“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.”
“Findings from a phase III clinical trial for advanced lung cancer patients could help oncologists better predict which patients are likely to receive the most benefit from immunotherapy as a first-line treatment based on the unique molecular characteristics of their tumor, according to a new study reported by a global team led by David Carbone, MD, PhD, of The Ohio State University Comprehensive Cancer – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
“In this study, researchers compared the effectiveness of the immunotherapy drug nivolumab (pronounced ‘nye VOL ue mab,’ marketed at Opdivo), with standard-of-care chemotherapy in 541 patients with previously untreated or recurrent non-small cell lung cancer (NSCLC) that expressed PDL-1 antibodies.”
“Immunotherapy may represent an effective new treatment approach for relapsed mesothelioma patients, according to a new study.
“Anti–programmed death-1 (PD-1) immunotherapy may have activity as second- or third-line therapy in malignant pleural mesothelioma (MPM), an aggressive, rare cancer associated with asbestos exposure that has no curative treatment. All MPM patients relapse despite initial chemotherapy, and median overall survival (OS) is 9 months at most, said lead author Arnaud Scherpereel, MD, PhD, head of the pulmonary and thoracic oncology department at the University Hospital (CHU) of Lille in Lille, France, at a press briefing at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting (abstract LBA8507).”

“A new study by UCLA scientists has found that the breakthrough immunotherapy drug pembrolizumab can be more effective in improving survival in people with non-small cell lung cancer (NSCLC) if they have previously received radiation therapy, compared to those without a history of radiation treatment. The findings are important as the strategies of combining radiation therapy with anti-PD-1 antibodies such as pembrolizumb are currently being explored, and have the potential to increase the overall benefit of immunotherapy for people with NSCLC, the most common form of lung cancer.”
“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.”
In November of 2014, Phil Kauffman went to his primary care doctor with what he thought was a broken rib. The doctor advised him to let it heal on its own—a standard approach for such maladies.
Phil, a retired engineering consultant who lives near San Diego, California, with his wife (their two daughters are grown), went home and waited for his rib to heal, but the pain stuck around for months.
In March of 2015 his doctor ordered an X-ray, but instead of a broken rib, it revealed suspicious spots in Phil’s lung. A CT scan found five lesions characteristic of lung cancer. His rib pain was caused by pleural effusion (liquid) in his right lung, which was extracted, and an examination of that liquid confirmed a diagnosis of stage IV non-small cell lung cancer (NSCLC).
Phil remembers that during the first week after his diagnosis he was paralyzed with fear. His brother in law, a physician, helped him snap out of it, assuring him that his treatment options guaranteed a survival period of at least a few years or maybe more, and that cancer research was progressing at such a fast rate that the prospect of extending his lifetime beyond a couple of years was good.

“Seasonal influenza vaccination resulted in increased risk of immune-related adverse events (AEs) in lung cancer patients treated with PD-1/PD-L1 checkpoint inhibitors in a small study. However, the risks of the flu itself may still outweigh the risks associated with vaccination.
” ‘Use of immune checkpoint inhibitors is now standard clinical practice for many oncology patients, and these same patients—particularly those with lung cancer—also face increased risk for complications from influenza,’ said Sacha Rothschild, MD, PhD, of University Hospital Basel in Switzerland, in a press release. ‘Although routine influenza vaccination has long been recommended for cancer patients, there are concerns that it might trigger an exaggerated immune response in this subgroup receiving checkpoint inhibitors.’ ”
“The FDA granted fast track designation to pelareorep for the treatment of metastatic breast cancer, according to the drug’s manufacturer.
“Pelareorep (Reolysin, Oncolytics Biotech) is an immuno-oncology viral-agent designed to induce selective tumor lysis, and promote an inflamed tumor phenotype through innate and adaptive immune responses, according to a company-issued press release.
“An open-label, randomized phase 2 study evaluated the addition of IV pelareorep to paclitaxel for patients with advanced or metastatic breast cancer.”
“White blood cell counts can predict whether or not lung cancer patients will benefit from immunotherapy, according to research presented at the European Lung Cancer Conference (ELCC).
” ‘Immune checkpoint inhibitors such as nivolumab and pembrolizumab significantly improve overall survival in some – but not all – patients with non-small cell lung cancer (NSCLC),’ said lead author Dr Marcello Tiseo, Coordinator of DMT Thoracic Oncology, University Hospital of Parma, Italy. ‘Researchers are looking for a predictive biomarker to select patients that will benefit from this treatment to avoid unnecessary toxicity and a waste of resources in patients who will not respond.’ ”
