Signing a deal worth up to $1.5bn, Teva is hoping Sanofi’s dominance in immunology via the mega-blockbuster Dupixent can help it compete with frontrunners Pfizer/Roivant and Merck & Co in a new anti-inflammatory space.

Teva received a “package of commercial side-deals” for agreeing to halt generic competition to Cephalon’s Provigil (modafinil) throughout the EU, which it “would not have achieved without committing to staying out of the market,” according to findings by the European Commission.
