Boston, MassachusettsAges 18 years+ - NCT06827782Enrolling by invitationPhase 1
Cord blood CAR-NK cells for relapsed CNS lymphoma
This trial tests a new treatment using specially engineered immune cells from cord blood to target and kill cancer cells in the brain or spine. It is for people whose central nervous system lymphoma has not responded to or has returned after previous treatments.
Hangzhou, ZhejiangAges 18–75 - 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+ - NCT06834126RecruitingPhase 1
Papaverine with radiation for advanced rectal cancer
This trial tests if adding papaverine (a drug) to radiation therapy can help people with locally advanced rectal cancer avoid surgery and keep their rectum. It is for patients who have already had chemotherapy and want a non-surgical approach.
Duarte, CaliforniaAges 18 years+ - NCT06834321RecruitingPhase 2
Homoharringtonine with hormone therapy before prostate surgery
This trial tests a new combination of a chemotherapy drug (homoharringtonine) and hormone therapy (androgen deprivation) given before surgery to shrink prostate cancer that has spread a little or is advanced. The goal is to see if this approach can help control the cancer better before the prostate is removed.
Nanjing, JiangsuAges 18–85 - 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.
Houston, TexasAges 18 years+ - NCT06826924Recruiting
Fasting or ketones for prostate cancer
This trial tests whether a 7-day water-only fast or taking ketone supplements can help treat prostate cancer. You would have a biopsy before and after to see how the tumor responds.
Baltimore, MarylandAges 18 years+ - NCT06828614Enrolling by invitation
Barriers to exercise in breast cancer patients
This study looks at the challenges women with breast cancer face when trying to exercise before, during, and after chemotherapy. It aims to understand what gets in the way so that better support can be offered.
ValenciaAges 18–65 - NCT06826768RecruitingPhase 1
Study of REGN5678 plus cemiplimab for advanced prostate cancer
This trial tests a combination of two drugs (REGN5678 and cemiplimab) for men with metastatic castration-resistant prostate cancer that has progressed after at least two prior treatments. The goal is to see if this new combination can help shrink the cancer or slow its growth.
Houston, TexasAges 18 years+ - NCT06835803RecruitingPhase 2
Intensified radiation for older adults with glioblastoma
This trial tests whether a more focused, stronger dose of radiation can improve outcomes for people 65 and older with newly diagnosed glioblastoma. It compares this approach to standard radiation to see if it's safe and effective.
Boston, MassachusettsAges 65 years+ - NCT06829043Enrolling by invitation
PET scan for uncertain thyroid nodules
This study uses a special PET scan (18F-FDG PET/CT) to get a clearer picture of thyroid nodules with uncertain biopsy results. The goal is to help doctors decide whether surgery is needed.
Bologna, ItalyAges 18 years+ - NCT06826014Recruiting
Cancer prevention registry and biorepository study
This study creates a registry of people who have had certain cancer screenings or have conditions linked to cancer risk. Participants donate blood, urine, and cheek swab samples and allow their health records to be followed for five years to help future cancer research.
Bryan, TexasAges 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+ - NCT06829836Enrolling by invitation
Can breathing exercises improve your mental health?
This trial tests whether breathing exercises can help reduce symptoms of depression, anxiety, and stress. You may qualify if you are between 18 and 50, have mild to moderate symptoms, and are willing to avoid high-intensity exercise and structured breathing for a month.
Greeley, ColoradoAges 18–50 - NCT06831669Recruiting
Predicting rectal cancer treatment response and side effects

Mosunetuzumab for older DLBCL patients with residual ctDNA
This trial tests whether adding a targeted immunotherapy drug called mosunetuzumab after standard chemotherapy can help older adults with DLBCL who still have tiny traces of cancer DNA in their blood. If you qualify, the goal is to reduce the chance of the cancer coming back.
Rochester, New YorkAges 70 years+ - NCT06828588RecruitingEarly Phase 1
A new imaging test for people on HER2 cancer therapy
This study tests a new imaging drug called [68Ga]Ga-ABY-025 to see how well it shows HER2-positive tumors in people who are about to start or have just started HER2-targeted cancer therapy. It may help doctors see if the treatment is working.
