Recruiting studies
- NCT06917963Recruiting

Study of afimkibart and other medicines in ulcerative colitis
This study looks at how afimkibart affects the way your body processes certain other medicines. It is for people with moderate to severe ulcerative colitis and helps researchers understand how to use this treatment safely.
Chula Vista, CaliforniaAges 18–60 - NCT07156201RecruitingPhase 1
Safety study of oral ABS-1230 in healthy adults
This trial tests a new oral medication called ABS-1230 in healthy people to see how safe it is and how the body processes it. You would take either the drug or a placebo (no active ingredient) and be monitored closely.
Sydney, New South WalesAges 18–55 - NCT06114836Recruiting
Feeding therapy for GERD in infants born early
This study tests whether a special feeding method can help infants in the NICU who have been diagnosed with GERD (acid reflux) using a probe that measures acid and non-acid reflux. It aims to find a treatment that may reduce reflux symptoms without medication.
Columbus, OhioAges 1 day–8 months - NCT06562907RecruitingPhase 1
Study of GS-4571 in healthy people, people with obesity, and people with type 2 diabetes
This trial tests an experimental drug called GS-4571 in three groups: healthy individuals, people with obesity (but not diabetes), and people with type 2 diabetes who are not obese. The study aims to see how the drug affects the body and how safe it is.
Miami, FloridaAges 18–55 - NCT06510010RecruitingPhase 2
Chemo plus H. pylori treatment for advanced stomach cancer
This trial tests whether adding H. pylori bacteria treatment to standard chemotherapy (before and after surgery) can improve outcomes for people with locally advanced stomach cancer. It combines oxaliplatin and S-1 chemo with antibiotics to clear the infection.
GuangzhouAges 18–75 - NCT06539494RecruitingPhase 2
Fructose and Fatty Liver Study (MARTINI)
This study looks at how the body handles a sugar called fructose in people with and without fatty liver disease. It aims to understand how fructose contributes to liver fat buildup.
AmsterdamAges 18–65 - NCT06861478RecruitingPhase 2
PPIs for bleeding varices in liver disease
This trial tests whether proton pump inhibitors (PPIs) can help people with cirrhosis who are hospitalized for variceal bleeding. It looks at whether PPIs reduce complications during the hospital stay.
Monterrey, Nuevo LeónAges 18 years+ - NCT04337580RecruitingPhase 2
Test a fatty-acid drug for docetaxel-resistant prostate cancer
This Phase 2 study tests whether blocking fatty-acid production can slow castration-refractory prostate cancer that has already progressed after docetaxel. It may help by targeting cancer growth when standard hormone-level treatments are no longer working.
Salisbury, North CarolinaAges 18 years+ - NCT05517928Recruiting
Probiotic trial to help gut changes caused by acid-reducing pills
This study tests whether a probiotic called Lactobacillus rhamnosus GG can improve gut bacteria changes caused by proton pump inhibitors (acid-reducing medicines). It mainly involves people who are otherwise healthy and do not currently have ongoing stomach or gut symptoms.
Scottsdale, ArizonaAges 18 years+ - NCT05799105RecruitingPhase 4
Open vs intact capsule acid reducers for marginal ulcers
This study compares two ways of taking acid-reducing medicine (proton pump inhibitors) for marginal ulcers that occur after gastric bypass. It may help decide which form works best to heal ulcers and prevent symptoms from coming back.
Cleveland, OhioAges Any age - NCT06150898RecruitingPhase 2
Ketorolac and pregabalin for estrogen receptor positive breast cancer before surgery
This trial tests whether two medications, ketorolac (a pain reliever) and pregabalin (a nerve pain drug), can help treat estrogen receptor (ER) positive breast cancer when taken before surgery. It may offer better pain control and possibly improve cancer outcomes.
Brussels, Brussels CapitalAges 18–70 - NCT06383338RecruitingPhase 1
Metabolism Changes in Young People with Lymphoma

Melbourne, VictoriaAges 6–25 - NCT06393868RecruitingPhase 3
Preventing stomach bleeding with omeprazole during blood thinner therapy
This trial tests whether omeprazole (a stomach acid reducer) can help prevent stomach bleeding in older adults who are taking blood thinners for a newly diagnosed blood clot. It may be a good fit if you are 65 or older and starting blood thinners for a clot.
Ottawa, OntarioAges 65 years+ - NCT06999577RecruitingPhase 4
The Mechanism Versus PPI Trial for throat reflux
This study tests how well omeprazole (a common acid-blocking medicine) works for people with laryngopharyngeal reflux (LPR), a condition where stomach acid irritates the throat. If you have had throat symptoms for more than 8 weeks and are already scheduled for an endoscopy with acid monitoring, you may qualify to see if this medicine helps more than a placebo.
San Deigo, CaliforniaAges 18–89 - NCT07037888RecruitingPhase 4
Ketorolac for pain after hip arthroscopy

Common questions
- Are there clinical trials studying Omeprazole?
- Yes. Clin2 currently lists 20 recruiting studies that include Omeprazole, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Omeprazole trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Omeprazole an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Omeprazole or a specific trial is right for you.
