Immunotherapy builds a population of immune cells over time that specifically target cancer cells1-4

The activated immune system adapts as cancer mutates, enabling it to recognize new tumor antigens2-3,5-6

The immune system has memory and remains primed to stimulate a tumor-specific response1,7

Patients may respond differently to immunotherapy than to traditional cancer agents.

  • Immunotherapy targets the tumor over time, so although response may occur more slowly than with traditional cytotoxic therapies, the immune effect is potentially adaptable and durable2-4

  • RECIST criteria were designed to assess response to traditional cytotoxic agents so they are not as relevant for immunotherapy, which works differently2-4
