Let's not re-start the clock here with a new type

Let's not re-start the clock here with a new type of administration. That would only delay the trials further, costing more lives. Let's get an EUA for the 80% survival benefit we've got now, and then refine afterwards. A small adjunct trial for IV can always be run at a later date to prove safety if necessary. Don't let the perfect be the enemy of the good. There will be plenty of future trials where the IV dose can be tested.
