Figure 1 Efficacy outcomes (intent-to-treat population): progression-free survival (PFS) (A) and PFS subgroup analysis (B). Medians of PFS are Kaplan-Meier estimates. Hazard ratios were estimated by Cox regression. CI, confidence interval; CNS, central nervous system; ECOG, Eastern Cooperative Oncology Group; IRC, independent review committee; NE, not estimable.

Figure 2 Investigator-assessed best overall response (intent-to-treat population): patients treated with alectinib (A) and patients treated with crizotinib (B). CR, complete response; NE, not estimable; PD, progressive disease; PR, partial response.

Figure 4 Objective response rate (ORR) (investigator [INV]-confirmed) by echinoderm microtubule-associated protein-like 4 gene (EML4)–anaplastic lymphoma kinase gene (ALK) fusion variant in both the tissue and plasma biomarker-evaluable population subgroups. *Pearson's chi-square test comparing all three variants. CR, complete response; PD, progressive disease; PR, partial response; V, variant.
