Objectives. The aim of this study was to investigate and compare the eradication rate of Helicobacter pylori as the third-line triple therapy with rabeprazole (RPZ) + amoxicillin (AMPC) + levofloxacin (LVFX) and high-dose RPZ + AMPC. Methods. 51 patients who failed Japanese first-line (proton pump inhibitor (PPI) + AMPC + clarithromycin) and second-line (PPI + AMPC + metronidazole) eradication therapy were randomly assigned at a 1 : 1 ratio to one of the following third-line eradication groups: (1) RAL group: RPZ 10 mg (b.i.d.), AMPC 750 mg (b.i.d.), and LVFX 500 mg (o.d.) for 10 days; (2) RA group: RPZ 10 mg (q.i.d.) and AMPC 500 mg (q.i.d.) for 14 days. Patients who failed to respond to third-line eradication therapy received salvage therapy. Results. The rates of eradication success, based on intention to treat (ITT) analysis, were 45.8% in the RAL group and 40.7% in the RA group. The overall eradication rates were 73.9% in the RAL group and 64.0% in the RA group. There was no significant difference between the two groups. Conclusions. The third-line triple therapy with RPZ, AMPC, and LVFX was as effective as that with high-dose RPZ and AMPC.

Background/Aims: Fluoroquinolone-containing triple eradication therapy could be considered an alternative regimen for the second- line treatment of <i>Helicobacter pylori</i> infection. This study aimed to investigate the changes in the eradication efficacy of fluoroquinolone- containing triple therapy from 2003 to 2018 in Korea.Materials and Methods: Patients with a history of first-line eradication therapy failure were consecutively enrolled at Seoul National University Bundang Hospital from 2003 to 2018. All patients took moxifloxacin-containing triple therapy as the second-line eradication therapy. The treatment regimen comprised a three-drug combination comprising a proton pump inhibitor, amoxicillin, and moxifloxacin. Data on age, sex, endoscopic diagnosis, eradication results, compliance, and adverse outcomes were acquired and analyzed.Results: In total, 824 participants were enrolled during the study period, of whom, 46 were lost to follow-up. Finally, 778 participants were included in the per-protocol (PP) analysis, of whom, 72.1% received moxifloxacin-containing triple therapy for 14 days. The eradication rate of moxifloxacin-containing triple therapy was 72.1% (594/824) in the intention-to-treat analysis and 76.3% (594/778) in the PP analysis. A decline in eradication efficacy was observed, especially in the PP analysis (<i>P</i>=0.046). Diarrhea was the most commonly observed adverse event, accounting for 19.6% (41/209) of recorded adverse events.Conclusions: Moxifloxacin-containing triple therapy has shown suboptimal eradication efficacy as the second-line eradication therapy. In addition, there is a concern that eradication rate will decrease due to increase in antimicrobial resistance.

<b><i>Backgrounds/Aims:</i></b> Vonoprazan (VPZ) is the first clinically available potassium competitive acid blocker. This class of agents provides faster and more potent acid inhibition than proton pump inhibitors. Most strains of <i>Helicobacter pylori</i> are sensitive to amoxicillin. We hypothesized that dual therapy with VPZ and amoxicillin would provide the sufficient eradication rate for <i>H. pylori</i> infection. To evaluate this, we compared the eradication rate by the dual VPZ/amoxicillin therapy with that by the standard triple VPZ/amoxicillin/clarithromycin therapy. <b><i>Methods:</i></b> Non-inferiority of the eradication rate of <i>H. pylori</i> by the dual therapy with VPZ 20 mg twice daily (bid) and amoxicillin 500 mg 3 times daily (tid) for 1 week to that by the triple therapy with VPZ 20 mg bid, amoxicillin 750 mg bid and clarithromycin 200 mg bid for 1 week was retrospectively studied. Propensity score matching was performed to improve comparability between 2 regimen groups. Successful eradication was diagnosed using the [<sup>13</sup>C]-urea breath test at 1–2 months after the end of eradication therapy. <b><i>Results:</i></b> The intention-to-treat analysis demonstrated that the eradication rate by the dual therapy (92.9%; 95% CI 82.7–98.0%, 52/56) was not inferior to that of the triple therapy (91.9%; 95% CI 80.4–97.0%, 51/56; OR 1.275, 95% CI 0.324–5.017%, <i>p</i> = 0.728). There were no statistically significant differences in incidences of adverse events between 2 regimens. <b><i>Conclusion:</i></b> VPZ-based dual therapy (VPZ 20 mg bid and amoxicillin 500 mg tid for 1 week) provides an acceptable eradication rate of <i>H. pylori</i> infection without the need for second antimicrobial agents, such as clarithromycin.

Background: Helicobacter pylori eradication containing the potassium-competitive acid blocker, vonoprazan, achieves a higher eradication rate than therapy with proton pump inhibitors (PPIs). Because vonoprazan is mainly metabolized by CYP3A4/5, CYP genotype may affect the eradication rate. We investigated the influence of antibiotic susceptibility and CYP3A4/5 and CYP2C19 genotypes on the eradication rates. Methods: A total of 307 Japanese who were genotyped for CYP3A4 *1/*22, CYP3A5 *1/*3 and CYP2C19 *1/*2/*3/*17, and investigated for susceptibility to antimicrobial agents, received vonoprazan-containing regimens: (1) With amoxicillin and clarithromycin as the first-line treatment; (2) with amoxicillin and metronidazole as the second-line treatment; or (3) with amoxicillin and sitafloxacin as the third-line treatment. Results: The eradication rate was 84.5% (95% confidence interval [CI]: 78.9–89.1%) using first-line, 92.6% (95% CI: 82.1–97.9%) using second-line and 87.5% (95% CI: 73.1–95.8%) using third-line treatment. Infection with clarithromycin-resistant strains was a predictive factor for failed eradication (odds ratio: 5.788, 95% CI: 1.916–17.485, p = 0.002) in multivariate analysis. No significant differences were observed in the eradication rate of regimens among CYP3A4, CYP3A5 and CYP2C19 genotypes. Conclusions: Genotyping for CYP3A4 *1/*22, CYP3A5 *1/*3 and CYP2C19 *1/*2/*3/*17 before vonoprazan-containing eradication treatment may not be useful for predicting clinical outcomes.

Eradication of Helicobacter pylori (H. pylori) is an effective strategy for preventing various gastrointestinal diseases such as gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. However, the eradication success rate is decreasing because of a recent increase in drug-resistant strains of H. pylori. Here, we evaluated the success rate of eradication therapy with vonoprazan (VPZ), a new potassium-competitive acid blocker, against drug-resistant H. pylori. In total, 793 patients who received H. pylori eradication therapy were investigated retrospectively. All underwent esomeprazole (EPZ)-based triple therapy (n = 386) or VPZ-based triple therapy (n = 407) for first-, second- and third-line H. pylori eradication for 7 days. The overall success rates of first- and third-line H. pylori eradication were significantly higher for VPZ-based triple therapy (88.4% and 93.0%, respectively, per protocol (PP)) than for EPZ-based triple therapy (69.5% and 56.5%, respectively, PP). Moreover, the success rates of first- and third-line eradication of clarithromycin (CLR)- and sitafloxacin (STFX)-resistant H. pylori were significantly higher for VPZ-based triple therapy (72.0% and 91.7%, PP) than for EPZ-based triple therapy (38.5% and 20.0%, PP). In addition, patient age did not affect the eradication rate of VPZ-based first-line therapy, whereas the success rate of EPZ-based therapy was lower in patients under 65 years of age. Our results clearly demonstrated that VPZ-based therapy achieved a higher eradication rate even against CLR- and STFX-resistant H. pylori, and that patient age did not affect the eradication rate of VPZ-based therapy. These findings suggest that dual therapy using VPZ and amoxicillin may be sufficient for standard H. pylori eradication, and may thus also be beneficial for avoiding antibiotic misuse.

The eradication of Helicobacter pylori (H. pylori) may be difficult due to antibiotic resistance. Indeed, after one failure, a second-line therapy is needed and a bismuth containing quadruple therapy (BQT) with a three-in-one capsule formulation is becoming very popular. Therefore, we aimed to evaluate effectiveness and safety of BQT as a second-line therapy. We recruited consecutive patients with one therapy failure. For ten days patients received the three-in-one BQT Pylera® therapy, in combination with a proton-pump inhibitor (PPI), decided at the choice of the investigator, at full dose bid. The eradication rate was calculated by intention-to-treat (ITT) and per-protocol (PP)analyses and 95% confidence intervals (CI) were calculated. Seventy-three patients were recruited, 41 females and 32 males (mean age 53.0±13.1 years). Fifty-five patients failed triple therapy with amoxicillin and clarithromycin and the remaining 18 received sequential therapy. Seventy-two patients consumed at least 90% of the capsules, while only one did not complete the therapy due to adverse events (nausea and diarrhea). By ITT analysis, BQT was successful in 62 subjects (eradication rate 84.9%, 95%CI 76.7–93.1%). By PP analysis, the eradication rate was 86.1% (95%CI 78.1–94.1%).Adverse events were observed in 14 subjects (20.5%).In conclusion, our report confirmed that BQT is effective as an empiric second-line regimen.

BACKGROUND:Helicobacter pylorieradication rates achieved by standard seven-day triple therapies are decreasing in several countries, while a novel 10-day sequential regimen has achieved a very high success rate. A longer 10-day triple therapy, similar to the sequential regimen, was tested to see whether it could achieve a better infection cure rate.METHODS: Patients with nonulcer dyspepsia andH pyloriinfection were randomly assigned to one of the following three therapies: esomeprazole 20 mg, clarithromycin 500 mg and amoxycillin 1 g for seven days or 10 days, or a 10-day sequential regimen including esomeprazole 20 mg plus amoxycillin 1 g for five days and esomeprazole 20 mg, clarithromycin 500 mg and tinidazole 500 mg for the remaining five days. All drugs were given twice daily.H pylorieradication was checked four to six weeks after treatment by using a13C-urea breath test.RESULTS: Overall, 213 patients were enrolled.H pylorieradication was achieved in 75.7% and 77.9%, in 81.7% and 84.1%, and in 94.4% and 97.1% of patients following seven-day or 10-day triple therapy and the 10-day sequential regimen, at intention-to-treat and per protocol analyses, respectively. The eradication rate following the sequential regimen was higher than either seven-day (P=0.002) or 10-day triple therapy (P=0.02), while no significant difference emerged between the latter two regimens (P=0.6).CONCLUSIONS: The 10-day sequential regimen was significantly more effective than both triple regimens, while 10-day triple therapy failed to significantly increase theH pylorieradication rate achieved by the standard seven-day regimen.

Abstract Introduction and Methods Salvage chemotherapy followed by high-dose therapy and autologous stem cell transplantation (ASCT) is the standard of care for relapsing/refractory DLBCL. In the CORAL study, there was no difference between two randomized second line regimens (R-DHAP or R-ICE) and only half of the patients (pts) eventually underwent per protocol ASCT (Gisselbrecht et al, JCO 2010 & 2012). Because outcome data are limited in DLBCL pts failing second-line strategy, 145 pts included in the CORAL study who failed R-DHAP or R-ICE and could not proceed to scheduled ASCT were herein reviewed. Results Median age was 56y (range 20-67, 31% > 60y), M/F ratio 91/54, IPI 0-1 in 30%, 2-3 in 56%, and 4-5 in 14%. Third-line therapy consisted of ICE-type (19%), DHAP-type (19%), gemcitabine-containing (16%), CHOP-like (8%), dexaBEAM (8%), and miscellaneous (31%) regimens with or without rituximab according to centre policy. Overall response rate to third-line chemotherapy was 43%, with 21% complete response (CR), 8% CR unconfirmed (CRu), and 14% PR. CR/CRu and PR rates among pts treated with ICE-type, DHAP-type, gemcitabine-containing, or CHOP-like regimens were 23 and 23%, 35 and 8%, 9 and 4%, 25 and 25%, respectively. Among the 145 patients, 64 (44%) could eventually be transplanted (ASCT 56, allogeneic SCT 8). Median overall survival (OS), calculated from time of second failure until death, was 5.9 months (95% CI 4.6-7.5; min: 0.0-max: 68.8 months; median follow-up: 32.8 months) and was not influenced by the type of third-line regimen (p=.49). OS was statistically different (p<.0001) according to IPI at CORAL failure: IPI 0-2: 11.1 months (1-y OS 42.9%), IPI > 2: 3.7 months (1-y OS 7.7%, HR 3.021). OS in pts achieving CR/CRu, PR, or no response after third-line regimen was 63.6 m (1-y OS 72.1%, p<.0001), 12.8 m (1-y OS 53.5%, p=.04), and 4.4 months (1-y OS 9.2%), respectively. Median OS of pts who could eventually be transplanted was 11.1 months (1-y OS 41.6%), as compared to a median OS of 5.0 months in those who were not transplanted (1-y OS 19.2%) with a HR of 2.182 (1.41-3.38, p<.0001, Figure 1). Median OS of pts transplanted in CR after third-line regimen was not reached as compared to those in PR (11.8 months) or those with no response (4.4 months, p<.0001). There was no statistically-significant difference in median OS between ASCT and alloSCT, taking into account the low numbers. In multivariate Cox analysis, IPI at relapse (HR 2.409) and transplantation (HR 0.381) independently predicted for OS. Conclusions Outcome of DLBCL pts failing second-line R-DHAP or R-ICE is overall poor. However, response to third-line therapy occurs, and 44% of the pts can be further transplanted. Long-term disease control can be observed, especially in pts achieving CR after third-line. This approach (salvage chemotherapy aiming at achieving response followed by transplantation) should then be encouraged in these patients, although there is obviously an urgent need for new drugs improving salvage efficacy.

This randomized controlled study aimed to evaluate whether adding bismuth to the standard first-line triple therapy could improve the eradication rate of Helicobacter pylori. A total of 162 patients with Helicobacter pylori infection were randomly assigned to either the 7-day triple therapy group (RAK regimen: rabeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg bid; n=81) or the bismuth plus triple therapy group (n=81). In the RBAK group, bismuth subcitrate 360 mg twice daily was added to the RAK regimen. A follow-up endoscopy or urea breath test was performed at least 4 weeks after eradication to confirm the treatment efficacy. Comparable compliance and Helicobacter pylori eradication rates were observed in both groups in either intention-to-treat [RAK 72.8% (59/81) versus RBAK 77.8% (63/81); p=0.47] or per protocol analysis [RAK 74.7% (59/79) versus RBAK 81.8% (63/77); p=0.26]. Adverse effects were commonly reported (50.6% for both groups) although most of these did not cause cessation of treatment. The resistance rate was 27.2% for metronidazole and 12.3% for clarithromycin. Adding bismuth to the standard 7-day triple therapy did not substantially increase the eradication rate. Further study is needed clarifying whether extending the duration of RBAK regimen to 10–14 days can lead to a better result.
