• Dual vonoprazan and amoxicillin therapy for Helicobacter pylori infection in Uruguay

  This trial tests whether a two-drug regimen (vonoprazan and amoxicillin for 14 days) can be as effective as the standard four-drug regimen for eradicating H. pylori in adults in Uruguay, with fewer side effects.

  Recruiting at 3 sites Phase 4 Hospital de Clínicas Dr. Manuel Quintela · Maldonado, Departamento de Maldonado and 3 other locations · NCT07924098

• Dual-drug therapy with linlarase glutarate and amoxicillin vs bismuth quadruple therapy for first-line Helicobacter pylori eradication

  This trial tests whether a dual-drug regimen of linlarase glutarate capsules plus amoxicillin can match the effectiveness of a standard bismuth-containing quadruple therapy for first-line Helicobacter pylori eradication.

  Recruiting at 24 sites Phase 4 Xijing Hospital of Digestive Diseases · Zhengzhou, Henan and 23 other locations · NCT07897994

• Feasibility of FFPE qPCR to Detect H. pylori and Clarithromycin Resistance

  This study tests whether tissue samples already collected during gastroscopy can be used with qPCR to find Helicobacter pylori and its clarithromycin resistance.

  Recruiting Clinique Bizet · Paris · NCT07821294

• Adding bismuth to vonoprazan‑amoxicillin therapy for H. pylori

  This study will test whether adding bismuth to a 14-day vonoprazan‑amoxicillin regimen improves H. pylori cure rates in adults who have never had eradication therapy.

  Recruiting Phase 3 National Taiwan University Hospital · Taipei · NCT07576959

• Endoscopic screening for H. pylori, intestinal metaplasia, and Barrett's mucosa during screening colonoscopy

  This project will try adding a gastroscopy with biopsies to routine screening colonoscopy to see how often H. pylori and early stomach changes appear in adults without upper GI symptoms.

  Recruiting Sigmund Freud PrivatUniversitat · Vienna · NCT07346521

• Registry for managing Helicobacter pylori infection in Shandong Province

  This registry will collect real-world information on H. pylori treatments given to adults in Shandong Province to see which approaches work best and are safest.

  Recruiting Qilu Hospital of Shandong University · Jinan, Shandong and 1 other locations · NCT07335406

• Treating H. pylori infection to help metabolic syndrome by changing gut bacteria.

  This study will see if adding a probiotic or berberine to standard H. pylori treatment helps adults with H. pylori infection and newly diagnosed metabolic syndrome improve blood sugar, cholesterol, weight, and other metabolic measures.

  Recruiting Phase 4 Nanjing First Hospital, Nanjing Medical University · Nanjing, Jiangsu · NCT07306988

• Vonoprazan versus a proton pump inhibitor with vitamin D or probiotics added to triple antibiotics for H. pylori eradication

  This trial tests whether replacing a PPI with vonoprazan and adding vitamin D or a probiotic to standard clarithromycin–amoxicillin therapy helps adults with H. pylori infection clear the bacteria.

  Recruiting Phase 2 Tanta University · Shibīn al Kawm · NCT07293910

• Proton Pump Inhibitor vs Vonoprazan Triple Therapy for H. pylori Eradication, With or Without Zinc

  This trial tests whether a vonoprazan-based triple therapy (with or without zinc) can safely and more effectively eradicate H. pylori compared with a traditional proton-pump inhibitor-based triple therapy in adults.

  Recruiting Phase 3 Tanta University · Shibīn al Kawm · NCT07275827

• Diagnosing Helicobacter pylori in children using a stool test

  This project will test whether a stool-based PCR can detect Helicobacter pylori and identify clarithromycin resistance in children who are having gastroscopy with biopsies.

  Recruiting Poitiers University Hospital · Poitiers · NCT07083804

• Comparing different treatment durations for Helicobacter pylori eradication

  This study is testing how well different treatment lengths of two types of medications can get rid of Helicobacter pylori in people with the infection.

  Recruiting Phase 4 Shandong University · Jinan, Shandong · NCT06723197

• Preventing gastric cancer mortality through H. Pylori eradication and pepsinogen testing

  This study is testing if treating Helicobacter pylori infections and monitoring stomach health can help lower the risk of gastric cancer in middle-aged people living in high-risk areas.

  Recruiting Phase 4 International Agency for Research on Cancer · Riga · NCT02047994
