Humanized 3F8 Monoclonal Antibody (Hu3F8) When Combined With Interleukin-2 in Patients With High-Risk Neuroblastoma and GD2-positive Solid Tumors

Completed · Phase 1

Conditions studied: Neuroblastoma

In brief

The purpose of this study is to find out if "humanized 3F8" (Hu3F8) when combined with interleukin-2 (rIL2) is safe for treating neuroblastoma and other cancers. A phase 1 study means the investigators are trying to find out what side effects happen when higher and higher doses of a drug are used. The investigators want to find out what effects, good and/or bad, Hu3F8 combined with rIL2 has on cancer. The amount of Hu3F8 that patients gets will depend on when they start treatment on this study. The amount of rIL2 will be the same for all patients. The investigators also want to find out more about how Hu3F8 works and how effective it is in attacking the disease when combined with rIL2.

You may qualify if…

Patients must have either (1) a diagnosis of NB as defined by international criteria,84 i.e., histopathology (confirmed by the MSKCC Department of Pathology) or BM metastases plus high urine catecholamine levels, or (2) a tumor that is GD2-positive.
o A non-NB tumor is defined as GD2-positive by immunostaining with m3F8. If fresh or frozen tumor is not available for immunostaining, patients will be considered eligible if published reports show that >50% of that tumor type is GD2-positive by immunohistochemistry. (Note: Tissues must be fresh/frozen as fixed, paraffin-embedded specimens are unsuitable for anti-GD2 immunostaining). Tumors known to be GD2- positive by this criteria do not need immunostaining. These include: Melanoma (>50%), Desmoplastic small round cell tumors (70%), Osteosarcoma (88%) and Soft tissue sarcomas including liposarcoma, fibrosarcoma, malignant fibrous histiocytoma, leiomyosarcoma, and spindle cell sarcoma (93%).
Patients must have either (1) refractory or relapsed high-risk NB (including MYCN-amplified stage 2/3/4/4S of any age and MYCN-nonamplified stage 4 in patients greater than 18 months of age)resistant to standard therapy*, or (2) refractory or relapsed GD2-positive tumor after receiving available life-prolonging therapies.
For NB, standard therapy generally includes 5-8 cycles of high dose induction chemotherapy followed by resection of gross residual tumor, with or without myeloablative chemotherapy with peripheral blood stem cell rescue and radiation therapy to the primary site. There are also salvage chemotherapy regimens for residual disease after standard induction therapy or for relapsed NB. Some examples of these chemotherapy combinations are: high-dose cyclophosphamide, topotecan and vincristine; high-dose cyclophosphamide, irinotecan and vincristine; irinotecan and temozolomide; or ifosfamide, carboplatin and etoposide.
Patients must be older than 1 year of age.
Prior treatment with murine 3F8 is allowed. Patients with prior m3F8, hu3F8, ch14.18 or hu14.18 treatment must have HAHA antibody titer less than or = to 1300 Elisa units/ml
White blood cell count ≥1000/ul
Absolute neutrophil count ≥500/ul
Absolute lymphocyte count ≥500/ul
Platelet count ≥25,000/ul
No chemotherapy or immunotherapy for a minimum of three weeks prior to study enrollment
Women of child-bearing potential must be willing to practice an effective method of birth control while on treatment
