Studying mood changes in inflammatory arthritis patients on biologics
This study looks at how mood disorders (like depression or anxiety) affect people with chronic inflammatory joint diseases when they use biologic medicines. It may help doctors understand which patients are at higher mood-risk and how to monitor them.
BesançonAges 18–80 - NCT04970459Recruiting
Collecting samples for Marfan and related conditions
This study collects biological samples and related health information for people with Marfan syndrome or similar inherited conditions. It helps researchers better understand these conditions and may lead to improved care for patients in the future.
ToulouseAges 3–99 - NCT06084195Recruiting
Study of ovarian cancer using advanced imaging
This trial uses a special imaging technique to study high-grade serous ovarian cancer. It aims to better understand the tumor to improve treatment. If you have advanced ovarian cancer and are scheduled for surgery, you may be eligible.

Study on kidney damage in children and adults with MGLS or FSGS
This trial collects medical data and blood/urine samples from patients with minimal change disease or focal segmental glomerulosclerosis (FSGS) to better understand how the immune system damages kidney cells.
NiceAges 1 year+ - NCT05343286Recruiting
Personalized exercise plan for older adults
This study looks for health “signals” that can help tailor a physical activity program for people aged 60 and older. It may help decide which exercise approach works best for different individuals over time.
NiceAges 60 years+ - NCT04214587Recruiting
Study of removed lung valves after treatment
This study looks at lung tissue taken out after a treatment that places a one-way lung valve to help breathing. They want to learn how the valve affects the airway and lung over time.
GroningenAges Any age - NCT05202210Recruiting
Biobank study for people with Noonan syndrome

ToulouseAges 18–99 - NCT07737509Recruiting
Understanding genetic factors in advanced solid tumor treatment
This study collects and analyzes tumor samples from people with advanced solid cancers to understand why some treatments work better than others and why resistance can develop. It aims to improve future treatments for patients like you.
SuttonAges 18 years+ - NCT03268668Recruiting

Common questions
- Are there clinical trials studying Biological samples?
- Yes. Clin2 currently lists 149 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.
