Brief Summary:
Children with a neuroblastoma diagnose and central nervous system (CNS)/leptomeningeal metastases will be given up to 2 rounds of intracerebroventricular treatment with a radiolabelled monoclonal antibody, 131I-burtomab to evaluate efficacy and safety

Condition or disease Intervention/treatment Phase
Neuroblastoma CNS Metastases Leptomeningeal Metastases Biological: 131I-burtomab Phase 2 Phase 3

Detailed Description:

One 131I-burtomab treatment cycle takes 5 weeks and includes a dosimetry dose, a treatment dose, an observation period and post-treatment evaluations.

  • A dosimetry dose (2mCi) of 131I-burtomab is administered during week 1 followed by blood/cerebral spinal fluid (CSF) samples and whole-body scintigraphy at predefined intervals during the following 48 hours after treatment.
  • A therapeutic dose (50mCi) of 131I-burtomab is administered during week 2 followed by a 3-week observation period that includes a repeated MRI, CSF cytology, and safety monitoring.
  • A second treatment cycle of 131I-burtomab is administered during week 6 if there is no objective disease progression week 5 after the first injection, and the participant is presenting without unexpected and clinical significant Grade 4 toxicity. For participants with ongoing Grade 3 toxicity a second doing cycle will take place according to the discretion of the investigator

Participants can be treated in an outpatient setting or may be admitted as inpatients for both the dosimetry and the therapeutic injections.

Participants completing at least one treatment period will first enter a follow-up period through week 26 and thereafter the long-term follow-up where patients will be evaluated for up to 3 years post-131I-burtomab treatment where after the trial is ended

Participants will be monitored for adverse events during and after 131I-burtomab injection and will have pre- and post-treatment clinical assessments including neurologic examination, hematology and serum chemistry, blood and CSF cultures, endocrinology assessments, CSF analysis, and, pre- and post 131I-burtomab performance testing. Performance testing will be performed at trial baseline, at week 26 and every 6 months during trial period.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 32 participants
Intervention Model: Single Group Assignment
Intervention Model Description: Patients will receive up to two cycles of intracerebroventricular 131I-burtomab. Safety and efficacy will be investigated with short-term follow-up at 26 weeks after treatment and with long-term follow-up for up to 3 years following treatment.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Multicenter Phase 2/3 Trial of the Efficacy and Safety of Intracerebroventricular Radioimmunotherapy Using 131I-burtomab for Neuroblastoma Central Nervous System/Leptomeningeal Metastases

Arm Intervention/treatment
Experimental: 131I-burtomab

One treatment cycle of 131I-burtomab consists of 2 doses; 2mCi at week 1 and 50mCi at week 2). First cycle is initiated right after confirmation of eligibility at week 1. At week 6 the participant will be evaluated for safety and if eligible, receive a second cycle of 131I-burtomab.

Secondary efficacy endpoints will be evaluated at week 26 and primary efficacy endpoint will be evaluated at week 156.

Biological: 131I-burtomab
