That China study was one of six studies they were doing in China and at the last interim look on the other 5 trials they stopped the trials so they could say that they didn’t fail. That’s what I remember reading in some article at the time. Then all of a sudden next thing I heard was FDA approved EUA with a 4 days quicker recovery that wasn’t even their primary end point until the last interim look and was changed to that and still approved… then with no lab results whatsoever from any lab testing showing benefits of any kind…it’s a miracle that they got the full BLA approval from Trumps administration FDA before they left office. Amazing timing with way less than the normal 10 month BLA review. Funny how politics influence some decisions.
