ERADICATE Hp - Treating Helicobacter Pylori With RHB-105 (ERADICATE Hp)
|Dyspepsia Helicobacter Pylori Infection||Drug: RHB-105 Drug: Placebo||Phase 3|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
|Official Title:||A Randomized Placebo-Controlled Phase 3 Study to Assess the Safety and Efficacy of RHB-105 in the Treatment of Confirmed Helicobacter Pylori (H. Pylori) Infection in Non-investigated Dyspepsia Patients|
- The Occurrence of H. Pylori Eradication as Confirmed Via 13C UBT Testing [ Time Frame: 28-56 days after completion of treatment ]Modified intent-to-treat (mITT) population analyzed included all participants whok received at least 1 dose of study drug and underwent a 13C Urea Breath Test (UBT) at Visit 4. Participants with negative test results were to be considered treatment successes. Patients who tested positive for H. pylori infection, and those with indeterminate, not assessable, or missing results were to be considered treatment failures. The statistical hypothesis that the active treatment is superior to 70% was to be tested against the alternative hypothesis that the active treatment is statistically indistinguishable or less than 70% effective using a one-sample Z-test.
- H. Pylori Eradication [ Time Frame: 28-56 days after completion of SOC treatment ]The occurrence of H. pylori eradication in Placebo and Active Drug Eradication Failure Patients treated with Standard of Care (SOC) treatment

RHB-105 is an 'all-in-one' combination oral capsule consisting of 2 different antibiotics and a proton pump inhibitor combined in a single capsule.
The intended dose is RHB-105 (12.5 mg rifabutin, 250 mg amoxicillin, and 10 mg omeprazole capsules) 4 capsules every eight hours, equivalent to a total daily dose of:
Subjects will take study drug every 8 hours with food for 14 consecutive days.
Placebo Comparator: Placebo
Capsules that look like the RHB-105 product but contain no active ingredient.
Subjects will take 4 placebo capsules every 8 hours with food for 14 days.
This is a, randomized, double-blind, placebo-controlled study of RHB-105 in adult subjects complaining of epigastric discomfort that have been screened and found to be positive for H. pylori infection via 13C Urea Breath Test (UBT) and either fecal antigen test or CLO test.
Eligible subjects will be randomized in a ratio of 1:2 between placebo arm (n=30) and the active arm (RHB-105) (n=60). Subjects will receive study drug for 14 consecutive days. Eradication of H. pylori infection will be determined based on 13C UBT conducted between 28 to 56 days after completion of study drug therapy.
Subjects will be unblinded upon 13C UBT analysis. This will provide timely active therapy to all subjects enrolled in this study. Subjects in the placebo arm will be entitled to receive standard-of-care as prescribed by the treating physician following un-blinding.
Eradication failures (13C UBT-positive) in the active study drug arm will undergo upper endoscopy with sampling for culture and sensitivity testing (to rifabutin, amoxicillin, clarithromycin, and metronidazole). Culture and sensitivity directed therapy as prescribed by the treating physician will be offered to these subjects.
