Clinical trial: Crizotinib in Treating Younger Patients With Relapsed or Refractory Solid Tumors or Anaplastic Large Cell Lymphoma

Summary: This phase I/II trial the studies side effects and best dose of crizotinib and to see how well it works in treating young patients with solid tumors or anaplastic large cell lymphoma that has returned after a period of improvement or does not respond to treatment. Crizotinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. (Phase I completed 2/15/13)

Detailed description: PRIMARY OBJECTIVES:
  I. To estimate the maximum tolerated dose (MTD) and recommend a Phase 2 dose of PF-02341066 (crizotinib) administered orally twice daily to children with relapsed/refractory solid tumors and anaplastic large cell lymphoma (ALCL). (completed 2/15/13) II. To define and describe the toxicities of PF-02341066 administered on this schedule.
  III. To characterize the pharmacokinetics of PF-02341066 in children with refractory cancer.
  SECONDARY OBJECTIVES:
  I. To preliminarily define the anti-tumor activity of PF-02341066 within the confines of a Phase 1 study. (completed 2/15/13) II. To obtain initial Phase 2 data on the anti-tumor activity of PF-02341066 in children with relapsed/refractory neuroblastoma and ALCL.
  III. To preliminarily examine the relationship between anaplastic lymphoma kinase (ALK) status (e.g, the presence of a mutation, duplication, amplification, and/or translocation) in patients with neuroblastoma (NB) or ALCL and response to PF-02341066.
  IV. To preliminarily examine the relationship between minimal residual disease (MRD) status and clinical response to PF-02341066 in patients with ALCL.
  V. To use a questionnaire to gather preliminary information on the palatability of the oral solution formulation of PF-02341066.
  VI. To evaluate for potential alterations in bone growth in pediatric patients.
  OUTLINE: This is a phase I dose-escalation study (completed 2/15/13) followed by a phase II study.
  Patients receive crizotinib orally (PO) twice daily (BID) on days 1-28. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up periodically.
