List of Contract Research Organizations in the US (2025)

The US remains the epicenter of research globally. Many contract research organizations in the US such as IQVIA, Syneos Health, Medpace, ICON plc, Fortrea, Worldwide Clinical Trials, Labcorp, PPD (now part of Thermo Fisher Scientific), and Charles River Lab, are top global CROs. They have many offices and research locations in different countries.

Though all the states in the US conduct clinical trials, some states such as New Jersey, North Carolina, Pennsylvania, Maryland, California, and Massachusetts, have a significantly higher concentration of Clinical Research Organizations (CROs).
