Collecting blood and tumor samples for cancer research
This study collects and stores tumor and blood samples from children and young adults with cancer, blood disorders, or immune conditions. The samples are used to better understand these diseases and could help future treatments.
FlorenceAges birth–30 years - NCT07715435Recruiting
Collecting samples to improve echinococcosis testing
This study collects tissue and blood samples from people having surgery for echinococcosis. The samples will help develop a better PCR test (a lab test that detects the parasite) so doctors can diagnose the infection more accurately.
Alessandria, Piemonte, ItalyAges 6 years+ - NCT04290000Recruiting
Share samples after CAR-T treatment at Montpellier hospital
This study collects and stores biological samples from people who have been treated with CAR-T cells at the University Hospital of Montpellier. Your samples can help researchers learn more about treatment effects and safety.
MontpellierAges 18 years+ - NCT04883502Recruiting
Testing a technique to rebuild bone lost after injury
This study looks at a surgical method that creates an “induced membrane” to help rebuild bone after traumatic injury. It may help people whose limb bones were damaged and are missing part of the bone.
ClamartAges 18 years+ - NCT07417085Recruiting
Study of gut bacteria in children with brain tumors
This study looks at how gut bacteria (the microbiome) may differ in children with brain tumors. Researchers will collect samples before and after surgery to understand the connection between gut health and brain tumors.
Florence, FirenzeAges 3–18 - NCT04343430Recruiting
Hospital study for fluid buildup in heart failure with preserved heart function
This study looks at how well doctors can assess fluid buildup before you leave the hospital if you have a type of heart failure called “preserved ejection fraction.” It may help improve decisions about when and how safely people are discharged.
Vandœuvre-lès-NancyAges 18 years+ - NCT04343443Recruiting
Test whether a lung ultrasound helps discharge planning after heart failure
This study looks at people hospitalized for worsening heart failure with weaker pumping (reduced ejection fraction). It tests whether a lung ultrasound evaluation near discharge can improve how doctors decide it is safe to send you home.
Vandœuvre-lès-NancyAges 18 years+ - NCT05983991Recruiting
Study of GATA2 gene changes over time
This study looks at how GATA2 gene changes affect your blood cells over time. It is for people of any age who have a GATA2 mutation they were born with, and it does not test a new drug—just collects information and samples during regular checkups.
AngersAges Any age - NCT07236177RecruitingEarly Phase 1
Enzyme test for early breast, lung, or pancreatic cancer
This study tests a new blood test that measures enzyme activity to detect localized cancer. It is for people with newly diagnosed, untreated breast, lung, or pancreatic cancer, as well as healthy volunteers.
PoitiersAges 18 years+ - NCT03622983Recruiting
Biobank study for pelvic cancers and endometriosis samples
This study collects and stores biological samples (like tissue or other lab samples) from people with pelvic gynecologic cancers or endometriosis, and links them with imaging/radiology information. It may help researchers learn more about these conditions and how they behave over time.
CréteilAges 18 years+ - NCT00899301Recruiting
Banking breast cancer and related tissue samples for future studies
This study collects and stores tissue and fluid samples from people with a breast lump or breast cancer so researchers can study cancer biology in the future. It may help future patients by allowing better lab tests and research on why breast cancer starts, grows, and comes back.
Nashville, TennesseeAges 18 years+ - NCT00898313Recruiting
Study looks for cancer clues in people at high risk for lung cancer
This study enrolls adults who are being checked for possible lung cancer because of concerning symptoms or a high-risk situation. It aims to find molecular (cell/DNA-related) predictors that may help doctors better recognize lung cancer earlier.
Nashville, TennesseeAges 18 years+ - NCT06854848Recruiting
Granulomatosis patient study with biological samples
This study collects medical data and biological samples from people diagnosed with systemic granulomatosis (a condition where tiny clumps of immune cells form in organs) to better understand the disease. It may help develop better treatments in the future.
BordeauxAges 18 years+ - NCT06237803Recruiting
Blood sample collection for plasma cell disorders
This study is collecting blood samples from people with plasma cell disorders to help researchers learn more about these conditions. It may be a good fit if you haven't started treatment yet and are willing to donate samples.
MelbourneAges 18 years+ - NCT00992303Recruiting
Collecting tissue samples during radiation for people with cancer
This study collects tissue samples from people with cancer while they are getting radiation therapy. It also includes healthy participants, to help researchers compare samples and better understand cancer and treatment.

Common questions
- Are there clinical trials studying Biological sampling?
- Yes. Clin2 currently lists 149 recruiting studies that include Biological sampling, 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 Biological sampling 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 Biological sampling 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 Biological sampling or a specific trial is right for you.
