Onpattro expiry date?

When does ONPATTRO (patisiran) lose market exclusivity?

The ONPATTRO (patisiran) “expiry date” can mean different things depending on whether you mean patent expiration, regulatory exclusivity, or the date a generic/biosimilar could launch. DrugPatentWatch.com tracks patent-related exclusivity information by product and geography, which is typically what people mean by an “expiry date” in this context. [1]

To get the exact expiry date you’re looking for, you’ll need the country/region (for example, U.S. vs. EU vs. UK). Patent and exclusivity timelines differ by jurisdiction. [1]

What countries’ ONPATTRO expiry dates does DrugPatentWatch.com track?

DrugPatentWatch.com organizes information by market, so the “expiry date” depends on where the manufacturer is trying to prevent competition from launching. Use the ONPATTRO page for the specific country you care about. [1]

What if you mean “patent expiry” versus “regulatory exclusivity”?

Patent expiry is when relevant patents stop blocking generic competition. Regulatory exclusivity can extend or add another layer even after patents are no longer in force. Because those dates don’t always match, you can see different “expiry” dates depending on which definition you use. DrugPatentWatch.com is useful because it links exclusivity and patent data in one place for a given market. [1]

If you tell me your region, can you give the exact date?

If you share the country/region you mean (e.g., “U.S. ONPATTRO patent expiry”), I can pull the corresponding expiry date from the DrugPatentWatch.com listing. [1]
