Study of DV with cadonilimab for HER2-positive stomach cancer
This trial tests a combination of two drugs (DV and cadonilimab) for people with HER2-positive stomach or gastroesophageal junction cancer that has grown after first treatment. It aims to see if this combo can help when standard options have stopped working.
Beijing, Beijing MunicipalityAges 18–75 - NCT06222255Recruiting
Transanal irrigation for sleep issues after rectal cancer surgery
This trial tests if a special irrigation technique can improve sleep problems caused by low anterior resection syndrome (LARS) after rectal cancer surgery. It may help people who have ongoing bowel symptoms that disrupt sleep.
Seoul, Jongro-guAges 19–80 - NCT06222645Recruiting
Comparing two dyes in gastrointestinal surgery
