BeijingAges 18 years+ - NCT06425133RecruitingPhase 2
Regorafenib plus low-dose chemo for advanced colorectal cancer
This trial tests a combination of regorafenib (a targeted pill that cuts off blood supply to tumors) with a low-dose, continuous chemotherapy regimen for people whose colorectal cancer has spread and is no longer responding to standard treatments. The goal is to see if this mix can slow or stop the cancer's growth.
AuxerreAges 18 years+ - NCT06747481Recruiting
Predicting nerve invasion in pancreatic cancer
This study looks at two simple blood tests (neutrophil-to-lymphocyte ratio and CA 19.9) to see if they can predict whether the cancer has spread to nearby nerves in people with pancreatic cancer who have had surgery. This could help doctors plan better treatment.
Las Palmas de Gran Canaria, Las PalmasAges Any age - NCT04890171Recruiting
Endoscopic removal vs surgery for early stomach cancer type
This trial compares two ways to treat early stomach cancer: removing it through an endoscope versus doing an operation. It’s meant for a specific stomach-cancer type (undifferentiated) that has not spread, to see which approach may be better.
Goyang-si, Gyeonggi-doAges 19–75 - NCT06746194Recruiting
PET scan to check treatment response in advanced liver cancer
This trial uses a special PET scan (68Ga-FAPI) to see how well systemic therapy is working in people with advanced liver cancer that can't be removed by surgery. The goal is to find a better way to measure treatment effectiveness.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06746480RecruitingPhase 2
Study of VG161 for advanced bile duct cancer
This trial tests a new medicine called VG161 for people with advanced intrahepatic cholangiocarcinoma (a type of bile duct cancer) that has stopped responding to or could not be tolerated after at least one prior treatment. It is given by injection into the tumor, and the study wants to see if it can help shrink or control the cancer.
Hangzhou, ZhejiangAges 18–75 - NCT04214990RecruitingPhase 3
Aspirin after early stomach precancer or early cancer removal
This trial tests whether taking aspirin after endoscopic removal of an early stomach condition can lower the chance of the cancer coming back or progressing. You may be considered if your early stomach findings were fully removed and you’re able to avoid certain medications that raise bleeding risk.
BusanAges 19–70 - NCT05501379Recruiting
Track activity in cancer patients during treatment
This study compares how physical activity answers on a questionnaire match what a motion tracker measures. It may help researchers understand activity levels in people with lymphoma, colorectal, or pancreatic cancer during treatment.
GreifswaldAges 18 years+ - NCT05894694RecruitingPhase 4
Testing Compound Kushen injection for advanced colon cancer survival
This trial studies whether Compound Kushen injection can improve survival in people with advanced colorectal cancer. It’s aimed at people starting first-line treatment, and only includes certain cancer and health situations to keep results clear.
BeijingAges 18 years+ - NCT07542002RecruitingPhase 2
Chemotherapy and Radiation for Pancreatic Cancer Before Surgery
This trial tests a combination of four drugs (liposomal irinotecan, 5-fluorouracil, oxaliplatin, and adebrelimab) given with radiation therapy before surgery for pancreatic cancer that can be surgically removed or is borderline removable. The goal is to shrink the tumor and improve the chances of successful surgery.
NingboAges 18–75 - NCT06430658RecruitingPhase 2
Combination treatment before surgery for unresectable esophageal cancer
This trial tests a combination of treatments given before surgery to shrink tumors in patients with esophageal cancer that is considered too advanced for immediate surgery. The goal is to make surgery possible and improve outcomes.
BeijingAges 18–75 - NCT07540312Recruiting
Compression System for Moderate to Severe Irritable Bowel Syndrome
This trial tests a wearable compression device designed to help people with moderate to severe irritable bowel syndrome (IBS). The device applies variable pressure to the abdomen and may help reduce symptoms like abdominal pain, bloating, and bowel irregularities.
Kissimmee, FloridaAges 18–60 - NCT07540572RecruitingPhase 1
Testing IDE574 safety and effectiveness in advanced solid tumors
This early-stage trial tests a new drug called IDE574 to see if it is safe and effective in treating advanced cancers that have spread or stopped responding to standard treatments. The trial focuses mainly on hormone-receptor positive breast cancer, but also includes lung, prostate, and colorectal cancers.
Plantation, FloridaAges 18–99 - NCT07542041Recruiting
Pancreatic Cancer Detection Using Advanced Tissue Analysis
This study tests a new way to analyze tiny samples of pancreatic tissue taken during a biopsy to better detect cancer. The method uses special technology to examine the physical properties of cells, which may help doctors diagnose pancreatic cancer more accurately.
Tampa, FloridaAges 18 years+ - NCT07541261Recruiting
Real-World Study of Guselkumab for Ulcerative Colitis and Crohn's Disease
This study tracks how guselkumab (a biologic medication that reduces inflammation) works in patients with moderate-to-severe ulcerative colitis or Crohn's disease in Saudi Arabia. Researchers want to understand how the medication helps patients in everyday clinical practice, not in a controlled research setting.
JeddahAges 18 years+ - NCT07539311RecruitingPhase 2
Testing Rina-S for Advanced Gastrointestinal Cancers
This study tests a new drug called Rina-S in people with advanced gastrointestinal cancers (like stomach, colon, or pancreatic cancer) that have spread or cannot be surgically removed. The drug is designed to help slow or stop cancer growth in people whose cancer has gotten worse despite recent treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT06613165Recruiting
Short vs long treatment for stage II-III rectal cancer with dMMR
This trial tests how long you need a PD-1 immunotherapy before surgery for a specific type of rectal cancer (dMMR/MSI-H). It looks at whether a shorter or longer course works best. This could mean fewer side effects and a quicker path to surgery.
Xi'an, ShaanxiAges 18–80 - NCT06749015Recruiting
Study for BRAFV600E Mutant Metastatic Colorectal Cancer
