LIBTAYO helps to restore the antitumor T-cell response1

LIBTAYO is a human, hinge-stabilized IgG4, high-affinity PD-1 monoclonal antibody developed using VelocImmune® technology. As a result of LIBTAYO's inhibition of the PD-1—PD-L1/PD-L2 signaling pathway, T-cell receptor signaling can be reactivated, restoring antitumor activity.1,2
