Description: CA-4948 is a potent, and orally active interleukin-1 receptor-associated kinase 4 (IRAK4) inhibitor. CA-4948 exhibited the greatest efficacy in four of the five ABC-DLBCL PDX models tested as compared to GBC-DLBCL and ABC/GCB DLBCL PDX models. Furthermore, CA-4948 was efficacious in ABC-DLBCL PDX tumors containing activating mutations in both TLR/IL-1R and BCR signaling pathways (MYD88 and CD79B double mutants).

Additional Information

IRAK4 kinase activity is required for toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) signaling in a variety of myeloid and lymphoid cell types. Recruitment of IRAK4 to these receptors and its subsequent activation is facilitated by the MYD88 adaptor protein, which is mutated in ~22% of DLBCL cases. The MYD88 L265P activating mutation is found in ~30% of the activated B-cell (ABC) and ~6% of germinal center B-cell (GCB) subtypes of DLBCL and leads to constitutive activation of NF-κB signaling that is associated with worse prognosis. Thus, the development of small molecule inhibitors targeting IRAK4 is an attractive anticancer strategy for MYD88 mutation-containing cancers such as DLBCL.
