Conditions

Outcome Measures

Primary Outcomes (1)

  • Overall Response Rate (ORR)

    The proportion of patients obtaining a centrally assessed complete response (CR) or partial response (PR) according to the International Neuroblastoma Response Criteria (INRC)

    84 days

Study Arms (1)

Naxitamab and GM-CSF in combination with irinotecan and temozolomide

EXPERIMENTAL

A treatment cycle is 21 days. The patients will receive irinotecan 50 mg/m2/day IV and temozolomide 100 mg/m2/day orally (both on Days 1-5) in combination with naxitamab 2.25 mg/kg/day IV (Days 2, 4, 8 and 10) (total 9 mg/kg per cycle), and GM-CSF 250 ug/m2/day sc, (Days 6-10). Patients will receive up to 18 IT cycles after enrollment. Naxitamab and GM-CSF will be given for at least 8 cycles.

Drug: Naxitamab and GM-CSF in combination with irinotecan and temozolomide

Interventions

* Irinotecan, solution for infusion (20 mg/mL) * Temozolomide, capsules (5 mg, 20 mg and 100 mg) * The humanized immunoglobulin isotype G (IgG1) monoclonal antibody (mAb) naxitamab, solution for infusion (4 mg/mL) * Sargramostim (GM-CSF), lyophilized 250 µg single use vial (250 µg/vial)

Naxitamab and GM-CSF in combination with irinotecan and temozolomide

Eligibility Criteria

Age12 Months+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Neuroblastoma (NB)
  • Documented high-risk disease
  • Receipt of Standard of Care (SoC) frontline induction/consolidation therapy (including surgery, chemotherapy, ASCT, MIBG, radiotherapy, immunotherapy, or retinoids)
  • Active disease despite previous aggressive multi-drug chemotherapy, defined as one of the following:
  • verified first progression during multi-drug frontline treatment or
  • verified first episode of relapse, defined as recurrence after response to frontline treatment, or
  • verified first designation of refractory disease, defined as persistent metastatic disease (SD or minor response by INRC and MIBG curie score ≥3) detected at conclusion of at least 4 cycles of multi-drug induction chemotherapy on or according to a high-risk NB treatment protocol as defined above
  • The patients must have one of the following (locally assessed) obtained within 3 weeks prior to enrollment and at least 10 calendar days after end of any prior anti-cancer treatment:
  • Measurable tumor on CT/MRI scan that is MIBG-avid or demonstrates increased FDG uptake on PET scan
  • MIBG (Metaiodobenzylguanidine) scan with positive uptake at a minimum of one site. This site must represent disease recurrence after completion of therapy, progressive disease on therapy, or refractory disease during induction
  • Age ≥ 12 months at enrollment
  • Written informed consent

You may not qualify if:

  • Myelodysplastic syndrome or any malignancy other than NB
  • Any systemic anti-cancer therapy within 3 weeks
  • Autologous stem cell transplant (ASCT) within 6 weeks prior to enrollment or ongoing toxicity due to the stem cell transplant at the discretion of the investigator
  • Therapeutic 131I-MIBG within 6 weeks prior to enrollment
  • Radiotherapy (RT) within 4 weeks prior to enrollment at any lesion site that will be identified as a target lesion to measure tumor response
  • Prior treatment with anti-GD2 if the patient experienced Progressive Disease (PD) while on anti-GD2 treatment
  • Receipt of second line chemotherapy after designation of primary refractory disease or first relapse or PD
  • NB in Bone Marrow (BM) only
  • NB in the Central Nervous System (CNS) or leptomeningeal disease within 6 months prior to enrollment
  • Performance status of \< 50% as per the Lansky scale (patients less than 16 years of age) or Karnofsky scale (for patients aged 16 years or older)
  • Life expectancy of less than 6 months
  • Left ventricular ejection fraction \< 50% by echocardiography
  • Inadequate pulmonary function
  • Diarrhea Grade ≥ 2
  • Treatment with long-acting myeloid growth factor within 14 days or short-acting myeloid growth factor within 7 days prior to first dose of GM-CSF
  • +20 more criteria
