Fitzroy, VictoriaAges 18–90 - NCT05140265Recruiting
Uses EEG and medical records to build a privacy-protected database
This study creates a large, de-identified database by combining EEG test recordings with basic clinical information from medical records. It helps researchers use brain-wave data for future research while protecting your identity.
Albuquerque, New MexicoAges 18 years+ - NCT05151809Recruiting
Italy-wide database study for adults with primary biliary cholangitis
This study creates a national registry (database) of adults in Italy living with primary biliary cholangitis (PBC). Being included can help doctors better understand the condition and improve future care.
AnconaAges 18 years+ - NCT05257135Recruiting
Study database and blood samples for colon cancer cachexia
This study collects clinical information and planned blood samples to better understand “cachexia,” which is a serious wasting condition that can happen with advanced cancer. It may help doctors find better ways to predict and manage symptoms in people with colon cancer who can’t have surgery.
MontpellierAges 18 years+ - NCT05267041Recruiting
Lung cancer database study at Lyon hospitals
This study collects information about people who have been treated for lung or chest cancers at Lyon University Hospital. Your data may help researchers better understand these cancers and improve future care.
Pierre-BéniteAges 18 years+ - NCT05434026Recruiting
Colorectal cancer database study for people having surgery
This study enrolls people with colon cancer found on biopsy and who are able to have surgery. It mainly builds a medical database to help researchers understand care and outcomes, and it depends on you consenting to participate.
BeijingAges Any age - NCT05521503Recruiting
Collecting heart tissue samples for a shared research database
This trial builds a database by collecting and storing biopsy or biopsy-related samples from adults being evaluated for certain heart conditions. It may help researchers study heart disease and amyloidosis by making past tissue samples easier to access for future research.
Lexington, KentuckyAges 18 years+ - NCT05549635Recruiting
Database and blood sample registry for hypersensitivity pneumonitis
This trial is building a patient database and collection of samples from people with hypersensitivity pneumonitis (HP), a lung condition caused by breathing in an allergy-like trigger. Your information and samples may help researchers learn how HP is diagnosed and tracked over time.
Hellerup, CopenhagenAges 18 years+ - NCT05550675Recruiting
Study of bowel leakage patterns using rectal pressure tests
This trial builds a “database” to better understand why some people have stool (faecal) leakage versus double incontinence (urine plus stool). It asks about symptoms and performs a rectal pressure test to see which factors are linked to different types of leakage.
Brussels, Brussels CapitalAges 18 years+ - NCT05571774Recruiting
Building a database for severe ADAMTS13 deficiency
This trial is creating a research database for people with severe ADAMTS13 deficiency, a condition where the body has very low activity of a key blood-protein. It may help researchers better understand the condition by collecting and organizing patient information.
Suzhou, JiangsuAges Any age - NCT05588167Recruiting
Niemann-Pick type C patient database and genetic data study
This study collects health information and genetic samples from people diagnosed with Niemann-Pick disease type C. The goal is to build a large database that can help researchers better understand the condition and improve future care.
Bethesda, MarylandAges 3 months+ - NCT05618145Recruiting
Join a national study database for primary sclerosing cholangitis
This study creates a national database for people diagnosed with primary sclerosing cholangitis (PSC). It may help researchers learn more about the condition by collecting health information from participants.
AnconaAges 17 years+ - NCT05634928Recruiting
Database study for patients with blood clotting signs
This trial builds a database to study patterns in blood tests and blood smear findings that can suggest small blood clots in the body. Joining may help researchers learn how to recognize and track these changes over time.
Suzhou, JiangsuAges Any age - NCT05662293Recruiting
Study of heart muscle weakness caused by abnormal heart rhythms
This study looks at a condition where an abnormal heart rhythm can weaken the heart muscle (arrhythmia-induced cardiomyopathy). You may be asked questions, have heart tests reviewed, and help researchers better describe who is affected and how it develops.
BaselAges 18 years+ - NCT05676099Recruiting
TSC or LAM blood and health information registry

Common questions
- Are there clinical trials for database?
- Yes. Clin2 currently lists 203 recruiting database 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 database 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 database 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.
