Eli Lilly is moving its U.S media account to Publicis’ Zenith which concludes the drug maker's nearly 20-year relationship with Omnicom’s OMD worldwide.

OMD was a finalist in the pitch, and WPP and Dentsu also participated in the review, according to a person close to the situation. The review, which kicked off in June, was handled by Medialink.

Publicis declined to comment. WPP, Dentsu, and OMD weren’t immediately available for comment.

Eli Lilly is the maker of drugs like the antidepressants Prozac and Cymbalta, and the diabetes drug Trulicity. The pharmaceutical giant had disclosed 2020 worldwide ad spending of $1.1 billion, primarily for TV, radio, print media and internet advertising. Ad Age Datacenter estimates the U.S. portion of that spending to be at $869 million. A person close to the situation said Eli Lilly will likely be looking to increase its ad spending moving forward.

"As part of our Marketing transformation goals, Lilly aims to create remarkable experiences within the consumer journey, fueled by both human insights and data," the company announced in a statement. "Lilly looks forward to working with Zenith, part of Publicis Groupe, as our new media agency of record. Together, we will partner to deliver these remarkable experiences to patients and help support the future growth of the business."

Publicis Groupe has been on a hot streak, scoring five big media wins in the last nine months alone. In February it won media agency-of-record status for Inspire Brands, the parent of Arby’s, Baskin-Robbins, Buffalo Wild Wings, Dunkin', Jimmy John’s and Sonic. It brought home Stellantis in April and Walmart in August. Earlier this month it won the high-profile media account for Facebook, now known as Meta.

Lilly's move is a blow for Omnicom, which recently secured some significant media wins. In October, the holding company won Chanel’s $500 million global media account. Earlier this month Omnicom won media business for brands like iFit and British Airways.
