Predictors of complications in laparoscopic surgery
This study looks at factors that may predict complications after laparoscopic surgery (minimally invasive surgery with a camera) when the patient is tilted head-down (Trendelenburg position). It focuses on surgeries lasting longer than 2 hours.
Jerusalem, YerushalaimAges 18 years+ - NCT07249333Recruiting
Complications after pre-surgery radiation for colorectal cancer
This trial looks at side effects and recovery (complications) after chemotherapy or radiation given before surgery for colorectal cancer. It includes people who are somewhat frail (scores 2–4), to see how they do after the operation.
Kamenitz, VojvodinaAges 18 years+ - NCT07249463RecruitingPhase 2
Testing a new drug for cryptosporidium infection in healthy adults
This trial tests a new drug, EDI048, to see how well it works and how safe it is for treating cryptosporidium infection. It is for healthy volunteers who will be intentionally exposed to the infection under controlled conditions.
Baltimore, MarylandAges 18–50 - NCT07244705RecruitingPhase 1/Phase 2
Study of ABT-301 plus tislelizumab and bevacizumab for advanced colorectal cancer
This trial tests a new drug combination (ABT-301, tislelizumab, and bevacizumab) for people with a specific type of advanced colorectal cancer that has not responded to at least two prior treatments. It aims to see if this combination can help shrink tumors or slow the disease.
Liverpool, New South WalesAges 18 years+ - NCT07244835RecruitingPhase 1
A study of DEG6498 for advanced solid tumors
This trial tests a new drug, DEG6498, for people with advanced solid tumors that have not responded to other treatments. It may be an option if your cancer has a BRAF mutation or is a type of liver cancer called HCC.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07242248Recruiting
Real-world study of guselkumab for Crohn's and colitis
This study looks at how well guselkumab works in real life for people with moderate-to-severe Crohn's disease or ulcerative colitis. It tracks patients in the UK who start guselkumab as part of their normal care.
HarrowAges 18 years+ - NCT07240896RecruitingEarly Phase 1
Testing a new mRNA therapy for Wilson disease
This trial tests an experimental mRNA treatment (DSL101) for adults with Wilson disease. It's for people whose condition is stable on current therapy and who have certain genetic markers. The goal is to see if the new treatment can help the body process copper better and reduce the need for standard medicines.
Hefei, AnhuiAges 18 years+ - NCT06905015Recruiting
Comparing two methods to reduce blood loss during open liver surgery
This trial tests whether using stroke volume variation (SVV) is better than central venous pressure (CVP) to guide fluid management and reduce bleeding during open liver surgery. It aims to find a safer way to manage fluids during the operation.
Chiang Mai, ChiangmaiAges 20–70 - NCT06905262Recruiting
Finding cancer targets for liver cancer immunotherapy
This trial aims to discover new immune system targets on liver cancer cells and other tumors to develop better immunotherapies. Researchers will analyze tumor samples to find these targets, which could lead to more effective treatments.
NaplesAges 18–100 - NCT06904014RecruitingPhase 2
Testing a new drug combo before surgery for liver cancer
This trial tests if combining three therapies (sintilimab, lenvatinib, and HAIC) before surgery can help shrink liver tumors that are on the borderline of being removable. It's for people whose cancer has spread into nearby blood vessels but not to other organs.
Jinan, ShandongAges 18–70 - NCT04025541Recruiting
Blood tests to study tumor markers
This trial looks at blood samples to measure substances that may reflect cancer (tumor markers). It may help doctors understand cancer better and improve future monitoring, as long as you can safely and regularly take part.
MontpellierAges 18 years+ - NCT07241663Recruiting
Surgery for locally advanced pancreatic cancer
This trial is testing whether surgery can help people with a certain type of pancreatic cancer that is locally advanced but not yet spread. You may join if your cancer has shrunk or stayed stable after at least 4 months of chemotherapy and your medical team thinks surgery is possible.
