Recruiting studies
- NCT03807128Recruiting
Study for multiple myeloma resistance and relapse changes
This study looks at how multiple myeloma (a bone marrow cancer) changes over time, especially why it becomes resistant to treatment or comes back. It may help researchers learn what drives relapse and could lead to better future treatments.

Testing MRI findings to find markers of brain blood vessel disease
This study looks at brain MRI scans in people with cerebral amyloid angiopathy (a condition where amyloid builds up in brain blood vessels). The goal is to search for “biomarkers,” or measurable scan features, to better understand and detect the disease in some people before symptoms or during symptoms.
Milan, MilanoAges 55 years+ - NCT04253015Recruiting
Safety registry for people with high-risk neuroblastoma on dinutuximab beta
This study is a long-term safety and follow-up registry. It tracks how dinutuximab beta is doing in real-world patients with high-risk neuroblastoma over time.

Testing brain-speech recordings during DBS for movement disorders
This study looks at how brain and speech networks work while people with Parkinson’s disease, essential tremor, or dystonia are getting deep brain stimulation (DBS). It may help doctors better understand and possibly improve speech outcomes for people receiving DBS.
Boston, MassachusettsAges 18–85 - NCT04323904Recruiting
Hantavirus registry for people with kidney or lung symptoms
This study is a registry, meaning it collects health information and possibly test results from people who have evidence of hantavirus infection along with specific illness symptoms. It may help researchers better understand how hantavirus affects the kidneys or the heart/lungs (and how to recognize it).
Cologne, North-Rhine WestfaliaAges Any age - NCT04342234Recruiting
Neural network tool to measure cleft palate from scans
This trial studies a computer “neural network” that uses existing dental impressions, scans, and photos to measure cleft palate features. The goal is to reduce the amount of repeated cleft lip and palate clinic work for patients and families.
BaselAges Any age - NCT04344912Recruiting
Study of COVID-19 effects on heart emergency care
This study looks at how the COVID-19 outbreak affected care for people admitted to the cardiac intensive care unit. It may help hospitals improve how they plan and respond during major outbreaks.
ParisAges 18 years+ - NCT04423484Recruiting
Treatment plan study for newly diagnosed one kidney tumor
This trial looks at what treatment recommendations work best for children with a nephroblastoma (Wilms tumor) that is in only one kidney and has not been treated yet. It may help doctors choose the best next steps for care while the child’s overall health supports treatment.
OuagadougouAges 6 months–18 years - NCT04477681Recruiting
Expanded access to cancer medicines for young people who need options
This trial helps children, teens, and young adults get an innovative cancer medicine when their disease has returned or hasn’t responded—and standard options are not available. It checks whether a “compassionate use” or off-label medicine plan can be carried out safely for the people who need it.
Villejuif, Val de MarneAges Up to 25 years - NCT04516720Recruiting
Build a database of brain and spinal cord tumor cases
This study builds a large medical database of people with primary brain or spinal cord tumors treated at the Montpellier Cancer Institute. It may help researchers understand patterns of care and outcomes, which can guide future research and treatment decisions.
Montpellier, HeraultAges 18 years+ - NCT04595630Recruiting
Testing heart blood markers to spot early bypass blockage
This study checks whether heart blood tests can predict early blockage of a coronary bypass graft soon after bypass surgery. It may help doctors identify patients at higher risk sooner so they can monitor or treat problems earlier.
ZagrebAges 18 years+ - NCT04695028Recruiting
Study to better understand crystal-related joint pain
This study looks at people with certain types of crystal deposits in joints (like gout, CPPD, or hydroxyapatite crystal disease). It uses scans such as ultrasound and a special CT-type scan called DECT to confirm and better understand what’s causing your symptoms.
LommeAges 18 years+ - NCT04781920Recruiting
Follow-up after ACL ligament surgery
This study is checking how people are doing after anterior cruciate ligament (ACL) reconstruction (a surgery to repair a knee ligament). It may help researchers understand recovery and long-term outcomes after ACL surgery.
Saint-EtienneAges 18 years+ - NCT04819893Recruiting
Study fatty acids and eye disease risk in newborns
This study looks at whether fatty acids from the mother are linked to the risk of retinopathy of prematurity, an eye condition that can affect very premature babies. It involves checking factors related to how the body responds to fatty acids during pregnancy and comparing mothers in different pregnancy situations.
DijonAges 18 years+ - NCT04829526Recruiting
Study of suspected Guillain-Barré syndrome cases
This is an observational study that looks at people who were suspected to have Guillain-Barré syndrome and were cared for at University Hospital of Basel in the past. It does not test a new treatment—researchers review existing care to learn more about this condition.
BaselAges 18 years+ - NCT04846712Recruiting
Ultrasound to check how severe a new ankle sprain is
This trial studies whether an ultrasound scan can help doctors judge how severe a first-time ankle sprain is. It may help guide treatment and follow-up for people whose sprain affects work or sports.
Saint-EtienneAges 18–60 - NCT04944030Recruiting
Study collects health data for metastatic lung cancer patients
This study collects medical information and test results from people with lung cancer that has spread (or cannot be cured with local treatment). It does not test a new drug; it helps researchers better understand patients’ health and care needs over time.
AngersAges 18 years+ - NCT04956185Recruiting
Collecting hospital data from people with stroke
This study collects information from people admitted to the stroke care team or neurology during their hospital stay. It may help improve stroke care by understanding patient conditions and hospital experiences.
Ghent, FlandersAges Any age - NCT04962815Recruiting
Study to collect brainwave data for ICU delirium
This study tests how well a special brain-monitor (EEG) can be used to assess delirium in people in the ICU. It may help improve delirium detection and monitoring in critically ill patients.
Stanford, CaliforniaAges 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+ - NCT05041387Recruiting
Collecting standard care data for nerve and muscle tests

Common questions
- Are there clinical trials for data collection?
- Yes. Clin2 currently lists 338 recruiting data collection studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a data collection trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a data collection trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
