Naxitamab Added to Induction for Newly Diagnosed High-Risk Neuroblastoma
93 patients around the world
Available in United States, Brazil
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.
All subjects will be followed for disease response, event free survival, overall survival
and toxicity. Extent of disease will be measured and assessed for changes throughout the
course of the study. All efficacy analyses will be performed on the evaluable population
which will consist of all enrolled subjects (subjects who initiate treatment with
naxitamab in combination with GM-CSF plus standard induction therapy) and who have
measurable disease at baseline.
The initial chemotherapy Induction regimen will utilize sequential administration of 5
cycles of multi-agent chemotherapy. Naxitamab will be added to all 5 Induction cycles.
Stem cell mobilization and collection will occur after the 2nd cycle of induction.
Surgical resection of the primary tumor will ideally occur after the 4th cycle of
Induction but may be delayed until after the 5th cycle of Induction if medically
necessary.
Disease status evaluations will occur at the following time points: (1) pre-treatment,
(2) post Cycle 2 Induction (3) Prior to surgical resection (if performed), (4) End of
Induction (which includes surgery and 5 cycles of chemotherapy), and (5) End of
Additional/Salvage Therapy as needed.
The current standard of care for high-risk neuroblastoma involves 5-7 cycles of induction
chemotherapy with surgical removal of the tumor after 4-5 cycles of chemotherapy,
followed by high-dose chemotherapy plus autologous stem cell transplant, then radiation
to the primary tumor bed, followed by anti-GD2 immunotherapy and cis retinoic acid. This
results in a less than 60% disease free survival for high-risk NB, a survival rate that
still greatly needs improvement. Two areas in which improvements can be made include: 1)
to improve response rate to induction chemotherapy and 2) to improve EFS by improving
maintenance therapy to prevent relapse.
We hypothesize that the addition of anti-GD2 therapy to induction chemotherapy will
result in improved end of induction responses and improved survival.

- 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.Subjects with newly diagnosed neuroblastoma with INRGSS Stage M disease with either of the following features.MYCN amplification (> 4-fold increase in MYCN signals as compared to reference signals), regardless of additional biologic features; OR.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.Age > 547 days of age regardless of biologic features.Subjects with newly diagnosed neuroblastoma with INRGSS Stage MS disease with either of the following.MYCN amplification (> 4-fold increase in MYCN signals as compared to reference signals); OR.365 days to ≥ 547 days (18 months) of age without MYCN amplification, but unfavorable biologic features such as unfavorable histology (INPC) or diploid tumor (DNA index=1) or SCA as above.Subjects with newly diagnosed neuroblastoma INRGSS Stage L2 disease with either of the following.MYCN amplification (> 4-fold increase in MYCN signals as compared to reference signals); OR.18 months to <5 years of age without MYCN amplification, but with unfavorable histology (INPC); OR.≥5 years of age without MYCN amplification, but with undifferentiated or poorly differentiated INPC Subjects with newly diagnosed neuroblastoma INRGSS Stage L1 disease that is incompletely resected with MYCN amplification.Subjects > 547 days of age initially diagnosed with INRGSS Stage L1, L2 or MS disease who progressed to Stage M without prior chemotherapy may enroll within 4 weeks of progression to Stage M.Subjects ≥ 365 days of age initially diagnosed with MYCN amplified INRGSS Stage L1 disease who progress to Stage M without systemic therapy may enroll within 4 weeks of progression to Stage M.Subjects must be age ≤ 21 years at initial diagnosis.Subjects must be >12 months of age at enrollment.Adequate cardiac function defined as.Shortening fraction of ≥ 27% by echocardiogram, or.Ejection fraction of ≥ 50% by radionuclide evaluation or echocardiogram.Adequate liver function must be demonstrated, defined as.Total bilirubin ≤ 1.5 x upper limit of normal (ULN) for age AND.ALT (SGPT) < 5 x upper limit of normal (ULN) for age.Subjects must have adequate renal function defined as.For subjects < 17 years old: estimated Glomerular Filtration rate (eGFR) as calculated from the Bedside Schwartz equation (in units of mL/min/1.73 m2) or via radioisotope GFR of ≥ 70 mL/min/1.73 m2. The Bedside Schwartz equation is: [(0.413) X (Height in cm)] / SCr.For subjects ≥17 years old: estimated Glomerular Filtration rate (eGFR) as calculated from the Cockcroft and Gault formula (in units of mL/min/1.73 m2) or via radioisotope GFR of ≥ 70 mL/min/1.73 m2. The Cockcroft and Gault formula is: [(140-age) x (Wt in kg) x (0.85 if female)] / (72 x SCr).OR a 24 hour urine Creatinine clearance ≥ 70 mL/min/1.73 m2.A negative serum pregnancy test is required for subjects of childbearing potential (≥13 years of age or after onset of menses).Both male and female post-pubertal study subjects must be willing to use a highly effective contraceptive method (i.e., achieves a failure rate of <1% per year when used consistently and correctly) from the time of informed consent (and assent, as applicable) until 6 months after study treatment discontinuation. Such methods include: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner, sexual abstinence.Informed Consent: All subjects and/or legal guardians must sign informed written consent. Assent, when appropriate, will be obtained according to institutional guidelines and applicable local regulations.

In addition, room air pulse oximetry < 94% and/or abnormal pulmonary function tests if these assessments are clinically indicated.Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study.).Subjects receiving any investigational drug concurrently.Subjects with any other medical condition, including but not limited to malabsorption syndromes, mental illness or substance abuse, deemed by the Investigator to be likely to interfere with the interpretation of the results or which would interfere with a subject's ability to sign or the legal guardian's ability to sign the informed consent, and subject's ability to cooperate and participate in the study.Subjects with a significant intercurrent illness (any ongoing serious medical problem unrelated to cancer or its treatment) that is not covered by the detailed exclusion criteria and that is expected to interfere with the action of investigational medicinal products (IMPs) or to significantly increase the severity of the toxicities experienced from trial treatment.
