Merck discard jumps straight to the top of the chart of the most expensive drugs in the US at $1M-plus

Back late last fall, when Eiger Pharmaceuticals $EIGR completed its victory lap with an old Merck discard it had developed for rare cases of progeria, the company told reporters that it was thinking of pricing the newly dubbed Prokinvy at the usual rate reserved for ultra rare diseases. Merck abandoned the drug years ago after giving up on a cancer indication, and let Eiger have it for Progeria several years ago without tacking on any milestones in the deal.
