Vaccines Based on Immunotherapies Being Tested in Phase 2 Trials in Brain Cancer

Excerpt:

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, its investigational 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.”

‘Out-of-the-Box’ Approach Plus Temozolomide Extends Survival in Glioblastoma

Excerpt:

“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.”

Super Advocate: Stephen Western Helps Brain Cancer Patients Keep Up with the Latest Research


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…


Results of Glioblastoma Clinical Trial Show Safety and Clinical Benefit of CAR T Cell Therapy

Excerpt:

“Glioblastoma is the most common brain tumor in humans and also one of the most difficult cancers to treat; patients with this type of cancer only survive about one year from time of diagnosis. Researchers at Baylor College of Medicine, Texas Children’s Cancer Center, and the Center for Cell and Gene Therapy at Baylor, Texas Children’s Hospital and Houston Methodist are investigating a new treatment option using modified T cells with anti-tumor properties with the goal of improving outcomes for patients with glioblastoma.

Their research focuses on engineered T cells that target the protein HER 2 expressed in low levels in . Results of a Phase 1 study published in the current issue of JAMA Oncology established the safety of these HER 2-specific, chimeric antigen receptor modified T cells (CAR T cells) when infused in to patients in increasing doses and, importantly, results also showed a clinical benefit to patients.”

Opdivo Fails to Demonstrate Survival Benefit in Phase 3 Brain Cancer Trial

Excerpt:

“Patients with glioblastoma multiforme, a type of brain cancer, who recurred following radiation therapy and Temodal (temozolomide), did not survive longer when treated with the PD-1 inhibitor Opdivo (nivolumab) compared to standard-of-care treatment with Avastin (bevacizumab).

The findings mean that the randomized CheckMate -143 Phase 3 trial (NCT02017717) has failed to meet its primary objective.

” ‘[Glioblastoma multiforme] is a historically difficult disease to treat and conventional treatment options have demonstrated limited responses,’ Fouad Namouni, MD, head of Oncology Development and head of Medical at Bristol-Myers Squibb, said in a news release. ‘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.’ ”

Vaccine/Chemotherapy Combination Improves Survival in Glioblastoma

Excerpt:

“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.”

TTFields Significantly Improve Survival in GBM

Excerpt:

“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 Announces Results from CheckMate -143, a Phase 3 Study of Opdivo (nivolumab) in Patients with Glioblastoma Multiforme

Excerpt:

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.’ ”

Brain Cancer Survival Improves with Novel Electrical Device, Data Suggest

Excerpt:

“A wearable medical device that delivers electrical fields through the scalp helped to extend the survival of patients with lethal brain tumors, according to data presented Sunday.

“In a study involving major medical centers in the United States and abroad, the novel treatment was used to administer alternating, low-intensity ‘tumor-treating fields’ to newly diagnosed glioblastoma patients who also were getting chemotherapy. Such electrical fields may block the division of cancer cells and cause their demise, according to Roger Stupp, the study’s lead investigator and a neuro-oncologist at the Northwestern University Feinberg School of Medicine.”
