• 
Screening, up to 10 days 
• 
Monotherapy, 14 days 
• 
Follow-up, 7 days 
Screening procedures are carried out within 10 days before randomization. 
Screening procedures can be carried out on an outpatient or inpatient basis. If the 
screening procedures are performed outpatiently, subjects are admitted to hospital 
on the day before the first dose of the study drugs. If the screening procedures are 
performed inpatiently, subjects stay hospitalized for the purpose of participation in 
the clinical study. 
Eligible subjects are randomized. During randomization, each subject is assigned a 
randomization number generated by the IWRS. Each patient is assigned to one of 
the following four groups based on the randomization number: 
• 
Group 1: subjects receive PBTZ169 capsules at a daily dose of 160 mg 
for 14 days as a monotherapy, after which the drug is discontinued, and 
standard antituberculosis therapy is prescribed (hereinafter, standard 
antituberculosis therapy is defined as the tuberculosis therapy provided 
for under Order of the Ministry of Health of the Russian Federation 
No. 951 dated December 29, 2014). Up to 15 subjects are planned to be 
randomized to this group. 
• 
Group 2: subjects receive PBTZ169 capsules at a daily dose of 320 mg 
for 14 days as a monotherapy, after which the drug is discontinued, and 
standard antituberculosis therapy is prescribed. Up to 15 subjects are 
planned to be randomized to this group. 
• 
Group 3: subjects receive PBTZ169 capsules at a daily dose of 640 mg 
for 14 days as a monotherapy, after which the drug is discontinued, and 
standard antituberculosis therapy is prescribed. Up to 15 subjects are 
planned to be randomized to this group. 
• 
Group 4: subjects receive isoniazid tablets at a standard daily dose of 
600 mg for 4 days as a monotherapy, after which standard 
antituberculosis therapy follows. Up to 7 subjects are planned to be 
randomized to this group. 
All study procedures are conducted in the subjects and documented under the 
randomization number.

Nocturnal sputum is collected from all subjects in the morning at V1. After that, 
every patient received the study drug (PBTZ169 or isoniazid) as a monotherapy for 
14 consecutive days. After 14 days of monotherapy (Day 15 of the study, V8), 
PBTZ169 is discontinued in Groups 1 to 3 (Day 14 being the day of the last 
PBTZ169 dose). Standard therapy is initiated 3 days after the monotherapy end date 
(Day 18 of the study, V10). Standard therapy drugs are resumed in Group 4 
(standard dose of isoniazid) without a break—that is, the day following the 
monotherapy end date (Day 15 of the study). Patient monitoring during clinical 
study is continued on a hospital basis and ended 7 days following the monotherapy 
end date. 
Venous blood samples are taken from all subjects in Groups 1, 2, and 3 (PBTZ169 
monotherapy) to measure PBTZ169 levels. Blood samples are drawn before the first 
doze of PBTZ169 (0 min time point) and later at the following time points after the 
first dose: in 0:20, 0:40, 1:00, 1:30, 2:00, 2:30, 3:00, 4:00, 6:00, 8:00, 10:00, 12:00, 
and 24:00 (hr:min). Blood samples are also taken before the last doze of PBTZ169 
(0 min time point) and later at the following time points after the last dose: after 
0:20, 0:40, 1:00, 1:30, 2:00, 2:30, 3:00, 4:00, 6:00, 8:00, 10:00, 12:00, 24:00, 48:00, 
and 72:00 (hr:min). 
All venous blood samples are kept in case any additional parameters have to be 
measured. 
Subjects are hospitalized throughout the monotherapy and follow-up periods. 
 
Number of subjects: It’s planned to randomize 52 eligible subjects for the study, 
namely 15 subjects in each PBTZ169 group and 7 subjects in the isoniazid group. 
The data of subjects who will receive at least one dose of the study drug and whose 
study drug concentrations are known will be processed in the final statistical analysis 
of efficacy and pharmacokinetics. 
The data of subjects of ITT population will be processed in the final statistical 
analysis of safety.

Statistical methods: 
Descriptive statistics will be provided for all demographics and other baseline 
characteristics, efficacy and safety parameters, and changes in them (if applicable) 
in the course of the study by means of assessment time points and treatment groups. 
Descriptive statistics for quantitative variables include mean value, standard 
deviation (SD), minimum and maximum values, and the number of valid 
observations. Qualitative data is presented as rates and percentages. 95% confidence 
intervals around point estimations are provided as well (where applicable). 
 
Efficacy analysis 
According to the EMA Guidance, early bactericidal activity (EBA) assessment 
should be based on determining the count of live mycobacteria in the patient's 
sputum during monotherapy with the drug. The primary method of determining 
mycobacterial count used is inoculating agar with sputum to count CFU/mL. The 
method is chosen as it is used as the primary method in nearly all studies assessing 
early bactericidal activity, which means it can be considered conventional [16-–19]. 
The method of quantitative PCR for counting mycobacterial cells in sputum is used 
as a secondary method for secondary analysis [23]. 
All assessments of log10 CFU/mL sputum, mycobacterial cell count estimates 
obtained with PCR, and their changes from baseline are tabulated by measurement 
points and treatment groups. 
In the primary analysis of treatment efficacy, changes from baseline in log10 
CFU/mL sputum (for agar inoculation) 14 days after the therapy start date are 
estimated. Changes in log10 CFU/mL sputum 2 and 7 days after the therapy start date 
are also estimated in the secondary analysis of treatment efficacy. Early bactericidal 
activity (EBA) is assessed as a change in log10 of CFU/mL of sputum specified for 
the treatment day [24] with a two-sided 95% confidence interval.  
Though sample size is estimated empirically disregarding formal comparisons 
between the two dose levels, the Kruskal–-Wallis test is used to compare the values 
for different dose levels of the study drug at a two-sided 5% significance level. 
The history of mean changes in log10 CFU/mL from baseline by assessment points 
is presented graphically by treatment groups. 
The Jonckheere- –-Terpstra test is used to identify the trend for the primary efficacy 
endpoint depending on the increase in dose level (increasing EBA0–-14 for increasing 
doses).  
A similar efficacy analysis (based on changes in log10 cells/mL) is carried out by 
determining mycobacterial cell count with quantitative PCR. 
Graphical methods and calculation of correlation coefficients between individual 
measurements obtained using the two quantification methods are used to analyze the

consistency of the results between the two methods of determining mycobacterial 
count. 
Only available measurements are used in efficacy analysis. No missing values are 
restored. The analysis is based on average values for each measurement point. An 
additional analysis at the maximum of two measurements is carried out (with the 
highest number of CFU or MBT DNA copies using agar inoculation and quantitative 
PCR, respectively). 
 
Safety analysis 
The MedDRA dictionary is used to code adverse events. The number (percentage) 
of patients with AEs and the number of AEs are tabulated by system organ class and 
preferred term as well as by study treatment, severity, and treatment group. Each 
patient is included within each system organ class and preferred term only once 
regarding the study treatment and maximum severity. 
Laboratory test values and their changes from baseline (at screening) following the 
administration of the study drug and "shift tables" based on reference values are 
tabulated by treatment groups and measurement points. 
The findings of ECG, vital sign assessment, and body temperature measurements 
are tabulated by study group for each measurement point, including changes from 
the most recent measurement made prior to dosing. 
Physical examination findings are presented descriptively by treatment group and 
measurement point. 
 
Pharmacokinetic analysis 
All concentration measurements after single and multiple dosing are tabulated by 
time point and treatment group and listed. Reasons are explained for any missing 
measurements and measurements not included in the pharmacokinetic analysis. 
Descriptive statistics for concentration measurements and PK parameters include the 
mean, standard deviation, the median, the minimum, the maximum, coefficient of 
variation (%), and the number of valid cases (N). Geometric means and geometric 
coefficient of variation are also presented for concentrations and PK parameters such 
as C and AUC. 
The actual values of sampling time are used to calculate individual values of PK 
parameters using the noncompartmental approach. The dependence of drug 
concentration on time is presented graphically for each individual patient based on 
actual sampling time. The descriptive statistics and average PK curves are presented 
based on the estimated sampling time points. Average and individual PK curves are 
presented on the arithmetic and logarithmic scale.

Pharmacokinetic and pharmacodynamic analysis 
An additional analysis is carried out to compare pharmacokinetic and 
pharmacodynamic parameters. Cmax,ss and AUC0–24,ss measured after multiple dosing 
after 14 days of therapy are used for early bacterial activity EBA0–14 and EBA2–14 as 
parameters for PK comparison. Cmax, Cmin, and AUC0–24, measured after the first dose 
administration are used for early bacterial activity EBA0–2. 
PK/PD indicators are compared using graphical representation (plotting pairs of 
individual values against on X and Y for each comparison of parameters X and Y) 
and by calculating coefficients of correlation within treatment group as well as in 
general. 
 
An interim analysis is to be carried out when at least 15 patients across all groups 
have completed the study. The interim analysis is not carried out since the study is 
terminated early.
