Available in PDF, EPUB and Kindle. Book excerpt: The idea of combining drugs and diagnostics in oncology is not new. When the selective estrogen receptor modulator tamoxifen was developed in the 1970’s for the treatment of breast cancer a positive correlation between receptor status and treatment outcome was found. As a result of this research, it was suggested to use the estrogen-receptor assay as a diagnostic test for selection of patients for tamoxifen treatment. Despite this suggestion was put forward nearly 40 years ago the adaptation of the drug-diagnostic co-development model has been relatively slow and it is only within the last decade that it has gained more widespread acceptance. The parallel development of the monoclonal antibody trastuzumab (Herceptin®, Roche/Genentech) and the immunohistochemistry assay for HER2 protein overexpression (HercepTest™, Dako) seems to have served as an inspiration to a number of stakeholders such as pharma and diagnostic companies, regulatory agencies, and academia. In recent years we have seen an increasing number of oncology drug development projects that have taken advantage of the drug-diagnostic co-development model, as outline below. Most of the new targeted anti-cancer drugs that have been introduced in recent years, such as BRAF-, ALK-, EGFR- and HER2-inhibitors, are more or less all a product of the drugdiagnostic co-development model. These drugs have shown remarkable high response rates in selected groups of patients within cancer diseases with great unmet medical needs. This Research Topic on Drug-Diagnostic Co-Development in Oncology aims to provide you with an insight into some of the diverse activities that constitute this new research area.

This book was released on 2011 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herceptin was the poster child of personalized medicine that brought forward the notion that contemporaneously developed companion diagnostics (CDx) could lead to more efficacious use of a cancer therapeutic in a selected population. Despite a gap of 12 years, the recent approvals of Zelboraf and Xalkori in quick succession by the FDA are a testament to the fact that the age of cancer therapeutics co-developed with a companion diagnostic is finally upon us. The purpose of this thesis was to test the hypotheses, that the trend for CDx based therapy launches in oncology is NOT headed towards a dramatic upturn in the next 5 years and in the view of biopharmaceutical executives - increasing price and market share of launched drugs are the dominant drivers for investing in companion diagnostics, and that the other features of CDx, such as improving the productivity of oncology drug development and reducing development costs are essentially dispensable. These hypotheses were tested using a study design that involved conducting a pilot study comprising of 18 interviews of stakeholders directly involved with the decision making of oncology drug development - to synthesize the extent of contemporaneously developed CDx to be launched with a cancer therapeutic in the coming 5 years. An analysis of the results obtained from the survey indicate, that a significant number of oncology drug launches within this decade would feature a co-developed companion diagnostic, and that despite challenges and initial trepidations over this business model - the higher probability of success, lower development costs, shorter time to market and pricing power associated with this approach, are incentives that are increasingly attracting more oncology firms to adopt this strategy for developing targeted therapeutics. Based on these findings, the original hypotheses were rejected.

The time-sensitive stages in the assay development process and agreement with clinical development timelines are critical to delivering a viable clinic-ready assay. Methods to best maneuver this are presented to help emphasize the necessary level of validation for use of an assay in a clinical setting. Each pertinent stage is then described, and key focus areas are highlighted. For certain stages of the development process, such as cut-point determination, multiple vs. single analyte, classifier training/testing, and precision determination, various statistical arguments are presented to illustrate common misconceptions or potential pitfalls.

Download or read book The Drug Development Paradigm in Oncology written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-02-12 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in cancer research have led to an improved understanding of the molecular mechanisms underpinning the development of cancer and how the immune system responds to cancer. This influx of research has led to an increasing number and variety of therapies in the drug development pipeline, including targeted therapies and associated biomarker tests that can select which patients are most likely to respond, and immunotherapies that harness the body's immune system to destroy cancer cells. Compared with standard chemotherapies, these new cancer therapies may demonstrate evidence of benefit and clearer distinctions between efficacy and toxicity at an earlier stage of development. However, there is a concern that the traditional processes for cancer drug development, evaluation, and regulatory approval could impede or delay the use of these promising cancer treatments in clinical practice. This has led to a number of effortsâ€"by patient advocates, the pharmaceutical industry, and the Food and Drug Administration (FDA)â€"to accelerate the review of promising new cancer therapies, especially for cancers that currently lack effective treatments. However, generating the necessary data to confirm safety and efficacy during expedited drug development programs can present a unique set of challenges and opportunities. To explore this new landscape in cancer drug development, the National Academies of Sciences, Engineering, and Medicine developed a workshop held in December 2016. This workshop convened cancer researchers, patient advocates, and representatives from industry, academia, and government to discuss challenges with traditional approaches to drug development, opportunities to improve the efficiency of drug development, and strategies to enhance the information available about a cancer therapy throughout its life cycle in order to improve its use in clinical practice. This publication summarizes the presentations and discussions from the workshop.

Download or read book Companion Diagnostics CDx in Precision Medicine written by Il-Jin Kim and published by CRC Press. This book was released on 2019-03-06 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a new trend in anti-cancer therapeutics development: a targeted therapy and precision medicine that targets a subgroup of patients with specific biomarkers. An in vitro diagnostic (IVD) assay is required to identify a subgroup of cancer patients who would benefit from the targeted therapy, or not likely benefit, or have a high risk of side effects from the specific drug treatment. This IVD or medical device is called a companion diagnostic (CDx) assay. It is key to have a robust CDx assay or device for the success of targeted therapy and precision medicine. This book covers the technical, historical, clinical, and regulatory aspects of CDx in precision medicine. Clearly, more and more newly developed oncology drugs will require accompanying CDx assays, and this book, with chapters contributed by renowned oncologists, provides a comprehensive foundation for the knowledge and application of CDx for precision medicine.

Download or read book Phase I Oncology Drug Development written by Timothy A. Yap and published by Springer Nature. This book was released on 2020-09-16 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed review of how oncology drug development has changed over the past decade, and serves as a comprehensive guide for the practicalities in setting up phase I trials. The book covers strategies to accelerate the development of novel antitumor compounds from the laboratory to clinical trials and beyond through the use of innovative mechanism-of-action pharmacodynamic biomarkers and pharmacokinetic studies. The reader will learn about all aspects of modern phase I trial designs, including the incorporation of precision medicine strategies, and approaches for rational patient allocation to novel anticancer therapies. Circulating biomarkers to assess mechanisms of response and resistance are changing the way we are assessing patient selection and are also covered in this book. The development of the different classes of antitumor agents are discussed, including chemotherapy, molecularly targeted agents, immunotherapies and also radiotherapy. The authors also discuss the lessons that the oncology field has learnt from the development of hematology-oncology drugs and how such strategies can be carried over into therapies for solid tumors. There is a dedicated chapter that covers the specialized statistical approaches necessary for phase I trial designs, including novel Bayesian strategies for dose escalation. This volume is designed to help clinicians better understand phase I clinical trials, but would also be of use to translational researchers (MDs and PhDs), and drug developers from academia and industry interested in cancer drug development. It could also be of use to phase I trial study coordinators, oncology nurses and advanced practice providers. Other health professionals interested in the treatment of cancer will also find this book of great value.

This book was released on 2009-08-20 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomarkers can be defined as indicators of any biologic state, and they are central to the future of medicine. As the cost of developing drugs has risen in recent years, reducing the number of new drugs approved for use, biomarker development may be a way to cut costs, enhance safety, and provide a more focused and rational pathway to drug development. On October 24, 2008, the IOM's Forum on Drug Discovery, Development, and Translation held "Assessing and Accelerating Development of Biomarkers for Drug Safety," a one-day workshop, summarized in this volume, on the value of biomarkers in helping to determine drug safety during development.

Download or read book Opportunities and Challenges in Oncology Targeted Drug Development written by Heather Stacey Tomkinson Vital and published by . This book was released on 2012 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Targeted, especially stratified or biomarker-guided, therapies offer significant advantages over traditional oncology therapies in certain settings. Selecting patients most likely to respond to a drug increases the therapeutic efficacy while reducing toxicities and may accelerate regulatory approval since smaller clinical trials are needed to demonstrate benefit. Several drugs, including vemurafenib and crizotinib have demonstrated these benefits along with commercial success. However, significant risk exists for the drug developer since approval may be threatened if they fail to meet unclear and differing yet parallel requirements for both the drug and the required companion diagnostic. Tumor biology is also increasingly complex since recent studies suggest that there are limited numbers of individual driver mutations, complicated interactions throughout signaling pathways as well as extensive tumor heterogeneity, all of which will challenge the effectiveness of targeted therapies. Clinical trial strategy decisions can greatly impact the success of a targeted therapy due to these challenges. While therapeutic efficacy is considered important, biomarker prevalence and companion diagnostic performance have been shown to be as important, yet more informative at the time decisions are made. I hypothesized that common prevalence and companion diagnostic performance thresholds are being used to guide biomarker-guided clinical trial strategy decisions for targeted oncology therapies. Seventeen interviews with preclinical, clinical or translational leads were conducted across a focused set of ten "pathway-modifying" cancer drug programs (CDK4/6, MDM2 and P13KP inhibitors) that reflect the biological complexity of future targeted therapies. These interviews provided empirical data as to how biomarkers are being incorporated into current clinical trial decisions. All respondents were planning to use a companion diagnostic for their program, however, the use of biomarkers varied significantly. For those programs with ongoing clinical trials in phase I and II, 54% (n=7/13) were pursuing a biomarker-guided strategy while 46% (n=6/13) were using an initial all-comers strategy. This fairly equal split separated when compared by phase where trials in phase I and 1/11, 60% (n=6/10) were using an all-comers strategy but for those trials in phase II (n=3), all were using biomarker-guided strategies. A key finding of the interviews was that 66.7% (n=4/6) were planning biomarker enrichment as part of expansion plans. Disproving my hypothesis, however, common thresholds for neither biomarker prevalence nor companion diagnostic performance were being used to guide these decisions. Biomarker prevalences of 50-100% were stated as potentially appropriate for an all-comers strategy. Companion diagnostic performance thresholds were even less influential as only a few respondents provided a general range of desired sensitivity and specificity. This study found that actions of drug developers are not necessarily following the emerging recommendations for targeted therapies due to the significant challenges of biomarker and companion diagnostic development.

Book excerpt: Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.

Download or read book Improving and Accelerating Therapeutic Development for Nervous System Disorders written by Institute of Medicine and published by National Academies Press. This book was released on 2014-02-06 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving and Accelerating Therapeutic Development for Nervous System Disorders is the summary of a workshop convened by the IOM Forum on Neuroscience and Nervous System Disorders to examine opportunities to accelerate early phases of drug development for nervous system drug discovery. Workshop participants discussed challenges in neuroscience research for enabling faster entry of potential treatments into first-in-human trials, explored how new and emerging tools and technologies may improve the efficiency of research, and considered mechanisms to facilitate a more effective and efficient development pipeline. There are several challenges to the current drug development pipeline for nervous system disorders. The fundamental etiology and pathophysiology of many nervous system disorders are unknown and the brain is inaccessible to study, making it difficult to develop accurate models. Patient heterogeneity is high, disease pathology can occur years to decades before becoming clinically apparent, and diagnostic and treatment biomarkers are lacking. In addition, the lack of validated targets, limitations related to the predictive validity of animal models - the extent to which the model predicts clinical efficacy - and regulatory barriers can also impede translation and drug development for nervous system disorders. Improving and Accelerating Therapeutic Development for Nervous System Disorders identifies avenues for moving directly from cellular models to human trials, minimizing the need for animal models to test efficacy, and discusses the potential benefits and risks of such an approach. This report is a timely discussion of opportunities to improve early drug development with a focus toward preclinical trials.
