Oral paclitaxel for advanced GIST after other treatments fail
This trial tests an oral form of paclitaxel (a chemotherapy drug) for people with advanced gastrointestinal stromal tumor (GIST) that has stopped responding to or caused side effects with imatinib, sunitinib, and regorafenib. It aims to see if this treatment can help when other options have run out.
Seoul, SongpaguAges 20 years+ - NCT06326502RecruitingPhase 1
A study of ETN101 for advanced liver cancer
This trial tests an experimental oral drug (ETN101) for adults with advanced liver cancer (hepatocellular carcinoma) that has gotten worse after standard treatments or can't be treated with standard therapy. It aims to see if the drug is safe and effective.
SeoulAges 19–65 - NCT06326736RecruitingEarly Phase 1
mRNA vaccine after surgery for pancreatic cancer
This trial tests a personalized mRNA vaccine (made from your tumor's unique markers) combined with standard chemotherapy after surgery for pancreatic cancer. The goal is to see if the vaccine can help prevent the cancer from coming back.
Nanjing, JiangsuAges 18–75 - NCT06326879Recruiting
Comparing early vs late onset colorectal cancer
This study compares patients diagnosed with colorectal cancer at a younger age (under 50) to those diagnosed later in life. By looking at tissue samples and patient surveys, researchers hope to understand differences in the disease and improve care for all ages.
Rozzano, MIAges 18 years+ - NCT06326892Recruiting
Natural opening extraction in low rectal cancer surgery
This trial looks back at patients who had surgery for low rectal cancer using a technique where the removed tissue is taken out through a natural opening (like the anus) instead of through a separate cut in the belly. It aims to see how well this approach works.
Rozzano, MIAges 18 years+ - NCT06327269RecruitingEarly Phase 1
Targeted therapy after liver transplant for high-risk liver cancer
This trial tests a targeted therapy (lenvatinib) given after a living-donor liver transplant to prevent high-risk liver cancer from coming back. It is for people whose cancer is aggressive or did not respond well to previous treatments.
Kaohsiung CityAges 18–75 - NCT06327568Recruiting
Screening for anal cancer and precancer with a new HPV test
This study tests how well a special HPV test (called BD Onclarity™) can find anal cancer or precancer. It is for people at high risk or with known anal abnormalities, and aims to improve early detection.
MilanAges 18 years+ - NCT06328361Recruiting
Avoiding surgery for rectal cancer after good response to treatment
This trial tests a new approach: after initial treatment (like chemo or radiation), people with rectal cancer who have a complete response may be able to avoid surgery. Instead, they are monitored closely to see if the cancer stays away.
TallinnAges 18 years+ - NCT06329869RecruitingPhase 2
A study of sacituzumab govitecan for advanced esophageal cancer
This trial tests a drug called sacituzumab govitecan for people with advanced esophageal squamous cell carcinoma that has already been treated with chemotherapy and immunotherapy. The drug targets a protein called Trop-2 on cancer cells to try to stop tumor growth.
TaipeiAges 18 years+ - NCT06329544Recruiting
Study of a high-fructose diet and gut health
This trial tests how a high-fructose diet affects your gut bacteria and overall metabolic health. It is for people who already know they don't absorb fructose well (fructose malabsorbers) and want to understand how this sugar impacts their body.
New York, New YorkAges 25–45 - NCT06330441Recruiting
Pancreatic cancer screening for high-risk groups
This study screens people at high risk for pancreatic cancer using imaging tests. It aims to catch cancer early in those with certain genetic conditions or strong family history.
BrnoAges 18 years+ - NCT06330688Recruiting
Ultrasound-guided gallbladder drainage study

Combination therapy for infiltrative liver cancer
This trial tests a three-drug combination for a specific type of liver cancer called infiltrative hepatocellular carcinoma. It combines a liver-directed chemotherapy infusion (HAIC) with two oral and intravenous drugs (lenvatinib and a PD-1 inhibitor) to see if it works better than lenvatinib alone.
Beijing, Beijing MunicipalityAges 18–75 - NCT06333392Recruiting
Underwater colonoscopy for better cancer screening
