CAMBRIDGE, Mass.,?July 9, 2020?/PRNewswire/ --?Kymera Therapeutics Inc. today announced the company has entered into a multi-program strategic collaboration with Sanofi (NASDAQ:?SNY) 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?in cash upfront and may receive more than?$2 billion?in potential development, regulatory and sales milestones, as well as significant royalty payments. Kymera retains the option to participate in US development and commercialization for both programs. This includes the ability to participate equally in the costs, profits and losses after opt-in, and to co-promote partnered products in the US. "This is an important collaboration for both companies and for the field of targeted protein degradation," said?Nello Mainolfi, Ph.D., co-founder, President and CEO of Kymera Therapeutics. "Kymera is becoming a fully integrated biotechnology company advancing a pipeline of novel therapies with the potential to transform treatment paradigms. We are excited to partner with Sanofi, an organization with world-class? drug development and commercialization capabilities, to ensure maximal patient impact from two of our programs across multiple disease indications, while enabling Kymera to invest in key strategic areas to realize the broad potential of protein degrader therapies." Under terms of the collaboration, Sanofi will make an upfront payment of?$150 million?in cash to Kymera for global rights to develop its small molecule IRAK4 protein degraders in inflammation and immunology indications, and a second earlier stage undisclosed program. 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 clinical trials; Sanofi will assume clinical development and commercialization responsibilities thereafter. Sanofi will lead all clinical development activities for the second program. Kymera will have the option to participate in the development of both programs in the US during clinical development. 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. Data presented at the most recent annual meetings of the American College of Rheumatology and the European Hidradenitis Suppurativa Foundation showed potent anti-inflammatory activity in both?in vitro?and?in vivo?preclinical models. "Targeted protein degradation is an exciting modality. Kymera has developed an incredible drug discovery engine producing protein degraders with compelling and differentiated pharmacology against targets that, to date, have not been optimally addressed with other therapeutic modalities," said?John Reed, Global Head of Research & Development at Sanofi. "We are excited to partner with the Kymera team to advance a new generation of first-in-class therapies with the potential to eliminate underlying drivers of disease." Aquilo Partners, L.P. acted as financial advisor to Kymera on this transaction. About Kymera Therapeutics
