Being tested
TNP-2198, TNP-2198 Placebo

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TNP-2198Drug

    Also called Rifasutenizol

    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.

  • TNP-2198 PlaceboDrug

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Adverse Events(AEs)

    The percentage of subjects with at least one AEs.

    Measured: up to 17 days

Secondary outcomes (3)
  1. Area Under the Plasma Concentration-Time Curve from the First Dose Extrapolated to Infinity (AUC0-∞)

    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.

    Measured: Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15

  2. Area Under the Plasma Concentration-Time Curve from the First Dose to the Last Measurable Concentration (AUC 0-last)

    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.

    Measured: Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15

  3. Maximum Observed Plasma Concentration (Cmax) of TNP-2198

    Plasma concentrations of TNP-2198 were measured by a specific and validated assay at specified time points

    Measured: Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TNP-2198 in people with Helicobacter Pylori Infection, run by TenNor Therapeutics (Suzhou) Limited 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 8 inclusion and 22 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 13 Oct 2023. 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. 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?

Incidence of Adverse Events(AEs) (time frame: up to 17 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06081712, which also lists 1 linked publication.

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 13 Oct 2023; AzTrials last refreshed its copy on 7 Nov 2026.
