Phase 2 Study of Durvalumab (MEDI4736) in Patients With Glioblastoma
Better technology is rekindling the promise of DNA medicines in oncology, including the treatment of glioblastoma. By grade school, most of us have a basic understanding of DNA, or deoxyribonucleic acid, the essential building block of human life. DNA medicines, however, are less well known and historically have been unsuccessful in delivering what 25 years ago was touted as a revolution in therapeutics. Until now. A recent resurgence of DNA medicines is due in large part to improvements in the technology that has enabled their reintroduction into the clinic. Over the past several years, Inovio, a small biotechnology company outside of Philadelphia, has begun to master the utility of DNA medicines and to optimize their delivery for clinical use in treating and preventing human disease. Inovio is currently investigating its DNA medicines using a proprietary platform that couples optimization of DNA plasmids with effi cacy-enabling delivery through the use of a smart device known as Cellectra Figure 1, Cover to treat and protect people from precancer, cancer, and infectious diseases. This device uses a short electrical pulse to open pores in the cell, allowing plasmids to enter. This ensures efficient delivery of the DNA medicine, overcoming limitations of earlier approaches. Most recently, the company has received signifi cant media coverage for INO, a DNA vaccine designed in 3 hours and brought from the bench to the clinic in 83 days to support the fight against coronavirus disease

Tissues for TCGA were collected from many sites all over the world in order to reach their accrual targets, usually around specimens per cancer type. For this reason the image data sets are also extremely heterogeneous in terms of scanner modalities, manufacturers and acquisition protocols. In most cases the images were acquired as part of routine care and not as part of a controlled research study or clinical trial.
Imaging Source Site ISS Groups are being populated and governed by participants from institutions that have provided imaging data to the archive for a given cancer type. This opportunity will generate increased participation in building these multi-institutional data sets as they become an open community resource.

J Neurol Neurosci Vol. Glioblastoma multiforme GBM is the most common and lethal primary glial neoplasm. This invasive behavior is the most contributing factor for the poor prognosis of this cancer , despite the multimodal treatment with surgery, radiotherapy and chemotherapy. Understanding and targeting the molecular mechanisms regulating glioma invasion and progression may help in identifying novel therapeutic targets for GBM treatment.
Glioblastoma Multiforme GBM is the most aggressive primary glial neoplasm [ 1 ]. Because of its high potential for infiltration and invasion, local control of GBM is difficult with either surgery or radiation therapy. Surgical excisions as wide as hemispherectomy have failed to prevent tumor recurrence or improve survival [ 2 , 3 ].
Understanding and targeting of the invasion pathways has therefore, been focus of numerous experiments and pathological studies. Invasive pathways involve complex interactions among cancer cells, extracellular matrix and white matter. These interactions are regulated by over genes [ 4 ]. There is significant genetic and phenotypic heterogeneity within the GBM [ 6 – 8 ].
Different subtypes of GBM such as pro neural PN , neural, mesenchymal and classic also differ in their different genetic profile [ 9 , 10 ]. Understanding of invasive pathways and their heterogeneity is therefore important for targeting infiltrative potential of GBM.

All rights reserved. A vaccine consisting of autologous dendritic cells loaded with autologous tumor-associated antigens AV-GBM-1 demonstrated promising survival findings in patients with newly diagnosed glioblastoma, according to updated data from a year-end analysis of an ongoing phase II clinical trial NCT The majority of patients in the study also had an appropriate immune response, as well as a decrease in tumor biomarkers. According to the findings presented at SITC, 46 out of 48 patients had established cell lines successfully, and dendritic cells were produced for 41 out of 42 patients.
Thirty-eight patients were enrolled as of the end of October , and 31 patients had started therapy. Twelve patients had completed all 8 doses. Enrollment for the single-arm, open-label study is complete with 55 patients enrolled across 8 trial sites, including sites in California, Kentucky, and New Jersey. The primary end point of the trial is OS. Patients receive AV-GBM-1 as an adjunctive therapy following primary surgery and concurrent chemoradiation.
To be eligible, patients must have recovered from surgery and be ready for concurrent chemotherapy and radiation therapy, an established autologous tumor cell line, a KPS of greater than 70, and undergone successful leukapheresis from which peripheral blood mononuclear cells were obtained to be used for generation of the dendritic cells. Patients are excluded from the study if they have recurrent glioblastoma.
The agent consists of autologous dendritic cells that are loaded with autologous tumor antigens from self-renewing tumor-initiating cells.

The last decade has seen a crescendo of FDA approvals for immunotherapies against solid tumors, yet glioblastoma remains a prominent holdout. Despite more than 4 decades of work with a wide range of immunotherapeutic modalities targeting glioblastoma, efficacy has been challenging to obtain. Earlier forms of immune-based platforms have now given way to more current approaches, including chimeric antigen receptor T-cells, personalized neoantigen vaccines, oncolytic viruses, and checkpoint blockade.
The recent experiences with each, as well as the latest developments and anticipated challenges, are reviewed. T he last decade has seen a crescendo of FDA approvals for immunotherapies against solid tumors, including melanoma and carcinomas of the lung, breast, prostate, bladder, and kidney renal cell. Glioblastoma GBM , however, remains a prominent holdout. It may seem, then, that GBM is simply a latecomer to the immunotherapeutic stage; however, the opposite is true. While, admittedly, the very first cancer vaccines were pitted against sarcomas by William Coley in the s, 16 GBM has a long history of study within the realm of tumor immunology.
Pioneers such as Brooks and Roszman were some of the first to examine the interactions of GBM with the immune system even in the early s. Immunotherapeutic modalities for GBM and other cancers now run the gamut, ranging from antibodies to adoptive cell transfers to vaccines to virally based treatments to immune checkpoint blockade. The current status for many of these will be reviewed below, with a focus on T-cell—based platforms. Strategies for the direct enlistment of T cells, most simply, have included adoptive lymphocyte transfer ALT , whereby autologous T cells are harvested; trained, expanded, and activated ex vivo against tumor; and transferred back into patients.
In its first renditions, 32 , 66 ALT encompassed the transfer of a variety of immune populations, not just T cells, which are now more increasingly the focus. CAR T-cell therapy.

Treatment of brain tumours is complex and multifaceted, and it involves many different specialists. Recent advances in translational research and molecular understanding of brain tumours raise hope that new treatments are imminent, and patients should be encouraged to participate in clinical trials. The GP has an important role in patient support and coordination of care.
Although glioblastoma multiforme GBM is the most common primary brain tumour, it has an incidence of only 6. As a result, most general practitioners GPs will care for very few patients with this condition, and low-grade tumours are even less common. The family doctor has an essential role in surveillance, support and coordination of care. Despite improvements in surgery, chemotherapy and radiotherapy, the prognosis remains poor for most patients with high-grade gliomas.
Brain tumours present a significant diagnostic challenge for primary care physicians because early symptoms are non-specific. A recent large observational study identified headache as the most sensitive symptom but found that only two in patients with headache had a brain tumour. Similarly, only 1. Observing temporal trends in symptoms and identifying cognitive issues through collateral history or simple testing may be the best way to identify patients with a tumour.

It explains how the Committee for Medicinal Products for Human Use CHMP assessed the medicine to reach its opinion in favour of granting a marketing authorisation and its recommendations on the conditions of use for Temodal. Temodal is a medicine that contains the active substance temozolomide. It is available as capsules 5 mg, 20 mg, mg, mg, mg and mg and as a powder to be made up into a solution for infusion drip into a vein.
Temodal is an anticancer medicine. It is used to treat malignant glioma brain tumours in the following groups of patients:. Treatment with Temodal should be prescribed by a doctor with experience in the treatment of brain tumours. The dose and the number of doses depend on the type of tumour being treated, whether the patient has been treated before, whether Temodal is being used alone or with radiotherapy, and how the patient responds to treatment.
Temodal capsules should be taken whole without food. If the solution for infusion is used, it should be given over a period of 90 minutes. Patients may also need to take medicines to prevent vomiting before taking Temodal. For full details, see the summary of product characteristics also part of the EPAR.
