Study of tislelizumab plus chemo for advanced esophageal cancer
This trial tests different schedules of tislelizumab (an immunotherapy drug) combined with chemotherapy for Japanese patients with advanced esophageal squamous cell carcinoma that cannot be removed by surgery or has spread. It aims to find a better way to give these treatments together.
Yokohama, KanagawaAges 18 years+ - NCT07733674RecruitingPhase 1
Testing a new imaging agent for brain and pancreatic tumors
This early-phase study tests a new imaging agent that may help see certain solid tumors (like brain cancer or pancreatic cancer) more clearly. You will receive a single injection of a radioactive tracer, then have several scans over a few days to see where the tracer goes and how long it stays.
Houston, TexasAges 18 years+ - NCT06452745Recruiting
Early colon cancer detection using a blood test
This study uses a simple blood test to find early signs of colorectal cancer in people who already had a positive stool test. If it works, it could help avoid unnecessary colonoscopies in the future.
Reus, TarragonaAges 50–70 - NCT06624098Recruiting
Early TIPS for Advanced Liver Cancer with Vein Blockage
This study tests whether placing a small tube (TIPS) early in people with advanced liver cancer and a vein blockage helps their other treatments work better. It is for patients who are already taking lenvatinib and immunotherapy.
Beijing, Beijing MunicipalityAges 18–75 - NCT05196334Recruiting
Testing pancreatic lab samples to guide future treatments
This study uses small pancreatic cancer samples grown in the lab to understand which treatments may work best for people with pancreatic cancer. It may help researchers better “profile” tumors so standard care can be matched to the most effective options.
Herlev, CopenhagenAges 18 years+ - NCT04571294Recruiting
Removing lymph nodes during Whipple surgery for pancreatic cancer
This study looks at removing certain lymph nodes near the aorta while doing a standard Whipple operation for pancreatic head cancer. The goal is to see whether this approach can improve how well doctors manage the cancer spread.
Rozzano, Italy/MilanAges 18 years+ - NCT05738421Recruiting
Tests a breathing tube cap and safe swallowing after throat surgery
This study looks at whether using a capped breathing tube for about 48 hours is safe and whether it fits with swallowing training after head and neck surgery. It may help people transition more safely from a breathing tube back toward normal swallowing and breathing.
RomaAges 18–70 - NCT07726368RecruitingPhase 1
Study of ECC4703 with sulfasalazine and pitavastatin
This early-phase study tests how a new drug (ECC4703) works in the body when taken with two other common medications (sulfasalazine and pitavastatin). Healthy volunteers are needed to help researchers understand potential drug interactions and safety.
Melbourne, VictoriaAges 18–65 - NCT07732400RecruitingPhase 1/Phase 2
Gene therapy for MASH (fatty liver disease)
This trial tests an experimental gene therapy (VV-14303) given as a single injection into the muscle to treat MASH, a common type of fatty liver disease with inflammation. The study will check if the treatment is safe and helps improve liver health.
Chandler, ArizonaAges 18–75 - NCT07728487RecruitingPhase 1
AT-587 safety study in healthy volunteers
This trial tests a new medication called AT-587 in healthy people to see if it is safe and how the body processes it. You may help by participating if you are in good health and meet the basic requirements.
EdegemAges 18–65 - NCT07730021RecruitingPhase 1/Phase 2
New drug for advanced solid tumors
This trial tests a new drug called ASP388B, given alone or with standard treatments, for people with certain advanced solid tumors that have stopped responding to therapy. It may help shrink tumors or slow their growth.
Lake Success, New YorkAges 18 years+ - NCT06627634Recruiting
Surgery for stomach cancer that spread to the liver
