Hanzhou, ZhejiangAges 18–75 - NCT06247449Recruiting
MRI screening for brain metastases in aggressive breast cancer
This trial uses an MRI scan to look for early signs of breast cancer spreading to the brain in people with certain aggressive breast cancer types (triple-negative or HER2-positive) that are stage IIb or III. The goal is to find and treat brain metastases earlier, before they cause symptoms.
Toronto, OntarioAges 18 years+ - NCT06307938Recruiting
Liquid biopsy test for colorectal cancer before colonoscopy
This trial tests a simple blood test (liquid biopsy) to find cancer signals in the DNA of people being called for a colonoscopy. If you are scheduled for a colonoscopy, your blood sample could help doctors detect colorectal cancer earlier and plan better treatment.
LevangerAges 18 years+ - 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+ - NCT07023289RecruitingPhase 2
Study of Telisotuzumab Adizutecan for ctDNA-Positive Colorectal Cancer
This trial tests a new drug, Telisotuzumab Adizutecan, given through a vein (infusion) alone or with standard treatments for people with colorectal cancer who have no visible tumors on scans but still have cancer DNA (ctDNA) in their blood after surgery and chemotherapy.
Huntsville, AlabamaAges 18 years+ - NCT06358222Recruiting
Lung cancer trial testing blood test and PET scan for spread
This trial studies if a blood test that looks for tumor DNA combined with a PET-CT scan can better predict if lung cancer has spread to lymph nodes. It may help guide treatment decisions for people with non-small cell lung cancer that hasn't been treated yet.
ShanghaiAges 18–75 - 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+ - NCT06479460Recruiting
Blood test monitoring during chemo before surgery for HER2-positive breast cancer
This trial tests whether a blood test (ctDNA) can help doctors monitor how well chemotherapy before surgery is working in women with HER2-positive breast cancer. It aims to see if changes in the blood can predict treatment success.
Nanjing, JiangsuAges 18–75 - NCT06614647Recruiting
Digital follow-up for colorectal cancer survivors
This trial tests a smartphone-based follow-up program for people who have been treated for early-stage colorectal cancer. The goal is to see if a digital, need-based care guide can replace standard follow-up visits.
Herning, Central JutlandAges 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+ - NCT06716580Recruiting
Lung cancer screening for Asian and Latinx communities
This study uses a blood test to look for signs of lung cancer in people who have never smoked or smoked very little. It focuses on Asian and Latinx communities because certain gene changes are more common in these groups.
Boston, MassachusettsAges 40–80 - NCT06736613RecruitingPhase 2
Blood test for tumor DNA in high-risk B-cell lymphoma
This trial uses a blood test to look for tumor DNA in people with high-risk B-cell lymphoma, to help predict if the lymphoma might spread to the brain or spinal cord. It may help doctors decide on extra treatments to prevent that spread.
Basking Ridge, New JerseyAges 18 years+ - NCT06828991RecruitingPhase 2
Mosunetuzumab for older DLBCL patients with residual ctDNA
This trial tests whether adding a targeted immunotherapy drug called mosunetuzumab after standard chemotherapy can help older adults with DLBCL who still have tiny traces of cancer DNA in their blood. If you qualify, the goal is to reduce the chance of the cancer coming back.
Rochester, New YorkAges 70 years+ - NCT06958107Recruiting
Liquid biopsy study for sarcoma patients
This study uses a simple blood test (liquid biopsy) to look for tiny pieces of tumor DNA in people with sarcoma. It may help doctors learn more about the disease and guide treatment decisions, whether you are just diagnosed, being treated, or have finished treatment recently.
Charlotte, North CarolinaAges Any age - NCT06989814Recruiting
Liquid biopsy test for Lynch syndrome cancer patients
This trial tests a simple blood test to measure tumor DNA in people with Lynch syndrome who have been newly diagnosed with cancer but haven't started treatment yet. It aims to see if this test can help monitor the cancer.
Leiden, South HollandAges 18 years+ - NCT06992336RecruitingPhase 2
Circulating tumor DNA guided extra treatment for early triple-negative breast cancer
This trial tests whether using a blood test to detect leftover cancer DNA after initial treatment can help doctors decide if extra therapy is needed for people with early triple-negative breast cancer. It aims to improve outcomes for those with remaining disease after neoadjuvant therapy.
Guangzhou, GuangodngAges 18–70 - 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+ - NCT07069595RecruitingPhase 2
Blood test for breast cancer survivors at risk of recurrence
This trial uses a simple blood test to look for leftover cancer DNA in people with triple-negative breast cancer who still have disease after chemotherapy and surgery. It aims to catch any early signs of the cancer coming back.
Chapel Hill, North CarolinaAges 18 years+ - 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.

Common questions
- Are there clinical trials for circulating tumor dna?
- Yes. Clin2 currently lists 87 recruiting circulating tumor dna studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a circulating tumor dna trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a circulating tumor dna trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
