In Vivo CA-4948 is a selective and potent IRAK4 kinase inhibitor with in vivo activity in a TLR4-induced cytokine release model. CA-4948 exhibits favorable drug metabolism and pharmacokinetic (DMPK) properties, oral bioavailability, and is well tolerated in mice. Moreover, CA-4948 exhibits dose-dependent efficacy in activated B-cell (ABC)-DLBCL MYD88-L265P xenograft tumor models using cell lines OCI-LY3 and OCI-LY10. CA-4948 exhibits the greatest efficacy in four of the five ABC-DLBCL PDX models tested as compared to GBC-DLBCL and ABC/GCB DLBCL patient-derived DLBCL tumor xenograft (PDX) models. Furthermore, CA-4948 is efficacious in ABC-DLBCL PDX tumors containing activating mutations in both TLR/IL-1R and BCR signaling pathways (MYD88 and CD79B double mutants)[2].
