Study Description

Brief summary:

This single-arm phase II study will assess the impact of tetanus pre-conditioning and adjuvant Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) on overall survival of patients newly diagnosed with World Health Organization (WHO) Grade IV glioblastoma who have undergone definitive tumor resection, are cytomegalvirus (CMV) positive and unmethylated, and completed standard temozolomide (TMZ) and radiation treatment. After completion of the standard of care radiotherapy with concurrent TMZ, patients will receive 1 cycle of dose-intensified TMZ followed by pp65-loaded dendritic cell (DC) vaccination beginning on day 23.

  • Condition or Disease:Glioblastoma
  • Intervention/Treatment: Biological: Human CMV pp65-LAMP mRNA-pulsed autologous DCs containing GM CSF
    Drug: Temozolomide
    Biological: Tetanus-Diphtheria Toxoid (Td)
    Biological: GM-CSF
    Biological: 111-Indium-labeling of Cells for in vivo Trafficking Studies
  • Phase: Phase 2
Detailed Description

Approximately 64 patients with resected, newly-diagnosed WHO Grade IV glioma who are CMV positive and in which the Methylguanine Methyltransferase (MGMT) is not methylated will be accrued to this study before standard of care radiation therapy (RT) and concurrent TMZ, with the goal of treating 48 patients with dose-intensified temozolomide and pp65 loaded dendritic cell vaccine after completion of standard RT and TMZ. All enrolled patients will undergo a leukapheresis for the generation of DCs. Patients will then receive approximately 6 weeks of the standard of care radiation therapy (RT) and concurrent TMZ at a standard targeted dose of 75 mg/m2/day. For patients whose initial leukapheresis yields less than 3 vaccines, repeat leukapheresis may be obtained. At the post-RT clinic visit, a single post-RT cycle of dose-intensified TMZ (100 mg/m2/day for 21 days) will be given. On day 23 (± 2 days) of the cycle, patients will receive the first of 3 pp65 DC vaccines. Vaccines #1-3 will be given every two weeks (± 2 days). All patients will receive up to a total of 10 DC vaccines, with vaccines administered every 35 days (± 7 days) after the third vaccine, given bilaterally at the groin site unless progression occurs with no further cycles of TMZ. DC vaccines will be given intradermally (i.d.) and divided equally to both inguinal regions. Before the first DC vaccination, patients will receive 0.5 mL of Td (tetanus and diphtheria toxoids adsorbed) intramuscularly into the deltoid muscle to ensure adequate immunity to the tetanus antigen. Patients will undergo leukapheresis again for immunologic monitoring with a specific assessment of baseline antigen-specific cellular and humoral immune responses if needed for further DC generations 14 (± 2) days after vaccine #3. Prior to pp65 DC vaccination #4,(3±1) weeks after leukapheresis 2, the vaccine site will receive a pre-conditioning intradermal injection of Td. Up to 16 patients will receive 111-Indium labeled DCs at the 4th vaccine followed by SPECT/CT imaging immediately, and at 1 and 2 days after injections.

Arms and interventions
Arm Intervention/treatment
Experimental: DC vaccination with Td preconditioning and GM CSF
This single-arm phase II study will assess the impact of tetanus pre-conditioning and adjuvant GM-CSF on overall survival of newly diagnosed GBM patients who have undergone definitive resection, are unmethylated, and completed standard temozolomide and radiation treatment. All enrolled patients will undergo a leukapheresis for the generation of DCs. Patients will then receive approximately 6 weeks of standard of care radiation therapy (RT) and concurrent TMZ. A single post-RT cycle of dose intensified TMZ (100 mg/m2/day for 21 days) will then be given. On day 23 (± 2 days) of the cycle, patients will receive the first of 3 pp65 DC vaccines every 2 weeks. All patients will receive up to a total of 10 DC vaccines
Biological: Human CMV pp65-LAMP mRNA-pulsed autologous DCs containing GM CSF
2x10^7 human CMV pp65-LAMP mRNA-pulsed autologous DCs are given intradermally and bilaterally at the groin site (divided equally to both inguinal regions). Patients will receive up to a total of 10 DC vaccines.

Drug: Temozolomide
Temozolomide is a chemotherapy drug given to all enrolled patients at the post-RT clinic visit as dose-intensified TMZ (100 mg/m2/day for 21 days).

Biological: Tetanus-Diphtheria Toxoid (Td)
Before the first DC vaccination, patients will receive 0.5 mL of Td (tetanus and diphtheria toxoids adsorbed) intramuscularly into the deltoid muscle to ensure adequate immunity to the tetanus antigen. Prior to pp65 DC vaccination #4,(3±1) weeks after leukapheresis 2 the vaccine site will receive a pre-conditioning intradermal injection of Td (1 flocculation unit (Lf), in 0.3 mL of saline for a total of 0.4 mL).

Biological: GM-CSF
Granulocyte macrophage-colony stimulating factor (GM-CSF) is a sterile, white, preservative-free lyophilized powder in a vial containing 250 mcg that will be reconstituted in 0.5 mL of sterile water for injection and used as an adjuvant with the DC vaccine.

Biological: 111-Indium-labeling of Cells for in vivo Trafficking Studies
111-In-labeled DCs are 2 x 10^7 pp65-LAMP mRNA loaded mature DCs labeled with 111-In (50 μCi / 5 x 10^7 DCs) and given i.d. as the fourth vaccine. In up to 16 patients, the fourth vaccine will be labeled with 111-In (50 μCi / 5 x 10^7 DCs) prior to injection.
Outcome Measures
  • Primary Outcome Measures: 1. Median overall survival of subjects receiving Td pre-conditioning with GM-CSF [ Time Frame: 5 years ]
    Time in months from the start of study treatment to date of death due to any cause. Patients alive as of the last follow-up has OS censored at the last follow-up date. Median OS was estimated using a Kaplan-Meier curve.
  • Secondary Outcome Measures: 1. Migration and Survival from vaccine 4 [ Time Frame: 5 years ]
    The Cox proportional hazards model will assess the impact of migration on survival after vaccine #4. Migration is defined as the maximum percentage of 111In-labeled DCs reaching inguinal nodes during the 48 hours after the 4th vaccination. The hazard ratio associated with a 1-unit change in migration will be estimated with 95% confidence intervals.CSF to site-draining inguinal lymph nodes after Td pre-conditioning and survival after vaccine # 4.
  • 2. Chemokine (C-C motif) ligand 3 (CCL3) and Survival from vaccine 4 [ Time Frame: 5 years ]
    The Cox proportional hazards model will assess the impact of CCL3 on survival post-vaccine 4. The hazard ratio associate with a 1-unit increase in CCL3 will be estimated with 95% confidence intervals
  • 3. Polyfunctionality and Survival from vaccine 4 [ Time Frame: 5 years ]
    Cox proportional hazards model will assess the association between fold change increase between baseline and the leukapheresis 2 in the frequency of pp65 antigen-specific CD8+ T cells producing three or more cytokines (IFNγ, CCL3, IL-2, TNFα, CD107a), and survival post-vaccine 4. The hazard ratio associate with a 1-unit fold change in polyfunctionality will be estimated with 95% confidence intervals.
  • 4. Maximum peak increase from vaccine 1 in percent Regulatory T cells (TReg) of CD4+ T cells [ Time Frame: 1 year ]
    The mean difference in TRegs between vaccine 1 and the maximum measured level post-vaccine 1 will be reported.
  • 5. Proportion of patients with unacceptable toxicity [ Time Frame: 1 year ]
    The proportion of patients experiencing an unacceptable toxicity will be reported. An unacceptable toxicity is defined as any grade 3 or greater toxicity that is possibly, probably, or definitely attributed to the pre-conditioning agent Td or pp65 DC vaccine that does not resolve to baseline within 3 weeks; any Grade 3 hypersensitivity reactions or autoimmune toxicity requiring steroids or hormone replacement; , and is not due to progressive disease, or any life-threatening event not attributable to concomitant medication, co-morbid event, or disease progression. Toxicities will be graded according to the National Cancer Institute Common Toxicity Criteria of Adverse Events (NCI CTCAE) version 5 criteria.
