1. Study identification
EU PAS Register NumberEUPAS3142
Official titleA Safety and Pharmacokinetic study in Real-life practice of Pylera® in France: The SAPHARY study
Study title acronymSAPHARY
Study typeOther: Clinical Pharmacokinetics
Brief description of the studyThe primary objective of the study is to verify the absence of accumulation of bismuth in subjects prescribed Pylera®. The study is a single-arm, open label trial in 200 presumed Helicobacter Pylori-positive subjects and is restricted to centers in France.
This study has an anticipated recruitment period of 24 months. Eligible subjects will stay in study for approximately 6 weeks.
Following identification of participating general practice and specialist study centers, subjects deemed eligible for study will be identified and may be enrolled. To assess eradication, subjects will complete a diagnostic H. pylori test (breath test, biopsy, or other test at the discretion of the Investigator) following a period of at least 28 days after the end of treatment.
Subjects will provide two blood samples for assessment of plasma and whole blood bismuth concentrations, with one sample provided prior to start of Pylera® treatment and one sample provided upon completion of the 10-day treatment with Pylera®. If accumulation of bismuth is detected (defined as whole blood bismuth concentration exceeding 50 μg/L), subjects will be contacted to immediately return to the laboratory to draw a third verification sample and will be referred for potential inclusion and follow-up in a separate intensive monitoring program. In case of a neurological adverse event indicative of bismuth encephalopathy blood samples will be as quickly processed as possible. A diagnostic H. Pylori test to assess H. Pylori eradication should be repeated on one single occasion at least 28 days post-treatment.

Effectiveness evaluation
Safety and pharmacokinetic study
Primary scope : Safety and pharmacokinetic study
12. Main objective(s)
What is the main objective of the study?
To verify the absence of accumulation of bismuth in subjects prescribed Pylera, a pharmacokinetic approach in a real-life setting
Are there primary outcomes?Yes
Post-treatment whole blood and plasma concentration of bismuth (metal) will be described after subtraction of the baseline value for each subject. Individual observed results will also be classified as « above » or « bellow » the threshold of 50 micrograms per liter for whole blood bismuth concentrations.
Are there secondary outcomes?Yes
The safety profile will be assessed in terms of overall adverse events, vitals signs, and concomitant medication usage over 10-days treatment period, as well as at the 4 weeks follow-up period after treatment.
The eradication rate of Pylera is defined as the proportion of negative test of diagnostic H. Pylori test conducted at least 28 day following the end of treatment with Pylera.
13. Study design
What is the design of the study?
Pharmacokinetic study
Non-randomised clinical trial
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Eligible subjects will stay in the study for approximately 6 weeks with 2 follow-up visits: the end of treatment visit performed after the 10-day treatment with Pylera, and the end of study visit performed 28 days post-treatment.
15. Data analysis plan
Please provide a brief summary of the analysis method
A detailed statistical analysis plan will be performed before database lock using SAS® software.
Descriptive statistics including mean, median, standard deviation, minimum, and maximum will be presented for continuous variables. For categorial variables, the number of subjects and percentage within each category will be presented.
Bismuth concentrations (Cobs, Cmin) will be described at baseline and at the end of treatment and bismuth accumulation value will be estimated. Proportion of subjects who experienced any/serious adverse events will be assessed, including 95% confidence interval (CI).
The eradication rate of Pylera will be calculated from proportion and 95% CI of subjects having negative test of diagnostic H. pylori test at the end of study.
An interim analysis of bismuth concentration is planned 18 months after Pylera market launch. No statistical comparisons will be performed.
