Immune checkpoint inhibition therapies have been used for multiple cancer research. H11-HLE is a tool molecule that allows the interrogation of the contribution of Fc in mediating immune checkpoint therapy. Half-life extended H11 (H11-HLE) induces potent anti-tumor efficacy in mouse syngeneic tumor models.

Authors gratefully acknowledge performing in vivo studies by Medicilon Preclinical Research LLC who performed the in vivo experiments.
