E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the rate of Helicobacter pylori (H. pylori) eradication following quadruple therapy with bismuth subcitrate potassium, metronidazole, and tetracycline hydrochloride, given with omeprazole in H. pylori infected subjects, who failed one course of omeprazole-amoxicillin-clarithromycin (OAC) eradication therapy |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate the effect of antibiotic resistance of H. pylori on the efficacy of treatment with PYLERA™.
2. To assess the safety and tolerability of this therapeutic regimen with respect to subject-reported and investigator-observed adverse events, and clinical laboratory abnormalities.
3. To compare eradication outcomes in subjects with presence/past history of peptic ulcers at baseline versus those without.
4. To assess compliance to treatment.
5. To identify potential treatment success drivers in OAC-refractory subjects, including age, in vitro resistance, type and number of treatments, and comorbidities.
6. To evaluate resource utilization associated with treatment failure from twelve months prior to baseline. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Men or non-pregnant, non-nursing women, 18 years of age and older.
2. Women of childbearing potential must use a medically acceptable birth control method for the duration of the study (i.e. from Screening) and for 30 days thereafter. Women who are not of childbearing potential will be defined as postmenopausal (no presence of menses for at least 12 months if > 50 years of age, or no presence of menses for 24 months if ≤ 50 years of age), surgically sterilized (tubal ligation for at least 6 months, ovariectomy or hysterectomy) or
diagnosed infertile.
3. Positive for H. pylori status using both 13C-urea breath test (UBT) and rapid urease test (RUT).
4. Documented eradication failure to one prior course of OAC treatment, one prior course of OAC treatment and one supplemental treatment, one prior course of OAC treatment and two supplemental treatments, or one prior course of OAC treatment and three supplemental treatments.
5. Presence of upper gastrointestinal symptoms.
6. Mental and legal ability to give written informed consent. |
|
E.4 | Principal exclusion criteria |
1. Previous use of bismuth, metronidazole and tetracycline combination therapy for H. pylori eradication.
2. Previous surgery of the upper gastrointestinal tract (except cholecystectomy).
3. Presence or history of clinically significant impairment of renal function, hepatic function, or liver disease.
4. Presence or history of severe or unstable cardiovascular, pulmonary or endocrine disease.
5. Presence or history of Zollinger Ellison Syndrome.
6. Any current or recent (within 1 month of screening) hematemesis, melena, or documented gastrointestinal bleeding or iron-deficiency anaemia of clinical significance.
7. Malignant disease of any kind except for successfully treated skin cancer (basal or squamous cell) during the previous 5 years.
8. Barrett’s esophagus or high-grade dysplasia.
9. Dysphagia or vomiting as major symptoms.
10. Drug, alcohol or medication abuse within the past year.
11. Continuous use of anti-ulcer drugs, including H2-receptor antagonists, sucralfate and prostaglandins during the 2 weeks preceding the 13C-UBT at screening.
12. Continuous use of PPI in the 2 weeks preceding the 13C-UBT at screening.
13. Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) except acetylsalicylic acid 100 mg or less daily.
14. Requirement for anticoagulants/platelet aggregation inhibitors except for cardiovascular disease prevention (for example acetyl-salicylic at a dose not exceeding 100 mg daily) and systemic glucocorticoids (because of association with ulcer disease).
15. Use of systemic antibiotics in the 30 days prior to screening
16. Regular use (> 3 times per week) of bismuth compounds in the 30 days prior to screening.
17. Presence of a contraindication or hypersensitivity to the use of any of the active ingredients or excipients contained within the provided study medications: Omeprazole: subjects with rare hereditary problems of galactose intolerance, Lapp Lactase deficiency, Glucose-Galactose malabsoption; Bismuth; Metronidazole: active neurological disorder, history of blood dyscrasia, uncorrected hypothyroidism, uncorrected hypoadrenalism, alcoholism, concomitant use of disulfiram or use of disulfiram within the previous two weeks (can cause psychotic reactions); Tetracycline; Maalox® Plus: subjects with rare hereditary problems of fructose intolerance.
18. Use of any experimental drug or experimental device within the 30 days prior to screening and throughout the entire study.
19. Known hypersensitivity to or previous adverse experience(s) with citric acid or any of the study medications.
20. Subject known to be positive for human immunodeficiency virus (HIV), hepatitis, or other diseases transmissible by blood or biopsy samples.
21. Any concern by the Investigator regarding the safe participation of the subject in the study or for any other reason the Investigator considers the subject inappropriate for participation in the study. |
