    Site Initiation Visit (SIV)

    A Site Initiation Visit (SIV) is the formal sponsor-led training and activation visit conducted at each clinical trial site immediately before the site is authorized to begin enrolling participants, typically following IRB approval and contract execution.

    The SIV covers protocol training, GCP review, IP handling, randomization, EDC and eCRF training, AE/SAE reporting, source documentation expectations, and emergency procedures. Completion of SIV with documented training is a prerequisite for the site's green-light to enroll.

    After SIV, the site is considered activated; activation date is a key startup KPI tracked across the portfolio.
