This study focuses on patients with high-risk non-muscle invasive bladder cancer who have undergone transurethral resection of the bladder. The research evaluates a treatment combining two medications: atezolizumab (given through intravenous infusion) and BCG (Bacillus Calmette-Guerin), which is administered directly into the bladder. The purpose is to determine if using both treatments together works better than using BCG alone.
The treatment plan involves receiving Tecentriq (atezolizumab) as an intravenous solution, with each dose containing 1,200 milligrams of medication. Patients will receive treatment for up to 12 months. During this time, some patients will receive both atezolizumab and BCG bladder treatments, while others will receive only BCG treatments.
Throughout the study, patients will have regular check-ups to monitor their health. These visits include medical examinations and quality of life assessments. The doctors will track how long patients remain free from cancer events and watch for any signs that the disease has returned or gotten worse. Blood and urine samples will be collected to study how the treatment is working.
