Karin, there are still two weeks left in Q3. Maybe Leo hasn't made a final decision yet. As you know, not everything is set in stone in clinical trials.
I'm sure Leo hasn't forgotten the constant attacks on his company so their potential life-saving drugs can't reach the market and save lives. So why give more ammunitions to the enemies by potentially jeopardizing the trial? Let's face it, no matter what he says, it'll be twisted into something negative.
Sorry to hear abut your friend! May he/she rest in peace.
