"I think NWBO might still be sitting on a healthy war chest of funds, in part lots of money still left over from Woodford fundings. They might not need any more funding until late 2016 or into 2017."
I want to believe you Evaluate, but why would they fund at such a low valuation recently if they were sitting on a pile of money?
The only explanation I can think of would be if moneys from Woodford were constrained in their use in some way, and some new need arose (maybe a CI for sale? Or hiring her special investigator...), outside of those agreed or contracted constraints. Myself I don't know if those kind of constraints exist.
For example, the funds from Woodford might be constained to be used to fund the DCVax-L trial.
