"Big Pharma was negligent when Polymedic was in bankruptcy court back when, allowing Leo to dark horse a bid and nab everything they owned, including the golden Brilaciden package! Go Leo!"
It remains to be seen if that was negligence or just smarts.
I suspect that even then Big Pharma had access to data that was not available to the pink sheet penny stock speculator who holds brilacidin to be the savior of mankind.
Nowadays that would be even more true - the complete data package would be available to any BP suitor, and it seems that what they have seen from the various previous clinical trial programs (all (aborted, it would seem) has scared them off.
BTW, it's brilacidin, not "Brilaciden".
