Study genes in people who respond unusually to treatment
This study looks at stored tumor samples to understand why some people respond much better or much worse than expected. The goal is to learn what the tumor’s genes might be telling doctors about response to treatment.
Toronto, OntarioAges 18 years+ - NCT03747588Recruiting
Laparoscopic versus open surgery for pancreas cancer
This study compares two ways of doing pancreaticoduodenectomy (a major surgery to remove parts of the pancreas and nearby tissue): minimally invasive (often smaller incisions) versus open surgery. It may help clarify which approach works best when the cancer looks potentially removable.
Beijing, Beijing MunicipalityAges 18–75 - NCT03748485Recruiting
Chemo after surgery for certain stage III colon cancer
This trial studies whether adding chemotherapy after surgery helps people with colon cancer that was diagnosed before surgery as stage III and later found to be without certain high-risk features. It may help lower the chance the cancer comes back, but you must meet specific surgery and health criteria.
Guangzhou, GuangdongAges 18–75 - NCT03755739RecruitingPhase 2/Phase 3
Checkpoint cancer drug given into or near tumors
This trial studies whether giving immunotherapy “checkpoint inhibitor” medicine directly into the tumor area (and/or the artery feeding it), along with a chemotherapy-style drug, can work better for advanced solid tumors. It aims to boost the immune system’s ability to attack cancer while still being safe for people with measurable tumors.
Guanzhou, GuangdongAges 18 years+ - NCT03770936RecruitingPhase 3
Drugs to reduce liver scarring in chronic hepatitis C
This Phase 3 study tests medicines to see whether they can reduce liver scarring (fibrosis) in people with long-term hepatitis C. If you qualify, you may receive the study treatment and be monitored over time to see how your liver is affected.
TantaAges 20 years+ - NCT03773887Recruiting
Study of liver inflammation and healing in alcohol-related liver disease
This study compares patterns of liver inflammation and the liver’s healing ability in people with alcohol-related liver disease, using blood tests and (in most cases) a liver tissue sample. It may help doctors better understand what is happening in the liver and how it may recover.
LilleAges 18–70 - NCT03775837Recruiting
Ginseng extract to improve abnormal liver blood tests
This trial studies whether a Panax ginseng extract can improve liver-related blood test results in adults. It may help people with mildly to moderately elevated liver enzymes, while carefully excluding people with other liver causes.
YangsanAges 19–75 - NCT03779009Recruiting
Study mapping sentinel lymph nodes to guide colon cancer surgery
This trial looks at a minimally invasive surgery approach for people with colon adenocarcinoma that has not spread to lymph nodes or other organs. The team will use special mapping tests on the sentinel lymph node to better understand the cancer spread and help guide treatment decisions.
GhentAges 18 years+ - NCT03785743Recruiting
Compare keyhole vs open surgery for pancreatic cancer
This trial compares two ways of doing surgery for pancreatic cancer: keyhole (small cuts) versus open surgery (one larger cut). It’s meant to see which approach works better for people who are well enough for either option.
Wuhan, HubeiAges 18–75 - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
BronAges 18 years+ - NCT03787771Recruiting
Fecal transplant registry for donors and recipients
This is a registry that collects information from adults who either receive fecal microbiota transplant (FMT) or plan to receive it, and from people who have donated—or plan to donate—stool for FMT. It helps researchers understand who participates in these gut-microbiome treatments in real life.
Hong KongAges 18 years+ - NCT03792919RecruitingPhase 4
Stopping long-term hepatitis B medicine vs continuing
This study compares outcomes for people with chronic hepatitis B who have long-term, stable viral suppression: stopping their antiviral medicine versus continuing it. It may help answer whether it’s safe to stop treatment in the right patients.
Hong Kong, Hong Kong SARAges Any age - NCT03791073Recruiting
Looking for New Markers in Pancreatic Cancer
This study looks for new markers in the blood or tissue of people with a pancreatic mass that might be cancer. It uses samples from a routine biopsy or surgery to help doctors learn more about the disease.
Montpellier, MontpellierAges 18 years+ - NCT03792854Recruiting
Quality-of-life study after standard treatment for anal cancer
This observational study follows people with anal cancer to understand how their quality of life changes after they receive standard chemoradiation therapy. It may help doctors better support patients with symptoms, recovery, and daily functioning over time.
Munich, BavariaAges 18 years+ - NCT03803553RecruitingPhase 3
Testing blood tumor DNA treatment after stage III colon surgery
This trial studies how to find tiny hidden cancer cells after stage III colon cancer surgery using a blood test. If the blood test shows tumor DNA, you may get additional treatment to lower the chance of cancer coming back.
Boston, MassachusettsAges 18 years+ - NCT03800693RecruitingPhase 2
Shorter vs longer oxaliplatin infusions for gut cancer
This Phase 2 study compares giving oxaliplatin by IV for 2 hours versus 6 hours, along with the standard FOLFOX6 chemotherapy. It aims to see if the shorter infusion works as well and is manageable for people with gastrointestinal cancers.
Atlanta, GeorgiaAges 18 years+ - NCT03803423Recruiting
Using social media to find kidney or liver donors
This study tests a way to spread information on how to register as a live organ donor using social media. You may be contacted to help identify potential live kidney or liver donors, if you fit the study’s basic requirements.
San Diego, CaliforniaAges 18 years+ - NCT03804931RecruitingPhase 2/Phase 3
Stool transplant for moderate to severe ulcerative colitis
This trial tests whether transplanting stool bacteria into the colon (fecal microbiota transplantation) can improve ulcerative colitis symptoms in people with active, moderate to severe disease. If you qualify, the study team will also check that it’s safe for you and that you can safely undergo a scope exam.
Guangzhou, GuangdongAges 18–65 - NCT03805919Recruiting
Study for men with high inherited risk of prostate cancer
This study is for men who have a known inherited gene change that raises their prostate cancer risk. It aims to help prevent or detect prostate cancer earlier, and you may be asked to undergo MRI and other study steps.
Bethesda, MarylandAges 30–75 - NCT03807687Recruiting
Registry for people with pancreatic diseases
This is a registry that collects information from people who have a pancreatic disease. It may help doctors better understand different pancreatic conditions and improve future care.
VeronaAges 18 years+ - NCT03809728Recruiting
Finding blood tests linked to outcomes in Crohn’s and colitis
This study looks for “biomarkers” (lab markers, like substances in blood or tissue) that may predict how Crohn’s disease or ulcerative colitis will go and how patients may respond. It may help doctors choose better monitoring or treatments in the future.
Vandœuvre-lès-NancyAges 18 years+ - NCT03811236Recruiting
Test cold exposure to activate body fat and reduce liver fat
This study tests whether controlled cold exposure can activate “brown fat” and affect liver fat buildup. It may help people with excess liver fat, measured on imaging, but it has several health and medication exclusions.
ViennaAges 18–50 - NCT03812718Recruiting
Breathing tube vs throat airway during gallbladder surgery
This trial compares two ways of managing your breathing while you are under anesthesia for elective laparoscopic gallbladder removal. It aims to see which option needs less anesthesia and is safer and easier to use for patients like you.
New Delhi, National Capital Territory of DelhiAges 18–65 - NCT03812874RecruitingPhase 1/Phase 2
Drug after chemo-embolization for liver cancer that can’t be removed
This Phase 1/2 study tests PTX-9908 (a study drug) to see if it’s safe and effective when given after TACE, a liver-directed treatment. It may help people with liver cancer that can’t be surgically removed and who have recovered enough from their recent TACE.
