Houston, TexasAges 18 years+ - NCT05037279RecruitingPhase 3
Testing BCG treatment for bladder cancer after full tumor removal
This trial studies a BCG-based bladder instillation in people with newly diagnosed, intermediate- or high-risk non-muscle invasive bladder cancer who have had their tumor fully removed. The goal is to see whether this treatment is safer and works better to lower the chance of the cancer coming back.
Vancouver, British ColumbiaAges 18 years+ - NCT05040360RecruitingPhase 2
Chemotherapy after surgery for high-risk pancreatic NET tumors
This Phase 2 trial studies whether giving chemotherapy after surgery can lower cancer recurrence risk in people with high-risk pancreatic neuroendocrine tumors (NETs). It may help you by testing an added treatment after the tumor has been removed.
Anchorage, AlaskaAges 18 years+ - NCT05042687Recruiting
Compare a breast imaging scan with MRI in high-risk women
This study compares two ways of imaging the breast—molecular breast imaging (a scan that uses a small radioactive tracer) and standard breast MRI—to better find or rule out breast cancer. You may join if you are considered high risk and already have a breast MRI planned, and you can do both tests close together.
Houston, TexasAges 18 years+ - NCT05055063RecruitingPhase 1
Belantamab for high-risk smoldering myeloma safety and early benefit
This Phase 1 trial tests belantamab mafodotin, a cancer medicine, in people with high-risk smoldering multiple myeloma to see how safe it is and whether it may shrink or control the disease. Because it’s an early-stage study, you would be closely monitored and treated with one main study drug.
Houston, TexasAges 18 years+ - NCT05080010RecruitingPhase 3
Extra chemo after eye removal for high-risk retinoblastoma
This Phase 3 study tests whether giving chemotherapy after the eye has been removed can lower the chance of retinoblastoma coming back for children with high-risk disease. You may be screened if your child had one eye affected and meet the staging and treatment history requirements.
Guangzhou, GuangdongAges Any age - NCT05086614RecruitingPhase 3
Thymosin-alpha 1 after surgery for high-risk colon cancer
This trial looks at whether thymosin-alpha 1, an immune-support treatment, can help prevent colon cancer from coming back after surgery. It targets people with high-risk stage II or III colon cancer who have had the tumor removed.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05095714Recruiting
Fast MRI for close monitoring of high-risk liver cancer
This trial studies a faster MRI scan to help track early liver cancer in people who have cirrhosis and are considered high risk. It may improve how often and how well doctors can look for changes without using longer imaging sessions.
BondyAges 18 years+ - NCT05116072RecruitingPhase 1/Phase 2
Islet cell transplant plus surgery for high fistula risk
This Phase 1/2 study tests whether adding an islet (insulin-producing cell) transplant at the time of pancreatic-region surgery is safe and helps prevent a serious surgical complication called a postoperative fistula. It is for people whose surgery is considered high risk for developing that complication.
LilleAges 18 years+ - NCT05123625Recruiting
Testing lymph node removal during bladder cancer surgery
This study looks at whether removing nearby lymph nodes during radical cystectomy (bladder removal) improves outcomes for people with high-risk non–muscle-invasive bladder cancer. It may help doctors choose the best surgical approach to reduce the chance of cancer coming back.
Nanjing, JiangsuAges 18–75 - NCT05124808Recruiting
Tight blood sugar targets in pregnant women with gestational diabetes
This study compares a tighter blood sugar goal versus a standard goal in pregnant people with gestational diabetes who are also overweight or obese. It may help find whether stricter blood sugar control improves pregnancy outcomes.
Birmingham, AlabamaAges 18–45 - NCT05135975RecruitingPhase 2
Cabozantinib maintenance to help stop pediatric cancer from growing
This trial studies cabozantinib given after standard treatment to try to keep high-risk pediatric solid tumors from coming back or getting worse. It is offered to children and young adults whose cancer has not fully disappeared but is not progressing at the start of this maintenance phase.
Birmingham, AlabamaAges 1.5 years–40 years - NCT05139095RecruitingPhase 2
Camrelizumab plus apatinib for high-risk pregnancy tumor
This Phase 2 trial studies whether combining camrelizumab (an immune medicine) with apatinib (a medicine that blocks blood-vessel growth) can improve treatment for women with high-risk gestational trophoblastic neoplasia (GTN) that is very high-risk, or has returned or resisted chemotherapy. It may help shrink the tumor and reduce the chance it comes back by using two different approaches together.
BeijingAges 18–60 - NCT05179889RecruitingPhase 2/Phase 3
Chemo after surgery for high-risk stage III colon cancer
This trial tests giving mFOLFIRINOX chemotherapy after curative surgery for people with high-risk stage III colon cancer. It aims to lower the chance that cancer comes back.
DaejeonAges 20–75 - NCT05197192RecruitingPhase 3
New treatment for high-risk CLL using two medicines plus chemo-free pills
This trial tests whether adding acalabrutinib to obinutuzumab plus venetoclax works better than the standard combo (obinutuzumab plus venetoclax) for people with untreated, high-risk CLL. It’s designed to see if the stronger mix can improve control of the leukemia with an acceptable safety profile.
