ShanghaiAges 18–70 - NCT07332975Recruiting
Blood test for tumor DNA in early triple-negative breast cancer
This study is for people with early-stage triple-negative breast cancer (TNBC) that has not been treated yet. Researchers want to see if tracking tumor DNA in your blood can help guide treatment decisions. You would receive standard chemotherapy and surgery, plus give blood samples.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT07300449RecruitingPhase 2
Predicting chemo response in children with hepatoblastoma
This trial tests a new way to see if chemotherapy will work for children with hepatoblastoma, a type of liver cancer. It uses a blood test (ctDNA 5hmc) to help predict treatment success and monitor if the cancer comes back.
Guangzhou, GuangdongAges Up to 18 years - NCT06382103Recruiting
Liver cancer study after surgery or pre-surgery therapy
This study looks at genetic markers in the blood of people with liver cancer who are having surgery, either right away or after some treatment first. It aims to find out why some patients do better, which could help personalize care.
ShanghaiAges Any age - NCT07264673RecruitingPhase 2
Cemiplimab plus OSE2101 as maintenance after chemo-immunotherapy for lung cancer
This trial tests a combination of two drugs (cemiplimab and OSE2101) as ongoing treatment after initial chemo-immunotherapy for advanced lung cancer. It is for patients whose tumor DNA is still detectable in the blood, and who carry a specific immune marker called HLA-A2.
Roma, RMAges 18–99 - NCT06903325Recruiting
Monitoring DNA markers in blood to predict colorectal cancer return after surgery
This study tests if a simple blood test can detect early signs of colorectal cancer coming back after surgery to remove cancer spread in the abdomen. It may help patients avoid unnecessary treatments and catch recurrence sooner.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06902012RecruitingPhase 1/Phase 2
Second infusion of CAR-T based on ctDNA for large B-cell lymphoma
This trial tests whether a second infusion of a CAR-T cell therapy called Axi-cel, given early based on a blood test (ctDNA), can help people with relapsed or hard-to-treat large B-cell lymphoma. If you had a partial response or your ctDNA stayed positive after the first dose, you may be eligible.
Guangzhou, GuangdongAges 18 years+ - NCT07227636RecruitingPhase 2
Immunotherapy for ctDNA-positive colorectal cancer after surgery
This trial tests two immunotherapy drugs, botensilimab and balstilimab, for people with colorectal cancer who have had surgery and chemotherapy but still have detectable cancer DNA in their blood. The goal is to see if these drugs can help clear the remaining cancer cells.
Basking Ridge, New JerseyAges 18 years+ - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
Phoenix, ArizonaAges 18 years+ - NCT07211178Recruiting
Tracking cancer DNA in blood to detect early return of breast cancer
This study tracks tiny traces of cancer DNA in the blood over time to see if it can find early signs of breast cancer coming back. It looks at different types of breast cancer and at different points in a patient's treatment journey.
Birmingham, AlabamaAges 18–99 - NCT07188025RecruitingPhase 3
Cancer DNA test to guide chemo after rectal cancer surgery
This trial tests whether checking for tumor DNA in your blood after surgery can help decide if you need additional chemotherapy. If the test finds cancer DNA, you may get chemo to lower the risk of the cancer coming back.
's-HertogenboschAges 18 years+ - NCT07176962Recruiting
Blood test for early detection of bile duct cancer
This study is testing a new blood test that looks for signs of DNA changes linked to biliary tract cancer. It aims to see if the test can find these cancers early. If you have biliary tract cancer or a high suspicion of it, you may be able to help.
