About this study

Official title: Visiting Staff, Division of Gastroenterology and Department of Internal Medicine, Mackay Memorial Hospital, Taipei, Taiwan

Helicobacter pylori (H. pylori) is an important causal factor of chronic gastritis, peptic ulcer disease, gastric cancer and gastric lymphoma. The World Health Organization classified H. pylori as a Group 1 carcinogen in 1994. Endoscopic examination is indicated to confirm the above diagnosis for patient with H. pylori infection. The eradication of H. pylori can reduce the recurrence rate of peptic ulcer disease and even has the potential to prevent gastric cancer. H. pylori is the most common chronic bacterial infection in humans. The prevalence of H. pylori is about 30-50% in the Western adult population. It is estimated that about 50% of people are infected with this bacterium in Taiwan.

Triple therapy which contains a proton pump inhibitor and two antibiotics among clarithromycin, amoxicillin, and metronidazole is the most commonly used regimen for H. pylori eradication. The treatment duration is 7 to 14 days. However, the eradication rate of standard triple therapy has fallen below 80% in many countries due to the worldwide increasing prevalence of antibiotic resistant strains.

Several strategies have been proposed to increase the eradication rate in the first line therapy or as a rescue therapy, including extending the treatment duration to 14 days, increasing the doses of antibiotics, the use of four or even five drugs regimen (sequential, concomitant, quadruple or quintuple therapy), and other antibiotics such as levofloxacin. However, these therapies may increase the side effects and costs of treatment, decrease the compliance of patients and increase the rate of worldwide antibiotic resistance steadily. The WHO has listed H. Pylori as one of 16 antibiotic-resistant bacteria that have the greatest threat to human health in February, 2017.

The most commonly used oral antibiotics for the treatment of H. pylori are Amoxicillin、Clarithromycin、Metronidazole、Levofloxacin and Tetracycline.

However, with the increasing rates of antibiotic-resistance for Clarithromycin and Metronidazole, the Clarithromycin and Metronidazole were replaced by Levofloxacin as a first line or second line treatment in some area. However, the eradication rate of Levofloxacin-containing triple therapy is suboptimal in many countries. The investigators aim to compare the efficacy of different formulation between Levofloxacin Powder and Levofloxacin Solution in the Intraluminal levofloxacin therapy, and to improve the eradication efficacy of one-week Levofloxacin-containing triple therapy via the Intraluminal therapy.

Read the detailed description

During the endoscopic examination, patient is sedated with intravenous Dormicum 5mg (5mg/1ml/amp), the vital signs will be closely monitored by physiological monitor (PHILIPS SureSigns VM6). The treatment will be terminated immediately if unstable vital sign detected or if patient asks for termination. Patients will receive tests to evaluate H. pylori colonization in the gastric cardia (UFT300) and duodenal bulb (CLO). With endoscope apparatus, the gastric mucus is irrigated with acetylcysteine solution and the pH value of gastric juice will be measured with the pH test strips before irrigation and after irrigation.

The investigators randomly assigned medicaments containing different formulation (powder or solution ) of levofloxacin to dispense on the surface of gastric mucosa and duodenal mucosa of duodenal bulb. After the intraluminal therapy, patients will rest for 30 to 60 minutes and go home if the effect of sedation subsided. Patients can take meal if no abdominal discomfort. C13-Urea breath test (UBT) will be used to assess the existence of H. pylori 6 weeks after the intraluminal therapy. Patients failed to achieve intraluminal eradication of H. pylori will be randomly assigned to 7-day or 14-day levofloxacin-containing triple therapy (levofloxacin 500 mg once daily, amoxicillin 1 g twice daily, and esomeprazole 40 mg twice daily). The C13-UBT will be used to assess the existence of H. pylori 6 weeks after the oral antibiotic therapy. The overall eradication rates of the intraluminal therapy plus the oral antibiotics therapies will be evaluated.

What is being measured

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

  1. Eradication rate of the intraluminal Levofloxacin therapy

    A Comparison of different formulation between Levofloxacin Powder and Levofloxacin solution

    Measured: C13-UBT will be used to assess the existence of H. pylori 6 weeks after the intraluminal therapy.

Secondary outcomes (3)
  1. Incidence of adverse effects of the intraluminal Levofloxacin therapy

    A Comparison of different formulation between Levofloxacin Powder and Levofloxacin solution

    Measured: within 7 days after finishing the intraluminal therapies

  2. Eradication rates of 7-day or 14-day levofloxacin-containing triple therapy

    A Comparison of the eradication rates of 7-day or 14-day levofloxacin-containing triple therapy after intraluminal therapy

    Measured: C13-UBT will be used to assess the existence of H. pylori 6 weeks after the levofloxacin-containing triple herapies.

  3. The overall eradication rate

    The overall eradication rates of the intraluminal therapy plus oral antibiotics therapies were evaluated.

    Measured: 3-6 months after finishing the intraluminal therapy

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levofloxacin film-coated tablet and Levofloxacin intravenous solution in people with Helicobacter Pylori Infection, run by Mackay 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 3 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 5 Feb 2021. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 of the intraluminal Levofloxacin therapy (time frame: C13-UBT will be used to assess the existence of H. pylori 6 weeks after the intraluminal therapy.). 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 5 Feb 2021.
