Beijing, Beijing MunicipalityAges 18–75 - NCT05057845RecruitingPhase 2
Freezing treatment plus immunotherapy and a pill for liver cancer
This trial tests whether freezing (cryoablation) combined with tislelizumab and lenvatinib can help shrink advanced liver cancer and improve outcomes after earlier treatments stopped working or caused side effects. It may be an option if your cancer can’t be removed with surgery and you’ve already tried one prior systemic (whole-body) treatment.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04794582Recruiting
Preventing a belly hernia after first kidney transplant
This trial looks at ways to prevent an incisional hernia (a bulge at the surgical scar) after your first kidney transplant. If you’re getting a first transplant, joining could help test treatments or strategies that lower this post-surgery complication.
MadridAges 18 years+ - NCT05244278Recruiting
AI tool that helps find and classify colon polyps during colonoscopy
This trial tests an artificial-intelligence (AI) software tool that helps doctors spot and categorize polyps in real time during a colonoscopy. It may help improve how accurately and quickly polyps are detected during routine and medical colon exams.
Montreal, QuebecAges 45–89 - NCT05071131Recruiting
Inulin supplement to improve gut health in kidney disease
This trial studies whether taking inulin—a dietary fiber—can improve gut bacteria and the gut barrier in people with end-stage kidney disease on hemodialysis. It may help reduce gut-related problems that can affect overall health in kidney disease.
BerlinAges 18–75 - NCT04998552Recruiting
CyberKnife radiation for certain pancreatic cancer patients after chemotherapy
This trial studies how safe CyberKnife is when used to treat some borderline resectable or locally advanced pancreatic cancers after chemotherapy. It may help patients by targeting the tumor with precise radiation, while researchers closely watch for side effects.
Pennington, New JerseyAges 18 years+ - NCT04991948RecruitingPhase 1
Testing pembrolizumab after CYAD-101 plus FOLFOX in colon cancer
This early-phase study tests whether adding pembrolizumab after CYAD-101 and FOLFOX chemotherapy can help treat metastatic colon or rectal cancer. It is mainly looking for safety and signs of how well the treatment works in people whose cancer has not responded to prior therapy.
Jacksonville, FloridaAges 18 years+ - NCT05043688RecruitingPhase 3
Camrelizumab with chemo before surgery versus chemo-radiation
This Phase 3 trial compares two ways of treating resectable esophageal squamous cell cancer: (1) camrelizumab plus chemotherapy before surgery versus (2) chemo-radiation. It aims to see whether adding camrelizumab before surgery can improve outcomes for people who are planned to have their tumor surgically removed.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04900597Recruiting
Testing blended tube feeds on kids’ stomach function
This study compares how “blended” tube feeds affect stomach and upper digestive function in children who use a feeding tube. It may help doctors understand whether blended feeds change digestion in ways that matter for comfort and physiology.
Boston, MassachusettsAges 1 year+ - NCT05124886Recruiting
Study gut–kidney link in people with bowel or stone problems
This study looks at how problems in the gut can lead to kidney stone risk, especially in people with inflammatory bowel disease or after certain weight-loss surgery. Your participation may help researchers understand the gut–kidney connection and identify why stones happen.
New York, New YorkAges 18–80 - NCT05056220RecruitingPhase 3
Albumin treatment for advanced cirrhosis with fluid buildup
This trial tests whether a personalized long-term albumin (a blood protein medicine) can help people with advanced liver scarring who have fluid in the belly (ascites). It compares the personalized albumin approach to standard care to see if it improves outcomes over time.
LeuvenAges 18 years+ - NCT05057052RecruitingPhase 2
Freezing liver tumors with immunotherapy and a pill drug
This Phase 2 trial tests whether freezing (cryoablation) plus sintilimab (an immune system medicine) and regorafenib (a pill) can shrink colorectal cancer that has spread to the liver. It is for people whose cancer has come back or progressed after at least two prior chemotherapy treatments.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05224960RecruitingPhase 2
Stem cell treatment for worsening liver cirrhosis
This trial tests umbilical-cord stem cells to see if they can improve outcomes in people with decompensated (worsening) cirrhosis. You may be considered if your liver disease is moderate to severe (MELD 15–30) and you do not have certain high-risk problems right now.
Lanzhou, GansuAges 18–75 - NCT05246657Recruiting
EUS procedure to bypass blocked bile ducts when ERCP fails
This trial studies a new way to access the bile ducts using a scope guided by ultrasound when standard ERCP can’t be done or doesn’t work. It may help people with non-cancer (benign) bile duct blockages get the bile flowing again.
ValladolidAges 18 years+ - NCT05235867Recruiting
Secretin to help teens with anorexia during refeeding
This trial studies whether secretin can help the body during “refeeding,” the careful process of restarting nutrition in people hospitalized for restrictive-type anorexia nervosa. It compares participants with very high vs very low urine output during refeeding to see if responses differ.
Los Angeles, CaliforniaAges 13–24 - NCT05252754RecruitingPhase 3
Medicines to prevent pancreas swelling after ERCP
This Phase 3 study tests whether putting an anti-inflammatory medicine into the rectum (indomethacin) plus taking an immune-suppressing pill (tacrolimus) works better than using the two medicines in a different combination to prevent pancreatitis after an ERCP procedure. If you qualify, you may be assigned to one of the treatment options to lower your risk of post-ERCP pancreas inflammation.
Baltimore, MarylandAges 18 years+ - NCT05248581Recruiting
Living donor liver transplant for unresectable colon cancer spread
This trial looks at using a living donor liver transplant for people whose colon or rectal cancer has spread to the liver in a way that can’t be removed with standard surgery. It may help if you might otherwise have limited options because your liver surgery would be too risky.
Rochester, New YorkAges 18 years+ - NCT04996914Recruiting
Radiation after chemo-embolization for liver cancer patients
This trial studies giving targeted radiation after a liver procedure called trans-arterial chemoembolization for hepatocellular carcinoma (HCC). It may help control the cancer in people who cannot have surgery or transplant.
Aachen, North Rhine-WestphaliaAges 18–80 - NCT04835480RecruitingPhase 2
Study drug for swelling from advanced liver scarring
This Phase 2 trial tests OsrHSA in people with advanced cirrhosis who have swollen belly fluid (ascites). It aims to see whether the treatment can improve outcomes in this difficult liver condition.
Changchun, JilinAges 18–80 - NCT04875325Enrolling by invitation

Nijmegen, GelderlandAges 18 years+ - NCT05054361Recruiting
Study gut immunity changes in children with type 1 diabetes
This study looks at how a type of immune cell (MAIT cells) and the gut (microbiota and gut lining) change around the time type 1 diabetes starts in children. It may help researchers understand why type 1 diabetes begins and how the gut and immune system are connected.
AntonyAges 1–15 - NCT05257746Recruiting
Testing bladder and rectal function after rectal surgery
This study follows people after rectal surgery to check how well the rectum and urinary (bladder) functions work over time. It may help doctors better understand recovery and what can improve quality of life after surgery.
Dresden, SaxonyAges 18 years+ - NCT04903470Recruiting
Study bowel movement patterns in constipation and healthy adults
This study compares bowel movement patterns in people with chronic constipation versus people without constipation. It may help researchers better understand what’s happening in constipation to guide future care and treatments.
San Diego, CaliforniaAges 21–75 - NCT05260385RecruitingPhase 1/Phase 2
Study drug KC1036 for advanced digestive cancers
This early-phase study tests whether KC1036 can treat advanced digestive system cancers that have come back or spread after standard treatment. It may help people by shrinking tumors or slowing growth, and it will also check safety and side effects.
