“Genetically modified “hunter” T cells successfully migrated to and penetrated a deadly type of brain tumor known as glioblastoma (GBM) in a clinical trial of the new therapy, but the cells triggered an immunosuppressive tumor microenvironment and faced a complex mutational landscape that will need to be overcome to better treat this aggressive cancer, Penn Medicine researchers report in a new study this week in Science Translational Medicine.”
“Investigators are seeking to determine whether the addition of ABT-414, an antibody–drug conjugate, to concomitant radiotherapy and temozolomide will improve the survival of patients with newly diagnosed glioblastoma multiforme (GBM) with epidermal growth factor receptor (EGFR) amplification.
“The phase IIb/III Intellance1 trial (NCT02573324), which is currently recruiting participants, seeks to randomize approximately 720 patients to a 2-phase experimental arm with ABT-414 or to a placebo comparator arm. Participants in the experimental arm will receive intravenous ABT-414 combined with standard therapy of oral temozolomide and radiation in a chemoradiation treatment phase, followed by ABT-414 plus oral temozolomide during an adjuvant treatment phase. The comparator arm will follow the same regimens, with an intravenous placebo to replace ABT-414.”
Stephen Western is a dedicated advocate for people dealing with brain cancer. He started this work in February 2013, when his friend was diagnosed with a type of brain tumor known as an astrocytoma. In order to help her, he began to learn all he could about the science of astrocytoma treatment.
Stephen soon realized that many more patients might benefit from his growing knowledge, so he created the website Astrocytoma Options to share this information and update it as new research emerges. He also helps run another site that focuses on the multi-drug “cocktails” often used in brain tumor treatment.
Although Stephen has no formal scientific training, he is able to help patients better understand their treatment options and stay up-to-date on the latest treatment research. To learn more about his work, I interviewed him via email:Continue reading…
“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.”
