Immunopharmacology Ligand
Compound class: Antibody
Comment: Rezorstobart (IMT-009; Immunitas Therapeutics) is an anti-CD161 (KLRB1) monoclonal antibody. It is designed to prevent receptor interaction with its ligand C-type lectin domain family 2 member D, to disinhibit natural killer cells and promote a T cell-mediated anti-tumour response. Peptide sequences for the heavy and light chains of rezorstobart are claimed as consensus sequences of Ab9 in Immunitas Therapeutics' patent US12215159 [5].
