Preclinical Study of DZD8586, a Non-Covalent LYN/BTK Dual Inhibitor with Excellent BBB Penetration, for the Treatment of B-Cell Non-Hodgkin Lymphoma (B-NHL) (ASH 2023)
TMD-8-IbruR cells carrying the C481S mutation were generated by stepwise induction of increasing concentrations of Ibrutinib...In cell lines expressing C481X and pirtobrutinib resistance mutations, DZD8586 demonstrated concentration dependent anti-proliferative effects, with similar GI50s among cells carrying different BTK mutations...The Kpuu,CSF of DZD8586 in rat and monkey were 1.2 and 1.3, respectively, suggesting its excellent BBB penetration in humans. Conclusion DZD8586 is a novel non-covalent LYN/BTK dual inhibitor, which could overcome resistance mutations to the approved covalent and non-covalent BTK inhibitors, and derive clinical benefit to patients with DLBCL and CNSL by blocking both BTK-dependent and BTK-independent signaling pathways with excellent BBB penetration.
