Abstract:
Despite new additions to the standard of care therapy for high grade primary malignant brain tumors, the prognosis for patients with this disease is still poor. A small contingent of clinical researchers are focusing their efforts on testing the safety, feasibility and efficacy of experimental active and passive immunotherapy approaches for gliomas and are primarily conducting Phase I and II clinical trials. Few trials have advanced to the Phase III arena. Here we provide an overview of the cellular therapies and vaccine trials currently open for patient accrual obtained from a search of http://www.clinicaltrials.gov. The search was refined with terms that would identify the Phase I, II and III immunotherapy trials open for adult glioma patient accrual in the United States. From the list, those that are currently open for patient accrual are discussed in this review. A variety of adoptive immunotherapy trials using ex vivo activated effector cell preparations, cell-based and non-cell-based vaccines, and several combination passive and active immunotherapy approaches are discussed.
Insights
Despite advances, high-grade brain tumor prognosis remains poor. This review covers ongoing immunotherapy clinical trials, including cellular therapies and vaccines, for adult glioma patients in the US.
Area of Science:
- Oncology
- Immunotherapy
- Neuro-oncology
Background:
- High-grade primary malignant brain tumors, including gliomas, have a poor prognosis despite current standard of care therapies.
- Experimental immunotherapy approaches, including active and passive strategies, are being investigated in early-phase clinical trials.
Purpose of the Study:
- To provide an overview of currently open immunotherapy clinical trials for adult glioma patients in the United States.
- To identify and discuss cellular therapies, vaccine trials, and combination immunotherapy approaches.
Main Methods:
- A systematic search of clinicaltrials.gov was conducted.
- The search focused on Phase I, II, and III immunotherapy trials for adult glioma patients in the US that are currently open for accrual.
- Identified trials involving adoptive immunotherapy, cell-based and non-cell-based vaccines, and combination approaches were reviewed.
Main Results:
- A variety of immunotherapy trials are currently open for patient accrual.
- These include adoptive immunotherapy with ex vivo activated effector cells, various vaccine strategies (cell-based and non-cell-based), and combined passive and active immunotherapy approaches.
Conclusions:
- Immunotherapy represents a promising area of research for high-grade gliomas.
- Several novel immunotherapy strategies are in active clinical development, offering potential new treatment avenues for patients.

Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
