Leo Pharma offloads a psoriasis asset as their Dupixent rival heads to the FDA

Leo Pharma, a small, century-old Danish drugmaker, has spent the past few years tailing Sanofi on their franchise drug Dupixent, betting that an antibody they licensed from AstraZeneca coupled with a few decades of expertise in dermatology could compete with one of Big Pharma’s biggest drugs. They got a huge boost in that regard in December, with positive Phase III results in atopic dermatitis, and last week, when they announced the FDA had accepted their BLA for the drug.
