Current Primary Outcome Measures  ICMJE
 (submitted: November 5, 2019)
  • Median overall survival [ Time Frame: Approximately 72 months (from the time of randomization of the first patient until approximately 31 months after randomization of the last patient) ]
    Overall survival will be defined as the time in months between randomization and death, or last follow-up if alive. Kaplan-Meier methods will be used to estimate overall survival.
  • Percentage of 111In-labeled dendritic cells migrating to the inguinal lymph nodes [ Time Frame: For each patient, migration studies will occur after vaccination #4 which occurs approximately 7 months after study consent. ]
    Within Groups I and II only, the percentage of 111In-labeled DCs migrating to the inguinal lymph nodes from the initial injection sites in the left and right groin at 48 hours post-vaccination #4 will be calculated. This analysis will be based on the first 12 patients in each arm (Group I and Group II) that receive vaccination #4.
  • Median overall survival in CMV positive participants [ Time Frame: Approximately 72 months (from the time of randomization of the first patient until approximately 31 months after randomization of the last patient) ]
    Median overall survival will be estimated in the subset of participants that are CMV positive. Overall survival will be defined as the time in months between randomization and death, or last follow-up if alive. Kaplan-Meier methods will be used to estimate overall survival.
  • Median overall survival in CMV negative participants [ Time Frame: Approximately 72 months (from the time of randomization of the first patient until approximately 31 months after randomization of the last patient) ]
    Median overall survival will be estimated in the subset of participants that are CMV negative. Overall survival will be defined as the time in months between randomization and death, or last follow-up if alive. Kaplan-Meier methods will be used to estimate overall survival.
Original Primary Outcome Measures  ICMJE
 (submitted: February 12, 2015)
  • Migration [ Time Frame: Approximately 7 months after Consent ]
    At vaccination #4, the percentage of 111In-labeled DCs reaching inguinal nodes is calculated from the initial signal at the injection site in the groin to 48 hours post-vaccination. A Wilcoxon rank-sum test will be used to compare assigned treatment groups with respect to migration.
  • Overall Survival (OS) [ Time Frame: 1 year beyond the predicted number of deaths. ]
    The Kaplan-Meier estimator will be used to describe the survival within each pre-conditioning arm. Median survival will be estimated within each treatment arm, with 95% confidence intervals. OS will be defined as the time between randomization (just prior to the 4th vaccination) and death, or last follow-up if alive. A log-rank test will be conducted comparing arms with respect to survival.

 (submitted: November 5, 2019)
  • Median progression-free survival [ Time Frame: Approximately 72 months (from the time of randomization of the first patient until approximately 31 months after randomization of the last patient) ]
    Progression-free survival will be defined as the time in months between randomization and disease progression or death. Participants alive without disease progression will be censored at the time of their last follow-up. Kaplan-Meier methods will be used to estimate progression-free survival.
  • Median progression-free survival in CMV positive participants [ Time Frame: Approximately 72 months (from the time of randomization of the first patient until approximately 31 months after randomization of the last patient) ]
    Median progression-free survival will be estimated in the subset of participants that are CMV positive. Progression-free survival will be defined as the time in months between randomization and disease progression or death. Participants alive without disease progression will be censored at the time of their last follow-up. Kaplan-Meier methods will be used to estimate progression-free survival.
  • Median progression-free survival in CMV negative participants [ Time Frame: Approximately 72 months (from the time of randomization of the first patient until approximately 31 months after randomization of the last patient) ]
    Median progression-free survival will be estimated in the subset of participants that are CMV negative. Progression-free survival will be defined as the time in months between randomization and disease progression or death. Participants alive without disease progression will be censored at the time of their last follow-up. Kaplan-Meier methods will be used to estimate progression-free survival.
Original Secondary Outcome Measures  ICMJE
 (submitted: February 12, 2015)
Progression Free Survival (PFS) [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 200 months. ]
Secondary analyses include an examination of the impact of Td tetanus pre-conditioning on subsequent PFS. The Kaplan-Meier estimator will be used to describe the PFS within each pre-conditioning arm. Median PFS will be estimated within each treatment arm, with 95% confidence intervals. If the patient remains alive without disease progression, PFS will be censored at last follow-up.

Descriptive Information
Brief Title  ICMJE DC Migration Study for Newly-Diagnosed GBM
Official Title  ICMJE Evaluation of Overcoming Limited Migration and Enhancing Cytomegalovirus-specific Dendritic Cell Vaccines With Adjuvant TEtanus Pre-conditioning in Patients With Newly-diagnosed Glioblastoma
Brief Summary This randomized phase II study will assess the impact of pre-conditioning on migration and survival among newly diagnosed glioblastoma (GBM) patients who have undergone definitive resection and completed standard temozolomide (TMZ) and radiation treatment, as well as the impact of tetanus pre-conditioning and basiliximab together on survival. After completing standard of care radiotherapy with concurrent TMZ, patients will be randomized to 1 of 3 treatment arms: 1). receive cytomegalovirus (CMV)-specific dendritic cell (DC) vaccines with unpulsed (not loaded) DC pre-coinditioning prior to the 4th vaccine; 2). receive CMV-specific DC vaccines with Tetanus-Diphtheria Toxoid (Td) pre-conditioning prior to the 4th vaccine; 3). receive basiliximab infusions prior to the 1st and 2nd DC vaccines along with Td pre-conditioning prior to the 4th vaccine. A permuted block randomization algorithm using a 1:1:1 allocation ratio will be used to assign patients to a treatment arm. Randomization will be stratified by CMV status (positive, negative), with the assignment to arms I and II being double-blinded. Effective March 2017, randomization to Group III has been terminated.
Detailed Description

A maximum of 100 patients with resected, newly-diagnosed World Health Organization (WHO) Grade IV GBM will be enrolled in this study with the expectation that approximately 79 patients will be randomized to subsequent treatment after completion of radiation treatment with concurrent temozolomide. Effective March 2017, randomization to Group III has been terminated. All consented patients will undergo a leukapheresis after resection for harvest of Peripheral Blood Lymphocytes (PBLs) for generation of DCs. Patients will then receive Radiation Therapy (RT) and concurrent TMZ at a standard targeted dose of 75 mg/m^2/d. Patients should start RT within approximately 6 weeks of surgery. Patients who experience progressive disease during radiation, are dependent on steroid supplements above physiologic levels at time of first vaccination, are unable to tolerate TMZ, or whose DCs or PBLs fail to meet release criteria will be withdrawn from the study and replaced and will not undergo repeat leukapheresis. For patients whose initial leukapheresis yields less than 3 vaccines, repeat leukapheresis may be obtained a minimum of 2 weeks from the previous leukapheresis (and may be repeated as needed) if pre-pheresis blood work is within the Apheresis Center's parameters and as long as this does not cause a significant delay in treatment for the patient.

After RT and concurrent TMZ, patients will then be randomized and begin the initial cycle of TMZ at a standard targeted dose of 150-200mg/m^2/d for 5 days at the discretion of the treating oncologist 4 (± 2) weeks after completing RT. The study cycle of TMZ comprises a targeted dose of 150-200mg/m^2/d for 5 days every 5 (± 1) weeks. All patients will receive up to a total of 10 DC vaccines given bilaterally at the groin site unless progression occurs. DC vaccines will be given intradermally (i.d.) and divided equally to both inguinal regions. DC vaccines #1-3 will be given every two weeks, thus delaying the initiation of TMZ cycle 2. Patients will then be vaccinated in conjunction with subsequent TMZ cycles every 5 (± 1) weeks for a total of 6 to 12 cycles after RT at the discretion of the treating oncologist. DCs will be given on day 21 ± 2 days of each TMZ cycle. DC vaccinations will continue during TMZ cycles up to a total of 10 unless progression occurs.

Before the first DC vaccination, all patients will receive immunization with 0.5 mL of Td intramuscularly into the deltoid muscle to ensure adequate immunity to the tetanus antigen. Those assigned to Group III will receive basiliximab 20 mg infusions 1 week before the 1st and 1 week before the 2nd vaccine. At the time of the fourth DC vaccine, patients will receive pre-conditioning per the assigned group (Group I-unpulsed DCs i.d.; Group II- Td i.d.; Group III-Td i.d.). A single dose of Td toxoid (1 flocculation unit, in 0.3 milliliters (mLs) of saline for a total volume of 0.4 mLs) or 0.4 mLs of 1 x 10^6 autologous unpulsed DCs in saline will be administered to a single side of the groin, and 0.4 mLs of saline administered to the contralateral side 12-24 hours prior to the fourth DC vaccine, which is always given bilaterally at the groin site. Patients in Groups I and II will then receive 111In-labeled DCs to compare the effects of different skin preparations on DC migration followed by Single-Photon Emission Computed Tomography and Computed Tomography (SPECT/CT) imaging immediately and at 1 and 2 days after injection. Group III will not undergo migration studies. Groups I and II will be double blinded. Group III will not be blinded.

All patients will undergo leukapheresis again for immunologic monitoring with specific assessment of baseline antigen-specific cellular and humoral immune responses and further DC generations 4 (± 2) weeks after vaccine #3. Patients will be imaged bimonthly without receiving any other prescribed anti-tumor therapy. Patients will undergo an additional leukapheresis for generation of DCs if needed to continue vaccinations.

As part of standard care for these patients, upon tumor progression, participants may undergo stereotactic biopsy or resection. As this is not a research procedure consent will be obtained separately. However, if tissue is obtained, it will be used to confirm tumor progression histologically and to assess immunologic cell infiltration and pp65 antigen escape at the tumor site.
