Regulatory T cells (Tregs) are known suppressors of immunity activation in the tumor microenvironment, and a high density of Tregs is tied to a poor response to cancer immunotherapy, with CCR8+ Tregs identified as being highly suppressive. Ctm Bio Co. therefore have studied the CCR8 antagonist antibody CTM-033 in preclinical cancer models.
Investigators from Immunos Therapeutics AG aimed to develop novel anticancer therapies by using a reverse rational approach from HLA class I molecules with the aim to induce autoimmunity, and they identified HLA-B*57 as a well-known genetic factor associated with superior control of viral infections through processes not linked with peptide presentation.
Constellation Pharmaceuticals Inc. has described three-prime repair exonuclease 1 (TREX1) inhibitors reported to be useful for the treatment of cancer.
Jiangsu Simcere Pharmaceutical R&D Co. Ltd. has disclosed alkyne compounds acting as mitogen-activated protein kinase kinase kinase kinase 1 (MAP4K1; HPK1; MEKKK1) inhibitors reported to be useful for the treatment of cancer.
Activation of the cGAS-STING pathway activates the immune system through the production of type I interferons. There is knowledge that myeloid cell populations are among the most sensitive to STING agonism. Investigators at Takeda Pharmaceutical Co. Ltd. presented results on TAK-500, an immune stimulant antibody-drug conjugate (ISAC) composed of an antibody linked to a STING agonist for delivery to CCR2+ cells.
Immunocytokines (ICs) engage multiple mechanisms of action by the use of antibodies to deliver cytokine payloads to the surface of the same immune cell, known as cis-signaling. Researchers from Bright Peak Therapeutics AG have developed ICs by using a novel approach based on site-specific chemical conjugation of engineered cytokines to existing nonmodified antibodies.
Scinnohub Pharmaceutical Co. Ltd. has synthesized S-adenosylmethionine synthase isoform type-2 (Mat2A) inhibitors reported to be useful for the treatment of cancer.
Heptares Therapeutics Ltd. has presented G protein-coupled receptor GPR35 agonists reported to be useful for the treatment of acute and chronic pain, gastrointestinal and lung diseases.
AZD-4820 was evaluated in a cell viability assay performed in 30 human cancer cell lines, defining 12 different types of cancer, and testing a dose-range of multiplicity of infection (MOI); potent oncolytic activity was observed with EC50 values of <0.1 MOI in nearly all of the tested cells.
CD39 has an essential role in converting extracellular adenosine triphosphate (ATP; pro-inflammatory) into adenosine monophosphate (AMP; anti-inflammatory). Preventing the action of CD39 in the tumor microenvironment would increase levels of ATP, causing myeloid cell activation and improvement of tumor control.
