Immunopharmacology Comments
IRAK4 is essential for most innate immune responses to bacteria and viruses, and IRAK4 deficiency (caused by mutations) has been shown to result in recurrent invasive pneumococcal disease [24].

The mechanistic explanation for IRAK4's importance is revealed in this proteins central role in TLR/IL-1R superfamily signalling (this superfamily of proteins includes the Toll-like receptors and receptors for pro-inflammatory cytokines IL-1 and IL-18, which all share a Toll/IL-1R homology (TIR) domain in their intracellular region). Signalling via TIR-containing receptors depends on the formation of a multi-protein complex termed the Myddosome, so-named as hierarchical complex formation begins with recruitment of the TIR-containing adaptor protein MyD88 [26]. MyD88 recruits IRAK4 and this complex further recruits the IRAK4 substrates IRAK2 or the related IRAK1 [23]. Formation of the Myddosome brings the IRAK kinase domains in to proximity, facilitating phosphorylation and activation and ultimately activation of transcription factors NF-κB, AP-1 and IRFs (e.g. IRF5 [12]) to stimulate anti-pathogen responses and inflammation [15,25].

The development of clinically useful IRAK4 inhibitors is underway, with investigational indications including autoimmune and inflammatory diseases, and cancer. Lead compounds in development pipelines include BMS-986126, ND-346 and CA-4948 which are being considered as therapuetics for SLE, lymphomas and other malignancies [14,19]. However, any preclinical assessment should address the relevance of IRAK4 splice variants which may influence inhibitor selectivity and/or expression profile, as well as considering the side effects of inhibiting such a crucial enzyme. Other areas for potential development include: Cardiac inflammation and damage (TLR4 activation in response to ischaemia), CNS and neuropathic pain (TLR4 receptors are upregulated in neuropathic pain and in neuroinflammatory states, particularly on microglia) [9], asthma [11], multiple sclerosis and other Th17-driven immunological conditions [29].

As an alternative to IRAK4 inhibition, Kymera Therapeutics have developed an orally delivered IRAK4 selective ubiquitin-mediated protein degrader molecule (KT-474) that they are initially progressing for atopic dermatitis and hidradenitis suppurativa (see NCT04772885). KT-474 is designed to block IRAK4-mediated inflammatory signalling in two independent ways; 1) inhibiting IRAK4 kinase activity and, 2) disrupting its scaffold function in myddosome assembly. KT-474 offers clinical potential beyond dermatologic indications, such as in rheumatic, respiratory and gastrointestinal inflammatory diseases. KT-474 is the first molecular degrader class drug to enter clinical development for non-oncology indications.
