WCG's strength is scale — broad service lines and infrastructure built for large, global, multi-region programs. Elemental IRB concentrates on responsive US review: a published 3–5 business day expedited timeline, rolling review, direct access to reviewers, and a fully digital portal with real-time status tracking.
WCG does not list IRB pricing publicly; fees are custom-quoted per submission and often include separate amendment, continuing-review, and expedite charges. Elemental IRB publishes a flat $1,500 expedited / $4,000 full board rate, with minor amendments and continuing review included and no expedite surcharge.
