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.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
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...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
