Botensilimab ± Balstilimab in Patients with Advanced Cutaneous Melanoma Refractory/Resistant to Anti–PD-(L)1 ± CTLA-4: A Phase 2 Trial

AGEN1571 is a novel high-affinity ILT2 antagonist antibody that promotes adaptive and innate immune responses.

Selective FcgR Co-Engagement on APCs Modulates the Activity of Therapeutic Antibodies Targeting T Cell Antigens.

FcgR Co-Engagement by Anti-TIGIT Monoclonal Antibodies Enhances T cell Functionality and Antitumor Immune Responses.

Anti-TIGIT antibodies require enhanced FcγR co-engagement for optimal T and NK cell-dependent anti-tumor immunity.
