About Cervical Cancer
Nearly 14,000 women are expected to be diagnosed with invasive cervical cancer in the United States this year and more than 4,000 are expected to die.¹ Cervical cancer remains one of the leading causes of cancer death in women globally, annually killing more than 300,000 women worldwide.² Despite advances in routine medical examinations and HPV vaccines, cervical cancer remains prevalent. When left undetected, recurrent or metastatic cervical cancer often develops, for which there are limited treatment options and a low chance of survival. Current therapies for recurrent or metastatic cervical cancer are limited to a small subset of patients with limited benefit.

About balstilimab
Balstilimab is a novel, fully human monoclonal immunoglobulin G4 (IgG4) designed to block PD-1 (programmed cell death protein 1) from interacting with its ligands PD-L1 and PD-L2. PD-1 is a negative regulator of immune activation that is considered a foundational target within the immuno-oncology market. Balstilimab is currently in clinical trials as monotherapy and in combination with Agenus’ anti-CTLA-4, zalifrelimab, in an ongoing Phase 2 study for recurrent/metastatic cervical cancer.
