Cash and Burn:
They are raising cash since August 12 it seems, planning to sell shares worth about 1/3 of current mkt cap, which is insane (announcing 2 days after releasing a bullsh*t article where the FDA basically just said "okay we agree you should test this on 100 people."
They will continue to burn cash, then whenever they release something like this, they will raise again and dilute shortly after.
