Sanofi is acquiring Kymab, a clinical-stage biopharma company developing fully human monoclonal antibodies, for an upfront payment of approximately $1.1 billion and up to $350 million upon achievement of certain milestones.
The transaction will result in Sanofi having full global rights to KY1005, a fully human monoclonal antibody that has a novel mechanism of action.
KY1005 binds to OX40-Ligand and has the potential to treat a wide variety of immune-mediated diseases and inflammatory disorders.
“The Kymab acquisition adds KY1005 to our dynamic pipeline, a potential first-in-class treatment for a range of immune and inflammatory diseases. The novel mechanism of action may provide treatment for patients with suboptimal responses to available therapies,” said Sanofi CEO Paul Hudson.
“We understand from our ongoing work in debilitating immunological diseases how critical it is to find the right treatment for each patient. We look forward to rapidly developing this investigational medicine.”
