About FIERCE-22
FIERCE-22 is a Phase 1b/2 trial evaluating vofatamab, a FGFR3-targeted antibody, in combination with pembrolizumab, an immune checkpoint inhibitor, to determine safety, tolerability and preliminary efficacy in the treatment of patients with locally advanced or metastatic bladder cancer who have progressed following platinum-based chemotherapy and who have not received prior immune checkpoint inhibitor therapy.

About Vofatamab
Vofatamab (formerly B-701) is an antibody specifically targeted against the fibroblast growth factor receptor 3 (FGFR3), a known driver of bladder and potentially other FGFR-driven cancers. Vofatamab is the most advanced targeted antibody specific for FGFR3 known by Rainier Therapeutics to be in clinical development. Vofatamab is currently being evaluated in two clinical trials: FIERCE-22 and FIERCE-21.
