High-dose vitamin D for kids with IBD on biologic therapy
This trial studies whether giving a higher dose of vitamin D3 helps children and teens with inflammatory bowel disease (Crohn’s or ulcerative colitis) who have low vitamin D levels. Participants are already on biologic medicines and will be treated while monitoring blood (and safety) related to vitamin D.
Boston, MassachusettsAges 5–25 - NCT04340817Recruiting

Ultrasound and light imaging during rectal cancer surgery
This study tests a newer kind of imaging (ultrasound plus light-based measurements) to help doctors tell rectal cancer apart from other tissue during surgery. You may be able to take part if you’re having surgery for rectal cancer and the tumor is close enough to the anus.
St Louis, MissouriAges 19 years+ - NCT04340986Recruiting
Group study for bile duct or liver cancer patients
This study follows people with bile duct cancer or certain liver cancers to better understand their disease. You might be included if you meet the diagnosis and basic participation requirements.

Test camrelizumab plus apatinib for advanced stomach cancer
This trial studies whether combining camrelizumab (an immunotherapy) and apatinib (a targeted pill) can control advanced, unresectable stomach or gastroesophageal junction cancer that has grown after first treatment. It also looks at how safe the combination is.
BeijingAges 18 years+ - NCT04348838Recruiting
Study of people newly diagnosed with liver cancer in France
This study follows people with hepatocellular carcinoma (HCC), a type of liver cancer, to learn how it changes over time. It may help improve understanding of which patients benefit from different care approaches.
AmiensAges 18 years+ - NCT04354064Recruiting
Blood DNA test to see early treatment response in solid tumors
This study looks at circulating tumor DNA, which is tiny bits of DNA found in blood, to help assess how solid tumors are responding early. It uses blood samples from healthy adults who are willing to donate.
St Louis, MissouriAges 18 years+ - NCT04358146Recruiting
Test a new formula to reduce infant spit-up
This study tests whether a new anti-regurgitation infant formula can reduce how often your baby spits up, and whether babies tolerate it well. It may help families who are feeding with formula and seeing frequent regurgitation (spit-up).
NamurAges 2 weeks–4 months - NCT04364373Recruiting
Test of different lymph node surgery for left colon cancer
This study compares two types of lymph node removal during surgery for left-sided colon cancer. It aims to see which surgical approach may work better while ensuring you can still safely complete chemotherapy.
MoscowAges 18–75 - NCT04365751Recruiting
Microwave ablation versus surgery for liver cancer
This trial compares two ways to treat hepatocellular carcinoma (a type of liver cancer): microwave ablation and laparoscopic hepatectomy (keyhole liver surgery). It may help find which option works better for tumor control and recovery in people with limited, non-spread cancer.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04365855Recruiting
Study of fatty liver risk in local adults
This study looks at how common fatty liver disease is and what factors may be linked to it in adults in Olmsted County. You may be asked about health history, alcohol use, and possibly to undergo MRI scans.
Rochester, MinnesotaAges 18 years+ - NCT04366999Recruiting
Bariatric surgery for fatty liver disease in people with obesity
This trial looks at whether weight-loss (bariatric) surgery helps people with fatty liver disease, including “NASH,” and related liver scarring. If you have obesity and a confirmed liver fat diagnosis (and for NASH, biopsy-proven NASH with some fibrosis), the study may follow your outcomes after surgery.
Beijing, Beijing MunicipalityAges 16–65 - NCT04368702Recruiting
MRI-guided radiation for people needing radiation for cancer
This study tests whether radiation given with help from MRI (a type of scan) can better treat cancers that need radiation. You may be eligible if your cancer is confirmed and you can safely have MRI scans.
Boston, MassachusettsAges 18 years+ - NCT04368663Recruiting
TJ-134 for bowel cysts causing symptoms
This trial looks at whether TJ-134, a traditional herbal medicine, helps people who have symptomatic pneumatosis cystoides intestinalis (bowel cysts). It may help reduce symptoms if the condition matches the typical colonoscopy findings.
Komagane, NaganoAges 18–100 - NCT04370574Recruiting
Testing blood or tissue markers for suspected pancreatic cancer
This trial looks for “soluble biomarkers” (markers that can be found in body fluids like blood) for people who have a pancreatic mass and may have pancreatic ductal adenocarcinoma. The goal is to improve how pancreatic cancer is identified, especially using information taken from an endoscopic ultrasound biopsy.
Montpellier, MontpellierAges 18 years+ - NCT04372108Recruiting
Long-term safety study for ustekinumab vs other biologics
This study follows adults with Crohn’s disease or ulcerative colitis to compare the long-term safety of ustekinumab against other biologic medicines. It may help show how safe these treatments are over time, using medical records.
Portsmouth, VirginiaAges 18 years+ - NCT04371042Recruiting
Study of liver disease and genes in people with fatty liver
This study collects information about metabolic and unexplained (cryptogenic) liver disease and looks at “omics” tests, which are lab tests that measure patterns in blood or tissue to learn what drives the disease. It may help researchers better understand fatty liver and related serious complications, like liver scarring and liver cancer.
Roma, Rome/lazio/italyAges 18 years+ - NCT04373564RecruitingPhase 4
Tracking brain and movement changes after repeated MRI contrast
This study looks at whether getting the MRI contrast dye multiple times over 5 years affects body movement and thinking skills. It compares people who had the dye repeatedly with people who have little or no exposure, using brain MRI scans and regular mental and movement testing.
Scottsdale, ArizonaAges 18–64 - NCT04374175Recruiting
Blood sample bank for pancreatic cancer patients and controls
This study collects and stores blood samples (“serum bank”) from people with pancreatic cancer and from comparison participants. The goal is to help researchers study the disease and improve future diagnosis or treatment planning.
Saint-EtienneAges 18 years+ - NCT04380545RecruitingPhase 1/Phase 2
Nivolumab plus chemo and immune drug for unresectable liver cancer
This Phase 1/2 trial tests whether nivolumab combined with fluorouracil and interferon alpha can treat fibrolamellar liver cancer that cannot be safely removed with surgery. It aims to shrink or control the cancer and to see how safe the combination is.
Houston, TexasAges 12 years+ - NCT04389086RecruitingPhase 3
Chemotherapy before surgery for recurring rectal cancer
This trial tests an “induction chemotherapy” treatment before surgery for people whose rectal cancer has come back in the local area. The goal is to shrink/control the cancer early and improve outcomes after treatment.
GhentAges 18 years+ - NCT04393519Recruiting
Program to monitor you after TIPS with noninvasive checks
This trial looks at a follow-up and monitoring program after TIPS (a procedure to improve blood flow in the liver). It is meant to make sure the TIPS is working and to guide follow-up without relying on invasive testing when possible.

High-dose omeprazole by mouth for serious ulcer bleeding
This trial tests whether taking a high dose of omeprazole by mouth can help control bleeding from a peptic ulcer that looks high-risk on endoscopy. It may be aimed at lowering the chance of bleeding again after your procedure.
