About this study
Official title: A Multicenter Phase 2/3 Trial of the Efficacy and Safety of Intracerebroventricular Radioimmunotherapy Using 131I-omburtamab for Neuroblastoma Central Nervous System/Leptomeningeal Metastases
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-omburtamab to evaluate efficacy and safety
Read the detailed description
One 131I-omburtamab treatment cycle takes 4 weeks and includes a treatment dose, and an observation period and post-treatment evaluations.
One 131I-omburtamab treatment cycle for Japan only takes 5 weeks and includes a dosimetry dose (2mCi) of 131I-omburtamab 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-omburtamab is administered during week 1 (week 2 for Japan) followed by a 3-week observation period that includes a repeated MRI, CSF cytology, and safety monitoring.
- A second treatment cycle of 131I-omburtamab is administered during week 5 (week 6 for Japan) 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-omburtamab treatment where after the trial is ended
Participants will be monitored for adverse events during and after 131I-omburtamab 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-omburtamab performance testing. Performance testing will be performed at trial baseline, at week 26 and every 6 months during trial period.
In case the patient has a subsequent relapse in the CNS/LM after 131I-omburtamab therapy during the follow-up period, re-treatment to target minimal residual disease can be considered and allowed.

| Study group | Role | What they receive |
|---|---|---|
| 131I-omburtamab | Experimental | One treatment cycle of 131I-omburtamab consists of one dosimetry dose (2 mCi ) (for subjects enrolled on Version 1-7 of Protocol 101) and one treatment dose (50 mCi) for up to 2 cycles of length 5 weeks (for subjects enrolled on Version 1-7 of Protocol 101) or 4 weeks (for subject enrolled after Version 7 of Protocol 101). For Japan only, the first cycle consisted of one dosimetry dose (2 mCi ) week 1 one treatment dose (50 mCi) week 2. If eligible a second cycle of 50 mCi 131I-omburtamab was given at week 6. For subjects below 3 and 1 years of age, the treatment dose was reduced by 33% and 50%, respectively. Receives: Biological: 131I-omburtamab |

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing 131I-omburtamab in people with Neuroblastoma and CNS Metastases, run by Y-mAbs Therapeutics at 8 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 13 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States, Denmark, Japan, Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 13 Feb 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall Survival Rate (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03275402, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2024.
