Thanks, Breanna. Good morning, everybody. This morning we announced that during our preplanned scheduled mid-cycle communication meeting held last week with the FDA, the agency requested additional clinical data for use in the efficacy analysis for both the 500 milligram and 625 milligram b.i.d. dose patient groups for rociletinib.

Weve prepared this information and will provide it in a major amendment to the FDA by the close of business today. We remain of course confident in rociletinib and its potential to treat patients with mutant EGFR T790M positive lung cancer and we will continue to work diligently with the FDA on our NDA submission.

In the mid-cycle communication meeting, the FDA emphasized that its efficacy analysis would focus solely on confirmed responses. The NDA submission contained immature data sets based on both unconfirmed response rates and confirmed response rates. These data sets were updated in the 90-day efficacy update we submitted to the FDA at the end of October.

As rociletinib clinical trials were rapidly enrolling, we presented interim data publicly and at medical meetings and these data therefore included a data set based primarily on unconfirmed responses. This was also true of our breakthrough therapy destination submission and our NDA submission; both immature confirmed and unconfirmed response analyses were submitted.

As the efficacy data had matured, the number of patients with an unconfirmed response who converted to a confirmed response was lower than expected. In the intent-to-treat analysis of the 79 patients in the 500 milligrams dose group, the current confirmed response rate is 28% and in the 170 patients in the 625 milligram dose group, its 34%. In both cases we have a duration of response of nine months.

The most frequent reasons that patients responses were not confirmed in a subsequent scan were due to progression, often due to brain metastasis, and due to subsequent scans not demonstrating tumor shrinkage greater than 30%. The majority of these patients stayed on...
