Tislelizumab for cancer patients with minimal residual disease
This trial is for people who have completed standard cancer treatments (like surgery, chemo or radiation) and have no visible cancer on scans, but may still have very small amounts of cancer DNA in their blood. The study tests whether the drug tislelizumab can help prevent the cancer from coming back.
Villejuif, Val De MarneAges 18 years+ - NCT07038239Recruiting
MORC2 gene mutation study for nerve and brain conditions
This study looks at how changes in the MORC2 gene relate to nerve or brain development problems. It may help doctors better understand these conditions and improve care.
BesançonAges 4 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+ - NCT07008742Recruiting
Blood and tissue collection study for certain lung cancers
This study collects blood and tissue samples from people with non-small cell lung cancer (NSCLC) either before or after treatment. It aims to help researchers learn more about how tumors respond, especially in cancers with specific genetic changes or after certain pre-surgery therapies.

Genomic study for Native Americans with pancreatic or kidney cancer
This study looks at the genes of pancreatic and kidney cancers in Native American patients to learn more about these diseases and potentially find better treatments. If you join, researchers will use your stored tumor sample for genetic testing.

LeedsAges 18 years+ - NCT06889844Recruiting
Blood test for colorectal cancer cross-reactivity study
This research study uses a blood test to look for signs of colorectal cancer in people who have other types of cancer or digestive diseases. The goal is to see if the test can correctly tell the difference between colorectal cancer and other conditions.
Málaga, AndalusiaAges 18 years+ - NCT06885619Recruiting
Predicting heart outcomes after a first heart attack with blood tests
This study looks at blood tests and heart function after a first heart attack (STEMI) treated with emergency stenting. Researchers want to see if certain molecules in the blood can predict future heart problems.

Common questions
- Are there clinical trials studying Blood sample collection?
- Yes. Clin2 currently lists 269 recruiting studies that include Blood sample collection, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Blood sample collection trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Blood sample collection an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Blood sample collection or a specific trial is right for you.
