Naxitamab Added to Induction for Newly Diagnosed High-Risk Neuroblastoma
What this study is about
This is a forward-looking, conducted at multiple hospitals clinical trial in subjects with newly diagnosed high-risk neuroblastoma to evaluate the effectiveness and safety of administering naxitamab with standard induction therapy. The initial chemotherapy will include 5 cycles of multi-agent chemotherapy. Naxitamab will be added to all 5 Induction cycles.
View original scientific description
This is a prospective, multicenter clinical trial in subjects with newly diagnosed high-risk neuroblastoma to evaluate the efficacy and safety of administering naxitamab with standard induction therapy. The initial chemotherapy will include 5 cycles of multi-agent chemotherapy. Naxitamab will be added to all 5 Induction cycles. We hypothesize that the addition of anti-GD2 therapy to induction chemotherapy will result in improved end of induction responses and improved survival.
Interventions
DRUG
Naxitamab
Naxitamab is a humanized (IgG1) anti-GD2 (hu3F8) monoclonal antibody for the treatment of neuroblastoma, osteosarcoma and other GD2-positive cancers. Naxitamab was granted accelerated approval by the FDA in 2020 as treatment (in combination with granulocyte-macrophage colony-stimulating factor - GM-CSF) for pediatric patients at least one year of age and adult patients with relapsed or refractory high-risk neuroblastoma in the bone or bone marrow demonstrating a partial response, minor response, or stable disease to prior therapy
Primary outcome measures
Number of participants with Complete Response (CR) rate per 1993 INRC guidelines
Time frame: 6 to 12 months
Measured by the presence of radiologically assessable disease by cross-sectional computed tomography (CT) or Magnetic resonance imaging (MRI) imaging and/or by metaiodobenzylguanidine (MIBG) or positron emission tomography (PET) scans and bone marrow (BM) response for subjects with newly-diagnosed high-risk neuroblastoma according to the 1993 International Neuroblastoma Response Criteria (INRC) and compare to relevant historical controls.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Diagnosis: Subjects must have a diagnosis of neuroblastoma or ganglioneuroblastoma (nodular or intermixed) verified by histology or demonstration of clumps of tumor cells in bone marrow with elevated urinary catecholamine metabolites. Subjects with the following disease stages at diagnosis are eligible, if they meet the other specified criteria: 2. Subjects with newly diagnosed neuroblastoma with INRGSS Stage M disease with either of the following features: 1. MYCN amplification (\> 4-fold increase in MYCN signals as compared to reference signals), regardless of additional biologic features; OR 2. 365 days to ≥ 547 days of age without MYCN amplification, but unfavorable biologic features such as unfavorable histology (INPC) or diploid tumor (DNA index=1) or the presence of any segmental chromosome aberration (SCA) (somatic copy number loss at 1p, 3p, 4p, or 11q or somatic copy number gain at 1q, 2p, or 17q); OR 3. Age \> 547 days of age regardless of b

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
