I do think that they are laser-focused on the BLA, since they know that every additional month will cost them 3-4m - money they hardly have at this point. As trding has already pointed out, we should know soon whether FDA will still require 700mg safety data or accept 525mg, and even if they don't, end of September for full BLA submission seems very well possible.
