Omaha, NebraskaAges 19 years+ - NCT03569826Recruiting
Study for primary biliary cholangitis and autoimmune hepatitis
This study is for people diagnosed with primary biliary cholangitis or autoimmune hepatitis. It aims to learn more about these autoimmune liver conditions and may help guide better care in the future.
Calgary, AlbertaAges 18 years+ - NCT03572465Recruiting
Ultrasound tests to diagnose fatty liver inflammation
This study checks whether special ultrasound measurements can help diagnose nonalcoholic steatohepatitis (NASH), a type of fatty liver disease. You may need a liver biopsy as part of routine care, and you may also be scanned with MRI to support the study tests.
Montreal, QuebecAges 18 years+ - NCT03581773RecruitingPhase 2
Folic acid to reduce mouth sores during kidney cancer treatment
This Phase 2 trial tests whether folic acid can lessen mucositis (painful mouth sores) caused by certain kidney cancer medicines. You would either take folic acid or an inactive pill, and the study looks for improvement in these side effects.
Aarhus, Central Region of DenmarkAges 18 years+ - NCT03579836RecruitingPhase 1/Phase 2
Test BEY1107 plus gemcitabine for pancreatic cancer
This early study tests whether BEY1107 given alone or with gemcitabine can be used safely and may help shrink pancreatic cancer tumors. It mainly looks at safety, side effects, and signs of effectiveness in people with pancreatic ductal cancer.
SeoulAges 20–80 - NCT03582189Recruiting
MRI guidance during treatment for pancreas or liver cancers
This trial studies using MRI scans to guide radiation therapy for locally advanced pancreas cancer or liver cancer. It may help make radiation planning more precise, either to control the cancer or to ease symptoms.
Toronto, OntarioAges 18 years+ - NCT03584204Recruiting
Imaging study for people with liver cirrhosis
This study looks at how liver cirrhosis shows up on non-invasive imaging like CT scans, and how those findings relate to outcomes. It may help researchers better understand what scan patterns could signal disease severity.
BonnAges 18–80 - NCT03587480Recruiting
Surgery methods after chemo-radiation for stage 3 rectal cancer
This trial compares two different surgery approaches after chemo-radiation for stage 3 rectal cancer. It aims to see which operation helps control the cancer more effectively while keeping surgery as safe as possible.
Guangzhou, GuangdongAges 18–75 - NCT03587831Recruiting
Weight-loss surgery plus lifestyle changes for fatty liver disease
This trial studies whether vertical sleeve gastrectomy (a type of weight-loss surgery) plus lifestyle coaching works better than another planned approach to improve non-alcoholic steatohepatitis (NASH), a serious form of fatty liver disease. It may help people reduce liver fat and inflammation, but you must be willing to follow study visits and possible random assignment.
San Francisco, CaliforniaAges 30–70 - NCT03587961RecruitingEarly Phase 1
Personalized testing to find the best CF medicine for you
This early study tests an individualized approach (“theratyping”) to match your cystic fibrosis (CF) to the CFTR medicine that may work best for your specific genetic change. It may help find a more tailored treatment plan and see how your body responds, while using medicines that are already approved for some people with CF.
Birmingham, AlabamaAges 6 years+ - NCT03589183Recruiting
Gut microbiome study for ulcerative colitis and Crohn disease
This study looks at how changes in gut bacteria (the microbiome) relate to inflammatory bowel disease, including ulcerative colitis and Crohn disease. It may help researchers understand what might improve symptoms or disease control.
SeoulAges Any age - NCT03594630RecruitingEarly Phase 1
Watchful waiting then chemotherapy before surgery for rectal cancer
This trial studies whether a period of active surveillance (watching closely) and chemotherapy before surgery can improve outcomes for people with stage II–III rectal cancer. You would also receive standard chemo-radiation if you qualify, then proceed to surgery.
