About this study
Official title: Double-blind, Placebo-controlled, Randomized Study for Assesment of the Efficiency and Safety Quadruple Therapy for Helicobacter Pylori Infection With or Without the Addition of Saccharomyces Boulardi Probiotic
This study assesses the effect of quadruple therapy for H. pylori, with the addition of probiotics Saccharomyces boulardii. In addition, he assesses whether this combination reduces the frequency of adverse effects of eradication therapy, and whether it affects the compliance.
Read the detailed description
Standard triple therapy for H. pylori infection proved to be insufficiently effective, primarily due to antibiotics resistance.Therefore, the latest Maastricht consensus suggests using bismuth-quadruple or non-bismuth-quadruple therapy, in regions with high clarithromycin resistance. The addition of probiotics with eradication therapy has never become a standard treatment. However, the Maastricht consensus suggest that the addition of probiotics could increase the effectiveness of quadruple therapy.
The study was designed as a prospective, double-blind, randomized, case-control intervention study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Result of urea breath test (Eradication of H.pylori)

Measured: baseline to 8 weeks after the introduction of the therapy
Secondary outcomes (2)
Side effects of eradication therapy
Number and severity of adverse events of standard eradication therapy
Measured: baseline to 8 weeks after the introduction of the therapy
Compliance of eradication therapy
Patient successfully completed prescribed therapy
Measured: baseline to 8 weeks after the introduction of the therapy

The record says: status not confirmed, as of the sponsor's last update on 25 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.
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.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Miodrag Krstic, MD, PhD (+381113615575, krstic.miodrag61@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Result of urea breath test (Eradication of H.pylori) (time frame: baseline to 8 weeks after the introduction of the 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 25 Jun 2019; AzTrials last refreshed its copy on 8 Nov 2026.
