What will happen in the study?
This is a multicenter, phase I dose-escalation study followed by a phase II study.
Patients receive oral crizotinib twice daily on days 1-28. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity.
Plasma and whole blood samples are collected for pharmacokinetic and pharmacogenomic analysis. Tumor tissue (from patients with neuroblastoma) and bone marrow and/or peripheral blood (from patients with anaplastic large cell lymphoma) samples are collected for further correlative laboratory studies.
After completion of study treatment, patients are followed up periodically.
