Comment: CA-4948 is an orally available, reversible inhibitor of interleukin 1 receptor associated kinase 4 (IRAK4) . It downmodulates the IRAK4 kinase activity that is required for toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) signaling in a variety of myeloid and lymphoid cell types, notably in cancer cells (e.g. diffuse large B-cell lymphoma cells) in which the MYD88 adaptor protein carries an activating mutation (MYD88L265P) [2]. In such mutant cells NF-κB signaling is constitutively active and this is indicative of a poorer prognosis. Hence, IRAK4 inhibitors such as CA-4948 are expected to provide clinical benefit in MYD88 mutation +ve hematological cancers.
Although not formally disclosed in a peer-reviewed publication, the structure presented here is that claimed as Example 1 in Aurigene Discovery Technologies' IRAK4 inhibitor patent WO2015104688A1 [3]. Data presented in scientific meeting abstract form indicates that CA-4948 demonstrates preclinical antitumour activity in in vitro and in vivo models [1].
