What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: 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.
Measured: 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
Measured: 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
Measured: Day 1 to Day 49

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing TNP-2092 capsules and Rabeprazole sodium enteric-coated tablets in people with Helicobacter Pylori Infection, run by TenNor Therapeutics Inc. at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area Under the Plasma Concentration Versus Time Curve Extrapolated to Infinity (AUC0-inf) (time frame: 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). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2024; AzTrials last refreshed its copy on 8 Nov 2026.
