Atezolizumab Given in Combination With a Personalized Vaccine in Patients With Urothelial Cancer

Brief description of study

The purpose of this study is to determine the good and bad effects of atezolizumab given in combination with a personalized cancer vaccine in patients with urothelial cancer either after surgery to remove organ where the tumor arose (for example, removal of the bladder) or for urothelial cancer that has spread to other organs.

Detailed Study Description

This is a single arm, proof-of-concept study. Fifteen subjects with urothelial cancer interested in participation will sign a "tissue acquisition and vaccine preparation consent" after which tumor tissue will be obtained from either a surgical resection specimen or biopsy. Subjects are scheduled to undergo cystectomy or nephroureterectomy for invasive urothelial cancer may consent prior to, or within 6 weeks after, surgery. The tumor specimen will be submitted for genomic sequencing followed by neoantigen identification utilizing a computational pipeline. Peptides corresponding to these neoantigens will be prepared for the personalized vaccine product. Subjects eligible for the treatment phase of the protocol (i.e., after surgery in adjuvant patients and chemotherapy in metastatic patients) will receive atezolizumab every 3 weeks plus up to ten doses of PGV001 vaccination plus Poly-ICLC. The primary objectives will be to determine the feasibility and safety of administration of a personalized neoantigen-based vaccine (PGV001) plus atezolizumab in subjects with locally advanced or metastatic urothelial cancer.
