The checkpoint inhibitors nivolumab and atezolizumab are slated to be added to the National Comprehensive Cancer Network (NCCN) bladder cancer treatment guidelines. Both will be designated as second-line therapies after recent phase II trials revealed favorable treatment results for each drug. These findings also indicate that additional phase III trials are needed to further establish the treatment efficacy of these drugs.

Additionally, pembrolizumab may also be included in the NCCN guidelines as a treatment option for bladder cancer after a phase III trial reported better overall survival when compared to treatment with chemotherapy.
