About this study

Official title: Clinical Study on Bifidobacterium Quadruple Live Bacteria Tablets (Si Lian Kang) Reducing the Incidence Rate of Adverse Reactions in Helicobacter Pylori Quadruple Eradication Therapy and on the Effects of Gastrointestinal Flora

The purpose of this clinical trial is to evaluate the clinical efficacy of Bifidobacterium quadruple live bacteria tablets (Si Lian Kang) on reducing the incidence rate of adverse reactions of Helicobacter pylori quadruple eradication therapy and its influence on gastrointestinal flora.

Read the detailed description

Bismuth agent quadruple therapy (including bismuth agent and proton pump inhibitor combined with two antibiotics) is the first-line strategy to eradicate Helicobacter pylori in China. However, it may cause a series of adverse reactions, such as nausea, diarrhea, abdominal pain, constipation, and abnormal taste, etc., which leads to a decrease in patient compliance, thereby affecting the treatment effect. Many studies have found that adding probiotics to traditional Helicobacter pylori eradication therapies increase eradication rates and reduce the side effects of the treatment. Bifidobacterium tetrad live bacteria tablet is a compound microecological preparation composed of bifidobacterium infantis, lactobacillus acidophilus, enterococcus faecalis and bacillus cereus. This study aims to observe the clinical efficacy of Bifidobacterium quadruple live bacteria tablets (Si Lian Kang) on reducing the incidence rate of adverse reactions in Helicobacter pylori quadruple eradication therapy and on the effects of gastrointestinal flora.

Bifidobacterium tetrad live bacteria tablet plus Helicobacter pylori quadruple eradication therapy, Bifidobacterium tetrad live bacteria tablet placebo plus Helicobacter pylori quadruple eradication therapy

What is being measured

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

  1. the total incidence rate of digestive tract related adverse reactions

    The patient diary cards (including Bristol stool classification, diarrhea, constipation, abdominal pain, abdominal distension, belching, nausea, vomiting, loss of appetite and changes in taste) are filled in daily from the -14th day to 28th day. The above contents are recorded weekly from the 29th to182th day. to calculate the total incidence rate of digestive tract related adverse reactions mentioned above

    Measured: baseline, 28 days, 182days

Secondary outcomes (7)
  1. the incidence rate of various digestive tract related symptoms

    to calculate incidence rate of various digestive tract related symptoms including diarrhea, constipation, and other symptoms mentioned above

    Measured: baseline, 28 days, 182days

  2. duration of various digestive tract related symptoms

    to calculate duration of various digestive tract related symptoms including diarrhea, constipation, and other symptoms mentioned above

    Measured: baseline, 28 days, 182days

  3. stool frequency

    to evaluate the defecation frequency of diarrhea and constipation

    Measured: baseline, 28 days, 182days

  4. changes in intestinal flora

    to evaluate the changes of intestinal flora during the clinical study period

    Measured: baseline, 14 days, 28 days, 70 days, 182days

  5. changes in gastric flora

    20 patients are enrolled in the experiment group and control group respectively. Mucosal samples (one gastric antrum and one gastric body) are taken by gastroscopy before treatment. Gastroscope was reexamined 6 weeks after probiotics or placebo withdrawal (the 70th day), and mucosal samples (one gastric antrum and one gastric body) are taken.

    Measured: baseline, 70 days

  6. Helicobacter pylori eradication rate

    to evaluate the results of 13C-urea breath test

    Measured: 70 days

  7. adverse events

    Adverse events are assessed during the clinical study period.

    Measured: 28 days,182 days

A Phase 4 study testing Bifidobacterium tetrad live bacteria tablet plus Helicobacter pylori quadruple eradication therapy in people with Helicobacter Pylori Eradication, run by Hangzhou Grand Biologic Pharmaceutical, Inc. at 2 sites in China.

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 4 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 4 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. 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 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.

What does the primary outcome measure?

the total incidence rate of digestive tract related adverse reactions (time frame: baseline, 28 days, 182days). 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.
