Recruiting studies
- NCT06928675Recruiting
Cell-free DNA in acute stroke
This study looks at how a substance called cell-free DNA in the blood changes in people with a large blood clot causing a stroke. It aims to improve understanding of this condition and might help with future treatments.
BaselAges 18 years+ - NCT07176962Recruiting
Blood test for early detection of bile duct cancer
This study is testing a new blood test that looks for signs of DNA changes linked to biliary tract cancer. It aims to see if the test can find these cancers early. If you have biliary tract cancer or a high suspicion of it, you may be able to help.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT07170735Recruiting
Measuring TB DNA in blood and urine for diagnosis
This study looks for TB DNA in blood and urine samples to see if it can help diagnose tuberculosis (TB) more quickly. It includes people with active TB, those with a latent (hidden) TB infection, and healthy volunteers without TB.
Hong Kong, Hong KongAges 18 years+ - NCT07106853Recruiting
New prenatal DNA test for high-risk pregnancies
This study tests a new blood test that can screen for genetic problems in babies during pregnancy. It may find more conditions than standard tests, especially for pregnancies with certain ultrasound findings or other risk factors.
Hangzhou, ZhejiangAges 18 years+ - NCT07006831Recruiting
Blood study for kidney transplant patients
This study collects blood and leftover donor samples from kidney transplant recipients who need a biopsy. The goal is to improve monitoring after transplant.
San Diego, CaliforniaAges 18 years+ - NCT06808880Recruiting
Expanding prenatal screening for single-gene disorders
This study looks at a new blood test to screen for single-gene disorders (conditions caused by changes in one gene) during pregnancy. It may help if you or your baby's father carry a genetic disorder, or if an ultrasound shows signs of a possible genetic condition.
Glendale, ArizonaAges 18 years+ - NCT06726642Recruiting
Blood test study for people with inherited cancer risk
This study looks for DNA fragments in blood of people with certain inherited cancer syndromes. It may help find cancer earlier or guide better monitoring. You would give blood samples every 4 months (if in the experimental group).
Vancouver, British ColumbiaAges Up to 90 years - NCT06679257Recruiting
Liquid biopsy for lung transplant damage classification
This study tests a simple blood test (liquid biopsy) to detect and classify damage to a transplanted lung. It aims to find signs of rejection or injury earlier, which could help doctors treat problems sooner.
Gothenburg, Västra Götaland CountyAges 18 years+ - NCT06646237Recruiting
Using a blood test to diagnose TB in pleural fluid
This study tests a new blood test that looks for TB DNA to see if it can help diagnose tuberculosis in people who have fluid around one lung. If the test works, it might make diagnosing TB faster and less invasive.
Hong Kong, Hong KongAges 18 years+ - NCT06308510Recruiting
Improving stomach cancer detection with a fluid test
This study tests whether looking for certain DNA changes in the fluid from your belly can help doctors find stomach cancer that has spread. The goal is to make standard tests more accurate so treatment can be better planned.
RotterdamAges 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 - NCT05084768Recruiting
Test blood markers to predict kidney transplant rejection
This study looks at special blood tests to help predict when kidney transplant rejection might happen. If the markers work, they could help doctors catch rejection earlier and adjust treatment sooner.
Loma Linda, CaliforniaAges 18 years+ - NCT04050345Recruiting
Blood test to spot DNA changes after early colon cancer surgery
This study checks a “cell-free tumor DNA” blood test to see if cancer mutations can predict relapse after surgery for early colorectal cancer. If results look risky, they may help guide closer follow-up and future treatment decisions.
Milton Keynes, BuckinghamshireAges 18 years+ - NCT07639333Recruiting
Understanding Early Pregnancy Loss Through Genetic Testing
This study examines genetic material from miscarriages to understand why early pregnancy loss happens. Researchers analyze a blood sample taken right after miscarriage to look for clues that might help explain what went wrong and potentially prevent future losses.
RennesAges 18–43 - NCT05307939RecruitingPhase 2
Using tumor DNA tests to time treatment for HPV throat cancer
This study checks a blood test that looks for HPV tumor DNA to help doctors decide when to start routine treatment after surgery. It may help some people avoid starting treatment too early or too late based on how the test changes after the operation.
Miami, FloridaAges 18 years+ - NCT07698535RecruitingPhase 2
Blood test to guide early stopping of prostate cancer therapy
This trial uses a blood test to measure tumor DNA and see if men with advanced prostate cancer can safely stop treatment with a drug called 177Lu-PSMA-617 earlier than usual, or switch to chemotherapy. It may help reduce side effects while still controlling the cancer.
Seattle, WashingtonAges 18 years+ - NCT06864806Recruiting
Prenatal blood test for fetal DNA
This study looks at a simple blood test that can check the unborn baby's DNA during pregnancy. It may help doctors learn more about the baby's health without any risk to you or the baby.
BordeauxAges 18 years+ - NCT03786796RecruitingPhase 2
Olaparib for metastatic kidney cancer with specific DNA repair gene changes
This trial tests olaparib (a pill medicine) in people with kidney cancer that has spread and specific DNA “repair” gene mutations. The goal is to see whether this targeted treatment can slow the cancer or help it respond better after prior immunotherapy or blood-vessel–blocking therapy.
Baltimore, MarylandAges 18–120 - NCT05791149Recruiting
Saliva test to help diagnose oral cavity cancer
This study looks for changes in saliva (epigenetic biomarkers) that may help doctors diagnose squamous cell carcinoma in the mouth. You may be asked for saliva samples and usual clinical checks to see whether the test can help with diagnosis, especially before surgery.
Amiens, PicardieAges 18 years+ - NCT05962242RecruitingPhase 2
HPV-tested de-escalated radiation for HPV-related throat cancer
This Phase 2 study uses HPV test results from your tumor to safely lower (de-intensify) the strength of radiation for some HPV-positive oropharyngeal throat cancers. It aims to reduce side effects while keeping cancer control effective.
Miami, FloridaAges 18 years+ - 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+ - NCT07625527RecruitingPhase 2
Stopping immunotherapy after bladder cancer disappears
This trial tests whether it's safe to stop immunotherapy once bladder cancer is no longer visible, instead of continuing it for a longer time. It aims to find out if stopping treatment early can reduce side effects while keeping the cancer from coming back.
TianjinAges 18 years+ - NCT06323460RecruitingPhase 2
Less Radiation for HPV Throat Cancer Guided by a Blood Test
This study tests a way to use less radiation for HPV-related throat cancer. Doctors will adjust your treatment based on a simple blood test that tracks cancer DNA, so you may get only the treatment you need.

Common questions
- Are there clinical trials for cell free dna?
- Yes. Clin2 currently lists 47 recruiting cell free 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 cell free 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 cell free 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.
