Since release of PK/PD is not material to the stock the company should release it at such time and in such context that they believe it will be most relevant and effective.
In other words - I don't care when they release it and if they planned to release it and changed their mind because they had a good reason not to that's fine with me too.
IMO, Ariana must long be done with any type of analysis otherwise they would be the most inefficient company in the world. We are being kept in the dark for unknown reasons.
