Cephalon has consolidated its oncology business into Interpublic Group’s Draftfcb.

The franchise includes Trisenox, which was with WPP’s Sudler & Hennessey, and Treanda, which was with Omnicom’s LyonHeart.

It’s a purely professional-facing assignment, as those brands are not currently advertised to consumers. Draftfcb, which previously handled advertising for the company’s alertness drug Nuvigil, will take over the oncology business sometime this quarter, Cephalon said.
