Better yet look at it like this,

if you wanted to buy 4.5M shares on open market in the next week how high you think this baby would go ? Seems to me very unlikely any big player would do this on open market. Hepalink just buys another 4.5M shares for almost 10% below market value and without volatility. If you want a big position, private placement is the way to go. 

One question for the board :

i think its mentioned that an arm of the trial is being conducted in china. Since hepalink is in china would it be not too far-fetched to assume that maybe the blinded data to rvx isnt as blinded to hepalink and that they are very aware of the effect of apabetalone is having on their patients and hence keep pumping money into rvx..? And also its mentioned that hepa is considered an “insider “ due to their ownership.  

Excuse me if any feel like i am going off in this conspiracy direction its just a thought  i had and i cannot prove it with evidence
