It's likely in there, you just want them to be very emphatic about it. There is no placebo arm. I think that is the most obvious answer. If you don't have enough patients for the placebo arm because most patients have crossed over, then making more patients defer their treatment and die sooner, for no reason, is unethical.
The placebo arm was not fit for purpose. The placebo arm is short. They have disclosed that they needed an external control arm, and they have likely discussed this entire set of facts with their regulators ad infinitum. Emphatically explaining that would simply be disclosing matters that might tip the regulators hand, or suggest that they are likely to have a positive disposition, IMHO. That's not the job of such an article.
Of course, I know you will interpret the entire things the opposite to whatever I say. But that seems to me the most obvious answer.
