Immunopharmacology Comments
Spartalizumab (PDR001) is an anti-PD-1 monoclonal antibody (immune checkpoint inhibitor) that is in clinical devlopment as an immuno-oncology therapeutic. It binds strongly to purified PD-1 by Biacore analysis and inhibits binding of PD-L1 and PD-L2 to PD-1 in whole cell assays [1]. Functionally spartalizumab modulates PD-1-dependent activities and restores effector T cell functions such as proliferation, IFNγ secretion and cytolytic capacity. In addition, it favourably alters the activity of other immune cells such as regulatory T cells and NK cells, which combined with increased effector T cell activity, brings about an enhanced immune response against cancer cells.
