ToulouseAges 18–99 - 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+ - 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 - 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 - NCT04476563Recruiting
Study liver injury from checkpoint cancer immunotherapy
This study looks at why some people develop liver inflammation after checkpoint inhibitor cancer treatment, called checkpoint inhibitor–induced liver injury (ChILI). It compares people with ChILI to similar cancer patients who are starting the same type of immunotherapy, to better understand and track these liver injury events.
NottinghamAges 18 years+ - NCT04297085Recruiting
Study of why blood clots in veins come back
This study follows people who have had a vein blood clot (or related venous clot) to understand what factors may make the clot happen again. It may help clinicians find better ways to prevent repeat clots.
BrestAges Any age - NCT04207814Recruiting
Studying causes of repeated pregnancy loss in otherwise unexplained cases
This study looks for possible reasons why some pregnancies end in miscarriage or stillbirth when no clear cause is found. It involves tests and information from both partners, which may help guide future care for couples like yours.
BrestAges 18–40 - NCT04018118Recruiting
Study of the course of high eosinophil blood disease
This study follows people with long-term high eosinophils (a type of white blood cell) and related conditions to learn how the illness changes over time. It helps doctors understand patterns of organ involvement and outcomes, which may improve future care.
LilleAges Any age - NCT03541525Recruiting
Study on red blood cell-related diseases in families
This study looks at how red blood cells work in people who have a related condition—or who have family members with one. It may help researchers understand causes of these diseases and improve future care.
CotonouAges Any age - NCT00896935Recruiting
Donate cancer tissue and blood samples for research
This study lets people with cancer who are getting a procedure at the Arizona Cancer Center or University Medical Center contribute tissue or blood samples for research. Your samples help researchers learn about cancer and may support future studies.
Tucson, ArizonaAges 18 years+ - NCT01000883Recruiting
Biopsy study linking breast cancer tissue markers to treatment response
This study looks at breast cancer samples taken by biopsy to see how tissue “molecular markers” relate to how you respond to therapy and how the cancer behaves. It may help researchers better match future treatments to the biology of your tumor.
Chapel Hill, North CarolinaAges 18 years+ - NCT07024251Recruiting
Collecting biological samples for oral and maxillofacial research
This study collects leftover samples (like tissue, saliva, or blood) from routine dental visits or oral surgeries. The samples are used to learn more about mouth and jaw diseases, with no extra procedures needed.
Milan, ItalyAges 18 years+ - NCT06718894Recruiting
New treatment strategy for primary podocytopathies
This trial is testing a new treatment approach for people with certain kidney diseases called podocytopathies (like FSGS and MCD). It may help if you have active disease, even after a kidney transplant, or if you have another type of kidney inflammation.
MilanAges Any age - NCT00899626Recruiting
Collecting stool and tissue markers from people with bowel conditions
This study collects samples (like tissue and other body fluids) from people who are getting a colonoscopy or similar camera test. It aims to find “biomarkers,” which are measurable signals that may help doctors better understand or detect bowel problems such as colorectal cancer, polyps, or inflammatory bowel disease.
Nashville, TennesseeAges 18 years+ - NCT04458792Recruiting
Builds a cancer blood-and-biomarker database after sarcoma treatment
This study collects information and blood samples from adults with sarcoma who had surgery and possibly radiation. The goal is to build a large dataset that helps researchers understand sarcoma better and improve future care.
Montpellier, HeraultAges 18 years+ - NCT05089162Recruiting
Testing a heart ultrasound approach in chronic heart failure
This study looks at people with chronic heart failure with weaker pumping function and checks how well a lung/heart ultrasound can assess congestion (fluid buildup). If you qualify, you may help test a better way to evaluate your condition during a planned hospital visit.
Vandœuvre-lès-NancyAges 18 years+ - NCT04332692Recruiting
Check if a lung ultrasound helps evaluate discharge after heart failure
This study looks at whether doing lung ultrasounds can better assess people right before they leave the hospital after an acute heart failure flare. It may help doctors decide when someone is ready for discharge and tailor care to reduce risk after leaving.
Vandœuvre-lès-NancyAges 18 years+ - NCT05097898Recruiting
Check fluid buildup in heart failure with normal pumping
This study evaluates how well doctors can assess “fluid congestion” in people with chronic heart failure where the heart’s squeezing is still preserved. It may help improve how patients are monitored during hospital visits.
Vandœuvre-lès-NancyAges 18 years+ - NCT05089149Recruiting
Check how lung ultrasound helps manage heart failure congestion
This study looks at people with long-term worsening heart failure who are coming to the hospital for a planned visit, to see how checking “congestion” (fluid buildup) may guide care. It may help the team understand whether lung ultrasound can better assess who needs treatment changes.
Vandœuvre-lès-NancyAges 18 years+ - NCT07491354Recruiting
Predicting chronic pain after ICU trauma
This study looks at how biological, psychological, and social factors might help predict long-term pain after a traumatic injury that required ICU care. If you are an adult with a serious injury and at least one broken bone, you may be eligible.
MontpellierAges 18 years+ - NCT05775458Recruiting
Study of treatments for aggressive brain tumor cell damage
This study looks at glioblastoma (GBM), a very aggressive brain tumor, and how “brain cell overload” (glutamate excitotoxicity) may affect tumor growth. It focuses on adults who are planned for complete tumor removal, followed by standard radiation and chemotherapy.
