About this study

Helicobacter pylori (H. pylori) is one of the most common chronic infections worldwide. The mode of transmission of H. pylori is through the fecal-oral or oral-oral routes.

Chronic gastritis has been linked to helicobacter pylori (H. pylori) infection. Peptic ulcer disease, gastric adenocarcinoma, and gastric lymphoma are all linked to this condition .

In Egypt, a high prevalence of H. pylori infections has been reported, ranging from 70% in the general population , 73% among school children , up to 88% in patients with chronic active HCV .

In 2007, the American College of Gastroenterology estimated that the cure rate for H. pylori infections was 70-85 percent with the use of a proton pump inhibitor (PPI), clarithromycin, and amoxicillin or metronidazole .

children with H. pylori infection do not have severe digestive symptoms. pylori infection represents a key factor in the pathogenesis of duodenal ulcer and chronic gastritis in children. In addition, H. pylori infection has also been reported to have extra-digestive consequences .

A recent comprehensive evaluation found that sequential and conventional triple treatment had a cure rate of 84% .

The infected macrophage is unable to create enough 1,25-(OH)2D to control the synthesis of AMP cathelicidin when it is vitamin D deficient .

vitamin D has a powerful systemic antibacterial impact by enhancing the activity of monocytes and macrophages. Most illnesses seem to benefit from a vitamin D-rich condition .

Vitamin D-deficient subjects might be more prone to developing H. pylori infection .

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lansoprazole, amoxicillin and clarithromycin in people with Helicobacter Pylori Infection, run by Assiut University.

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 1 inclusion and 2 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: opening soon, as of the sponsor's last update on 9 May 2025. Status can change between updates, so confirm with the study contact before making plans.

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 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?

This study is still under way. Results are not available in the source record yet.

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?

cure rate after treatment (time frame: 3 months). 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 9 May 2025.
