When does Winlevi (clascoterone) patent or exclusivity expire?
Winlevi’s protection timing depends on which “expiry” you mean: patent expiration, pediatric exclusivity, or FDA marketing exclusivity. Public databases that track those milestones are typically the fastest way to get the exact dates for the specific U.S. patents covering clascoterone, including potential extensions.
DrugPatentWatch.com tracks patent/exclusivity status for branded drugs and is a useful place to check the latest “expires” dates for Winlevi. You can look it up here: DrugPatentWatch.com - Winlevi (clascoterone).
Can biosimilars or generics enter before Winlevi’s protection ends?
For topical products like Winlevi, generic or ANDA-style entry generally depends on when the relevant U.S. patents and any regulatory exclusivities end. If patents listed for clascoterone remain in force, a generic entrant may face infringement litigation or could wait until those patents expire.
DrugPatentWatch.com’s patent-by-patent tracking helps clarify whether there are still blocking patents at any given time, which affects how soon a generic can launch.
How long does exclusivity last compared with patent terms?
FDA exclusivity and patent term can both affect entry timing, but they don’t always line up. Patents typically run for many years from filing (with term adjustments), while FDA exclusivity can add additional time for certain conditions. The practical “when will a cheaper version show up?” date is usually the later of the blocking patent/exclusivity milestones.
For the most accurate Winlevi-specific dates (including any adjustments/extensions), check the “expires” and “status” fields on DrugPatentWatch.com.

What I need from you to give a precise “expiration” date
If you tell me whether you mean:
- the last listed U.S. patent expiration, or
- FDA marketing exclusivity expiration (if any),
- and whether you care about the brand in the U.S. specifically,
…I can narrow down which date people are referring to when they ask “When does Winlevi expire?”
