PARIS and CAMBRIDGE, United Kingdom – January 11, 2021 – Sanofi and Kymab, a biopharmaceutical company in clinical phase that develops fully human monoclonal antibodies with a focus on immunity-mediated diseases and immuno-oncological therapies, have signed an agreement under which Sanofi will acquire Kymab for an initial payment of approximately $ 1.1 billion to $ 350 million when certain milestones are reached.

The transaction will give Sanofi global rights over KY1005, a fully human monoclonal antibody that has a new mechanism of action. KY1005 binds to OX40-Ligand and has the potential to treat a wide variety of immunity-mediated diseases and inflammatory disorders.

“The acquisition of Kymab adds KY1005 to our dynamic pipeline, a potential first-class treatment for a number of immune and inflammatory diseases. The new mechanism of action can provide treatment for patients with suboptimal responses to available therapies. ” Said Paul Hudson, CEO of Sanofi. “We understand from our ongoing work on debilitating immune diseases how essential it is to find the right treatment for each patient. We hope to develop this research medicine quickly. ”

KY1005: Promising antibody for inflammatory disorders

In August 2020, Kymab announced that KY1005 met the two primary criteria in a phase 2a trial that studied patients with moderate to severe atopic dermatitis whose disease was not adequately controlled with topical corticosteroids. KY1005 demonstrated a consistent treatment effect versus placebo on several final criteria, including the aczema and severity index (EASI) and additional objective clinical measures.

“This acquisition is in line with our strategy of targeting fundamentally important disease pathways. We believe that OX40L, a key immune regulator, has the potential to rebalance the immune system without suppressing it, providing a promising new approach to treating a number of immunity-mediated diseases. ” said John Reed, MD Ph.D., global head of Research and Development at Sanofi.

The Kymab gas pipeline also includes the oncological active KY1044, an ICOS monoclonal antibody agonist, currently in the initial stage of development 1/2 as monotherapy and in combination with an anti-PD-L1. The acquisition also provides Sanofi with access to new antibody technologies and research capabilities.
