Study of heart and blood circulation issues during a specific organ donation process
This trial is studying heart and blood circulation problems that may happen during a certain type of organ donation (called Maastricht 3). It is for people who donate organs and those who receive them. The goal is to see how the level of oxygen in the blood affects these problems.
AngersAges 18 years+ - NCT06781515Recruiting
Hairy cell leukemia disease burden study
This study watches the course of hairy cell leukemia (HCL) in different phases—when first diagnosed, after it comes back, or long after successful treatment. The goal is to better understand the disease and plan future care.
Bologna, BolognaAges 18 years+ - NCT06782451Recruiting
Testing tumor samples to find new treatments based on DNA changes
This trial takes a sample of your tumor during a standard procedure to grow it in a lab and test different drugs. The goal is to find which drugs might work best for people with your specific tumor DNA change.
NiceAges 18 years+ - NCT06786949Recruiting
Night shift work and breast cancer risk study

Biomarkers in advanced liver cancer treated with tremelimumab/durvalumab
This study is looking for people with advanced liver cancer (hepatocellular carcinoma) who have not yet had systemic treatment. Participants will receive a combination of two immunotherapy drugs: tremelimumab and durvalumab (the STRIDE regimen). The goal is to find biomarkers that can predict how well the cancer responds to this treatment.

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 700 recruiting studies that include Blood sample, 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 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 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 or a specific trial is right for you.
