Can a Supplement Help with Nutrient Gaps for GLP-1 Users?
This study tests whether a daily supplement can help fill nutrient gaps and improve gut health for people who are already taking GLP-1 weight-loss medications (like Ozempic or Wegovy). Participants must be on a stable dose for at least 8 weeks and be generally healthy without other chronic conditions.

This trial studies a combination of trastuzumab (an antibody), gemcitabine and cisplatin (chemo), plus nivolumab (immunotherapy) as the first treatment for advanced HER2-positive biliary tract cancer. It may help shrink tumors and improve outcomes by targeting HER2 and boosting the immune system.
SeoulAges 19 years+ - NCT06806579Recruiting
Immunotherapy for advanced liver cancer
