Below are recruiting circulating tumor dna clinical trials, each written for real people, not researchers. We’re tracking 87 recruiting studies, each written for real people, not researchers, below.
Recruiting studies
- NCT07183319RecruitingPhase 2
ctDNA test in advanced bladder cancer
This trial studies how a blood test that looks for tumor DNA (ctDNA) can help guide treatment in people with advanced bladder cancer that cannot be removed by surgery or has spread. It aims to see if the test results can help doctors choose the best therapy.
Oklahoma City, OklahomaAges 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 - NCT07222436Recruiting
Blood test for high-risk prostate cancer
This trial studies a blood test that looks for tumor DNA in men with high-risk or advanced prostate cancer. It may help doctors understand the cancer better and guide treatment decisions.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT03357120Recruiting
Using blood DNA to assess response after breast cancer chemotherapy
This study checks whether a blood test that looks for “tumor DNA” (circulating tumor DNA) can help evaluate how well neoadjuvant chemotherapy worked for breast cancer. It may help doctors better understand treatment response after surgery.
BordeauxAges 18 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 - NCT06145139Enrolling by invitation
Liquid biopsy for kidney cancer: tracking tumor DNA after surgery
This study looks at whether a simple blood test can detect tiny bits of kidney cancer DNA after surgery. If successful, it could help doctors spot a return of cancer earlier than scans alone.
Aarhus NAges 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+ - 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+ - 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 - 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 - 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+ - 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+ - 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 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.
