Changchun Genescience Pharmaceuticals Co. Ltd. has synthesized new molecular glue degraders comprising E3 ubiquitin-protein ligase-binding agents acting as proto-oncogene Vav (VAV1) degradation inducers. They are described as potentially useful for the treatment of ulcerative colitis, Crohn’s disease, rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosus and myasthenia gravis.
Chronic activation or upregulation of interleukin-1 receptor-associated kinase 4 (IRAK4) has been linked to several diseases, including systemic lupus erythematosus, rheumatoid arthritis, atopic dermatitis, Alzheimer’s disease and atherosclerosis. Researchers from the Ocean University of China aimed to address the limitations of traditional small-molecule inhibitors by designing novel proteolysis targeting chimeras (PROTACs) for IRAK4 degradation.
The EMA is recommending withdrawing Amgen Inc.’s complement inhibitor Tavneos (avacopan) from the market in Europe, saying data provided at the time it assessed the MAA “were found to be incorrect and misleading and could no longer be relied upon for demonstrating Tavneos’ effectiveness.”
