Cynthia Dukes has an extensive and diversified medical background including 30 years of clinical research experience in vaccines, oncology and infectious disease.  Cynthia began her clinical research experience in 1985 as the Clinical Team Lead at Baylor College of Medicine’s Influenza and Respiratory Disease Research Center and NIH designated Vaccine Treatment and Evaluation Unit (VTEU) where she gained valuable experience in vaccine and antiviral drug development.  During her 10-year tenure at Aventis Pasteur (now Sanofi Pasteur), she was the clinical lead or product development manager for multiple vaccines and oncology research programs.  In addition, she oversaw US Pharmacovigilance group and was the clinical lead for the Medical Information group and the Clinical Trial Materials group.   Subsequent to Aventis Pasteur she was the Sr. Director of Operations at ILEX Oncology providing oversight of up to 100 oncology studies (targeted therapies and oncology vaccines).  While at ICON the past 15 years, Cynthia has been a significant contributor to the therapeutic areas of oncology, vaccines and infectious disease.   Whilst in pharma, Cynthia participated in more than 40 INDs leading to eight product approvals, including five vaccines, 2 oncology products and one immunoglobulin.   While at ICON she has provided strategic and management oversight on numerous pivotal studies leading to the approval of 9 vaccines and 5 oncology therapies. 

Investigative Sites / Networks

Our global investigator database includes over 1,900 vaccine investigative sites across more than 40 countries. ICON has established relationships with the major vaccine site networks in the US and has experience working with numerous site networks in Asia PAC and Europe as well.  This includes ICON’s phase 1 unit in San Antonio, TX and ICON’s recent acquisition of PMG Research in December 2015 that spans 12 metropolitan areas in the US, with over 48 physician practices.   The vaccine site networks offer ICON and the Sponsor a central point of contact that also supports sites centrally with start-up activities and during the lifecycle of a study.  Through these relationships we are assured faster response time, higher site quality performance while consistently meeting / exceeding enrollment expectations.
