They definitely will not need to secure any new funds. They now have all the money they need. Think they are up to what, 75 mil now in cash? With much more potentially coming in (EU approval and selling milestones for upwards of a quarter of a billion more cash).
And i believe a total over 10 years of 95 million was spent on their most recent approval, so no, they don't need more cash.
The only dilution that will happen are rewards of stock for the great work their employees have done. And that will be it.
