Study of Atezolizumab with BCG Treatment for Patients with High-Risk Non-Muscle Invasive Bladder Cancer Who Have Not Previously Received BCG

3 1 1 1

What is this study about?

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.

1 Initial evaluation

Your participation begins after completing the surgical procedure and receiving confirmation of high-risk non-muscle invasive bladder cancer

Medical imaging (CT scan or MRI) must be performed within 90 days before starting treatment to confirm the absence of cancer spread

Basic health tests including blood pressure and laboratory tests will be conducted within 7 days before starting treatment

2 Treatment assignment

You will be randomly assigned to one of two treatment groups:

Group 1: BCG treatment alone (bladder instillation)

Group 2: BCG treatment plus atezolizumab (bladder instillation plus intravenous medication)

3 Treatment period – Year 1

Treatment will continue for one year

You will receive BCG instillations directly into your bladder

If assigned to group 2, you will also receive Tecentriq (atezolizumab) 1,200 mg through intravenous infusion

4 Monitoring and evaluation

Regular check-ups will occur every 12 weeks during the first two years

Health assessments will include cystoscopy (bladder examination) and urine tests

Quality of life questionnaires will be completed every 12 weeks

Side effects will be monitored and recorded throughout the study

5 Long-term follow-up

After the first two years, check-ups will occur every 24 weeks for years 3-5

Continued monitoring of your health status and cancer-related events

The total study duration is expected to continue until October 2028

Trial locations

Investigated drugs:

Atezolizumab

Atezolizumab is a type of immunotherapy medication that helps your immune system fight cancer cells. It works by blocking a protein that cancer cells use to hide from your immune system, allowing your body’s natural defenses to better recognize and attack the cancer.

BCG (Bacillus Calmette-Guerin) is a treatment that’s placed directly into the bladder through a catheter. It’s made from weakened bacteria that stimulate your immune system to fight cancer cells in the bladder. This is a standard treatment for high-risk bladder cancer that hasn’t invaded the muscle wall.

Investigated diseases:

Bladder cancer

Non-muscle invasive bladder cancer – A type of bladder cancer that affects the inner lining of the bladder without invading the muscle layer. The cancer starts in the cells that line the bladder and can form small growths called papillary tumors or flat areas known as carcinoma in situ (CIS). The disease can occur in different stages, from very early superficial tumors to those that have grown deeper into the bladder lining. When classified as high-risk, it means the cancer has certain characteristics that make it more likely to return after initial treatment. The condition is typically discovered after patients experience symptoms such as blood in urine or changes in urination patterns.
