Farletuzumab for NSCLC: Exploiting a well-known metabolic pathway for a new therapeutic strategy

2015

Abstract: Introduction: The therapeutic options for NSCLC are limited barring targeted drugs, such as EGFR tyrosine-kinase inhibitors and anaplastic lymphoma kinase inhibitors, for patients bearing oncogenic mutations. Platinum-based chemotherapy remains the best strategy for most patients. New targeted drugs, including mAbs and small molecules, are currently under clinical investigation for treating NSCLC patients. Areas covered: The authors of this article focus on farletuzumab, a mAb targeting folate receptor, which has been studied in ovarian cancer and various other malignancies. In this review, the authors review its potential as therapy for NSCLC, because of the biological rationale …

Nonmetastatic Medulloblastoma of Early Childhood: Results From the Prospective Clinical Trial HIT-2000 and An Extended Validation Cohort

2020

PURPOSE The HIT-2000-BIS4 trial aimed to avoid highly detrimental craniospinal irradiation (CSI) in children < 4 years of age with nonmetastatic medulloblastoma by systemic chemotherapy, intraventricular methotrexate, and risk-adapted local radiotherapy. PATIENTS AND METHODS From 2001-2011, 87 patients received systemic chemotherapy and intraventricular methotrexate. Until 2006, CSI was reserved for nonresponse or progression. After 2006, local radiotherapy was introduced for nonresponders or patients with classic medulloblastoma (CMB) or large-cell/anaplastic medulloblastoma (LCA). DNA methylation profiles of infantile sonic hedgehog-activated medulloblastoma (SHH-INF) were subdivided i…

Pemetrexed with or without matuzumab as second-line treatment for patients with stage IIIB/IV non-small cell lung cancer.

2010

Introduction This randomized phase II study investigated pemetrexed in combination with the epidermal growth factor receptor (EGFR)-targeting monoclonal antibody matuzumab compared with pemetrexed alone as second-line therapy for patients with advanced non-small cell lung cancer. Methods Patients received pemetrexed 500 mg/m 2 every 3 weeks either alone ( n = 50) or in combination with matuzumab at either 800 mg weekly ( n = 51) or 1600 mg every 3 weeks ( n = 47). The primary end point was objective response, as assessed by an independent review committee. Results Tumor EGFR expression was detected in 87% of randomized patients. The objective response rate for the pooled matuzumab-treated a…

Circulating miR-22, miR-24 and miR-34a as novel predictive biomarkers to pemetrexed-based chemotherapy in advanced non small cell lung cancer

2013

Pemetrexed has been widely used in patients with advanced non-small cell lung cancer (NSCLC). The clinical relevance of polymorphisms of folate pathway genes for pemetrexed metabolism have not been fully elucidated yet. The aim of this study was to evaluate the expression levels of circulating miR-22, miR-24, and miR-34a, possibly involved in folate pathway, in NSCLC patients treated with pemetrexed compared with healthy controls and to investigate their impact on patient clinical outcomes. A total of 22 consecutive patients with advanced NSCLC, treated with pemetrexed-based chemotherapy and 27 age and sex matched healthy controls were included in this preliminary analysis. miR-22, miR-24, …

Does an optimal therapeutic sequence exist in advanced non-small cell lung cancer?

2008

A growing percentage of patients affected by advanced non-small cell lung cancer who progressed after first-line chemotherapy still have a good performance status and require second-line treatment.An overview of the state of the art of second-line therapeutic options is presented.The scope of the review is to give an update on the therapeutic options currently available for the second-line treatment of patients with advanced non-small cell lung cancer.Among chemotherapeutic drugs docetaxel and pemetrexed have been approved for second-line treatment of advanced non-small cell lung cancer. Although the drugs are equiactive in terms of response rate and survival parameters the latter has a cle…

Adding chemotherapy to TKI: Can we improve first-line treatment for EGFR-mutated NSCLC patients?

2016

In The Journal of Clinical Oncology , Ying Cheng and colleagues (1) have recently reported the results of a phase II randomized trial comparing pemetrexed plus gefitinib vs. gefitinib in treatment-naive, East Asian patients, with advanced non-squamous non-small cell lung cancer (NSCLC) and activating epidermal growth factor receptor (EGFR) mutations. The study met its primary end-point in the intent-to-treat population, showing a significantly longer median progression free survival (PFS) in favors of the combination arm (15.8 months) compared to single agent arm (10.9 months) [hazard ratio (HR): 0.68; 95% CI, 0.48 to 0.96; one-sided P=0.014; two-sided P=0.029].

Die „Gewichtsphobie” - Ein Diskussionsbeitrag zum Problem der „atypischen” oder „nicht näher bezeichneten”Eß- und Gewichtsstörungen -

2000

A number of authors have stated that the problem of classifying patients whose diagnosis does not meet all the criteria of anorexia and bulimia nervosa has not been satisfactorily solved. The question has been asked if it is justified to regard characteristics like "weight phobia" or body image disturbance as valid diagnostic criteria. In the present study the differences observed in three groups of patients with eating and weight disorders (anorexia: n = 42; bulimia: n = 29; atypical group without "weight phobia": n = 14) were compared using the Giessen-Test. The atypical group was shown to be significantly more "tractable" on scale 2 than the main groups, which achieved a higher score on …

Azulene as a biphenyl mimetic in orexin/hypocretin receptor agonists

2023

Azulene is a rare ring structure in drugs, and we investigated whether it could be used as a biphenyl mimetic in known orexin receptor agonist Nag 26, which is binding to both orexin receptors OX1 and OX2 with preference towards OX2. The most potent azulene-based compound was identified as an OX1 orexin receptor agonist (pEC50 = 5.79 +/- 0.07, maximum response = 81 +/- 8% (s.e.m. of five independent experiments) of the maximum response to orexin-A in Ca2+ elevation assay). However, the azulene ring and the biphenyl scaffold are not identical in their spatial shape and electron distribution, and their derivatives may adopt different binding modes in the binding site.

Dual orexin receptor blocker suvorexant attenuates hypercapnic ventilatory augmentation in mice

2022

Suvorexant (Belsomra(R)), a dual orexin receptor antagonist widely used in the treatment of insomnia, inhibits the arousal system in the brain. However, the drug’s ventilatory effects have not been fully explored. This study aims to investigate the expression of orexin receptors in respiratory neurons and the effects of suvorexant on ventilation. Immunohistology of brainstem orexin receptor OX2R expression was performed in adult mice (n = 4) in (1) rostral ventral respiratory group (rVRG) neurons projecting to the phrenic nucleus (PhN) retrogradely labeled by Fluoro-Gold (FG) tracer, (2) neurons immunoreactive for paired like homeobox 2b (Phox2b) in the parafacial respiratory group/retrotra…
