Hong Kong, NTAges 18–99 - NCT03250078Recruiting
Pancreatic cancer screening for people at high genetic risk
This study offers pancreatic cancer screening for people with strong family history or certain inherited gene changes. It may help find pancreatic cancer earlier, when treatment may be more effective.
Norwalk, ConnecticutAges 50–90 - NCT03250091Recruiting
Stomach precancer check-up study after scope
This study follows people who have had an upper endoscopy (a camera test through the mouth to look at the stomach) to monitor precancerous stomach changes. It may help doctors learn the best way to watch these spots over time and catch problems early.
RigaAges 18 years+ - NCT03256240Recruiting
Two surgical options for Crohn’s bowel resection
This trial compares two ways of reconnecting the bowel after surgery in people with Crohn’s disease that affects the small intestine and/or colon. It aims to see which reconnection method works better after the initial surgery, even if you’re on Crohn’s medicines before the operation.
Boston, MassachusettsAges 18–90 - NCT03259867RecruitingPhase 2
TACE plus immune therapy for liver or stomach cancer
This trial tests a combination treatment using a targeted liver procedure plus an immune “checkpoint” medicine to slow cancer growth. It may help people with advanced liver cancer (HCC) or metastatic stomach cancer when standard treatments have not worked.
Orange, CaliforniaAges 18–80 - NCT03261934Recruiting
Modeling risk and progression in chronic stomach lining disease
This study looks at people with chronic atrophic gastritis to estimate who may be at higher risk of stomach cancer over time. It collects symptom and medical data, plus blood and tissue samples, to build prediction models that may improve future care.
Beijing, Beijing MunicipalityAges 18–75 - NCT03267069Recruiting
Study of alcohol use in alcoholic liver disease
This study looks at alcohol use behaviors in people who have alcoholic liver disease. It may help researchers better understand patterns of alcohol use and how to support safer health decisions.
New York, New YorkAges 18–80 - NCT03273049Recruiting
Study of disease processes in children getting liver transplants
This study maps how biliary atresia (a childhood blockage/problem with bile flow from the liver) progresses and changes in the body around the time of a liver transplant. It may help doctors better understand the disease and improve future care.
Pittsburgh, PennsylvaniaAges Any age - NCT03280511RecruitingPhase 2
After surgery chemo sprayed into the abdomen for high-risk colon cancer
This Phase 2 study tests whether spraying chemotherapy into the abdomen (through a small procedure) after colon cancer surgery can lower the chance the cancer comes back. It is meant for people with high-risk tumor features but who have had surgery and have no proven relapse yet.
OdenseAges 18 years+ - NCT03303495RecruitingPhase 3
Second-line chemo with or without bevacizumab for colon cancer
This Phase 3 study compares two treatment plans for people with metastatic colorectal cancer that got worse or caused side effects after first chemotherapy. It looks at whether adding bevacizumab (a medicine that targets blood vessels feeding tumors) improves outcomes versus using a different chemotherapy approach.
Guangzhou, GuangdongAges 18 years+ - NCT03303547Recruiting
Matching scans and biopsy results in colon and rectal cancer
This study looks at how well cancer found on scans matches the actual cancer seen under the microscope after surgery. It may help improve how doctors plan treatment for colon, sigmoid, or rectal adenocarcinoma.
London, SurreyAges 16 years+ - NCT03303833Recruiting
Lynch syndrome study following people over time
This study follows adults with Lynch syndrome (an inherited gene change) using regular questionnaires and tracking health over time. It may help researchers understand how the condition progresses and improve care for people with these gene mutations.
WageningenAges 18–80 - NCT03308916Recruiting
Screening for liver scarring risk using noninvasive tests
This study checks people who are at higher risk for liver scarring by using noninvasive tests. If those tests suggest significant scarring, the study may consider further testing, but not everyone will need a biopsy.
OdenseAges 30–75 - NCT03311776Recruiting
Study blood and tissue markers in pancreatic cancer
This study looks at “biomarkers” (test signals in tissue or blood) in people with pancreatic cancer. It may help researchers understand the disease better and find ways to predict or track it.
HerlevAges 19 years+ - NCT03322995RecruitingPhase 2
Neoadjuvant chemo study for resectable pancreatic cancer
This Phase 2 trial tests a chemotherapy plan given before surgery (called “neoadjuvant” treatment) for people with pancreatic adenocarcinoma that looks resectable or borderline resectable on scans. The goal is to see how well this adaptive chemotherapy approach works and whether it can improve outcomes before an operation.
Milwaukee, WisconsinAges 18 years+ - NCT03326154Recruiting
Improving quality of life after gallbladder removal
This study focuses on how people feel after having their gallbladder removed for painful, symptomatic gallstones. You may be asked to fill out questionnaires to compare quality of life after surgery and help researchers understand what recovery feels like for patients.
EspooAges 18 years+ - NCT03334006RecruitingPhase 2
Tested special immune-targeting treatment after abdominal infection surgery
This Phase 2 study tests whether Pentaglobin®, a blood-product made from immune proteins, helps critically ill people with severe abdominal infection (peritonitis) after the infection source is surgically cleaned up. It targets patients with signs of strong inflammation and severe illness.
ViennaAges 18 years+ - NCT03339128RecruitingPhase 2
Eluxadoline for diarrhea-predominant IBS in children
This trial tests whether eluxadoline can reduce symptoms of IBS with diarrhea (IBS-D) in children ages 6 to 17. It also asks families to track symptoms with a daily diary to measure whether treatment helps over the study period.
Hot Springs, ArkansasAges 6–17 - NCT03349762Recruiting
Huaier granules to help prevent colorectal cancer coming back
This study tests whether Huaier granules after surgery can lower the chance that colorectal cancer returns or spreads. It is for people who have recently had “radical” (complete) surgery for certain stages of colorectal cancer and are within about 2 months of that surgery.
Shijiazhuang, HebeiAges 18–75 - NCT03368651RecruitingPhase 3
Testing a pre-surgery infusion to improve liver cancer outcomes
This trial tests whether giving medicine directly into the liver blood vessels before surgery can improve survival for people with liver cancer that has a blockage (tumor in the portal vein). It compares this approach plus surgery versus surgery alone in a randomized study.
