No. It is not much ado about nothing.
It is about off-label use that is life-saving when used correctly or not.
There are many drugs used via off label use for benefit.
Studies will never be done as there is no financial incentive. But since these off label uses are not politicized, virtually nobody is concerned.
With the Wuhan Corona Virus it is different.
The concern here is a broad-based public health issue driving these many studies.
Studies that passed human studies committees for approval by the way.
You can’t do a randomized, prospective, double-blind study on humans with drugs, unless you get approval first. Approval from a human studies committee.
You cannot get approval from a human studies committee without preliminary evidence.
Preliminary evidence includes physiologic mechanisms purported and clinical data if available.
(Sometimes incidental clinical data. i.e. in this case if lupus HCQ-treated patients seemed to do much better, this data theoretically might be taken into consideration).
