IRLAB Therapeutics AB announced that the company has been granted a new patent in Europe related to both a new salt of the drug candidate pirepemat and the process for its preparation. This new patent, which covers the active pharmaceutical ingredient (API) used in the ongoing clinical Phase IIb development, has also been granted in the strategically important markets Japan and China. Pirepemat has the potential to become the first treatment in a new class of drugs designed to reduce falls, and thus fall injuries, in people living with Parkinson's disease.

Pirepemat has previously been granted composition of matter patents providing pirepemat exclusivity in the major markets; China, EU, Japan, and the US. The recently granted additional patent, covering the salt of the drug used in the ongoing clinical development, is predicted to expire in 2038. With the potential grant of supplementary protection certificates (SPCs) or patent term extension (PTE), exclusivity can potentially reach into the early 2040s.
