Dear HS,

❝ Can be very tough. Early partial AUCs are always highly variable. No scaling for EMA… See this one (slides 51–56). Besides the CV, have a look at the PEs of the two studies of slide 54. All formulations got approval as hybrids (MR vs. IR + clinical studies). Interchangeability: ¡nada!


Patents are not assessed to any degree resembling the assessment at NCAs. I meant to say that in spite of all the trouble with variability and SPC's and food and all the other fancy stuff that matters in the PK-approval-agency-world, originator companies could try and patent the cuttoff or profile. If they were successful it would be game over for the generic industry for any MR covered by the patent regardless of other patent expiry:
First approval of one MR or other, then a year or two before generic competition is possible do a line extension (which does not necessarily require equivalence) to a formulation principle which is patented and which entails a cutoff or other such thingy, then cancel the MA for the original formulation and enjoy another x effective years of protection.

Best regards,
EM.
