Drug news: Alcon picks up Zyclorin from Sirion

Alcon finally puts some substance into its dry eye portfolio by grabbing Sirion's Zyclorin (cyclosporine A 0.1%). Gotta double the Allergan ante I guess.

Zyclorin is a bit of a dark horse (at least to those of us who don't consult for pharmaceuticals) - one of those you hear no buzz about until they're almost done. It's 0.1% cyclosporine A and according to the NIH clinicals site, a Phase III study was completed almost two years ago. The Sirion site simply indicates it's in Phase III and Alcon is tight-lipped about the status.
