Proton vs photon radiation for brain tumors
This study compares two types of radiation therapy for adults with primary brain tumors that have a good outlook (expected survival longer than 5 years). You will receive either standard photon radiation or the more targeted proton radiation, to see if one works better or causes fewer side effects.

How bowel prep affects gut bacteria recovery
This study looks at how the bowel preparation medicine (PEG) used before a colonoscopy affects the bacteria living in your gut and how well they recover afterward. Healthy volunteers will take the bowel prep and provide stool samples to help researchers understand this process.

Jacksonville, FloridaAges 18 years+ - NCT06831773Recruiting
Carbon ion radiation for high-grade brain tumors
This trial tests a precise type of radiation called carbon ion radiotherapy for people with aggressive brain tumors (high-grade gliomas). It aims to see if this treatment is safe and effective for patients who have not had radiation to the head before.
Wuwei, GansuAges 14–80 - NCT06831903Recruiting
Radiation therapy for head and neck cancer
This trial is studying a type of radiation therapy for head and neck cancer. It aims to find the best way to deliver radiation to help treat the cancer effectively.
Würzburg, BavariaAges 18 years+ - NCT06831955RecruitingPhase 2
Lifestyle program to boost chemo before breast cancer surgery
This trial tests whether a structured lifestyle program (diet and exercise) can make standard chemotherapy before surgery work better for triple-negative breast cancer. It looks at how the program affects your body’s response to treatment and your overall health.
AntwerpAges 18 years+ - NCT06831981Recruiting
Heat therapy with chemo and radiation for rectal cancer
This trial tests if adding heat therapy (hyperthermia) to standard chemotherapy and radiation helps treat rectal cancer that has high-risk features. Heat therapy is thought to make cancer cells more sensitive to treatment.
Tübingen, Baden-WurttembergAges 18 years+ - NCT06832228Recruiting
Study of Pomalidomide with Rituximab and Immunotherapy for DLBCL
This trial tests a combination of three drugs (pomalidomide, rituximab, and an immunotherapy called anti-PD-1) for people with diffuse large B-cell lymphoma that has not responded or has come back after two prior treatments. The goal is to see if this combination can help control the lymphoma.
Hangzhou, ZhejiangAges 18–80 - NCT06832384Recruiting
Intensive physiotherapy for children with posterior fossa tumors
This trial tests if intensive physical therapy helps children recover after surgery for a brain tumor at the back of the head. It is designed for kids and young adults up to age 25.
Brindisi, BrindisiAges birth–25 years - NCT06833073RecruitingPhase 2
Study of an mRNA vaccine and BCG for bladder cancer
This trial tests an experimental mRNA vaccine (V940) combined with BCG therapy for people with high-risk non-muscle invasive bladder cancer that hasn't spread. It aims to see if the vaccine can help the immune system better fight the cancer.
Bakersfield, CaliforniaAges 18 years+ - NCT06833255Recruiting
Support Program for Black Women Breast Cancer Survivors
This program pairs Black women who have completed breast cancer treatment with support to help them transition into survivorship. It offers mentorship based on how recently you finished treatment, with priority for those who had limited support or who identify as African American.
Buffalo, New YorkAges 18 years+ - NCT06833229Recruiting
Can a PET scan predict if immunotherapy is working?
This study uses a special PET-CT scan early in your treatment to see if immunotherapy (with or without chemotherapy) is working against your advanced lung cancer. The goal is to find out faster if the treatment is helping.
NiceAges 18 years+ - NCT06833502RecruitingPhase 2
Screening for breast cancer spread after chemo and surgery
This trial aims to find out if doing special scans to check for breast cancer spread to organs (not just lymph nodes) is helpful in certain patients. The study looks at people with breast cancer that had already spread to lymph nodes and did not completely go away with chemotherapy and surgery.
Tampa, FloridaAges 18 years+ - NCT06833632Recruiting
Studying cancer cells in the blood and air spaces for early lung cancer
This study looks for cancer cells that travel through the blood or spread through air spaces in the lungs of people with early-stage lung cancer. The goal is to understand how these cells affect the disease, and it may help doctors plan better treatment in the future.
Bologna, Emilia-RomagnaAges 18 years+ - NCT06833853Recruiting
Blood test study for women with advanced breast cancer
This study looks at a blood test that measures certain markers on cancer cells (CTCs) and genetic material in the blood (cfDNA/RNA) in women with metastatic breast cancer. It aims to better understand the cancer and guide treatment decisions.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06833866RecruitingPhase 1
Testing a natural compound with chemo for advanced colorectal cancer
This trial combines a natural substance called hydroxytyrosol (HT) with standard chemotherapy (5-FU and possibly other drugs) for people with advanced or metastatic colorectal cancer that hasn't been treated yet. The goal is to see if adding HT makes the treatment work better.
