Kymera Therapeutics Inc. has entered into a multi-program strategic collaboration with Sanofi to develop and commercialize first-in-class protein degrader therapies targeting IRAK4 in patients with immune-inflammatory diseases. The companies will also partner on a second earlier stage program. Kymera will receive $150 million upfront and may receive more than $2 billion in potential development, regulatory, sales milestones, as well as royalty payments. Kymera retains the option to participate in U.S. development and commercialization for both programs.
IRAK4 is believed to play a key role in multiple immune-inflammatory diseases, including hidradenitis suppurativa, atopic dermatitis and rheumatoid arthritis. Kymera will advance the IRAK4 program through Phase 1 trials and Sanofi will assume clinical development and commercialization responsibilities thereafter. Sanofi will lead all clinical development activities for the second program. Kymera will retain global rights to its IRAK4 program in oncology indications.
IRAK4 is a key protein involved in inflammation mediated by the activation of toll-like receptors (TLRs) and IL-1 receptors (IL-1Rs). While TLR and IL-1R signaling via IRAK4 is involved in the normal immune response, aberrant activation of these pathways is the underlying cause of multiple immune-inflammatory conditions. In pre-clinical studies, Kymera has shown oral daily administration of an IRAK4 degrader can lead to complete knockdown of IRAK4 in skin and immune cells in higher species and is well tolerated.
