Raptor Pharma slides again, Favus reportedly out negative

|About: Raptor Pharmaceutical Corp. (RPTP)|By:, SA News Editor

It's been a rough couple of sessions for Raptor Pharmaceuticals (RPTP) as the shares are off some 9.5% since last Thursday (although still up ~116% YTD).

The company could have done without comments out of Favus, where analysts have reportedly called Procysbi "a situation akin to Acthar Gel, with one major difference: The availability of a substantially cheaper version (Cystagon) of the exact same drug [where the] only difference is dosing frequency."

Also mentioned is UnitedHealth's supposed move to put Procysbi on 2014's excluded drug list.

Summing up, Favus has a question for RPTP investors: "At what price would QCOR trade if a generic version of Acthar Gel was available at a 96% discount?" The firm calls the similarities between RPTP and QCOR "striking."
