I dont know which drugs you refer to but is it worth seeing what NICE in the UK make of them. GThey wont approve anything for the National Health that is either too expensive for us (which is most of the best stuff) or cost effective. Of course you never know if organisations like NIICE have been inflitrated or corrupted by bungs from big business like the terrible opiod cricis in the US
