Supplementary Fig. 1 Study design protocol, showing the original and amended protocols a In Level 2a and 3, vinorelbine dose omission allowed for absolute neutrophil count <1500/mm3. Compared with dose level 2, dose level 3 allowed dose modifications as used in a phase III clinical trial of this combination [19] (dose omission for vinorelbine and dose reduction for afatinib).
