• 1 other identifier: TNP-2092-04
• Study Type: interventional
• Target: 20
• Locations: 1 country
• Sites: 1

Brief Summary

A phase 1, single-center, double-blind, randomized, placebo-controlled clinical trial to evaluate the safety and tolerability, pharmacokinetics, and preliminary efficacy of multiple administrations of TNP-2092 Capsules in combination with Rabeprazole Sodium Enteric-coated Tablets in asymptomatic healthy subjects with Helicobacter pylori infection

Conditions

Helicobacter Pylori Infection

Outcome Measures

Primary Outcomes (4)

• Area Under the Plasma Concentration Versus Time Curve Extrapolated to Infinity (AUC0-inf)

  Plasma concentrations of TNP-2092 were measured by a specific and validated assay. Plasma Pharmacokinetics (PK) parameters of TNP-2092 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods

  Within 15 minutes before the morning dose of Rabeprazole Sodium Enteric-coated Tablets, and 20 minutes, 50 minutes, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 8, 10 and 12 hours after the morning dose of Rabeprazole Sodium Enteric-coated Tablets

• Area Under the Plasma Concentration Versus Time Curve from 0 to the Last Measurable Concentration (AUC0-t)

  Plasma concentrations of TNP-2092 were measured by a specific and validated assay. Plasma PK parameters of TNP-2092 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods.

  Within 15 minutes before the morning dose of Rabeprazole Sodium Enteric-coated Tablets, and 20 minutes, 50 minutes, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 8, 10 and 12 hours after the morning dose of Rabeprazole Sodium Enteric-coated Tablets

• Maximum Observed Plasma Concentration (Cmax) of TNP-2092

  Plasma concentrations of TNP-2092 were measured by a specific and validated assay at specified time points

  Before administration (within 60 minutes), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 36, 48 and 72 hours after administration]

• Percentage 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
