NeuroblastomaPhase 1NCT00186862
Gene Modified Allogeneic Neuroblastoma Cells For Treatment of Relapsed/Refractory Neuroblastoma
A Phase 1 study testing Interleukin-2 in people with Neuroblastoma, run by St. Jude Children's Research Hospital at 1 site in United States.
Trial summary
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. Read more about this study

About this study
Official title: Phase I Study of Chemokine and Cytokine Gene Modified Allogeneic Neuroblastoma Cells For Treatment of Relapsed/Refractory Neuroblastoma Using a Retroviral Vector
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.

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.
- Conditions
- Neuroblastoma

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Interleukin-2Drug
Also called Immunotherapy; gene transfer
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
• To determine the safety of up to eight subcutaneous injections of allogeneic neuroblastoma cells that have been genetically modified by retroviral vectors to secrete lymphotactin and Interleukin-2
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Interleukin-2 in people with Neuroblastoma, run by St. Jude Children's Research Hospital at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Jun 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
• To determine the safety of up to eight subcutaneous injections of allogeneic neuroblastoma cells that have been genetically modified by retroviral vectors to secrete lymphotactin and Interleukin-2 (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2008.
