Testing HS-20093 combinations for advanced colorectal cancer
This trial tests a new drug combination (HS-20093) for people with advanced colorectal cancer that has spread or cannot be removed by surgery. It aims to see if the combination is safe and effective.
Hangzhou, ZhejiangAges 18 years+ - NCT06827301Recruiting
Vagus nerve stimulation for swallowing problems after stroke
This trial tests a non-invasive device that stimulates a nerve in the ear to help improve swallowing after a recent stroke. It may be an option if you have moderate swallowing difficulties diagnosed within the first week after your stroke.
Roma, RMAges 18 years+ - NCT06827366Recruiting
Lifestyle study for people at high risk of colorectal cancer
This study tests a lifestyle program for people who are at high risk for colorectal cancer but have not been diagnosed. The goal is to see if healthy changes can help lower your risk over one year.
