This trial is one that's happening in over a hundred countries around the world, and Canada was one of the early folks to sign on to it. In fact, we helped design a lot of it.
It's a randomized trial, so patients are assessed for eligibility. Then they get one of the treatment arms or the standard of care.
The current treatment arms in Canada include one medication called Kaletra, or Lopinavir/ritonavir, which is typically used for HIV, and very successfully so. It was evaluated in a relatively small trial in China without the ability to be confident in its effect, and it therefore needs to be tested in a large number of people. There are a number of trials happening that will have larger numbers, and this is one of those. The numbers of randomized patients are in the many thousands, as opposed to many hundreds.
