To investigate the impacts of antibiotic resistance of H. pylori as well as CYP3A4, CYP2C19 and IL-1B -511 genotypes of host on the eradication efficacies of anti-H. pylori treatments...
A Modular Phase I, Open-label Study to Assess the Safety, Pharmacokinetics, and Drug Interaction Potential and Relative Bioavailability of Saruparib in Patients With Advanced Solid Malignancies
Summary: A Phase I modular study to assess the effect of oral saruparib on other treatments in patients with advanced solid malignancies.
A Multi-centre, Randomized, Double-Blind, Double-Dummy, Parallel-Group, Phase 4 Efficacy and Safety Study of P-CAB (Tegoprazan 50 mg Once Daily) Compared With PPI (Rabeprazole 20 mg Once Daily) to Reduce Upper Gastrointestinal Events Including Bleeding and Symptomatic Ulcer Disease
Summary: The primary aim of this study is to evaluate the efficacy and safety of novel P-CAB (tegoprazan 50 mg once daily) as compared with standard PPI (rabeprazole 20 mg once daily) for protection of GI events in patients with known cardiac and vascular disease receiving chronic use of antithrombotic drugs (either antiplatelets, OAC, and its combinations) who are at high GI bleeding risk. The primary hyp...
A Phase 1, Open-label, Randomized, Four-way Crossover Study to Assess the Relative Bioavailability of Two Phase 3 LY4100511 (DC-853) Tablet Formulations Compared With the Phase 2 LY4100511(DC-853) Tablet Formulation, With and Without a Proton Pump Inhibitor in Healthy Participants
Summary: The main purpose of this study is to compare the bioavailability of 3 different formulations of LY4100511 and if the use of a proton pump inhibitor (PPI) alters the bioavailability of the 3 different formulations.
Efficacy and Safety of Anaprazole in the Treatment of Reflux Esophagitis: A Multicenter, Randomized, Double-Blind, Double-Dummy, Parallel-Group, Positive-Controlled Phase III Clinical Trial.
Summary: This Phase III clinical trial is designed to assess the efficacy and safety of Anaprazole 60 mg once daily (QD) administered over a period of up to 8 weeks, compared with Rabeprazole 20 mg QD, in patients with reflux esophagitis.
A Phase 1, Open-label, 3-Period, Randomized 2-Sequence Study to Evaluate the Effect of Food and a Proton Pump Inhibitor on the Pharmacokinetics of VRN110755 in Healthy Adult Participants
Summary: This is a Phase 1, open-label, randomized, single-center study to evaluate the effect of food and a proton pump inhibitor (PPI) on the pharmacokinetics (PK) of VRN110755 in healthy adult participants. The primary aim of this study is to assess the impact of food and rabeprazole co-administration on the systemic exposure of VRN110755. Safety and tolerability will also be evaluated.
Efficacies of Susceptibility-guided vs Empiric Therapy for Rescue Treatment of Helicobacter Pylori Infection - A Prospective Randomized, Comparative Study
Summary: The prevalence of H. pylori antibiotic resistance has reached an alarming level worldwide. Antibiotic stewardship programs should be urgently developed and implemented. However, H. pylori antimicrobial susceptibility testing (AST) is rarely offered, making local resistance patterns not easily available. Guideline-recommended empiric therapies (GR-ET) may no longer reliably achieve high cure rate i...
Potassium-Competitive Acid Blocker Versus Proton Pump Inhibitor as A Part of Bismuth Based Quadruple Therapy for Treatment of Helicobacter Pylori Infection: A Randomized Controlled Trial
Summary: This study aims to compare the eradication rate, safety, and patient adherence between potassium-competitive acid blockers (P-CABs) and proton pump inhibitor-based bismuth quadruple therapy in patients with Helicobacter pylori infection.
A Phase 1, Single-Sequence, 3 Period Crossover, Open-Label Study to Determine the Effect of Rabeprazole or H2 Blocker Famotidine on the Pharmacokinetics of Nirogacestat in Healthy Adult Male Participants
Summary: This study will evaluate the effects of the H2 blocker famotidine or the PPI rabeprazole on the PK of nirogacestat in healthy male participants
Efficacy and Safety of Keverprazan-amoxicillin Dual Therapy for Helicobacter Pylori First-line Treatment
Summary: This is an open-label, randomized controlled study. The study plans to enroll 414 subjects with Helicobacter pylori infection, who will be randomly assigned to the experimental group (Keverprazan dual therapy for 10 days or Keverprazan dual therapy for 14 days) or the control group (Rabeprazole quadruple therapy for 14 days) at a ratio of 1:1:1.
