Planning for Celebrex was at Bcom3 Group's Starcom, Chicago, a vestige of when creative duties on the brand -- now at WPP Group's J. Walter Thompson, New York -- were at Bcom3's Leo Burnett USA, Chicago.
Bextra had no previous media agency since it was just cleared by the Food and Drug Administration this month. Interpublic Group of Cos.' Deutsch, New York, handles creative.
Billings for the accounts were unclear. CMR figures show Celebrex spent $103 million through August of this year. Bextra will likely be heavily promoted, although the companies are expected to try to convince doctors of its efficacy before reaching out to consumers.
Celebrex launched in 1999 and has gone up against Merck & Co.'s Vioxx. Merck also has a Bextra competitor waiting for the FDA's blessing.
