Authors: Meagan B Ryan / Bradley Quade / Natasha Schenk / Zhong Fang / Marshall Zingg / Steven E Cohen / Brooke M Swalm / Chun Li / Aysegul Ozen / Chaoyang Ye / Maria Stella Ritorto / Xin Huang / ...Authors: Meagan B Ryan / Bradley Quade / Natasha Schenk / Zhong Fang / Marshall Zingg / Steven E Cohen / Brooke M Swalm / Chun Li / Aysegul Ozen / Chaoyang Ye / Maria Stella Ritorto / Xin Huang / Arvin C Dar / Yongxin Han / Klaus P Hoeflich / Michael Hale / Margit Hagel / Abstract: Alterations in the RAS-MAPK signaling cascade are common across multiple solid tumor types and is a driver for many cancers. NST-628 is a potent pan-RAF-MEK molecular glue that prevents ...Alterations in the RAS-MAPK signaling cascade are common across multiple solid tumor types and is a driver for many cancers. NST-628 is a potent pan-RAF-MEK molecular glue that prevents phosphorylation and activation of MEK by RAF, overcoming the limitations of traditional RAS-MAPK inhibitors and leading to deep durable inhibition of the pathway. Cellular, biochemical, and structural analysis of RAF-MEK complexes show that NST-628 engages all isoforms of RAFand prevents the formation of BRAF-CRAF heterodimers, a differentiated mechanism from all current RAF inhibitors. With a potent and durable inhibition of the RAF-MEK signaling complex as well as high intrinsic permeability into the brain, NST-628 demonstrates broad efficacy in cellular and patient-derived tumor models harboring diverse MAPK pathway alterations, including orthotopic intracranial models. Given its functional and pharmacokinetic mechanisms that are differentiated from previous therapies , NST-628 is positioned to make an impact clinically in an areas of unmet patient need. | |||||||||
