Kymera’s KT-413 is a CRBN-based dual-mechanism degrader that degrades both IRAK4 and the transcription factors IKZF1/3, acting as an IMiD, with promising clinical activity for the treatment of ABC-like subtype of DLBCL. This fascinating case study demonstrates how a dual-mechanism degrader of IKZF1/3 and IRAK4 can be designed to maximize NF-κB inhibition while simultaneously upregulating the Type I interferon response. This approach restores the apoptotic response and enables oncogene-mediated cell death, resulting in a robust antiproliferative and pro-apoptotic effect in MYD88 mutants.
