>Yet neither TEVA nor Amphastar, with the same need for data on immunogenicity, so far as we know have NOT received a not approvable designation.<

According to WPI’s CEO, they did (#msg-24636279).

MNTA: Perhaps the FDA has not completed their review of each respective application for Teva/Amphastar. Regardless, immunogenicity will be a concern for both of those companies.
MNTA received a "not approvable" letter because the FDA didn't want (apparently) to reject the app outright; additionally, an "approvable letter" mechanism isn't in place for ANDA's.

I probably misspoke. I should have said submit the immunogenicity data not refile.

On the competition, it's actually not material to teva stock so they dont need to disclose anything and amphastar is private, I bet they weren't happy when wpi publicly discussed it.
