You’re playing word games, IMO. We can now say with very high confidence that Stimuvax is not showing Grand-Slam-into-San-Francisco-Bay efficacy in the trial in question.
Really? That really depends on how much alpha was allocated to IA2.
Nono and TGW both agree that Kirkman has said they were using OBF.
That means efficacy is now around 0.80 or higher to have failed the last interim (I don't remember the absolute number - but I did the calculation several months ago and it was near enough as makes little difference.)
