Xspray strives to obtain patents both for composition and methodology, and this new patent claims an amorphous solid dispersion (pharmaceutical composition) of dasatinib.

"The new patent for HyNap-Dasa has the broadest scope of all our composition patents in the US and makes it significantly more difficult for other companies to launch a dasatinib product based on amorphous solid dispersion formulation in the US market during the lifetime of this patent, i.e. up until 2033", says Per Andersson, CEO of Xspray.
