Cd137 agonist

CD137 (TNFRSF9, 4-1BB) agonist antibodies (mAb) have demonstrated potent antitumor activity with memory response while causing hepatotoxicity in mouse models. In clinical trials, the degrees of liver toxicity of anti-CD137 vary from grade 4 transaminitis (urelumab) to nonexistent (utomilumab). 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.

Rationale for CD137 agonists in cancer Translating CD137 co-stimulation to the clinic CD137 (TNFRSF9, 4-1BB) is a member of the tumor necrosis factor receptor superfamily that functions as a potent co-stimulator of adaptive and innate immune cells1 (Figure 1). The antitumor activity from targeting the CD137 mm2 the mice were dosed i.

More interestingly, treatment with CD137 agonistic an agonistic anti-CD137 antibody induces the regres- LEC culture and CD137 agonist treatment. Primary

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).

The CD137 receptor plays a key role in mediating immune response by promoting T cell proliferation, survival, and memory. Effective agonism of CD137 has the potential to reinvigorate potent antitumor immunity either alone or in combination with other immune-checkpoint therapies.

Conditions mediated by IgE include asthma, atopic dermatitis, and allergy. CD137 agonists are also useful for treating conditions characterized by delayed eosinophil apoptosis, including nasal polyps and hypereosinophilic syndrome. Lyvgen’s most advanced programs based on xLinkAb™ platform include LVGN6051, a CD137(4-1BB) agonist, and LVGN7409, a CD40 agonist. Contacts Luyan Liu Luyan.Liu@lyvgen.com Microenvironment and Immunology Agonist Anti-CD137 mAb Act on Tumor Endothelial Cells to Enhance Recruitment of Activated T Lymphocytes Asís Palazon 1, Alvaro Teijeira 1,Ivan Martínez-Forero , Sandra Hervas-Stubbs , Carmen Roncal1, Creation of STA551, an anti-CD137 agonist antibody that binds to CD137 in an adenosine triphosphate (ATP)-dependent manner and exerts agonistic activity, which is known to be present at high concentrations in solid tumor tissues. STA551 binds to CD137 and activates T cells in the presence of ATP, but not in the absence of ATP (in vitro) Immunostimulatory agonists such as anti-CD137 and interleukin (IL)-2 have elicited potent antitumor immune responses in preclinical studies, but their clinical use is limited by inflammatory toxicities that result upon systemic administration. The EphA2/CD137 1:2 construct exhibited a similar potency and maximal activity in the reporter cell assay as an anti-CD137 agonist antibody (online supplemental figure S4E).

ADG106 is a fully human ligand-blocking, agonistic anti-CD137 IgG4 mAb.

Agonist anti-CD137 mAb act on tumor endothelial cells to enhance recruitment of activated T lymphocytes. CD137-medierad signalering är också känd för att skydda T-celler, och i bioteknikföretaget Jounce Therapeutics utvecklar en ICOS-agonist.

These data support the hypothesis that 4-1BB/CD137 agonist antibodies can increase innate and adaptive immune responses arising after treatment with ADCC-competent antibodies. 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 ). Background: CD137 is a member of the TNFR family and functions as a costimulatory molecule.
