“The type of brain cancer John McCain was diagnosed with July 14, glioblastoma, is among the most difficult cancers to beat. The reasons it’s so hard to treat, as I discussed previously, include its location, its genetic diversity within and across patients, and its aggressiveness. Glioblastoma (GBM) is also among the most devastating cancers in its effects since it attacks the brain, the control center for the body’s functions and the essence of an individual’s personality. Even people who survive rarely remain the same person after their treatment.”
“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.”
“Researchers at Johns Hopkins University are conducting the first clinical trials to evaluate the potential of a pinworm medication for the treatment of children and adults with newly diagnosed glioblastoma.
“Mebendazole has been used for more than 40 years to treat parasitic infections.
“Although the medication requires further testing in patients with cancer, results of a phase 1 trial have shown the medication is safe for and tolerated by adults with glioblastoma. An additional phase 1 trial is underway to assess the agent in children.”
“A treatment regimen that included the inexpensive anti-malaria drug chloroquine dramatically improved survival and quality of life for three patients with glioblastoma, according to researchers from University of Colorado Cancer Center.
“Two of the patients maintained response to treatment for more than 2 years.
” ‘We were excited that the three patients who tried the combination all had some clinical benefit,’ Jean Mulcahy Levy, MD, investigator at University of Colorado Cancer Center and pediatric oncologist at Children’s Hospital Colorado, told HemOnc Today. ‘This supports examining this combination in a broader clinical trial and assessing its efficacy in a larger patient population.’ ”
“Immunomic Therapeutics has entered an exclusive licensing agreement with Annias Immunotherapeutics for the rights to use Annia’s intellectual property regarding an immunotherapy based on antigens of cytomegalovirus (CMV). Both companies are developing new approaches for generating vaccines for cancer.
“Under the new licensing agreement, Immunomic will be able to combine LAMP-Vax, itsinvestigational nucleic acid-based immunotherapy platform, with Annia’s CMV immunotherapy platform. Duke University’s John H. Sampson, MD, PhD, and Duane A. Mitchell, MD, PhD, developed this platform, which was later licensed to Annias.”
“Using a novel approach called tumor-treating fields—which involves the delivery of low-intensity electric fields to the brain by a patient-operated device—along with standard-of-care temozolomide therapy improved overall survival and progression-free survival vs temozolomide alone in patients with glioblastoma, according to the final results of a phase III trial presented at the 2017 American Association for Cancer Research (AACR) Annual Meeting. Patients treated with tumor-treating fields plus temozolomide had a 37% reduced risk of death compared with those randomized to receive temozolomide alone.”
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…
