Abstract
BACKGROUND The frequency and risk factors for gastrointestinal bleed (GIB) in patients with heart failure with reduced ejection fraction (HFrEF) have not been extensively researched. OBJECTIVE We aim to assess the frequency of GIB in this subset of patients and identify potential risk factors for bleeding. This study will evaluate the frequency of commonly used antiplatelet and anticoagulation agents in the HFrEF population, as well as look at some of the endoscopic features of the GIB. METHODS A retrospective cohort analysis of 670 patients admitted between November 2021 to August 2023 to a single urban, tertiary teaching institution with acute HFrEF ICD-10 codes. Upper or lower GIB (hematemesis, coffee ground emesis, melena or hematochezia during admission) was identified on a manual chart review. Patients with GIB were defined as our cases. No GIB was defined as our controls. Sub analysis included comparing the use of anticoagulant and antiplatelet between the cohort. Independent t test assessed statistical differences in the case and control groups RESULTS: Out of the 670 patients, 134 (20%) were identified with GIB. The cases were older than the controls (median age 77 vs. 70 years) (p = 0.001), had a lower hemoglobin (9 g/dL vs. 12 g/dL) (p =<0.05), and had higher BNP levels (7,938 pg/ml vs. 6472 pg/ml) (IQR: 3,239, 23,701) (p =<0.01). Among the anticoagulant users, 64% of cases were on an anticoagulant compared to 42% of the controls (p<0.05). Among the antiplatelet users, 68% of the controls were on one or more antiplatelet agents, compared to 52% in the controls (p = 0.01). When combining AC and AP treatment, there was no statistical difference between cases and controls. Ninety-three (69%) patients from cases had cross-sectional imaging with only 23 (25%) showing abnormal findings which included diverticulosis, colitis, and GI masses. When comparing upper endoscopy findings, the presence of esophageal diseases (esophagitis and esophageal varices) and gastric/duodenal diseases (gastritis, gastric ulcer, duodenal ulcer and AVM) were significantly higher in cases compared to controls (p < 0.05). In addition to the colonoscopy findings, polyps and diverticulosis were more prevalent in the cases compared to the controls (p = 0.01). CONCLUSION Heart failure patients are at risk of developing GIB. Age and high BNP on admission are risk factors for GIB, the higher the BNP levels the higher risk of GIB. Anticoagulant and antiplatelet use are associated with a higher risk of bleeding. However, the addition of dual antiplatelet therapy or concurrent antiplatelet and anticoagulation does not increase the risk of GIB. Some of the most common upper endoscopy findings include esophagitis/gastritis and esophageal/gastric ulcer. In terms of colonoscopy, findings include colonic mass, diverticulosis and hemorrhoids.

Abstract
Background/Aims Acid-suppressive drugs, such as proton pump inhibitors (PPIs), are treatment options for functional dyspepsia (FD). However, the efficacy of potassium-competitive acid blockers (P-CABs) in treating FD has not yet been established. This prospective multicenter clinical trial-based study aimed to assess the efficacy and safety of tegoprazan as a P-CAB treatment in patients with FD. Methods FD was diagnosed using the Rome IV criteria. All patients received tegoprazan 50 mg once daily for 8 weeks. Dyspeptic symptoms were assessed using a dyspepsia symptom questionnaire (5-point Likert scale, Nepean Dyspepsia Index-Korean [NDI-K], and gastroesophageal reflux disease-health-related quality of life [GERD-HRQL]). The main outcome was satisfactory symptom relief rates at 8 weeks. Results In this study, from the initial screening of 209 patients, 173 were included in the per-protocol set analysis. Satisfactory symptom relief rates at 8 and 4 weeks were 86.7% and 74.6%, respectively. In addition, the NDI-K and GERD-HRQL scores significantly improved at 8 and 4 weeks compared with the baseline scores. The efficacy of tegoprazan was not influenced by the FD subtype or Helicobacter pylori status. In patients with overlapping FD and GERD, there was a greater improvement in the NDI-K and GERD-HRQL scores than in patients with FD symptoms only. No serious drug-related adverse events occurred during this study. Conclusion Tegoprazan (50 mg) administered once daily provided satisfactory symptom relief for FD.

Efficacy of Vonoprazan vs. Intravenous Proton Pump Inhibitor in Prevention of Re-Bleeding of High-Risk Peptic Ulcers: A Randomized Controlled Pilot Study. J Clin Med 2024; 13:3606. [PMID: 38930134 PMCID: PMC11204564 DOI: 10.3390/jcm13123606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 06/03/2024] [Accepted: 06/17/2024] [Indexed: 06/28/2024] Open
Abstract
Background: Proton pump inhibitor (PPI) therapy is well-established for its effectiveness in reducing re-bleeding in high-risk peptic ulcer patients following endoscopic hemostasis. Vonoprazan (VPZ) has demonstrated the capacity to achieve gastric pH levels exceeding 4, comparable to PPIs. This study aims to evaluate the comparative efficacy of intravenous PPI infusion versus VPZ in preventing re-bleeding after endoscopic hemostasis in patients with high-risk peptic ulcers. Methods: A randomized, double-blind, controlled, and double-dummy design was employed. Patients with peptic ulcer bleeding (Forrest class IA/IB or IIA/IIB) who underwent endoscopic hemostasis were randomly assigned to either the PPI group or the VPZ group. Re-bleeding rates at 3, 7, and 30 days, the number of blood transfusions required, length of hospitalization, and ulcer healing rate at 56 days were assessed. Results: A total of 44 eligible patients were enrolled, including 20 patients (PPI group, n = 11; VPZ group, n = 9) with high-risk peptic ulcers. The mean age was 66 years, with 70% being male. Re-bleeding within 72 h occurred in 9.1% of the PPI group versus 0% in the VPZ group (p = 1.000). There was no significant difference in re-bleeding rates within 7 days and 30 days (18.2% vs. 11.1%, p = 1.000). Additionally, the ulcer healing rate did not significantly differ between the groups (87.5% vs. 77.8%). Conclusions: This pilot study demonstrates comparable efficacy between oral vonoprazan and continuous PPI infusion in preventing recurrent bleeding events among high-risk peptic ulcer patients following successful endoscopic hemostasis.

[PMID: 38931920 PMCID: PMC11207335 DOI: 10.3390/pharmaceutics16060799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Revised: 06/10/2024] [Accepted: 06/11/2024] [Indexed: 06/28/2024] Open
Abstract
Zastaprazan (JP-1366), a novel potassium-competitive acid blocker, is a new drug for the treatment of erosive esophagitis. JP-1366 is highly metabolized in human, mouse, and dog hepatocytes but moderately metabolized in rat and monkey hepatocytes when estimated from the metabolic stability of this compound in hepatocyte suspension and when 18 phase I metabolites and 5 phase II metabolites [i.e., N-dearylation (M6), hydroxylation (M1, M19, M21), dihydroxylation (M7, M8, M14, M22), trihydroxylation (M13, M18), hydroxylation and reduction (M20), dihydroxylation and reduction (M9, M16), hydrolysis (M23), hydroxylation and glucuronidation (M11, M15), hydroxylation and sulfation (M17), dihydroxylation and sulfation (M10, M12), N-dearylation and hydroxylation (M3, M4), N-dearylation and dihydroxylation (M5), and N-dearylation and trihydroxylation (M2)] were identified from JP-1366 incubation with the hepatocytes from humans, mice, rats, dogs, and monkeys. Based on the cytochrome P450 (CYP) screening test and immune-inhibition analysis with CYP antibodies, CYP3A4 and CYP3A5 played major roles in the metabolism of JP-1366 to M1, M3, M4, M6, M8, M9, M13, M14, M16, M18, M19, M21, and M22. CYP1A2, 2C8, 2C9, 2C19, and 2D6 played minor roles in the metabolism of JP-1366. UDP-glucuronosyltransferase (UGT) 2B7 and UGT2B17 were responsible for the glucuronidation of M1 to M15. However, JP-1366 and active metabolite M1 were not substrates for drug transporters such as organic cation transporter (OCT) 1/2, organic anion transporter (OAT) 1/3, organic anion transporting polypeptide (OATP)1B1/1B3, multidrug and toxic compound extrusion (MATE)1/2K, P-glycoprotein (P-gp), and breast cancer-resistant protein (BCRP). Only M1 showed substrate specificity for P-gp. The findings indicated that drug-metabolizing enzymes, particularly CYP3A4/3A5, may have a significant role in determining the pharmacokinetics of zastaprazan while drug transporters may only have a small impact on the absorption, distribution, and excretion of this compound.

Abstract
Background: Fexuprazan (Fexuclue®; Daewoong Pharmaceutical Co., Ltd., Seoul, Korea) is a novel potassium-competitive acid blocker (P-CAB). This multi-center, randomized, double-blind, active-controlled, parallel-group, therapeutic confirmatory, phase III study was conducted to assess its efficacy and safety compared with esomeprazole (Nexium®; AstraZeneca, Gothenburg, Mölndal, Sweden) in Korean patients with erosive esophagitis (EE). Methods: This study evaluated patients diagnosed with EE at a total of 25 institutions in Korea between 13 December 2018 and 7 August 2019. After voluntarily submitting a written informed consent form, the patients were evaluated using a screening test and then randomized to either of the two treatment arms. The proportion of the patients who achieved the complete recovery of mucosal breaks at 4 and 8 weeks, the proportion of those who achieved the complete recovery of heartburn at 3 and 7 days and 8 weeks, and changes in the GERD-Health-Related Quality of Life Questionnaire (GERD-HRQL) scores at 4 and 8 weeks from baseline served as efficacy outcome measures. The incidence of treatment-emergent adverse events (TEAEs) and adverse drug reactions (ADRs) and the serum gastrin levels served as safety outcome measures. Results: The study population comprised a total of 231 patients (n = 231) with EE, including 152 men (65.80%) and 79 women (34.20%); their mean age was 54.37 ± 12.66 years old. There were no significant differences in the efficacy and safety outcome measures between the two treatment arms (p > 0.05). Conclusions: It can be concluded that the efficacy and safety of Fexuclue® are not inferior to those of esomeprazole in Korean patients with EE.

Abstract
Novel potassium-competitive acid blockers (P-CABs) have emerged as effective acid-suppressive drugs in recent years, replacing proton pump inhibitors (PPIs). We aim to compare the efficacy and safety of P-CABs versus PPIs in the treatment of peptic ulcers with or without Helicobacter pylori (H. pylori) infection. We searched in PubMed, Embase, WOS, Cochrane Library, ClinicalTrials.gov, CNKI, and Wanfang databases (all years up to January 2024). Efficacy and safety outcomes were evaluated using odds ratio (OR) and 95% confidence intervals (CI). The Surface Under the Cumulative Ranking (SUCRA) probabilities were used to rank each intervention. Among 14,056 studies screened, 56 studies involving 9792 participants were analyzed. Vonoprazan demonstrated the best efficacy in ulcer healing rate and H. pylori eradication rate (SUCRA = 86.4% and 90.7%, respectively). Keverprazan ranked second in ulcer healing rates (SUCRA = 76.0%) and was more effective in pain remission rates (SUCRA = 91.7%). The risk of adverse events was low for keverprazan (SUCRA = 11.8%) and tegoprazan (SUCRA = 12.9%), and moderate risk for vonoprazan (SUCRA = 44.3%) was demonstrated. Compared to lansoprazole, vonoprazan exhibited a higher risk of drug-related adverse events (OR: 2.15; 95% CI: 1.60-2.89) and serious adverse events (OR: 2.22; 95% CI: 1.11-4.42). Subgroup analysis on patients with H. pylori-positive peptic ulcers showed that vonoprazan was at the top of the SUCRA rankings, followed by keverprazan. Vonoprazan showed superior performance in peptic ulcers, especially for patients with H. pylori-positive peptic ulcers. However, the risk of adverse events associated with vonoprazan should be noted. Keverprazan has also shown good therapeutic outcomes and has performed better in terms of safety.

Abstract
BACKGROUND Tegoprazan is a potassium-competitive acid blocker that inhibits gastric acid and which may be used for eradicating Helicobacter pylori. This study focuses on the pharmacokinetic interaction and safety between tegoprazan and the combination of clarithromycin, amoxicillin and bismuth in healthy Chinese subjects. METHODS An open-label, three-period, single-center, multiple-dosage, single-sequence, phase I trial was conducted in 22 healthy subjects. In period 1, the subjects took tegoprazan 50 mg twice daily for 7 days, and in period 2 they were administered clarithromycin 500 mg, amoxicillin 1000 mg and bismuth potassium citrate 600 mg twice daily for 7 days (days 14-20). Tegoprazan, clarithromycin, amoxicillin and bismuth potassium citrate were then administered in combination for 7 days (days 21-27) in period 3. Blood samples were collected up to 12 h after the last dose of each period. Safety assessments were performed in each period. RESULTS The geometric mean ratios (GMRs) [90% confidence interval (CI)] of maximum plasma concentration at steady state (Cmax,ss) and area under the plasma concentration-time curve over the dosing interval (AUCτ) at steady state were 195.93% (175.52-218.71%) and 287.54% (263.28-314.04%) for tegoprazan and 423.23% (382.57-468.22%) and 385.61% (354.62-419.30%) for tegoprazan metabolite M1, respectively. The GMRs (90% CI) of Cmax,ss and AUCτ were 83.69% (77.44-90.45%) and 110.30% (102.74-118.41%) for clarithromycin, 126.25% (114.73-138.93%) and 146.94% (135.33-159.55%) for 14-hydroxyclarithromycin, 75.89% (69.73-82.60%) and 94.34% (87.94-101.20%) for amoxicillin, and 158.43% (125.43-200.11%) and 183.63% (156.42-215.58%) for bismuth, respectively. All reported adverse events were mild. The frequency of adverse events during the coadministration stage was not higher than that during the single- or triple-drug administration stages. CONCLUSION The plasma exposure of tegoprazan, M1, 14-hydroxyclarithromycin and bismuth was increased after the coadministration of tegoprazan, clarithromycin, amoxicillin and bismuth. The coadministration exhibited favorable safety and tolerability. CLINICAL TRIALS REGISTRATION CTR20230643.

Vonoprazan 10 mg or 20 mg vs. lansoprazole 15 mg as maintenance therapy in Asian patients with healed erosive esophagitis: A randomized controlled trial. Chin Med J (Engl) 2024; 137:962-971. [PMID: 38654422 PMCID: PMC11046018 DOI: 10.1097/cm9.0000000000003068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND Erosive esophagitis (EE) is a gastroesophageal reflux disease characterized by mucosal breaks in the esophagus. Proton pump inhibitors are widely used as maintenance therapy for EE, but many patients still relapse. In this trial, we evaluated the noninferiority of vonoprazan vs. lansoprazole as maintenance therapy in patients with healed EE. METHODS We performed a double-blind, double-dummy, multicenter, phase 3 clinical trial among non-Japanese Asian adults with endoscopically confirmed healed EE from April 2015 to February 2019. Patients from China, South Korea, and Malaysia were randomized to vonoprazan 10 mg or 20 mg once daily or lansoprazole 15 mg once daily for 24 weeks. The primary endpoint was endoscopically confirmed EE recurrence rate over 24 weeks with a noninferiority margin of 10% using a two-sided 95% confidence interval (CI). Treatment-emergent adverse events (TEAEs) were recorded. RESULTS Among 703 patients, EE recurrence was observed in 24/181 (13.3%) and 21/171 (12.3%) patients receiving vonoprazan 10 mg or 20 mg, respectively, and 47/184 (25.5%) patients receiving lansoprazole (differences: -12.3% [95% CI, -20.3% to -4.3%] and -13.3% [95% CI, -21.3% to -5.3%], respectively), meeting the primary endpoint of noninferiority to lansoprazole in preventing EE recurrence at 24 weeks. Evidence of superiority (upper bound of 95% CI <0%) was also observed. At 12 weeks, endoscopically confirmed EE recurrence was observed in 5/18, 2/20, and 7/20 of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. TEAEs were experienced by 66.8% (157/235), 69.0% (156/226), and 65.3% (158/242) of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. The most common TEAE was upper respiratory tract infection in 12.8% (30/235) and 12.8% (29/226) patients in vonoprazan 10 mg and 20 mg groups, respectively and 8.7% (21/242) patients in lansoprazole group. CONCLUSION Vonoprazan maintenance therapy was well-tolerated and noninferior to lansoprazole for preventing EE recurrence in Asian patients with healed EE.

Comparison of vonoprazan dual therapy, quadruple therapy and standard quadruple therapy for Helicobacter pylori infection in Hainan: a single-center, open-label, non-inferiority, randomized controlled trial. BMC Gastroenterol 2024; 24:131. [PMID: 38609893 PMCID: PMC11010374 DOI: 10.1186/s12876-024-03225-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 04/09/2024] [Indexed: 04/14/2024] Open
Abstract
OBJECTIVE To compare the potential efficacy and safety of dual therapy and quadruple therapy with vonoprazan (VPZ) as well as the standard quadruple therapy of proton pump inhibitor (PPI) for the eradication of Helicobacter pylori (Hp) infection in Hainan province. METHODS A single-centre, non-blinded, non-inferiority randomized controlled trial was conducted at the outpatient department of gastroenterology at the Second Affiliated Hospital of Hainan Medical University from June 2022 to February 2023. 135 patients aged 18-75 years with Hp infection were enrolled and randomized into three different groups (group V1: VPZ 20 mg twice a day and amoxicillin 1.0 g three times a day for 14 days V2: vonoprazan 20 mg, amoxicillin capsules 1.0 g, furazolidone 0.1 g and bismuth potassiulm citrate 240 mg, twice daily for 14 days;; group V3: ilaprazole 5 mg, Amoxicillin 1.0 g, Furazolidone 100 mg, bismuth potassiulm citrate 240 mg, twice a day for 14 days). Four weeks after the end of treatment, Hp eradication was confirmed by rechecking 13C-urea breath test (UBT). RESULTS The eradication efficacy of V1 and V3 was non-inferior to that of V2, which is consistent with the results obtained from the Kruskal-Wallis H test. The eradication rate by intentional analysis was 84.4% (38/45, 95%CI 73.4%-95.5%, P>0.05) for all the three groups. If analyzed by per-protocol, the eradication rates were 88.4% (38/43, 95%CI 78.4%-98.4%), 92.7% (38/41, 95%CI 84.4%-101.0%),88.4% (38/43,95%CI 78.4%-98.4%) in groups V1, V2 and V3, respectively, which did not show a significant difference (P > 0.05). The incidence of adverse effects was significantly lower in VPZ dual therapy compared to the other two treatment regimens (P < 0.05). VPZ dual therapy or quadruple therapy was also relatively less costly than standard quadruple therapy. CONCLUSION VPZ dual therapy and quadruple therapy shows promise of not being worse than the standard quadruple therapy by a clinically relevant margin. More studies might be needed to definitively determine if the new therapy is equally effective or even superior.

Abstract
OBJECTIVE To investigate the efficacy and safety of vonoprazan based bismuth-containing quadruple therapy (VBCQ) in eradicating Helicobacter pylori (Hp). MATERIALS AND METHODS The VBCQ and the proton pump inhibitor-based bismuth-containing quadruple regimen (PBCQ) were compared by retrieving relevant studies in Pubmed, Embase, Cochrane Library, CNKI, and Wanfang data. Combined analysis was performed with risk ratio (RR) and 95% CI as effect values. RESULTS A total of 10 studies were enrolled, including 7 randomized controlled trials and 3 cohort studies. In intention-to-treat analysis, the eradication rate of VBCQ (89.24%, 1103/1236) was significantly higher than that of PBCQ (84.03%, 1021/1215), with RR = 1.06 (95% CI: 1.03~1.10). In per-protocol analysis, the eradication rates of VBCQ and PBCQ were 92.94% (895/963) and 87.82% (829/944), respectively, with a significant difference (RR = 1.06, 95% CI: 1.03~1.09). Subgroup analysis of study design types shared similar results. VBCQ and PBCQ showed an incidence of adverse reactions of 37.30% (304/815) and 34.94% (282/807), respectively. Significant differences were not found between the two groups (RR = 1.07, 95% CI: 0.96-1.19), nor in subgroup analysis. The good compliance rates in VBCQ and PBCQ groups were 94.32% (216/229) and 95.13% (215/226), respectively, with no significant difference (RR = 0.99, 95% CI: 0.95~1.04). CONCLUSION VBCQ has a higher eradication rate on Hp than PBCQ, while its adverse reactions and compliance are similar to PBCQ. However, we conservatively believe that in Hp eradication, the VBCQ is not inferior to PBCQ because of the small absolute difference.

Abstract
BACKGROUND & AIMS High-dose proton pump inhibitor (PPI) therapy has been recommended to prevent rebleeding of high-risk peptic ulcer (PU) after hemostasis. Vonoprazan has been proven to be noninferior to PPIs in various acid-related diseases. This study aimed to compare the efficacy of vonoprazan vs PPI for preventing high-risk PU rebleeding after hemostasis. METHODS A multicenter, randomized, noninferiority study was conducted in 6 centers. Pre-endoscopic and endoscopic therapy were performed according to standard protocol. After successful hemostasis, patients with high-risk PU bleeding (Forrest class Ia/Ib, IIa/IIb) were randomized into 1:1 to receive vonoprazan (20 mg twice a day for 3 days, then 20 mg once a day for 28 days) or high-dose PPI (pantoprazole intravenous infusion 8 mg/h for 3 days, then omeprazole 20 mg twice a day for 28 days). The primary outcome was a 30-day rebleeding rate. Secondary outcomes included 3- and 7-day rebleeding rate, all-cause and bleeding-related mortality, rate of rescue therapy, blood transfusion, length of hospital stay, and safety. RESULTS Of 194 patients, baseline characteristics, severity of bleeding, and stage of ulcers were comparable between the 2 groups. The 30-day rebleeding rates in vonoprazan and PPI groups were 7.1% (7 of 98) and 10.4% (10 of 96), respectively; noninferiority (within 10% margin) of vonoprazan to PPI was confirmed (%risk difference, -3.3; 95% confidence interval, -11.2 to 4.7; P < .001). The 3-day and 7-day rebleeding rates in the vonoprazan group remained noninferior to PPI (P < .001 by Farrington and Manning test). All secondary outcomes were also comparable between the 2 groups. CONCLUSION In patients with high-risk PU bleeding, the efficacy of vonoprazan in preventing 30-day rebleeding was noninferior to intravenous PPI. (ClinicalTrials.gov, Number: NCT05005910).

Abstract
BACKGROUND AND AIM Fexuprazan is a novel potassium-competitive acid blocker (P-CAB). This study aimed to explore the noninferior efficacy and safety of fexuprazan to esomeprazole in treating erosive esophagitis (EE). METHODS This was a phase III, randomized, double-blind multicenter study. Patients with endoscopically confirmed EE were randomized to receive fexuprazan 40 mg or esomeprazole 40 mg once a daily for 4-8 weeks. The healing rates of EE, symptom response, GERD-health-related quality life (GERD-HRQL), and treatment-emergent adverse events (TEAEs) were compared between fexuprazan group and esomeprazole group. RESULTS A total of 332 subjects were included in full analysis set (FAS) and 311 in per-protocol set (PPS). The healing rates of fexuprazan and esomeprazole groups at 8 weeks were 88.5% (146/165) and 89.0% (145/163), respectively, in FAS and 97.3% (145/149) and 97.9% (143/146), respectively, in PPS. Noninferiority of fexuprazan compared with esomeprazole according to EE healing rates at 8 weeks was demonstrated in both FAS and PPS analysis. No significant difference was found between groups in EE healing rates at 4 weeks, symptom responses, and changes of GERD-HRQL. The incidence of drug-related AEs was 19.4% (32/165) in fexuprazan arm and 19.6% (32/163) in esomeprazole arm. CONCLUSION This study demonstrated noninferior efficacy of fexuprazan to esomeprazole in treating EE. The incidence of TEAEs was similar between fexuprazan and esomeprazole. Trial registration number NCT05813561.

Abstract
BACKGROUND This study aimed to investigate the efficacy of bismuth added to a 2-week triple therapy consisting of tegoprazan (TPZ), amoxicillin, and clarithromycin for first-line Helicobacter pylori eradication. RESEARCH DESIGN AND METHODS We reviewed the retrospective data of patients who received a 2-week TPZ-based triple therapy with or without 300 mg bismuth twice daily. The primary endpoint was the H. pylori eradication rate of adding bismuth to the TPZ-based triple regimen (TAC-B group), compared to no bismuth added (TAC group). RESULTS In total, 306 and 256 patients were included in the intention-to-treat (ITT) and per-protocol (PP) analyses, respectively. The eradication success rates were significantly higher in the TAC-B group than in the TAC group (ITT, 82.9% vs. 71.8%, p = 0.029; PP, 95.8% vs. 87.5%, p = 0.027, respectively). The adherence rate to the eradication regimen was 100% in the TAC-B group and 97.0% in the TAC group. The adverse drug event rate in the TAC-B group was comparable to that in the TAC group (29.2% vs. 27.3%, p = 0.742). No use of bismuth was significantly associated with eradication failure (p = 0.038). CONCLUSIONS The bismuth add-on increased the first-line H. pylori eradication rate of 2-week TPZ-based triple therapy. CLINICAL TRIAL REGISTRATION www.clinicaltrials.gov identifier is NCT05453994.

Kanu JE, Soldera J. Treatment of Helicobacter pylori with potassium competitive acid blockers: A systematic review and meta-analysis. World J Gastroenterol 2024; 30:1213-1223. [PMID: 38577188 PMCID: PMC10989498 DOI: 10.3748/wjg.v30.i9.1213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 12/28/2023] [Accepted: 02/05/2024] [Indexed: 03/06/2024] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) infects over half the global population, causing gastrointestinal diseases like dyspepsia, gastritis, duodenitis, peptic ulcers, G-MALT lymphoma, and gastric adenocarcinoma. Eradicating H. pylori is crucial for treating and preventing these conditions. While conventional proton pump inhibitor (PPI)-based triple therapy is effective, there's growing interest in longer acid suppression therapies. Potassium competitive acid blocker (P-CAB) triple and dual therapy are new regimens for H. pylori eradication. Initially used in Asian populations, vonoprazan (VPZ) has been recently Food and Drug Administration-approved for H. pylori eradication. AIM To assess the efficacy of regimens containing P-CABs in eradicating H. pylori infection. METHODS This study, following PRISMA 2020 guidelines, conducted a systematic review and meta-analysis by searching MEDLINE and Scopus libraries for randomized clinical trials (RCTs) or observational studies with the following command: [("Helicobacter pylori" OR "H pylori") AND ("Treatment" OR "Therapy" OR "Eradication") AND ("Vonaprazan" OR "Potassium-Competitive Acid Blocker" OR "P-CAB" OR "PCAB" OR "Revaprazan" OR "Linaprazan" OR "Soraprazan" OR "Tegoprazan")]. Studies comparing the efficacy of P-CABs-based treatment to classical PPIs in eradicating H. pylori were included. Exclusion criteria included case reports, case series, unpublished trials, or conference abstracts. Data variables encompassed age, diagnosis method, sample sizes, study duration, intervention and control, and H. pylori eradication method were gathered by two independent reviewers. Meta-analysis was performed in R software, and forest plots were generated. RESULTS A total of 256 references were initially retrieved through the search command. Ultimately, fifteen studies (7 RCTs, 7 retrospective observational studies, and 1 comparative unique study) were included, comparing P-CAB triple therapy to PPI triple therapy. The intention-to-treat analysis involved 8049 patients, with 4471 in the P-CAB intervention group and 3578 in the PPI control group across these studies. The analysis revealed a significant difference in H. pylori eradication between VPZ triple therapy and PPI triple therapy in both RCTs and observational studies [risk ratio (RR) = 1.17, 95% confidence interval (CI): 1.11-1.22, P < 0.0001] and (RR = 1.13, 95%CI: 1.09-1.17, P < 0.0001], respectively. However, no significant difference was found between tegoprazan (TPZ) triple therapy and PPI triple therapy in both RCTs and observational studies (RR = 1.04, 95%CI: 0.93-1.16, P = 0.5) and (RR = 1.03, 95%CI: 0.97-1.10, P = 0.3), respectively. CONCLUSION VPZ-based triple therapy outperformed conventional PPI-based triple therapy in eradicating H. pylori, positioning it as a highly effective first-line regimen. Additionally, TPZ-based triple therapy was non-inferior to classical PPI triple therapy.

A systematic review with meta-analysis: Efficacy and safety of potassium-competitive acid blocker compared with proton pump inhibitor in the maintenance of healed erosive esophagitis. JGH Open 2024; 8:e13053. [PMID: 38523708 PMCID: PMC10958938 DOI: 10.1002/jgh3.13053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 02/18/2024] [Accepted: 02/27/2024] [Indexed: 03/26/2024]
Abstract
Introduction Proton pump inhibitor (PPI) is the mainstay therapy for the maintenance of healed erosive esophagitis (EE). It is unknown whether potassium-competitive acid blockers (PCABs) are more efficacious and safer than PPIs. Methods Only randomized controlled trials (RCTs) comparing PCABs to PPIs in the maintenance of healing rates of endoscopically proven healed EE and indexed in MEDLINE, EMBASE, and CENTRAL until 3 February 2024, were included. A fixed-effects model meta-analysis was performed to pool primary efficacy outcome (maintenance of healing rates at week 24) and safety data (any treatment-emergent adverse event or TEAE). The risk of bias was assessed using Cochrane's Risk of Bias 2 (RoB2) tool. Results Four RCTs with a total of 2554 patients were eligible for inclusion. All trials were of low risk of bias. Compared to lansoprazole 15 mg, the maintenance rates of healed EE at week 24 were significantly higher with vonoprazan 10 mg (RR 1.13; 95% CI 1.07-1.19) and vonoprazan 20 mg (RR 1.15; 95% CI 1.10-1.21). Likewise, compared to lansoprazole 15 mg, any TEAEs were significantly greater with vonoprazan 20 mg (RR 1.10; 95% CI 1.01-1.20) but not vonoprazan 10 mg. Conclusion Vonoprazan 10 and 20 mg were superior to lansoprazole 15 mg in the maintenance of the healing of EE. Any TEAEs were greater with vonoprazan 20 mg.

Abstract
BACKGROUND Low-dose aspirin (LDA) administration is associated with an elevated risk of recurring peptic ulcer (PU) and gastrointestinal (GI) hemorrhage. AIMS This systematic review and Bayesian network meta-analysis aimed to comprehensively assess the effectiveness of diverse medications in preventing the recurrence of PU and GI hemorrhage in patients with a history of PU receiving long-term LDA therapy. METHODS This systematic review and network meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and was registered on PROSPERO (CRD42023406550). We searched relevant studies in main databases from inception to March 2023. All statistical analyses were performed using R (version 4.1.3), with the "Gemtc" (version 1.0-1) package. The pooled risk ratio (RR), corresponding 95% credible interval (95% CrI), and the surface under the cumulative ranking curve (SUCRA) were calculated. RESULTS 11 Randomized clinical trials (RCTs) were included. The analysis underscored pantoprazole was the most efficacious for reducing the risk of PU recurrence (RR [95% CrI] = 0.02 [0, 0.28]; SUCRA: 90.76%), followed by vonoprazan (RR [95% CrI] = 0.03 [0, 0.19]; SUCRA: 86.47%), comparing with the placebo group. Pantoprazole also performed well in preventing GI hemorrhage (RR [95% CrI] = 0.01[0, 0.42]; SUCRA: 87.12%) compared with Teprenone. CONCLUSIONS For patients with a history of PU receiving LDA, pantoprazole and vonoprazan might be the optimal choices to prevent PU recurrence and GI hemorrhage.

Abstract
Helicobacter pylori is the most common chronic bacterial infection worldwide and the most significant risk factor for gastric cancer, which remains a leading cause of cancer-related death globally. H pylori and gastric cancer continue to disproportionately impact racial and ethnic minority and immigrant groups in the United States. The approach to H pylori case-finding thus far has relied on opportunistic testing based on symptoms or high-risk indicators, such as racial or ethnic background and family history. However, this approach misses a substantial proportion of individuals infected with H pylori who remain at risk for gastric cancer because most infections remain clinically silent. Moreover, individuals with chronic H pylori infection are at risk for gastric preneoplastic lesions, which are also asymptomatic and only reliably diagnosed using endoscopy and biopsy. Thus, to make a significant impact in gastric cancer prevention, a systematic approach is needed to better identify individuals at highest risk of both H pylori infection and its complications, including gastric preneoplasia and cancer. The approach to H pylori eradication must also be optimized given sharply decreasing rates of successful eradication with commonly used therapies and increasing antimicrobial resistance. With growing acceptance that H pylori should be managed as an infectious disease and the increasing availability of susceptibility testing, we now have the momentum to abandon empirical therapies demonstrated to have inadequate eradication rates. Molecular-based susceptibility profiling facilitates selection of a personalized eradication regimen without necessitating an invasive procedure. An improved approach to H pylori eradication coupled with population-level programs for screening and treatment could be an effective and efficient strategy to prevent gastric cancer, especially in minority and potentially marginalized populations that bear the heaviest burden of H pylori infection and its complications.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is very prevalent in the general population, with a broad spectrum of clinical manifestations, requiring accurate diagnosis and treatment. AIM The aim of this expert review is to establish good clinical practice recommendations for the diagnosis and personalized treatment of GERD. METHODS The good clinical practice recommendations were produced by a group of experts in GERD, members of the Asociación Mexicana de Gastroenterología (AMG), after carrying out an extensive review of the published literature and discussing each recommendation at a face-to-face meeting. This document does not aim to be a clinical practice guideline with the methodology such a document requires. RESULTS Fifteen experts on GERD formulated 27 good clinical practice recommendations for recognizing the symptoms and complications of GERD, the rational use of diagnostic tests and medical treatment, the identification and management of refractory GERD, the overlap with functional disorders, endoscopic and surgical treatment, and GERD in the pregnant woman, older adult, and the obese patient. CONCLUSIONS An accurate diagnosis of GERD is currently possible, enabling the prescription of a personalized treatment in patients with this condition. The goal of the good clinical practice recommendations by the group of experts from the AMG presented in this document is to aid both the general practitioner and specialist in the process of accurate diagnosis and treatment, in the patient with GERD.

Efficacy comparison of 7- and 14-day P-CAB based bismuth-containing quadruple regimen with PPI based bismuth-containing quadruple regimen for Helicobacter pylori infection: rationale and design of an open-label, multicenter, randomized controlled trial. BMC Gastroenterol 2023; 23:453. [PMID: 38129806 PMCID: PMC10734161 DOI: 10.1186/s12876-023-03100-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 12/14/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Owing to its strong acid inhibition, potassium-competitive acid blocker (P-CAB) based regimens for Helicobacter pylori (H. pylori) eradication are expected to offer clinical advantages over proton pump inhibitor (PPI) based regimens. This study aims to compare the efficacy and adverse effects of a 7-day and a 14-day P-CAB-based bismuth-containing quadruple regimen (PC-BMT) with those of a 14-day PPI-based bismuth-containing quadruple regimen (P-BMT) in patients with high clarithromycin resistance. METHODS This randomized multicenter controlled clinical trial will be performed at five teaching hospitals in Korea. Patients with H. pylori infection who are naive to treatment will be randomized into one of three regimens: 7-day or 14-day PC-BMT (tegoprazan 50 mg BID, bismuth subcitrate 300 mg QID, metronidazole 500 mg TID, and tetracycline 500 mg QID) or 14-day P-BMT. The eradication rate, treatment-related adverse events, and drug compliance will be evaluated and compared among the three groups. Antibiotic resistance testing by culture will be conducted during the trial, and these data will be used to interpret the results. A total of 366 patients will be randomized to receive 7-day PC-BMT (n = 122), 14-day PC-BMT (n = 122), or 14-day P-BMT (n = 122). The H. pylori eradication rates in the PC-BMT and P-BMT groups will be compared using intention-to-treat and per-protocol analyses. DISCUSSION This study will demonstrate that the 7-day or 14-day PC-BMT is well tolerated and achieve similar eradication rates to those of 14-day P-BMT. Additionally, the 7-day PC-BMT will show fewer treatment-related adverse effects and higher drug compliance, owing to its reduced treatment duration.

Pilot studies of vonoprazan-containing Helicobacter pylori eradication therapy suggest Thailand may be more similar to the US than Japan. Helicobacter 2023; 28:e13019. [PMID: 37723133 DOI: 10.1111/hel.13019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 08/01/2023] [Accepted: 08/27/2023] [Indexed: 09/20/2023]
Abstract
BACKGROUND Vonoprazan-containing Helicobacter pylori eradication is reliably effective in Japan. Its effectiveness in other countries remains unclear. Here, we examined vonoprazan-H. pylori therapies in Thailand. MATERIALS AND METHODS This was pilot study of four different vonoprazan containing therapies. Subjects were randomized to: 14-day dual therapy (500 mg amoxicillin q.i.d. plus 20 mg vonoprazan b.i.d.), 14-day triple therapy (amoxicillin 1 g b.i.d., slow release clarithromycin-MR, 1 g daily plus vonoprazan 20 mg b.i.d.), 7-day high-dose vonoprazan triple therapy (amoxicillin 1 g b.i.d., clarithromycin-MR 1 g daily and 60 mg vonoprazan once daily), and 14-day vonoprazan triple therapy plus bismuth (amoxicillin 1 g b.i.d., clarithromycin-MR 1 g daily, vonoprazan 20 mg b.i.d., and bismuth subsalicylate 1048 mg b.i.d.). Eradication was confirmed 4 weeks after therapy. Antimicrobial susceptibility and CYP3A4/5 genotyping were performed. RESULTS One hundred H. pylori-infected patients (mean age 54.3 ± 13 years, 51% men) were randomized. All were CYP3A4 extensive metabolizers. Cure rates with both 14-day vonoprazan dual therapy and 14-day triple therapy were low: 66.7%; 95% CI = 43-85% (14/21), and 59.3%; 95% CI = 39-78%) (16/27), respectively. In contrast, 7-day high-dose vonoprazan triple therapy and 14-day vonoprazan triple plus bismuth proved effective 92.3%; 95% CI = 75%-99% (24/26) and 96.2%; 95% CI = 80%-100% (25/26), respectively. CONCLUSION Both 14-day vonoprazan dual and triple therapy were ineffective for H. pylori eradication in Thailand. Higher dosage of vonoprazan, and/or the addition of bismuth may be required to achieve high H. pylori eradication rates. High-dose vonoprazan triple therapy and vonoprazan triple therapy adding bismuth might be used as first-line treatments in some regions with high efficacy irrespective of CYP3A4/5 genotype and clarithromycin resistance.

[PMID: 36728978 PMCID: PMC9897767 DOI: 10.1080/13880209.2023.2173253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 11/16/2022] [Accepted: 01/20/2023] [Indexed: 06/18/2023]
Abstract
CONTEXT Poziotinib and vonoprazan are two drugs mainly metabolized by CYP3A4. However, the drug-drug interaction between them is unknown. OBJECTIVE To study the interaction mechanism and pharmacokinetics of poziotinib on vonoprazan. MATERIALS AND METHODS In vitro experiments were performed with rat liver microsomes (RLMs) and the contents of vonoprazan and its metabolite were then determined with UPLC-MS/MS after incubation of RLMs with vonoprazan and gradient concentrations of poziotinib. For the in vivo experiment, rats in the poziotinib treated group were given 5 mg/kg poziotinib by gavage once daily for 7 days, and the control group was only given 0.5% CMC-Na. On Day 8, tail venous blood was collected at different time points after the gavage administration of 10 mg/kg vonoprazan, and used for the quantification of vonoprazan and its metabolite. DAS and SPSS software were used for the pharmacokinetic and statistical analyses. RESULTS In vitro experimental data indicated that poziotinib inhibited the metabolism of vonoprazan (IC50 = 10.6 μM) in a mixed model of noncompetitive and uncompetitive inhibition. The inhibitory constant Ki was 0.574 μM and the binding constant αKi was 2.77 μM. In vivo experiments revealed that the AUC(0-T) (15.05 vs. 90.95 μg/mL·h) and AUC(0-∞) (15.05 vs. 91.99 μg/mL·h) of vonoprazan increased significantly with poziotinib pretreatment. The MRT(0-∞) of vonoprazan increased from 2.29 to 5.51 h, while the CLz/F value decreased from 162.67 to 25.84 L/kg·h after pretreatment with poziotinib. CONCLUSIONS Poziotinib could significantly inhibit the metabolism of vonoprazan and more care may be taken when co-administered in the clinic.

Abstract
Background/Aims Fexuprazan is a novel potassium-competitive acid blocker that could be of benefit to patients with gastric mucosal injury. The aim of this study was to assess the 2-week efficacy and safety of fexuprazan in patients with acute or chronic gastritis. Methods In this study, 327 patients with acute or chronic gastritis who had one or more gastric erosions on endoscopy and subjective symptoms were randomized into three groups receiving fexuprazan 20 mg once a day (q.d.), fexuprazan 10 mg twice a day (b.i.d.), or placebo for 2 weeks. The posttreatment assessments were the primary endpoint (erosion improvement rate), secondary endpoints (cure rates of erosion and edema and improvement rates of redness, hemorrhage, and subjective symptoms), and drug-related adverse events. Results Among the patients, 57.8% (59/102), 65.7% (67/102), and 40.6% (39/96) showed erosion improvement 2 weeks after receiving fexuprazan 20 mg q.d., fexuprazan 10 mg b.i.d., and placebo, respectively. Both fexuprazan 20 mg q.d. and 10 mg b.i.d. showed superior efficacy to the placebo (p=0.017 and p<0.001, respectively). Likewise, both fexuprazan 20 mg q.d. and 10 mg b.i.d. also showed higher erosion healing rates than the placebo (p=0.033 and p=0.010, respectively). No difference was noted in the edema healing rate and the improvement rates for redness, hemorrhage, and subjective symptoms between the fexuprazan and placebo groups. No significant difference was noted in the incidence of adverse drug reactions. Conclusions Fexuprazan 20 mg q.d. and 10 mg b.i.d. for 2 weeks showed therapeutic efficacy superior to that of placebo in patients with acute or chronic gastritis (ClinicalTrials.gov identifier NCT04341454).

Efficacy of Vonoprazan vs. Pantoprazole or Non-acid Suppression in Prevention of Post-variceal Ligation Ulcer Bleeding in Portal Hypertension: A Multi-arm Randomized Controlled Trial. J Clin Exp Hepatol 2023; 13:962-971. [PMID: 37975046 PMCID: PMC10643493 DOI: 10.1016/j.jceh.2023.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Accepted: 05/15/2023] [Indexed: 11/19/2023] Open
Abstract
Background Up-to-date data about the role of acid suppression therapy e.g. proton-pump inhibitors; to reduce post-endoscopic variceal ligation (EVL) ulcer-bleeding are conflicting. Vonoprazan; a recently introduced potassium-competitor acid blocker, has not been studied to prevent post-EVL ulcer/bleeding. The aim was to evaluate the efficacy of vonoprazan vs. pantoprazole or non-acid suppression to prevent post-EVL ulcer/bleeding in portal hypertension patients. Material and methods We enrolled 275 portal hypertension patients undergoing EVL in a three-arm randomized, single-blind, controlled study. A clinico-laboratory baseline evaluation was performed. Following EVL, patients were randomly and equally assigned to receive vonoprazan 20mg once daily, pantoprazole 40 mg once daily, or no acid suppression therapy. Post-EVL ulcer bleeding, ulcer dimensions, odynophagia as well as vonoprazan safety were evaluated after 2 weeks of EVL. Results Post-EVL ulcer bleeding occurred among 2.15% of vonoprazan, 8.7% of pantoprazole, and 14.2% of the non-acid suppression groups (P < 0.001). Post-ligation ulcer frequency and dimensions were higher among non-acid suppression and pantoprazole groups vs. vonoprazan (P < 0.05). Chest pain and odynophagia were encountered among 73.6% and 54.9% of the non-acid suppression group vs. 39.6% and 45.1% in pantoprazole, and 17.2% and 21.5% in vonoprazan groups, respectively (P < 0.05). There were no vonoprazan-related adverse events. Non-use of vonoprazan was the strongest independent predictor for post-EVL bleeding. Conclusion Short course of vonoprazan 20 mg/day is safe and superior to pantoprazole 40 mg/day in the reduction of post-EVL ulcer dimensions at 2 weeks post-EVL, and prevention of ulcer-related bleeding. Acid suppression is superior to no acid suppression to prevent post-EVL complications.

Abstract
BACKGROUND Keverprazan is a novel potassium-competitive acid blocker for the treatment of acid-related diseases. AIMS To evaluate the safety, pharmacokinetics, pharmacodynamics, and food effect of single oral doses of keverprazan in healthy Chinese subjects. METHODS In the dose-escalated phase Ia trial, the first 8 subjects received keverprazan 5 mg, the others successively entered 10 mg, 20 mg, 40 mg, 60 mg groups and were randomized to receive keverprazan (n = 8), lansoprazole (LSZ) 30 mg (n = 2) or placebo (n = 2) in each dose group. The phase Ib study randomly enrolled subjects to the fasting-fed (n = 7) or fed-fasting (n = 7) groups for evaluating the food effect of keverprazan. RESULTS Twenty (35.71%) adverse events (AEs) occurred in phase Ia, including 13 (32.50%), 3 (37.50%), and 4 (50.00%) AEs in the keverprazan, placebo, and LSZ groups, respectively. Four (28.57%) AEs occurred in Phase Ib. The Tmax of keverprazan was 1.25-1.75 h. Cmax and AUC increased with the dose, and the t1/2, CL/F were 6.00-7.17 h, 88.8-198 L/h, respectively. The intragastric pH >5 holding-time ratio (HTR) increased with the dose but reached a ceiling at 20 mg. In the 30 mg LSZ and 5-60 mg keverprazan groups, the intragastric pH >5 HTRs during 24 h were 57.1%±26.4%, 7.9%±8.1%, 26.2%±22.8%, 80.2%±8.8%, 88.1%±8.6%, and 93.0%±1.7%, respectively. The geometric mean ratios (90% CI) of Cmax and AUC0-∞ of keverprazan in plasma under the fed vs. fasting state were 126.8% (109.0%-147.5%) and 134.9% (123.8%-146.9%). CONCLUSION Keverprazan is tolerable, and provides significant stable and lasting inhibition efficacy of intragastric acidity at 20 mg.

Abstract
Keverprazan, a novel potassium-competitive acid blocker, was approved for treating acid-related diseases. This study aimed to analyze the safety, pharmacokinetics (PKs) and pharmacodynamics (PDs) of multiple doses of keverprazan. This was a randomized, positive-/placebo-controlled, phase Ic trial. Twenty-six healthy adults were randomized to receive 20 mg/day keverprazan (n = 8), 40 mg/day keverprazan (n = 8), placebo (n = 6), or 20 mg/day vonoprazan (n = 4) for 7 days. Safety, PK and PD assessments were conducted. In the keverprazan, vonoprazan, and placebo groups, adverse events (AEs) were reported in nine (56.25%), two (50.00%), and three (50.00%) subjects, respectively. AEs were mild except a moderate abdominal pain leading to withdraw. No serious AEs occurred. The plasma concentration-time profiles of keverprazan showed rapid absorption (median time to maximum plasma concentration of 1.25-3.0 h). The terminal half-life was 6.23 and 7.01 h for keverprazan 20 and 40 mg groups on day 7. The maximum plasma concentration was 43.1 and 93.2 ng/mL, respectively. There was no apparent accumulation of keverprazan and the major metabolite after 7-day administration. The intragastric pH greater than 5 holding time ratios (HTRs) over 24 h postdose increased from 79.1%, 84.4%, and 84.5% on day 1 to 99.0%, 97.4%, and 100.0% on day 7 in the vonoprazan 20 mg and keverprazan 20 and 40 mg groups, respectively. The intragastric pH greater than 5 HTR of keverprazan reached a plateau at 20 mg. Keverprazan is well-tolerable. A steady-state in exposure was generally reached after 7 days of treatment. A dose of 20 mg/day keverprazan can elicit a significant, stable, and long-lasting gastric acid inhibition effect.

Abstract
Quadruple therapy comprising 2 antibiotics, a proton pump inhibitor, and bismuth, is recommended for Helicobacter pylori eradication in China. This Phase 1, double-blind, parallel-group study aimed to evaluate the pharmacokinetics, safety, and tolerability of bismuth-containing vonoprazan- or esomeprazole-based quadruple therapy in H. pylori-positive healthy subjects at a single site in China. Quadruple therapy comprising vonoprazan 20 mg or esomeprazole 20 mg with bismuth potassium citrate 600 mg (equivalent to bismuth 220 mg), clarithromycin 500 mg, and amoxicillin 1000 mg was administered twice daily for 2 weeks. Forty-four subjects were enrolled, 22 each in the vonoprazan (mean age, 34.5 years; men, 63.6%) and esomeprazole (mean age, 31.6 years; men, 59.1%) groups. Day 14 bismuth plasma pharmacokinetic parameters area under the plasma concentration-time curve during a dosing interval (geometric mean ratio, 1.07 [90% confidence interval, 0.82-1.40]) and maximum observed plasma concentration (geometric mean ratio, 1.30 [90% confidence interval, 0.94-1.81]) were similar between the treatment groups. At Day 42 follow-up, 100% and 94.4% of subjects were H. pylori negative in the vonoprazan and esomeprazole groups, respectively. The incidence of treatment-emergent adverse events was similar between the groups, with no serious adverse events. No new safety concerns were identified. In conclusion, vonoprazan had no significant effect on plasma bismuth exposure compared with esomeprazole.

Abstract
Peptic ulcer disease (PUD) continues to be a cause of significant morbidity and mortality worldwide. Almost two-thirds of PUD cases are asymptomatic. In symptomatic patients, epigastric pain is the most common presenting symptom of PUD, which is manifested by nausea, abdominal fullness, bloating, and dyspepsia. Most PUD cases are associated with the use of COX inhibitors or Helicobacter pylori infection, or both. The traditional management of PUD includes the use of proton pump inhibitors to reduce the gastric acid secretion and antibacterial drugs to combat H. pylori. Timely diagnosis and treatment of PUD are vital to reduce the risk of associated morbidity and mortality, as is prevention of PUD among patients at high risk, including COX inhibitors users and those infected with H. pylori. PDE5 inhibitors have been used for the management of erectile dysfunction and pulmonary hypertension for decades. In recent years, studies have mentioned tremendous pleiotropic effects of PDE5 inhibitors on gastrointestinal, urogenital, musculoskeletal, reproductive, cutaneous, and neurologic disorders. Recent data shows that PDE5 inhibition augments gastric mucosa protection, and here, we review the most recent findings regarding the use of PDE5 inhibitors for the prevention and management of PUD.

Abstract
ATP12A encodes the catalytic subunit of the non-gastric proton pump, which is expressed in many epithelial tissues and mediates the secretion of protons in exchange for potassium ions. In the airways, ATP12A-dependent proton secretion contributes to complex mechanisms regulating the composition and properties of the fluid and mucus lining the respiratory epithelia, which are essential to maintain the airway host defense and the respiratory health. Increased expression and activity of ATP12A in combination with the loss of other balancing activities, such as the bicarbonate secretion mediated by CFTR, leads to excessive acidification of the airway surface liquid and mucus dysfunction, processes that play relevant roles in the pathogenesis of cystic fibrosis and other chronic inflammatory respiratory disorders. In this review, we summarize the findings dealing with ATP12A expression, function, and modulation in the airways, which led to the consideration of ATP12A as a potential therapeutic target for the treatment of cystic fibrosis and other airway diseases; we also highlight the current advances and gaps regarding the development of therapeutic strategies aimed at ATP12A inhibition.

[PMID: 37834761 PMCID: PMC10573336 DOI: 10.3390/jcm12196116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/08/2023] [Accepted: 09/19/2023] [Indexed: 10/15/2023] Open
Abstract
Tegoprazan is a novel, potent, and highly selective potassium-competitive acid blocker that inhibits gastric acid secretion with rapid onset of action and prolonged control of gastric acidity. We performed a preliminary feasibility study to evaluate whether tegoprazan could control symptoms more effectively than a placebo in patients with laryngopharyngeal reflux disease (LPRD). In this double-blind, randomized, placebo-controlled trial, 35 patients with LPRD were randomly assigned to two groups: tegoprazan 50 mg daily and placebo. The primary endpoint was the complete resolution rate of LPRD symptoms after 8 weeks of medication, and the secondary endpoints were the complete resolution rate of LPRD symptoms after 4 weeks of medication and changes in the reflux symptom index (RSI) and reflux finding score (RFS) from baseline at 4 and 8 weeks of medication. There was no difference in the complete symptom resolution rates at 8 weeks between the tegoprazan and placebo groups (29.4% [5/17] vs. 27.8% [5/18], p = 1.000). Moreover, there was no significant difference in the complete symptom resolution rates at 4 weeks between the two groups. Compared with the baseline, both tegoprazan and placebo significantly reduced the total RSI and RFS scores after 4 and 8 weeks of medication; however, tegoprazan was not superior to the placebo. In conclusion, tegoprazan (50 mg daily) administration improved LPRD symptoms and signs. However, tegoprazan did not show superiority over placebo. Considering the potential effectiveness of tegoprazan as an acid-suppressing therapy and the possibility of type II error due to a low number of included patients herein, prospective, large-scale, multi-center studies with a higher dose of tegoprazan for a prolonged duration are required to elucidate the efficacy of tegoprazan in patients with LPRD.

Pharmaceuticals (Basel) 2023; 16:1141. [PMID: 37631056 PMCID: PMC10458111 DOI: 10.3390/ph16081141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 08/05/2023] [Accepted: 08/10/2023] [Indexed: 08/27/2023] Open
Abstract
Fexuprazan is a potassium-competitive acid blocker approved for treating gastric-acid-related diseases. Although the effectiveness of the recent formulation fexuprazan 10 mg has been demonstrated in Phase 3 clinical trials, data on the pharmacokinetics (PKs) of administering fexuprazan 10 mg twice daily at a 12 h interval are lacking. Moreover, it is imperative to ensure the bioequivalence of the new formulation with the previously approved 40 mg formulation. This study evaluated the pharmacokinetics (PKs) of the single- and multiple-dose oral administration of fexuprazan 10 mg tablets in healthy participants (Part 1) and investigated their bioequivalence with 40 mg tablets (Part 2). Part 1 comprised a single- and multiple-dose, one-sequence, two-period design and eight participants, while Part 2 comprised a single-dose, 2 × 2 crossover design and 24 participants. In Part 1, in Periods 1 and 2, participants received single and multiple doses (twice daily) of fexuprazan 10 mg, respectively. The maximum plasma concentration (Cmax) area under the concentration-time curve from 0 to 12 h (AUC0-12h) of the multiple-dose participants was approximately double that of the single-dose participants. In Part 2, the geometric mean ratios (90% confidence intervals) for Cmax and AUC from zero to the time of the last quantifiable concentration (AUClast) of the use of four fexuprazan 10 mg tablets to those of one fexuprazan 40 mg tablet were 1.0290 (0.9352-1.1321) and 1.0290 (0.9476-1.1174), respectively, meeting the bioequivalence criteria. Favorable PKs were observed after single and multiple administrations of one fexuprazan 10 mg tablet, and four fexuprazan 10 mg tablets were pharmacokinetically equivalent to one fexuprazan 40 mg tablet.

Abstract
Although discovered 40 years ago, Helicobacter pylori infection is still raising diagnostic and therapeutic problems today. The infection is currently managed based on statements in several guidelines, but implementing them in practice is a long process. Increasing antibiotic resistance and weak compliance of the patients limit the efficacy of eradication regimens, leaving much room for improvement. Third-generation proton pump inhibitors have added little to the results of the first two generations. Potassium-competitive acid blockers have a stronger and longer inhibitory action of acid secretion, increasing the intragastric pH. They obtained superior results in eradication when compared to proton pump inhibitors. Instead of innovative antibiotics, derivatives of existing antimicrobials were developed; some new fluoroquinolones and nitazoxanide seem promising in practice, but they are not recommended by the guidelines. Carbonic anhydrase inhibitors have both anti-secretory and bactericidal effects, and some researchers are expecting their revival in the treatment of infection. Capsules containing components of the eradication regimens have obtained excellent results, but are of limited availability. Probiotics, if containing bacteria with anti-Helicobacter pylori activity, may be useful, increasing the rates of eradication and lowering the prevalence and severity of the side effects.

Abstract
BACKGROUND Bismuth-based quadruple therapy (BQT) is recommended as the first-line empirical therapy for Helicobacter pylori eradication as it is not associated with resistance. However, few studies have investigated the use of potassium-competitive acid blockers for BQT. AIM To investigate the efficacy and safety profiles of tegoprazan-based BQT (TBMT) versus lansoprazole-based BQT (LBMT) for H. pylori eradication. METHODS We included patients older than 18 with an H. pylori infection without a history of H. pylori eradication who visited four university-affiliated hospitals between March 2020 and December 2021. H. pylori infection was diagnosed using a rapid urease test or Giemsa staining. Patients were randomly assigned to the TBMT or LBMT group. RESULTS 217 subjects were randomly allocated to receive either TBMT (n = 108) or LBMT (n = 109) therapy. Intention-to-treat (ITT) eradication rates of TBMT and LBMT were 80.0% and 77.4% (95% confidence interval [CI]: -8.4 to 13.7, p = 0.0124), respectively. Corresponding modified ITT rates were 90.3% and 84.5% (95% CI: -3.6 to 15.2, p = 0.0005), respectively. Per-protocol (PP) eradication rates of TBMT and LBMT were 90.2% and 82.4% (95% CI: -2.5 to 18.2, p = 0.0003), respectively. There was no significant difference in the rate of adverse events between the TBMT and LBMT groups (39.1% vs. 43.4%, p = 0.5211). TBMT showed higher eradication rates than that of LBMT in ITT, m-ITT, and PP analysis. CONCLUSION TBMT showed a noninferior eradication rate and similar adverse events to LBMT as a first-line eradication regimen. Our results suggest that tegoprazan might be substituted for proton pump inhibitors in H. pylori eradication regimens.

Abstract
BACKGROUND Zastaprazan (JP-1366) is a novel potassium-competitive acid blocker with favourable preclinical safety and efficacy profile being developed for the treatment of acid-related diseases. AIMS To investigate the safety, tolerability, pharmacodynamics and pharmacokinetics of zastaprazan. METHODS A randomised, open-label, placebo- and active-controlled, single and multiple ascending dose clinical trial was conducted in healthy Korean male subjects. Intragatric pH and serum gastrin were measured to assess the pharmacodynamics, while serial blood and urine samples were collected to assess the pharmacokinetics. Pharmacogenomic evaluation was conducted to explore genetic variants, which can affect the pharmacodynamics and pharmacokinetics. Safety and tolerability including hepatotoxicity were evaluated. RESULTS Suppression of gastric acid secretion increased as the dose of zastaprazan increased. The percentage of time that gastric pH was over 4 (%Time pH >4) with zastaprazan 20 mg (85.19%) and 40 mg (91.84%) were similar to or greater than that with esomeprazole 40 mg (72.06%). Zastaprazan was rapidly absorbed within 2 h and eliminated with a half-life of 6-10 h. Pharmacogenomic analysis found no genetic variant of drug metabolising enzymes including CYP2C19 or drug transporters associated with the exposure of zastaprazan. Zastaprazan was well tolerated with no clinically significant changes in safety and tolerability assessments. CONCLUSIONS Zastaprazan was safe and well tolerated after a single oral dose up to 60 mg and multiple oral doses up to 40 mg. It also showed rapid, potent suppression of gastric acid secretion. Pharmacodynamic and pharmacokinetic profile of zastaprazan was suitable for treatment of patients with acid-related diseases.

Abstract
BACKGROUND Vonoprazan is a potassium competitive acid blocker (P-CAB) approved in Japan in 2014 to treat endoscopic submucosal dissection (ESD)-induced ulcers and bleeding or perforation. Therefore, this meta-analysis aimed to determine whether Vonoprazan is more effective than Lansoprazole in the treatment of ESD-induced ulcers which include ulcer healing and shrinking rate, among others. METHODS Randomized controlled trials (RCT) and retrospective studies were collected from the PubMed (Medline), Embase, Web of science and Cochrane Library databases. Meanwhile, studies were selected according to predetermined qualification criteria and data were extracted by two researchers. The quality of the methods for published papers was evaluated using the modified Jadad scale. RESULTS Five studies were included in this meta-analysis, the ulcer healing rate effect was not significantly higher in the intervention groups than in the control groups at 4 weeks, [OR:1.07 (0.51, 2.22), 95% CI, I2=2%, Z=0.18, P=0.86]. There was no significant difference in the ulcer shrinkage rate at 4 weeks [MD:0.20 (-1.51, 1.92), 95% CI, I2=0%, P=0.82] and 8 weeks [MD: -0.09 (-0.30, 0.12), 95% CI, I2=0%, P=0.39]. CONCLUSION There was no significant difference between Vonoprazan and Lansoprazole in the ulcers induced by treatment after 4 weeks and 8 weeks of treatment with ESD.

Abstract
BACKGROUND AND OBJECTIVE CYP2C19-mediated drug interactions of acid-reducing agents are clinically important given the high possibility of concomitant administration with CYP2C19 substrates. This study aimed to evaluate the effect of tegoprazan on the pharmacokinetics (PK) of a CYP2C19 substrate, proguanil, compared with vonoprazan or esomeprazole. METHODS A two-part, randomized, open-label, two-sequence, three-period crossover study was conducted in 16 healthy CYP2C19 extensive metabolizers (eight subjects per part). In each period, a single oral dose of atovaquone/proguanil 250/100 mg was administered alone or co-administered with tegoprazan 50 mg, esomeprazole 40 mg (Part 1 only) or vonoprazan 20 mg (Part 2 only). The plasma and urine concentrations of proguanil and its metabolite, cycloguanil, were measured up to 48 h post-dose. PK parameters were calculated using a non-compartmental method and compared between administered alone and co-administered with tegoprazan, vonoprazan or esomeprazole. RESULTS Co-administration of tegoprazan did not significantly affect the systemic exposure of proguanil and cycloguanil. In contrast, co-administration of vonoprazan or esomeprazole increased proguanil systemic exposure and decreased cycloguanil systemic exposure, and the magnitude of the corresponding change was greater with esomeprazole co-administration than vonoprazan co-administration. CONCLUSION Tegoprazan, unlike vonoprazan and esomeprazole, exhibited negligible CYP2C19-mediated PK interaction. It suggests that as an alternative to other acid-reducing agents, tegoprazan can be used concomitantly with CYP2C19 substrates in clinical settings.

Abstract
Background/Aims Patients with gastroesophageal reflux disease (GERD) frequently experience nighttime heartburn and sleep disturbance. Tegoprazan is a new potassium-competitive acid blocker that can rapidly block acid secretion. This study aims to evaluate the efficacy of tegoprazan compared with esomeprazole in relieving nighttime heartburn and sleep disturbances. Methods Patients with erosive esophagitis, nighttime heartburn, and sleep disturbances were randomized to receive tegoprazan 50 mg or esomeprazole 40 mg for 2 weeks. The primary endpoint was time to first nighttime heartburn-free interval. The percentage of nighttime heartburn-free days was also compared between the 2 groups. Results A total of 46 patients were enrolled in this study. Time to the first nighttime heartburn-free interval was shorter with tegoprazan than with esomeprazole but the difference was not statistically significant (1.5 days vs 3 days, P = 0.151). The percentage of nighttime heartburn-free days was higher in the tegoprazan group but the difference was insignificant (57.8% vs 43.1%, P = 0.107). Adverse events occurred in 2 patients. They were mild in severity. Conclusions Tegoprazan may induce faster relief of nighttime heartburn symptoms and may improve sleep disorders associated with nighttime heartburn. Further large-scale studies are required to validate our findings.

Abstract
Background/Aims Tegoprazan, a novel potassium-competitive acid blocker, is expected to overcome the limitations of proton pump inhibitors and effectively control nocturnal acid breakthrough. To evaluate the pharmacodynamics of tegoprazan versus dexlansoprazole regarding nocturnal acid breakthrough in healthy subjects. Methods In a randomized, open-label, single-dose, balanced incomplete block crossover study, 24 healthy male volunteers were enrolled and randomized to receive oral tegoprazan (50, 100, or 200 mg) or dexlansoprazole (60 mg) during each of two administration periods, separated by a 7- to 10-day washout period. Blood samples were collected for pharmacokinetic parameter analysis; gastric monitoring was performed for pharmacodynamic parameter evaluation. Results All 24 subjects completed the study. Average maximum plasma concentration, area under the plasma concentration-time curve, and mean time with gastric pH >4 and pH >6 for tegoprazan demonstrated dose-dependent incremental increases. All the tegoprazan groups reached mean pH ≥4 within 2 hours, whereas the dexlansoprazole group required 7 hours after drug administration. Based on pharmacodynamic parameters up to 12 hours after evening dosing, 50, 100, and 200 mg of tegoprazan presented a stronger acid-suppressive effect than 60 mg of dexlansoprazole. Moreover, the dexlansoprazole group presented a comparable acid-suppressive effect with the tegoprazan groups 12 hours after dosing. Conclusions All the tegoprazan groups demonstrated a significantly faster onset of gastric pH increase and longer holding times above pH >4 and pH >6 up to 12 hours after evening dosing than the dexlansoprazole group.

Comparison of hepatotoxicity of tegoprazan, a novel potassium-competitive acid blocker, with proton pump inhibitors using real-world data: A nationwide cohort study. Front Med (Lausanne) 2023; 9:1076356. [PMID: 36714137 PMCID: PMC9876560 DOI: 10.3389/fmed.2022.1076356] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Accepted: 12/12/2022] [Indexed: 01/12/2023] Open
Abstract
Background Proton pump inhibitors (PPIs) are acid suppressants that are frequently prescribed in many countries to reduce heartburn. A potassium-competitive acid blocker (P-CAB; tegoprazan) was launched relatively recently that also inhibits gastric acid secretion. This study aimed to compare the hepatotoxicity of the six existing PPIs with P-CAB. Methods This retrospective cohort study was conducted between January 2019 and December 2020 and included data from the total population of 50 million inhabitants in Korea. Propensity score (PS) matching was performed using 10 variables, and the differences in hepatotoxicity between P-CAB and the six PPIs were compared in a similar distribution. The primary endpoint was hepatotoxicity which included toxic liver disease, hepatitis, hepatic failure, liver transplantation, and other liver diseases. Results The risk ratios (RR) of tegoprazan vs. the six PPIs (dexlansoprazole, esomeprazole, lansoprazole, omeprazole, pantoprazole, and rabeprazole) were all significant [RR: 0.70 (95% CI: 0.69-0.72), 0.81 (95% CI: 0.79-0.83), 0.61 (95% CI: 0.59-0.63), 1.17 (95% CI: 1.13-1.20), 0.61 (95% CI: 0.59-0.62), and 0.73 (95% CI: 0.71-0.75), respectively]. The risk ratio of tegoprazan vs. the six existing PPIs was 0.73 (95% CI: 0.72-0.75). The hazard ratios (HRs) of hepatotoxicity of the six PPIs to tegoprazan showed significantly higher values apart from omeprazole (HR: dexlansoprazole, 1.13; esomeprazole, 1.04; lansoprazole, 1.25; omeprazole, 0.77; pantoprazole, 1.26; rabeprazole, 1.15, respectively, and the six existing PPIs, 1.10). Conclusion Using a large-scale data cohort analysis consisting of 50 million Koreans, tegoprazan did not induce higher hepatotoxicity compared with the six conventional PPIs.

Abstract
Background Vonoprazan, a novel acid-suppressive drug, is non-inferior to proton pump inhibitors (PPIs) for the management of gastric acid-related diseases. However, the safety of vonoprazan has not been systematically evaluated yet. Objectives To elucidate the incidence and type of adverse events (AEs) in patients taking vonoprazan. Design Systematic review and meta-analysis. Data sources and methods PubMed, EMBASE, and Cochrane Library databases were searched for all studies reporting the safety of vonoprazan. The incidences of any AEs, drug-related AEs, serious AEs, AEs leading to drug discontinuation, and common AEs were pooled. Odds ratios (ORs) were calculated to compare the incidence of AEs between patients taking vonoprazan and PPIs. Results Seventy-seven studies were included. The pooled incidences of any AEs, drug-related AEs, serious AEs, and AEs leading to drug discontinuation were 20, 7, 1, and 1%, respectively. The incidences of any AEs (OR = 0.96, p = 0.66), drug-related AEs (OR = 1.10, p = 0.44), serious AEs (OR = 1.14, p = 0.36), and AEs leading to drug discontinuation (OR = 1.09, p = 0.55) were not significantly different between patients taking vonoprazan and PPIs. In subgroup analyses, patients with peptic ulcer disease (PUD) had higher incidences of any AEs, serious AEs, and AEs leading to drug discontinuation than those with gastroesophageal reflux disease (GERD), Helicobacter pylori (H. pylori) infection, and artificial ulcer after gastric endoscopic submucosal dissection (ESD), but patients with H. pylori infection had a higher incidence of drug-related AEs than those with PUD, GERD, and artificial ulcer after gastric ESD. The incidence of AEs was higher in patients taking long-term use of vonoprazan than those taking short-term use of vonoprazan. Conclusion Vonoprazan is well tolerated and shows similar safety compared to PPIs. The safety of vonoprazan may be primarily influenced by its indications and duration.

Abstract
BACKGROUND Tegoprazan is a novel potassium-competitive acid blocker used to treat acid-related disorders. AIM To compare tegoprazan 25 mg with lansoprazole 15 mg as maintenance therapy in healed erosive oesophagitis (EE) METHODS: In this phase 3, double-blind, multi-centre study, patients with endoscopically confirmed healed EE were randomised 1:1 to receive tegoprazan 25 mg or lansoprazole 15 mg once daily for up to 24 weeks. The primary efficacy endpoint was the endoscopic remission rate after 24 weeks. The secondary efficacy endpoint was the endoscopic remission rate after 12 weeks. Safety endpoints included adverse events, clinical laboratory results and serum gastrin and pepsinogen I/II levels. RESULTS We randomised patients to tegoprazan 25 mg (n = 174) or lansoprazole 15 mg (n = 177). Most had mild EE (Los Angeles (LA) grade A: 57.3%, LA grade B: 37.3%). The endoscopic remission rate after 24 weeks was 90.6% with tegoprazan and 89.5% with lansoprazole. Tegoprazan was not inferior to lansoprazole for maintaining endoscopic remission at 24 weeks and 12 weeks. In subgroup analysis, tegoprazan 25 mg showed no significant difference in maintenance rate according to LA grade (p = 0.47). The maintenance effect of tegoprazan was consistent in CYP2C19 extensive metabolisers (p = 0.76). Increases in serum gastrin were not higher in tegoprazan-treated than lansoprazole-treated patients. CONCLUSIONS Tegoprazan 25 mg was non-inferior to lansoprazole 15 mg in maintenance of healing of mild EE. In this study, tegoprazan had a similar safety profile to lansoprazole.

Abstract
Proton pump inhibitors (PPIs) have several limitations to their efficacy including insufficient acid suppression, slow onset of action, and variable efficacy among patients due to CYP2C19 metabolism. Potassium-competitive acid blockers inhibit H+-K+-ATPase in a reversible and K+-competitive manner, are novel acid suppressive drugs with rapid onset of action, meal independence, and prolonged control of intragastric acidity compared to PPIs. Potassium-competitive acid blockers exhibited non-inferior therapeutic efficacies on reflux esophagitis, gastric ulcers, and Helicobacter pylori eradication. The review is focused on the unmet needs across the acid-related diseases and recent updates on clinical studies using vonoprazan and tegoprazan.

Abstract
BACKGROUND The pharmacokinetic and clinical behaviors of many proton pump inhibitors (PPIs) in peptic ulcer treatment are altered by CYP2C19 genetic polymorphisms. This non-inferiority study evaluated the efficacy and safety of the novel PPI anaprazole compared with rabeprazole. We also explored the influence of Helicobacter pylori ( H. pylori ) infection status and CYP2C19 polymorphism on anaprazole. METHODS In this multicenter, randomized, double-blind, double-dummy, positive-drug parallel-controlled, phase III study, Chinese patients with duodenal ulcers were randomized 1:1 to receive rabeprazole 10 mg + anaprazole placebo or rabeprazole placebo + anaprazole 20 mg once daily for 4 weeks. The primary efficacy endpoint was the 4-week ulcer healing rate assessed by blinded independent review. Secondary endpoints were the proportion of patients with improved overall and individual duodenal ulcer symptoms at 4 weeks. Furthermore, exploratory subgroup analysis of the primary endpoint by H. pylori status and CYP2C19 polymorphism was conducted. Adverse events were monitored for safety. Non-inferiority analysis was conducted for the primary endpoint. RESULTS The study enrolled 448 patients (anaprazole, n = 225; rabeprazole, n = 223). The 4-week healing rates were 90.9% and 93.7% for anaprazole and rabeprazole, respectively (difference, -2.8% [95% confidence interval, -7.7%, 2.2%]), demonstrating non-inferiority of anaprazole to rabeprazole. Overall duodenal ulcer symptoms improved in 90.9% and 92.5% of patients, respectively. Improvement rates of individual symptoms were similar between the groups. Healing rates did not significantly differ by H. pylori status or CYP2C19 genotype for either treatment group. The incidence of treatment-emergent adverse events was similar for anaprazole (72/220, 32.7%) and rabeprazole (84/219, 38.4%). CONCLUSIONS The efficacy of anaprazole is non-inferior to that of rabeprazole in Chinese patients with duodenal ulcers. REGISTRATION ClinicalTrials.gov, NCT04215653.

Abstract
Potassium-competitive acid blockers (PCABs) such as vonoprazan represent a novel class of acid suppressants that show tremendous promise to enhance care of acid peptic disorders. PCAB characteristics distinct from those of proton pump inhibitors-such as acid stability with dosing independent of food consumption, rapid onset of action, less variability with CYP2C19 polymorphisms, and extended half-lives-may add value in clinical practice. With recently reported data beyond Asian populations and expanding regulatory approval of PCABs, clinicians should be aware of these medications and their potential roles in the management of acid peptic disorders. This article provides an up-to-date summary of the evidence around PCABs for the treatment of gastroesophageal reflux disease (especially erosive esophagitis healing and maintenance), eosinophilic esophagitis, Helicobacter pylori infection, and peptic ulcer healing and secondary prophylaxis.

Abstract
BACKGROUND AND AIM The influence of gastric acid inhibitors (GAIs) on nonsteroidal anti-inflammatory drug (NSAID)-induced enteropathy is controversial. Herein, the influences of different GAIs on NSAID-induced intestinal injury and the underlying mechanisms are clarified. METHODS Indomethacin (IND; 10 mg/kg/day) was administered to mice to induce small intestinal injury. Disease activity was examined macroscopically and histologically. The permeability of small intestine was evaluated by measuring plasma lipopolysaccharide levels. 16S rDNA sequencing was performed to determine the composition of intestinal flora. RESULTS Among the four GAIs, ilaprazole (IPZ) significantly attenuated IND-induced small intestinal injury and maintained the integrity of the mucosal barrier. Omeprazole (OPZ) and vonoprazan (VPZ) ameliorated ulceration without significant differences, while rabeprazole (RPZ) failed to protect against the injury. To explore the potential mechanism, we investigated changes in the gut microbiota mediated by GAIs. After 5-day administration, GAIs significantly altered the composition of the gut microbiota. The IND group had a significant decrease in alpha diversity compared with the control group, and this decrease was reversed by OPZ and IPZ treatment, respectively. After IPZ treatment, the community membership was more assembled in the control group than the IND group. Further, we found that Lactobacillus was significantly increased in the groups of OPZ, IPZ, and VPZ, while Bacteroides was significantly increased in the RPZ group. CONCLUSION Our results indicated that GAIs have different influences on the mucosal barrier, possibly by altering the composition of intestinal microbiota, and the impacts mediated by various GAIs in the IND-induced intestinal damage model seem different.

Abstract
YH4808 is a novel potassium‐competitive acid blocker that is under clinical development to treat patients with gastroesophageal reflux disease and peptic ulcer diseases. In this study, the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of YH4808 were modeled in healthy male volunteers who received a single oral dose of YH4808 at 30, 50, 100, 200, 400, 600, and 800 mg or matching placebo and multiple once‐daily oral doses of YH4808 at 100, 200, and 400 mg or matching placebo for 7 days. A population PK–PD model adequately described the time–concentration‐effect profiles of YH4808. The maximum increasing effect of YH4808 on intragastric pH was 4.38, which was higher than the observed maximum increase in intragastric pH after omeprazole at 40 mg (2.2 in pH). The maximum inhibitory effect by the increased intragastric pH on the exposure to repeated YH4808 was 58% from baseline. Monte–Carlo simulation experiments based on the final model showed that YH4808 at 200 mg will produce a higher percentage of time at pH > 4 over 24 h on day 1 than observed value of esomeprazole at 40 mg once‐daily, an active comparator (84.7% time vs. 58.3% time, respectively). Because YH4808 at ≥200 mg resulted in a higher percentage of time at intragastric pH > 4 than seen after once‐daily esomeprazole at 40 mg and YH4808 showed acceptable tolerability at a single‐dose of 30–800 mg, we suggest to test the 200 mg once daily dosage regimen in further clinical trials of YH4808.

Cho JH, Jin SY. Current guidelines for Helicobacter pylori treatment in East Asia 2022: Differences among China, Japan, and South Korea. World J Clin Cases 2022; 10:6349-6359. [PMID: 35979311 PMCID: PMC9294908 DOI: 10.12998/wjcc.v10.i19.6349] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 03/11/2022] [Accepted: 05/08/2022] [Indexed: 02/06/2023] Open
Abstract
Helicobacter pylori (H. pylori) infection is highly prevalent in East Asia. The overall seroprevalence rate of H. pylori infection is 44.2% in China, 37.6%-43.2% in Japan, and 51.0% in South Korea. H. pylori can cause peptic ulcer disease and gastric cancer. East Asian countries have high rates of gastric cancer (age-standardized incidence rate: 20-30 per 100000). The Kyoto global consensus report emphasized that H. pylori gastritis should be considered the main cause for the development of gastric cancer. H. pylori treatment guidelines in China, Japan, and South Korea have recently been revised according to data from each of those countries. However, emerging antibiotic resistance is an important barrier to H. pylori eradication. The recommended H. pylori treatment regimens differ among those three East Asian countries. In this review, recent guidelines and up-to-date research on H. pylori treatment regimens from China, Japan, and South Korea are discussed.

Abstract
Histamine H<sub>2</sub> receptor antagonists (H<sub>2</sub>RAs) suppress gastric acid production by blocking H<sub>2</sub> receptors in parietal cells. Studies have shown that proton pump inhibitors (PPIs) are superior to H<sub>2</sub>RAs as a treatment for acid-related disorders, such as peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD). PPIs reduce gastric acid production by irreversibly inhibiting the H<sup>+</sup>/K<sup>+</sup> ATPase pump, and they also increase gastric emptying. Although PPIs have differing pharmacokinetic properties, each PPI is effective in managing GERD and PUDs. However, PPIs have some limitations, including short plasma half-lives, breakthrough symptoms (especially at night), meal-associated dosing, and concerns associated with long-term PPI use. Potassium-competitive acid blockers (P-CABs) provide more rapid and profound suppression of intragastric acidity than PPIs. P-CABs are non-inferior to lansoprazole in healing erosive esophagitis and peptic ulcers, and may also be effective in improving symptoms in patients with non-erosive reflux disease. Acid suppressive drugs are the most commonly used drugs in clinical practice, and it is necessary to understand the pharmacological properties and adverse effects of each drug.

Abstract
Helicobacter pylori infects nearly one-third of the US population. H pylori is a significant cause of gastroduodenal disease, including peptic ulcers and cancers. However, rising antibiotic resistance has complicated management of H pylori. This article provides a practical review of management strategies, including first-line empiric therapies and how to treat patients when prior therapies fail. Bismuthbased quadruple therapy remains the standard initial empiric regimen, although a rifabutin-based triple regimen is another approach for empiric therapy in the United States. Clarithromycin and levofloxacin therapies should be avoided except when treating a strain of known susceptibility. When therapies fail, resistance should be tested with molecular or culture-based methods. Knowing local resistance patterns and/or using practice-based eradication rates is important for devising logic-based clinical choices. Ultimately, shared decision-making, patient counseling, and careful attention to drug type and dosage are essential for refractory cases.
