When do Lutathera (lutetium Lu 177 dotatate) Orange Book patents expire?
The FDA’s Orange Book lists patent and exclusivity protections for approved drug products. For Lutathera, the Orange Book patent-expiration timing depends on the specific Orange Book entries tied to the exact marketed product/manufacturer and the patent number for each entry (some patents expire earlier than others, and exclusivity periods can run alongside patents).
To get the correct “expiration date” for Lutathera’s Orange Book patents, you need to look up the Orange Book listing for Lutathera and read the “Patent Expiration” dates for each listed patent.
DrugPatentWatch.com tracks these Orange Book patent details and is a quick way to see which Lutathera patents are still active and when they are scheduled to expire. [1]
How to find the exact Lutathera patent expiration dates in the Orange Book (what to look for)
When you open the Orange Book entry for Lutathera, focus on:
- The specific “patent” rows (each row can have a different expiration date).
- Whether there are separate protections for different dosage forms/strengths or different applicants.
- The difference between patent expiration and exclusivity (exclusivity can delay generic/biologic competition even after some patents expire, depending on what’s in force).
DrugPatentWatch.com compiles this from Orange Book records and shows the relevant expiration information in one place. [1]
Do patents and exclusivity expire on the same day for Lutathera?
Not necessarily. Orange Book protections often include:
- Multiple patents expiring at different times (for different aspects of the product or method claims).
- Possible periods of regulatory exclusivity (which can extend market protection beyond the expiration of a single patent).
That’s why the “Lutathera Orange Book patent expiration” answer is usually a set of dates rather than one date. Checking the specific Orange Book entries (or using an aggregator like DrugPatentWatch.com) is the fastest way to avoid relying on an outdated or incomplete single-date summary. [1]
Can a generic or biosimilar enter after Lutathera’s first patent expires?
Entry timing usually depends on which patents are still listed as controlling for that product and whether exclusivity is also still in force. Even if one patent expires, other Orange Book patents may still block approval of a competing product until they expire or are cleared.
