About this study

Official title: A Phase I Study of Dendritic Cell Vaccine Therapy With In Situ Maturation for Pediatric Brain Tumors

DC vaccine manufactured and partially matured using our standard operating procedures, developed in collaboration with the HGG Immuno Group, then administered through imiquimod treated skin will be safe and feasible in children with refractory brain tumors. This will result in anti-tumor immunity that will prolong survival of subjects treated and results will be consistent with the outcomes found for subjects treated by HGG Immuno Group investigators. Study treatment will correlate with laboratory evidence of immune activation. Correlative studies will also reveal targets in the immune system which can be exploited to improve response for patients on successor trials.

What participants receive

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

  • Dendritic Cell VaccineBiological

    Also called DC Vaccine

    Post-Leukapheresis. Subjects will receive DC Vaccine administered once weekly, via intradermal injection, for 4 weeks for a total of four vaccinations, per study protocol.

  • Tumor LysateBiological

    Also called Tumor Cell Lysate, Lysate of Tumor

    Post-DC Vaccine therapy. Up to 1.5 mg of Lysate of tumor per dose administered via intradermal injection at intervals defined by study protocol.

  • ImiquimodOther

    Also called Aldara

    Subjects will self-apply Imiquimod topically to each designated vaccine site before and after scheduled administrations of DC Vaccine or Lysate, per study protocol.

  • LeukapheresisProcedure or surgery

    Also called Pheresis

    Baseline, post-surgery. Subjects will undergo leukapheresis procedure during baseline, after recovery from surgery to collect peripheral blood mononuclear cells (PBMCs) from which dendritic cells will be obtained, per study protocol.

What is being measured

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

  1. Rate of Toxicity in Study Participants Receiving Protocol Therapy

    Rate of treatment-limiting toxicities (TLT) and/or adverse events in study participants receiving protocol therapy.

    Measured: Up to 28 Weeks

  2. Rate of Feasibility of Protocol Therapy in Study Participants

    Rate of feasibility of protocol therapy in study participants. Feasibility refers to clinical feasibility - whether or not the patient can have enough monocytes removed to manufacture Dendritic Cells.

    Measured: Up to 4 Weeks

Secondary outcomes (5)
  1. Rate of Prolonged Survival or Prolonged Progression-Free Survival in Study Participants

    Rate of prolonged survival or prolonged progression-free survival in study participants. Overall Survival is defined as the time elapsed from the start of treatment until death. For surviving patients, follow-up will be censored at the date of last contact. Progression-Free Survival (PFS) is defined as the time elapsed from the start of treatment to the date of documented progression or death, whichever comes first.

    Measured: Up to 24 Months

  2. Rate of Measurable Immune Response in Subjects Receiving Protocol Therapy.

    Rate of measurable immune response in subjects receiving protocol therapy demonstrated by measurement levels of Myeloid Derived Suppressor Cells before and after treatment.

    Measured: Up to 24 months

  3. Comparison of clinical parameters of study participants versus associated outcomes for patients on other DC/Imiquimod studies.

    A comparison of whether the clinical parameters associated with outcomes described for patients on other DC/Imiquimod protocols hold for subjects treated on this study.

    Measured: Up to 24 Months

  4. Estimation of the Proportion of Subjects with Recurrent Pediatric Brian Tumors who are able to complete DC Vaccine therapy and DC Vaccine + Lysate Therapy.

    Estimation of the proportion of subjects with recurrent pediatric brain tumors who are able to receive all administrations of DC, and the proportion who are able to receive all administrations of DC and Lysate.

    Measured: Up to 24 months

  5. Identification of Parameters Associated with Poorer Activity of the Vaccine in Study Participants

    Identification of parameters associated with poorer activity of the DC Vaccine in Study Participants in order to develop therapies to augment vaccine therapy.

    Measured: Up to 24 Months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dendritic Cell Vaccine, Tumor Lysate and Imiquimod in people with Glioma and Brain Cancer, run by Edward Ziga 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?

The sponsor lists 18 inclusion and 9 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: stopped early, as of the sponsor's last update on 10 Mar 2017. 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 was stopped early (reason given: Lack of Accrual). Results are not available in the source record.

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?

Rate of Toxicity in Study Participants Receiving Protocol Therapy (time frame: Up to 28 Weeks). The study lists 2 primary outcomes in all. 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 10 Mar 2017.
