Neoadjuvant Umbrella Trial Directed by Next Generation Sequencing for Patients With Unresectable Stage III NSCLC Harboring Rare Mutations (Without EGFR Sensitizing Mutations)

This umbrella trial directed by next generation sequencing (NGS) includes patients with treatment-naive unresectable stage III non-small-cell lung cancer (NSCLC). The aim of the umbrella study is to evaluate the efficacy of induction NGS-directed targeted therapies followed by surgery for stage III NSCLC patients whose tumor harbors a rare mutation.

AbstractAlthough amplifications and mutations in receptor tyrosine kinases (RTKs) act as bona fide oncogenes, in most cancers, RTKs maintain moderate expression and remain wild-type. Consequently, cognate ligands control many facets of tumorigenesis, including resistance to anti-RTK therapies. Herein, we show that the ligands for the RTKs MET and RON, HGF and HGFL, respectively, are synthesized as inactive precursors that are activated by cellular proteases. Our newly generated HGF/HGFL protease inhibitors could overcome both de novo and acquired cetuximab resistance in colorectal cancer (CRC). Conversely, HGF overexpression was necessary and sufficient to induce cetuximab resistance and loss of polarity. Moreover, HGF-induced cetuximab resistance could be overcome by the downstream MET inhibitor, crizotinib, and upstream protease inhibitors. Additionally, HAI-1, an endogenous inhibitor of HGF proteases, (i) was downregulated in CRC, (ii) exhibited increased genomic methylation that correlated with poor prognosis, (iii) HAI-1 expression correlated with cetuximab response in a panel of cancer cell lines, and (iv) exogenous addition of recombinant HAI-1 overcame cetuximab resistance in CC-HGF cells. Thus, we describe a targetable, autocrine HAI-1/Protease/HGF/MET axis in cetuximab resistance in CRC.

TYRO3 and EPHA2 Expression Are Dysregulated in Breast Cancer

Article

ABSTRACTReceptor tyrosine kinases (RTKs) are involved in cell growth, motility, and differentiation. Deregulation of RTKs signaling is associated with tumor development and therapy resistance. Potential RTKs like TAM (TYRO3, AXL, MERTK), RON, EPH, and MET have been evaluated in many cancers like lung, prostate, and colorectal, but little is known in breast tumors. In this study, 51 luminal breast cancer tissue and 8 triple negative breast cancer (TNBC) subtypes were evaluated by qPCR for the expression of TAM, RON, EPHA2, and MET genes. Statistical analysis was performed to determine the correlation to clinical data. TYRO3 is related to tumor subtype and stage, patient's age, smoking habits, and obesity. MET expression is correlated to EPHA2 and TAM gene expression. EPHA2 expression is also related to aging and smoking habits. The expression levels of the TAM and EPHA2 genes seem to play an important role in breast cancer, being also influenced by the patient's lifestyle.

Nanoparticles targeting Sialyl-Tn for efficient tyrosine kinase inhibitor delivery in gastric cancer

Article

Gastric cancer (GC) is the fourth leading cause of cancer-related deaths worldwide and, therefore, it is urgent to develop new and more efficient therapeutic approaches. Foretinib (FRT) is an oral multikinase inhibitor targeting MET (hepatocyte growth factor receptor) and RON (recepteur d'origine nantais) receptor tyrosine kinases (RTKs) that has been used in clinical trials for several solid tumors. Targeted uptake of therapeutic polymeric nanoparticles (NPs) represents a powerful approach in cancer cell drug delivery. Previously, a nanodelivery system composed of polymeric NPs functionalized with B72.3 antibody, which targets the tumor-associated antigen Sialyl-Tn (STn), has been developed. Herein, these NPs were loaded with FRT to evaluate its capacity in delivering the drug to multicellular tumors spheroids (MCTS) and mouse models. The data indicated that B72.3 functionalized FRT-loaded PLGA-PEG-COOH NPs (NFB72.3) specifically target gastric MCTS expressing the STn glycan (MKN45 SimpleCell (SC) cells), leading to a decrease in phospho-RTKs activation and reduced cell viability. In vivo evaluation using MKN45 SC xenograft mice revealed that NFB72.3 were able to decrease tumor growth, reduce cell proliferation and tumor necrosis. NFB72.3-treated tumors also showed inactivation of phospho-MET and phospho-RON. This study demonstrates the value of using NPs targeting STn for FRT delivery, highlighting its potential as a therapeutic application in GC. STATEMENT OF SIGNIFICANCE: Despite the advances in gastric cancer therapeutics, it remains one of the diseases with the highest incidence and mortality in the world. Combining targeted therapies with a controlled drug release is an attractive strategy to reduce drug cytotoxic effects and improve specific drug delivery efficiency to the cancer cells. Thus, we developed nanoparticles loaded with a tyrosine kinase inhibitor and targeting a specific tumor glycan exclusive of cancer cells. In in vivo gastric cancer xenograft mice models, these nanoparticles efficiently reduced tumor growth, cell proliferation and tumor necrosis area and inactivated phosphorylation of targeting receptors. This approach represents an innovative therapeutic strategy with high impact in gastric cancer.

MethylGene Opts-Out of Collaboration with EnVivo Pharmaceuticals, Inc.

Montreal, Quebec and Watertown, Massachusetts. February 6, 2008 - MethylGene Inc. (TSX:MYG) and EnVivo Pharmaceuticals today announced that MethylGene has exercised its right to opt-out of further funding in its collaboration with EnVivo signed in February 2005. EnVivo will continue to research and develop histone deacetylase (HDAC) inhibitors for neurodegenerative disorders such as Huntington’s, Alzheimer’s and Parkinson’s diseases under license from MethylGene. A lead compound has been identified during the collaboration and designated as a clinical candidate by EnVivo. MethylGene will receive royalties on net sales of any approved product as well as a share of any sublicense income from future partnerships EnVivo may enter into with other companies for neurodegenerative programs. “The collaboration with EnVivo has been successful in leveraging our library of HDAC inhibitors beyond oncology. A lead candidate has been identified and we expect EnVivo will move this compound into clinical trials later this year. MethylGene has decided to exercise its right to opt out of the collaboration at the development stage for this non-core indication in order to strategically focus resources on our oncology development programs and other preclinical programs,” said Donald F. Corcoran, President and Chief Executive Officer of MethylGene. “We wish EnVivo well with the program and look forward to the opportunity to participate in the upside potential.” “The collaboration has been very productive and has provided us with a rich base from which we can move into several of the neurodegenerative diseases,” added Kees Been, President and Chief Executive Officer of EnVivo. “We look forward to advancing the lead compound towards clinical trials later this year. This would be the first brain-penetrant orally-available HDAC inhibitor that is being pursued for use as a cognition enhancing agent in neurodegenerative diseases with a potential for disease modification.” About MethylGene MethylGene Inc.
