Contract research organisations
Contract research organisations carry out parts of drug development on behalf of sponsors, and the rules that govern them start with the sponsor. Under 21 CFR 312.52 a sponsor may transfer any or all of its obligations to a CRO, and the transfer must be described in writing; any obligation not listed stays with the sponsor, and a CRO that takes one on faces the same regulatory action a sponsor would. The underlying sponsor duties in 21 CFR 312.50 include selecting qualified investigators, monitoring the investigations and promptly reporting significant new risks. Trial conduct follows ICH E6(R3) Good Clinical Practice: its principles and Annex 1 took effect in the EU on 23 July 2025, and Annex 2, on pragmatic and decentralised trials and real-world data, takes effect on 15 January 2027. FDA's 2013 guidance on a risk-based approach to monitoring shapes monitoring plans, and the CDISC TMF Standard, formerly the TMF Reference Model, gives a common structure for the Trial Master File. Submitted study data for FDA and PMDA use CDISC SDTM. Staff credentials come from ACRP (CCRA, CCRC, ACRP-CP and others) and SOCRA (CCRP). CRO teams also work inside the registries and safety systems: CTIS for EU trial applications, results submission to ClinicalTrials.gov, and electronic safety reporting to EudraVigilance.
