About this study
Official title: Efficacy of Tailored for Helicobacter Pylori Rescue Treatment Based on Antimicrobial-susceptibility Testing
With increasing antibiotic resistance and unsatisfactory results of empiric eradication regimens, tailored therapy may be the best choice to achieve high efficacy for rescue treatment. This study aimed to evaluate the eradication rates, safety, and compliance of antimicrobial susceptibility-based tailored therapy for rescue treatment in patients with Helicobacter pylori infection.
- Conditions
- Helicobacter Pylori Infection
- Being tested
- esomeprazole, bismuth Potassium Citrate, amoxicillin, clarithromycin, metronidazole

What is being measured
The primary outcome is the main question the study is designed to answer.
Helicobacter pylori eradication rate
Six weeks after completion of therapy, H. pylori eradication was assessed by ¹³C-urea breath test. Eradication was defined as negative result from urea breath test (<4‰) (4‰ as the cutoff value).
Measured: Six weeks after completion of therapy
Secondary outcomes (2)
Rate of adverse effects
The subjects were asked to grade the severity of adverse events according to their influence on daily activities, experienced as "mild" (transient and well tolerated), "moderate" (causing discomfort and partially interfering with daily activities), or "severe" (causing considerable interference with daily activities).
Measured: Within 7 days after completion of therapy
Compliance rate
Compliance was defined as poor when they had taken less than 80% of the total medication.
Measured: Within 7 days after completion of therapy

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing esomeprazole, bismuth Potassium Citrate and amoxicillin in people with Helicobacter Pylori Infection, run by Shanghai Jiao Tong University School of Medicine at 1 site 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 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 7 Aug 2018. 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 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. 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?
Helicobacter pylori eradication rate (time frame: Six weeks after completion of therapy). 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 NCT03413020, 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 7 Aug 2018.
