When does the Strensiq (asfotase alfa) patent expire?
I can’t determine a specific Strensiq patent expiration date from the information provided. Patent expiry depends on the exact patent(s) listed in each country and on whether exclusivities (such as supplementary protection certificates, pediatric extensions, or data exclusivity) apply.
What you need to look up to find the exact expiration date
To get the correct expiration date, you need the jurisdiction and the specific patent family. The key inputs are:
- Country/region (for example, US vs. EU vs. UK vs. other markets)
- The specific patent numbers in the Strensiq patent list for that market
- Whether an SPC (EU) or other extension exists, which can push effective market exclusivity beyond the basic patent term
How to get the date quickly in the US vs. Europe
If you want, tell me which country/market you care about (US, EU, UK, etc.) and I can outline the fastest way to locate the relevant expiry using that system’s patent/exclusivity sources. Without that, there’s no single reliable “Strensiq patent expiration date” to cite.
Does “patent expiration” mean the same thing as “market exclusivity”?
No. Even when the underlying patent term ends, marketed availability can still be constrained by:
- Extension mechanisms (for example, SPC-style protections in Europe)
- Data/exclusivity rules that restrict the ability of follow-on products to rely on the original clinical data
Which product exactly matters (and why)
Strensiq is asfotase alfa. Patent life can differ by:
- Specific formulation, dosing regimen, or manufacturing/process claims
- Different patent families tied to separate jurisdictions
Tell me your target market and I’ll narrow it down
Reply with the jurisdiction you mean by “patent expiration date” (e.g., “US” or “EU/France/Germany/UK”) and, if you know it, the patent number or the regulatory listing you’re looking at. Then I can give you the specific expiration date(s) for that market.
