H.Pylori Infection
Conditions
Brief summary
A multi-center, randomized, double-blind, bismuth-containing quadruple active comparator-controlled Phase 3 clinical study to evaluate the efficacy and safety of Rifasutenizol in combination with rabeprazole and amoxicillin in the primary treatment of participants with H. pylori infection using an adaptive design with sample size re-estimation.
Detailed description
Subjects will be randomly assigned to test group or control group at a 1:1 ratio stratified by study site, and will receive Rifasutenizol capsules, rabeprazole sodium enteric-coated tablets, amoxicillin capsules combined with clarithromycin placebo tablets and bismuth potassium citrate placebo capsules (test group), or bismuth-containing quadruple regimen of amoxicillin capsules, clarithromycin tablets, rabeprazole sodium enteric-coated tablets and bismuth potassium citrate capsules combined with Rifasutenizol placebo capsules (control group) for 14 consecutive days. carbon-13 (13C) UBT will be performed 4-6 weeks after the last dose to evaluate the eradication effect of H. pylori.

Time frame: Day 14: 30 minutes before and 1, 2, 3, 4, 5, 6, 7, 8, 10, 12 hours after Rifasutenizol (TNP-2198) administration
Population: All randomized participants who have received Rifasutenizol (TNP-2198) and have at least one pharmacokinetic parameter data.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Test Group | Maximum Observed Plasma Concentration (Cmax) of Rifasutenizol (TNP-2198) on Day 14 | 504 ng/mL | Standard Deviation 187 |
Safety by Assessment of the Number of Participants With Adverse Events (AEs)
An Adverse Event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An Adverse Event can therefore be any unfavorable and unintended sign (including abnormal laboratory values or abnormal clinical test results), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as Adverse Events.
Time frame: up to 4-6 weeks after the last dose of the study drugs
Population: All the participants who have been randomized into groups and received at least one dose of study drugs.
| Arm | Measure | Value (COUNT_OF_PARTICIPANTS) |
|---|---|---|
| Test Group | Safety by Assessment of the Number of Participants With Adverse Events (AEs) | 131 Participants |
| Control Group | Safety by Assessment of the Number of Participants With Adverse Events (AEs) | 184 Participants |
