Study design details

Main study objective

To evaluate the late-effects associated with the central and peripheral nervous system, growth and endocrine development, auditory, visual, hepatic, renal, lower urinary tract, cardiac, respiratory, skeletal, second and secondary malignancies in patients who received Unituxin for neuroblastoma and remain event-free for at least 5 years since the start of Unituxin immunotherapy.

Outcomes

The late effects associated with the relevant systems and second/secondary malignancies will be analysed in the Safety Set of patients by comparing the characteristics at 12 months to 5 years tothe characteristics at baseline using descriptive statistics. Event-free survival (EFS) and Overall Survival (OS) will be assessed every 6 months for up to 5 years following treatment. EFS will be calculated as the time from start of Unituxin until the first occurrence of the events of relapse, PD, secondary malignancy, or death. If no event occurs, the date of last contact will be used. OS will be calculated as the time from start Unituxin until death.

Data analysis plan

All analyses will be performed using SAS for Windows statistical software using validated implementations of each application or SAS custom programming. The data from all centres will be combined, so that an adequate number of patients will be available for analyses. Summary tabulations will be presented that will display the number ofobservations, mean, standard deviation, median, minimum and maximum for continuous variables, and the number and percentage per category for categorical or ordered categorical data. In addition, two sided 95% confidence intervals will be calculated for all outcomes when possible.
