Using RNA modifications to diagnose and treat gliomas
This trial studies whether changes in RNA (the instructions inside cells) can help doctors better diagnose and treat gliomas, a type of brain tumor. If you are scheduled for surgery to remove a suspected glioma and have not had prior treatment, you may be able to join.
Montpellier, HéraultAges 18 years+ - NCT01137643Recruiting
Sharing blood and tissue samples for blood cancer research
This trial collects tissue, blood, and other body fluid samples from people with blood-related cancers. The goal is to help researchers study these diseases by building a source of samples for future testing.
Chapel Hill, North CarolinaAges 18–120 - NCT07760480RecruitingPhase 4
Intensified treatment for lupus nephritis
This study tests whether adding a drug called voclosporin to the usual treatment for lupus nephritis (a kidney disease caused by lupus) can better reduce kidney inflammation. It also looks at the role of immune cells in this process.

Test how the gut microbiome changes during major cancer treatment
This study looks at your gut “microbiome” (the bacteria in your intestines) while you receive high-dose chemotherapy and a stem cell transplant, or CAR-T cell therapy. Researchers hope to understand how these treatments affect the microbiome, which may relate to how well patients do.
Bratislava, SlovakiaAges 18 years+ - NCT04896684Recruiting
Study collecting gut health information from adults’ scans
This study is looking at people who need an intestinal scope (endoscopy) for gut symptoms or bowel conditions like IBS, IBD, or possible colorectal cancer. Your results may help doctors better understand these long-term conditions and improve follow-up care.
ToulouseAges 18–99 - NCT06101303Recruiting
Endometriosis pain study using surgery and surveys
This study looks at pain in people with or without endometriosis who are having laparoscopic surgery. Researchers want to understand more about pelvic pain by collecting information before, during, and after surgery.
St Louis, MissouriAges 12–45 - NCT05007340Recruiting
ILD and autoimmune conditions registry and sample storage
This study collects health information and may store blood or other samples to learn more about interstitial lung disease (ILD) and autoimmune-related conditions. Joining could help researchers understand different causes of ILD and improve future care.
Montreal, QuebecAges 18 years+ - NCT05736029Recruiting
Using blood and tumor data to predict cancer treatment response
This study looks at “multiomics” information (many types of biological data, like blood and lab markers) to predict how well cancer treatments may work for you. It may help doctors choose better treatments in the future based on what your body is doing during therapy.
Dallas, TexasAges 18 years+ - NCT05775458Recruiting
Study of treatments for aggressive brain tumor cell damage
This study looks at glioblastoma (GBM), a very aggressive brain tumor, and how “brain cell overload” (glutamate excitotoxicity) may affect tumor growth. It focuses on adults who are planned for complete tumor removal, followed by standard radiation and chemotherapy.
Milan, MilanAges 18 years+ - NCT06053671Recruiting
Understanding genetics in focal epilepsy brain tissue
This study is looking at brain tissue from people with a specific type of epilepsy (Focal Cortical Dysplasia Type II). The goal is to understand what causes the seizures and how they develop, which may help improve future treatments.
LondonAges Any age - NCT06130787Recruiting
Using your body's age to personalize CML treatment
This study looks at how your 'biological age' (how old your body seems) affects how well you do on targeted therapy for chronic myeloid leukemia. It aims to personalize your care by combining age and frailty information.
AnnecyAges 18 years+ - NCT06640959Recruiting
Bowel health study for prostate cancer radiation
This study tests whether a daily drink can help reduce bowel side effects caused by radiation for prostate cancer. If you are about to start radiation for intermediate to high-risk prostate cancer, you may be able to join.
Manchester, Greater ManchesterAges 18 years+ - NCT06649253Recruiting
CD9 Gene and Relapse in Childhood B-ALL Study

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 695 recruiting studies that include Blood samples, 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 samples 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 samples 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 samples or a specific trial is right for you.
