ClinConnect Summary
This clinical trial is looking at a new treatment approach for patients with a specific type of bladder cancer called non-muscle invasive bladder cancer (NMIBC) that is at high or very high risk of returning. The study will test a combination of two medications, Disitamab Vedotin and Tislelizumab, along with a second surgery to remove any remaining cancer cells. The goal is to see how effective and safe this treatment is for patients whose cancer shows high levels of a protein called HER2.
To participate in this trial, individuals must be between 18 and 85 years old and have been diagnosed with high or very high-risk NMIBC. They should have had a recent surgery to remove the tumor and have certain health conditions under control, including no severe organ failures. Participants will undergo several tests to ensure they are suitable for the study. Those who join will help researchers learn more about this potential treatment and will be closely monitored throughout the trial to ensure their safety.
