Recruiting studies
- NCT06239272RecruitingPhase 1/Phase 2
Personalized treatment for NRSTS in children and young adults
This trial tests a personalized treatment plan for children and young adults with a type of soft tissue sarcoma (NRSTS). It uses a combination of surgery, targeted radiation, and two drugs (pazopanib and selinexor) to fight cancer while reducing side effects. The study is looking for people who have not been treated before for this sarcoma.
Atlanta, GeorgiaAges Up to 30 years - NCT03596476Recruiting
Test for reflux causes after proton pump pills fail
This study checks whether a special test of the esophagus after meals can find the exact reason for ongoing reflux symptoms when proton pump pills (PPIs) don’t help. It may help doctors choose the right next treatment for people whose reflux symptoms keep coming back.
Chambray-lès-ToursAges 18 years+ - 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+ - NCT07293910RecruitingPhase 2
Comparing treatments for H. pylori infection
This trial tests whether a new type of acid-reducing drug (vonoprazan) works better than a common one (proton pump inhibitor) when combined with vitamin D or probiotics to clear H. pylori, a bacteria that can cause stomach problems. If you have H. pylori and haven't been treated for it before, this study may be for you.
TantaAges 18–80 - NCT03049072Recruiting
Registry for people treated with ion beam therapy at MedAustron
This trial is a patient registry that collects information from people treated with ion beam therapy at MedAustron. It helps researchers understand treatment patterns and outcomes and may improve care for future patients.
Wiener Neustadt, Lower AustriaAges Any age - NCT07165444Recruiting
Comparing two acid-blocking drugs for H. pylori treatment
This trial tests if a newer acid-blocking medicine works better than a standard one when given with antibiotics and bismuth for treating H. pylori infection, a bacteria that can cause stomach ulcers. It is for adults who have not had treatment for H. pylori before.
Tanta, El-GharbiaAges 18 years+ - NCT06327477RecruitingPhase 1/Phase 2
A new type of radiation for newly diagnosed retroperitoneal sarcoma
This trial tests a new way of giving radiation called proton spatially fractionated radiotherapy (P-SFRT) combined with standard radiation for people with a type of sarcoma in the back of the belly. The goal is to see if this combination can treat the tumor more effectively.
Chicago, IllinoisAges 18 years+ - NCT02838602Recruiting
Carbon beam radiation vs standard radiation for resistant tumors
This study compares carbon beam radiation with standard radiation for tumors that are less likely to respond to usual radiation. It aims to see whether carbon beams can improve control of the cancer while keeping side effects manageable.
AmiensAges 18 years+ - NCT06518057RecruitingPhase 2
Sparing memory during brain radiation for leptomeningeal metastases
This trial tests a special type of radiation that avoids the memory center of the brain (the hippocampus) while treating cancer that has spread to the lining of the brain and spinal cord. It may help reduce side effects on thinking and memory for people with breast or lung cancer.
San Francisco, CaliforniaAges 18 years+ - NCT06719414Recruiting
Using a special MRI to predict rectal cancer response to pre-surgery therapy
This trial uses a special type of MRI scan (called amide proton transfer-weighted imaging) to look at your rectal cancer before and after chemotherapy and/or radiation. The goal is to see if the scan can predict whether the cancer has completely disappeared by the time of surgery, which could help guide future treatment decisions.
Guangzhou, GuangdongAges Any age - NCT06023641RecruitingPhase 2
Liposomal irinotecan for children with rhabdomyosarcoma
This trial tests a new way to treat rhabdomyosarcoma using a targeted drug (liposomal irinotecan) based on the tumor's genetic makeup and risk group. It aims to improve outcomes for children and young adults with intermediate or high-risk disease.
Palo Alto, CaliforniaAges Up to 22 years - NCT01696721Recruiting
Pediatric radiation therapy registry for children under 22
This study is a registry that collects information from children and teens who receive radiation therapy at participating hospitals. It helps researchers learn how radiation is used in pediatrics and may improve future care.
Palo Alto, CaliforniaAges Up to 21 years - NCT04416581RecruitingPhase 4
Compare two stomach-protecting medicines to prevent bleeding
This trial compares a potassium-competitive acid blocker to a proton pump inhibitor to help prevent stomach or intestinal bleeding in people at high risk who take blood-thinning medicines. It may help reduce dangerous GI bleeding while you stay on heart/stroke medicines.
AnyangAges 19 years+ - NCT05613452RecruitingPhase 2
Carbon ion radiation for peripheral lung cancer you can’t operate on
This trial tests whether carbon ion radiation (high-energy targeted radiation) can control peripheral non-small cell lung cancer in people who are medically unable to have surgery. It may help shrink or stop tumor growth while limiting harm to nearby organs.
Shanghai, Shanghai MunicipalityAges 18–80

Common questions
- Are there clinical trials for proton therapy?
- Yes. Clin2 currently lists 110 recruiting proton therapy studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a proton therapy trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a proton therapy trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
