Addition of interleukin-2 overcomes resistance to neoadjuvant CTLA4 and PD1 blockade in ex vivo patient tumors.

Abstract

T cells early after neoadjuvant triple immunotherapy. Our results suggest that the addition of IL-2 can overcome resistance to neoadjuvant anti-CTLA4 + anti-PD1, providing the rationale for testing this combination as a neoadjuvant therapy in patients with early-stage cancer.
