Comparing two ways to measure liver pressure
This study compares a newer, less invasive method using an endoscope (EUS-PPG) with a standard catheter method (HVPG) to measure liver pressure in people with advanced liver disease. The goal is to see if the newer method is equally accurate and safer.
Prague, BohemiaAges 18–75 - NCT07425054RecruitingPhase 2
Chemoradiation with or without immunotherapy for anal cancer
This trial tests whether adding an immunotherapy drug (retifanlimab) to standard chemoradiation improves outcomes for people with locally advanced anal cancer. The treatment is adjusted based on HPV DNA levels in your blood.

CAR-NK cell therapy for advanced pancreatic cancer
This trial tests a new treatment using immune cells (CAR-NK cells) to fight pancreatic cancer that has spread or come back. It may be an option if standard treatments have stopped working, were not tolerated, or were refused.
ShanghaiAges 18–75 - NCT07426835Recruiting
Comparing two hernia prevention methods in robotic esophageal cancer surgery
This trial compares two ways of closing the diaphragm during robotic esophageal cancer surgery to see if one reduces the chance of a hernia later. If you're having a robotic esophagectomy for cure, you may be able to join.

Selenium for Ulcerative Colitis Patients on Biologics
This trial tests whether taking selenium supplements can help people with moderate to severe ulcerative colitis that is being treated with advanced therapies (biologics). The goal is to see if selenium can improve symptoms and reduce inflammation.
Chicago, IllinoisAges 18–85 - NCT07427537Recruiting
Studying nerve damage from chemotherapy in colorectal and lung cancer patients
This study looks for small molecules in the blood that might predict nerve damage caused by certain chemotherapies. If you have colorectal or lung cancer and are starting a specific chemo plan, this trial could help researchers understand why some people get nerve problems and others don't.
Clermont-FerrandAges 18 years+ - NCT07427901Recruiting
Quality of life in colorectal cancer survivors
This study looks at how colorectal cancer and its treatment affect your daily life and well-being. It aims to help doctors better support patients like you during and after treatment.
LjubljanaAges 18 years+ - NCT07428356Recruiting
Sound waves for liver tumors
This study tests a new, noninvasive treatment called histotripsy that uses sound waves to destroy small liver tumors. It is for people whose liver cancer hasn't spread much and who haven't had success with or can't have surgery or other standard treatments.
SingaporeAges 21–99 - NCT07429864Recruiting
Bulevirtide for hepatitis D: bile acids and gut bacteria
This study looks at how Bulevirtide, a treatment for hepatitis D, affects bile acids and gut bacteria. It may help patients with chronic HDV and stable liver disease who are already on HBV therapy.
RomaAges 18 years+ - NCT07431983Recruiting
IBUS vs colonoscopy and enterography for UC and CD
This study compares a newer, possibly greener imaging method (IBUS) with standard colonoscopy and enterography for people with ulcerative colitis (UC) or Crohn's disease (CD). The goal is to see if IBUS is as helpful and produces less waste or carbon emissions.
Hyderabad, TelanganaAges 18–80 - NCT07432295RecruitingPhase 2
Givastomig plus nivolumab and chemo for advanced stomach cancer
This trial tests a new drug, givastomig, combined with standard immunotherapy (nivolumab) and chemotherapy for people with advanced stomach, gastroesophageal junction, or esophageal cancer. It is for people whose tumors have certain markers (CLDN18.2 and PD-L1) and who have not had treatment for advanced disease.
Goodyear, ArizonaAges 18 years+ - NCT07432399RecruitingPhase 2
Lidocaine or dexamethasone before colon cancer surgery
This study tests whether giving lidocaine or a high-dose steroid before colon cancer surgery can improve immune function and recovery. The goal is to find a simple, safe way to help your body respond better during surgery.
LjubljanaAges 18 years+ - NCT07432347Recruiting
Decoding liver cancer immune evasion with advanced testing
This trial studies liver cancer tissue to understand how the tumor hides from the immune system. The goal is to use this knowledge to improve future treatments.
Milan, LombardyAges 18 years+ - NCT07432633RecruitingPhase 1/Phase 2
Imaging scan to detect cancer-linked protein in several tumor types
This trial tests a new PET scan tracer that targets a protein found on certain cancer cells. It may help doctors better see and understand tumors in people with colorectal, gastric, pancreatic, lobular breast, or ovarian cancer.
