On the first part.i have no obligation to be a saint. This is an abusive board. PERIOD. In fact, way back, I showed a tonne of tolerance this abuse. I don't have to do it in perpetuity, I am not claiming any good person of the year awards either.
Understand this also, speaking with confidence about highly specialised and complex science when in fact not a scientist is in itself arrogant. Again, not claiming any awards, but if all you see is arrogance coming from me then you are blind. At least I am actually a scientist and in drug development in particular.
Second: My view has been this for a long time, screen them after infection (so as early as possible how far before is no longer consistent with anti viral mechanisms no one can tell exactly, but icu stage is by far the least likely) and then treat them, you want to treat everyone in the trials to sort out what's best, even better but CHECK. I jave seen no narrative or document from the company that suggests they are screening for deficiencies in their own trials. So I assume they do not.
Activ is far more clear.
They don't just check before treatment, but throught the primary endpoint monitoring period. This will answer if in some people auto antibodies are present already earlier and if not, when. Maybe there will be a mix of cases, who knows? That's why you have to check. In those cases, the earlier the antibodies are there (ideally as soon as they tested the first time) the more likely it is that they are in fact causative of severe disease (if patient on placebo actually get severe disease). If they only find cases where these showed up towards the end of that monitoring period and the patients became severely ill at the same time or shortly after, then there is a good chance this not causative or a driver but simply a symptom. This information will obviously inform the design of the phase 3, either the inclusion criteria and/or the number of endpoints (if they make separate ones for + or - minus antibody. Note that primary endpoints have MUCH greater value (especially when it comes to marketing authorisation) if they are pre-specified. They are also checking ifnb as well, for the same reasons but probably it is also a tick in the safety checklist (they want to see if the using the drug induces autoantibodies against said drug, which would mean autoantibodies against the natural protein as well). I don't think there is a big risk here, it isn't unheard but seems less likely to happen for ifn b.
