Trial Description


This phase I/II trial studies the side effects and best dose of OPT-821 (saponin-based immunoadjuvant OBI-821) with vaccine therapy when given together with beta-glucan and how well the regimen works in treating younger patients with neuroblastoma that is likely to recur (come back), or spread (high-risk). Biological therapies, such as OPT-821 and beta-glucan, may stimulate the immune system in different ways and stop tumor cells from growing. Vaccines may help the body build an effective immune response to kill tumor cells. Giving OPT-821 with vaccine therapy together with beta-glucan may be an effective treatment for high-risk neuroblastoma.

Further Study Information


I. To determine the maximally tolerated dose of OPT-821 in a vaccine containing two antigens abundantly expressed on neuroblastoma. (Phase I)

II. To improve event-free survival (EFS) of patients who are in first or second (or later) complete/very good partial remission (CR/VGPR), i.e., have no evidence of neuroblastoma (NB) by standard studies. (Phase II)

III. To assess anti-NB activity of the bivalent vaccine plus oral beta-glucan in patients who are enrolled with evidence of minimal residual disease (MRD) by molecular biological testing of bone marrow. (Phase II)


I. To obtain preliminary data on whether subcutaneous administration of the bivalent vaccine produces an immune response directed against the target antigens in patients with high-risk neuroblastoma. (Phase I)

II. To obtain preliminary data on the anti-neuroblastoma activity of the bivalent vaccine plus oral beta-glucan in patients, including measuring the molecular response in blood and bone marrow. (Phase I)

III. To obtain data on the immune response directed against the target NB-associated antigens in patients as induced by the subcutaneous administration of the bivalent vaccine.

IV. To assess Fc fragment of immunoglobulin G (IgG), low affinity IIa, receptor (FcRIIa), Fc fragment of IgG, low affinity IIIa, receptor (FcRIIIa), integrin, alpha M (complement component 3 receptor 3 subunit) (CR3) and cluster of differentiation (CD)18 gene polymorphism of leukocytes (effector cells), with a view towards a possible association with outcome.

OUTLINE: This is a phase I, dose-escalation study of OPT-821 followed by a phase II study.

Patients receive a bivalent antigen keyhole limpet hemocyanin (KLH) conjugate vaccine and saponin-based immunoadjuvant OBI-821 (vaccine containing two antigens [GD2L, GD3L]) subcutaneously (SC) in weeks 1, 2, 3, 8, 20, 32, and 52 in the absence of disease progression or unacceptable toxicity. Beginning on week 6 or 7, patients also receive beta-glucan orally (PO) once daily (QD) for approximately 2 weeks on and 2 weeks off. Treatment with beta-glucan repeats up to 1 course after the last vaccination in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years then every 6 months for up to 5 years.

Eligibility Criteria

Inclusion Criteria:

Diagnosis of neuroblastoma (NB) as defined by international criteria, i.e., histopathology (confirmed by the Memorial Sloan-Kettering Cancer Center [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, i.e., stage 4 with (any age) or without (> 18 months old) myelocytomatosis viral related oncogene (MYCN) amplification, MYCN-amplified stage 3 (unresectable; any age), MYCN-amplified stage 4S, or disease resistant to standard chemotherapy

High-risk NB (as defined above) and in 1) first CR/VGPR by approximately 6 months from initiation of immunotherapy using 3F8 or other anti-GD2 monoclonal antibodies (mAbs), or 2) second or subsequent remission; remission is defined as complete (CR) or very good partial (VGPR) remission, according to the International Neuroblastoma Response Criteria; urine catecholamine levels are no longer taken into consideration when staging; patients can be considered as in VGPR with 1 or 2 MIBG (+) sites that were previously-irradiated

Absolute lymphocyte count >= 500/mcl

Absolute neutrophil count >= 500/mcl

Patients with grade 3 toxicities or less using the Common Toxicity Criteria (version 3.0) developed by the National Cancer Institute of the United States of America (Common Terminology Criteria for Adverse Events version 3.0) related to cardiac, neurological, pulmonary, renal, hepatic or gastrointestinal function as determined by blood tests or physical exam

Prior treatment with other immunotherapy, including antibodies, is allowed

>= 3 weeks between completion of chemotherapy or immunotherapy and first (1st) vaccination

Signed informed consent indicating awareness of the investigational nature of this program

Exclusion Criteria:

History of allergy to KLH, QS-21, OPT-821, or glucan
