HRS-4642 plus AG before and after surgery for pancreatic cancer
This trial tests a combination of two medications (HRS-4642 and AG) given before and after surgery for pancreatic cancer that can be removed. The goal is to see if this treatment helps prevent the cancer from coming back.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06587841Recruiting
Spinal cord stimulation for early spinal cord injury
This study tests a noninvasive spinal cord stimulation device for people with recent or long-term spinal cord injury. It aims to improve bladder function and is conducted in British Columbia, Canada, and Ukraine.
Vancouver, British ColumbiaAges 19–65 - NCT06587828Recruiting
Looking at immune cells in people with autoimmune disease
This study collects blood, tissue, and other samples from people with autoimmune diseases like Crohn's disease, multiple sclerosis, or lupus. Researchers will study your immune cells (T cells) to learn what they are attacking, which could lead to better treatments in the future.
Orange, CaliforniaAges 18 years+ - NCT06588699RecruitingPhase 2
Digoxin for NASH liver disease study
This trial tests if the heart medication digoxin can help people with NASH (fatty liver disease with inflammation), who have moderate liver scarring. You will receive digoxin or a placebo for 24 weeks and have a liver biopsy before and after treatment to see if the medication reduces liver damage.
New Haven, ConnecticutAges 18–75 - NCT06589388Recruiting
Using a blood test to predict rectal cancer treatment success
This trial is looking at whether a simple blood test (ctDNA monitoring) can help predict how well total neoadjuvant therapy (chemo and radiation before surgery) works for rectal cancer. It may help doctors tailor treatment to your specific needs.
Ho Chi Minh CityAges 18–80 - NCT06589830RecruitingPhase 2
TL938 with Trastuzumab for HER2+ Colorectal Cancer
This trial is testing a new combination of drugs (TL938 and trastuzumab) for people with a specific type of advanced colorectal cancer that is HER2-positive and RAS wild-type. It may offer a new option if you have already tried standard chemotherapy and a blood vessel-blocking drug.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06590142Recruiting
Studying bowel tissue for future Hirschsprung's treatments
This trial collects leftover intestine tissue from children having bowel surgery to help develop future treatments using a child's own cells. It aims to find better ways to repair the bowel without needing donor tissue.
Liverpool, MerseysideAges birth–15 years - NCT06590246RecruitingPhase 1/Phase 2
Study of C-CAR031 for advanced GPC3-positive liver cancer
This trial tests a new type of cell therapy called C-CAR031, which is designed to target and attack liver cancer cells that have a protein called GPC3. It is for people with advanced liver cancer who have already tried other treatments and are looking for a new option.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06590948Recruiting
Using ultrasound features to classify liver nodules
This trial looks at whether special features seen on contrast-enhanced ultrasound can help doctors better classify liver nodules using a system called LI-RADS. It’s for people at high risk for liver cancer who have recent imaging and clear tissue diagnosis.
Hangzhou, ZhejiangAges 18 years+ - NCT06591169Recruiting
Lifestyle changes for PCOS, sleep apnea, and fatty liver
