Abstract

Meeting abstracts Antibody-interferon-alpha (IFNα) fusion proteins represent a cancer therapeutic with properties of an antibody-drug conjugate and an immunotherapy, having both direct anti-tumor and immune-activating effects. We report the anti-tumor activity of IGN004, an antibody-IFNα fusion

Highlights

  • Antibody-interferon-alpha (IFNa) fusion proteins represent a cancer therapeutic with properties of an antibodydrug conjugate and an immunotherapy, having both direct anti-tumor and immune-activating effects

  • IGN004 unfused antibody bound to the majority of tumor cell lines and primary tumors assessed

  • In an in vitro T cell killing assay using TALL-104 cells as effectors and A549 nonsmall cell lung cancer (NSCLC) cells as targets, the addition of IGN004 led to enhanced effector cell killing of tumor (69.2% killing without IGN004 vs. 100% killing with IGN004; p = 0.001)

Summary

Background

Antibody-interferon-alpha (IFNa) fusion proteins represent a cancer therapeutic with properties of an antibodydrug conjugate and an immunotherapy, having both direct anti-tumor and immune-activating effects. We report the anti-tumor activity of IGN004, an antibody-IFNa fusion protein against a novel tumor-associated antigen expressed by many solid and liquid tumors
