    Contract Research Organization (CRO)

    A Contract Research Organization (CRO) is a service organization that contracts with a pharmaceutical, biotech, or medical-device sponsor to perform some or all of the operational activities of a clinical trial, from protocol design through regulatory submission.

    Major full-service CROs (IQVIA, Labcorp Drug Development, Parexel, Syneos, ICON, PPD, Fortrea, Medpace) provide clinical operations, data management, biostatistics, regulatory, medical writing, and pharmacovigilance. Functional Service Provider (FSP) models contract specific functions rather than a full study.

    Sponsor-CRO oversight obligations under ICH E6(R3) require documented vendor governance, quality oversight, and transfer-of-obligations records.
