Colorectal cancer registry for people having bowel surgery
This study collects information and (likely) tumor-related lab results from adults with colorectal cancer who are having colorectal surgery. It helps researchers better understand the disease and could improve future treatment planning.
CABA, Buenos AiresAges 21–96 - NCT02869581Recruiting
Pancreatic tumor patient registry
This study builds a database of people diagnosed with pancreatic tumors. It may help researchers better understand these cancers by collecting medical information over time.
Marseille, Bouches du RhoneAges 18 years+ - NCT02869503Recruiting
Colorectal cancer registry study
This study builds a database of people with colorectal cancer. It may help doctors learn from real-world information to improve future care.
Marseille, Bouches du RhoneAges 18–95 - NCT02869802Recruiting
Study types of pancreatic cancer using tumor gene testing
This trial studies metastatic pancreatic cancer by taking a small tissue sample and analyzing its genes. It may help doctors better understand which cancer subtypes patients have, which can guide future treatment choices.
Calgary, AlbertaAges 18 years+ - NCT02885753RecruitingPhase 3
Liver-only metastatic colon cancer trial using targeted chemo
This Phase 3 trial tests different ways to deliver chemotherapy for colon cancer that has spread only to the liver (with limited possible tiny lung spots). It looks at whether the treatment plan improves outcomes compared with another chemotherapy approach, using oxaliplatin and LV5FU2 (with or without irinotecan) plus an added targeted medicine.
BrusselsAges 18 years+ - NCT03219359RecruitingPhase 2
Stem cell transplant using your own cells for Crohn’s flare
This Phase 2 study tests whether a transplant using your own stem cells can calm active Crohn’s disease that hasn’t improved with standard medicines. It may help some people with ongoing inflammation and symptoms after multiple Crohn’s treatments.
New York, New YorkAges 18 years+ - NCT02919644RecruitingPhase 2
Cancer vaccine made from your own cells after bowel cancer surgery
This trial tests whether a personalized vaccine—made from your own immune cells mixed with your own tumor material—can help prevent colorectal cancer from coming back after curative surgery. It may help your immune system recognize and fight any remaining cancer cells.
Meldola, FCAges 19 years+ - NCT02920554Recruiting
Surgery comparison for T2–T3 gallbladder cancer
This study looks at whether a specific type of liver surgery (removing tissue in a wedge shape versus a different liver resection) improves outcomes for some patients with T2 or T3 gallbladder cancer. It may help decide the best surgical approach after the gallbladder has already been removed.
SuwonAges 19–80 - NCT03183115Recruiting
Prevent return of esophagus pre-cancer after endoscopy
This trial looks at a prevention treatment to stop esophagus abnormal growth (pre-cancer or very early cancer) from coming back after successful endoscopic submucosal dissection. It focuses on people whose esophagus lining shows a “speckled” pattern on a special iodine test, which may mean higher risk of recurrence.
Kaohsiung CityAges 20–90 - NCT03161522RecruitingPhase 2
Chemo alone versus with radiation or surgery for limited spread
This study tests whether adding radiation or surgery to chemotherapy can improve outcomes for people whose esophageal or stomach cancer has spread to only a few places. If your cancer is “oligometastatic” (up to 3 spots), the trial helps doctors see which approach gives the best control.
Houston, TexasAges 18–79 - NCT03097185Recruiting
Checking how well transplanted islet cells work in chronic pancreatitis
This study looks at how well a treatment works after islet cell transplantation done for people with long-term (chronic) pancreatitis. It may help doctors better understand graft (transplant) function and how to choose the best approach and follow-up.
Dallas, TexasAges 18 years+ - NCT03253536Recruiting
Quality of life study after precise liver radiation
This study follows people with liver cancer (hepatocellular carcinoma) to see how their quality of life changes after a focused form of radiation called stereotactic ablative radiation therapy. It does not appear to test a new drug—rather, it measures patient-reported well-being after treatment.
Munich, BavariaAges 18 years+ - NCT02988921Recruiting
MRI and CT planning for esophagus or stomach-junction cancer treatment
This study checks whether MRI and CT scans can better measure how esophageal or stomach-junction tumors respond during chemoradiotherapy and help doctors map the exact treatment area. It may help improve targeting while you receive standard treatment.
BeijingAges 18 years+ - NCT03334292Recruiting
Study of the natural course of Wilson disease
This study follows people who already have Wilson disease to understand how the condition changes over time. It may help researchers better predict future symptoms and improve care.
New Haven, ConnecticutAges Any age - NCT03193151Recruiting
Microarray testing to guide care after liver transplant
This study looks at how special lab tests from tiny tissue samples (microarrays) could help guide diagnosis and treatment in people who receive a liver transplant. It may help doctors better understand what’s going on and choose care more accurately.
San Francisco, CaliforniaAges 18 years+ - NCT03146884Recruiting
Study of autoimmune hepatitis in people living in Switzerland
This study looks at people with autoimmune hepatitis (an immune system condition that attacks the liver). It aims to learn more about the disease by following patients who live in Switzerland.
Lugano, Canton TicinoAges Any age - NCT03161808Recruiting
CF rare mutation blood and tissue sample collection study
This study collects cells from people with cystic fibrosis (CF) caused by rare CFTR gene changes. The goal is to build a cell bank for future research, which may help scientists develop better tests and treatments for rare CF types.
Birmingham, AlabamaAges 17 years+ - NCT03093116RecruitingPhase 1/Phase 2
Repotrectinib for ALK, ROS1, or NTRK tumor gene changes
This trial studies repotrectinib, a targeted medicine, in people with advanced solid tumors that have specific gene rearrangements (ALK, ROS1, or NTRK). It may help shrink tumors or control cancer growth based on the patient’s tumor genetic result.
Duarte, CaliforniaAges 12 years+ - NCT03260842Recruiting
Biobank study for people at high risk of pancreatic cancer
This study collects and stores samples (bio-specimens) from adults who have pancreas cysts and are at higher risk for pancreatic cancer. The goal is to help researchers improve early detection so future patients may be diagnosed sooner.
Stanford, CaliforniaAges 18 years+ - NCT03146910Recruiting
Study of primary biliary cholangitis in Switzerland
This study follows adults with primary biliary cholangitis (a long-term liver and bile duct condition). It may help doctors better understand the disease in different people, including those identified by specific blood antibody tests.
Lugano, Canton TicinoAges 18 years+ - NCT03187925Recruiting
Treatment studies for Zenker’s or CP bar throat pouches
This trial studies people with Zenker’s diverticulum (or a related condition called CP bar) in the throat and upper food pipe. It looks at outcomes when the “shared wall” is divided using an open or endoscopic approach, or when surgery isn’t possible but follow-up can happen.
Cincinnati, OhioAges 18–100 - NCT03224949Recruiting
Study comparing fatty liver types and healthy livers
This study compares liver samples and blood tests from people with alcohol-related fatty liver disease, alcohol-related hepatitis, and cirrhosis (including some with liver cancer) against healthy controls. It aims to better tell these liver conditions apart and understand what is different between them.
Cleveland, OhioAges 18–75 - NCT03222635Recruiting
Follow-up for certain early esophageal cancer found by endoscopy
This study follows people whose early esophageal adenocarcinoma was found during an endoscopy (ER) sample. The goal is to better understand what follow-up tests are needed based on higher-risk features and to watch for spread or incomplete removal.
SydneyAges 18 years+ - NCT03209791Recruiting
Study alcohol-related effects on muscle recycling in the liver
This study looks at how alcoholic liver disease may change a natural body clean-up process in muscle. It compares people with alcoholic liver disease to people without it to better understand the biology and identify possible targets for treatment.
Cleveland, OhioAges 18–65
