Laparoscopic total stomach surgery trial for stomach cancer
This trial studies whether a minimally invasive (laparoscopic) removal of the entire stomach, along with lymph node removal, can be done safely and effectively for certain stomach cancers. It may be an option if your cancer is in the stomach, has limited spread to nearby lymph nodes, and can be fully removed.
SeoulAges 20–80 - NCT03401294RecruitingPhase 2
Turn unresectable liver cancer into operable colorectal cancer
This Phase 2 study tests a treatment strategy to shrink or control colorectal cancer that has spread only to the liver, with the goal of making it removable by surgery. If you qualify, it may offer a chance to move from “not operable” to “operable,” but it’s still experimental.
Regina, SaskatchewanAges 18–70 - NCT03409263Recruiting
Registry for people with TIPS for high portal pressure
This study is a registry, meaning it collects health information to better understand people who have a TIPS procedure for high pressure in the liver’s blood vessels. It may help doctors improve how TIPS is used and monitored over time.
Vienna, State of ViennaAges 18–99 - NCT03418350Recruiting
Study how acid reflux may affect lung scarring
This trial studies whether reflux (acid moving up toward the throat) plays a role in idiopathic pulmonary fibrosis (IPF), a condition where lung tissue becomes scarred. It may help doctors understand triggers that could worsen symptoms and guide more targeted care.
Denver, ColoradoAges 40–95 - NCT03434392Recruiting
Testing pain-sensing to predict treatment response in chronic pancreatitis
This study uses a special pain-testing method to better predict how people with chronic pancreatitis-related pain (or similar conditions) will respond to treatment. It may help doctors choose therapies that work better for each person’s type of pain.
Baltimore, MarylandAges 18 years+ - NCT03445585Recruiting
Biobank study for primary sclerosing and primary biliary cholangitis
This study collects and stores samples from people with PSC (primary sclerosing cholangitis), PBC (primary biliary cholangitis), and some related liver conditions. Researchers use these samples to better understand these diseases and support future research.
Rochester, MinnesotaAges 18–85 - NCT03449264Recruiting
Database study for people with certain new cancers
This study builds a clinical and biological database for people newly diagnosed with certain cancers. It may help doctors better understand cancer patterns and improve future care, and it involves agreeing to extra blood samples.

Study of bowel inflammation in adults with AML on intensive treatment
This study looks at how often a serious bowel problem (neutropenic enterocolitis) happens in adults with acute myeloid leukemia (AML) during intensive chemotherapy that lowers infection-fighting cells. The results may help doctors monitor and prevent complications during treatment.
AmiensAges 18 years+ - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Birmingham, AlabamaAges Any age - NCT03458195Recruiting
Crohn’s surgery follow-up for ileocecal resection patients
This study follows adults with Crohn’s disease who need surgery to remove the ileocecal area. It aims to better understand post-operative outcomes and what to expect after the operation.
LiègeAges 18–100 - NCT03463668Recruiting
Testing a specific duodenal stent for duodenal narrowing
This trial is looking back at people with symptoms from narrowing of the duodenum (the first part of the small intestine) who had a specific type of stent placed between 2010 and 2017. It may help doctors understand how well these “uncovered” duodenal stents work over time, and who benefits.
Marseille, Bouches Du RhoneAges 18 years+ - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT03465982Recruiting
Timing surgery after chemotherapy and radiation for rectal cancer
This trial studies the best time to do surgery after you finish chemotherapy and radiation for rectal cancer. It may help improve how well minimally invasive surgery works and how safely it can be done.
Alessandria, ALAges 18 years+ - NCT03469609Recruiting
Feeding plan for babies with a mucous fistula after bowel surgery
This trial studies whether a specific feeding approach helps babies start full tube feeding sooner after surgical closure of an enterostomy (a stoma). It may help reduce the time until your baby is fully fed through the gut.
GrazAges Up to 1 year - NCT03471403Recruiting
Cold snare removal for duodenal growths in FAP
This trial studies removing small growths in the duodenum (a part of the small intestine) in people with familial adenomatous polyposis (FAP) using a “cold snare” technique. It may help reduce the need for more intensive treatment and make follow-up care safer, but you must meet specific safety and readiness requirements.
Westmead, New South WalesAges 18–99 - NCT03472157Recruiting
Bariatric surgery for severe NASH with advanced liver scarring
This study tests whether bariatric surgery (either sleeve gastrectomy or Roux-en-Y gastric bypass) improves severe nonalcoholic steatohepatitis (NASH) with advanced liver scarring in people who are obese. You may also need liver biopsies to confirm your liver disease before and after treatment.
LilleAges 18–65 - NCT03484299RecruitingPhase 1
Study chemo plus irreversible electroporation for stage III pancreatic cancer
This early study tests a combination of chemotherapy and a procedure called irreversible electroporation (IRE) for people with stage III pancreatic cancer. It may help shrink or control tumors, and also studies safety in this group.
Louisville, KentuckyAges 18 years+ - NCT03480971RecruitingPhase 2
Tempol to reduce mouth and other side effects from radiation and cisplatin
This Phase 2 trial tests tempol to lessen harmful side effects caused by head-and-neck radiation and the chemotherapy drug cisplatin. If you qualify, you may receive tempol during treatment to help protect normal tissues and reduce toxicity.
La Jolla, CaliforniaAges 18 years+ - NCT03492151Recruiting
Scans pancreatic cysts during a biopsy procedure
This trial tests a special camera (confocal laser endomicroscopy) used during an ultrasound-guided needle biopsy to help tell what type of pancreatic cyst is present. It may help doctors decide faster whether surgery is needed.
Scottsdale, ArizonaAges 18 years+ - NCT03492671RecruitingPhase 2
Two chemotherapy drugs plus radiation before pancreatic surgery
This trial tests whether giving two already-approved chemotherapy drugs and radiation before surgery works better for localized pancreatic cancer. It’s meant for people whose cancer looks removable by surgery and who haven’t had prior pancreatic cancer treatment.
Loma Linda, CaliforniaAges 18 years+ - NCT03494946Recruiting
Liver transplant vs chemotherapy for colon cancer liver spread
This trial compares liver transplantation to standard chemotherapy for people with colon or rectal cancer that has spread to the liver but cannot be removed surgically. It looks at whether transplant can help patients live longer or better than chemotherapy in the right patients.
OsloAges 18 years+ - NCT03498326RecruitingPhase 2
Gemcitabine plus celecoxib after pancreatic surgery
This trial tests whether adding celecoxib to gemcitabine chemotherapy after complete (R0) pancreatic tumor removal can lower the chance the cancer comes back. It may help people who have had successful surgery but still need anti-cancer treatment.
Hangzhou, ZhejiangAges 18–90 - NCT03516708RecruitingPhase 1/Phase 2
Epacadostat with pre-op radiation for locally advanced rectal cancer
This trial studies whether adding epacadostat (a cancer drug) to standard pre-operative chemoradiation can improve outcomes for people with locally advanced rectal cancer. It’s designed to see if the added treatment is safe and potentially more effective before surgery.
Orange, CaliforniaAges 18 years+ - NCT03535142Recruiting
Fatty liver in people considering bariatric surgery
This study looks at how fatty liver disease may predict future liver health in people with severe weight gain. It compares people who are planning bariatric (weight-loss) surgery with similar people who are not, to better understand who may be at higher risk.
