Approved drug
pucolentimab is an approved drug
Compound class: Antibody
Comment: Pucolentimab (formerly HX008) is an anti-PD-1 immune checkpoint inhibitor monoclonal antibody [2]. It blocks interactions between PD-1 and its ligands PD-L1 and PD-L2, and this reactivates a T cell-mediated antitumour response. Pucolentimab has negligible binding to Fc-gamma receptors (FcγRIIIa) or or C1q and therefore exhibits minimal ADCC and CDC activity [2].
