Recruiting studies
- 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+ - NCT04413331Recruiting
Study follows adults with vasculitis over time
This observational study follows adults with vasculitis (inflammation of blood vessels) during an active flare or relapse. It aims to better understand how the disease changes over time and may help researchers plan future treatments.
ParisAges 18 years+ - NCT04698421Recruiting
Blood and tissue sample collection for rare autoimmune nerve diseases
This study collects biological samples (like blood or other specimens) from people with rare neurological conditions that may involve the immune system. Your samples may help researchers better understand these diseases.
ToulouseAges 6–99 - NCT04706481Recruiting
Use of stored, de-identified samples for research
This trial is for people who already agreed to let researchers use their stored biological samples and medical information that has been removed of personal identifiers. It may help future studies by allowing researchers to analyze existing samples without using new samples from you.
Hong KongAges Any age - NCT04804878Recruiting
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+ - NCT04873492Recruiting
Study how genes and blood signals relate to MS outcomes
This study looks at genetic information and blood test signals to understand why some people with early MS develop a worse outcome. It may help doctors predict who is at higher risk and better understand disease mechanisms.
Nantes, Loire-AtlantiqueAges 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+ - 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+ - NCT05198661Recruiting
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 - NCT05318196Recruiting
Predict kidney disease risk and progression from patient data
This trial looks at ways to predict how kidney disease may develop, change, or cause complications using information from patients. It may help doctors identify people at higher risk and tailor care earlier.
ToulouseAges 18–99 - NCT05370079Recruiting
Control group for people with specific serious illnesses
This trial includes a “control” group of people with certain diseases to compare outcomes against another group. If you qualify, you may receive the standard approach used in usual care rather than the experimental treatment.
BronAges 18 years+ - NCT05429138Recruiting
Tracking egg and sperm changes during melanoma treatment
This study measures how anti-cancer treatment affects a person’s egg reserve (for women) or semen quality (for men) over time. It may help doctors better understand fertility-related side effects of melanoma therapy and how they evolve during routine treatment.
BordeauxAges 18–45 - NCT05536388Recruiting
Study of a new drug for GBA-related Parkinson’s
This study is looking for ways to find new drugs that may help people with Parkinson’s caused by changes in the GBA gene. It may also include people with Gaucher disease and healthy volunteers, using blood and possibly skin samples.
New York, New YorkAges 18 years+ - NCT05666739Recruiting
Store your sample for future research studies
This study collects and stores your biological samples so researchers can use them for future environmental health questions. You might join if you’re an adult, can travel for visits, and agree to have your samples stored for later use.
Research Triangle Park, North CarolinaAges 18–100 - NCT05767203Recruiting
Study genetic and blood markers in people with inherited intellectual disability
This study looks at genetic-related and blood/biologic markers in people with an inherited (genetic) intellectual disability. The goal is to better understand these differences and how they might relate to the condition.
ParisAges Any age - NCT05767216Recruiting
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 - NCT05787795Recruiting
Studying early risk signs for multiple sclerosis
This study looks at people who are at higher risk for multiple sclerosis (MS), to better understand early changes before MS is diagnosed. It may help doctors identify who is more likely to develop MS and how to monitor them sooner.
North Haven, ConnecticutAges 18 years+ - NCT05924074Recruiting
Study of ferroptosis therapy in blood disorders with SF3B1 mutation
This study looks at ferroptosis (a type of cell stress that can affect blood-forming cells) in people with certain blood disorders linked to an SF3B1 gene change. It may help researchers understand whether targeting this pathway could improve outcomes.
PessacAges 18 years+ - NCT05968053Recruiting
Testing microplastics detection in neurosurgery patients
This study checks whether microplastics and nanoplastics can be detected in people undergoing neurosurgery. If it works, it could help doctors better understand possible material exposures around brain and nerve procedures.

EEG brain test for young people at risk of psychosis
This study uses a short EEG recording to look at brain activity patterns in young people with early signs of mental health conditions, including those at risk for psychosis, first episode psychosis, depression, or autism. It aims to find brain markers that could help identify people who might benefit from early 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.
