Helicobacter Pylori Infection
Conditions
Brief summary
This study was a Phase 1, single-center, randomized, double-blind, placebo-controlled, multiple ascending dose study to evaluate the safety, tolerability, pharmacokinetics, and preliminary Helicobacter Pylori eradication efficacy of TNP-2198 capsules.
Interventions
TNP-2198 capsules/placebo were administered orally twice daily (BID, at 7:00 ± 1 hour in the morning and 19:00 ± 1 hour in the evening) in the fasted state for consecutive 14 days, and the last dose was taken at 7:00 am (±1 hour) on Day 15 in the fasted state, and breakfast or dinner should not be taken within 30 minutes after each dose.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Adverse Events(AEs) | up to 17 days | The percentage of subjects with at least one AEs. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Area Under the Plasma Concentration-Time Curve from the First Dose Extrapolated to Infinity (AUC0-∞) | Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15 | Plasma concentrations of TNP-2198 were measured by a specific and validated assay. Plasma Pharmacokinetics (PK) parameters of TNP-2198 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods. |
| Area Under the Plasma Concentration-Time Curve from the First Dose to the Last Measurable Concentration (AUC 0-last) | Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15 | Plasma concentrations of TNP-2198 were measured by a specific and validated assay. Plasma PK parameters of TNP-2198 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods. |
| Maximum Observed Plasma Concentration (Cmax) of TNP-2198 | Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15 | Plasma concentrations of TNP-2198 were measured by a specific and validated assay at specified time points |
