The outstanding shares now is about 50 to 60 mil and depending upon whether future warrants are exercised as well.
But you are correct in that RXII ownership is up around 42% and 46% including previous institutions though.
In addition I don't think this is the last of a large stake that is taken for RXII. As more institutions get wind of RXII working on a scarring drug more will buy shares for two reasons:
1.) Early results show that RXI-109 works better than placebo 2.) There are "Zero" FDA approved drugs for scarring meaning that Rxi has the potential to be the first company ever approved for scarring.
