Maybe they are not confident - seems to be the case with current management, or they are being cautious knowing there maybe a challenge.
Depends how deep BCRX pockets are - not too deep based on current cash flows - they may need a white knight, or litigation funder to mount a serious challenge.
None the less, this is positive news for BTA, the ducks are lining up - shame this and other recent positive news was not about when price was +$3, I would then not be writing this !
cheers
