Test an immune marker in primary Sjögren’s disease activity
This study looks at an immune reaction (called anti-Ro/SSA IgE) to see how active primary Sjögren’s disease is. It may help doctors better understand what’s driving symptoms and activity levels over time.
BourgoinAges 18 years+ - NCT02861781Recruiting
Collecting body tissue samples during bariatric surgery
This study collects small tissue samples during planned weight-loss surgery to better understand metabolism and how insulin works in people with and without type 2 diabetes. You may help researchers by allowing their team to take these samples while you are already having surgery.
MontpellierAges 18–65 - NCT02878408Recruiting
Study of immune and genetics factors in bipolar or schizophrenia
This study looks at how the immune system, genetics, inflammation, and past exposures may relate to bipolar disorder or schizophrenia. It may help researchers understand the cause and find better ways to support people with these conditions.
Créteil, FranceAges 16 years+ - NCT03010124Recruiting
Biomarker testing in ovarian cancer to guide future treatment
This study looks at tumor tissue from ovarian cancer patients to find “biomarkers,” or lab signals, that may predict how the disease behaves or how it might respond to treatment. You may be asked for a biopsy of the relapsed (coming back) tumor or to use an existing archived tumor sample.
Villejuif, Val de MarneAges 18 years+ - NCT02474160Recruiting
Banking cancer tissue and blood for future research
This study collects and stores leftover or newly taken samples of tissue and blood from people with cancer. The goal is to build a research library that can help investigators study cancer and develop better tests or treatments.
Birmingham, AlabamaAges 2 months+ - NCT02534649Recruiting
Drug-matching trial for adults with cancer DNA changes
This trial looks for the specific DNA or tumor changes in your cancer and then matches you to a targeted drug plan. It’s meant for people with early cancer that has not already been treated in this study.
BayonneAges 18 years+ - NCT02530658Recruiting
Sequencing children’s tumor and normal tissue samples
This study collects children’s normal and tumor tissue (or blood-related normal samples) and reads their DNA/RNA to look at genetic information. It may help researchers understand cancer-related changes and improve future testing, even when the goal isn’t to treat you directly.
Memphis, TennesseeAges Any age - NCT02397824Recruiting
Teeth photo study for people with rare diseases
This study looks at how rare diseases can show up in the mouth and teeth, using pictures of your teeth. It may help doctors recognize dental signs earlier and better describe these rare conditions.
Strasbourg, AlsaceAges Any age - NCT02478892Recruiting
Screening study for pancreatic cancer in inherited gene risk
This trial tests ways to screen people who have a family-passed (inherited) gene mutation linked to higher pancreatic cancer risk. The goal is to find pancreatic cancer earlier and improve how screening is done for people at increased risk.
Philadelphia, PennsylvaniaAges 18 years+ - NCT01520844Recruiting
HIV cohort study comparing people on and off treatment
This study follows adults with HIV over time to compare different groups based on how stable their virus levels are. It may help researchers understand who can safely interrupt treatment and who should stay on it, and how immune health changes.

- Are there clinical trials studying Blood sampling?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood 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 Blood 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 Blood 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 Blood sampling or a specific trial is right for you.
