2 FIGURE 1 Waterfall Plot. (A) The best calculated responses based on measurable lesions for evaluable patients, N=51. Here, 50 evaluable patients represented as one patient had unequivocal progression of a nontarget pleural effusion that obscured measurement of underlying target lesions. (B) The best calculated responses based on measurable lesions for all patients with EGFR-mutant tumors, N=14. *Patients with unconfirmed partial response. EGFR, endothelial growth factor receptor.

3 FIGURE 2 Kaplan-Meier curves for outcomes. (A) Progression-free survival for 51 evaluable patients, depending upon whether a sensitizing mutation was present or not in the tumor sample. (B) Overall survival for entire cohort of 55 patients, depending upon whether sensitizing mutation was present or not in the tumor sample.

4 FIGURE 3 Representative XL647 plasma concentration versus time profiles. (A) Patients on the intermittent 5+9 dosing schedule. (B) Patients on the daily schedule. Actual data (open circle) and predicted data (solid line) are plotted together.
