Recruiting studies
- NCT05787197Recruiting
Blood test to guide treatment after colon cancer liver surgery
This trial studies a blood test (called ctDNA) in people with colon cancer that has spread to the liver and is being removed with curative surgery. The goal is to see how the blood test can help with planning and improving treatment after surgery.

Personalized chemotherapy reduction for advanced Hodgkin lymphoma
This trial tests a personalized approach to using a blood test (ctDNA) to decide how much chemotherapy you need. If you have advanced Hodgkin lymphoma, this study might let you have less chemo if the blood test shows a strong response early on, potentially reducing side effects.
Irvine, CaliforniaAges 18 years+ - NCT06706557Recruiting
Studying tumor DNA in HER2-low advanced breast cancer
This trial looks at tumor DNA in the blood of people with a certain type of advanced breast cancer called HER2-low. The goal is to learn more about this cancer and how it changes over time, which may help guide future treatments.
Milan, MIAges 18 years+ - NCT06693830Recruiting
Blood test guided treatment for newly diagnosed DLBCL
This trial studies whether using a blood test (ctDNA) can help guide treatment decisions for people with newly diagnosed diffuse large B-cell lymphoma. It tests standard chemotherapy regimens (R-CHOP or R-pola-CHP) and aims to improve outcomes by monitoring tumor DNA in the blood.
New York, New YorkAges 18 years+ - NCT06666439Recruiting
Tracking lobular breast cancer with a blood test
This study is testing a new blood test that looks for cancer DNA to track how lobular breast cancer responds to treatment. It is for people whose cancer has spread and who have not yet started treatment for the spread.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06617858RecruitingPhase 2
AMB-05X for colorectal cancer with ctDNA after treatment
This trial tests a drug called AMB-05X for people with colorectal cancer who have completed all intended treatments and show no signs of cancer on scans, but still have cancer DNA (ctDNA) in their blood. The goal is to see if AMB-05X can eliminate this remaining cancer DNA and prevent the cancer from coming back.
Houston, TexasAges 18 years+ - NCT06610682RecruitingEarly Phase 1
Plixorafenib for BRAF-mutated glioma
This study tests a new targeted drug called plixorafenib, either alone or combined with another drug (retifanlimab), for people with a BRAF-mutated brain tumor. The goal is to see if the drug can reach the brain and control the tumor, while checking for side effects.
Baltimore, MarylandAges 18 years+ - NCT06606028Recruiting
Blood test for leftover cancer DNA after head and neck cancer treatment
This study uses a simple blood test to look for leftover cancer DNA after treatment for head and neck squamous cell carcinoma. The goal is to see if the test can find very small amounts of cancer early, which might help doctors make better decisions about follow-up care.
San Francisco, CaliforniaAges 18 years+ - 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+ - NCT06202131Recruiting
Blood test for tumor DNA in gastrointestinal cancers
This trial uses a blood test (ctDNA) to look for genetic material from tumors in patients with gastrointestinal cancers. It may help doctors understand and track your cancer better.
Rome, LazioAges 18–85 - NCT05366816RecruitingPhase 2
Blood test–guided sunitinib or regorafenib for GIST
This study uses a blood test (ctDNA) to look for specific tumor DNA changes, then guides treatment with sunitinib or regorafenib in people with GIST that has spread or cannot be removed by surgery. It aims to see whether this ctDNA-guided approach improves outcomes compared with standard decision-making.
Miami, FloridaAges 18 years+ - NCT06479070Recruiting
Using ctDNA to guide radiotherapy for head and neck cancer
This study looks at whether measuring a DNA fragment in the blood (called ctDNA) can help predict how well radiotherapy works for head and neck cancer. It may help doctors better tailor treatment for patients with stage III or IV disease.
Caen, CaenAges 18 years+ - NCT06463262Recruiting
Personalized markers for chordoma before surgery and radiation
This trial tests whether analyzing blood and tumor samples before and after radiation and surgery can help find personalized markers for chordoma. It is for patients with chordoma of the skull base, spine, or sacrum who will receive radiation before surgery.
Baltimore, MarylandAges 18 years+ - NCT06426511RecruitingPhase 2
Testing toripalimab after lung cancer surgery using ctDNA
This study tests whether a drug called toripalimab, given after lung cancer surgery, can help keep the cancer from coming back in people with early-stage non-small cell lung cancer. It uses a blood test (ctDNA) to look for leftover cancer cells and decide who might benefit most.
Guangzhou, GuangdongAges 18–75 - NCT06434896Recruiting
Blood test to guide chemotherapy in stage II colon cancer
This trial is for people with stage II colon cancer who are not currently getting chemotherapy. It uses a blood test to look for tumor DNA, so doctors can decide if chemotherapy might help prevent the cancer from coming back.
's-HertogenboschAges 18 years+ - NCT06401421Recruiting
Blood test for tumor DNA after breast cancer chemo
This study tests a new blood test to see if it can find tiny bits of tumor DNA after chemotherapy. If you have a larger or higher-risk breast cancer and are getting chemotherapy before surgery, you may join. The test could help doctors know if your cancer is gone or if more treatment is needed.
Anchorage, AlaskaAges 18 years+ - NCT04790682Recruiting
Liquid blood test to predict first immunotherapy response
This trial tests whether a “liquid biopsy” blood test can help predict how well first immunotherapy will work for people with stage IV lung cancer. It may help doctors choose the most effective treatment strategy sooner.
Boulogne-BillancourtAges 18 years+ - NCT05904665Recruiting
Blood methylation test to guide follow-up after colon cancer surgery
This study checks a special blood test (circulating tumor DNA methylation) to help guide follow-up after surgery for non-metastatic colon cancer. It may help find whether additional treatment or closer monitoring is needed based on the test results.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06087120Recruiting
Can a blood test predict breast cancer treatment response?
This study looks at whether a blood test (ctDNA) can help predict how well breast cancer responds to chemotherapy before surgery. It focuses on people with HER2-positive or triple-negative breast cancer that has not spread far.
JakartaAges 18 years+ - NCT06287723Recruiting
Blood test for cancer DNA after liver surgery in colorectal cancer
This study uses a simple blood test (liquid biopsy) to look for tiny bits of cancer DNA after surgery for colorectal cancer that spread to the liver. It aims to see if this test can find cancer earlier than standard scans, which may help guide future treatment decisions.
MontpellierAges 18 years+ - NCT06225505Recruiting
Early detection of triple-negative breast cancer return
This trial uses blood tests to look for signs of cancer returning early in women who had triple-negative breast cancer. If caught early, doctors can start treatment sooner.

Common questions
- Are there clinical trials for ctdna?
- Yes. Clin2 currently lists 189 recruiting ctdna 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 ctdna 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 ctdna 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.
