About this study

Official title: Role of Lignin in Treatment of Helicobacter Pylori Infection: A Double-blind Placebo-controlled Study

The goal of this clinical trial is to learn if drug hydrolyzed lignin works to treat H pylori infection in adults. It will also learn about the safety of drug lignin n the sitting of H pylori infection, and if it halts the side effects associated with H pylori triple therapy. The main questions it aims to answer are:

  • Does drug hydrolyzed lignin improve the H pylori eradiation rate when it is added to the standard triple therapy used in treatment of H pylori?
  • What medical problems do participants experience when taking drug hydrolyzed lignin? Researchers will compare drug hydrolyzed lignin to a placebo (a look-alike substance that contains no drug) to see if drug hydrolyzed lignin works to treat H pylori.

Participants will:

  • Take drug hydrolyzed lignin or a placebo every day for 2 weeks beside the standard triple therapy
  • Visit the clinic once every 1 week for checkup and questionnaire filling
  • Check for H pylori eradication after treatment

What participants receive

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

  • Hydrolyzed LigninDrug

    The drug will be supplied randomly to the group I

  • PlaceboOther

    Will be supplied randomly to Group II

Study groups in NCT07246681
Study groupRoleWhat they receive
Group IActive comparatorThis is the study group who will receive the standard triple (proton pump inhibitor, amoxicillin, clarithromycin) therapy plus the hydrolyzed lignin 400 mg
Receives: Drug: Hydrolyzed Lignin
Group IIPlacebo comparatorThis is the study group who will receive the standard triple therapy (proton pump inhibitor, amoxicillin, clarithromycin) plus the placebo identical in color, shape, and taste with the hydrolyzed lignin
Receives: Other: Placebo

What is being measured

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

  1. Eradication rate

    How much the H pylori eradication rate following the treatment

    Measured: 2 weeks of continuous treatment, followed by 2 weeks of treatment and then testing again for presence\absence of the infection

Secondary outcomes (1)
  1. Safety profile

    The side effects related to the used medications (triple therapy and lignin)

    Measured: up to 4 weeks (2 weeks active treatment and 2 weeks after treatment)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Hydrolyzed Lignin in people with HELICOBACTER PYLORI INFECTIONS, run by Zagazig University at 1 site in Egypt.

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 5 inclusion and 4 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 Oct 2026. 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 Egypt. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Eradication rate (time frame: 2 weeks of continuous treatment, followed by 2 weeks of treatment and then testing again for presence\absence of the infection). 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 NCT07246681, 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 1 Oct 2026.
