Today& #39;s "breakthrough" announcement is unlikely to be any breakthrough.
1. Convalescent plasma has no randomized trials. It contains many antibodies that have no neutralizing effect. If it has efficacy, it will be be relatively modest, at best.

2. There are no new, large-scale randomized trials that have been completed with repurposed drugs; the combination of JAK inhibitor (Baricitinib) and Remdesivir may have results but it only has 400 patients and no replication https://investor.lilly.com/news-releases/news-release-details/lilly-begins-phase-3-clinical-trial-baricitinib-hospitalized">https://investor.lilly.com/news-rele...

4. True breakthroughs in medicine are exceedingly rare.
It is even more rare—actually unprecedented—for they to be announced by a politician, no less a @POTUS
In the context of other magic and cures that have similarly been proclaimed in recent months, this all aligns well.

5. It& #39;s even worse than this. There is no breakthrough and the @US_FDA commissioner @SteveFDA has caved to Trump& #39;s pressure (including yesterday& #39;s tweet) to promote it as if there was one.

Outrageous to listen to @realDonaldTrump @secAzar @SteveFDA claiming a 35% improved survival in an observational preprint study compared w/ late-treated patients. There& #39;s no evidence to support any survival benefit. 2 days ago FDA& #39;s website stated there was no evidence for an EUA
Here& #39;s the 8/12 preprint the claim is based on
https://www.medrxiv.org/content/10.1101/2020.08.12.20169359v1.full.pdf
These">https://www.medrxiv.org/content/1... were 2 exploratory analyses without control patients, with multiple confounders, eg early v late Rx
The improvement of survival with a high antibody level was a post-hoc determination from stored samples
