Recruiting studies
- NCT04712877Recruiting
Blood and tumor testing to choose the right lung cancer treatment
This trial tests tumor tissue and a blood sample to help doctors pick the most personalized treatment for people with suspected lung cancer. It may help ensure you get therapy matched to your specific tumor characteristics, especially when the cancer might be surgically removed.
Davis, CaliforniaAges Any age - 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+ - 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+ - NCT04157569Recruiting
Study blood DNA markers after chemotherapy in older acute leukemia
This trial checks a blood test called “ctDNA” (tiny pieces of leukemia DNA in blood) after chemotherapy. It may help doctors understand how well treatment is working in older adults with acute leukemia.
BeijingAges 60–100 - NCT06745076RecruitingPhase 2
Using a blood test to safely lower chemo for advanced Hodgkin lymphoma
This trial studies whether a blood test (ctDNA) can help doctors safely reduce chemotherapy for people with advanced Hodgkin lymphoma. If you have stage 3 or 4 Hodgkin lymphoma that hasn't been treated yet and are healthy enough for strong chemo, this study may be an option for you.
Irvine, CaliforniaAges 18 years+ - NCT05116579Recruiting
Using blood DNA tests to track PARP inhibitor response
This trial uses a blood test (circulating tumor DNA) to see whether PARP inhibitors are working for certain men with advanced prostate cancer. It may help predict which treatment responses are likely and monitor changes over time.
Guangzhou, GuangdongAges 18–75 - NCT07058519RecruitingPhase 2
Personalized osimertinib treatment guided by blood test for EGFR lung cancer
This trial tests a personalized treatment plan for advanced lung cancer with an EGFR mutation. It uses a blood test (ctDNA) to guide treatment with osimertinib (a targeted pill) plus chemotherapy. The goal is to see if adjusting therapy based on the blood test results can help you live longer with fewer side effects.
Shanghai, Shanghai MunicipalityAges 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+ - NCT07121335Recruiting
SABR for limited metastatic cancer
This trial tests a precise, high-dose radiation treatment (SABR) for people whose cancer has spread to a few spots (up to 5) and is not growing in the brain or been previously treated with radiation in those same spots.
SeoulAges 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 - NCT07401316Recruiting
Tracking germ cell tumors with a blood test for cancer DNA
This trial looks for signs of cancer DNA in your blood (circulating tumor DNA) to see if it can help track germ cell tumors. It may help doctors find out if your cancer is coming back earlier.
Indianapolis, IndianaAges 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+ - NCT06966440Recruiting
MRD-Guided Chemotherapy After Pancreatic Cancer Surgery
This trial tests whether using a special blood test (MRD) to guide chemotherapy after pancreatic cancer surgery can improve outcomes. It is for people who have had their cancer completely removed and are ready for standard follow-up therapy.
ShanghaiAges 18–75 - NCT07080021Recruiting
Tracking ctDNA for Pancreatic Cancer Before Surgery
This study looks at using a special blood test (ctDNA MRD) to track how well the tumor responds to chemotherapy before surgery for pancreatic cancer. It may help doctors decide if the treatment is working and guide next steps.
ShanghaiAges 18–75 - NCT06197425RecruitingPhase 3
Extra chemotherapy after surgery for colorectal cancer with positive ctDNA
This trial tests whether giving more chemotherapy can help people who still have cancer DNA in their blood after surgery and standard chemotherapy for colorectal cancer. The goal is to prevent the cancer from coming back.
DijonAges 18–80 - NCT06157060Recruiting
Predicting liver cancer return after surgery with a blood test
This trial is for people with early-stage liver cancer who are scheduled for surgery. It uses a simple blood test to look for tiny bits of tumor DNA after treatment, which may help predict if the cancer will come back.
Foshan, GuangdongAges 18–75 - NCT07012954RecruitingPhase 1/Phase 2
ctDNA-guided treatment for RAS/BRAF wild-type colorectal cancer
This trial tests a combination of two drugs—cetuximab or bevacizumab plus a chemotherapy pill (trifluridine/tipiracil)—for people with metastatic colorectal cancer that has no RAS or BRAF mutations. It's for patients whose cancer grew after first responding to cetuximab, and who have had other treatments since then.
Guangzhou, GuangdongAges 18–75 - NCT07681323Recruiting
Timing of ctDNA Testing in Advanced Breast Cancer
This study looks at whether a simple blood test (ctDNA test) can help track advanced breast cancer over time. It aims to see how well the test works for monitoring the disease.
BeijingAges 18 years+ - NCT07264673RecruitingPhase 2
Cemiplimab plus OSE2101 as maintenance after chemo-immunotherapy for lung cancer
This trial tests a combination of two drugs (cemiplimab and OSE2101) as ongoing treatment after initial chemo-immunotherapy for advanced lung cancer. It is for patients whose tumor DNA is still detectable in the blood, and who carry a specific immune marker called HLA-A2.
Roma, RMAges 18–99 - 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.
AvignonAges 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.

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+ - NCT04183712RecruitingPhase 2

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.
