Abstract

Immunotherapy has significantly improved treatment outcomes for cancer patients within the past decade, with breakthrough results using immune checkpoint inhibitors (ICIs), most notably those targeting the PD-1/PD-L1 inhibitory axis. Nevertheless, many patients and tumor types do not respond to current ICIs, and next-generation drugs are urgently needed. Dual Signaling Protein 216 (DSP216) is a new ligand-based immunotherapeutic-a dual HLA-G and CD47 ICI. DSP216 was designed to exclusively bind to cells co-expressing the immune checkpoints CD47 and HLA-G, thereby mitigating ICI activity towards normal cells expressing only CD47 or HLA-G and associated side effects. Computational chemistry was used to optimize DSP216 affinity to HLA-G with the aim to achieve the desired binding mode and DSP216 binding to CD47
