Drug Discovery For Psychiatric Disorders

This is a wide scope and in-depth coverage of the state of the art and future directions in drug discovery for major psychiatric disorders.

Since the pioneering pharmacotherapy for treatment of schizophrenia in the 1950s by antipsychotics, only a few major innovations have been made, pointing to a general stagnation in the field of pharmacology of schizophrenia. Drug Discovery for Schizophrenia covers new insights in the field of schizophrenia with an aim to advance the understanding of scientists and clinicians in this area and to fuel drug discovery. The book outlines a change in the way schizophrenia is treated by moving away from focusing only on treating symptoms in patients. Innovative drugs emerge from deeper comprehension of the pathological processes that emerge earlier in life, hence, providing strategies for preventative therapy to alter the course of this mental disorder. Amongst other current topics, the book covers new findings in genetics and epigenetics, progress in animal models for schizophrenia and the usage of induced pluripotent stem cells. The combination of these important areas benefit psychiatric neuroscience, filling the gaps in the knowledge of neurobiology of schizophrenia and providing novel perspectives for future drug development.

The book reviews clinical trial methodology as it pertains to drug development in psychiatry. The reader will understand the process of drug development in psychiatry from discovery through marketing with the help of clinically relevant examples. The reader will appreciate the history of drug development in psychiatry dating back to the era of serendipitous discovery and culminating in an era of new and highly focused targets. Readers will understand how drug development in psychiatry has changed and adapted with the discovery of novel mechanism of action drugs. Novel drugs and disease targets have changed the way developers and regulatory agencies think about clinical trial methodology. The book elucidates how biomarkers, genetics and advances in neuroscience and neuroimaging have influenced drug development approaches, which will ultimately change the practice of psychiatry. The book will be broken down into the following sections: a. Prior to the 1960s - Drug discovery by chance observation b. The last 50 years – refined targeting of CNS drugs without the discovery of mechanistically new drugs c. The future – the discovery and development of mechanistically new drugs. The examination of new targets, genetics and biomarkers.

This textbook provides a comprehensive overview of the currently used concepts, approaches and technologies in the discovery and development of new treatments for the full spectrum of disorders of the central nervous system. It guides the reader through all essential steps, from finding an innovative idea, to the registration of a new drug. Divided into four sections, the book starts by presenting a broad perspective on current approaches in central nervous system (CNS) drug discovery. The second section addresses the generation of ideas for the identification of targets and novel treatment strategies; covers core functions in early discovery, and provides an example of a novel treatment paradigm: brain stimulation. The third section highlights strategies and technologies in translational CNS drug discovery. In an effort to bridge the gap between discovery and clinical development, it also covers brain imaging, EEG and cognitive testing approaches. The fourth section extensively discusses the clinical phase of drug development, covering the basics of early clinical testing for psychopharmacological drugs. The book’s final chapter addresses the registration for newly developed drugs. Written by experts from academia and industry, the book covers important basics and best practices, as well as recent developments in drug discovery. Offering in-depth insights into the world of drug development, it represents essential reading for early researchers who want to prepare for a career in drug discovery in academia or industry.

Psychiatric Disorders is written for researchers in both academia and the pharmaceutical industry who use animal models in research and development of drugs for psychiatric disorders such as anxiety, obsessive-compulsive disorder, depression, schizophrenia, bipolar disorder, ADHD, and autistic spectrum disorder. Psychiatric Disorders has introductory chapters expressing the view of the role and relevance of animal models for drug discovery and development for the treatment of psychiatric disorders from the perspective of (a) academic basic neuroscientific research, (b) applied pharmaceutical drug discovery and development, and (c) issues of clinical trial design and regulatory agencies limitations. Each volume examines the rationale, use, robustness and limitations of animal models in each therapeutic area covered and discuss the use of animal models for target identification and validation. The clinical relevance of animal models is discussed in terms of major limitations in cross-species comparisons, clinical trial design of drug candidates, and how clinical trial endpoints could be improved. The aim of this series of volumes on Animal and Translational Models for CNS Drug Discovery is to identify and provide common endpoints between species that can serve to inform both the clinic and the bench with the information needed to accelerate clinically-effective CNS drug discovery. This is the first volume in the three volume-set, Animal and Translational Models for CNS Drug Discovery 978-0-12-373861-5, and is also available for purchase individually. Provides clinical, academic, government and industry perspectives fostering integrated communication between principle participants at all stages of the drug discovery process Critical evaluation of animal and translational models improving transition from drug discovery and clinical development Emphasizes what results mean to the overall drug discovery process Explores issues in clinical trial design and conductance in each therapeutic area Psychiatric Disorders is available for purchase individually.

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.

According to the National Alliance on Mental Illness 1 in 5 adults (46.6 million) experiences mental illness in a given year. With that number steadily increasing every year it is vital that we invest into new drug discoveries as treatment options. At present the number of drugs available to treat individual with psychiatric disorders varies widely, and it is crucially important to identify new therapeutic targets in order to develop new, effective drugs. Therapeutic Discovery in Psychiatry aims to provide researchers with a complete guide to new technologies and techniques that can effectively manage risk and deliver of new drugs for psychiatric disorders. This book not only addresses issues of reproducibility, but addresses other topics including, drug profiling in vitro, examining drug targets, brain circuits and behavior, medicinal chemistry, drug formulation and pharmacokinetics, and much more. Therapeutic Discovery in Psychiatry is a prime resource for researchers who are trying to understand the field of psychopharmacology.
