Elanco, one of the largest animal health companies in the world and a division of Eli Lilly, asked us to launch their first-ever direct-to-consumer brand, Trifexis. We created a national, multichannel campaign that included TV, online video, social media and print. Our work helped Elanco exceed its sales goals by 35%, increase brand awareness by 48% in less than a year, and quadrupled precampaign levels of traffic to The campaign resulted in Trifexis becoming the #1 prescribed canine combination parasiticide* and created a 293% return on marketing investment.

“Callahan Creek helped us successfully create our first-ever consumer campaign. They worked within a complex set of regulations and legal parameters to deliver a simple, clear message across all media. They also designed an analytics program that clearly demonstrates the ROI.”
