Orphan drugs: trends and issues in drug development.

Research in rare diseases has contributed substantially toward the current understanding in the pathophysiology of the common diseases. However, medical needs of patients with rare diseases have always been neglected by the society and pharmaceutical industries based on their small numbers and unprofitability. The Orphan Drug Act (1983) was the first serious attempt to address the unmet medical needs for patients with rare diseases and to provide impetus for the pharmaceutical industry to promote orphan dru...


What's New in Grade II and Grade III Gliomas?

The majority of World Health Organization grade II and grade III gliomas harbor heterozygous mutations in the metabolic enzyme isocitrate dehydrogenase 1 (IDH1), and tumors with an IDH wild-type status show molecular features of a glioblastoma and simply may constitute a separate disease entity. This discovery has led to a profound shift in the way that gliomas are classified and, consequently, how treatment decisions are made. We will review the current understanding ofmutant gliomagenesis and the preclini...

Effectiveness of Stereotactic Radiotherapy and Bevacizumab for Recurrent High-grade gliomas -A Potential Therapy for IDH Wild-type Recurrent High-grade Gliomas.

This study aimed to evaluate the efficacy of stereotactic radiotherapy combined with bevacizumab (SRT-Bv) compared with Bv treatment for recurrent high-grade gliomas (HGGs).


Laser Interstitial Thermal Therapy as a Primary Treatment for Deep Inaccessible Gliomas.

Treatment strategies for deep intracranial gliomas remain limited to stereotactic biopsy in many cases due to the morbidity of aggressive surgical resection. Since no cytoreductive therapy is offered, outcomes have been demonstrably poor compared to patients who are able to undergo primary surgical resection.

FDA Expectations for Demonstrating Interchangeability.

There is a great interest from global companies who are developing biosimilars to pursue interchangeability designation for commercialization of their products in the US. An interchangeability designation will not only allow the substitutability at the pharmacy level without the intervention of a health care provider but the first sponsor who is able to garner interchangeability designation will also receive 12 months of marketing exclusivity. This paper will highlight our current understanding of FDA expec...

Surgery of Intracranial Gliomas in Children.

Gliomas are the most common type of brain cancer in the pediatric patients, constituting about 50% of all childhood intracranial tumors. This is a highly heterogeneous group, varying from the benign WHO histopathological grades I and II to malignant WHO grades III and IV. The histology and location are significant prognostic factors, which influence the decision for surgical intervention, as well as the extent of possible tumor removal. In low-grade gliomas, surgery remains the initial option and should be ...

Targeting metabotropic glutamate receptors in the treatment of primary brain tumors.

In spite of the recent advancement in the molecular characterization of malignant gliomas and medulloblastomas, the treatment of primary brain tumors remains suboptimal. The use of small molecule inhibitors of intracellular signaling pathways, inhibitors of angiogenesis, and immunotherapic agents is limited by systemic adverse effects, limited brain penetration, and, in some cases, lack of efficacy. Thus, adjuvant chemo-therapy and radiotherapy still remain the gold standard in the treatment of grade-IV ast...

Basic principles of diagnosis and treatment of gliomas.

Traditionally, gliomas were classified based on histopathological features alone. The revised World Health Organization (WHO) classification of tumors of the central nervous system from 2016 integrated molecular features into the histopathological diagnosis.

Gliomas in Children.

Gliomas are the most common primary central nervous system (CNS) neoplasms in children and adolescents and are thought to arise from their glial progenitors or stem cells. Although the exact cells of origin for most pediatric gliomas remain to be identified, our current understanding is that specific cell populations during CNS development are susceptible to particular oncogenic events during certain time windows and thus give rise to pediatric gliomas with distinct histological, molecular, and clinical fea...

Cutaneous T-cell lymphomas: Focusing on novel agents in relapsed and refractory disease.

Patients with relapsed or refractory cutaneous T-cell lymphoma (CTCL) display a dismal prognosis and their therapy represents an unmet medical need, as the best treatment strategy is yet to be determined. Exciting data on novel targeted agents are now emerging from recently concluded and ongoing clinical trials in patients with relapsed and refractory CTCL. Three FDA approved compounds are used as single agents including the oral retinoid bexarotene and histone deacetylase inhibitors romidepsin and vorinost...

Quantitative texture analysis in the prediction of IDH status in low-grade gliomas.

Molecular markers provide valuable information about treatment response and prognosis in patients with low-grade gliomas (LGG). In order to make this important information available prior to surgery the aim of this study was to explore if molecular status in LGG can be discriminated by preoperative magnetic resonance imaging (MRI).

Role of Biopsies in the Management of Intracranial Gliomas.

Gliomas encompass a wide spectrum of various histopathological entities with different management strategies and associated prognoses. In many cases, initial biopsy of the brain lesion is required, since definitive diagnosis forms the foundation for treatment decision-making. Tissue sampling can be attained during stereotactic, open, or endoscopic procedures and, overall, provides >90% diagnostic yield, while it may be significantly lower (60-70%) in small (

Endoscopic Transsphenoidal Surgery for an Adult Patient With Giant Exophytic Chiasmatic/Hypothalamic Glioma.

Optic pathway hypothalamic gliomas are intrinsic low-grade gliomas involving the optic nerve, chiasm, optic tract, and hypothalamus. The rarity of these tumors and their unpredictable course make assessment and standardization of treatment modalities difficult. Tumor debulking via various transcranial approaches was considered to be effective at controlling tumor growth, but with high rates of severe surgery-related complications. In the present case, endoscopic transsphenoidal surgery was initiated to debu...

Orphan G protein-coupled receptors: The role in CNS disorders.

There are various types of receptors in the central nervous system (CNS). G protein-coupled receptors (GPCRs) have the highest expression with a wide range of physiological functions. A newer sub group of these receptors namely orphan GPCRs have been discovered. GPR3, GPR6, GPR17, GPR26, GPR37, GPR39, GPR40, GPR50, GPR52, GPR54, GPR55, GPR85, GPR88, GPR103, and GPR139 are the selected orphan GPCRs for this article. Their roles in the central nervous system have not been understood well so far. However, rece...

Diagnostic Accuracy of 2-Hydroxyglutarate Magnetic Resonance Spectroscopy in Newly-Diagnosed Brain Mass and Suspected Recurrent Gliomas.

Isocitrate dehydrogenase (IDH) mutations result in abnormal accumulation of 2-hydroxyglutarate (2HG) in gliomas that can be detected by MRS. We examined the diagnostic accuracy of 2HG single-voxel spectroscopy (SVS) and chemical shift imaging (CSI) in both newly-diagnosed and post-treatment settings.

Temozolomide-associated Hypermutation in Gliomas.

Low-grade gliomas cause considerable morbidity and most will recur after initial therapy. At recurrence, low-grade gliomas can undergo transformation to high-grade gliomas (grade III or grade IV), which are associated with worse prognosis. Temozolomide (TMZ) provides survival benefit in patients with glioblastomas (GBMs) but its value in patients with low-grade gliomas is less clear. A subset of TMZ-treated, IDH-mutant, low-grade astrocytomas recur as more malignant tumors with thousands of de novo, coding ...

Retrospective study of nivolumab for patients with recurrent high grade gliomas.

Patients with recurrent high-grade gliomas (HGG) have limited treatment options. HGG utilize the PD-1 pathway to evade immune responses. Checkpoint inhibitors have demonstrated safety and clinical activity in patients with recurrent glioblastoma. We explored the efficacy of nivolumab in recurrent HGG with a primary objective of progression free survival (PFS) and overall survival (OS).

Clinical characteristics associated with the intracranial dissemination of gliomas.

Glioma is the most common malignant tumor of the brain and the intracranial dissemination of gliomas is the late stage of the development of the tumor. However, there is little research in literature on the occurrence of intracranial dissemination of gliomas. In order to provide a reference for clinical work, we carried out this study on intracranial dissemination of glioma.

Relationship between the extent of resection and the survival of patients with low-grade gliomas: a systematic review and meta-analysis.

Surgical resection is necessary to conduct a pathological biopsy and to achieve a reduction of intracranial pressure in low-grade gliomas patients. This study aimed to determine whether a greater extent of resection would increase the overall 5-year and 10-year survival of patients with low-grade gliomas.

Combining Clinical and Molecular Data to Predict the Benefits of Carmustine Wafers in Newly Diagnosed High-Grade Gliomas.

The purpose of this study was to retrospectively evaluate the use of carmustine wafers (CWs) in the management of high-grade gliomas (HGGs). The data from our monoinstitutional series was compared with studies reported in the literature. Special emphasis was placed on the evaluation of side effects and the analysis of extent of resection and molecular profile as risk factors.

Modeling the diffusion of D-2-hydroxyglutarate from IDH1 mutant gliomas in the central nervous system.

20-30% of diffusely infiltrative gliomas in adults contain a point mutation in isocitrate dehydrogenase 1 (IDH1mut), which increases production of D-2-hydroxyglutarate (D2HG). This is so efficient that D2HG often reaches 30 mM within IDH1mut gliomas. Yet, while up to 100 µM D2HG can be detected in the circulating cerebrospinal fluid of IDH1mut glioma patients, the exposure of nonneoplastic cells within and surrounding an IDH1mut glioma to D2HG is unknown and difficult to measure directly.

Type 1 IGF Receptor Localization in Paediatric Gliomas: Significant Association with WHO Grading and Clinical Outcome.

Nuclear localization of insulin-like growth factor receptor type 1 (IGF-1R) has been described as adverse prognostic factor in some cancers. We studied the expression and localization of IGF-1R in paediatric patients with gliomas, as well as its association with World Health Organization (WHO) grading and survival. We conducted a single cohort, prospective study of paediatric patients with gliomas. Samples were taken at the time of the initial surgery; IGF-1R expression and localization were characterized b...

Surgery of Critically Located Intracranial Gliomas.

Management of deep-seated and midline gliomas originating from thalamus, hypothalamus, basal ganglia, and brainstem presents significant challenges. Aggressive resection of such tumors is frequently impossible due to excessive morbidity and mortality rates; thus, combinations of both surgical and non-surgical treatment options should be always considered. In each individual case, there should be reasonable clinical judgment with regard to the optimal outcome providing the best possible prognosis for the pat...

Gene Fusion in Malignant Glioma: An Emerging Target for Next-Generation Personalized Treatment.

Malignant gliomas are heterogeneous diseases in genetic basis. The development of sequencing techniques has identified many gene rearrangements encoding novel oncogenic fusions in malignant glioma to date. Understanding the gene fusions and how they regulate cellular processes in different subtypes of glioma will shed light on genomic diagnostic approaches for personalized treatment. By now, studies of gene fusions in glioma remain limited, and no medication has been approved for treating the malignancy har...
