AMR Lexington is a multispecialty clinical research site located in Lexington, KY.  The ability to recruit evaluable patients rapidly, maintain high retention rates, and produce high-quality study results in a timely manner has earned AMR Lexington a sterling reputation as one of the nation’s most respected clinical drug research facilities.  The company has conducted trials for every major drug company in the U.S. in addition to numerous international companies and U.S. governmental agencies.


AMR Lexington was originally founded in 1991 as Central Kentucky Research Associates (CKRA) by Deborah Dyer, RN, BSN, and the late Jacqueline Smith, RN, BSN.  CKRA was Kentucky’s first independent clinical drug research facility and one of only a few such facilities in the nation that was owned and operated by women who were not physicians.  In 1994, CKRA was asked to join the prestigious Alliance for Multispecialty Research (AMR); an elite network of clinical research sites whose membership is by invitation only and the culmination of a rigorous peer review and acceptance process.  Today, AMR is an industry-leading company comprised of 16 of the most highly experienced clinical research centers in the United States and serves as a hub for shared marketing, business development, and best practices.


AMR Lexington has conducted over 500 Phase I-IV clinical trials in the areas of Allergy, Cardiology, Dermatology, Endocrinology/Metabolism, Gastroenterology, Infectious Disease, Musculoskeletal Disorders, Neurology, Pain Management, Pediatrics, Respiratory Disorders, Smoking / Tobacco Studies, Urology, Vaccines, and Women’s Health.
