Improving Drug Development Using Patient Adherence Data in Clinical Trials

6 - 7 May 2008, Washington, United States

Introduction

Data from trials and practice show that ambulatory patients frequently underdose, either by: never starting dosing, omitting scheduled doses, or premature cessation of dosing. Routine methods fail to detect most of these errors. Yet variable dosing histories are a major source of variance in drug response, confounding the interpretation of all dose/time-dependent trial outcomes, eg, estimates of PK parameters, dose-dependent efficacy, regimen definition, dose-dependent toxicity. Properly analyzed dosing histories can improve learning-phase trials.
