Recruiting studies
- 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+ - 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 - 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+ - 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 - 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+ - NCT07335081RecruitingPhase 2
ctDNA in HER2-positive early breast cancer before surgery
This trial is testing whether monitoring ctDNA (genetic material from the tumor in your blood) can help guide treatment for HER2-positive breast cancer before surgery. It is for people with early-stage (Stage II or III) disease who have not yet started treatment.
ShanghaiAges 18–70 - NCT07356882Recruiting
Using ctDNA to monitor treatment in young Hodgkin lymphoma patients
This study uses a blood test to detect cancer DNA (ctDNA) in children and young adults with classical Hodgkin lymphoma. The goal is to see if this non-invasive test can help track how well treatment is working.
ParisAges Any age - NCT02579278Recruiting
Tests blood DNA and scans in early colon cancer surgery
This study looks at a blood test that detects cancer DNA (ctDNA) and compares it with CT scan findings before surgery. It may help doctors understand how aggressive the cancer is and how scan features relate to blood test results.
Margate, KentAges 16 years+ - NCT06098560Recruiting
ctDNA as a marker for immunotherapy in advanced colorectal cancer
This study looks at whether a blood test for tumor DNA (ctDNA) can predict how well immunotherapy works in people with advanced or locally advanced colorectal cancer that has specific genetic features (dMMR/MSI-H). If you qualify, the trial will monitor your ctDNA levels while you receive standard immunotherapy to see if changes in those levels can show early on if the treatment is working.
Beijing, Beijing MunicipalityAges 18–80 - NCT07425054RecruitingPhase 2
Chemoradiation with or without immunotherapy for anal cancer
This trial tests whether adding an immunotherapy drug (retifanlimab) to standard chemoradiation improves outcomes for people with locally advanced anal cancer. The treatment is adjusted based on HPV DNA levels in your blood.
Cleveland, OhioAges 18 years+ - NCT07452432Recruiting
Study of chemo before surgery for aggressive kidney/ureter cancer
This study tests whether giving chemotherapy before surgery can help patients with high-grade upper tract cancer that hasn't spread. It aims to find better ways to treat this aggressive cancer.
SeoulAges 19 years+ - NCT07459673RecruitingPhase 2
HER2-positive breast cancer trial using ctDNA to guide treatment
This trial tests a personalized treatment plan for HER2-positive breast cancer that has spread. It uses a blood test to track cancer DNA and adjust therapy, including treatments that may help prevent cancer from reaching the brain. The goal is to achieve long-term remission.
Basking Ridge, New JerseyAges 18 years+ - NCT07491328Recruiting
Liquid biopsy for nerve disorders linked to cancer
This study uses a blood test (liquid biopsy) to look for cancer-related signals in people with certain nerve disorders caused by the immune system (paraneoplastic neurological syndromes) or in people with tumors that do not affect the nerves. It aims to better understand and detect these conditions.
DüsseldorfAges 18 years+ - NCT07504796RecruitingPhase 4
Adding ipilimumab to standard melanoma therapy based on ctDNA
This trial tests whether adding a second immunotherapy drug (ipilimumab) to the standard first-line combo of nivolumab and relatlimab improves outcomes for advanced melanoma. It uses a blood test (ctDNA) to decide who gets the extra drug.
New York, New YorkAges 18 years+ - NCT07516678Recruiting
Blood Tests to Track Neuroblastoma During Treatment
This study collects blood samples from neuroblastoma patients to test for tiny pieces of tumor DNA that can show how well treatment is working. By tracking these markers over time, doctors hope to better predict how patients will respond and improve care.
Guangzhou, GuangdongAges Any age - NCT07517107RecruitingPhase 2
Blood tests to guide gastric cancer treatment decisions
This study uses special blood tests to detect cancer DNA and help doctors decide the best treatment plan for gastric cancer. The goal is to improve outcomes by personalizing therapy based on how your cancer responds.
ShanghaiAges 18 years+ - NCT07536113Recruiting
Blood Test to Guide Second Colorectal Cancer Treatment
This study looks at whether a simple blood test can help doctors decide if you should receive a specific type of cancer drug again. The blood test looks for cancer DNA to predict if the drug will work for your advanced colorectal cancer.
Milan, ItaliaAges 18 years+ - NCT07581496Recruiting
Blood test to detect bladder cancer DNA after surgery
This study examines whether a simple blood test can detect cancer DNA (circulating tumor DNA, or ctDNA) in patients with a specific type of bladder cancer. Detecting this DNA in blood may help doctors predict how the cancer will behave and guide future treatment decisions.
BaselAges 18 years+ - NCT07660627Recruiting
ctDNA test for tracking cancer after treatment
This trial uses a blood test to find tiny bits of tumor DNA after treatment. It helps doctors see if any cancer remains, which could guide next steps for people with esophageal, stomach, or pancreatic cancer.

Common questions
- Are there clinical trials for ctdna?
- Yes. Clin2 currently lists 187 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.
