As a biosimilar launching into a crowded immunology space, Erelzi required the creation of a plethora of marketing materials. To this end, we developed a collection of pieces to aid in effective communications with prescribers, smooth transitions for patients, and rapid uptake for payers. Our suite of resources include visual aids, fully-branded websites for patients and HCPs, several value proposition decks for payers, patient support materials, emails, convention materials, and much more. The messaging centered on the three main pillars of Sandoz biosimilars: Sameness, Savings, and Sandoz heritage, which includes comprehensive Sandoz One Source support services.
