Study of pregnancy-related cell signals in preeclampsia
This study collects samples from pregnant people with preeclampsia (a serious pregnancy blood-pressure condition) and from healthy pregnancy controls. Researchers will study tiny particles (“exosomes”) to see how they differ and whether these signals could help explain or improve care for preeclampsia.

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.
London, United KingdomAges 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+ - NCT07295808Recruiting
Study of IgA antibodies in kidney disease
This study looks at a specific type of antibody called IgA in patients with certain kidney diseases. It aims to understand which IgA antibodies cause kidney damage, which could help develop better treatments.
LimogesAges 18 years+ - NCT07318051Recruiting
Sample collection for cancer research study
This study collects blood and tumor tissue samples from patients with certain untreated cancers to help researchers develop and improve tests. You may be eligible if you have one of the listed cancer types and have not yet started treatment.
Austin, TexasAges 18 years+ - NCT07375940Recruiting
Understanding Behçet Disease in children and teens
This study looks at the health records and blood tests of children and young adults with Behçet disease to learn more about the condition. It also compares their results with healthy children to find clues that may help doctors better understand and treat Behçet disease.
Florence, FlorenceAges 6 months–70 years - NCT07384897Recruiting
Immune cells in lung cancer and chronic lung disease
This study looks at how immune cells work in lung cancer and chronic lung diseases. It aims to find better ways to treat these conditions by studying immune cells from blood, bone marrow, or lung samples.
BrusselsAges Up to 80 years - NCT01993498Recruiting
Study side effects of cancer treatment in localized breast or lung cancer
This study looks at long-term side effects from standard cancer treatments and how they affect daily life and resources. It may help improve care for people with breast or lung cancer that has not spread.
VillejuifAges 18 years+ - NCT06832150Enrolling by invitation

Genetics and cancer risk in families
This study looks at how genes passed down in families might increase the chance of getting cancer. It collects samples from children with cancer and their family members to better understand cancer risks.
CambridgeAges Any age - NCT02280161Recruiting
Study of inherited cancer gene samples in blood and saliva
This study collects blood and saliva to look for inherited gene changes in people who have been diagnosed with cancer. It may help researchers understand what genetic risks could be involved, which could guide future cancer care.

Common questions
- Are there clinical trials studying Blood sample collection?
- Yes. Clin2 currently lists 270 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.
