Interestingly, a subset of CD4 (+)Foxp3 (+) regulatory T cells was reprogrammed to eliminate immunogenic virus-induced tumor cells in response to CD137 agonist treatment. Agonist monoclonal antibodies (mAb) to the immune costimulatory molecule CD137, also known as 4-1BB, are presently in clinical trials for cancer treatment on the basis of their costimulatory effects on primed T cells and perhaps other cells of the immune system. Human peripheral blood mononuclear cells (PBMCs) were either left unstimulated (left image) or stimulated with CytoStim for 16 hours at 37 °C. Cells were then stained with CD137 antibodies as well as with CD8 antibodies. Flow cytometry was performed using the MACSQuant ® Analyzer. CD137 and/or CD137L agonists stimulate production of several inﬂammatory cytokines such as IL-6, TNF- , and MCP-1 in adipocytes and macrophages .

CD137 agonists may be employed in conjunction with other agent(s) in treating the particular conditions discussed above (i.e., a CD137 agonist and another agent or agents may be administered concurrently, consecutively, or in the form of a single composition comprising two or more agents as active ingredients). When compared with a crosslink-independent CD137 agonist mAb, the FS120 surrogate induced lower liver T-cell inﬁltration. These data support initiation of clinical development of FS120, a ﬁrst-in-class dual agonist bispeciﬁc antibody for the treatment of human cancer. Introduction OX40 and CD137 costimulatory receptors belong to the TNF CD137 agonism reporter gene assay: CD137 NF-kB luciferase reporter assay cells used following manufacturer’s instructions (Promega).

Its expression is induced on activation on a number of leucocyte types. Interestingly, for cancer immunotherapy, CD137 becomes expressed on primed T and natural killer (NK) cells, which on ligation provides powerful costimulatory signals. Perturbation of CD137 by CD137L or agonist Surprisingly, they found that this interaction reduces NK-cell activation (IFN-g and cytotoxicity).

Effective agonism of CD137 has the potential to reinvigorate potent antitumor immunity either alone or in combination with other immune-checkpoint therapies. Background CD137 (4-1BB) represents a costimulatory pathway that promotes T, NK, and dendritic cell effector functions favorable for antitumor immunity. 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.
