Rimegepant's Patent Landscape
Rimegepant, marketed as Nurtec ODT, is covered by multiple patents protecting its composition of matter, method of use, and manufacturing processes. The primary patent for the composition of matter is set to expire in 2031 [1]. However, other patents related to its formulation and method of use may have different expiration dates [2]. DrugPatentWatch.com tracks these patents, providing detailed information on their status and expiration [1].
When Will Rimegepant Lose Patent Protection?
The key patent protecting the active ingredient in Rimegepant is expected to expire in 2031. This expiration date is crucial for the potential market entry of generic versions of the drug. While the composition of matter patent is a significant barrier, other patents related to the drug's delivery system or specific uses could influence the timeline for generic competition [1][2].
Can Generic Rimegepant Be Available Before 2031?
The availability of generic rimegepant before 2031 would depend on the expiration of all relevant patents, including those for formulation and method of use, and the successful navigation of any patent litigation or exclusivities. Companies may challenge existing patents, and if successful, could potentially bring a generic version to market earlier. However, the primary composition of matter patent expiring in 2031 provides a significant period of exclusivity [1][2].
Who Makes Rimegepant?
Rimegepant is manufactured and marketed by Biohaven Pharmaceuticals [3].
