Testing stool and bacteria clues for poor rectal cancer response
This study looks at stool samples to see whether gut bacteria or other microbes help explain why some rectal cancers respond less well to treatment given before surgery. If you have mid or lower rectal cancer and are planning pre-surgery treatment, your information and stool sample may help researchers improve how treatment is chosen.

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+ - NCT04690972Recruiting
Collection of blood and tissue samples for liver disease research
This study builds a research library of biological samples (like tissue and blood) from people with chronic liver disease. It aims to create better lab and preclinical models of tumors and long-term liver problems, which may help future treatments.
StrasbourgAges 18 years+ - NCT05202210Recruiting
Biobank study for people with Noonan syndrome
This study collects biological samples to better understand what causes Noonan syndrome. If you qualify, your participation could help researchers learn how the condition works and guide future care.
ToulouseAges 18–99 - NCT05251415Recruiting
Study of rare autoimmune diseases with blood and medical samples
This trial collects clinical and lab information (like blood and medical history) from people with rare autoimmune diseases, especially when symptoms are unusual. It aims to better understand what causes these illnesses and how newer treatments may help.
ToulouseAges 6–99 - NCT05936333Recruiting
Study why repeated pregnancy problems happen in some cases
This study looks at how the immune system may contribute to ongoing placenta inflammation in certain pregnancy histories. It may help researchers better understand causes behind pregnancy loss and related placental complications, using past placenta/tissue samples.
ClamartAges 18 years+ - NCT06197152Recruiting
RSV severity markers in hospitalized adults
This study looks for markers in the blood that can tell how serious an RSV infection might become. If you are hospitalized with RSV and have breathing symptoms, this trial will follow your recovery and test for clues about your illness.
CréteilAges 18 years+ - NCT06387654Recruiting
Collection of skin samples for immune-related skin diseases
This study collects skin samples and medical information from people with skin conditions caused by their immune system. It helps researchers better understand these diseases and develop new treatments.
ToulouseAges 6–99 - NCT06464159Recruiting

Common questions
- Are there clinical trials studying Biological collection?
- Yes. Clin2 currently lists 112 recruiting studies that include Biological 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 Biological 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 Biological 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 Biological collection or a specific trial is right for you.
