Tuck,

Similar questions I asked myself. We do not know Iressa PIII tox profile for stage IIIb/IV NSCLC. Side effect profile and IP incidence was from ~200 pts (combination of US and Japan PII trial).

Iressa compassionate use count ~10000 pts and so far no word on IP incidence. Also for bit less sick NSCLC (two PIII trials) it was not reported higher IP incidence.

Regards the mechanism, so far I can not connect EGF and IP incidence. It can be related to anti-EGF in general, anti-EGF small molecule or Iressa itself????

However, I do believe that this increase in IP incidence and 13 death are in part related to higher Iressa daily dose, which can explain difference from trials and real world.

ABGX claim that they did not observed pneumonia in their PI trials, and probably ongoing PII trials. This does not guaranty that they will not have the some problems. Nonetheless, market is acting like this are FACTS (for ABGX and OSIP).
