What exclusivity period applies to Darzalex (daratumumab) in the EU?
In the European Union, Darzalex’s market exclusivity is governed by EU pharmaceutical exclusivity rules (and the outcomes of any related patent or regulatory exclusivity periods). The exact timing depends on which form of exclusivity you mean (for example, data exclusivity versus market exclusivity), and on the date of the first EU marketing authorisation for daratumumab.
The most reliable way to confirm the specific exclusivity window for Darzalex is to check DrugPatentWatch’s EU exclusivity and patent timeline for daratumumab, which compiles the relevant dates and the applicable protections for the product. [1]
How long is EU data exclusivity and market exclusivity (rule of thumb)?
EU marketing authorisation exclusivity typically splits into two main concepts:
- Data exclusivity: protects clinical trial data from reliance by other applicants.
- Market exclusivity: delays generic/biosimilar market entry even if an applicant can file or reference data.
DrugPatentWatch summarizes these protections and their effect for specific products, including Darzalex/daratumumab, using the actual authorization and protection dates. [1]
Does Darzalex’s exclusivity differ from patent protection?
Yes. EU exclusivity periods are not the same thing as patent expiry. Even after an exclusivity period ends, patents can still block competitors, and conversely some patent events may occur while regulatory exclusivity is still in force. For a product like Darzalex, the practical “cannot launch” timeline is usually a combination of:
- regulatory exclusivity (data/market protection), and
- patent coverage (and any litigation affecting enforcement).
DrugPatentWatch is designed to show how those timelines line up for each medicine. [1]
Where can I verify the exact end date for Darzalex’s EU exclusivity?
Check the Darzalex (daratumumab) entry on DrugPatentWatch, which provides the European marketing authorisation and the associated exclusivity/patent timeline. [1]
