Dendritic Cell Vaccination With Standard Postoperative Chemoradiation for the Treatment of Adult Glioblastoma
Study Details
Study Description
Brief Summary
Effective treatments are desperately needed for glioblastoma (GBM) patients. This phase I clinical trial assesses the safety of a novel personalized dendritic-cell vaccine administered to GBM patients shortly after completing standard-of-care treatments. Secondary outcomes will evaluate patient progression-free survival and overall survival.

Phase 1 |
Detailed Description
This is a single arm (non-randomized) first-in-man pilot study to evaluate the safety and feasibility of delivering a dendritic cell vaccine in nine to twenty-four (n=9-24) adult patients diagnosed with glioblastoma (GBM) after undergoing neurosurgical tumor resection, and in whom a neuropathological diagnosis has been established. Standard of care chemotherapy and radiation therapy shall be followed as per routine neuro-oncologic paradigms after which patients enrolled into this study will receive a personalized vaccine beyond standard of care. Effective adjuvant therapies are urgently needed for these patients given that standard of care is rarely successful in preventing recurrence among GBM patients, nor death among relapsed patients with this very poor-prognosis tumor type. The study is constructed in a 3+3 algorithm for three steps of dose escalation with rigorous and mandatory safety monitoring.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Dendritic cell vaccine: Starting dose This arm will evaluate the safety of administering a total dendritic cell dose of 3.5 x 10^6. A total of 3-6 patients will be enrolled with this dose. If this dose is associated with unacceptable side effects, as detailed in the study protocol, no further patients will be enrolled at this dose. |
Biological: TH-1 Dendritic Cell Immunotherapy
Adult patients with histopathologically diagnosed glioblastoma will be eligible for this novel, personalized dendritic cell vaccine after completing standard of care chemoradiation.
|
| Experimental: Dendritic cell vaccine dose de-escalation If unacceptable side effects, as detailed in the study protocol, are identified at a total dose of 3.5 x 10^6, then a cohort of 3-6 enrolled patients will receive a de-escalated total dendritic cell dose of 1.75 X 10^6. |
Biological: TH-1 Dendritic Cell Immunotherapy
Adult patients with histopathologically diagnosed glioblastoma will be eligible for this novel, personalized dendritic cell vaccine after completing standard of care chemoradiation.
|
| Experimental: Dendritic cell vaccine dose escalation one If no unacceptable side effects, as detailed in the study protocol, are identified at a total dose of 3.5 x 10^6, then a cohort of 3-6 enrolled patients will receive an escalated total dendritic cell dose of 7.0 X 10^6. |
Biological: TH-1 Dendritic Cell Immunotherapy
Adult patients with histopathologically diagnosed glioblastoma will be eligible for this novel, personalized dendritic cell vaccine after completing standard of care chemoradiation.
|
| Experimental: Dendritic cell vaccine dose escalation two If no unacceptable side effects, as detailed in the study protocol, are identified at a total dose of 7.0 x 10^6, then a cohort of 3-6 enrolled patients will receive an escalated total dendritic cell dose of 1.4 X 10^7. |
Biological: TH-1 Dendritic Cell Immunotherapy
Adult patients with histopathologically diagnosed glioblastoma will be eligible for this novel, personalized dendritic cell vaccine after completing standard of care chemoradiation.

Outcome Measures
Primary Outcome Measures
- Safety and potential toxicity of Th-1 dendritic cell immunotherapy [Two years]
Patients will be monitored for adverse events as dictated by CTCAE version 5.
Secondary Outcome Measures
- Overall survival of patients receiving Th-1 dendritic cell immunotherapy [Minimum 2 years from time of diagnosis]
Length of survival for patients who receive this vaccine will be tabulated.
- Progression-free survival of patients receiving Th-1 dendritic cell immunotherapy [Minimum 2 years from time of diagnosis]
If there is tumor recurrence, the time from diagnosis until recurrence will be collected
