LleidaAges 18 years+ - NCT06897644RecruitingPhase 3
Comparing two chemotherapy strategies for advanced pancreatic cancer
This study compares two chemotherapy strategies for people with advanced pancreatic cancer who have not yet had treatment. The goal is to see if switching to a different chemotherapy combination (gemcitabine plus nab-paclitaxel) after initial treatment works better than staying on the original chemotherapy (modified FOLFIRINOX).
Aviano, ItalyAges 18 years+ - NCT06898385RecruitingPhase 1
IX001 TCR-T Cells for Advanced Pancreatic Cancer with KRAS G12V
This trial tests a new treatment called IX001 TCR-T cells, which are specially designed immune cells that target a specific mutation (KRAS G12V) found in some pancreatic cancers. It is for people whose cancer has not been controlled by standard chemotherapy.
Guangzhou, GuangdongAges 18–75 - NCT06898398Recruiting
TACE before surgery for large liver cancer
This trial combines a procedure called TACE (which blocks the blood supply to the tumor) with surgery to remove a large liver tumor. It is for people newly diagnosed with a large liver cancer that hasn't spread and can be completely removed with surgery.
Beijing, Beijing MunicipalityAges 18–75 - NCT06898996Recruiting
Stool test study for Lynch syndrome colon screening
This trial tests a new stool-based test (FIT) to see if it can help find colon cancer early in people with Lynch syndrome. You will collect stool samples at home and complete surveys before your regular colonoscopy.
Chicago, IllinoisAges 20–80 - NCT06899152Recruiting
New tests to track liver health during radiation for liver cancer
This study tests new blood tests and MRI scans to see how well your liver works during radiation therapy for liver cancer. It may help doctors better plan treatment and monitor your liver health.
The Bronx, New YorkAges 18 years+ - NCT06899854Recruiting
Collecting blood and tissue from patients with liver cancer
This study collects blood and tumor tissue samples from people with primary liver cancer who are starting their first treatment (systemic therapy or surgery). The samples help researchers learn more about these cancers and how to improve future treatments.
Pavia, PaviaAges 18–90 - NCT06900491Recruiting
Irritable Bowel Syndrome Regional Cohort Study
This study follows a group of people with irritable bowel syndrome (IBS) to learn more about the condition. You may join if you have been diagnosed with IBS and have had normal routine blood tests.
AmiensAges 18 years+ - NCT06903325Recruiting
Monitoring DNA markers in blood to predict colorectal cancer return after surgery
This study tests if a simple blood test can detect early signs of colorectal cancer coming back after surgery to remove cancer spread in the abdomen. It may help patients avoid unnecessary treatments and catch recurrence sooner.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06903858RecruitingPhase 2
Toripalimab plus celecoxib for dMMR/MSI-H colorectal cancer
This trial tests whether combining toripalimab (an immunotherapy) with celecoxib (an anti-inflammatory drug) can shrink locally advanced colorectal tumors that have specific genetic features (dMMR or MSI-H). It aims to help people who haven't had any prior treatment for their colorectal cancer.
Guangzhou, GuangdongAges 18 years+ - NCT06904170RecruitingPhase 2/Phase 3
Immunotherapy with or without liver artery chemo for liver cancer
This trial tests adding a targeted chemo infusion into the liver's main artery to two immunotherapy drugs for liver cancer. It may help patients whose cancer has spread within the liver and can't be removed by surgery.
BordeauxAges 18 years+ - NCT06904196RecruitingPhase 2
Lenvatinib with or without internal radiation for TACE-resistant liver cancer
This trial compares two treatments for liver cancer (HCC) that has stopped responding to TACE. One group gets lenvatinib (a targeted therapy pill) plus SIRT (internal radiation beads placed in the liver), and the other gets lenvatinib alone. The goal is to see which combination works better.
Guangzhou, GuangdongAges 18–75 - NCT06904183RecruitingPhase 2
Study of lenvatinib, sintilimab, and DEB-TACE with or without HAIC for large liver cancer with portal vein tumor thrombus
This trial tests a combination of two drugs (lenvatinib and sintilimab) plus a liver-directed treatment (DEB-TACE) with or without another liver treatment (HAIC) for people with large liver cancer (over 7 cm) that has spread into the main blood vessel of the liver. The goal is to see if adding HAIC helps shrink the cancer more effectively.
Guangzhou, GuangdongAges 18–75 - NCT06904677Recruiting
Urine test to predict colorectal cancer treatment response
This study uses a special urine test to see if it can predict how well colorectal cancer responds to treatment. If you are about to start treatment before surgery, you may be able to join by giving urine samples before and during therapy.
