Clermont-FerrandAges 18 years+ - NCT06525571RecruitingPhase 3
Blue light surgery for high-risk bladder cancer
This trial tests if using blue light during surgery helps remove all cancer in people with high-risk non-muscle invasive bladder cancer. It may lower the chance of the cancer coming back.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06515821Recruiting
Improving colorectal cancer screening and diagnosis
This study collects data to improve how colorectal cancer is found and diagnosed. It compares new testing methods (like breath and stool tests) with standard colonoscopy in people with and without cancer or risk factors.
SofiaAges 18 years+ - NCT06510894Recruiting
Testing a drug to improve heart imaging
This study tests if a drug can help suppress sugar uptake in the heart for clearer imaging. It may help researchers understand how to better see heart problems.
Philadelphia, PennsylvaniaAges Any age - NCT06482463Recruiting
D-lactate test for meningitis in patients with a brain drain
This study checks if a substance called D-lactate in the fluid around your brain can help diagnose meningitis that develops in the hospital after a brain drain (ventriculostomy). It aims to improve diagnosis.
ToulouseAges 18 years+ - NCT06222372Recruiting
New approaches for leprosy diagnosis and treatment
This study looks at new ways to diagnose and treat leprosy. It includes patients with a more serious form of leprosy and the people who live closely with them, to help stop the spread of the disease.
NilphamariAges 5 years+ - NCT06474806RecruitingPhase 2
PET scan for untreated prostate cancer
This trial tests a new type of PET scan that looks for a protein called uPAR on prostate cancer cells. It might help doctors see your cancer more clearly without needing surgery or treatment first.
Herlev, CopenhagenAges 18 years+ - NCT06475560Recruiting
Camera capsule endoscopy for colorectal disease diagnosis
This trial tests a camera pill (capsule endoscopy) as an alternative to a regular colonoscopy for people with colon or rectum symptoms. It's a simpler way to look inside your large intestine without a tube.
Odense CAges 18 years+ - NCT06440850RecruitingPhase 2
Targeted therapy for high-risk BRAF-mutated thyroid cancer
This trial tests two targeted drugs, vemurafenib and cobimetinib, for people with high-risk thyroid cancer that has a specific BRAF V600E mutation. The goal is to see if this combination can help prevent the cancer from coming back after surgery or other initial treatments.
Duarte, CaliforniaAges 18 years+ - NCT06454383RecruitingPhase 1
Gemcitabine and leflunomide for advanced pancreatic cancer
This trial tests if adding leflunomide (a drug used for arthritis) to standard chemotherapy (gemcitabine) can help people with advanced pancreatic cancer that cannot be removed by surgery. The goal is to see if the combination works better than gemcitabine alone.
Duarte, CaliforniaAges 18 years+ - NCT06420960Recruiting
Watch ECG vs. Holter for palpitations
This trial tests whether a special smartwatch can record heart rhythm during palpitations as well as a traditional Holter monitor. If you have unexplained palpitations and are willing to wear the watch, your participation could help doctors find better ways to diagnose heart rhythm issues.
GleizéAges 18 years+ - NCT06439810Recruiting
