Responsible for establishing and administering a policy on the protection of human subjects has been delegated by the Chancellor to the Human Subjects Committee. No activity involving human subjects is to be undertaken unless the HSC has reviewed and approved such activity. Even if the Committee approves an activity it may prescribe restrictions or conditions under which the activity must be conducted, particularly as it relates to children, prisoners, or other special population groups. The Committee will review the conduct of the activities at timely intervals. The nature and frequency of reviews will be determined on the basis of the risks involved to assure that the activity is being properly conducted and that the Committee’s stipulations are fulfilled. Continuing activities must be reviewed at least annually. The Committee may order the suspension of any approved activity if, in its opinion, the relative risks outweigh the potential benefits.
