The CDER Office of Prescription Drug Promotion (OPDP) is planning to study multiple indications in direct-to-consumer (DTC) TV ads. A *Federal Register* [notice](https://www.govinfo.gov/content/pkg/FR-2021-03-04/pdf/2021-04472.pdf?ref=fdaweb.com) says the study “will provide preliminary information on whether consumers face challenges when multiple indications are promoted in a single television advertisement. The study also will explore whether similarity of the indications affects participants’ likelihood to recall and understand the indications, and whether its effect would be positive or negative.”

The notice says the study will test three types of fictional DTC ads — one that promotes a single indication, one that promotes an indication plus a similar indication, and one that promotes an indication plus a dissimilar indication — in two different medical conditions.
