Goldman Sachs just issued a report saying that the non-approval MNTA received in Nov 2007 relating to Lovenox immunogenicity was a Minor Deficiency letter. This is contrary to my understanding of what happened, but I thought it was worth mentioning.
i'm not so sure i agree clark. if you recall amphastar stated in their lawsuit they got their level of impurity down to very low level but still faced immunogenicity hurdle. i stated on this board that i think teva likely did too, but that the more significant immunogenicity hurdle was that related to the innate immunogenicity of the product itself (e.g. Abs to PD4)
