Download or read book Drug Discovery and Evaluation Methods in Clinical Pharmacology written by H.Gerhard Vogel and published by Springer Science & Business Media. This book was released on 2010-12-15 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drug Discovery and Evaluation has become a more and more difficult, expensive and time-consuming process. The effect of a new compound has to be detected by in vitro and in vivo methods of pharmacology. The activity spectrum and the potency compared to existing drugs have to be determined. As these processes can be divided up stepwise we have designed a book series "Drug Discovery and Evaluation" in the form of a recommendation document. The methods to detect drug targets are described in the first volume of this series "Pharmacological Assays" comprising classical methods as well as new technologies. Before going to man, the most suitable compound has to be selected by pharmacokinetic studies and experiments in toxicology. These preclinical methods are described in the second volume „Safety and Pharmacokinetic Assays". Only then are first studies in human beings allowed. Special rules are established for Phase I studies. Clinical pharmacokinetics are performed in parallel with human studies on tolerability and therapeutic effects. Special studies according to various populations and different therapeutic indications are necessary. These items are covered in the third volume: „Methods in Clinical Pharmacology".

Download or read book How We Do Harm written by Otis Webb Brawley, MD and published by St. Martin's Press. This book was released on 2012-01-31 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: How We Do Harm exposes the underbelly of healthcare today—the overtreatment of the rich, the under treatment of the poor, the financial conflicts of interest that determine the care that physicians' provide, insurance companies that don't demand the best (or even the least expensive) care, and pharmaceutical companies concerned with selling drugs, regardless of whether they improve health or do harm. Dr. Otis Brawley is the chief medical and scientific officer of The American Cancer Society, an oncologist with a dazzling clinical, research, and policy career. How We Do Harm pulls back the curtain on how medicine is really practiced in America. Brawley tells of doctors who select treatment based on payment they will receive, rather than on demonstrated scientific results; hospitals and pharmaceutical companies that seek out patients to treat even if they are not actually ill (but as long as their insurance will pay); a public primed to swallow the latest pill, no matter the cost; and rising healthcare costs for unnecessary—and often unproven—treatments that we all pay for. Brawley calls for rational healthcare, healthcare drawn from results-based, scientifically justifiable treatments, and not just the peddling of hot new drugs. Brawley's personal history – from a childhood in the gang-ridden streets of black Detroit, to the green hallways of Grady Memorial Hospital, the largest public hospital in the U.S., to the boardrooms of The American Cancer Society—results in a passionate view of medicine and the politics of illness in America - and a deep understanding of healthcare today. How We Do Harm is his well-reasoned manifesto for change.

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.

Download or read book An Information Theoretic Approach to Biomarker Validation written by Jennifer Erin Dienes and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Advancements in technology and therapeutic interventions have increased demand for the use of biomarkers in clinical trials over the past several decades. Biomarkers are needed to convey information about the clinical endpoint for which observational data would require impractically large numbers or long follow-up. Biomarkers can serve many different roles including predicting response to specific therapies, enriching patient populations, or in place of the clinical endpoint. Before a biomarker can be used for any of these roles it is first necessary to validate it by verifying that change and lack of change in the clinical endpoint are captured by the biomarker. Current measures for biomarker validation include sensitivity, specificity, and positive predictive value for dichotomous endpoints, and the coefficient of determination for continuous endpoints. To compare the validity of different biomarkers it would be necessary to force them to have the same variable type. The focus of this dissertation is to develop a unifying framework for biomarker validation such that different types of biomarkers can be easily compared.In Chapter 1 an introduction to information theory is given and a general framework for biomarker validation based on this theory is described. Two validation measures are proposed. These measures are shown to be functions of the currently used measures in certain situations. Arguments are made regarding the preferred use of our measures as opposed to those currently used.Estimates of the information measures such as entropy and POI are proposed in Chapter 2 for qualitative clinical endpoints and both qualitative and quantitative biomarkers. Properties of these estimates including bias, variance, and modes of convergence are derived. Simulation studies are conducted to investigate nominal coverage and width of confidence intervals of entropy near the boundary of the parameter space, information lost by categorizing continuous variables, and parameter effects on information measures when a closed form solution does not exist. These measures are used to quantify that amount of information about 3 year conversion to Alzheimer's Disease (AD) from Mild Cognitive Impairment (MCI) that is captured by various biomarkers using data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) study.Chapter 3 explores estimates of the information measures such as entropy and mutual information for quantitative clinical endpoints and both qualitative and quantitative biomarkers. Properties of these estimates including bias, variance, and modes of convergence are derived. Simulation studies are conducted to explore the finite distribution of the estimated entropy, examine parameter effects on information measures when a closed form solution does not exist, and compare various methods for constructing confidence intervals for the mutual information when the variance is unknown. These measures are used to quantify the information about cognitive decline that is captured by various biomarkers using data from the ADNI study. Lastly, a discussion of the framework presented is given in Chapter 4, including details on areas of future research.

Download or read book Biomarker Discovery in the Developing World Dissecting the Pipeline for Meeting the Challenges written by Sanjeeva Srivastava and published by Springer. This book was released on 2016-09-30 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is oriented towards post-graduates and researchers with interest in proteomics and its applications in clinical biomarker discovery pipeline. Biomarker discovery has long been the research focus of many life scientists globally. However, the pipeline starting from discovery to validation to regulation as a diagnostic or therapeutic molecule follows a complex trajectory. This book aims to provide an in-depth synopsis on each of these developmental phases attendant to biomarker “life cycle” with emphasis on the emerging and significant role of proteomics. The book begins with a perspective on the role of biorepositories and need for biobanking practices in the developing world. The next chapter focuses on disease heterogeneity in context to geographical bias towards susceptibility to the disease and the role of multi-omics techniques to devise disruptive innovations towards biomarker discovery. Chapter 3 focuses on various omics-based platforms that are currently being used for biomarker discovery, their principles and workflow. Mass spectrometry is emerging as a powerful technology for discovery based studies and targeted validation. Chapter 4 aims at providing a glimpse of the basic workflow and considerations in mass spectrometry based studies. Rapid and aptly targeted research funding has often been deemed as one of the decisive factors enabling excellent science and path breaking innovations. With the need for sophistication required in multi-omics research, Chapter 5 focuses on innovative funding strategies such as crowdfunding and Angel philanthropy. Chapter 6 provides the latest advances in education innovation, the premise and reality of bioeconomy especially in a specific context of the developing world, not to mention the new concept of “social innovation” to link biomarkers with socially responsible and sustainable applications. Chapter 7, in ways similar to biomarkers, discusses the biosimilars as a field that has received much focus and prominence recently due to their immense potential in clinical and pharmaceutical innovation literatures. The broader goal post-biomarker discovery is to translate their use in clinics. However, the road from bench-to-bed side is arduous and complex that is subject to oversight from various national and international regulatory bodies. Chapter 8 underscores these regulatory science considerations and provides a concise overview on intellectual property rights in biomarker discovery. Thus, this book contributed by eminent biomarker scientists, clinicians, translational researchers and social scientists holistically covers the various facets of the biomarker discovery journey from “cell to society” in developing world. The lessons learned and highlighted here are of interest to the life sciences community in a global and interdependent world.
