About this study
Official title: The Phase 2 Study of FP-10, the Food Ingredient Derived From Milk Casein, on the Eradication Rates of Helicobacter Pylori by a Triple Therapy With Lansoprazole, Amoxicillin, and Clarithromycin
FP-10 is a food ingredient derived from milk casein. FP-10 can inhibit H. pylori to attach to the gastric epithelium. FP-10 has been made clear to decrease the intragastric urease activity (which is assumed to be produced by H. pylori) measured by the urea breath test. FP-10 can also detach H. pylori from gastric epithelium. We have hypothesized that FP-10 increases the eradication rates by a triple therapy with a proton pump inhibitor, amoxicillin, and clarithromycin.
Read the detailed description
- pylori -positive patients older than 15 years of age with gastritis, gastric ulcer, duodenal ulcer, or gastroduodenal ulcer are invited to participate in the study. These patients had endoscopically and histologically proven ulcers or active chronic gastritis and are all H. pylori-positive. Written informed consent to participation must be obtained from each patient before the study.
During gastroduodenoscopy, biopsy specimens obtained from both the antrum and the corpus of the greater curvature are subjected to the bacterial susceptibility to clarithromycin by culture test or measurements of 23S rRNA mutations at positions 2142 and 2143 (from adenine to guanine).
Patients are treated with 30 mg of lansoprazole bid, 200 mg of clarithromycin bid, and 750 mg of amoxicillin bid for one week. In addition, they take placebo bid, FP10 1 g bid, or FP-10 2 g bid (2 hour after breakfast and at the bed time) for the same one week. Administration of placebo, FP-10 1 g or FP-10 2 g are performed in a double blinded manner.
Eradication of H. pylori was confirmed by a 13C-urea breath test performed one month after eradication therapy. Throughout the study period, the investigators involved in the assessment of H. pylori eradication are blinded to susceptibility to clarithromycin H. pylori strains.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
FP-10 is a food ingredient derived from milk casein. FP-10 can inhibit H. pylori to attach to the gastric epithelium. FP-10 has been made clear to decrease the intragastric urease activity (which is assumed to be produced by H. pylori) measured by the urea breath test. FP-10 can also detach H. pylori from gastric epithelium. We have hypothesized that FP-10 increases the eradication rates by a triple therapy with a proton pump inhibitor, amoxicillin, and clarithromycin.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing FP-10 in people with Helicobacter Pylori, run by Hamamatsu University at 7 sites in Japan.
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 1 inclusion and 2 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 27 Jan 2006. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in Japan. 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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 Takahisa Furuta, MD, PhD (81-53-435-2850, furuta@hama-med.ac.jp), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The effect of FP-01 on the eradication rates of H. pylori infection by a triple 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 NCT00281047, which also lists 17 linked publications.
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 27 Jan 2006; AzTrials last refreshed its copy on 7 Nov 2026.
