But can one really speak of tradition in innovation? And what if no one has decades of experience simply because the specific subject matter is brand new? It then comes to some of us to take the challenge and try to group all the available knowledge under one title. And this is what we did. We hope that this handbook will be useful to all and beg for everyone’s leniency if we have omitted or misrepresented any of the content. © 2019 Ethical GmbH - All Rights Reserved - more info at: https://www.endpointadjudication.com 2 1.

INTRODUCTION The present handbook is dedicated to all Clinical Research professionals who are or are likely to become involved in Clinical Endpoint Adjudication operations. We hope that you will find it helpful, easy to use, complete and accurate. With this publication we hope to bring a small contribution to the common effort for a world without disease. The FDA1,2,3 and the EMA4,5,6,7 have published several guidelines directly or indirectly describing the use of clinical endpoint adjudication and providing recommendations to strengthen the quality and validity of clinical data 3. CLINICAL OUTCOMES AND CLINICAL ENDPOINTS In clinical trial we often use the terms of “Outcome” and “Endpoint”, sometimes interchangeably. For clarity, in this manual we will define the exact meaning of each of these terms. 3.1. CLINICAL OUTCOMES Clinical outcomes are measurable changes in health, bodily function or quality of life that result from giving care to patients. Clinical outcomes can be measured by activity data such as hospital re-admission rates, or by agreed scales and other forms of measurement . The term “outcome” in clinical trials refers to a measured variable (e.g., peak volume of oxygen or PROMIS Fatigue score). 3.2. CLINICAL ENDPOINTS A clinical endpoint generally refers to one of the target outcomes of the trial that can be measured objectively to determine whether the intervention being studied is beneficial but may also refer to any disease or sign that strongly motivates the withdrawal of the patient from the trial, then often termed humane (clinical) endpoint. PRIMARY, SECONDARY, EXPLORATORY ENDPOINTS The primary endpoint of a clinical trial is the basis for making any therapeutic claims about the drug under study. All drugs have safety risks. The only reason that a patient would want to take a drug is if the drug 1) improves survival, 2) results in a benefit that was detectable by the patient (improvement in symptoms, improvement in functional capacity) or 3) decreases the chances of developing a condition or disease complication that is itself apparent to the patient and is undesirable (e.g. stroke). Therefore, a primary endpoint should be a direct measure of one of these and serve to claim an effect beneficial to the patient. Secondary endpoints investigate additional effects of the drug and are not used to support the principle claim. Secondary endpoints are endpoints for which the trial may not be powered nor randomized. However, it sometimes happens that a secondary endpoint result indicates an important effect of the drug that later becomes its primary purpose of use. Secondary endpoints align with secondary questions and need to be clearly defined up front. These allow to explore information obtained in the trial that may or may not provide definitive conclusions, but might guide the direction of future studies . © 2019 Ethical GmbH - All Rights Reserved - more info at: https://www.endpointadjudication.comhttps://www.endpointadjudication.com

  • Adaptive Designs in Clinical Trials: Why Use Them, and How to Run and Report Them Philip Pallmann1* , Alun W
    Pallmann et al. BMC Medicine (2018) 16:29 https://doi.org/10.1186/s12916-018-1017-7 CORRESPONDENCE Open Access Adaptive designs in clinical trials: why use them, and how to run and report them Philip Pallmann1* , Alun W. Bedding2, Babak Choodari-Oskooei3, Munyaradzi Dimairo4,LauraFlight5, Lisa V. Hampson1,6, Jane Holmes7, Adrian P. Mander8, Lang’o Odondi7, Matthew R. Sydes3,SofíaS.Villar8, James M. S. Wason8,9, Christopher J. Weir10, Graham M. Wheeler8,11, Christina Yap12 and Thomas Jaki1 Abstract Adaptive designs can make clinical trials more flexible by utilising results accumulating in the trial to modify the trial’s course in accordance with pre-specified rules. Trials with an adaptive design are often more efficient, informative and ethical than trials with a traditional fixed design since they often make better use of resources such as time and money, and might require fewer participants. Adaptive designs can be applied across all phases of clinical research, from early-phase dose escalation to confirmatory trials. The pace of the uptake of adaptive designs in clinical research, however, has remained well behind that of the statistical literature introducing new methods and highlighting their potential advantages. We speculate that one factor contributing to this is that the full range of adaptations available to trial designs, as well as their goals, advantages and limitations, remains unfamiliar to many parts of the clinical community. Additionally, the term adaptive design has been misleadingly used as an all-encompassing label to refer to certain methods that could be deemed controversial or that have been inadequately implemented. We believe that even if the planning and analysis of a trial is undertaken by an expert statistician, it is essential that the investigators understand the implications of using an adaptive design, for example, what the practical challenges are, what can (and cannot) be inferred from the results of such a trial, and how to report and communicate the results.

  • 3 Regulatory Aspects in Using Surrogate Markers in Clinical Trials
    3 Regulatory Aspects in Using Surrogate Markers in Clinical Trials Aloka Chakravarty 3.1 Introduction and Motivation Surrogate marker plays an important role in the regulatory decision pro- cesses in drug approval. The possibility of reduced sample size or trial duration when a distal clinical endpoint is replaced by a more proximal one hold real benefit in terms of reaching the intended patient population faster, cheaper, and safer as well as a better characterization of the efficacy profile. In situations where endpoint measurements have competing risks or are invasive in nature, certain latitude in measurement error can be accepted by deliberately choosing an alternate endpoint in compensation for a better quality of life or for ease of measurement. 3.1.1 Definitions and Their Regulatory Ramifications Over the years, many authors have given various definitions for a surrogate marker. Some of the operational ramifications of these definitions will be examined in their relationship to drug development. Wittes, Lakatos, and Probstfield (1989) defined surrogate endpoint sim- ply as “an endpoint measured in lieu of some so-called ‘true’ endpoint.” While it provides the core, this definition does not provide any operational motivation. Ellenberg and Hamilton (1989) provides this basis by stating: “investigators use surrogate endpoints when the endpoint of interest is too difficult and/or expensive to measure routinely and when they can define some other, more readily measurable endpoint, which is sufficiently well correlated with the first to justify its use as a substitute.” This paved the way to a statistical definition of a surrogate endpoint by Prentice (1989): 14 Aloka Chakravarty “a response variable for which a test of null hypothesis of no relationship to the treatment groups under comparison is also a valid test of the cor- responding null hypothesis based on the true endpoint.” This definition, also known as the Prentice Criteria, is often very hard to verify in real-life clinical trials.

  • Clinical Endpoints
    GUIDELINE Endpoints used for relative effectiveness assessment of pharmaceuticals: CLINICAL ENDPOINTS Final version February 2013 EUnetHTA – European network for Health Technology Assessment 1 The primary objective of EUnetHTA JA1 WP5 methodology guidelines is to focus on methodological challenges that are encountered by HTA assessors while performing a rapid relative effectiveness assessment of pharmaceuticals. This guideline “Endpoints used for REA of pharmaceuticals – Clinical endpoints” has been elaborated by experts from HIQA, reviewed and validated by HAS and all members of WP5 of the EUnetHTA network. The whole process was coordinated by HAS. As such the guideline represents a consolidated view of non-binding recommendations of EUnetHTA network members and in no case an official opinion of the participating institutions or individuals. The EUnetHTA draft guideline on clinical endpoints is a work in progress, the aim of which is to reach the consensus on clinical endpoints and their assessment that is common to all or most of the European reimbursement authorities in charge of assessing new drugs. As such, it may be amended in future to better represent common thinking in this respect.

  • Adaptive Designs and Small Clinical Trials
    ADAPTIVE DESIGNS AND SMALL CLINICAL TRIALS Christopher S. Coffey Professor, Department of Biostatistics Director, Clinical Trials Statistical and Data Management Center University of Iowa OUTLINE In this lecture, we will: I. Discuss the importance of adequate study planning for small clinical trials II. Understand what is meant by an adaptive design III. Understand differences among various types of adaptive designs – with special emphasis on those related to small clinical trials 2 OVERVIEW The wonderful land of Asymptopia: 3 OVERVIEW Small clinical trials present unique challenges. Small clinical trials are more prone to variability and may only be adequately powered to detect large intervention effects. As a consequence, the importance of adequate study planning is magnified in small clinical trials. It is often the case that more time is required during the study planning for small clinical trials. Critically important to have a true collaboration between clinicians and statisticians! 4 OVERVIEW To compute the required sample size for addressing the primary question of interest, we need to specify: Target power The significance level – α A clinically important difference that we wish to detect – δ Any additional nuisance parameters (variance, control group event rate, etc.) 5 OVERVIEW Small changes in design parameters may yield large changes in power. In general, one can increase the sample size to achieve a greater level of power. However, this may not be possible in small clinical trials and/or studies of rare diseases. In such instances, it is vitally important to minimize the variability of the treatment difference of interest. Novel designs also have great appeal in such settings.

Simulation studies. 2010 MSC: 00–01 The alternative proposed in this article uses a prediction error based on a measure of the weighted difference 99–00 between the observed treatment effect on the final endpoint and a model-based predicted effect. The measures can be estimated by cross-validation within the meta-analytic setting or external validation on a set of trials. Several distances are presented, with varying weights, based on the standard error of the observed treatment effect and of its predicted value.
