If FDA is a major barrier to bringing drugs to market, is it possible set up trial in other countries with less regulation as well as trial cost? I would imagine that for stuff such as cancer there should be significant demand for trying out drugs that are still on trial - especially in other countries because they don't even get to participate normally.
