The 3-month delay was expected because PFE said so on its 2Q12 CC in July.
Tofacitinib has an 85% chance of approval on the first review cycle, IMO. I concur with genisi’s assessment in #msg-75539892—i.e. the unmet medical need will trump the ambiguity wrt Tofacitinib’s results in the (non-primary endpoint) of radiographic progression relative to the control arm.
I expect the FDA to grant Tofacitinib a third-line label; if the FDA grants a second-line label, it will be a pretty big win for PFE.
