Trial summary

This study adds an experimental treatment with another type of cells, called dendritic cells. It is hoped that these cells may stimulate the immune system to react against neuroblastoma in much the same way that vaccines cause the immune system to react to certain viruses and bacteria.

About this study

This study adds an experimental treatment with another type of cells, called dendritic cells. It is hoped that these cells may stimulate the immune system to react against neuroblastoma in much the same way that vaccines cause the immune system to react to certain viruses and bacteria. The physicians conducting this study have observed from previous research that neuroblastoma cells can be recognized by the immune system, and that they can be destroyed by immune cells.The main goal of this study is to see if giving participants this additional anti-Neuroblastoma vaccine reduces the risk of relapse following the Hematopoietic Stem Cell Transplant.

Read the detailed description

All patients who are enrolled in this study will receive all treatment at All Children's Hospital which is located at 501 6th Ave South, St. Petersburg, FL 33701. This includes autologous cell donation by apheresis, high dose cytotoxic therapy conditioning for autologous HPC transplant, post-transplant follow-up care, and all administration of dendritic cell vaccines and blood draws for post therapy immunological monitoring.

All preparation of cellular products, including hematopoietic progenitor cell products for autologous transplantation, and dendritic cell vaccine products, will be carried out in the Cell Therapy Facility located within the Moffitt Cancer Center, which is located at 12902 Magnolia Drive, Tampa, FL 33612.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Autologous Hematopoietic Progenitor Cell TransplantProcedure or surgery

    Also called stem cell transplant

    Autologous Hematopoietic Progenitor Cell (HPC) Transplant (HPCT). Blood stem cells will be collected by apheresis during the induction phase as part of standard treatment. During apheresis, the participant's blood is collected into a machine that filters out the stem cells and the filtered blood is returned to their body. The stem cells will be separated by the type of protein within the cells. Only the stem cells with a protein called CD34 will be used for the stem cell transplant.

  • KLH and Tumor Lysate Pulsed DC VaccineBiological

    Also called Dendritic Cell (DC) Vaccine

    Keyhole limpet hemocyanin (KLH) pulsed dendritic cell (DC) vaccine. Post-transplant vaccine days: +14, +28, +56 (± 10 days), +84 (± 10 days). Vaccines will be administered by intradermal injection of 0.5 mL at two nodal basins.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Occurrence of Sufficient Tumor Cell Lysate and Dendritic Cells

    The feasibility of manufacturing both a hematopoietic progenitor cell graft and multiple tumor lysate pulsed dendritic cell vaccine treatments from the same starting apheresis product, culminating in delivery of the vaccines in the immediate period following myeloablative therapy and autologous hematopoietic progenitor cell transplant period (autoHPCT). For what fraction of eligible patients can sufficient tumor cell lysate and dendritic cells, necessary for the production of the dendritic cell vaccines, be obtained? From what fraction would it be possible to make additional vaccines?

    Measured: Up to 1 year

Secondary outcomes (1)
  1. Occurrence of Dendritic Cell Related Adverse Events

    Toxicities resulting from the administration of dendritic cell vaccines in the immediate post hematopoietic cell graft period.

    Measured: Up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Autologous Hematopoietic Progenitor Cell Transplant and KLH and Tumor Lysate Pulsed DC Vaccine in people with Neuroblastoma and Neoplasms, Nerve Tissue, run by H. Lee Moffitt Cancer Center and Research Institute.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. 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: withdrawn, as of the sponsor's last update on 30 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

Occurrence of Sufficient Tumor Cell Lysate and Dendritic Cells (time frame: Up to 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 30 Aug 2017.
