Testing abemaciclib plus 5-FU for advanced colorectal cancer
This trial is testing whether adding a targeted drug called abemaciclib to the standard chemotherapy 5-FU can help people with a specific type of advanced colorectal cancer (MSS) that has stopped responding to other treatments. The goal is to see if this combination is safe and effective.
Irvine, CaliforniaAges 18 years+ - NCT06654752Recruiting
Simpler treatment for lung flare-ups in kids with CF
This study tests a streamlined approach to managing sudden lung symptoms (pulmonary exacerbations) in children with cystic fibrosis. It aims to see if a simpler treatment plan works as well as standard care, which could mean less time in the hospital and fewer disruptions to daily life.
Birmingham, AlabamaAges 3–18 - NCT06655051Recruiting
Plastic versus metal stent for bile duct blockage from chronic pancreatitis
This study compares two types of stents (plastic vs. metal) to see which works better for treating bile duct narrowing caused by chronic pancreatitis. If you have a bile duct blockage from chronic pancreatitis, you may be eligible.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06655233Recruiting
Exploring gut bacteria in pancreatic cancer tumors
This trial studies bacteria found inside pancreatic tumors to see if they can help diagnose or predict the course of the disease. You may be eligible if you have a suspected pancreatic cancer and need a special biopsy (EUS-FNB).
Hunan, HunanAges 18–80 - NCT06655246RecruitingPhase 1
Ziftomenib and imatinib for advanced GIST
This trial tests a new drug, ziftomenib, combined with imatinib for people with advanced or spreading gastrointestinal stromal tumors (GIST) that have a KIT mutation. It may help if your GIST has gotten worse while on imatinib.
Birmingham, AlabamaAges 18 years+ - NCT06655415Recruiting
Study for family members at risk of inflammatory bowel disease
This study follows people who have a parent, sibling, or child with Crohn's disease or ulcerative colitis to help understand why some family members develop the condition. If you are 14 or older and do not already have IBD, you may be able to join.
Boston, MassachusettsAges 14 years+ - NCT06656299Recruiting
Nerve block for gallbladder removal surgery
This study tests a nerve block called EOIB to see if it helps reduce pain after gallbladder removal surgery. If you are having planned gallbladder surgery, this might be a good option for you.
IstanbulAges 18–65 - NCT06657144RecruitingPhase 1
Study of CHS-114 and toripalimab for advanced solid tumors
This study tests a new drug combo (CHS-114 + toripalimab) for people with advanced solid tumors like stomach, esophageal, or colorectal cancer that have already been treated. It aims to see if adding these drugs can help control the cancer better.
Tucson, ArizonaAges 18 years+ - NCT06658782Recruiting
MRI vs ultrasound for liver cancer detection in high-risk people
This trial compares two types of scans to see which detects liver cancer better in people at high risk. You would receive either an MRI with contrast or an ultrasound every 6 months to monitor for liver cancer.
Oxford, OxonAges 18 years+ - NCT06659588Recruiting
Study of chronic hepatitis risk in people with immune weaknesses
This study looks at people with certain immune system weaknesses to see if they are at risk for chronic hepatitis caused by a virus in the gut. Researchers want to understand how the immune system affects this infection.
ParisAges Any age - NCT06660576Recruiting
Gallbladder stones in children: causes and treatment
This trial studies gallbladder stones in children to understand what causes them. It looks at different types of stones and how they relate to conditions like hemolytic anemia, and helps guide treatment decisions.
SohagAges Up to 18 years - NCT06660693RecruitingPhase 3
Comparing rescue treatments for severe ulcerative colitis flare
This trial tests two different medicines, infliximab and upadacitinib, to see which works better for people with severe ulcerative colitis that hasn't improved after 3 days of IV steroids. The goal is to find the best rescue option to help you feel better and avoid surgery.

Nal-IRI chemo with immunotherapy and radiation for pancreatic cancer
This trial tests a combination of chemotherapy (Nal-IRI, 5-FU, leucovorin), an immunotherapy drug (PD-L1 inhibitor), and a targeted anti-angiogenic pill, with or without radiation (SBRT), as a second-line treatment for people with metastatic pancreatic cancer that has progressed after first-line therapy.
Nanjing, JiangsuAges 18–75 - NCT06662110Recruiting
Blood test to predict chemo and immunotherapy response in stomach cancer
