The FDA maintains several “color books” that provide essential information on approved drugs and biologics. Among them, the Orange Book and Purple Book stand out as vital references for sponsors, regulators, and competitors. Accurate and timely updates to these listings are critical to protect intellectual property, manage exclusivity, and ensure compliance.
Understanding FDA’s Orange and Purple Books: Why Accuracy and Timeliness Are Critical
How the Orange Book Shapes the Market
The Orange Book, formally Approved Drug Products with Therapeutic Equivalence Evaluations, catalogs FDA-approved small-molecule drugs and their generics. NDA holders must submit new patents within 30 days of issuance and promptly delist when necessary. These updates influence how generics are developed and certified, directly impacting market competition and exclusivity rights.
The Purple Book as a Biologics Roadmap
The Purple Book, officially the Database of Licensed Biological Products, provides a reference for biologics, biosimilars, and interchangeables. BLA holders are responsible for submitting exclusivity and product details to ensure the database reflects accurate pathways for competition. This resource helps companies track exclusivity periods, understand competitive landscapes, and prepare for biosimilar entries.
Where Green and Blue Fit In
The FDA also manages the Green Book, which covers approved veterinary drugs, and the Blue Book, which primarily reports on FDA budget and expenditures. While these resources are less central for human drug and biologic sponsors, mentioning them underscores the FDA’s broader framework of transparency. For most companies, the Orange and Purple Books remain the top priorities.
Addressing the Practical Pressures of Updates
Orange and Purple Book updates often overlap with demanding regulatory calendars. Teams balancing submissions, audits, and planning must also account for two types of deadlines: immediate filings for new patents or exclusivity grants, and annual renewals required each year between October 1 and December 31. These renewals confirm to the FDA that products are still being manufactured and sold. Aquila ensures both types of SPL submissions are filed on time and without error.
