And then everyone will agree they weren't dead to begin with.

The Telegraph post has this link to the ReAnima project, but there's no content there (or rather, there's a login page). Here is the official PR from the company. Here is the trial. There's no technical information on either page, in terms of what exactly they intend to do. They talk a lot about "BQ-A", which is their name for the (secret?) active substance they're using.

They hope to achieve:

Primary Outcome Measures: Reversal of brain death as noted in clinical examination or EEG [ Time Frame: 15 days ] [ Designated as safety issue: No ]

The study stared in April 2016 and will conclude in April 2017, presumably because it'll take them that long to "recruit" the 20 participants they're hoping to get.
