Realistically it's a crap shoot on a political level... as with any pharmacological entity. The data that exists today (coming directly from the company) from what I've seen would give it a leg up on morphine (the standard) w/ a pretty substantial reduction in vomiting, constipation, as well as respiratory safety events. Additionally, it is cheaper than the current standard of care.
Not to mention, the current opioid situation, where this may be a suitable counter for the ongoing epidemic.
My two cents. I'm in with 50K shares @ 1.57.
