Ancillary Studies

The registry encourages proposals from individual investigators and institutions to carry out secondary or ancillary studies. Investigators who wish to initiate secondary or ancillary studies must submit a written request for approval from the Steering Committee. The Steering Committee will accept secondary and ancillary study concepts on a rolling basis, but will not authorize ancillary, secondary or other abstracts and papers to be submitted for publication/presentation until the primary study products have been accepted for publication.
