I think all of the available answers to questions recently posted here are in that video.  I thought it was worth a relisten despite the reminder of so many missed time-lines.  

At the 34 min mark Don mentions that a 30-day covid treatment would cost $800. He does not mention Cdn or US in that instance but I think all his figures are in US.  

When Don refers to a patient cost of $7/pill (says it is $6.85 in one instance) or $5,000 per year he specifically mentions US$ and it was in the context of the price of the pill for CVD patients later on, and that the initial batch of apabetalone for covid use will cost considerably more.   For a 30-day treatment $800 US per patient equals 800 / 30 / 2 = $13.13 US per pill.

His reply to a question about the 'per pill margin' was: "That is an unknown at this stage".  This only means that they, at that time, had not signed a mass production contract agreement yet.
