U.S. Expeditions and Explorations

U.S. Expeditions and Explorations (USEX) is a premier clinical research site network that specializes in the execution of Phase I-IV clinical trials for the pharmaceutical and biotechnology industries. Headquartered in Columbus, Ohio, the company is recognized for its high-quality data collection and rapid patient recruitment, particularly in the areas of infectious diseases and vaccines. In late 2021, USEX merged with IBR and LMC Manna Research to form Centricity Research, creating one of the largest integrated clinical trial site networks in North America. The organization provides sponsors with access to a large, diverse patient database and streamlined regulatory processes to accelerate drug development timelines. USEX played a significant role in the clinical testing of major COVID-19 vaccines and continues to support a wide array of therapeutic research programs.
