“Cytomegalovirus (CMV)-targeted vaccination plus high-dose chemotherapy with temozolomide can lead to long-term progression-free survival (PFS) and overall survival (OS) in patients with newly diagnosed glioblastoma (GBM), according to a new study published in Clinical Care Research.
“Despite surgical resection, high-dose radiation, and chemotherapy with temozolomide, GBM patients typically survive a median of 15 months. CMV proteins are expressed in more than 90% of GBM. ‘Recent evidence has also demonstrated that CMV-specific T-cell immunity can be generated to recognize and effectively kill autologous GBM tumor cells expressing endogenous levels of the immunodominant pp65 antigen, providing compelling support for the development of CMV-directed immunotherapy for the treatment of GBM,’ stated the researchers, led by Kristen A. Batich, MD, PhD, a researcher in the departments of neurosurgery and pathology at Duke University Medical Center in Durham, North Carolina.”
“A landmark analysis of findings from the EF-14 trial testing the efficacy and safety of tumor treating fields (TTFields) for the treatment of patients with glioblastoma multiforme (GBM) has found that the risk of death was reduced by 37% and overall survival (OS) was extended by a median of 5 months with the use of the device.
“Two-, 3-, 4-, and 5-year overall and progression-free survival (PFS) rates for patients who received TTFields with adjuvant temozolomide were significantly improved over patients who received temozolomide alone, reported Roger Stupp, MD, professor of neurological surgery at Northwestern University Feinberg School of Medicine and associate director for strategic initiatives at the Robert H. Lurie Comprehensive Cancer Center.”
“Bristol-Myers Squibb Company (NYSE:BMY) today announced that CheckMate -143, a randomized Phase 3 clinical trial evaluating the efficacy and safety of Opdivo in patients with first recurrence of glioblastoma multiforme (GBM), did not meet its primary endpoint of improved overall survival over bevacizumab monotherapy. These data will be presented on May 7, 2017 at the World Federation of Neuro-Oncology Societies (WFNOS) meeting in Zurich, Switzerland.
” ‘GBM is a historically difficult disease to treat and conventional treatment options have demonstrated limited responses,’ said Fouad Namouni, M.D., head of Oncology Development and head of Medical, Bristol-Myers Squibb. ‘We remain steadfast in our pursuit of treatments for diseases with the highest unmet need and continue our work to determine how our Immuno-Oncology agents can potentially improve outcomes for these patients.’ ”
With a few exceptions, glioblastoma (GBM) remains largely incurable, and the U.S. Food and Drug Administration (FDA) has approved few treatments for the disease. Surgery (when feasible), radiation, and temozolomide are used in most patients. But even if a newly diagnosed tumor can be surgically excised, recurrences are too common.
In this blog post, I simply list some of the new treatments available in clinical trials for GBM and other high-grade brain tumors. Only drugs that have at least some preliminary results of activity are included, and the list is not meant to be fully comprehensive. The interested reader can judge for herself what might be of interest, keeping in mind that no single treatment is suitable or will work for all GBM patients. Continue reading…
“New research shows that taking molecular variables into account will improve the prognostic classification of the lethal brain cancer called glioblastoma (GBM).
“The study was led by researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
“Published in the journal JAMA Oncology, the study found that adding significant molecular biomarkers to the existing GBM classification system improves the prognostic classification of GBM patients who have been treated with radiation and the drug temozolomide.”
“Being diagnosed with cancer is a stressful, life-changing event that can evoke feelings of fear, worry, sadness, and anger. Depression gives one feelings of hopelessness and helplessness, disinterest in previously enjoyable activities, and a consistently down and sad mood. Depression often interferes with one’s ability to work, sleep, eat, and enjoy life. Patients with cancer are especially at risk for depression because of the physical changes and limitations from symptoms and treatment as well as of the uncertainty their treatment holds on their lives.”
“Five rounds of the usual chemotherapy/radiation protocol kept Alan Gross alive through decades of living with lymphoma. The treatments were grueling, but he was living proof that science was giving us ways to live with cancer. Then the disease came roaring back, and doctors told him that their medicine no longer worked. They told him to get his affairs in order.
“Every day, thousands of Americans get the end-of-life warning that Alan and his wife, Jane Townsend, heard two years ago. The words are so powerful that they can have a concussive effect, making it hard to hear, to speak, to process information. ‘Your ability to think clearly and concentrate isn’t there,’ Jane told me.”
“Treatment with autologous chimeric antigen receptor (CAR)-engineered T cells targeting the tumor-associated antigen interleukin-13 receptor alpha 2 (IL13Rα2) is associated with tumor regression in recurrent multifocal glioblastoma, according to a case report published in the Dec. 29 issue of the New England Journal of Medicine.
“Christine E. Brown, Ph.D., from the City of Hope Beckman Research Institute and Medical Center in Duarte, Calif., and colleagues describe their clinical experience with a patient with recurrent multifocal glioblastoma who received CAR-engineered T cells. Over 220 days, multiple infusions of CAR T cells were administered through two intracranial delivery routes: infusions into the resected tumor cavity followed by infusions into the ventricular system.”
“A man with deadly brain cancer that had spread to his spine saw his tumors shrink and, for a time, completely vanish after a novel treatment to help his immune system attack his disease—another first in this promising field.
“The type of immunotherapy that 50-year-old Richard Grady received already has helped some people with blood cancers such as leukemia. But the way he was given it is new, and may allow its use not just for brain tumors but also other cancers that can spread, such as breast and lung.”
