Then on what other basis do you believe they decide which orphan drugs to cover and which not? I don’t have insider knowledge but nonetheless I’m fairly certain it’s not based on pure random chance. If the implication is that it’s based on whatever political or lobbying faction is in vogue, that seems to be even worse than an economic measure?
