Official title: Anti-Helicobacter Pylori Therapy With Dexlansoprazole MR-Based Concomitant Quadruple Therapy- A Prospective Randomized Trial

Background:

Recommended proton pump inhibitor (PPI)-clarithromycin-amoxicillin or metronidazole treatment for 7 to14 days is the first choice treatment for H pylori infection. The eradication rate of the standard triple therapy has generally declined to unacceptable levels (i.e., 80% or less) recently because the increasing incidence of clarithromycin-resistant strains of H. pylori. Standard triple therapies should be abandoned in the areas with clarithromycin resistance ≥ 20%. The investigators have proven that 7-day Concomitant therapy can achieve a promising success rate of >90 % in the presence of clarithromycin resistance. However, high dose PPI is needed with a dosage of twice daily but when a dual delayed release formulation PPI in capsules for oral administration (Dexlansoprazole MR), a once daily dose may be needed only. The capsules contain dexlansoprazole in a mixture of two types of enteric-coated granules with different pH-dependent dissolution profiles. It suppresses gastric acid secretion via inhibition of the proton pump in the gastric parietal cell, which blocks the final step of acid production. Thus, it improves acid suppression and offer benefits over conventional single release PPI formulations. by prolonging optimal plasma concentration and create a favorable condition H. pylori eradication

Aim:

The efficacy of Dexlansoprazole MR-based concomitant quadruple therapy

Methods:

Two hundred and two consecutive H. pylori-infected participants are randomly assigned to a 7-day Dexlansoprazole MR-based non-bismuth quadruple therapy (Dexlansoprazole MR 60 mg qd.,clarithromycin 500 mg bid., amoxicillin 1 g bid. and metronidazole 500 mg bid. for 7 days) or a 7-day lansoprazole-based non-bismuth quadruple therapy (Lansoprazole 30 mg bid. , clarithromycin 500 mg bid., amoxicillin 1 g bid. and metronidazole 500 mg bid. for 7 days). Participants are asked to return at the 2nd week to assess drug compliance and adverse events. Repeated endoscopy with rapid urease test, histological examination is performed at the 8th week after the end of anti- H. pylori therapy. If participants refuse follow-up endoscopy, urea breath tests are conducted to assess H. pylori status. The rates of eradication are analyzed by intention-to-treat and per-protocol analysis.

What is being measured

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

  1. The rates of H.pylori eradication

    The primary outcome variables were the rates of eradication. Chi-square test with or without Yates correction for continuity and Fisher's exact test were used when appropriate to compare the major outcomes between groups. A P value less than 0.05 was considered statistically significant.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Dexlan, Amoxicillin and Clarithromycin 500mg in people with Helicobacter Pylori Infection, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

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 6 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 14 May 2019. 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 Taiwan. 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.

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?

The rates of H.pylori eradication (time frame: 8 weeks). 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 NCT03829150, 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 14 May 2019.
