Decoding liver cancer immune evasion with advanced testing
This trial studies liver cancer tissue to understand how the tumor hides from the immune system. The goal is to use this knowledge to improve future treatments.
Milan, LombardyAges 18 years+ - NCT03207854Recruiting
Donate blood and immune samples for cancer, blood, or healthy volunteers study
This study collects blood and immune-related samples from people with cancer, certain immune-related blood conditions, or healthy volunteers. It helps researchers understand immune changes and may support future diagnosis or treatments.
Los Angeles, CaliforniaAges 19 years+ - NCT06710418Recruiting
Comparing two red blood cell transfusion thresholds for people with high-grade myeloid neoplasms, AML or B-ALL
This study compares two different strategies for when to give red blood cell transfusions to people receiving intensive chemotherapy or stem cell transplant for high-grade myeloid neoplasms, AML or B-ALL. The goal is to see which approach better improves quality of life and daily function.
Seattle, WashingtonAges 18 years+ - NCT03268668Recruiting
Study brain clot makeup and blood markers after stroke
This study looks at the composition of a stroke blood clot and compares it with blood test results to understand treatment response, stroke cause, and prognosis. It may help doctors better predict outcomes and improve care after ischemic stroke.
BordeauxAges 18 years+ - NCT06878105Recruiting
Blood management study for surgical patients
This study looks at how hospitals manage your blood during and after planned surgeries that have a moderate to high risk of bleeding. It aims to find better ways to reduce blood loss and the need for transfusions.
BudapestAges 18 years+ - NCT07131605Recruiting
How weight-loss surgery affects heart health and inflammation
This study looks at how weight-loss surgery affects heart health by checking markers of inflammation in the blood and how blood vessels work. It may help understand why surgery lowers heart risk for people with obesity.
Cotignola, RavennaAges 18 years+ - NCT00071045Enrolling by invitation
Tissue Collection From Cancer and Blood Disorder Patients
This study collects tissue samples from patients with cancer or blood disorders, and from their matching family members who might donate stem cells for transplant. The samples help researchers understand these diseases and develop better treatments.
Bethesda, MarylandAges 2–100 - NCT05212272Recruiting
MRI plus cognitive testing during glioma chemoradiation
This study uses MRI scans and related brain/cognitive testing while you receive standard chemotherapy and radiation for a high-grade brain tumor. It aims to see how MRI measures and brain testing may relate to your treatment response or brain function.
Winston-Salem, North CarolinaAges 18 years+ - NCT03958240Recruiting
Study how cancers trigger the immune system

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 348 recruiting studies that include Blood 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 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 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 collection or a specific trial is right for you.
