Blood test to monitor targeted therapy response in advanced lung cancer
This study uses a simple blood test to look at bits of tumor DNA (called circulating tumor DNA) to see how well your targeted therapy (TKI) is working. It helps doctors predict and monitor whether the treatment is effective for your advanced lung cancer.
Ho Chi Minh CityAges 18–80 - NCT07084558Recruiting
Testing treatment guided by tumor DNA for hormone positive breast cancer
This trial tests whether using a blood test (circulating tumor DNA) can help guide chemo and hormone therapy for early-stage, hormone receptor positive and HER2 negative breast cancer. The goal is to tailor treatment to your tumor's response, potentially reducing unnecessary side effects.
Vienna, AustriaAges 18–100 - NCT06323460RecruitingPhase 2
Less Radiation for HPV Throat Cancer Guided by a Blood Test
This study tests a way to use less radiation for HPV-related throat cancer. Doctors will adjust your treatment based on a simple blood test that tracks cancer DNA, so you may get only the treatment you need.
Columbus, OhioAges 18 years+ - NCT04768426RecruitingPhase 2
Watching DNA in blood while taking capecitabine after breast cancer
This trial checks how a blood test that looks for cancer DNA (ctDNA) changes during and after you take capecitabine after early triple-negative breast cancer. It aims to see whether these blood test results can help monitor the chance of the cancer coming back.
Stanford, CaliforniaAges 18 years+ - NCT05534087RecruitingPhase 3
Blood test guided chemo after colon cancer surgery
This study tests whether giving additional (adjuvant) chemotherapy based on a special blood test—circulating tumor DNA (ctDNA)—can lower the risk of colon cancer coming back. It targets people with stage II–III colon cancer whose blood test is positive for minimal residual disease (MRD) after completing standard chemo.
BusanAges 19–75 - NCT06257017RecruitingPhase 2
Using DNA tests to guide chemotherapy after bladder cancer surgery
This trial checks if a DNA blood test can help decide who needs extra chemo after bladder or upper urinary tract cancer surgery. It tests whether watching for cancer DNA in the blood can match patients to the right treatment.
Hong Kong, Hong KongAges 18–70 - NCT06762405RecruitingPhase 3
Testing dostarlimab with short radiation for MSI rectal cancer
This trial tests a new approach: giving the immunotherapy drug dostarlimab along with a short course of radiation before surgery, with the goal of avoiding surgery in many patients. It is for people with a specific type of rectal cancer (MSI-H or dMMR) that has not spread to other organs.
DijonAges 18 years+ - NCT05116579Recruiting
Using blood DNA tests to track PARP inhibitor response
This trial uses a blood test (circulating tumor DNA) to see whether PARP inhibitors are working for certain men with advanced prostate cancer. It may help predict which treatment responses are likely and monitor changes over time.
Guangzhou, GuangdongAges 18–75 - NCT06923527RecruitingPhase 2
Testing ctDNA to start elacestrant in early breast cancer
This trial tests whether the drug elacestrant can help prevent recurrence in people with a type of breast cancer (ER+/HER2-) who have finished hormone therapy and have signs of cancer DNA in their blood (ctDNA positive) but no visible spread on scans.
New Haven, ConnecticutAges 18 years+ - NCT07096362RecruitingPhase 2
Using a blood test to guide treatment for advanced pancreatic cancer
This trial tests whether a blood test that detects tumor DNA can help doctors decide early if the standard chemotherapy is working, and if switching treatment might be better. It is for people newly diagnosed with metastatic pancreatic cancer who are starting their first chemotherapy.
Miami, FloridaAges 18 years+ - NCT06966440Recruiting
MRD-Guided Chemotherapy After Pancreatic Cancer Surgery
This trial tests whether using a special blood test (MRD) to guide chemotherapy after pancreatic cancer surgery can improve outcomes. It is for people who have had their cancer completely removed and are ready for standard follow-up therapy.
ShanghaiAges 18–75 - NCT06157060Recruiting
Predicting liver cancer return after surgery with a blood test
This trial is for people with early-stage liver cancer who are scheduled for surgery. It uses a simple blood test to look for tiny bits of tumor DNA after treatment, which may help predict if the cancer will come back.
Foshan, GuangdongAges 18–75 - NCT04120701RecruitingPhase 3
Using blood DNA tests to guide colon cancer treatment after surgery
This trial tests whether a blood test that looks at cancer DNA can help decide whether you need “adjuvant” (extra) chemotherapy after colon cancer surgery. It may help some patients avoid unnecessary chemotherapy while still keeping the cancer from coming back.
DijonAges 18–75 - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT04893564Recruiting
Testing blood DNA after 6 months of Waldenström treatment
This study looks at a blood test called circulating tumor DNA, measured after 6 months of treatment, to see how well it predicts outcomes in people with Waldenström macroglobulinemia. It may help doctors better judge who is responding and who may need treatment adjustments earlier.
AmiensAges 18 years+ - NCT05770531RecruitingPhase 2
Blood test guides chemo changes for metastatic breast cancer
This Phase 2 study uses a blood test that looks for “circulating tumor DNA” to help decide if standard chemotherapy should be changed. It aims to see whether this approach improves how well treatment works for certain metastatic (stage IV) breast cancers.
Nashville, TennesseeAges 18 years+ - NCT06445114RecruitingPhase 2
Blood-Guided Chemoradiation for HPV-Positive Throat Cancer
This study tests whether a blood test that looks for circulating HPV DNA (ctDNA) can help doctors decide if you need chemotherapy after surgery for HPV-positive throat cancer. After you have surgery to remove the cancer, you receive radiation (possibly with chemotherapy) — the results of the blood test guide whether or not to add chemo.
Beverly Hills, CaliforniaAges 18 years+ - NCT06707519Recruiting
Lung cancer breath and blood test study
This study is testing new breath and blood tests to detect lung cancer. It may help find better ways to diagnose and monitor non-small cell lung cancer.
Hamilton, OntarioAges 18 years+ - NCT07025785Recruiting
Testing for tumor DNA in blood after early-stage breast cancer surgery
This study looks for tiny bits of tumor DNA in your blood after surgery to see if it can help guide future treatment. It's for people who had surgery first (not chemotherapy before surgery) and have not seen the cancer spread.
Chapel Hill, North CarolinaAges 18 years+ - NCT07183319RecruitingPhase 2
ctDNA test in advanced bladder cancer
This trial studies how a blood test that looks for tumor DNA (ctDNA) can help guide treatment in people with advanced bladder cancer that cannot be removed by surgery or has spread. It aims to see if the test results can help doctors choose the best therapy.
Oklahoma City, OklahomaAges 18 years+ - NCT06145139Enrolling by invitation
Liquid biopsy for kidney cancer: tracking tumor DNA after surgery
This study looks at whether a simple blood test can detect tiny bits of kidney cancer DNA after surgery. If successful, it could help doctors spot a return of cancer earlier than scans alone.
Aarhus NAges 18 years+ - NCT05227534Recruiting
