Recruiting studies
- NCT06008730RecruitingPhase 2

This trial tests if proton beam radiation therapy is safe and effective after surgery for non-small cell lung cancer that has spread to lymph nodes in the chest. It is for people who have already had chemotherapy before their surgery.
Atlanta, GeorgiaAges 18 years+ - NCT06826885Recruiting
Comparing two types of radiation for breast cancer
This trial is testing how well two different radiation techniques, IMPT and IMRT, work for treating breast cancer. It aims to see which one is safer and more effective, so you might benefit from a potentially better treatment approach.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06349486Recruiting
Comparing new treatments for H. pylori infection
This trial compares three different medication combinations to see which works best for treating H. pylori infection. If you have H. pylori and haven't been treated yet, you may be able to join.
Kaohsiung CityAges 18 years+ - NCT06630793Recruiting
Comparing types of radiation for anal cancer
This study compares standard radiation (IMRT) with a newer, more precise type (IMPT) both given alongside chemotherapy for anal cancer. It aims to see which is better at controlling cancer and reducing side effects.
Mumbai, MaharashtraAges 18–80 - NCT05151952Recruiting
Registry for people treated at a proton therapy center
This trial is a medical registry that collects information from people who receive proton therapy at a specific center. It helps researchers understand how proton treatment affects patients over time.
Pamplona, NavarreAges Any age - NCT06914999RecruitingEarly Phase 1
Comparing a new scan to standard scan during head and neck cancer radiation
This trial is testing whether a newer type of PET/CT scan (F-18 NaF) can better detect blood vessel problems caused by radiation therapy than the standard scan (F-18 FDG) in people with head and neck cancer. If successful, it could lead to better ways to prevent and manage these complications.
Atlanta, GeorgiaAges 18 years+ - NCT01684904Recruiting
Proton beam radiation for certain esophagus cancers
This trial studies whether proton therapy can better treat early-to-mid stage esophagus cancer while aiming to reduce side effects to nearby organs. Proton therapy uses a targeted type of radiation, and participants are also checked to be eligible for curative surgery.
Loma Linda, CaliforniaAges 18 years+ - NCT07215910RecruitingPhase 3
Testing vorasidenib with temozolomide after radiation for advanced brain cancer
This trial tests whether adding the targeted drug vorasidenib to standard chemotherapy (temozolomide) after radiation helps people with a specific type of advanced brain cancer called IDH-mutant astrocytoma. It is for patients who have not had previous treatments like chemotherapy or radiation and whose tumors have certain genetic features.
Duarte, CaliforniaAges 12 years+ - NCT07340515RecruitingPhase 3
Proton vs standard radiation for advanced nasopharyngeal cancer
This trial is testing whether a newer, more precise type of radiation (proton therapy) works better than standard radiation (IMRT) for people with advanced nasopharyngeal cancer. It also includes chemotherapy and immunotherapy to see if the combination can improve outcomes.
Jinan, ShandongAges 18–70 - NCT04376229Recruiting
Proton radiation registry for people treated at the center
This study keeps a record of patients who receive proton radiation therapy at a specific center. It may help doctors learn how this treatment is used and how patients do over time.
Washington D.C., District of ColumbiaAges 18–100 - NCT04671667RecruitingPhase 2
Pembrolizumab vs chemo-radiation after surgery for recurrent head/neck cancer
This trial tests whether pembrolizumab (an immunotherapy drug) works better than the usual chemo plus radiation after surgery for cancer that has come back in the head and neck area. It may help reduce cancer returning or spreading by using your immune system, but eligibility depends on how the cancer came back and your prior treatments.
Birmingham, AlabamaAges 18–79 - NCT01697371Recruiting
Proton beam radiation for liver metastases
This trial tests whether proton beam therapy can control cancer that has spread to the liver. It may help shrink liver tumors or slow their growth while aiming to reduce harm to nearby organs.
Loma Linda, CaliforniaAges 18 years+ - NCT06500481RecruitingPhase 3
Proton vs standard radiation for cancer spread to brain/spine lining
This trial compares a newer type of radiation (proton therapy) to standard radiation for people whose breast or lung cancer has spread to the lining of the brain and spinal cord. It aims to see if proton therapy can better control the disease while causing fewer side effects.
Phoenix, ArizonaAges 18 years+ - NCT06846450RecruitingPhase 3
Comparing radiation types for nasopharyngeal cancer
This trial compares two types of radiation therapy (IMRT or IMPT plus CIRT) to see which works better for patients with nasopharyngeal cancer that hasn't spread. It's for people who have not had radiation to the head or neck before.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07532824RecruitingPhase 1/Phase 2
Proton Radiation and Stem Cell Transplant for High-Risk Blood Cancers
This trial tests a new type of radiation therapy (proton-based) combined with a stem cell transplant from a donor to treat advanced forms of acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). The goal is to improve survival in patients with aggressive or hard-to-treat disease.
PragueAges 18–65 - NCT03180268RecruitingPhase 3
Watch or radiate after surgery for grade II meningioma
This trial studies whether people with a grade II meningioma that has been completely removed by surgery should be monitored only or treated with radiation. It may help reduce the risk of the tumor coming back while balancing radiation side effects.
Birmingham, AlabamaAges 18 years+ - NCT06883604Recruiting
Proton therapy for early-stage Hodgkin lymphoma
This trial tests if proton beam radiation can effectively treat Hodgkin lymphoma while reducing side effects. It is for people with early-stage disease who have already completed chemotherapy and need radiation.
GothenburgAges 18–60 - NCT05406856Recruiting
Adaptive proton therapy for cervical cancer with chemo
This trial tests whether an “adaptive” type of radiation planning using proton therapy and MRI-guided brachytherapy can improve treatment for people with cervical cancer. It aims to deliver curative treatment more precisely while still combining it with chemotherapy (cisplatin) when appropriate.
LeidenAges 18 years+ - NCT04695782RecruitingPhase 2
Proton radiation for recurrent rectal cancer in the pelvis
This trial studies “pencil beam” proton radiation for rectal cancer that has come back in the pelvis after you already had radiation. It aims to control the recurrence while trying to limit harm to nearby organs.
AarhusAges 18 years+ - NCT01492972RecruitingPhase 3
Lighter radiation, with or without hormone suppression
This Phase 3 trial tests whether giving a smaller amount of radiation (“hypo-fractionated” means fewer, larger sessions) can work as well as standard approaches for intermediate-risk prostate cancer. It also compares adding hormone therapy (“androgen suppression”) to radiation versus using radiation alone.
Scottsdale, ArizonaAges 18 years+ - NCT01766297RecruitingPhase 2
Proton radiation after lumpectomy for early breast cancer
This trial studies a type of radiation made with protons to treat only part of the breast after surgery (lumpectomy) for early-stage breast cancer. It may help control the cancer while aiming to reduce radiation to surrounding tissues.
Scottsdale, ArizonaAges 50 years+ - NCT05758688RecruitingPhase 2
Proton radiation after surgery for uterine or cervical cancer
This trial studies whether proton beam radiation after surgery can better treat certain uterine (endometrial) or cervix (cervical) cancers. It may help by targeting the pelvic area while limiting radiation to nearby organs.
Voorhees Township, New JerseyAges 18 years+ - NCT03750513RecruitingPhase 1
Tested improved radiation targeting for children with ependymoma
This early-phase study tests a more precisely targeted type of radiation for children with ependymoma, aiming to treat the brain tumor more accurately. It may help reduce how much healthy tissue gets radiation, and researchers are checking safety and best dosing.
Boston, MassachusettsAges Up to 22 years - NCT04066465Recruiting
Testing how proton therapy affects thinking in young people
This study looks at how proton radiation therapy may affect thinking, learning, and brain function in children and teens with a primary brain tumor. It uses repeated short brain/learning tests to track possible changes over time.
