Study Description
Brief Summary:
This phase II trial is studying how well ABT-751 works in treating children with neuroblastoma that has relapsed or not responded to previous treatment. Drugs used in chemotherapy, such as ABT-751, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

Condition or disease Intervention/treatment Phase
Disseminated Neuroblastoma Recurrent Neuroblastoma Drug: ABT-751 Procedure: quality-of-life assessment Phase 2

Detailed Description:


I. Compare the time to disease progression in children with refractory or relapsed neuroblastoma treated with ABT-751 vs historical controls.


I. Determine the objective response rate in patients with measurable disease treatment with this drug.

II. Determine whether ABT-751 improves quality of life of these patients. III. Determine the toxicity of ABT-751. IV. Determine the pharmacokinetic profile of ABT-751 in these patients.


Patients receive oral ABT-751 once daily on days 1-7. Treatment repeats every 21 days for 52 courses in the absence of disease progression or unacceptable toxicity.

Blood is collected periodically during course 1 for pharmacokinetic studies. Quality of life is assessed at baseline and prior to each course of treatment.

After completion of study treatment, patients are followed up for up to 5.1 years.

Outcome Measures

Primary Outcome Measures :
  1. Median Time to Progression as Assessed by Response Evaluation Criteria in Solid Tumors [ Time Frame: From time to enrollment to death due to any cause, assessed up to 5.1 years ]
    Median time to progression observed on ABT-751, along with 95% confidence intervals.

  2. 1-year Progression-free Survival [ Time Frame: From the day of enrollment to the date of disease progression/recurrence , or the date of death (all causes of mortality) if disease progression/recurrence is not reached, assessed up to 1 yr. Pts were to be followed for 5 yrs after completion of therapy ]
    PFS probabilities calculated using the Kaplan-Meier method, along 95% confidence intervals, separately for each stratum.

Secondary Outcome Measures :
  1. Objective Response Rate [ Time Frame: Duration of protocol therapy ]
    The proportion of patients who are responders will be tabulated, including a 95% confidence interval on the proportion.

  2. Quality of Life Measured by PedsQL™ Generic Core Scale Version 4.0 [ Time Frame: 3 weeks ]
    For each of the items within a Dimension, the QOL score will be reverse linearly transformed to a 0-100 percentage point scale (0=100, 1=75, 2=50, 3=25, 4=0), and the average of all items within a Dimension will be calculated. This results in 4 definitive scores at each timepoint. The average of all 23 items will be the Total Score at a given timepoint; and, 2) the repeated measures of performance status (Karnofsky score for patients > 16 years of age and Lansky score for patients ≤ 16 years of age).

  3. Toxicity as Assessed by Common Terminology Criteria for Adverse Events Version 3.0 [ Time Frame: yearsFrom enrollment until 30 days after the end of protocol therapy ]
    Toxicity will be tabulated by grade (overall and by course).
