Recruiting studies
- NCT05502523Recruiting
Blood test DNA levels after lung surgery
This study looks at how different lung surgical techniques affect levels of tumor DNA in the blood before and after surgery for early-stage lung cancer. It may help doctors choose surgical approaches and use a blood test to monitor cancer after surgery.
Abington, PennsylvaniaAges 18 years+ - NCT04966663RecruitingPhase 2
Using blood DNA tests to guide lung cancer treatment
This study uses a blood test called ctDNA to look for leftover lung cancer after surgery. Based on that result, the trial will help decide which treatment approach is best for you and may catch cancer returning earlier.
Toronto, OntarioAges 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+ - 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+ - 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+ - 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 - 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.
Chapel Hill, North CarolinaAges 18 years+ - NCT05595408Recruiting
Tracking tumor DNA to predict relapse after upper kidney cancer surgery
This study checks tumor DNA found in blood and urine to see who is at higher risk of the cancer coming back after surgery. It may help doctors identify “minimal residual disease,” meaning tiny amounts of cancer that can remain after treatment.
Shanghai, Shanghai MunicipalityAges 18 years+ - 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+ - 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 - NCT06231953Recruiting
Building a multi-cancer early detection test using DNA
This study uses a blood test to look for DNA changes that could signal cancer early. It includes both people with cancer and healthy volunteers to help build a better screening tool.
SeoulAges 19 years+ - NCT07598747Recruiting
Blood test to detect cancer early using DNA analysis
This study tests whether a new blood test can detect multiple types of cancer early by analyzing DNA fragments in your blood. Researchers are enrolling people recently diagnosed with cancer (before treatment starts) and people without cancer to develop and validate this detection method.
SeoulAges 19 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+ - NCT05710679Recruiting
Blood test predicts leftover cancer after intensified head and neck radiation
This study uses a blood test to see whether cancer DNA is still detectable after a stronger combination of radiation and chemotherapy for locally advanced head and neck cancer. The goal is to predict who may have “residual” (remaining) disease and help guide future care.
Clermont-Ferrand, Puy-de-DômeAges 18–80 - NCT05227534Recruiting
Test for early cancer signals in people without symptoms
This trial checks whether a blood test can detect early signs of multiple cancers in people who feel well. It may help find cancer earlier, when treatment is more likely to work.
Chengdu, SichuanAges 40–75 - NCT06863805Recruiting
Blood markers in advanced thyroid cancer
This study is looking at how certain substances in the blood (called biomarkers) can help doctors understand and treat advanced thyroid cancer. It is for people who are about to start their first systemic therapy (medication that works throughout the body) for advanced thyroid cancer, and who have already had a genetic test on their tumor.

Common questions
- Are there clinical trials for circulating tumor dna?
- Yes. Clin2 currently lists 88 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.
