To be honest with you, as a physician, I think I would probably very rarely if ever even prescribe it." Still, he said, there appear to be a "insignificantly small number of very difficult-to-treat patients that, for whatever reason – and I'm not sure we totally understand why that is" – are helped by the drug.
