The Emerging Therapeutic Landscape of ALK Inhibitors in Non-Small Cell Lung Cancer.

2020

The treatment of metastatic non-small cell lung cancer (NSCLC) has undergone a paradigm shift over the last decade. Better molecular characterization of the disease has led to the rapid improvement of personalized medicine and the prompt delivery of targeted therapies to patients with NSCLC. The discovery of the EML4-ALK fusion gene in a limited subset of patients affected by NSCLC and the subsequent clinical development of crizotinib in 2011 has been an impressive milestone in lung cancer research. Unfortunately, acquired resistances regularly develop, hence disease progression occurs. Afterward, modern tyrosine kinase inhibitors (TKIs), such as ceritinib, alectinib, brigatinib, and lorlat…

Second-Line Treatment of Non-Small Cell Lung Cancer: Clinical, Pathological, and Molecular Aspects of Nintedanib

2017

Abstract: Lung carcinoma is the leading cause of death by cancer in the world. Nowadays, most patients will experience disease progression during or after first-line chemotherapy demonstrating the need for new, effective second-line treatments. The only approved second-line therapies for patients without targetable oncogenic drivers are docetaxel, gemcitabine, pemetrexed, and erlotinib and for patients with target-specific oncogenes afatinib, osimertinib, crizotinib, alectinib, and ceritinib. In recent years, evidence on the role of antiangiogenic agents have been established as important and effective therapeutic targets in non-small cell lung cancer (NSCLC). Nintedanib is a tyrosine kinas…

Osteosarcoma (OS) is the second most common cause of cancer-related death in pediatric patients. The insulin-like growth factor (IGF) pathway plays a relevant role in the biology of OS but no IGF targeted therapies have been successful as monotherapy so far. Here, we tested the effect of three IGF specific inhibitors and tested ceritinib as an off-target inhibitor, alone or in combination with dasatinib, on the proliferation of seven primary OS cells. Picropodophyllin, particularly in combination with dasatinib and the combination ceritinib/dasatinib were effective in abrogating the proliferation. The ceritinib/dasatinib combination was applied to the primary cells of a 16-year-old girl wit…

Targeted Therapies for Non-Small Cell Lung Cancer

2015

The discovery of new oncogenic driver mutations and the clinical development of targeted therapies have completely changed the paradigm treatment of non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs), erlotinib, gefitinib, afatinib, ALK-inhibitors, crizotinib, and ceritinib, have been already approved for clinical use, benefiting many patients whose tumors harbor, respectively, EGFR or EML4-ALK molecular alterations. However, despite an initial benefit, tumor progression inevitably occurs, due to the development of acquired resistance to the targeted treatments. Several mechanisms of resistance have been identified, such as the seco…

The insulin-like growth factor (IGF) pathway plays an important role in several brain tumor entities. However, the lack of inhibitors crossing the blood–brain barrier remains a significant obstacle for clinical translation. Here, we targeted the IGF pathway using ceritinib, an off-target inhibitor of the IGF1 receptor (IGF1R) and insulin receptor (INSR), in a pediatric patient with an unclassified brain tumor and a notch receptor 1 (NOTCH1) germline mutation. Pathway analysis of the tumor revealed activation of the sonic hedgehog (SHH), the wingless and integrated-1 (WNT), the IGF, and the Notch pathway. The proliferation of the patient tumor cells (225ZL) was inhibited by arsenic trioxide …

Looking for a new panacea in ALK-rearranged NSCLC: may be Ceritinib?

2014

Abstract: In the past decade, the advent of targeted therapy led to a silent revolution in the war against lung cancer and a significant evolution on the concept of Phase I clinical trials design. Thanks to the specificity of their target, the new drugs have radically changed NSCLC treatment, leading to the development of personalized strategies. The accelerated approval of the first ALK-inhibitor, Crizotinib and more recently Ceritinib, without a Phase III randomized, clinical trial, has been an amazing success story in lung cancer research, marking the beginning of a new decade of targeted drugs development, characterized by modern, biomarker-driven, early clinical trial design and shorte…

(1) Background: The high-grade neuroepithelial tumor of the central nervous system with BCOR alteration (HGNET-BCOR) is a highly malignant tumor. Preclinical models and molecular targets are urgently required for this cancer. Previous data suggest a potential role of insulin-like growth factor (IGF) signaling in HGNET-BCOR. (2) Methods: The primary HGNET-BCOR cells PhKh1 were characterized by western blot, copy number variation, and methylation analysis and by electron microscopy. The expression of IGF2 and IGF1R was assessed by qRT-PCR. The effect of chemotherapeutics and IGF1R inhibitors on PhKh1 proliferation was tested. The phosphorylation of IGF1R and downstream molecules was assessed …
