About Rainier Therapeutics

Rainier Therapeutics, Inc. is a privately-held, clinical stage
biotechnology company developing a targeted biologic for the potential
treatment of metastatic bladder cancer. The company’s antibody,
vofatamab (formerly B-701) is focused specifically on the fibroblast
growth factor receptor 3 (FGFR3), a known driver of bladder and other
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-21
and FIERCE-22.

The Fierce 21 trial is evaluating vofatamab alone and in combination
with docetaxel versus docetaxel alone to determine safety and efficacy
in the treatment of patients with locally advanced or metastatic bladder
cancer with FGFR3 mutant/fusion who have relapsed after, or are
refractory to, at least one prior line of chemotherapy. For more on this
trial, visit www.clinicaltrials.gov

The Fierce 22 trial is evaluating vofatamab in combination with
pembrolizumab, an immune checkpoint inhibitor, to determine safety,
tolerability and 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. For more on this trial, visit www.clinicaltrials.gov

Rainier Therapeutics also plans to study vofatamab in non-muscle
invasive bladder cancer (NMIBC) – the FIERCE-23 trial.
