Prevention and early detection for people at high cancer risk
This study looks at surveillance (watching closely), prevention, and early “interception” steps to lower the chance that cancer will develop or be found later. It is for people with genetic risk, past cancer treatment exposures, strong family history, or certain early pre-cancer or high-risk conditions.
Boston, MassachusettsAges Any age - NCT06560021Enrolling by invitation
Random biopsies in inflammatory bowel disease surveillance
This trial looks at whether taking random biopsies during a routine colonoscopy is helpful for people with inflammatory bowel disease (IBD) who are at risk for colon cancer. It aims to understand if random biopsies can detect early signs of cancer or pre-cancer.
Birmingham, AlabamaAges 18 years+ - NCT07740382Recruiting
Pain block comparison for recovery after liver surgery
This study compares two types of pain-relieving nerve blocks used during liver surgery to see which one helps you breathe better and recover more comfortably after the operation.
Alexandria, Sbein-ElkomAges 18–75 - NCT07519655RecruitingPhase 1
New Cancer Drug Treatment for Advanced Lung, Esophageal, or Skin Cancer
This study tests a new drug called PF-08046033 in people with advanced lung cancer (NSCLC), esophageal cancer (ESCC), or melanoma (skin cancer) that has spread or can't be surgically removed. The drug targets a specific protein to help slow or stop cancer growth.
Denver, ColoradoAges 18 years+ - NCT07331857Recruiting
Testing a new device for esophagus treatment
This study tests a new device (Digma System) for treating Barrett's esophagus and other esophageal conditions. It involves a short procedure during an endoscopy or surgery to remove abnormal tissue.
BrnoAges 18–70 - NCT07401303Recruiting
Studying a new way to reduce risks during early stomach cancer surgery
This trial tests a technique called full-time RDI during ESD (a minimally invasive procedure to remove early stomach cancer). The goal is to see if it can lower the chance of serious side effects and shorten the procedure time. If you are scheduled for this surgery and meet the health requirements, you may be able to join.
Xi'an, ShaanxiAges 18–75 - NCT07440290RecruitingPhase 2/Phase 3
Dabrafenib and trametinib for BRAF V600 cancers
This trial tests two targeted drugs (dabrafenib and trametinib) for patients whose cancer has a specific change in the BRAF gene called V600. These drugs work together to block signals that help the cancer grow. The trial is for children, teenagers, and adults with many types of cancer, except for a few common ones that already have approved treatments.
BelfastAges 1 year+ - NCT07157033RecruitingPhase 1/Phase 2
Testing XER-001 with radiation for advanced pancreatic cancer
This trial tests a new way to deliver a drug called amifostine (XER-001) alongside intense radiation therapy (SBRT) for people with locally advanced pancreatic cancer that can't be surgically removed. The goal is to see if it's safe and effective at protecting healthy tissue while targeting the tumor.
