AnderlechtAges 18 years+ - NCT06447064Recruiting
Cancer loyalty card study for early detection
This study looks at whether shopping loyalty card data can help detect cancer earlier. If you have a Tesco Clubcard or Boots Advantage Card, you may be able to join by sharing your purchase history to help researchers find patterns linked to cancer.
LondonAges 18 years+ - NCT07318051Recruiting
Sample collection for cancer research study
This study collects blood and tumor tissue samples from patients with certain untreated cancers to help researchers develop and improve tests. You may be eligible if you have one of the listed cancer types and have not yet started treatment.
Austin, TexasAges 18 years+ - NCT05686226RecruitingPhase 2
Trial tests immune cells targeting HPV-16 cancers
This Phase 2 trial tests an immune-cell treatment (E7 TCR T cells) designed to attack cancers caused by HPV type 16. It may help people whose HPV-16+ cancer has come back or not responded to standard treatment.
Bethesda, MarylandAges 18 years+ - NCT06632886Recruiting
AI study to find cancers from your past CT scans
This study uses artificial intelligence to look at CT scans you've already had (without dye) to try and find signs of several types of cancer early. It may help find cancer sooner when it's easier to treat.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT03755739RecruitingPhase 2/Phase 3
Checkpoint cancer drug given into or near tumors
This trial studies whether giving immunotherapy “checkpoint inhibitor” medicine directly into the tumor area (and/or the artery feeding it), along with a chemotherapy-style drug, can work better for advanced solid tumors. It aims to boost the immune system’s ability to attack cancer while still being safe for people with measurable tumors.
Guanzhou, GuangdongAges 18 years+ - NCT06508307RecruitingPhase 1
A study of an injected virus for advanced solid tumors
This trial tests a new treatment where a virus (GC001) is injected directly into a tumor. The virus is designed to attack cancer cells and may help people with advanced solid tumors that haven't responded to other treatments.
Zhengzhou, HenanAges 18–75 - NCT06880055Recruiting
Shield blood test for colorectal cancer screening
This study is testing the Shield blood test for people at average risk of colorectal cancer. It looks at how well the test works for screening, so you can learn about your risk with a simple blood draw.
Chandler, ArizonaAges 45–81 - NCT06589440RecruitingPhase 2
Study of SR-8541A plus two immunotherapies for advanced colorectal cancer
This trial tests a new drug combination (SR-8541A, botensilimab, and balstilimab) for people with a specific type of metastatic colorectal cancer that is not MSI-high. It aims to see if this combination can help when other treatments have stopped working.
Morristown, New JerseyAges 18 years+ - NCT05534087RecruitingPhase 3
Blood test guided chemo after colon cancer surgery
This study tests whether giving additional (adjuvant) chemotherapy based on a special blood test—circulating tumor DNA (ctDNA)—can lower the risk of colon cancer coming back. It targets people with stage II–III colon cancer whose blood test is positive for minimal residual disease (MRD) after completing standard chemo.
BusanAges 19–75 - NCT07416552RecruitingPhase 1
Study of CEA-PRIT 2.0 for advanced colorectal cancer
This trial tests an experimental drug called CEA-PRIT 2.0 in people whose colorectal cancer has spread and is no longer responding to standard treatments. The goal is to see if it can help shrink tumors or slow the cancer's growth.
Omaha, NebraskaAges 18 years+ - NCT06761287Recruiting
Choosing surgery after chemo for advanced rectal cancer
This study looks at patients with advanced rectal cancer who had treatment (chemotherapy or radiation) before surgery. They want to see if it's safe to avoid surgery in those who had a good response to initial treatment.
BrusselsAges 18 years+ - NCT03064646Recruiting
Preserving tissue in near-complete rectal cancer response
This trial studies whether it’s safe to preserve the rectum (instead of removing it right away) for people with locally advanced rectal cancer who respond very well after pre-treatment radiation and/or chemotherapy. It may help some patients avoid major surgery, but eligibility depends on response seen on exam, scope, and MRI, and on having no spread to distant organs.
Elche, AlicanteAges 18 years+ - NCT06841159RecruitingPhase 2
Personalized radiation plus immunotherapy and chemo for metastatic colorectal cancer
This trial tests a new combination of ultra-precise radiation therapy, immunotherapy, chemotherapy, and targeted therapy for people with metastatic colorectal cancer that has a normal DNA mismatch repair system. The goal is to see if this personalized approach can better control the cancer and improve outcomes.
ShanghaiAges 18–75 - NCT06824688Recruiting
