TNP-2092 Capsules in asymptomatic healthy subjects with Helicobacter pylori infection.  
2) 
To evaluate the pharmacokinetic characteristics of multiple oral dose-escalation

Methodology 
This study is a single-center, randomized, double-blind, placebo-controlled, dose-ascending 
multiple-dose-administration study. The aim of this study is to evaluate the safety, tolerability, and 
pharmacokinetic profile of TNP-2092 Capsules in asymptomatic healthy subjects with 
Helicobacter pylori infection, and to explore the preliminary efficacy of TNP-2092 Capsules in 
eradicating Helicobacter pylori. 
 
In this study, three dose groups of 100 mg, 300 mg and 600 mg will be set up. The drug will be 
taken twice a day for 14 consecutive days, and last dose on the morning of Day 15. Fifteen 
subjects in each of the 100 mg and 300 mg dose groups will be randomized at a ratio of 4:1, with 
12 subjects receiving the investigational product and 3 receiving placebo. Ten subjects in the 600 
mg dose group will be randomized at a ratio of 4:1, with 8 subjects receiving the investigational 
product and 2 subjects receiving placebo. 
 
During the trial, blood samples will be collected from the subjects at the specified time points for 
pharmacokinetic analysis. In the 300 mg group, urine and stool samples will be collected from 7 
subjects who are first enrolled in the group for metabolic transformation study. 
 
Plasma sample: 
 
Blood samples are collected at different time points. Day 1: before the first administration (within 
60 minutes), 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after administration; Day 15: before 
administration (within 60 minutes), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48 and 72 hours after 
administration; Days 2-14: before the first administration every day (within 60 minutes), the 
trough concentration is measured to monitor the complete pharmacokinetic changes. 
 
Urine sample (300 mg BID dose group - for 7 subjects who are first enrolled in the group only): 
 
Urine samples are collected before administration and 0-6 hours, 6-12 hours, 12-24 hours, 24-48 
hours and 48-72 hours after administration on Day 15 for metabolic transformation study.

This study is an early phase exploratory clinical trial, the sample size is not based on statistical 
hypothesis test. but based on the assessment of safety, PK, and preliminary efficacy in line with similar 
trails. The sample size of 15 patients in both of the 100 mg and 300 mg dose groups, and 10 patients in 
the 600 mg group are also appropriate for the purpose of the exploration of the PK profile, safety, and 
efficacy of TNP-2092 capsules. 
 
Population for analyses 
 
Full Analysis Set (FAS): all the subjects who have been randomized into groups. 
 
Safety Analysis Set (SS): all the subjects who have been randomized into groups and received at 
least one dose of study drug. 
 
PK Concentration Analysis Set (PKCS): all the subjects who have been randomized into groups, 
received at least one dose of study drug, and have at least one evaluable blood drug concentration. 
 
PK Parameter Analysis Set (PKPS): all subjects who have been randomized into groups, have 
received at least one dose of study drug, and have at least one evaluable pharmacokinetic 
parameter. 
 
Interim analysis 
No interim analysis is planned. 
 
PK analysis 
Pharmacokinetic analysis will be based on the PKPS. Pharmacokinetic concentration and 
parameters will be subjected to descriptive analysis by dose group. The mean and individual 
drug-time curves will be shown graphically. Numbers will include individual values and mean 
values. In addition, individual and mean dose standardization parameters will be plotted against 
the dose to evaluate whether there are any obvious trends. 
 
Safety and tolerability analysis 
It will be based on the SS. Physical examination results and changes, laboratory test results and 
changes, vital signs results and changes, as well as ECG results and changes will be descriptive 
analyzed by dose group and planned time point. The abnormal results of these examinations will 
also be listed. Adverse events (AEs) will be coded using the Medical Dictionary for Regulatory 
Activities (MedDRA) and summarized by treatment group and dose according to the system 
organ class (SOC) and preferred terms (PTs). In addition, serious adverse events (SAEs) and AEs 
leading to dropout and death will be listed separately. 
 
Efficacy analysis 
The preliminary Helicobacter Pylori eradication efficacy will be analyzed based on FAS. The 
number and percentage of subjects with 14C UBT negative at the follow-up visit will be listed by 
dose group. Fisher's exact test was used for comparison of percentages between groups (if 
infeasible for data reasons, summarize only). For all measurements, the baseline values and 
changes from baseline will be summarized by dose group and visit. Changes from baseline will be 
compared between groups by visit using analysis of covariance model, with baseline value as 
covariate and treatment group as fixed effect factors. Missing values will be imputed using last 
observation carry forward (LOCF). Sensitivity analysis will be performed using mixed model for 
repeated measures (MMRM), with baseline value and treatment group as fixed effect factors. An 
unstructured covariance matrix will be preferred in the model, if not fitted, other suitable 
covariance matrix would be used.

Abbreviations: PK = pharmacokinetics; Pre = before the first daily dose; Post = after the first daily dose; 
1. 
If a subject prematurely terminates the study after taking the drug, subsequent designated visits should be completed. 
2. 
Pregnancy test may be repeated during the course of the study, if deemed necessary by the investigator. 


3. 
UBT is performed before breakfast on Day 16. 
4. 
If multiple assessments are performed at the same time, it is recommended to collect samples/data in the following order in the non-emergency state (but subject to 
actual clinical practice): PK samples, ECGs, and vital signs; and then all the other assessments. ECGs, blood pressure, and pulse should be measured after the subject has 
rested for approximately 5 minutes. The subjects are required to fast overnight for 10 hours before blood biochemistry test; water was deprived for 1 hour before 
administration and 2 hours after administration. 
5. 
If hematology, urinalysis, blood chemistry, and coagulation tests were performed within 48 hours of screening, the results could be used as baseline values and no 
additional tests were required. 
6. 
If stool routine test was performed within 7 days of screening, the result could be used as the baseline value and no additional tests were required. 
7. 
If no stool specimen was collected on the specified day, the situation should be stated, and no additional collection was required. 
8. 
If no stool specimen was collected on that day, no additional collection was required. 
9. 
Adverse events should be followed up until they are resolved or until the investigator assesses the subject as having returned to baseline. 
10. Sampling/testing time (hours) was relative to the time of the first dose on the very day of the study. 
11. Sampling/testing time (hours) was relative to the dosing time on Day 15 of the study. 
12. Subjects received the drug orally twice daily after breakfast and dinner (the meals should be finished within 30 minutes and the drug should be administered 30 minutes 
after the start of the meal) with 240 mL of warm water, 12 hours apart. The initial dose was 100 mg twice daily after meals. After the administration for the 100 mg dose 
group and the evaluation of safety and tolerability were completed, the next dose group would be tested according to the principle of ascending until the maximum dose 
was reached or the predefined indication for study suspension occurred. 
13. The last dose was given 30 minutes after the start of breakfast on Day 15. 
14. The 12-lead ECG and vital signs measured before administration on D1 were used as baseline values. 
15. Subjects only had breakfast that day. 
16. Subjects were required to be in a fasting condition in the morning for the follow-up examinations at the clinical study site. 
17. Hepatitis B tests included hepatitis B virus surface antigen (HBsAg), hepatitis B virus surface antibody (HBsAb), hepatitis B virus e antigen (HBeAg), hepatitis B virus 
e antibody (HBeAb), and hepatitis B virus core antibody (HBcAb). The hepatitis C test is a hepatitis C virus antibody test. 
18. Specimens were collected from the first 7 subjects enrolled in the 300 mg dose group.
