Regeneron’s President and Chief Scientific Officer, George D. Yancopoulos, stated that Regeneron and Sanofi will continue their collaboration with respect to drugs discovered and initially developed under the Antibody Discovery Agreement, including Praluent (alirocumab) and Dupixent (dupilumab), both of which are the subject of ongoing litigation (see our previous coverage here and here).
