Recruiting studies
- NCT00897117Recruiting
Providing tumor tissue samples during lung cancer surgery
This study collects and analyzes tumor tissue from people with early-stage non-small cell lung cancer who are planning surgery. It may help researchers learn more about the cancer by studying samples taken at the time of your operation.
Nashville, TennesseeAges 18–120 - NCT01137643Recruiting

Cancer care program for adults to help manage cancer
This study is a general cancer care program for adults (and in some cases people at risk for cancer). It aims to improve how cancer care is organized and delivered, and you may benefit from extra care support through the program.
Atlanta, GeorgiaAges 18 years+ - NCT04917705Recruiting
Blood and tissue tests to find markers in muscle and skin disease
This study looks for blood and tissue “biomarkers” (measurable clues in samples) to help diagnose and predict outcomes in inflammatory muscle diseases and systemic sclerosis (a skin/organ condition). If you’re being evaluated for myopathy or early scleroderma, it may help doctors sort out the cause and follow your health more closely.
Strasbourg, Bas-RhinAges 18 years+ - NCT04837339Recruiting
Testing markers to predict problems after lung transplant
This study looks for lab “clues” that can help predict how well someone’s lungs will do after a lung transplant. It may help doctors spot transplant-related problems earlier so care can be planned sooner.

Study of genetic and epigenetic differences in twin pairs with Down syndrome
This study looks at how genetics and gene-regulation (how genes turn on and off) differ between close family members who have different Down syndrome status. Researchers hope the findings will help explain why Down syndrome outcomes can vary even in very closely related people.
ParisAges 4–11 - NCT06078098Recruiting
Autoimmune Hepatitis Database and Biobank Study
This study is building a database and collection of samples from people with autoimmune hepatitis in Italy. It aims to learn more about the disease and improve care.

Blood or spinal fluid study in autoimmune brain disorders
This study collects information from people with autoimmune encephalitis or related nerve/brain disorders, using blood and sometimes spinal fluid. It helps researchers better understand these conditions, which may guide future diagnosis and treatments.
Pointe à Pitre, GuadeloupeAges Any age - NCT06372054Recruiting
Predicting health risks for Italian Air Force members
This study aims to develop smart risk models using your body's data (like proteins and genes) along with personal exposure readings. It will help predict health risks for Italian Air Force personnel. You will wear a monitor and give samples, then be followed over time.
MilanAges 26–38 - NCT06391671Recruiting
Stress and Weight in Teens: A Personalized Nutrition Study
This study looks at how stress and weight are linked in teenagers. It uses a blood test to find patterns that could lead to personalized nutrition advice. If you join, you'll help researchers understand how your body handles stress and food.
Ghent, Oost-VlaanderenAges 11–17 - NCT04359394Recruiting
Rare severe pustular psoriasis family DNA study network
This study builds a large international registry of people with rare, severe pustular psoriasis to help doctors understand the genetics of the condition. You may be asked for information and, if you have eligible family members, DNA testing to learn how the disease runs in families.
MünchenAges 6 months+ - NCT07828665Recruiting
Building a gut tissue model to study infections
This study uses leftover, healthy tissue from a part of the small intestine (the duodenum) that is removed during surgery. The goal is to grow this tissue in the lab to better understand how infections affect the gut, which could help develop new treatments.
Negrar, VeronaAges 18 years+ - NCT07718841Recruiting
Blood test monitoring for early-stage breast cancer
This study uses a simple blood test called liquid biopsy to monitor cancer DNA in people with early-stage breast cancer before and during treatment. The goal is to see if this test can help guide treatment and improve outcomes.
San Sebastián, GuipúzcoaAges 18 years+ - NCT06724536Recruiting
Study of gut bacteria and TKIs in chronic myeloid leukemia
This trial looks at how gut bacteria affect the way chronic myeloid leukemia (CML) patients respond to tyrosine kinase inhibitor (TKI) medications. It may help doctors understand why some people have better outcomes than others.
TorinoAges 18 years+ - NCT07500324Recruiting
Searching for new markers in age-related eye diseases
This study looks for proteins in the blood and eye fluids that may help doctors better understand and monitor three common eye conditions: age-related macular degeneration, diabetic retinopathy, and retinal detachment. If you have one of these conditions, or if you are a healthy control with no retinal disease, you may be able to help by giving a small sample of blood or fluid from your eye during a routine procedure.
Roma, ItalyAges 18 years+ - NCT07494201Recruiting

Common questions
- Are there clinical trials studying Biological samples?
- Yes. Clin2 currently lists 146 recruiting studies that include Biological 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 Biological 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 Biological 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 Biological samples or a specific trial is right for you.
