Nick Holford


Biography

Dr Holford is currently an Associate Professor at the University of Auckland. His research interests include population PKPD analyses of clinical trials of drugs and clinical trial simulation. He is currently developing the use of disease progress models for understanding clinical pharmacology with an emphasis on the effects of levodopa in Parkinson's Disease, drugs affecting post-menopausal bone loss, and the time course of response to anti-depressants.

A brief description of the presentation
It is widely accepted that anti-depressant drugs take some weeks to reach their greatest effect in the relief of depression. Clinical trials of anti-depressants often demonstrate marked responses to placebo treatment. The time course of the placebo response can be quantitated and the patterns of response used to understand the magnitude and time course of anti-depressant drug effects. Patterns of response within the time frame of a clinical trial include a monotonic improvement (decrease) in the Hamilton Depression (HAM-D) rating scale or an initial improvement with subsequent worsening. These patterns of response are partly explained by the design of the clinical trial especially the frequency of HAM-D observation. In the analysis of clinical trial outcome it is commonly assumed that the response to active treatment is additive to the placebo response. Clinical trial data were supplied by three pharmaceutical companies. Data included responses to placebo, marketed anti-depressants and drugs being investigated for anti-depressant effect. Based on the assumption that placebo response and active drug response are additive it is has been possible to describe the time course and magnitude of change in HAM-D attributable to anti-depressant drugs. A dose response relationship has been demonstrated with a rapid onset of action. There is no evidence that anti-depressant drugs take weeks to achieve their peak effect.

A brief description of the presentation
Value of model-based meta-analyses for drug development and approval
Modeling applications in pharmaceutical development have undergone some significant changes over the past few years. Application has shifted from analysis of independent trial results to integration of large quantities of data from multiple compounds and scaling between multiple endpoints. The purpose of which is two-fold: 1) to better understand the likely clinical safety and efficacy profile of the compound in development by borrowing information from competitors, pre-clinical experiments, and biomarker studies; 2) to better understand the competitive landscape and (clinical) value of the compound early in development. In this presentation several examples will be shown that illustrate the value of model-based approaches to drug development. Because of the value that has been illustrated by these and other examples, drug and disease models are starting to play a crucial role in guiding drug development decisions and regulatory interactions. They can play this role because the models provide an objective summary of the knowledge on the compound in development, disease, patients, and competitors. It is my belief that this model-based approach to drug development improves the efficiency of the development process by fully leveraging available information and by unleashing more efficient trial designs.

A brief description of the presentation
It will describe some of the opportunities and challenges awaiting pharmacostatistical model development, or population analysis, in the coming years. Promises lie in the increased amount of interest and confidence awarded to this relatively new technology in various areas of science and biomedical research, where it is widely regarded as a very useful tool and sometimes the only feasible avenue to extract information from data that would be otherwise impossible to gauge. Challenges lie in the sophistication of the technology, the difficulty of making drastic methodological advances and the relative scarcity of trained professionals, but especially of opportunities for training. Strategies and possibilities to increase the potential of population modeling and simulation in drug development and academic research alike will be discussed.

Hui Kimko


Biography

Dr. Hui Kimko works at Johnson & Johnson Pharmaceutical Research & Development in New Jersey from 2002 by joining Advanced Pharmacokinetic/Pharmacodynamic Modeling and Simulation Department. She teaches at School of Pharmacy of Rutgers University as an adjunct professor and mentors a PhD student of Department of Industrial & Systems Engineering. Before joining the company, she was an assistant professor at the Center for Drug Development Science of Georgetown University Medical School in Washington, D.C.
She got her PhD in Pharmaceutical Science from the State University of New York at Buffalo on Pharmacokinetic and Pharmacodynamic Modeling of Direct and Indirect Responses. She holds a B.S. degree in Pharmacy from Seoul National University and an M.S. degree in Biochemistry from University of California, Riverside. She edited the book titled Simulation for Designing Clinical Trials: A Pharmacokinetic/Pharmacodynamic Modeling Perspective (published by Marcel Dekker, Inc. 2003). The book explains how to optimize clinical trial design via pharmacokinetic-pharmacodynamic modeling and clinical trial simulation in order to enhance study success rate and, in return, help reduce the skyrocketing cost of conducting trials with human subjects. Optimization of clinical trial designs is her current interest.

A brief description of the presentation
The decision processes of designing clinical trials have followed a largely ad hoc manner, driven by empiricism and embracing concepts such as ‘what was done previously’ and ‘it has always been done this way’. In contrast, other disciplines have been effectively designing experiments using statistical techniques to aid design for many years but it is only recently that these methods have filtered into the clinical pharmacological arena. Simulation has become a powerful tool for the practitioner due to its generality of application to a wide array of potential problems. In addition, simulation gains credibility with the non-scientist since it can be explained in essentially non-scientific terms, which allows its transparency to be grasped with ease. It is not surprising, therefore, that clinical trial simulation (CTS) has been used in designing clinical trials in drug development (1-2).
CTS is to generate responses of virtual subjects by approximating (a) trial design, and (b) human behavior, (c) disease progress and (d) drug behavior using mathematical models and numerical methods. The trial design that is needed for CTS includes to-be-decided dosage regimen, subject selection criteria, study period and study size. Human behavior includes trial execution characteristics such as adherence in drug administration (pertaining to enrolled patients) and missing records (pertaining to the investigators). Disease status may change during a trial, for which a disease progress model may need to be developed. The drug behavior in the body is generally characterized by pharmacokinetic (PK) and pharmacodynamic (PD) models. These models are developed from prior experience and/or prior data.
Understanding the relationship between antibiotic concentration and the antimicrobial effect is necessary for eradicating the pathogen. The Monte-Carlo approach represents the state of the art methodology in anti-infective research for dose-selection of new drug entities. These methods take the exposure-response relationship into consideration and allow examination of what if scenarios such as the effect of administering a dose not studied during development. Monte Carlo computations are fairly rigorous and explicitly account for sources of variability that can impact the possibility of successful treatment with a new drug entity. The sources of variability include a) inter-subject PK variability; b) non-linear bioavailability due to various solubility rate limited absorption; c) formulation and food effect on relative bioavailability; d) within-species pathogen sensitivity to the drug, e) between-species pathogen sensitivity to the drug; and f) natural occurrence frequency of pathogens in a clinical setting. By taking into account sources of biological variability and by recognizing the pharmacological interaction between the pathogen, host and drug, an educated decision can be made regarding a dosing regimen that is most probable of succeeding in a future clinical trial.

A brief description of the presentation

Integration of PKPD modeling and simulation (M&S) in new drug development programs may afford one or more of the following advantages over traditional empirical development approaches: (1) enhanced learning about relationships among drug dosage, metabolism, and tissue concentrations to biomarkers and clinical measures of safety and effectiveness, (2) testing of assumptions critical to safety, effectiveness and market acceptance, with respect to drug actions, dosage regimens, routes of administration, etc, (3) informative trial design and optimization of trial design features, (4) enhanced data analysis for learning and confirming from all trials, and (5) enlightened regulatory guidance, review and approval of M&S-intensive regulatory submissions.

Despite the above listed advantages, utilization of rapidly advancing PKPD M&S technology by the pharmaceutical and biotech industries and regulatory agencies has been slow and incomplete. This presentation will identify barriers to greater integration of PKPD M&S in drug development and regulation, factors that may enhance acceptance, and avenues for further advancement of advantageous incorporation in future new drug development programs and regulatory procedures.

A brief description of the presentation

An adaptive design allows an investigator to monitor the acruing efficacy data to make important decisions (such as sample size, dose levels, etc) concerning the future course of the study. Thus, the investigator can have the options to make adaptive changes to the initial design with verification of design assumptions (variance, effect size, covariate effects, etc.) and to either terminate for futility, change dose levels, drop ineffective arms, or divert key resources to more promising studies. By taking advantage of these opportunities, the investigator can reduce the clinical study cost or achieve the study objective more efficiently. An adaptive design is employed in a phase II study to make a go/no-go decision as well as to characterize the dose reponse. A simulation study is used to demonstrate the utility and advantage of the proposed adaptive design study.

A brief description of the presentation
Two analytic strategies can be taken to the analysis of multi-response data: a multivariate output model can be fit to all the response components simultaneously, or each response component can be fit separately to a univariate output model, conditioning in some way on the non-modeled components, the so-called forcing function approach. Focusing on a special case of multi-response model corresponding to a pharmacokinetic physiological flow model, this presentation will propose an algorithm for applying forcing function approach to multi-response data from a physiological flow model, examine the performance of forcing function approach vs. simultaneous approach, and make recommendations regarding the use of forcing function for multi-response data analysis.
