"With genomics, and pharmacogenomics, and all the other aspects of the cancers, we have to think of a different way than the randomized trial," said Patrick Loehrer, interim director of Indiana University's cancer center and a member of FDA's Oncology Drugs Advisory Committee.

Although the decision to withdraw its accelerated approval NDA doesn't preclude the company from filing an entirely new NDA for Iressa in NSCLC patients with EGFR mutations, as it has done in several European countries, AstraZeneca has decided not to try to relaunch Iressa with a PGx strategy in the US.
