BL-M05D1 for advanced stomach cancer after first treatment
This study tests a new antibody drug (BL-M05D1) for advanced stomach or lower esophagus cancer that did not respond to first-line chemotherapy. The drug targets a protein called claudin 18.2 found on some cancer cells and may help slow or shrink the cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT06756009Recruiting
Eye scans to check liver disease and transplant outlook
This study uses advanced eye scans to see if your eyes can give clues about your chronic liver disease and how well you might do after a liver transplant. If you have advanced liver disease or cirrhosis, and are maybe waiting for a transplant, you may join.
Guangzhou, GuangdongAges 18 years+ - NCT06474468RecruitingPhase 1/Phase 2
Study of a new drug combo for advanced esophageal cancer
This trial tests a combination of two investigational drugs for people with advanced or metastatic esophageal squamous cell carcinoma. The goal is to see if the combination can shrink tumors or slow cancer growth.
Jinan, ShandongAges 18–70 - NCT06339801Recruiting

Outpatient care after emergency appendix removal surgery
This trial tests whether patients with a specific type of appendix infection (gangrenous appendicitis) can safely recover at home instead of staying in the hospital after surgery. The goal is to see if home-based care with close follow-up visits works as well as traditional hospital stays.
Seville, SevillaAges 14 years+ - NCT07520500Recruiting
Comparing two surgical techniques for high anal fistula
This trial compares two surgical methods (IFOC and LIFT) for treating high anal fistulas—abnormal tunnels that form near the anus. The goal is to determine which approach works better and has fewer side effects.
