Every one of what you're calling "ample shares authorized for funding" would only cover 2/3 of the P3 trial for B-ABSSSI or who knows what portion of a B-OM P3 or a full complement of B-UC trials. K? What's the plan?
If those newly authorized 300M shares were converted today at 7 cents it would garner $21M. That would last ~18 to 19 months at current spending levels. Costs will increase if and when trials begin.
