Clinical Trials; Definition The NIH defines a clinical trial as a prospective biomedical or behavioral research study of human subjects that is designed to answer specific questions about biomedical or behavioral interventions (drugs, treatments, devices, or new ways of using known drugs, treatments, or devices). Web site; www.Grants.nih.gov/grants/funding/phs398
1990 - 5000 pharmacists and physicians conducted clinical trials of a new drug 2000- More than 60,000 medical professionals are principal investigators
Types of clinical Trials • Phase I/II/III clinical Trial • Behavioral medicine study • Study of a new procedure • Trial of new devices
Phase I Clinical Trial • Phase I clinical trials test a new biomedical intervention in a small group of people (e.g., 20-80) for the first time to evaluate safety (e.g., to determine a safe dosage range and to identify side effects). NIH definition
Phase I Trial and Pharmacokinetic Study of BMS-247550, an Epothilone B Analog, Administered Intravenously on a Daily Schedule for Five Days Jame Abraham, Manish Agrawal, Susan Bakke, Ann Rutt, Maureen Edgerly, Frank M. Balis, Brigitte Widemann, Louis Davis, Bharat Damle, Daryl Sonnichsen, David Lebwohl, Susan Bates, Herb Kotz, and Tito Fojo National Cancer Institute, Bethesda, MD JCO May 1 2003: 1866-1873.
Phase II Clinical Trial • Phase II clinical trials study the biomedical or behavioral intervention in a larger group of people (several hundred) to determine efficacy and to further evaluate its safety.
Phase II Clinical Trial of Ixabepilone (BMS-247550), an Epothilone B Analog, in Metastatic and Locally Advanced Breast Cancer • Jennifer A. Low, Suparna B. Wedam, James J. Lee, Arlene W. Berman, Adam Brufsky, Sherry X. Yang, Marianne S. Poruchynsky, Seth M. Steinberg, Nitin Mannan, Tito Fojo, Sandra M. Swain • National Cancer Institute • JCO Apr 20 2005: 2726-2734.
Phase III trials • Phase III studies investigate the efficacy of the biomedical or behavioral intervention in large groups of human subjects (from several hundred to several thousand) by comparing the intervention to other standard or experimental interventions as well as to monitor adverse effects, and to collect information that will allow the intervention to be used safely.

Claude Bernard (1813-1878) The first requirement…in practicing experimental medicine, is to be an observing physician and to start from pure and simple observations of patients made as completely as possible. “An Introduction to the Study of Experimental Medicine” 1865. He is considered as the "Father of Physiology”.
