Delafield, WisconsinAges 2 years+ - NCT04807140RecruitingPhase 2
Study of toripalimab before surgery for head and neck cancer
This trial tests toripalimab (an immunotherapy) given before surgery for untreated head and neck squamous cell carcinoma, either alone or with chemotherapy. The goal is to shrink or control the cancer earlier and see if it improves outcomes for people who plan curative surgery.
Guangzhou, GuangdongAges 18–80 - NCT04807881RecruitingPhase 1
Study of keynatinib for certain hard-to-treat lymphomas
This Phase 1 trial tests keynatinib, a new medicine, in people with specific types of lymphoma that have returned or not responded to earlier treatment. It aims to find a safe dose and see whether it can shrink tumors in the brain or elsewhere in the body, depending on the group.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04808323RecruitingPhase 1
MRI-guided radiation to help preserve organs in rectal cancer
This Phase 1 study tests a radiation treatment approach guided by MRI scans to help keep nearby organs functioning while treating rectal cancer. It is designed to find a safe, effective way to target the tumor and adjust treatment during the course of therapy.
Milwaukee, WisconsinAges 18 years+ - NCT04809025Recruiting
Testing biopsy samples vs surgery samples for stomach cancer testing
This study compares two ways of getting stomach cancer tissue: a camera-guided biopsy and a tissue sample taken during planned stomach surgery. The goal is to see which sample better supports molecular (gene-based) testing to guide diagnosis.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04809324Recruiting
Testing how best to check surgical margins in oral cancer
This trial compares two ways of checking whether all oral cancer tissue was removed during surgery by looking at the tissue edges. It may help surgeons choose the safest approach to reduce the chance of cancer coming back.
Mumbai, MaharashtraAges 18–100 - NCT04811703RecruitingPhase 1
Testing aerosol chemotherapy through the belly for advanced ovarian cancer
This Phase 1 study tests a new way to deliver chemotherapy inside the abdomen (belly) using a pressurized aerosol during a procedure, along with standard blood (IV) chemotherapy. It may help people with advanced ovarian cancer whose tumors have not progressed but are not removable with surgery yet.
LilleAges 18–75 - NCT04811794Recruiting
Study of young cancer survivors followed at a Swiss hospital
This study looks at the experiences and health of people who finished childhood cancer treatment and are (or were) followed by Kantonsspital Aarau. It mainly involves sharing and reviewing medical information to understand survivorship after cancer.
AarauAges Any age - NCT04812912Recruiting
Study sexual and reproductive effects in early colon cancer
This study looks at how early-onset colorectal cancer treatment affects reproductive and sexual health over time. It asks eligible people to complete questionnaires so researchers can understand and possibly improve care during and after treatment.
Basking Ridge, New JerseyAges 18–50 - NCT04814095Recruiting
Testing personalized cancer treatment options for rare cancers
This study collects evidence on personalized (“targeted”) cancer treatments for adults with rare cancers or rare tumor changes. If you may qualify, it may help make these treatments more widely available in the future by studying how well they work and how patients feel.
Vancouver, British ColumbiaAges 18 years+ - NCT04813705RecruitingPhase 2
PET/CT-guided lower-dose radiation for nasopharyngeal cancer
This Phase 2 study tests whether using a special scan (PET/CT) to guide radiation can safely reduce the radiation dose for people with nasopharyngeal cancer. It may help lessen side effects while still treating the cancer effectively.
Taizhou, ZhejiangAges 18–80 - NCT04815356RecruitingPhase 1
T cells designed to attack a blood cancer called hairy cell leukemia
This early-stage (Phase 1) study tests a new type of treatment made from your T cells (immune cells) that are programmed to find and kill cancer cells with a specific marker (CD22). It’s designed for people with hairy cell leukemia that has come back or didn’t respond to prior treatments, and it aims to see safety and how well the approach works.
Bethesda, MarylandAges 18 years+ - NCT04815525Recruiting
Long-term bowel cancer risk after colonoscopy in Hong Kong
This study follows people in Hong Kong over time to learn how the future risk of advanced colon growth changes after they have a colonoscopy. It may help doctors better predict who needs closer follow-up in the years after a colonoscopy.
Shatin, New TerritoriesAges Any age - NCT04814407Recruiting
Test blood and other markers to detect early lung cancer
This study looks for new “epigenetic” signals in blood (signals about how genes are turned on/off) to help detect lung cancer early. You might be able to join if you are being evaluated for possible lung cancer or have small, unclear spots on a lung CT scan.
TaipeiAges 20 years+ - NCT04816292Recruiting
Compare removal of colon polyps with hot vs cold snare
This study compares two ways doctors remove certain colon polyps during colonoscopy: “hot snare” versus “cold snare.” It’s looking at whether one method removes polyps better and with fewer problems for people with polyps that are 10–15 mm.
München, BavariaAges 18–80 - NCT04817163Recruiting
Testing a CBT-I sleep program in cancer clinics
This trial tests whether a structured sleep program called CBT-I can help people with non-metastatic cancer sleep better. It may help by teaching practical, evidence-based steps for insomnia in a cancer-clinic setting.
QuébecAges 18 years+ - NCT04817566Recruiting
Brain stimulation and training for thinking problems after breast cancer
This study tests whether brain stimulation plus cognitive training can improve thinking and memory problems in women after chemotherapy for breast cancer. It may help if you still feel “foggy” or have trouble concentrating months after treatment.
GreifswaldAges 18–65 - NCT04817956RecruitingPhase 2
Precision-medicine treatment for advanced cancer in Norway
This Phase 2 trial tries to match people with advanced cancer to targeted treatments based on their tumor’s genetic results. It may help if standard cancer treatments are no longer working or aren’t available, and if a “target” in the tumor suggests a therapy that could work.
ÅlesundAges 16 years+ - NCT04819542Recruiting
Compression bandages to prevent fluid pockets after breast surgery
This study tests whether compression bandages can reduce “lymphoceles,” which are fluid collections that can happen after mastectomy-type breast surgery. If you’re having this surgery, the trial may help prevent complications and improve recovery.
ToulouseAges 18 years+ - NCT04823403RecruitingPhase 1
Targeted liver delivery of immunotherapy for advanced liver cancer
This early-phase study tests how well giving ipilimumab directly into the liver (via an artery) and nivolumab through a vein works for advanced hepatocellular carcinoma (liver cancer). It is for people whose cancer cannot be removed with surgery or treated with a transplant, especially after standard treatment failed or wasn’t tolerated.
VillejuifAges 18 years+ - NCT04821843RecruitingPhase 3
Study before-surgery treatments for esophageal cancer
This Phase 3 trial compares different “treatments before surgery” for people with esophageal (or esophagus-to-stomach) cancer. It aims to see which approach works better to control the cancer and improve outcomes after surgery.
BeijingAges 18 years+ - NCT04821778RecruitingPhase 3
Testing chemoradiotherapy for esophageal and stomach junction cancer
This Phase 3 study tests a cancer treatment plan that combines chemotherapy and radiation for people with esophageal or esophagus-stomach junction cancer. It aims to see whether this approach works better than standard care for cancers at stages I to IVA.
Anyang, HenanAges 18 years+ - NCT04822077Recruiting
Proton beam treatment for thymus tumors
This trial studies proton radiotherapy (a type of radiation) for cancers of the thymus, like thymoma or thymic carcinoma. It may help improve tumor control while limiting radiation exposure to nearby organs.
Umeå, NorrlandAges 18 years+ - NCT04823923Recruiting
How kidney failure affects drug levels in metastatic kidney cancer
This study looks at how chronic kidney failure changes the amount of certain cancer medicines in the blood. It involves people with metastatic clear cell kidney cancer who take pazopanib or cabozantinib, and compares drug levels in different kidney function groups.
