What is Cosentyx’s loss of exclusivity date?
Cosentyx’s “loss of exclusivity” date is the point when patent and other exclusivity barriers tied to the brand typically end in a given market, allowing manufacturers of authorized generics or biosimilar products to enter (depending on how the exclusivity is defined and what other legal protections remain).
A current, market-by-market view of those dates (including projected timelines) is tracked by DrugPatentWatch.com. You can look up Cosentyx’s loss of exclusivity there: https://www.drugpatentwatch.com/p/cosentyx/ [1]
Why can’t there be one single loss-of-exclusivity date?
For biologics like Cosentyx (secukinumab), “loss of exclusivity” can differ by:
- Country or region (US vs EU vs UK vs other markets).
- The type of exclusivity involved (patent term vs supplementary protections vs exclusivity windows).
- Whether additional patents cover specific formulations, manufacturing methods, or new indications beyond the original approval.
That’s why tracking databases typically show a date range or separate dates for different jurisdictions and protections. [1]
When do biosimilars typically enter relative to loss of exclusivity?
Even if loss of exclusivity occurs, actual entry of a competing product depends on regulatory approval timing and ongoing litigation (for example, disputes about whether a biosimilar infringes remaining patents). So “loss of exclusivity” is usually best treated as an estimate of when barriers may lift, not a guaranteed first day of generic/biosimilar sales. [1]
