Indianapolis, IndianaAges 18 years+ - NCT04406831Recruiting
Testing microRNA for pancreatic cancer diagnosis and treatment response
This study looks at tiny molecules in your body (microRNA) to help doctors better diagnose pancreatic cancer, predict how it may progress, and understand how it responds to treatment. It may help guide more personalized care in the future.
Norwalk, ConnecticutAges 18 years+ - NCT04411823Recruiting
Predicting reflux after stomach sleeve surgery
This trial looks at how to predict who will develop acid reflux after a “stomach sleeve” operation. It may help doctors choose the safest plan before surgery and better prevent reflux afterward.
Orlando, FloridaAges 18 years+ - NCT04415853RecruitingPhase 3
Larotinib for advanced esophageal cancer with high EGFR
This phase 3 trial tests larotinib, a targeted cancer medicine, for people with advanced or recurrent esophageal cancer that has high EGFR. It aims to see if it works better than standard treatment approaches after the cancer has progressed twice.
Beijing, Beijing MunicipalityAges 18–80 - NCT04416581RecruitingPhase 4
Compare two stomach-protecting medicines to prevent bleeding
This trial compares a potassium-competitive acid blocker to a proton pump inhibitor to help prevent stomach or intestinal bleeding in people at high risk who take blood-thinning medicines. It may help reduce dangerous GI bleeding while you stay on heart/stroke medicines.
AnyangAges 19 years+ - NCT04421924Recruiting
Blood clot control during TIPS in people with cirrhosis
This study looks at how to manage blood clotting around the time of a TIPS procedure in adults with cirrhosis, to see if a safer clotting strategy helps. It may be useful if you are having TIPS for a specific complication of liver disease.
GrazAges 18 years+ - NCT04421820RecruitingPhase 1/Phase 2
BOLD-100 with chemo for advanced gut cancer
This Phase 1/2 study tests whether BOLD-100, given with the standard chemo combination FOLFOX, can help people with advanced gastrointestinal cancers. It’s especially focused on specific tumor features (including BRAF status) and checks safety, dosing, and early signs of effectiveness.
Santa Monica, CaliforniaAges 18 years+ - NCT04422405Recruiting
One-anastomosis stomach bypass study for reflux and stomach changes
This study looks at how a one-anastomosis gastric bypass changes how your stomach and esophagus work, especially relating to acid reflux. You may be offered the planned surgery if you fit the weight and heartburn/reflux-related conditions, and the team will measure changes before and after.
Schlieren, Canton of ZurichAges 18–65 - NCT04429100Recruiting
Breath-hold MRI test to measure liver scar levels
This study tests an MRI technique that briefly holds your breath to measure how scarred your liver tissue is. It may help doctors better spot and track liver fibrosis (scarring).
Hong Kong, ShatinAges Any age - NCT04429542RecruitingPhase 1
Test of an EGFR-targeting drug for advanced solid cancers
This Phase 1 study tests the safety of BCA101 (an EGFR-targeting treatment) alone or combined with pembrolizumab. It may help people with certain EGFR-driven advanced cancers, depending on the tumor type, prior treatments, and required biopsy testing.
La Jolla, CaliforniaAges 18 years+ - NCT04430452RecruitingPhase 2
Durvalumab with or without tremelimumab after liver radiation
This study tests whether the immunotherapy drugs durvalumab (with or without tremelimumab) can help control hepatocellular carcinoma (liver cancer) after you receive palliative, targeted radiation. It especially focuses on people whose cancer continued to grow after, or without, certain prior immune therapies.
San Francisco, CaliforniaAges 18 years+ - NCT04434781Recruiting
G-POEM procedure for treating stomach slow emptying
This trial looks at a stomach procedure called G-POEM to help relieve symptoms of gastroparesis, which means the stomach empties too slowly. If you’re an adult with confirmed gastroparesis and have been referred for endoscopic treatment, you may be able to take part.
Indianapolis, IndianaAges 18 years+ - NCT04442334Recruiting
European registry for people with fatty liver
This registry collects health and lifestyle information from adults with suspected or confirmed fatty liver (NAFLD) to help researchers better understand the condition. You may be asked about diet, exercise, alcohol intake, and some liver-related tests.
AntwerpAges 18–100 - NCT04443478Recruiting
Keyhole versus open lymph node surgery for junction cancer
This trial compares two ways of removing lymph nodes during surgery: keyhole (laparoscopic) versus open surgery. It is for people with esophagus-stomach junction adenocarcinoma, aiming to see which approach works better and is safer.
Beijing, Beijing MunicipalityAges 18–80 - NCT04446832Recruiting
Vaccine study for people waiting for liver transplant
This study tests a vaccine strategy for people who are being evaluated and waiting for a liver transplant. The goal is to see how well the immune system responds and how the results are interpreted before transplant.
LyonAges 18 years+ - NCT04447911RecruitingPhase 4
Empagliflozin for chronic low blood sodium in certain fluid states
This trial studies whether empagliflozin, a blood-sugar–related medicine, can safely improve chronic low blood sodium when you are not too “dry” or have an imbalanced fluid state. It may help stabilize sodium levels and related health symptoms, but you must meet specific blood and organ-function criteria.
WürzburgAges 18 years+ - NCT04448028RecruitingPhase 4
Stopping acid pills in liver cirrhosis: test placebo effect
This study tests whether stopping proton-pump inhibitor (PPI) acid-reducing medication is safe and works as expected for people with liver cirrhosis. Participants switch to either the study medication or a placebo (inactive pill) under close monitoring.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT04447352RecruitingPhase 3
HIPEC plus FLOT versus FLOT alone for gastric or GE junction cancer
This trial compares two treatment approaches after your stomach/GE junction cancer has been treated with chemotherapy before surgery: adding a special heated bath into the abdomen (HIPEC) plus continuing the usual surgery plan. It aims to see if adding HIPEC lowers cancer coming back and improves outcomes.
AachenAges 18–75 - NCT04450758Recruiting
Stent or stoma right away versus surgery later for bowel blockage
This trial studies treatment choices for adults with a large-bowel blockage caused by colon cancer. It compares doing an emergency procedure now (like a stent or stoma) versus bridging to a later colon surgery, to see which approach is safer and works better.
GothenburgAges 18–100 - NCT04455282Recruiting
Blood test-guided surgery for gastroesophageal cancer
This trial studies blood-based biomarkers to help doctors choose the best individualized surgical treatment for gastroesophageal junction adenocarcinoma. If you qualify, you’ll get standard care plus additional testing to see whether the blood results can guide surgery more precisely.
Cologne, North Rhine-WestphaliaAges 18 years+ - NCT04455932Recruiting
Test shorter MRI versus ultrasound for liver cancer screening
This study compares a shorter, non-contrast MRI and ultrasound to monitor for liver cancer in people with cirrhosis whose ultrasound images aren’t clear enough. It aims to see which method works better and may help you get safer, more reliable follow-up.
Camperdown, New South WalesAges 20–85 - NCT04460352RecruitingPhase 3
Esophageal cancer treatment with chemoradiation plus planned surgery
This trial tests the best way to treat locally advanced squamous cell esophageal cancer: either chemoradiation followed by planned surgery, or monitoring with surgery only if needed. It may help you choose a strategy that controls the cancer while aiming to reduce unnecessary procedures.
