Study Endpoints
Primary Endpoints
Change from Baseline in log10 CFU of Mycobacterium tuberculosis (MTB) (per milliliters of respiratory sputum samples)
Baseline and up to Day 14

The extended early bactericidal activity of each treatment group will be determined by the change from Baseline to Day 14 in log10CFU.

Change in log10 Colony Forming Units (CFU) Per (/) Milliliter (mL) of Direct Respiratory Sputum Samples From Baseline to Day 14
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.

Subjects will receive repeat single dose of GSK3036656 once daily over a period of 14 days. Dosing with food may also be done if there are PK or tolerability reasons making it preferable to dose in a fed state (dose will be given with a high fat meal.). The total dose may also be divided into 2 or 3 smaller doses administered within 24 hours on discretion of the GSK study team and the principal investigator. Appropriate dose and dose regimen will be selected on available safety, tolerability and PK data from preceding repeat dose cohorts from Part B. Subjects will be followed up to 2 weeks from the last dose.
Cohort 5- Placebo in Part BPLACEBO_COMPARATORDuring Part B (Cohort 5), Subjects will receive a single matching placebo once daily in morning on Day 1 after an overnight fast of at least 8 hours. Subjects will receive a placebo once daily over a period of 14 days. Dosing with food may also be done if the active treatment is given in a fed state (dose will be given with a high fat meal.). The total dose may also be divided into 2 or 3 smaller doses administered within 24 hours in a similar manner if divided for subjects receiving active treatment in the same cohort. Subjects will be followed up to 2 weeks from the last dose.
Cohort 6- GSK3036656 in Part BEXPERIMENTALDuring Part B (Cohort 6), Subjects will receive a single dose of GSK3036656 once daily in morning on Day 1 after an overnight fast of at least 8 hours. Subjects will receive repeat single dose of GSK3036656 once daily over a period of 14 days.
