Brief Title ICMJE | Immune Modulatory DC Vaccine Against Brain Tumor | ||||
Official Title ICMJE | Immune Modulatory DC Vaccine Against Diffuse Intrinsic Pontine Glioma (DIPG) and Glioblastoma (GBM) | ||||
Brief Summary | This study is designed to treat patients who have been diagnosed with brain cancer, including glioblastoma (GBM) and diffuse intrinsic pontine glioma (DIPG). The treatment uses immunomodulatory vaccine generated by autologous dendritic cells (DCs) pulsed with genetically modified tumor cells or tumor-related antigens including neoantigens to inject into patients. Vaccine-induced T cell responses have been associated with improved survival. The study will evaluate the safety and potential benefit of the novel immunomodulatory DC vaccines. | ||||
Detailed Description | Diffuse intrinsic pontine glioma (DIPG) or glioblastoma (GBM) is an aggressive malignancy. DIPG mainly occurs in the ventral pontine of childhood. The overall median survival time is 9 to 11 months. The 2-year survival rate is less than 10%. Thus DIPG has become one of the most fatal diseases in children. These tumors invade and infiltrate the surrounding brain, making complete surgical excision impossible. Several studies focused on the identification of GBM or DIPG-specific antigens and evaluated their potential for vaccine application. Immunomodulatory DC vaccines based on ex vivo genetic modifications in combination with known tumor-specific antigens may substantially enhance the activation potential of tumor-specific T cells with improved benefit to patients. Although certain antigens are highly specific in DIPG or GBM, existing immune tolerance suppresses anti-tumor immunity in cancer patients. To induce anti-cancer immune response in patients, ex vivo modification of immune modulatory antigens or immune cells will be necessary. Advanced whole exome sequencing has been developed to identify specific mutations in tumors and predict best-fit MHC-specific neoepitopes for T cell activation. In this study we will investigate novel DC vaccines based on autologous DCs pulsed with genetically modified tumor cells or related antigens such as neoantigens to induce a strong anti-tumor immunity. Early studies of DC-based vaccines targeting gliomas have shown acceptable safety and low toxicity profile. This is a multi-center randomized Phase I study to evaluate safety of novel DC vaccines. |

Study Design ICMJE | Allocation: N/A Intervention Model: Single Group Assignment Intervention Model Description: Patients with DIPG or GBM will be treated with immunomodulatory DC vaccine Masking: None (Open Label)Primary Purpose: Treatment |
||||
Condition ICMJE | Diffuse Intrinsic Pontine Glioma or Glioblastoma | ||||
Intervention ICMJE | Biological: Immunomodulatory DC vaccine to target DIPG and GBM
This study will inject DC vaccine cells near lymphoid tissue close to the tumor. The patient will receive intravenous cyclophosphamide (200 mg/m2) or oral (cytoxan) before the vaccine, followed by DC vaccine and intravenous bevacizumab (15 mg/kg) the next day. The cells will be repeatedly infused every month for six consecutive months depending on the response and the condition of the patient. The amount of DC vaccine cells per injection is based on prior report at 5-10x106. An initial dose escalation scheme will be imposed.

Study Arms ICMJE | Experimental: Immunomodulatory DC vaccine to target DIPG and GBM
Patients will receive immune modulatory treatment consisting of cyclophosphamide (200 mg/m2) and bevacizumab (15 mg/kg), before and after DC vaccine injection, respectively.
Intervention: Biological: Immunomodulatory DC vaccine to target DIPG and GBM
