Combination Therapy of Antibody Hu3F8 With Granulocyte- Macrophage Colony Stimulating Factor (GM-CSF) in Patients With Relapsed/Refractory High-Risk Neuroblastoma

The purpose of this study is to find out if an antibody called Humanized 3F8 (Hu3F8) combined with granulocyte- macrophage colony stimulating factor (GM-CSF) is safe for treating neuroblastoma.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Diagnosis of NB as defined by a) histopathology (confirmed by the MSKCC Department of Pathology), or b) BM metastases or MIBG-avid lesion(s) plus high urine catecholamine levels.
  • Patients must have high-risk NB (including MYCNamplified stage 2/3/4/4S of any age and MYCN-nonamplified stage 4 in patients greater than 18 months of age) AND:
  • Phase I: Patients must have refractory or relapsed NB, resistant to standard therapy*.

*For NB, standard therapy includes intensive induction chemotherapy, followed by a variety of consolidation or salvage therapies, depending on response.

  • Phase II: Patients must have primary or secondary refractory disease in BM, defined as morphologic evidence of NB in BM and/or abnormal 123I-MIBG uptake in osteomedullary sites, OR patients patients in ≥ 2nd CR patients are in ≥2nd CR
  • Patients must be older than 1 year of age.
  • Prior treatment with murine and humanized 3F8 is allowed. Patients with prior m3F8, hu3F8, ch14.18 or hu14.18 treatment must have a negative HAHA antibody titer. Human anti-mouse antibody (HAMA) positivity is allowed.
  • White blood cell count ≥1000/ul (phase I only)
  • Absolute neutrophil count ≥500/ul (phase I only)
  • Absolute lymphocyte count ≥500/ul (phase I only)
  • Platelet count ≥25,000/ul (phase I only)
  • No chemotherapy or immunotherapy for a minimum of three weeks prior to start of hu3F8
  • Women of child-bearing potential must be willing to practice an effective method of birth control while on treatment
  • Signed informed consent indicating awareness of the investigational nature of this program.

Exclusion criteria

  • Existing major organ dysfunction > grade 2, with the exception of hearing loss and hematologic toxicity (defined as suppression of all subtypes of WBCs, RBCs, and platelets).
  • Active life-threatening infection.
  • Pregnant women or women who are breast-feeding.
  • Inability to comply with protocol requirements, including PK studies and genetic studies (phase I only)
  • History of allergy to mouse proteins.
  • Positive human anti-hu3F8 antibody (HAHA) titer

Treatment and study plan

Hu3F8 With GM-CSF

Biological

Ph I: 1 cycle consists of treatment with hu3F8 for 3 days (day 1, 3 & 5). GM-CSF starts 5 days in advance of each hu3F8 cycle at 250 mcg/m^2/day (day -4 to day 0), & at 500 mcg/m^2/day x 5 days (day 1 to day 5). Hu3F8 cycles are 5 days. Ph II pts may receive treatment on a modified schedule of 3 doses of IV hu3F8 over a maximum of 10 days, as needed. With modified schedules of hu3F8, GM-CSF will be administered at 250 mcg/m2/day x5 days before the 1st dose of hu3F8, as with the standard schedule, but then GM-CSF at 500 mcg/m2/day will be administered on day of the 1st dose of hu3F8, on the day before and on the day of the 2nd dose of hu3F8, and on the day before and on the day of the 3rd dose of hu3F8. Cycles are repeated at 2-4 week intervals between 1st days of hu3F8, through 4 cycles. Pts who complete 4 cycles of treatment w/o complications or disease progression have the option of continuing treatment for up to 24 months from their 1st dose of hu3F8.

Primary outcomes

  1. maximum tolerated dosage

    Time frame: 1 year

    hu3F8 when combined with GM-CSF. DLT is defined after 1 cycle. Seventeen dosage levels of hu3F8 will be tested with three to six patients at each dosage level.

  2. assess the toxicity

    Time frame: 1 year

    of the humanized anti GD2 antibody hu3F8 when combined with Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) in patients with high risk neuroblastoma. All observed adverse events, regardless of treatment group or suspected causal relationship to study drug will be recorded. Adverse events will be identified and graded using the Common Toxicity Criteria Version 4.0

Secondary outcomes

  1. pharmacokinetics of hu3F8

    Time frame: 1 year

    (Phase I) when combined with GM-CSF. Pharmacokinetics will be measured by serial blood sampling following the first two iv doses of hu3F8 as listed in Table 3. Serum hu3F8 will be measured pre-infusion and at time pre- (within an hour before hu3F8), 5 min, 3h, 6-8h, 24h, 48h, 72h, 96, 120h, 168h 216h and 264h after the first infusion of hu3F8 during cycle1 and, whenever possible, peak hu3F8 level at pre- and ~5 minutes post-infusion will also be measured for each dose of hu3F8 in subsequent cycles .

  2. assess activity of hu3F8 plus GM-CSF against HR-NB

    Time frame: 2 years

    Another secondary objective is to assess the anti-tumor activity of hu3F8 against NB and other GD2-positive tumors. Anti-tumor activity will be measured by international neuroblastoma response criteria (INRC).

  3. quantitate the response of marrow NB

    Time frame: 1 year

    will be measured using quantitative Reverse transcription-PCR (qRTPCR) and its relationship with dosage of hu3F8 explored.
