DNX-2401: an investigational drug for the treatment of recurrent glioblastoma.

DNX-2401: an investigational drug for the treatment of recurrent glioblastoma. Expert Opin Investig Drugs. 2019 Nov 14;: Authors: Philbrick B, Adamson DC Abstract INTRODUCTION: High grade gliomas (HGG) are extremely aggressive brain malignancies that are usually fatal. Despite maximal resection, chemotherapy and radiation, these tumors inevitably recur and present a poor median overall survival (mOS); hence there is a pressing need for improved treatments.Areas covered:This review assesses DNX-2401 as a treatment of recurrent HGG. Phase I data on efficacy, safety, and tolerability are examined while insights and perspectives on future directions are offered.Expert opinion:This phase I study assessed DNX-2401 in two groups; one group received a one-time intratumoral injection of DNX-2401 without tumor resection while the second group received an intratumoral injection of DNX-2401 followed by surgical resection 14 days later and a second injection of DNX-2401 into the resection cavity. In patients that did not receive resection, the mOS was 9.5 months across all cohorts while patients in the resection group had a mOS of 13 months which is a promising extension of survival compared to historical controls. Furthermore, this study had numerous long-term survivors living for greater than 2 years at the time of recurrence. DNX-2401 was well tolerated with no drug-related Grade 3 or greater adverse events; it demonstrated some ability to provoke an immunologic re...

Authors: Xu CH, Xiao LM, Zeng EM, Chen LK, Zheng SY, Li DH, Liu Y Abstract Gliomas are aggressive type of brain tumors and cause significant human mortality world over. The frequent relapses, development of drug resistance, the adverse effects of the chemotherapy and dearth of the therapeutic targets form the major hurdles in glioma treatment. Several studies suggest that microRNAs (miRs) are involved in the development and progression of different cancers. Herein, the therapeutic potential of miR-181 was explored in human glioma cells. The results showed that miR-181 is significantly downregulated in human glioma ...

In this study, taking advantage of the currently popular computational methods for estimating the infiltration of tumor-associated normal cells in tumor samples and using weighted gene co-expression network analysis, we screened the co-expressed gene modules associated with the TME and further identified the prognostic hub genes in these modules. Furthermore, eight prognostic hub genes (ARHGDIB, CLIC1, OAS3, PDIA4, PARP9, STAT1, TAP2, and TAGLN2) were selected to construct a prognostic risk score model using the least absolute shrinkage and selection operator method. Univariate and multivariate Cox regression analysis demo...

Daria Riva Neurofibromatosis type-1 (NF1) is a monogenic tumor-predisposition syndrome creating a wide variety of cognitive and behavioral abnormalities, such as decrease in cognitive functioning, deficits in visuospatial processing, attention, and social functioning. NF1 patients are at risk to develop neurofibromas and other tumors, such as optic pathway gliomas and other tumors of the central nervous system. Few studies have investigated the impact of an additional diagnosis of brain tumor on the cognitive outcome of children with NF1, showing unclear results and without controlling by the effect of surgery, radio-...

Publication date: 6 November 2019Source: Neuron, Volume 104, Issue 3Author(s): David H. Gutmann, Helmut KettenmannOne of the most common brain tumors in children and adults is glioma or astrocytoma. There are few effective therapies for these cancers, and patients with malignant glioma fare poorly, even after aggressive surgery, chemotherapy, and radiation. Over the past decade, it is now appreciated that these tumors are composed of numerous distinct neoplastic and non-neoplastic cell populations, which could each influence overall tumor biology and response to therapy. Among these noncancerous cell types, monocytes (micr...

Purpose of review The current treatment of gliomas dovetails results of decades-old clinical trials with modern trends in chemotherapy. Molecular characterization now plays a pivotal role, and IDH mutations are key characteristics and the subject of active debate. IDH-mutant tumors produce the ‘onco-metabolite’, 2-hydroxyglutarate. Metabolic changes have become central to the understanding of tumor biology, and tumors display a fundamental metabolic change called the Warburg Effect. The Warburg Effect represents a preference for glycolysis, as opposed to oxidative phosphorylation. The present review details t...

In pediatric brain tumors, the intensification of chemotherapy has allowed for a reduction in radiotherapy (RT) volume to an involved field approach, particularly in patients with medulloblastoma. For patients with low-grade gliomas, the trend has remained to delay RT with chemotherapy; however, when RT is used, typically smaller clinical target volume margins are used. For patients with extracranial tumors, intensive chemotherapy to address systemic disease with local control is considered standard. Proton beam therapy shows significant promise in addressing both short-term and long-term toxicities in both central nervous...

Abstract We document the case of a young adult female patient who presented with multiple intracerebral and extracerebral bone lesions, the latter most prominently along the vertebral column. The spatially distinct intracerebral lesions included a superficial frontal tumor nodule as well as diffuse enlargement of the pons. Differential diagnoses ranged from neoplastic to inflammatory conditions. Repeated bone biopsies yielded uncharacteristic reactive changes whereas cerebrospinal fluid cytology pointed towards a neoplastic disease. Resection of the superficial frontal tumor nodule prompted the diagnosis of an unu...

Conclusions. In summary, RES529, the first dual TORC1/TORC2 dissociative inhibitor, lacking affinity for ABCB1/ABCG2 and having good brain penetration, was active in GBM preclinical/murine models giving credence to its use in clinical trial for patients with GBM treated in association with anti-angiogenetic compounds.

Abstract Glioma is the most common primary brain cancer, and half of patients present a diagnosis of glioblastoma (GBM), its most aggressive and lethal form. Conventional therapies, including surgery, radiotherapy, and chemotherapy, have not resulted in major ameliorations in GBM survival outcome, which remains extremely poor. Recent immunotherapy improvements for other tumors, coupled with growing knowledge of the complex interactions between malignant glioma cells and the immune system, led to an exponential increase in glioma immunotherapy research. However, immunotherapeutic strategies in GBM have not yet reac...
