Inhaled amikacin to prevent pneumonia in cirrhosis patients on ventilators
This trial tests whether inhaling an antibiotic called amikacin can prevent ventilator-associated pneumonia in patients with severe liver disease (cirrhosis) who are on a breathing machine. If you or your loved one is in the ICU with liver issues and needs a ventilator, this study may help reduce the risk of a serious lung infection.

Fecal transplant and diet for new ulcerative colitis
This study tests whether a combination of fecal transplant (transferring healthy stool into your gut) and dietary changes can help control inflammation in people recently diagnosed with active ulcerative colitis. It may offer a new treatment option before starting stronger medications.
Kochi, KeralaAges 18–75 - NCT06890650Recruiting
Fecal transplant and diet for new Crohn's disease
This study tests whether a combination of fecal transplant (transferring healthy bacteria from a donor) and dietary changes can help control disease activity in people newly diagnosed with Crohn's. It is for those with mild to moderate symptoms who have not yet taken any Crohn's medications.
Kochi, KeralaAges 18–75 - NCT07222943Recruiting
Guided Imagery App for Kids with Stomach Pain
This study tests a mobile app that uses guided imagery (a relaxation technique using your imagination) to help children ages 7–12 with stomach pain disorders. The goal is to see if the app is easy to use and helpful for managing pain.
Austin, TexasAges 7–12 - NCT07226154Recruiting
Predicting chemo response in pancreatic cancer
This study looks at blood samples to see if we can predict how well pancreatic cancer responds to chemotherapy before surgery. It aims to help doctors choose the best treatment for each patient.
Duarte, CaliforniaAges 18 years+ - NCT07225309Recruiting
Meaning-Centered Therapy for Mexican Adults with Advanced Cancer
This study tests a therapy program called Meaning-Centered Therapy designed to help adults in Mexico with advanced cancer find meaning and improve their well-being. It involves sessions delivered by trained providers at the National Cancer Institute in Mexico (INCan).
New York, New YorkAges 18 years+ - NCT07224815Recruiting
DNA markers to predict chemo response in advanced colon cancer
This study uses a blood test to look for specific DNA changes that may help predict how well chemotherapy works in people with metastatic colorectal cancer. The goal is to find markers that could guide future treatment decisions.
Duarte, CaliforniaAges 18 years+ - NCT07222527Recruiting
One stent versus two for gallbladder problems
This trial tests whether using one plastic stent or two is better for people with gallbladder disease who need an ERCP but can't have gallbladder surgery right away. It aims to find which approach works best to keep the bile duct open and prevent complications.
Rochester, MinnesotaAges 18–95 - NCT07225114RecruitingPhase 2
Better ultrasound imaging with contrast before biopsy
This trial tests a new, detailed ultrasound technique that uses a contrast agent (called Definity) to get clearer images of a suspicious area before a biopsy. It may help doctors better see the blood flow in the lesion, which could improve diagnosis.
Chapel Hill, North CarolinaAges 18 years+ - NCT07224750Recruiting
A blood test to find early signs of gastrointestinal cancer
This study is testing a blood-based test to detect unique molecules (called miRNAs) that may signal the presence of several types of gut or digestive system cancers. The goal is to develop a simple screening tool that could catch these cancers earlier.
Duarte, CaliforniaAges 18 years+ - NCT07223307RecruitingPhase 2
MRI-guided radiation for liver cancers
This trial tests a precise MRI-guided radiation treatment for liver cancers, including liver cancer, bile duct cancer, or cancer that has spread to the liver. The goal is to target tumors more accurately while protecting healthy tissue.
Palo Alto, CaliforniaAges 18 years+ - NCT07223424RecruitingPhase 2
Patient preference study: shot vs infusion for immunotherapy
This study compares two ways to take immunotherapy drugs (nivolumab or pembrolizumab): as a shot under the skin (subcutaneous) versus an infusion into a vein (intravenous). It looks at which method patients prefer and is for people with certain advanced cancers where these drugs are already approved.

Study of 177Lu-CTR-FAPI for advanced solid tumors
This trial tests a radioactive drug called 177Lu-CTR-FAPI for people with advanced solid tumors that have not responded to standard treatments. It targets tumors that show a specific protein (FAP) on PET scans. The study focuses on certain cancers like pancreatic, breast, and soft tissue sarcoma.
ShanghaiAges 18–85 - NCT07226115Recruiting
Predicting chemotherapy outcomes for colorectal cancer
