* Leukapheresis: Baseline, post-surgery;
* Dendritic Cell Vaccine (DC Vaccine): Post-Leukapheresis, administered intradermally once weekly via intradermal injection, for 4 weeks for a total of four vaccinations;
* Tumor Lysate (Lysate): Post-DC Vaccine therapy. Administered intradermally during weeks 8, 12, 16, and 28;
* Imiquimod: Self-applied topically by subject before and after scheduled DC Vaccine or Lysate administrations.

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.

Dendritic Cell Vaccine

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.

Tumor Lysate

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

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.

Leukapheresis

Edward Ziga, MD

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.

Dendritic Cell Vaccine Therapy With In Situ Maturation in Pediatric Brain Tumors

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

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

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.

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.

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

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.

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.

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