BeijingAges Any age - NCT04226534Recruiting
Join a study measuring effort in healthy trained people
This study builds a database by having healthy, trained volunteers do maximal effort physical tests while measuring how the body responds. It may help researchers better understand exercise performance and safety, though you’re likely not receiving a treatment for an illness.
BrusselsAges 18–65 - NCT03328611Recruiting
Joint replacement outcomes database for degenerative joint disease
This study collects information about people with “wear-and-tear” joint disease who need joint replacement. The goal is to better understand outcomes after surgery and improve future care.
Indianapolis, IndianaAges Any age - NCT04541862Recruiting
ICU patient information database for adults
This trial collects and studies health information from people who are critically ill and admitted to an intensive care unit. It may help doctors learn how to better care for ICU patients in the future.
TaipeiAges 20 years+ - NCT03521648Recruiting
BPH treatment safety and effectiveness data collection
This trial collects information from people being treated for enlarged prostate (BPH) and related urinary symptoms to evaluate how well treatments work and how safe they are. It may help improve future care by better tracking real-world outcomes.
Sankt Gallen, Canton of St. GallenAges 18 years+ - NCT04714957Recruiting
Personalized study for cancer spread in the belly lining
This trial studies people whose cancer has spread to the lining of the abdomen (the “belly lining”), including cancers from the digestive tract or ovaries. You may be asked to join because the study aims to learn how to better match care to different patterns of this belly lining cancer spread.
LyonAges 18 years+ - NCT03989323Recruiting
Register to track cancer immune therapy and side effects
This study sets up a real-world patient database to follow people starting cancer immunotherapy and record immune-related side effects. You may help doctors better understand who gets these side effects and how they change over time.
BronAges 18 years+ - NCT04613089Recruiting
Study of Batten disease progress and clinical changes over time
This trial tracks how Batten disease (NCL) affects the body and how symptoms change over time. If you have a confirmed genetic (molecular) diagnosis—especially CLN2 with Brineura treatment—it may help researchers understand disease patterns and care needs.
HamburgAges Any age - NCT02778724Recruiting
Heart catheterization registry for adults who had angioplasty
This study is a national registry that collects information from adults who had a heart catheter test (coronary angiogram) or a procedure to open blocked heart arteries (angioplasty). It helps doctors better understand how these procedures are used and what outcomes patients experience.
Le Coudray, Eure Et LoireAges 18 years+ - NCT03552926Recruiting
Biobank and scan database for recent small stroke patients
This study builds a database and collection (a biobank) from people who recently had a small stroke affecting deep brain areas. It may help researchers better understand small stroke patterns and support future care through better brain imaging and follow-up.
ParisAges 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 - 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 - NCT02784977Recruiting
Sleep apnea study using a national sleep database
This study collects information from adults who are getting a sleep test because obstructive sleep apnea is suspected. It helps researchers better understand sleep apnea and who develops it, without giving a new treatment.
IstanbulAges 18–80 - 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 - NCT04487340Recruiting
Online database for people with acute stroke care
This study sets up an online database to track people who have had a stroke soon after it happens. The goal is to understand and improve how stroke care quality is evaluated.

Common questions
- Are there clinical trials for database?
- Yes. Clin2 currently lists 195 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.
