Perioperative immunotherapy plus chemotherapy for resectable throat cancer
This trial studies whether adding camrelizumab (an immune system drug) to chemotherapy before and around surgery can improve outcomes for people with resectable esophageal squamous cell carcinoma (ESCC). If you are eligible, treatment is given around the time of planned surgery to remove the tumor and lymph nodes.
Zhengzhou, HenanAges 18–80 - NCT05182463RecruitingPhase 4
Peginterferon test for inactive chronic hepatitis B
This trial studies whether pegylated interferon can help people with inactive chronic hepatitis B stay stable or improve outcomes. You may qualify if your virus levels and liver blood tests are currently low and you’ve never used antiviral treatments.
Guangzhou, GuangdongAges 18–60 - NCT05184790Recruiting
Using imaging during radiation therapy to improve AI planning
This study tests how well an artificial intelligence system can use special X-ray images taken during certain radiation treatments to improve care. You may qualify if you’re having radiation for specific conditions and your treatment center uses the required imaging steps.
Saint Leonards, New South WalesAges 18 years+ - NCT05184400Recruiting
Find new blood or tumor markers for bile duct and gallbladder cancer
This study looks for new ways to measure cancer-related “biomarkers” (signals in blood or tumor samples) in people with bile duct cancer or gallbladder cancer. The goal is to improve how these cancers are identified and tracked, which could help doctors make better treatment decisions.
Herlev, CopenhagenAges 18 years+ - NCT05184803RecruitingPhase 2
Pre-surgery chemo for advanced stomach cancer with lymph spread
This Phase 2 study tests a combination chemotherapy regimen given before surgery for stomach cancer that cannot be fully removed (unresectable), including spread to lymph nodes. The goal is to shrink the cancer and improve control with a well-known set of medicines given in a specific order.
Seoul, SeoulAges 19 years+ - NCT05185245Recruiting
Liver transplant for colorectal cancer spread to the liver
This study looks at whether a liver transplant can help people whose colorectal cancer has spread to the liver but cannot be removed by surgery. It also checks whether certain cancer features, treatment history, and blood/health status make transplant safer or more effective.
BolognaAges 18–73 - NCT05185505RecruitingPhase 4
Atezolizumab and bevacizumab before liver transplant for liver cancer
This trial tests giving atezolizumab plus bevacizumab before liver transplant in people with hepatocellular carcinoma (HCC) that is too advanced to be listed within the “Milan criteria,” but still transplant-eligible. The goal is to control the cancer outside the transplant period and improve transplant outcomes.
Houston, TexasAges 18 years+ - NCT05186116Recruiting
Liver transplant for colon cancer that cannot be removed
This trial studies whether liver transplant (rather than removing the liver tumors) can help some people with colon or rectal cancer spread to the liver. It’s meant for people whose cancer has responded or stayed controlled on standard treatments and who have no cancer outside the liver.
Modena, MOAges 18–77 - NCT05185739RecruitingPhase 2
Pembrolizumab and lenvatinib before liver surgery for resectable cancer
This trial tests whether giving pembrolizumab (an immune therapy) and lenvatinib (a targeted pill) before planned liver surgery can improve outcomes for people with certain types of operable hepatocellular carcinoma (HCC). It’s meant for tumors that can be removed with curative intent, but still carry a risk of coming back.
BirminghamAges 18 years+ - NCT05185609Recruiting
Tests anal function in people with inflammatory bowel disease
This study checks how well the anal area works in people with inflammatory bowel disease (IBD), even when your bowel disease is “in remission” but you may still have symptoms. It may help doctors better understand the cause of ongoing problems and guide future care.
ÖrebroAges 18–65 - NCT05186623Recruiting
Personalized prediction for ulcerative colitis treatment response
This study builds a prediction model to estimate how people with ulcerative colitis may respond to certain medicines. It may help doctors choose the most effective treatment sooner.
SeoulAges 18–79 - NCT05187312Recruiting
Registry for advanced endoscopy procedures
This study is a registry that collects information about people who need an endoscopy procedure. It may help doctors learn which approaches work best and improve care over time.
StockholmAges 18 years+ - NCT05187182RecruitingPhase 1
Testing a new cancer drug with FOLFOX and immune therapy
This Phase 1 study tests CA-4948 given with standard chemotherapy (FOLFOX) and an immune therapy (an immune checkpoint inhibitor, similar to PD-1). It’s for people with advanced stomach or esophageal cancer that can’t be removed by surgery, to see how well the treatment works and whether it’s safe.
St Louis, MissouriAges 18 years+ - NCT05187091RecruitingPhase 3
Radiation plan that tries to protect swallowing organs
