Basking Ridge, New JerseyAges 18 years+ - NCT04563507RecruitingPhase 2
Immunotherapy plus hormone therapy for metastatic ER-positive breast cancer
This Phase 2 study tests a combination of immune-based treatments along with hormone (endocrine) therapy to slow or shrink advanced, hormone-receptor positive, HER2-negative breast cancer. You may be a candidate if your cancer has progressed after standard hormone-blocking medicines and you can start treatment with CDK4/6 medicine plus an aromatase inhibitor.
New York, New YorkAges 18–90 - NCT02297217RecruitingPhase 2
Chemoradiation for advanced esophagus cancer that can’t be cured
This trial studies whether a combination of chemotherapy and radiation can help people with advanced esophageal cancer who cannot have curative treatment. It focuses on people who are having swallowing trouble and may be able to start treatment soon.
Calgary, AlbertaAges 18 years+ - NCT05479409RecruitingPhase 2
Radiation before surgery for advanced breast cancer
This trial tests whether giving radiation therapy before surgery helps people with locally advanced breast cancer that hasn't been removed with chemotherapy. It may offer a new option for those who cannot have surgery right away.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05500612Recruiting
MRI oxygen scan study for glioblastoma during radiation treatment
This study uses special MRI scans to measure oxygen levels in and around glioblastoma before and during radiation treatment. It may help researchers understand how oxygen affects treatment response and timing.
St Leonards, New South WalesAges 18 years+ - NCT05427136Recruiting
Study early lung problems after childhood cancer treatment
This study looks for early lung (breathing) problems in children after certain cancer treatments, using lung tests and sometimes MRI scans. It may help doctors spot breathing complications earlier and guide better care.
BaselAges 4–22 - NCT05382338RecruitingPhase 3
Sodium thiosulfate to protect hearing in medulloblastoma
This Phase 3 study tests whether adding sodium thiosulfate during treatment for newly diagnosed medulloblastoma can reduce the risk of hearing loss. It is designed for children and teens whose cancer meets specific low-risk or average-risk tumor and lab features.
Birmingham, AlabamaAges 4–21 - NCT05384496RecruitingPhase 2
Axitinib and nivolumab for advanced mucosal melanoma
This trial studies how well two medicines—axitinib and nivolumab—work for people with advanced melanoma that starts in moist “mucosal” areas (like the mouth, nose, throat, or bowel). It may help shrink tumors and control the disease by boosting the immune system and targeting tumor growth.
Harrison, New YorkAges 18 years+ - NCT05388773RecruitingPhase 2
Surgery then lower-dose radiation for p16+ throat cancer
This Phase 2 study tests whether removing the tumor through the mouth, followed by a reduced course of radiation, can control HPV-related (p16+) oropharynx throat cancer. It may help reduce treatment intensity after surgery, while still aiming to keep the cancer from coming back.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05327686RecruitingPhase 2
Adding focused radiation to immunotherapy for kidney cancer
This Phase 2 trial studies whether adding focused, high-precision radiation to immunotherapy helps people with advanced kidney cancer (that cannot be removed by surgery or has spread). It aims to improve cancer control by combining two treatment approaches.
Birmingham, AlabamaAges 18 years+ - NCT05317221Recruiting
Developing breast cancer tissue models for research
This trial builds lab “models” (called organoids) from breast cancer tissue to help researchers study different breast cancer types. You may be able to help by providing consent and meeting the study’s basic cancer and treatment history requirements.
MaastrichtAges 18 years+ - NCT05346848RecruitingPhase 2
Darolutamide plus radiation for intermediate-risk prostate cancer
This trial tests whether adding darolutamide to standard radiation can better control intermediate-risk prostate cancer. It includes men whose cancer has spread nowhere else and who are newly diagnosed with “unfavorable intermediate risk” or progress to that risk group.
AvignonAges 18 years+ - NCT05328505Recruiting
Imaging-guided radiation for prostate cancer that came back
This trial tests whether a special scan (PSMA PET) can help doctors aim and adjust radiation more precisely when prostate cancer returns after surgery. It may help by increasing dose to areas that look involved while lowering dose to uninvolved pelvic areas.
London, OntarioAges 18 years+ - NCT05304585RecruitingPhase 3
Chemo for children with early, low-risk fusion-negative rhabdomyosarcoma
This Phase 3 study tests a chemotherapy plan for children and teens with newly diagnosed, very low-risk or low-risk rhabdomyosarcoma that does not have certain gene fusions (FOXO1 fusion negative). The goal is to see if this treatment can work well while limiting side effects by matching therapy to early-stage risk.
Birmingham, AlabamaAges Up to 21 years - NCT05258422Enrolling by invitationPhase 2
Radiation ablation for recurring heart rhythm tachycardia
This study tests a targeted form of radiation therapy to stop a dangerous, repeat heart rhythm called ventricular tachycardia. It’s for people whose rhythm keeps coming back even after standard treatments like antiarrhythmic medications and prior heart procedure studies.
Montreal, QuebecAges 18 years+ - NCT05268614RecruitingPhase 2
Risk-based reduced chemo and radiation for HPV throat cancer
This trial tests whether using a lower intensity (reduced) chemo-radiation plan can work for some people with HPV-related oropharyngeal (throat) cancer without losing effectiveness. It may help reduce side effects while still controlling the cancer.
Gainesville, FloridaAges 18 years+ - NCT05307939RecruitingPhase 2
Using tumor DNA tests to time treatment for HPV throat cancer
