Fast-tracked Immunotherapies Offer Hope for Aggressive Brain Cancers

Patients with aggressive, high-grade malignant brain cancers, like glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), have a poor prognosis with no known curative treatment using standard resection, radiation and chemotherapy approaches. With this bleak clinical outlook, the U.S. Food and Drug Administration (FDA) has fast-tracked clinical development of several new therapies.1 According to Brad Zacharia, MD, MS, assistant professor of neurosurgery, Penn State Neuroscience Institute, and co-director of neuro-oncology, Penn State Cancer Institute, “With aggressive tumors like GBM and AA, neuro-oncologists worldwide are exploring biological and immune-targeted therapies, to identify more effective treatments. We (Penn State Health Milton S. Hershey Medical Center) are an investigational site for a number of clinical trials for these types of cancers.” (See chart.) Continue reading

Clinical Trials Investigate Novel Treatment Methods in Glioblastoma Multiforme Tumors

Glioblastoma multiforme (GBM) is one of the most medically challenging brain tumors, and can be fatal within one year.¹ Approximately 18,000 patients are diagnosed with GBM in the U.S., annually.² The current standard of treatment—maximal resection, followed by radiation with concurrent and adjuvant temozolomide chemotherapy has shown only modest improvement, with a median survival of 14.6 months, and a two-year survival rate of 26.5 percent.¹ “We need new avenues to improve survival rates,” says Assistant Professor of Neuro-Oncology Dawit Aregawi, M.D. He explains that Penn State Hershey Medical Center is conducting trials in immunologically-mediated therapy among the 90 percent of patients who experience tumor recurrences.³

While past GBM research has focused on chemotherapy, scientists have switched their focus to therapy utilizing the body’s own immune system to create tumor-fighting vaccines. Two upcoming phase 1 trials at Penn State Hershey, ICT-121 and WT2725, target cancer stem cells traditionally resistant to any form of treatment. Continue reading
