When does Takhzyro (lanadelumab) lose patent protection in the UK?
You can’t get a single reliable “goes off patent” date from general info alone. Patent expiry depends on the specific UK patent(s) covering Takhzyro (and any related supplementary protection certificates, or SPCs), and different patents can expire on different dates.
What usually determines the exact UK “patent expiry” date for a drug like Takhzyro?
For a biologic medicine, the relevant UK timing is typically driven by:
- the expiry of the underlying UK patents covering the product or process, and
- any SPC expiry if an SPC was granted for one of those patents (SPCs can extend market exclusivity beyond the basic patent term).
Those rights have to be checked patent-by-patent for the UK (and often across multiple jurisdictions because filings can differ).
How can I find the precise UK patent/SPC expiry date for Takhzyro?
To identify the exact UK date, you (or I, if you share details) would need to look up Takhzyro’s UK patent family and any SPCs for lanadelumab, then identify the latest expiry date that still blocks generic/biosimilar competition.
If you tell me either of the following, I can help narrow to the correct UK expiry date:
- the patent number(s) you’re seeing, or
- the SPC/patent record you’re using (link or identifier), or
- whether you mean “patent expiry” specifically, or “end of UK market exclusivity” (which can differ from patent expiry).
Can UK biosimilars enter right after patent expiry?
Even if a patent expires, biosimilar entry can still be affected by:
- other still-in-force patents in the same family,
- SPCs that extend protection,
- regulatory exclusivity/market protections that are not purely patent-based, and
- ongoing litigation or patent challenges that delay launches.
So “end of patent” does not automatically mean “immediate biosimilar availability.”
If you want, I can look it up precisely
Share the Takhzyro identifier you have (brand, active ingredient lanadelumab is fine) plus either a link or patent/SPC number you’re looking at, and I’ll map it to the UK expiry date(s) and explain which one is the practical date people mean when they say “goes off patent.”
