Might be a good idea for HZNP to buy the company. Why pay royalties. Lots of pipeline stuff. Funny how Takeda is many times linked to HZNP initiatives like using HemoShear's technology. They bought out TW's last company and I think there is still lines of communication open between TW and Takeda.
Take a look at HemoShear's pipeline - would be a great addition to HZNP's growing stable of potential products (some already are, but in this case buying the cow gives you all the milk).
