Liver transplant vs chemotherapy for colon cancer liver spread
This trial compares liver transplantation to standard chemotherapy for people with colon or rectal cancer that has spread to the liver but cannot be removed surgically. It looks at whether transplant can help patients live longer or better than chemotherapy in the right patients.
OsloAges 18 years+ - NCT01479608Recruiting
Liver transplant for colon or rectal cancer liver spread
This trial studies whether a liver transplant can help people with colon or rectal cancer that has spread to the liver (but not elsewhere). It aims to improve outcomes by removing the diseased liver when the cancer has responded to chemotherapy and can still be controlled.
OsloAges 18 years+ - NCT06244225RecruitingPhase 2
Triple therapy for advanced liver cancer (HAIC + sintilimab + donafenib)
This trial tests a combination of three treatments for advanced liver cancer that cannot be removed by surgery: a targeted oral drug (Donafenib), an immunotherapy (Sintilimab), and a type of chemotherapy given directly into the liver artery. The goal is to see if this triple therapy works better than current options for people who have not had any prior cancer treatment.
Wuhan, HubeiAges 18 years+ - NCT03675672RecruitingPhase 4
Preventing repeat bleeding from stomach or upper gut ulcers
This trial studies medicines to help stop bleeding from coming back after you’ve had an “idiopathic” stomach/upper gut ulcer bleed. It may help by reducing ulcer re-bleeding risk in people who don’t have common causes like H. pylori or common ulcer-triggering drugs.
Hong KongAges 18 years+ - NCT03809728Recruiting
Finding blood tests linked to outcomes in Crohn’s and colitis
This study looks for “biomarkers” (lab markers, like substances in blood or tissue) that may predict how Crohn’s disease or ulcerative colitis will go and how patients may respond. It may help doctors choose better monitoring or treatments in the future.
Vandœuvre-lès-NancyAges 18 years+ - NCT05515315RecruitingPhase 2
Immunotherapy plus chemo then chemoradiation for esophageal cancer
This Phase 2 study tests whether adding tislelizumab (an immunotherapy drug) to chemotherapy before a combined course of chemotherapy and radiation can better treat locally advanced, non-surgable esophageal squamous cell cancer. It’s for adults who cannot have surgery and may help shrink the cancer and improve control of the disease.
Fuzhou, FujianAges 18–70 - NCT06236568Recruiting
Liver transplant study for liver cancer patients
This study tests a special way to preserve donated livers before transplant to see if it reduces the chance of liver cancer coming back after surgery.
Modena, MOAges 18 years+ - NCT06245330RecruitingPhase 1/Phase 2
Study of AST-001 for advanced solid tumors
This trial is testing a new drug called AST-001 for people with advanced solid tumors (including pancreatic cancer) that have not responded to standard treatments. The study aims to find the right dose and see how well the drug works.
Changchun, JinlinAges 18–70 - NCT04282044RecruitingPhase 1
CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.
Scottsdale, ArizonaAges 18 years+ - NCT04471493Recruiting
Study of children’s common infections in a clinic program
This trial is for children under 16 who have one of several common infections seen in outpatient or clinic visits. It aims to better study and manage these illnesses using a specific clinical documentation software.
CréteilAges 1 day–16 years - NCT05912075RecruitingPhase 1
New pre-surgery radiation plus ASTX660 for rectal cancer
This early-phase trial tests adding ASTX660 (a new drug) to pre-surgery radiation for locally advanced rectal cancer. It aims to improve control of the tumor before surgery, making it more likely that the surgeon can remove it with clear margins.
Lyon, RhöneAges 18 years+ - NCT05221398Recruiting
Immunotherapy after liver cancer surgery
This trial tests whether giving immunotherapy after surgery to remove liver cancer can help lower the risk of the cancer coming back. It may be an option for people who have certain risk factors for recurrence.
Nanning, GuangxiAges 18–75 - NCT07872514Enrolling by invitation
Personalized probiotics for irritable bowel syndrome
This study tests whether a probiotic treatment designed specifically for you can help ease your irritable bowel syndrome (IBS) symptoms. If you make it into the study, you'll get a treatment plan tailored to your gut and your symptoms.
Hamilton, OntarioAges 18–70 - NCT02308917Recruiting
Canadian children's inflammatory bowel disease study
This study follows children with inflammatory bowel disease (IBD) to learn more about the disease and improve care. It may help doctors understand how to treat Crohn's disease, ulcerative colitis, or IBD that doesn't fit either diagnosis.
Calgary, AlbertaAges 2–17 - NCT07855640Recruiting
Immunotherapy plus chemo for advanced stomach cancer with fluid in belly
This trial tests a new combination for advanced stomach cancer that has spread and caused fluid buildup in the belly (malignant ascites). It combines an immunotherapy drug (anti-PD-1) with standard chemotherapy and a targeted chemotherapy given directly into the belly to see if it can shrink the cancer and help you feel better.
Hangzhou, ZhejiangAges 18–75 - NCT07173387RecruitingPhase 2
Radiation plus chemo for locally advanced pancreatic cancer
This trial combines focused radiation with a chemotherapy drug combo to help shrink or control locally advanced pancreatic cancer. If it works, this treatment might make the tumor smaller and improve quality of life.
Jinan, ShandongAges 18–75 - NCT06254521RecruitingPhase 2
Tislelizumab plus chemo before surgery for MSS rectal cancer
This trial tests a combination of an immunotherapy drug (tislelizumab) plus chemotherapy before surgery for people with a specific type of rectal cancer that has not spread to other organs. The goal is to see if this approach can shrink the tumor more effectively than standard treatment.
Nanning, GuangxiAges 18 years+ - NCT05988814RecruitingPhase 2
FOLFIRINOX3 for advanced pancreatic cancer
This trial tests a stronger version of FOLFIRINOX chemotherapy for people with pancreatic cancer that cannot be removed by surgery or has spread to other parts of the body. It aims to see if the new dosing schedule works better and is safe.
DijonAges 18 years+ - NCT03222895Recruiting
Mapping lymph node spread in resectable esophageal cancer
This study looks at how esophageal (or esophagus-stomach junction) cancer spreads to nearby lymph nodes. Results may help doctors understand where cancer cells are likely to be, potentially improving future surgery planning.
Houston, TexasAges 18 years+ - NCT05007132RecruitingPhase 2
First-line metastatic colon or rectal cancer study with targeted drugs
This Phase 2 trial compares two treatment combinations as a first treatment for metastatic (spread) colon or rectal cancer. It looks to see whether one combo works better or is safer than the other.
BerlinAges 18 years+ - NCT06057350Recruiting
Surgery versus endoscopy for early colon cancer with uncertain margins
This trial compares surgery versus an endoscopic procedure for people who had a colon polyp removed but some cancer cells may still be present at the edges. The goal is to see which approach leads to better outcomes and fewer side effects for early-stage colon cancer.
Oslo, AkershusAges 40 years+ - NCT07872722RecruitingPhase 2
Study of two immunotherapies plus chemotherapy before surgery for stomach cancer
This trial tests a new approach for stomach cancer that hasn't spread. You'd get a combination of an investigational drug targeting a specific protein on cancer cells, an immunotherapy that helps your immune system fight cancer, and standard chemotherapy before surgery. The goal is to see if this makes the tumor shrink more and improves outcomes.
SaitamaAges 18 years+ - NCT04886635Recruiting
Surgery timing after chemoradiation for esophageal cancer
This study looks at whether having surgery at the right time after chemoradiation improves outcomes for people with esophageal cancer. You might qualify if you have had (or are planning) chemoradiation and then are going to have surgery to remove the tumor.
Rotterdam, South HollandAges 18 years+ - NCT07873606Recruiting
Sound wave treatment for advanced pancreatic cancer
This trial tests a new non-invasive treatment that uses sound waves to break up cancer cells in the pancreas. It is for people whose pancreatic cancer cannot be removed by surgery and who are well enough for anesthesia.
