Brief Summary:

RATIONALE: CEP-701 may stop the growth of tumor cells by blocking the enzymes necessary for their growth.

PURPOSE: This phase I trial is studying the side effects and best dose of CEP-701 in treating young patients with recurrent or refractory high-risk neuroblastoma.

Condition or disease Intervention/treatment Phase
Neuroblastoma Drug: lestaurtinib Phase 1

Detailed Description:



  • Determine the maximum tolerated dose of CEP-701 in pediatric patients with recurrent or refractory high-risk neuroblastoma.
  • Determine the dose-limiting toxicity of this drug in these patients.
  • Determine the pharmacokinetic behavior of this drug in these patients.


  • Determine the degree of TrkB tyrosine kinase inhibition activity present in the serum of patients treated with this drug.
  • Correlate the degree of TrkB tyrosine kinase inhibition activity in these patients with dose level, pharmacokinetics, and antitumor activity data of this drug.
  • Determine the antitumor activity of this drug in these patients.

OUTLINE: This is an open-label, dose-escalation, multicenter study.

Patients receive oral CEP-701 twice daily* on days 1-5, 8-12, 15-19, and 22-26. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

NOTE: *On day 1 of course 1 only, patients receive oral CEP-701 once instead of twice.

Cohorts of 3-6 patients receive escalating doses of CEP-701 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, the dose level is expanded up to 9 patients.

PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.

MedlinePlus related topics: Neuroblastoma

Intervention Details:
  • Drug: lestaurtinib
    Given orally twice daily x 5 consecutive days followed by a two day rest. 28 days = 1 treatment course. Courses repeated indefinitely without gap provided patient has recovered course from toxicities and no DLTs. Dose level assigned according to the planned dose escalation schedule.
    Other Name: CEP-701

Primary Outcome Measures :
  1. To determine the maximum tolerated dose (MTD) of CEP-701 given on a twice daily chronic administration schedule (two days on , two days off) to children with high risk relapsed or residual neuroblastoma. [ Time Frame: Within 28 days of treatment at each dose level. ]
  2. To determine dose limiting toxicities (DLTs) of CEP-701 given on this schedule [ Time Frame: Within first 28 days of therapy. ]
  3. To characterize the pharmacokinetic (PK) behavior of CEP-701 in children with residual or refractory high-risk neuroblastoma. [ Time Frame: Days 1,5 and 26 of first course only. ]
    Participation in PK studies is voluntary and not a requirement for study entry.

Secondary Outcome Measures :
  1. To determine the degree of TrkB tyrosine kinase inhibition activity present in the serum of patients treated with CEP-701, and correlate these findings with dose level, pharmacokinetic and anti-tumor activity data. [ Time Frame: Days 1,5 and 26 of first course only. ]
  2. To define the antitumor activity of CEP-701, within the confines of a Phase I study. [ Time Frame: Evaluation at end of courses 1, 2, 4 and then every 4 courses until patient goes off therapy. ]
