Researchers from Mbrace Therapeutics Inc. presented the discovery and preclinical evaluation of MBRC-101, a novel antibody-drug conjugate (ADC) targeting the membrane-associated tyrosine kinase receptor EphA5, being developed for the treatment of cancer.
Retinoic acid receptor-γ (RARγ) agonism is a key factor in CD8 T-cell-mediated immunity to infectious pathogens. The lack of studies on the effects of RARγ agonists on in vivo tumor growth of triple-negative (TNBC) or HER2+ breast cancers make it necessary to investigate whether RARγ could play a critical role in T-cell-mediated immunity in these breast cancers, using novel RARγ nuclear agonists.
PI3Kα H1047R accounts for one-third of all PI3Kα mutations and is associated with treatment resistance to targeted therapies in breast cancer treatment. In addition, treatment with selective PI3Kα inhibitors often results in significant adverse events such as hyperglycemia due to on-target toxicity.
