I think 'allows recruitment to commence' means exactly that and I'd be surprised if one needs to read anymore into that.

What I don't get is why the ethics approval in Canada would have prevented them from at least starting the trial in Brazil sooner.  I doubt they would be linked but I'm no expert on ethics approvals.  Only 100 patients in Canada and Brazil, but how many in each?  50/50 or does it really matter.  I have no idea.

Anyway, hopefully the trial is successful because if it is the results would/should be known before the June 2023 warrants expire.  That might be the only way those don't end up in the dumpster as well.  There was a fair amount of trading volume today compared to yesterday.  Did some folks know the result prior to the announcement?
