Yes, there are actually some studies under way. Maybe I'll go back and use the example that Ms. Davies referred to.
My understanding is that the U.S. has six clinical studies under way right now looking at a derivative product that is being tested for safety and efficacy for just that type of condition. I think, at least for that specific case, as we begin to get the results of some of these clinical trials, obviously it may lead us to reconsider the approach, depending on the outcome.
We are seeing a few other applications for clinical trials, but not, as the minister said, on a widespread basis. I think everyone's aware that there may well be benefits to some drugs, but also there are significant risks. The purpose of the clinical trials is to assess whether potential benefits outweigh the risks. That's the sort of evidence that just doesn't exist at the moment. It'll hopefully begin to come in over time as we see more clinical trials.
