Overcoming Cancers Resistant to HER-2 Antibodies provides general updated information on the resistance of various human cancers to anti-HER2 therapeutic antibodies. It also discusses the description of various sensitizing agents that can reverse resistance when used in combination with anti-HER2 antibodies.There have been a lot of reports in which the treatment with anti-HER2 antibodies for various cancers has resulted in clinical responses; however, there have been also subsets of cancer patients who did not respond initially, and several responding patients developed resistance following treatments. Therefore, the use of various immunosensitizing agents to reverse resistance has been considered and this book discusses each of them in depth, such as Lapatinib, Ganetespib, Paclitaxel, Celecoxib, Emantasine, Liposomal Doxorubicin, and Kinase Inhibitors. This book is a valuable source for cancer researchers, oncologists, pharmacologists and different members of biomedical field interested in fighting cancer resistance to HER-2 antibodies. Provides a general summary of various sensitizing agents that can work effectively when used in combination with anti-HER2 antibodies to reverse resistance Offers potential underlying mechanisms by which the cancer cells are either inherently resistant or become unresponsive to antibody treatment Discusses how to develop new targeted agents to underlie resistance in order to expand research on this field

Targeted therapies were initially developed to exploit the upregulation and dependence on key oncogenic pathways critical to cancer progression. Additionally, they also presented as a method to overcome chemoresistance by supplementing conventional therapeutic regimens with targeted therapies. However, the development of resistance to these combinatorial approaches has led to the reassessment of currently available therapeutic options to overcome resistance to targeted therapy. This book aims to provide an update on the advancements in the therapeutic arms race between cancer, clinicians and scientists alike to overcome resistance to targeted therapies. Subject experts provide a comprehensive overview of the challenges and solutions to resistance to several conventional targeted therapies in addition to providing a discussion on broad topics including targeting components of the tumor microenvironment, emerging therapeutic options, and novel areas to be explored concerning nanotechnology and the epigenome.

​​​​The traditional approaches to treat various cancers include chemotherapy, radiation and/or hormonal therapy. While these therapies continue to be effective in large part, they are not selective and highly toxic. There have been encouraging results in alternative therapeutic approach called antibody-mediated anti-cancer therapy, which is less toxic, more selective, and can also reverse drug/radiation resistance. Monoclonal antibodies or mAbs can be used to destroy malignant tumor cells and prevent tumor growth by blocking specific cell receptors. mAbs can bind only to cancer cell-specific antigens and induce an immunological response against the target cancer cell. The book covers the common and unique features of mAbs agains various cancer, gives the latest developments on the molecular, biochemical and genetic mechanisms of resistance by various mAbs, as well as discuss novel mAbs to overcome resistance.

Updated to include the newest drugs and those currently in development, this Fifth Edition is a comprehensive reference on the preclinical and clinical pharmacology of anticancer agents. Organized by drug class, the book provides the latest information on all drugs and biological agents—their mechanisms of action, interactions with other agents, toxicities, side effects, and mechanisms of resistance. The authors explain the rationale for use of drugs in specific schedules and combinations and offer guidelines for dose adjustment in particular situations. This edition's introduction includes timely information on general strategies for drug usage, the science of drug discovery and development, economic and regulatory aspects of cancer drug development, and principles of pharmacokinetics. Eight new chapters have been added and more than twenty have been significantly revised. A companion website includes the fully searchable text and an image bank.

This book describes recent advances in translational research in breast cancer and presents emerging applications of this research that promise to have meaningful impacts on diagnosis and treatment. It introduces ideas and materials derived from the clinic that have been brought to "the bench" for basic research, as well as findings that have been applied back to "the bedside". Detailed attention is devoted to breast cancer biology and cell signaling pathways and to cancer stem cell and tumor heterogeneity in breast cancer. Various patient-derived research models are discussed, and a further focus is the role of biomarkers in precision medicine for breast cancer patients. Next-generation clinical research receives detailed attention, addressing the increasingly important role of big data in breast cancer research and a wide range of other emerging developments. An entire section is also devoted to the management of women with high-risk breast cancer. Translational Research in Breast Cancer will help clinicians and scientists to optimize their collaboration in order to achieve the common goal of conquering breast cancer.

"Approximately 20% of all metastatic breast cancers overexpress the HER-2 receptor, a cell surface-bound receptor tyrosine kinase upstream of crucial proliferation and cell survival pathways. Trastuzumab, a humanized monoclonal antibody binding to the extracellular domain of HER-2, has proven to be a beneficial treatment for patients diagnosed as HER-2+ but continues to have limitations. With low response rates for patients when administered alone and for patients having received prior chemotherapy, the true potential of trastuzumab seems to arrive only through combination therapies. However, the majority of advanced HER-2 positive breast cancer patients still develop resistance to the therapy by the end of the first year or present de novo resistance. For this reason, it is important to continue to investigate therapies to give in combination with trastuzumab to improve progression-free survival and overall survival in this clinical setting. Two Phase II Astra Zeneca compounds: AZD0530, a dual Src and Abl kinase inhibitor and AZD8931, a pan-erbb tyrosine kinase inhibitor abrogating EGFR-, HER-2-, and HER-3-mediated signaling were explored in this context using established trastuzumab-naïve and trastuzumab-resistant cell lines. AZD0530 was not effective when administered alone and any combinations with trastuzumab showed positive responses only in those models in which some form of response to AZD0530 alone had been seen. Clinically-relevant responses to AZD8931 were seen in all cell lines tested and for this reason a head-to-head comparison was carried out with lapatinib, the FDA-approved therapy for patients progressing on trastuzumab. AZD8931 alone and in combination with trastuzumab worked effectively to stop proliferation and induce cell death in both trastuzumab-naïve and trastuzumab-resistant cell lines at clinically relevant doses. AZD8931 had similar activity to lapatinib in the SKBR3-based ER-negative cell lines, but was less active in the BT474-based ER-positive cell lines. From this study, it appears AZD8931 is a therapeutic candidate for overcoming trastuzumab resistance but further investigation is required, before translation into the clinical setting, including the use of animal models of trastuzumab-resistance, specifically in the ER-negative subtype." --
