At this stage Pfizer are probably playing the waiting game. SBP have only just enough money to get through the Australia Phase IIb trials. Ideally they need a lot more money to carry out Phase IIb in the USA, that way any results will immediately be recognised by the medics that count in the marked that counts. As it is now they need good early results from the Aussie Phase IIb trials to generate interest from the big Pharmas and hopefully get an agreement of some sort in place to secure more finance. SBP are at the mercy of the big boys and poor results from Phase IIb trials will see them in a lot more strife.
I still picked up a few more, at these prices I like the gamble.
