19-BI-1808-01, a phase 1/2a clinical trial of BI-1808, a tumor necrosis factor receptor 2 (TNFR2) blocker/depleter with or without pembrolizumab.
2641Background: BI-1808 is an IgG1 mAb that target TNFR2 by blocking interaction of TNFR2 with ligand TNF-α, confers FcγR-dependent depletion of Treg and mediates expansion of intratumoral CD8+ T cells. Upon co-administration of murine surrogate antibodies targeting TNFR2 and anti-PD-1 to immunocompetent tumor-bearing mice with partial sensitivity to checkpoint blockade, complete cures were observ
