How past eye-cancer treatment affects survivors’ well-being
This study looks at how different treatments for one affected eye retinoblastoma may affect survivors’ emotional and social functioning. It may help doctors understand which treatment approaches are linked with better day-to-day well-being over time.
New York, New YorkAges 8–17 - NCT05481697Recruiting
Track weight changes and check with a cancer blood test
This study looks at whether closely tracking small, unplanned weight loss—along with a one-time blood test (Galleri)—can help find cancer earlier. It may help people who notice changes in weight without knowing why.
Cleveland, OhioAges 40–80 - NCT03522064RecruitingPhase 2
HRD-positive advanced prostate cancer trial with androgen therapy and chemo
This Phase 2 study tests whether blocking male hormones (androgen therapy) plus the chemotherapy drug carboplatin can shrink advanced prostate cancer in men with specific DNA repair problems. It is for cases where prostate-specific antigen (PSA) is rising even though testosterone is already kept very low.
Sydney, New South WalesAges 18 years+ - NCT03342625Recruiting
Focused ultrasound treatment for certain breast tumors
This trial tests whether high-intensity focused ultrasound (a targeted heat treatment) can treat some types of breast tumors and potentially reduce the need for more invasive surgery. It may help people who have specific tumor features and who are able to safely undergo MRI and the required positioning.
BordeauxAges 18 years+ - NCT04823897RecruitingPhase 1
Testing CCI-001 alone and with chemo for recurrent solid tumors
This early study tests whether CCI-001 can be given safely and may help shrink or control recurrent or metastatic (advanced) solid cancers. It checks the right dose first, then studies CCI-001 with standard chemotherapy in certain cancer types.
Edmonton, AlbertaAges 18 years+ - NCT02445222RecruitingPhase 3
Follow-up study for people treated with CAR-T therapy
This study checks how people do over the long term after receiving CAR-T, an advanced immune treatment. It may help doctors understand long-term safety and benefits, and what to expect after treatment.
Phoenix, ArizonaAges birth–100 years - NCT02421380Recruiting
Tests how repeatable a special MRI scan is for tumors
This study checks whether a specialized MRI using injected “hyperpolarized pyruvate” gives consistent tumor images when repeated. It may help future patients by improving how reliably this scan can measure tumors.
Montvale, New JerseyAges 21–90 - NCT02657785RecruitingPhase 2/Phase 3
Treating newly diagnosed brain lymphoma with added medicines into CSF
This trial studies a treatment plan for people with newly diagnosed non-Hodgkin lymphoma that has spread to the brain and covering tissues (meninges). It combines medicines given through the bloodstream with immunotherapy placed into the fluid around the brain (CSF) to improve control of the lymphoma.
Beijing, Beijing MunicipalityAges 18–75 - NCT05623319RecruitingPhase 2
Pembrolizumab plus olaparib for extensive small cell lung cancer
This Phase 2 study tests whether combining pembrolizumab and olaparib can improve outcomes in people with extensive-stage small cell lung cancer. It mainly aims to shrink tumors and help control the cancer for longer.
Meldola, Forlì CesenaAges 18 years+ - NCT02559752Recruiting
Computer brain testing during proton radiation for childhood tumors
This trial studies how children’s thinking and learning skills change while they receive proton beam radiation for a brain/spinal cord tumor. It uses computer-based cognitive tests to better understand brain effects during treatment, which may help future care.
St Louis, MissouriAges 4–21 - NCT02559804Recruiting
Study of nerve tumors in children affecting the spine canal
This study follows children and teens with certain nerve-cell tumors (like neuroblastoma) that involve the spinal canal. It collects information on how these tumors behave and how treatments and outcomes may differ, aiming to improve care over the long term.
GenovaAges Up to 18 years - NCT05530057RecruitingPhase 2
Eribulin plus or minus trastuzumab for HER2-positive breast cancer
This trial tests whether adding trastuzumab to eribulin improves outcomes for people with HER2-positive breast cancer that has come back or spread. It’s meant for patients whose cancer has progressed after prior HER2 and chemotherapy treatments.
SeoulAges 18 years+ - NCT05354570RecruitingPhase 2
Radiation for thymic cancer that has spread to lung lining
This Phase 2 study tests a precise type of chest radiation that targets cancer in the lung lining (pleura) while trying to protect healthy lungs and organs. It may help people with thymic cancer that has spread to the pleura, including cases that return after prior treatment.
Basking Ridge, New JerseyAges 18–79 - NCT05381597RecruitingPhase 2/Phase 3
Skin cream treatment for small early non-melanoma skin cancers
This study tests whether 5-fluorouracil and calcipotriene (medicines used on the skin) can treat certain small, early skin cancers or pre-cancers without surgery. It’s for specific types and locations of lesions and aims to see how well the treatment works and how safe it is.
Boston, MassachusettsAges 18 years+ - NCT05406999RecruitingPhase 2
Intense hormone treatment before prostate surgery for high-risk cancer
This Phase 2 trial studies giving strong hormone-based treatment before prostate surgery to shrink and control high-risk, locally advanced prostate cancer. It may help improve surgical success and reduce cancer spread risk, but it requires careful health checks and prior-treatment limits.
Nanjing, JiangsuAges 18–80 - NCT05547321RecruitingPhase 1
New cancer drug plus immunotherapy for advanced solid tumors
This early-phase trial studies OMTX705, given by itself or with an anti–PD-1 immune therapy, in people with advanced solid cancers that can’t be cured or that stopped responding to standard treatments. It aims to check safety and see whether the treatment can shrink tumors or control disease.
Boston, MassachusettsAges 18 years+ - NCT05263960RecruitingPhase 1/Phase 2
CM350 drug study for advanced solid tumors
This trial tests CM350 in people with advanced solid cancers that are hard to treat with standard options. It may help by finding a safe dose and whether the drug can work against these cancers.
Chengdu, SichuanAges 18–75 - NCT05360277RecruitingPhase 2
Maintenance immunotherapy and chemo after surgery for metastatic colon cancer
This Phase 2 trial studies tislelizumab plus capecitabine given after surgery to help prevent metastatic colorectal cancer from coming back. It may be an option if you recently had surgery that removed visible disease and you have good overall health.
Guangzhou, GuangdongAges 18–80 - NCT05193240Recruiting
Swallowing test to predict vocal cord paralysis after lung surgery
This study checks whether a simple swallowing test can forecast vocal cord paralysis after lung surgery, compared with a camera exam of the throat. If predictions are accurate, it may help doctors prevent or plan treatment for swallowing and voice problems.
RouenAges 18 years+ - NCT04969354RecruitingPhase 1
CAIX-targeted CAR-T therapy for advanced kidney cancer
This early-phase study tests a lab-made immune treatment (CAIX-targeted CAR-T cells) for advanced kidney cancer that has not gone away with standard targeted therapy or immunotherapy. If eligible, the goal is to see if the treatment can safely shrink the cancer and improve outcomes.
Xuzhou, JiangsuAges 18–70 - NCT04920968RecruitingPhase 2
Obinutuzumab versus rituximab for newly diagnosed ALL
This Phase 2 study compares two antibody treatments—obinutuzumab and rituximab—for newly diagnosed acute lymphoblastic leukemia (ALL) that has the CD20 marker. It aims to see which treatment works better and is safe for people whose leukemia cells have CD20.
BialystokAges 18 years+ - NCT05521698RecruitingPhase 1
Bicalutamide study for early bladder cancer in men
This trial tests whether bicalutamide can help men with non-muscle invasive bladder cancer (an early form that hasn’t spread into muscle). It is a Phase 1 study, meaning the main goal is to see how safe it is and learn how it behaves in the body for this cancer type.
Tucson, ArizonaAges 18 years+ - NCT05053113Recruiting
Text-and-Fitbit support for less-active women to move more
This trial studies a peer-based (partner) approach using text messages and a Fitbit app to help inactive women increase their physical activity. It may help you find easier, ongoing motivation and support to reach recommended activity levels.
