Rifabutin-Containing Triple Therapy (RHB-105) for Eradication of Helicobacter pylori: Randomized ERADICATE Hp Trial.

ABSTRACT: Due to increasing resistance to commonly used antibiotics, the World Health Organization and Food and Drug Administration have advocated the development of new therapeutic regimens for Helicobacter pylori (H. pylori). This phase three, double-blind study (ERADICATE Hp) randomized (2:1) treatment-naïve adults with H. pylori infection and dyspepsia to RHB-105 (an all-in-one combination of omeprazole 40 mg, amoxicillin 1000 mg, and rifabutin 50 mg) or an identically-appearing placebo, both administered every 8 h for 14 days. The H. pylori eradication rate with RHB-105, using a modified intent-to-treat (mITT) population of subjects who received ?1 dose of study drug and had test-of-eradication performed 28-35 days post-completion of therapy, was compared (one-sample Z-test) to a literature-derived comparator rate of 70% and success rate with physician-selected standard-of-care given to placebo failures. The mITT H. pylori eradication rate (95% CI) with RHB-105 of 89.4% (82.0-96.8%) was greater than both the literature-derived comparator rate (P < 0.001) and the standard-of-care rate of 63.0% (44.8-81.1%) (P = 0.006). Adverse events with an incidence ?5% for RHB-105 were diarrhea (12.7%), headache (11.9%), chromaturia (9.3%), abdominal tenderness (6.8%), and dizziness (5.1%). No leukopenia was noted. RHB-105 (Talicia®) proved to be a safe and effective empiric therapy for H. pylori eradication.

Project description:Background:The efficacy and applicability of molecular testing to guide the selection of antibiotics in triple Helicobacter pylori (H. pylori) eradication regimens have not been reported. We tested a 7-day, genotypic resistance-guided triple H. pylori eradication therapy in a high-resistance setting. Methods:Consecutive dyspeptic patients with H. pylori infection were prospectively enrolled. Genotypic resistances to clarithromycin (23SrRNA mutations) and fluoroquinolones (gyrA mutations) were determined from gastric biopsy specimens using a commercially available molecular assay (GenoTypeâ HelicoDR). A tailored genotypic resistance-guided 7-day triple therapy comprised esomeprazole, amoxicillin, and either clarithromycin (wild-type 23SrRNA), levofloxacin (23SrRNA mutated/wild-type gyrA) or rifabutin (both 23SrRNA/gyrA mutated). H. pylori eradication was confirmed by 13C-urea breath test. Results:Of 148 subjects screened, 51 patients were enrolled (male/female: 27/24, mean age: 50.7±11.4 years, treatment-naïve/-experienced: 32/19). The molecular kit was easily implemented, allowing for rapid (within 24 h) and relatively inexpensive determination of H. pylori resistance (clarithromycin: 47.1%, fluoroquinolones: 15.7%, dual clarithromycin/fluoroquinolones: 7.8%). For patients who received clarithromycin-, levofloxacin- and rifabutin-containing triple therapy, the respective eradication rates were 24/27, 20/20, and 2/4 by intention-to-treat (ITT); and 24/24, 19/19 and 2/3 by per-protocol (PP) analysis. Overall eradication rates were 90.2% (95% confidence interval [CI] 77.8-96.3%) by ITT and 97.8% (95%CI 87-99.8%) by PP analysis, showing no significant difference between treatment-naïve and -experienced patients (ITT: 87.5% vs. 94.7%, P=0.64; PP: 96.4% vs. 100%, respectively, P=1.00). Conclusions:Regardless of prior treatment history, a genotypic resistance-guided 7-day triple therapy, based on a simple molecular assay, achieved a high H. pylori eradication rate.

Project description:Objective:To assess the effects and safety of berberine combined with triple therapy on Helicobacter pylori (H. pylori) eradication in adults. Methods:PubMed, MEDLINE, EMBASE, Cochrane Library, and Chinese databases including China National Knowledge Infrastructure (CNKI), Wanfang data, Chinese Technology Journal Full-text Database (VIP), and China biomedical literature database (CBM) were searched to obtain the eligible studies published up to October 10, 2017. The primary outcome was eradication rate of H. pylori. The secondary outcome was incidence of adverse effects. Data analysis was conducted by RevMan5.2 and Stata V.9.0 software. Trial sequential analysis (TSA) was performed to assess the risk of random error and the validity of conclusion with TSA program version 0.9 beta. Results:The meta-analysis results indicated berberine combined with triple therapy could improve the eradication rates of H. pylori (urea breath test subgroup: RR=1.18, 95%CI=(1.12,1.24), P < 0.00001, biopsy subgroup: RR=1.23, 95%CI=(1.13,1.34), P < 0.00001) and reduce the total occurrence of adverse effects (OR=0.59, 95%CI(0.46, 0.75), P < 0.0001) when compared with only using triple therapy. Besides, the incidence of nausea (OR=0.59, 95%CI(0.41, 0.86), P < 0.05) and diarrhea (OR=0.41, 95%CI(0.24, 0.71) was remarkably lower in experimental group while that of abdominal distention (OR=0.64, 95%CI(0.40,1.04), P > 0.05) and vomiting (OR=0.65, 95%CI(0.37, 1.15), P > 0.05) had no significant change. TSA of H. pylori eradication rates and adverse effects incidence illustrated that the cumulative value of Z-curve went across the conventional boundary value, trial sequential monitoring boundary for benefit, and required information size, suggesting the results were stable. Conclusion:Evidence from meta-analysis suggested that berberine combined with triple therapy can be an option for increasing H. pylori eradication rates and reducing overall therapy-related adverse effects incidence, particularly nausea and diarrhea, whereas more randomized controlled trials designed according to CONSORT statement are demanded to support the efficacy in further studies.
