About this study

Official title: The Efficacy and Safety of Ilaprazole/Doxycycline-based Bismuth-containing Quadruple Therapy on Hp Infected Duodenal Ulcers: A Randomized, Parallel-controlled Multi-center Study

Helicobacter pylori (Hp) infection is one of the important causes of gastrointestinal diseases, including gastritis, peptic ulcer, and malignancies, nd the eradication of Hp can effectively cure or prevent these diseases. Now, owing to the increasingly serious antibiotic resistance, Hp eradication rate is, however, becoming decreased. In order to improve the eradication rate of Hp, clinicians pay great attention to choose more effective treatment.

Ilaprazole Enteric-Coated Tablets is a new generation of proton pump inhibitor (PPI). Previous research found that Ilaprazole had a more prolonged half-life and higher suppression of gastric acid secretion. In addition, its metabolism is not significantly influenced by CYP2C19, compared to the available PPIs. Doxycycline is in the tetracycline antibiotic class, has a stronger antibacterial force than tetracycline and its antibacterial spectrum is basically the same as tetracycline and doxycycline, so far, it is not widely used. Preliminary observations showed that Ilaprazole/Doxycycline-based quadruple therapy was effective in treating Hp infection, with less adverse reactions and good compliance with patients.

In this study, a multi-center, randomized, parallel controlled trial will be conducted in 7 hospitals in Hunan Province, China, to observe the clinical efficacy and safety of the Bismuth-containing quadruple therapy with Ilaprazole, Doxycycline, Furazolidone and Bismuth Potassium Citrate in the treatment of Hp infected duodenal ulcer. It is expected to complete 200 effective cases, including 100 cases in the experimental group and 100 cases in the control group.

What is being measured

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

  1. The eradication rate of H. pylori infection

    Evaluated by 13C-urea breath test (13C-UBT), 14C-urea breath test (14C-UBT), or Pathological examination.

    Measured: Visit period 3 (After day 56)

Secondary outcomes (6)
  1. The healing rate of duodenal ulcer(s)

    Duodenal ulcer healing rate is defined as the percentage of participants with complete healing of ulcer (according to Sakita-Fukutomi classification) under endoscope.

    Measured: Visit period 2 (day 28±1)

  2. Number of duodenal ulcer(s)

    Confirmed by endoscope.

    Measured: Visit period 2 (day 28±1)

  3. Maximum diameter of duodenal ulcer(s)

    Confirmed by endoscope (cm).

    Measured: Visit period 2 (day 28±1)

  4. Surrounding inflammation and(or) erosion of duodenal ulcer(s)

    Confirmed by endoscope.

    Measured: Visit period 2 (day 28±1)

  5. Incidence of bleeding

    Confirmed by endoscope.

    Measured: Visit period 2 (day 28±1)

  6. Improvement of gastric symptoms

    Improvement is defined as the total change from baseline symptoms scores of Symptom Rating Scale(Includidng 9 items: Pain in day, Pain in night, Burning in day, Burning in night, Acid reflux in day, Acid reflux in night, Nausea and vomiting, Belching, Abdominal distension. Depending on severity and frequency, scale ranges from 0-3 points.).

    Measured: Screening period (day -3~0), Visit period 1 (day 14±1), Visit period 2 (day 28±1)

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?

The eradication rate of H. pylori infection (time frame: Visit period 3 (After day 56)). 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 2 Mar 2022.
