Last week, the FDA published a final version of the Product Name Placement, Size, and Prominence in Promotional Labeling and Advertisements.
FDA has been remarkably active on this topic, as this is now the third update to the guidance in the past five years. People who have been following this guidance will be pleased to hear that there's little new. Though there are many changes, there are no substantial changes from the 2013 version. The most significant development in the new guidance is the provision of examples demonstrating FDA's principles about prominence of the product name.
If you'd like a quick overview of the guidance, I suggest this one from Intouch Solutions.
