the government can fix this situation in a variety of ways - price ceilings, subsidies, even government production of drugs for rare diseases. I'd think they should require cooperation with the equivalence studies, and possibly foot (part of?) the bill for those studies. Try to minimize the downsides of their (overall important and helpful, if perhaps taken a bit too far) regulations that cause the problem. Price ceilings for anything with a government-granted monopoly would also probably be good, but that's... not exactly the issue here, since the drugs in question have gone off-patent.
