Recruiting studies
- 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 - NCT06088381RecruitingPhase 2
HPV-related throat cancer treatment based on tumor DNA levels
This trial tests if monitoring cancer DNA left in your blood after surgery can help decide if you need additional treatment. It is for people with HPV-positive oropharynx (throat) cancer who have a certain amount of cancer DNA detected before surgery.
Baltimore, MarylandAges 18 years+ - NCT06071286Recruiting
Study tracking DNA from tumors in advanced ovarian cancer
This study looks for cancer DNA in your blood to understand advanced ovarian cancer better. It helps doctors see how the disease changes over time and may improve future treatments.
RomaAges 18–80 - NCT06050694RecruitingPhase 2
Testing glofitamab plus chemo for untreated DLBCL
This trial tests a new drug called glofitamab combined with standard Pola-R-CHP chemotherapy for people with untreated DLBCL. The goal is to see if using PET scans and blood tests early on can guide treatment and improve outcomes.
Toronto, OntarioAges 18 years+ - NCT05987241RecruitingPhase 2/Phase 3
Using a blood test to guide immunotherapy after bladder/kidney cancer surgery
This study tests whether a blood test that detects tumor DNA can help guide the use of immunotherapy (nivolumab with or without relatlimab) after surgery for urothelial cancer. The goal is to see if starting immunotherapy based on the blood test results can prevent the cancer from coming back.
Phoenix, ArizonaAges 18 years+ - NCT05947838Recruiting
Blood test helps choose chemotherapy before colorectal or appendix surgery
This study uses a blood test called ctDNA to help tailor (personalize) neoadjuvant chemotherapy for people with colorectal or appendix cancer before surgery. The goal is to see if using ctDNA can help doctors pick the most appropriate chemotherapy plan for you.
Houston, TexasAges 18 years+ - NCT05917106Recruiting
Testifying methylomics blood test for new kidney cancer monitoring
This study follows people with newly diagnosed kidney cancer who have not started treatment. It tests whether a special blood test can monitor the cancer over time, alongside standard follow-up after planned surgery.
Nanjing, JiangsuAges Any age - NCT05868226RecruitingPhase 1/Phase 2
Personalized cancer treatment study for advanced solid tumors
This study tests different treatments tailored to your cancer's biology. It aims to find which therapy might work best for you, potentially improving outcomes. You'd receive one of the study drugs, with close monitoring and support.
Birmingham, AlabamaAges 18 years+ - NCT05441566Enrolling by invitation
Checking MRD after surgery in early lung cancer
This study looks at a test called MRD (tiny remaining cancer after treatment) after surgery for early-stage lung cancer. It aims to understand who is more likely to have the cancer return, which could help guide follow-up care.
ShenzhenAges 18–100 - NCT05254782Recruiting
Blood test after lung tumor surgery to find hidden disease
This study uses a special blood test to look for tiny traces of lung cancer after surgery. It aims to find “minimal residual disease,” meaning cancer cells that may still be hiding after your tumor is removed.
Toronto, OntarioAges 18 years+ - NCT05081024Recruiting
Blood test biomarker to help preserve organs in rectal cancer
This study looks at a blood test (ctDNA, a way to detect cancer DNA in the bloodstream) to help doctors choose treatment that may spare organs for people with stage II–III rectal cancer. You may be followed to see how well the blood test can guide treatment decisions.
Portland, OregonAges 18 years+ - NCT05027828Recruiting
Blood test may track ovarian cancer treatment response
This study checks whether a blood test (ctDNA) can show how well ovarian, fallopian tube, or primary peritoneal cancer treatment is working. If the test reliably reflects response, it could help doctors adjust treatment earlier and more precisely.
ShanghaiAges 18 years+ - NCT05062317RecruitingPhase 2
Blood test-guided chemotherapy after liver tumor removal
This trial uses a blood test (ctDNA, a sign of cancer cells shedding into the blood) to help guide chemotherapy after surgery to remove colorectal liver metastases. It may help patients get the right chemotherapy plan after their operation, potentially based on whether cancer material is still detectable.
Houston, TexasAges 18 years+ - NCT05052671Recruiting
Blood test for residual cancer in resectable pancreatic cancer
This trial studies a blood test that looks for tiny traces of cancer-related DNA (called ctDNA) in people with pancreatic cancer that can be removed with surgery. The goal is to see whether this test can better predict how the cancer behaves and guide treatment decisions around surgery.
Oklahoma City, OklahomaAges 18–99 - NCT04900623RecruitingPhase 2
Using HPV blood test to guide treatment for HPV throat cancer
This Phase 2 study tests a “risk-adapted” treatment plan for HPV-related throat cancer, using an HPV DNA blood test to help decide how treatment is done. If your baseline blood test shows detectable HPV DNA, the study may help tailor therapy to your risk and potentially improve outcomes while limiting unnecessary treatment.
Boston, MassachusettsAges 22 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+ - NCT04616131Recruiting
Testing ctDNA as a marker in pancreatic cancer treatment
This trial is studying a blood test that looks for tumor DNA (ctDNA) to see if it can help predict how well treatment is working in people with pancreatic cancer that hasn't spread. It is for patients getting chemotherapy before possible surgery.
DeKalb, IllinoisAges 18 years+ - NCT04354064Recruiting
Blood DNA test to see early treatment response in solid tumors
This study looks at circulating tumor DNA, which is tiny bits of DNA found in blood, to help assess how solid tumors are responding early. It uses blood samples from healthy adults who are willing to donate.
St Louis, MissouriAges 18 years+ - NCT04099290Recruiting
Blood DNA test in newly diagnosed head and neck cancer
This study looks at “circulating tumor DNA” (tumor DNA found in blood) in people with newly diagnosed, locally advanced head and neck squamous cell cancer. Researchers want to see how the blood DNA levels relate to the cancer and how it may guide treatment after surgery.

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.
