means an increase from the Baseline value that is considered as an abnormal value. Baseline value is the latest assessment prior to Day 1 dose with a non-missing value, including those from unscheduled visits. Data for worst-case post Baseline is presented.

The PCI range for vital signs were: systolic blood pressure (SBP) (lower: <85 and upper: >160 milliliter of mercury [mmHg]); diastolic blood pressure (DBP) (lower: <45 and upper: >100 mmHg); heart rate (lower: <40 and upper: >110 beats per minute [bpm]); respiratory rate (lower: 10 and upper: 28 breaths per minutes) and temperature (lower: <35 and upper: >37.9 degrees Celsius). Participants were counted in the worst-case category that their value changed to (low, within range or no change, or high), unless there was no change in their category. Participants whose value category was unchanged (e.g. High to High), or whose value became within range, were recorded in the "To w/in Range or No Change category". Participants were counted twice if the participant had values that changed "To Low" and "To High".

  24. Number of Participants With Worst Case Post-Baseline Abnormal Electrocardiogram (ECG) Findings [ Time Frame: Up to Day 28 (follow-up visit) ]
    Twelve lead ECGs were obtained using an ECG machine that automatically calculated the heart rate and measured PR, QRS, uncorrected QT and QT duration corrected for heart rate by Fridericia's formula (QTcF) intervals. Abnormal findings were categorized as clinically significant and not clinically significant. Clinically significant abnormal laboratory findings are those which are not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition. Data for number of participants with abnormal clinically significant ECG findings for worst case post-Baseline has been presented.

  25. Change From Baseline in QT Interval Corrected Using Fridericia's Formula (QTcF) [ Time Frame: Baseline (Day 1, Pre-dose) and at Day 14 ]
    Twelve-lead ECGs were obtained to QTcF Interval and measured QT duration corrected for heart rate by Fridericia's formula interval. Baseline value was the latest assessment prior to Day 1 dose with a non-missing value, including those from unscheduled visits and the mean of the triplicate measurements at any given time point was used as the value for that time point. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit (Day 14) value.
