Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Neuroblastoma affects approximately 500 children a year in the United States. When the tumor occurs in infants, it is frequently localized and responds well to therapy. Even disseminated disease can be eradicated in about 75% of infants, and indeed may undergo spontaneous remission. In older children, the prognosis is far worse, and 80% or more of those with disseminated tumor can be expected to relapse within 3 years.

This study will utilize the concept of exploiting the immune system to eradicate neuroblastoma. In tumors in which there is consistent expression of tumor specific antigens as part of the malignant process, it may be possible to generate immune T-cells ex-vivo or in-vivo by using the specific protein or peptide(s) derived therefrom and eradicate the tumor. This study will evaluate the use of four to eight injections of IL-2 gene-transduced autologous neuroblastoma cells to induce a local, polyclonal T-cell infiltrate as well as an anti-tumor immune response.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Secondary objectives for this protocol included the following:

* To determine whether major histocompatibility complex (MHC) restricted or unrestricted antitumor immune responses are induced by injection of modified allogeneic neuroblasts and the cell doses required to produce these effects.
* To obtain preliminary data on the antitumor effects of this treatment regimen.

Group Type OTHER

Interleukin-2

Intervention Type DRUG

A genetically modified (retroviral) allogeneic tumor vaccine coupled with the human interleukin-2. Patients were treated with 4 injections of these gene-modified tumor cells. The first two were given at weeks 1 and 2. Patients then had a 2 week rest and the remaining 2 injections were given at weeks 4 and 5. A complete evaluation for evidence of toxicity and response were performed at week 8.

At this week 8 evaluation, if there was no excessive toxicity, progressive disease requiring therapy, and if more transduced cells are available, patients had the option to receive 4 additional injections. These additional injections were separated by 1 month at the higher of the two dosage levels originally received.
