Certainly can't afford dilution at these prices.
They could have funded phase 1b with the $2.5 million from Hawes in June. A successful trial would have gotten the buzz going again and generated much more investment/higher share price.
Then, they could have raised money at say $1 per share or higher for P3 launch. that's hindsight.
Maybe we can hope that the NIH picks up trial costs with $9 billion to them from the stimulus.
