Well, I must disagree. Every raising I have seen occurred when the organisation needed money. BLT don't need money, because they raised enough last time to get them through the trial process. If the trials fail, there won't be any development, so they won't need any money ["need" vs "want"]. The time they will need money is on efficacy, when they will need a bucketload of cash for development - and that's when the SP will make it easy for them. And to me, that's just about the only scenario that makes sense.
