Genentech Inc. presented data on structure-based lead optimization of orally bioavailable hematopoietic progenitor kinase 1 (HPK1) inhibitors. HPK1 is a negative regulator of T-cell receptor signaling in human T cells and target inhibition significantly increases cytokine production, such as IFN-gamma, TNF-alpha and IL-2, and T-cell proliferation, suggesting HPK1 inhibition as an intracellular T-cell target for cancer immunotherapy.

Chimeric antigen receptor (CAR) T-cell therapy is effective in the treatment of multiple myeloma (MM), but its toxicity and complex manufacturing limit their broad use.

Yaoya Technology (Shanghai) Co. Ltd. has disclosed tyrosine-protein kinase BTK inhibitors reported to be useful for the treatment of cancer, rheumatoid arthritis, lupus erythematosus, lupus nephritis, multiple sclerosis, asthma and Sjogren's syndrome.

Researchers from Biomea Fusion Inc. presented preclinical data for the novel covalent menin inhibitor, BMF-219, after being evaluated in models of diffuse large B-cell lymphoma (DLBCL) and multiple myeloma (MM).

Applied Pharmaceutical Science Inc. has described new proto-oncogene tyrosine-protein kinase receptor Ret, (V804M mutant) and (G810R mutant) inhibitors reported to be useful for the treatment of cancer and irritable bowel syndrome.
