Description
This Phase I study of crizotinib involved a cohort of pediatric neuroblastoma patients between ages 12 months and 22 years. In 11 patients with characterized ALK mutations, 4 had R1275Q mutations, and two of these were germline mutations. Of these 2 germline patients, 1 showed stable disease (SD) and 1 complete response (CR). In contrast, in the 7 characterized patients with ALK mutations that were not R1275Q, 6 showed PD and 1 SD. The authors conclude this finding is promising and merits further study.
