Vopratelimab (JTX-2011) is a humanized immunoglobulin G1-kappa agonist monoclonal antibody that pecifically binds to the Inducible CO-Stimulator of T cells (ICOS). Vopratelimab retains species cross-reactivity with affinities of 0.93 nM to hICOS, 0.46 nM to cynomolgus ICOS, 3.7 nM to rat ICOS, and 0.64 nM to mICOS. Vopratelimab has antitumor immune response[1].
Vopratelimab (JTX-2011; 0.001-10 μg/mL; 3 d; CD4 T cells) has the activity of activating primary human T cells, driving IFNγ, IL-17a, IL-10, IL-9, GM-CSF, TNFα, and IL-21 secretion[1].
Vopratelimab (JTX-2011; 0.25-0.3 mg/kg; i.p.; twice a week, for 2 weeks) promotes tumor regression in the Sa1/N murine syngeneic tumor model[1].
