BACKGROUND

The original regulatory system applied to grants. Each investigator milf movies
was required to seek approval from his or her institutional IRB. Thus, each IRB reviewed the protocol for one of its own investigators.

The 1981 FDA regulations required IRB review for clinical investigations. While many clinical investigations were single site, an increasing number were not. Central IRBs work with both sponsors and investigators to accomplish the same goal as internal IRBs: protection of human subjects.

Two Possible Responses:
There are two usual relationships.

a) Preferred relationship: (E&I is named the "central" IRB for the study by the sponsor)

The sponsor may elect to work directly with E&I to conduct review of one or all of the studies from that sponsor and for one or all of the investigators on the study. The sponsor is considered to be E&I's "client." Review of the study protocol (design, etc.) is negotiated between the IRB and the sponsor's representative. When approval is granted, it is with the condition that it cannot be initiated at any individual site without separate review of the principal investigator. Likewise, modifications are first presented to the IRB.

An IRB is expected to have a direct relationship with investigators. Each investigator is expected to submit an application to the IRB requesting approval to participate in the study.  In this scenario, all sites may be set to expire at the time the master approval expires, which may be much less than a year. Handling multiple site expirations at one time can less of a burden for the sponsor and the IRB; our processes also work to accommodate any late arriving investigators.

b) Relationship without direct sponsor involvement: (E&I is selected by the investigator)

Adhering more closely to the traditional model, some sponsors continue to keep at arm's length from the IRB. These sponsors insist that each investigator submit the entire study and investigator packet individually.  The major problem with this model is that the IRB must negotiate each concern and requested change individually with each investigator who, likely, will each refer the question to the sponsor. Although this is traditionally done when there are multiple IRBs for multiple investigators, when working with a central IRB it is very redundant, time consuming, and confusing in addition to being costly.

NON REVIEWABLE SITES – LOCAL IRB

E&I has a very strict policy about review of sites that have their own internal IRB.  E&I will not ever knowingly approve an investigator for work at a facility where another IRB has prior jurisdiction without agreement from that IRB. Put another way, our IRB will not step knowingly into another IRB's jurisdiction without permission. Waiver and certification from a local IRB may be presented on our form or in a letter format on the local IRB's letterhead. The waiver and certification assures us, in writing, whether or not there is an IRB and, if so, whether it agrees to defer to our IRB.
