Finding the best care for low blood before planned surgery
This study looks at how to detect and treat pre-surgery anemia (low hemoglobin/low blood level) in people having planned operations where blood transfusion is likely.

This study looks at how blood pressure changes over time in older adults with high blood pressure, and how it relates to frailty (a state of increased weakness). The goal is to learn more about managing blood pressure in older people.
MilanAges 75 years+ - NCT06790082RecruitingPhase 2
FAPI PET scan to diagnose pleural mesothelioma
This trial tests if a newer type of PET scan (FAPI PET) can better diagnose pleural mesothelioma than a standard FDG PET scan. If you have a suspicious spot in your lung lining and need a biopsy, this study may help improve how we find and track this cancer.
Aalborg, Region North JutlandAges 18 years+ - NCT06839833Recruiting
APOL1 gene test study for trial volunteers
This study checks if a new genetic test for the APOL1 gene works correctly. It uses samples from people who have already joined another drug trial.

Which advanced breast scan is better for you?
This study compares two advanced breast imaging methods—contrast-enhanced mammography (CEM) and breast MRI—to see which is better at finding cancer, especially in women with dense breasts or unclear mammogram results. If you are being referred for one of these exams, you may be able to join and help doctors learn which test works best.
NaplesAges 18 years+ - NCT06842615Recruiting
Testing a new blood test for cancer detection
This study checks if a new blood test (PanTum Detect) can find cancer or pre-cancer. It compares results in people who may have cancer and in healthy people, using a PET/CT scan as a reference. This could lead to a simpler way to detect cancer early.
BratislavaAges 18–88 - NCT06837064Enrolling by invitation
Can a chatbot help manage Irritable Bowel Syndrome?
This study tests whether a chatbot can help adults with Irritable Bowel Syndrome (IBS) manage their symptoms. If you have been diagnosed with IBS, you may be able to join and use the chatbot as part of your care.
MoscowAges 18 years+ - NCT06836089Enrolling by invitation
MRI study for dense breasts with a special imaging technique
This trial tests whether a type of MRI called Diffusion Weighted Imaging (DWI) can more accurately identify breast issues in women with dense breast tissue. If you have dense breasts and have already had a breast MRI with DWI, this study may help improve future diagnosis.
NaplesAges 40 years+ - NCT06828107Recruiting
Testing a device to detect traumatic brain injury
This study tests a new device called SENSE to see if it can detect traumatic brain injury (TBI) quickly. You may qualify if you have a TBI with bleeding seen on a CT scan, or if you are a healthy volunteer without brain problems.
Gainesville, FloridaAges 22 years+ - NCT06827366Recruiting
Lifestyle study for people at high risk of colorectal cancer
This study tests a lifestyle program for people who are at high risk for colorectal cancer but have not been diagnosed. The goal is to see if healthy changes can help lower your risk over one year.
Lyon, FranceAges 35–74 - NCT06827730Recruiting
Ultrasound for chest or belly pain in the ER
This study uses a quick bedside ultrasound (called PoCUS) to help doctors diagnose chest or belly pain in the emergency room. If you join, you'll get this ultrasound early in your visit to see if it helps find the cause of your pain faster and more accurately.
BrusselsAges 18 years+ - NCT06835244Enrolling by invitation
Study of PSMA PET/CT scans for non-prostate cancers
This study looks at how well a special scan (PSMA PET/CT) works for people with cancers other than prostate cancer. If your doctor already scheduled this scan for your care, you may be able to help researchers learn more about its accuracy.
BolognaAges 18 years+ - NCT06819917Recruiting
Liver fibrosis test study for fatty liver disease
This study is looking for new ways to detect liver scarring (fibrosis) in people with fatty liver disease (NAFLD, NASH, MASLD, or MASH). If you qualify, you will give a blood sample to help identify biomarkers that could replace biopsies.
CopenhagenAges 18–75 - NCT05033678Recruiting
Teledermoscopy and AI help review your skin spot images
This study tests a way for doctors to send clear images of your skin spot to be reviewed remotely using teledermoscopy (digital images of the skin). It may help speed up specialist input and improve how skin spots are assessed.
LundAges 15 years+ - NCT05782478Recruiting
Ultrasound test to guide care for sudden breathing trouble
This trial studies whether a quick bedside ultrasound exam (done in the emergency department) adds useful information when people arrive with sudden breathing difficulty. It may help clinicians choose the right next steps faster and safer.
Helsingborg, Skåne CountyAges 18 years+ - NCT06807983Recruiting
Lung and heart ultrasound for breathing trouble in older adults
This trial tests whether using lung and heart ultrasound (LuCUS) can help emergency doctors better diagnose and treat shortness of breath in patients over 65. It aims to improve care for older adults with severe breathing problems.
ToulouseAges 65 years+ - NCT06803628Recruiting
Ultrasound to rule out bowel blockage in ER

- How do I know if I qualify for a diagnostic 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 diagnostic 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.
