Durvalumab and Vicineum in Subjects With High-Grade Non-Muscle-Invasive Bladder Cancer Previously Treated With Bacillus Calmette-Guerin (BCG)

• Status: Recruiting
• Trial end date: 2023-12-30

Summary

Background:

Non-muscle-invasive bladder cancer is in the early stages. But it usually comes back after treatment. The drugs Vicineum and Durvalumab may help the immune system find and destroy cancer cells.

Objective:

To test if the drugs Durvalumab and Vicineum together are safe and effective to treat people with bladder cancer that has not spread to the muscle in the bladder.

Eligibility:

People ages 18 and older who have bladder cancer that has not spread to the muscle in the bladder and was treated unsuccessfully with Bacillus Calmette-Guerin

Design:

Participants will be screened with:

Medical history

Physical exam

Blood and urine tests

Tumor sample from previous surgery. If one is not available, they will have a biopsy: A small piece of tumor is removed.

Cystoscopy to examine the inside of the bladder. This may include a biopsy or removing tumors.

CT or MRI: They lie in a machine that takes pictures of the body.

Electrocardiogram to test heart function

Participants will receive Durvalumab and Vicineum in 2 phases:

First phase: Durvalumab every 4 weeks and Vicineum once a week for 3 months

Second phase: Durvalumab every 4 weeks and Vicineum once every other week

Participants will have tumor samples taken every 3 months. They will have blood and urine tests throughout the study.

Participants will continue treatment for up to 2 years.

Participants will have a visit about 30 days after their last treatment. This includes blood and urine tests. It may include a cytoscopy or additional biopsies.
