That's difficult. We should just say at the start that when we're looking at a new first-in-class, they're often recommended by Health Canada on the basis that their potential benefits outweigh any safety issues. When we're looking at it, just to give you an example, often these first-in-class agents are approved based on their evidence of effectiveness on non-clinical end points.
For instance, concerning a medication that we looked at for patients with kidney failure on dialysis who had elevated parathyroid hormones, we knew from studies that patients who had elevated parathyroid hormone levels had a higher risk of breaking their bones and dying. This new medication was released that showed it could lower that level of parathyroid hormone.
Actually, as a physician, I know that patients don't care about their parathyroid hormone level. They want to feel better, they want to live longer, and they want to prevent complications from happening.
But the evidence, when it's brought to Health Canada, is at a relatively early stage. So we have this information that it makes a reduction in this laboratory test, but no information as to whether it makes people feel better or live longer. Some of these medications, this one in particular, came with a price tag of about $4,000 to $23,000 per year. So there's a tremendous amount of uncertainty in trying to determine whether a reduction in a laboratory test will produce clinical benefits.
We've seen in people with acute heart attacks that if they have lots of ventricular premature beats, that says they're at higher risk of dying. We have a class of—
