Time to progression is defined as the time in months between the first treatment date until the date of radiographic disease progression. For participants who enter the LTFU Phase, all MRI assessments in both the Treatment Phase and LTFU Phase will be used to determine time to progression. Participants without radiographic disease progression will have their results censored to their most recent adequate (i.e. evaluable) tumor assessment date.","dispersionType":"95% Confidence Interval","groups":[{"description":"Patients aged 2 to 17 years old at the time of informed consent.
