2020-03-12 · CD137 (4-1BB) is a member of the TNFR superfamily that represents a promising target for cancer immunotherapy. Recent insights into the function of TNFR agonist antibodies implicate epitope, affinity, and IgG subclass as critical features, and these observations help explain the limited activity and toxicity seen with clinically tested CD137 agonists. Tumor target-dependent CD137 agonism using a novel chemical approach (TICAs) afforded elimination of tumors with only intermittent dosing suggesting potential for a wide therapeutic index in humans. This work unlocks a new path to effective cancer immunotherapy via agonism of TNF superfamily recepto … 2020-03-12 · Cell surface glycoprotein CD137 (also known as 4-1BB and TNFRSF9) is a member of the TNFRSF that is expressed on activated T cells, Tregs, NK cells, monocytes, DCs, and tumor endothelial cells (2). 2016-01-01 · CD137 signaling enhanced the production of proinflammatory cytokines and cytotoxic molecules in tumor-specific CD4 (+) T cells.

MCLA-145 is a human CD137xPD-L1 bispecific common light chain antibody (bAb), identified through functional screening of agonist and ICI bAb combinations. Further, MCLA-145 can overcome Treg and macrophage suppression to potently activate T cells in these immune suppressive conditions. CD137 agonist antibody in combination with GVAX and PD-1 antagonist antibody improved survival in a murine model of metastatic PDAC The primary goal of our study was to investigate new strategies to enhance the effects of pancreatic GVAX vaccine and anti-PD-1 antibody (αPD-1) combination therapy. Background: CD137 is a member of the TNFR family and functions as a costimulatory molecule. In preclinical studies BMS- 663513, a fully human anti-CD137 agonist monoclonal antibody provided costimulation to CD8+ and CD4+ T-cells, leading to enhanced IFNγ production, cytolytic activity, and increased survival.

CD137 Agonist Antibody Pipeline Insight, 2021 report by DelveInsight offers comprehensive insights of the pipeline (under development) therapeutics scenario and growth prospects across CD137 Agonist Antibody development. Utomilumab (PF-05082566) is a fully-human IgG2 agonist mAb that selectively binds human 4-1BB/CD137, resulting in NF-κB activation and downstream cytokine production in cell lines and primary lymphocytes (17). Epitope and Fc-Mediated Cross-linking, but Not High Affinity, Are Critical for Antitumor Activity of CD137 Agonist Antibody with Reduced Liver Toxicity Epitope and Fc-Mediated Cross-linking, but Not High Affinity, Are Critical for Antitumor Activity of CD137 Agonist Antibody with Reduced Liver Toxicity Engagement of CD137 on T cells by natural ligand or agonist monoclonal antibody (mAb) enhances T-cell proliferation and provides protection to CD8 T cells from activation-induced cell death through nuclear factor κB–mediated activation and up-regulation of the antiapoptotic Bcl-2 family members Bcl-xL and Bfl-1. 5 Stimulation of CD137 could also lead to activation of dendritic cells, 6 NK cells, 7 and macrophages 8, 9 in vitro.
