Recruiting studies
- NCT05595954Recruiting
Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.
BaselAges 65 years+ - NCT05577754RecruitingPhase 2
Trial tests alpelisib for MCAP with PIK3CA mutations
This Phase 2 study tests alpelisib in children and adults with MCAP, a condition caused by a specific PIK3CA gene mutation. The goal is to see if the treatment is effective and safe, while carefully monitoring blood sugar and organ function.
AmiensAges 2–40 - NCT03518099Recruiting
Testing blood signals after sudden bowel blood flow injury
This study is looking for signs in the body (called biomarkers) after sudden loss of blood flow to the intestines. It involves getting a CT scan to check what is happening in the abdomen so the researchers can see which signals match intestinal injury.
ClichyAges 18 years+ - NCT05494684Recruiting
Nature-based relaxation for children during blood tests
This study tests whether a nature-based activity can help children aged 5 to 9 feel calmer and less stressed during a blood draw. It aims to make the experience more comfortable for children with long-term illnesses.
OuluAges 5–9 - NCT04392401Recruiting
Study immune changes in adults during ICU stay for COVID-19
This study looks at how your immune system responds while you’re in the intensive care unit (ICU) for COVID-19. Researchers will collect samples early in the ICU stay to better understand immune changes during the illness.
BronAges 18 years+ - NCT05443087Recruiting
Checking blood levels of targeted drugs for digestive cancers
This trial monitors how your prescribed targeted cancer medicine moves through your body by doing extra blood tests. The goal is to understand the drug’s levels and dosing in people with advanced digestive cancers, so treatment can be better managed.
AmiensAges 18 years+ - NCT05448326Recruiting
Revisiting test results for children and adults without a diagnosis
This study re-checks earlier genetic testing for people who still do not have a diagnosis for a developmental or physical difference. It may offer new genetic testing (like genome sequencing) using new or stored samples to help find a cause when the first results were unclear or negative.
DijonAges Any age - 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+ - NCT05384392Recruiting
Blood and brain-marker study after a first psychotic episode
This study looks at whether special body and brain markers can predict how a person’s symptoms change over two years after a first psychotic episode. It may also help doctors understand who responds better to treatment, so future care can be more personalized.
AngersAges 15–30 - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Anchorage, AlaskaAges 40–75 - NCT05354765Recruiting
Collect immune cells by lymphapheresis to study cancer response
This trial studies how changing your immune system (with earlier treatments) affects cancer by collecting immune cells from your blood using a process called lymphapheresis. It may help researchers find better ways to monitor immune-related responses and side effects.
ParisAges 18 years+ - NCT05267379Recruiting
Study of causes of pancreatitis after ERCP
This study looks at how genes and medication processing in the body may relate to getting pancreatitis after an ERCP procedure. If you are having an ERCP and meet the criteria, your data and possibly samples may help researchers understand who is at higher risk.
Nijmegen, GelderlandAges 18 years+ - NCT05273138Recruiting
Study of skin immune and support cells in systemic sclerosis
This study looks at skin cells and immune cells in people with systemic sclerosis to better understand what drives the disease. Your participation may help researchers learn how the immune system and skin support cells change over time.
LilleAges 18 years+ - NCT05288842Recruiting
Study spinal fluid and brain changes in dementia types
This study looks at spinal fluid and MRI results in people with Alzheimer’s disease, frontotemporal dementia, or normal thinking (controls). It aims to understand differences in brain-related cells and measure what might help explain or track these conditions.
LilleAges 40–85 - NCT05263804Recruiting
Study uses MRI and blood clues after ischemic stroke
This study looks for biological and imaging markers that may predict heart/vascular outcomes after an ischemic stroke. You may join if you are eligible for standard stroke treatment and can complete planned follow-up and MRI scans.
BronAges 18 years+ - 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 - NCT04530890Recruiting
Testing blood tumor DNA in digestive and breast cancers
This study looks at a blood test for “circulating tumor DNA” (tiny pieces of cancer-related DNA in the blood). It may help doctors learn more about digestive, gynecologic, or breast cancers and how patients respond when treatment like chemotherapy or immunotherapy is needed.
PoitiersAges 18 years+ - NCT05191940Recruiting
Radiation for advanced pancreatic cancer you can’t remove by surgery
This trial studies how well radiation therapy works for pancreatic cancer that is locally advanced (near important blood vessels) and cannot be removed with surgery. It may help shrink or control the cancer when surgery isn’t an option.
Wiener Neustadt, Lower AustriaAges 18 years+ - NCT05156385Recruiting
Study of sexual problems in women with treated high blood pressure
This study looks at sexual dysfunction (sexual problems) in women who are being treated for high blood pressure. It may help researchers understand what causes these issues and what could improve them.
Toulouse, CHU de ToulouseAges 18 years+ - NCT05123443Recruiting

This study looks at how “iron rims” in brain MRI scans change over time in people with multiple sclerosis (MS). It may help researchers understand MS activity better and how iron changes relate to disease progression.
NottinghamAges 16 years+ - NCT05110937Recruiting
Testing immune cell changes in sepsis and trauma shock
This study looks at abnormal immune cells (from the bone marrow) in people with sepsis or severe trauma with shock. It aims to understand why the body’s immune response gets out of balance, which could help guide future treatments.
Gainesville, FloridaAges 18–100 - NCT05089747Recruiting

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