Sanofi Replaces CEO Hudson, Names First Woman at Helm

Sanofi abruptly replaced Chief Executive Officer Paul Hudson after a massive research spending boost failed to deliver rapid results, appointing its first female leader, Merck KGaA’s Belén Garijo.

Hudson worked to shake up research to replace sales from a looming patent cliff for its top-selling drug Dupixent, but his efforts didn’t pay off.
