简要总结
The purpose of this study is to test the safety of avelumab and Bacille Calmette-Guerin (BCG) and see what effects (good and bad) that this combination treatment has on subjects with recurrent bladder cancer.
详细描述
There will be exams, tests and procedures to see if the patient is eligible for the study. Some are part of regular cancer care and others are part of the study. Subjects will also need to complete a research questionnaire at certain points in the study.
Subjects will receive treatment of avelumab and intravesical BCG until unacceptable toxicity or tumor progression.
Study participation is up to three years.

- •Treatment with any approved anti-cancer therapy, including chemotherapy (systemic or intravesical), radiation therapy, or hormonal therapy within 3 weeks prior to the first dose of study treatment
- •Treatment with any other investigational agent or participation in another clinical study with therapeutic intent within 4 weeks prior to the first dose of study treatment
