New medicines with chemotherapy after short radiation for rectal cancer
This trial tests two new immune-related medicines (an anti–PD-1 drug and an adenosine blocker) added to standard chemotherapy after a short course of radiation for rectal cancer. It aims to improve cancer control while checking safety.
New York, New YorkAges 18–90 - NCT05024214RecruitingPhase 1/Phase 2
Test of envafolimab plus lenvatinib for advanced solid tumors
This trial studies whether combining envafolimab (an anti-immune cancer medicine) with lenvatinib (a targeted pill) can shrink or control advanced cancers that have stopped responding to standard care. It may help people whose tumors are not curable with usual treatments, by testing a new combo and finding safe doses.
Bengbu, AnhuiAges 18 years+ - NCT05027737Recruiting
Earlier ileostomy closure after rectal cancer surgery
This study looks at whether closing a temporary ileostomy sooner is safe after rectal cancer surgery, when imaging shows no leak. It may help people avoid living with the stoma for longer, but only if specific safety checks are passed.
Vancouver, British ColumbiaAges 18–90 - NCT05028829RecruitingPhase 2
Atorvastatin to lower liver cancer risk in people with liver scarring
This trial tests whether atorvastatin (a cholesterol medicine) can lower the chance of liver cancer (HCC) in people with advanced liver scarring or cirrhosis. Participants are compared to placebo (inactive pill) while researchers track safety and cancer risk.
Boston, MassachusettsAges 18 years+ - NCT05030571Recruiting
Plasma adsorption for adults with liver failure in the ICU
This trial studies a treatment called the Double Plasma Molecular Adsorption System (DPMAS) for people with acute-on-chronic liver failure while they are in the ICU. It aims to see whether filtering certain substances from blood can improve outcomes and safety for critically ill patients.
BangkokAges 18 years+ - NCT05033392RecruitingPhase 2
PD-1 therapy plus chemotherapy before stomach cancer surgery
This Phase 2 trial tests whether adding a PD-1 antibody (JS001/toripalimab) to chemotherapy before surgery can improve outcomes for people with locally advanced stomach or gastroesophageal junction adenocarcinoma. It aims to help shrink the tumor and make surgery more effective.
Shenzhen, GuangdongAges 18–79 - NCT05035147RecruitingPhase 4
Albumin-bound paclitaxel plus gemcitabine for advanced pancreatic cancer
This trial studies a chemotherapy combination (albumin-bound paclitaxel and gemcitabine) as first treatment for pancreatic cancer that cannot be removed by surgery. It aims to improve outcomes by testing how well this treatment works in people with locally advanced or metastatic disease.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05037461Recruiting
MR-guided radiation for pancreas tumors in MEN1 patients
This study tests a precise, MRI-guided radiation plan for certain small pancreas neuroendocrine tumors in people with MEN1. It may help control tumor growth when surgery is needed or when remaining small tumor spots are left after prior surgery.
UtrechtAges 18 years+ - NCT05038358Recruiting
Study of immune and chemo resistance in colorectal tumors
This study looks at how the immune system around a colorectal tumor relates to resistance to chemotherapy. You may be able to join if you are having surgery soon for colorectal cancer and have not yet had chemotherapy before surgery.
GrenobleAges 18 years+ - NCT05039411RecruitingPhase 1
Cord stem cell treatment for Crohn’s perianal fistulas
This Phase 1 study tests whether donor umbilical cord stem cells are safe for treating fistulas (abnormal tunnels) near the anus in people with Crohn’s disease. It’s mainly looking at safety, and it may help some people’s symptoms if the approach is workable.
Kuala LumpurAges 18 years+ - NCT05040360RecruitingPhase 2
Chemotherapy after surgery for high-risk pancreatic NET tumors
This Phase 2 trial studies whether giving chemotherapy after surgery can lower cancer recurrence risk in people with high-risk pancreatic neuroendocrine tumors (NETs). It may help you by testing an added treatment after the tumor has been removed.
Anchorage, AlaskaAges 18 years+ - NCT05040464RecruitingPhase 3
Azathioprine or methotrexate added to adalimumab for Crohn’s
This trial compares two medicine options (azathioprine vs methotrexate) when added to adalimumab to treat active Crohn’s disease. It may help determine which add-on works better for people whose Crohn’s is still active despite standard treatments or who can’t take them.
AmiensAges 18 years+ - NCT05041374Recruiting
Study for adults with digestive or liver problems
This study looks at adults who have known or possible problems in the digestive system or liver. It may help patients by offering structured evaluation and follow-up for their condition.
Bethesda, MarylandAges 18–120 - NCT05041478Recruiting
Cold removal method for large colon polyps
This trial compares two cold endoscopic techniques to remove certain large, non-cancerous colon polyps with better control of bleeding and leftover tissue. You may be offered one of the two removal methods during your scheduled colonoscopy.
Westmead, New South WalesAges 18 years+ - NCT05043870RecruitingPhase 4
Testing medicines that calm the immune system in kids with Crohn’s
This trial studies a combination of immune-suppressing treatments for children with Crohn’s disease that is not well controlled. It may help reduce inflammation and improve symptoms if you meet the study’s disease-activity and safety requirements.
Shanghai, Shanghai MunicipalityAges 6–18 - NCT05044689Recruiting
Study to find risk factors for breast and colon cancer
This study is trying to understand what factors might raise the risk of breast cancer and colon (large bowel) cancer. You may be enrolled either if you have a confirmed cancer diagnosis (cases) or if you do not have cancer (controls).
Ile-Ife, Osun StateAges Any age - NCT05046483Recruiting
Blood sugar study after a new heart attack

Fluorescent-guided surgery for liver cancer using GPC3 dye
This trial studies whether a special fluorescent dye that targets GPC3 can help surgeons find liver cancer more clearly during an operation. It may improve how accurately tumor tissue is identified while you have surgery for hepatocellular carcinoma.
Zhuhai, GuangdongAges 18–75 - NCT05049317Recruiting
Check urinary and sexual function after rectal cancer surgery
This study looks at how a specific rectal surgery (laparoscopic total mesorectum excision) affects urinary and sexual function after the operation. It may help patients by tracking what to expect and which factors relate to better recovery.

This trial studies whether using hypnosis during a screening colonoscopy can help people better tolerate the procedure and complete it comfortably. It’s for adults who are scheduled for a routine screening colonoscopy and meet specific safety and communication requirements.
AngersAges 18–100 - NCT05051098Recruiting
Registry for people with hepatitis B infection
This study is a registry, meaning it collects health information from people living with hepatitis B rather than giving a new treatment. It may help researchers better understand different hepatitis B groups and outcomes over time.
HanoverAges 18 years+ - NCT05052671Recruiting
Blood test for residual cancer in resectable pancreatic cancer
This trial studies a blood test that looks for tiny traces of cancer-related DNA (called ctDNA) in people with pancreatic cancer that can be removed with surgery. The goal is to see whether this test can better predict how the cancer behaves and guide treatment decisions around surgery.
