Study start date: May 27, 2009
Actual date on which the first participant was enrolled.The phase II treatment schema for patients in 1st CR or ≥ 2nd CR will be the same for the vaccine as in phase I except OPT-821 will be given at a fixed dose of 150 mcg/ m\^2 and with no DLT assessment. Patients will be randomized to starting oral β-glucan in week 1 or in week 6.

Protocol
This section provides details of the study plan, including how the study is designed and what the study is measuring.Design Details
374 patients to be enrolled
Total number of participants that the clinical trial aims to recruit.Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.
Eligibility
Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.Conditions

Criteria
10 inclusion criteria required to participate
Diagnosis of neuroblastoma (NB) as defined by international criteria,[104] i.e., histopathology (confirmed by the MSKCC Department of Pathology) or bone marrow metastases plus high urine catecholamine levels.
High-risk NB as defined by risk-related treatment guidelines and the International NB Staging System,[104] i.e., stage 4 with MYCN amplification (any age) stage 4 >18 months old.
High-risk NB (as defined above) and in 1) first CR at 6 ≥ months from initiation of immunotherapy using anti-GD2 antibody, or 2) second or subsequent remission. Remission is defined as complete (CR) remission, according to the International Neuroblastoma Response Criteria.[104] Urine catecholamine levels are no longer taken into consideration when staging.
Absolute lymphocyte count ≥ 500/mcl and absolute neutrophil count ≥ 500/mcl.

Study Objectives
3 intervention groups are designated in this study
This study does not include a placebo group
Treatment Groups
Group I
ExperimentalPatients will receive a total of 7 subcutaneous injections, at weeks 1, 2, 3, 8 , 20 , 32 , and 52. Minor schedule adjus tment s are permitted , as needed Vaccines must occur a inimum of 6 days apart. The last three vaccine s can be administered up to one week earlier or later than indicated without representing a protocol violation.Patients assigned to in Group 1 will receive o ral β glucan (40 mg/kg/day) starting at week 6 or 7 and continue with approximately 2 weeks on, 2 weeks off, up to 1 cycle after the last vaccination .
Group II
ExperimentalPatients will receive a total of 7 subcutaneous injections, at weeks 1, 2, 3, 8 , 20 , 32 , and 52. Minor schedule adjus tment s are permitted , as needed Vaccines must occur a minimum of 6 days apart. The last three vaccine s can be administered up to one week earlier or later than indicated without representing a protocol violation.Group 3 will include patients who have previously received vaccine and oral β glucanglucan. Patients in this group will not be randomized using the MSK CRDB system. They will be treated as patients in Group 1 and receive o ral β glucan (40 mg/kg/day) starting at week 6 or 7 and continue with approximately 2 weeks on, 2 weeks off, up to 1 cycle after the last vaccination . They will not be eligible for primary endpoint.
Group III
ExperimentalPatients will receive a total of 7 subcutaneous injections, at weeks 1, 2, 3, 8 , 20 , 32 , and 52. Minor schedule adjus tment s are permitted , as needed Vaccines must occur a minimum of 6 days apart. The last three vaccine s can be administered up to one week earlier or later than indicated without representing a protocol violation.Patients assigned to Group 2 will receive oral β glucan (40 mg/kg/day) starting week 1 and continue with approximately 2 weeks on, 2 weeks off, up to 1 cycle after the last vaccination .
