Roche Bladder Cancer BLA Accepted for Review
FDA has accepted for priority review a Roche Group BLA for MPDL3280A (atezolizumab) for treating people with locally advanced or metastatic urothelial carcinoma who had disease progression during or after platinum-based chemotherapy in the metastatic setting. The company is also seeking approval for use in those whose disease worsened within 12 months after receiving chemotherapy before surgery (neoadjuvant) or after surgery (adjuvant). Urothelial carcinoma accounts for 90% of all bladder cancers and can also be found in the renal pelvis, ureter and urethra.
“Atezolizumab was granted a priority review designation based on results of the IMvigor 210 study, which showed the medicine shrank tumors in a type of advanced bladder cancer, and the majority responding to treatment continued to respond after nearly a year of follow up,” the company says. The user fee review target date is 9/12.
Atezolizumab is an investigational monoclonal antibody designed to bind with a protein called programmed death ligand-1 (PD-L1). according to the company. It is designed to directly bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with PD-1 and B7.1 receptors. By inhibiting PD-L1, it may enable the activation of T cells, Roche says.
